Thermal Design specifications and properties of electronic components and materials (Part 2)

The modelling technics currently used have at least two different methods for creating real models for thermal design. One method uses direct geometrical/material analyses to make thermal model for components and the other method uses thermal resistor/capa-citor networks for example the DELPHI-project. Both of these methods should be possible in component level specifications.

The European co-operative project DELPHI /Rosten et al/ is an example of an activity where the responsibility of the thermal design has been attempted to be shared between the supplier of component and the end user.

The specification system for thermal specifications of electronic components and sub-systems and the applicable tests/measurement methods should cover following areas:

- Component specifications
- Interface specimens and materials (heat conducting specimens, thermally conductive insulators) and their specifications and models
- Subsystems (Printed circuit boards, units, rails)
- Heat sinks and fans.
- Material specifications (materials of components and other parts of electronics)

Some guidelines are needed for the thermal specification of PCB and subsystem level. It should be kept in mind that all relevant heat transfer mechanisms are treated, conduction, convection and radiation, when components are positioned on PCB. Monitoring the work of existing groups generating thermal models - DELPHI, SEED, JEDEC; SEMI, and standardising these different methods will be an important task for this research project and CENELEC.

1. ECONOMIC AND SOCIAL BENEFITS

A good thermal design of electronics is crucial on the reliable and safe operation of equip¬ment. The current situation makes it difficult to design electronics effectively because of the lack of standardised thermal specifications of electronic components and heat conducting materials. The ever increasing power density of electronics causes large difficulties for the designers who need more accurate and reliable information of thermal properties. The existence of standards could make it much more economical to make good thermal design.
 
2. SCIENTIFIC AND TECHNOLOGICAL OBJECTIVES

The RTD work-programme should contain the following tasks:

1. Definition of specifications of the thermal properties of electronic components

1.1 Parameters

Definition of the specific thermal parameters concerning thermal design of components, assembled printed wiring boards, materials and test methods.

1.2 Units

Units (and symbols) of the thermal parameters concerning thermal behavior and also design of components, assembled printed wiring boards and various materials shall be defined.

2. Thermal specifications of electronic components and interface parts

2.1 Evaluation of various package types of electronic components

Evaluation of package types used in electronic components shall cover such packages which probably have use also in the future. Evaluation concentrates on finding possibilities to use some simplified geometric thermal model for these package types. Therefore the project has to find and develop some principles how such simpilification should be done.

2.2. PBGA-package evaluation of simplification of detailed geometric models

8. IMPORTANT ADDITIONAL INFORMATION

To get a reasonable amount of progress in this area, a minimum of three intrested parties is necessary.

Close connections with CENELEC should be demonstrated in the proposal, and ensured during the proposed workplan, in order to properly match the requirements of industry and the evolution of technology.

Different Types & Uses of a Pressure Vessel

For those who are not aware, a pressure vessel has many commercial and industrial uses that individuals can benefit from in both the short as well as the long run. These vessels come in handy where the matter of immediate heat transfer and the storage of high pressure gas are concerned. Pressure in these vessels can be inserted from a wide range of different kinds of sources, for instance direct and indirect. Therefore, depending on the type of material for which the gas storage or heat transfer is required, these vessels should be used as they truly are very efficient and effective in the overall process.

Types of Pressure Vessels

When it comes to the type of a pressure vessel, it has several ones that are all different in their own way. While some are able to handle a particular level of pressure, others can hold on to a significant amount of pressure for a long period of time. Best used for high end industrial uses, the different kinds of these vessels mainly include thick and thinned walled pressure vessels. The description of these vessels includes being rather thin. Moreover, both of these vessels are also described to be slim cylinders that allow the storage of gas and heat transfer at all times.

Thinned Walled

A thinned walled pressure vessel is not hard to recognize if people understand how it looks like. The thicker one is separated from this kind of vessel due to the fact that it is clearly much thinner in comparison. Its sleek, cylindrical shape makes efficient and fast heat transfer and gas storage, which is precisely why it is used in so many industrial applications these days. However, checking out the ratio of the wall thickness is something that is necessary for the purpose of differentiating thinned walled ones from the thick ones by a long shot. Experts usually recommend individuals to check out the diameter of these walls in order to see how much it is for the purpose of finding if a vessel is a thinned or thick one. This kind of vessel is said to have swifter and more efficient way for the storage of gas and transferal of heat.

Thick Walled

On the other hand, the thick walled pressure vessel is quite as beneficial as the thinned walled one. These are effective in the matter of transferring heat and storing high pressure gas, and while individuals may find the thinned walled vessels much more efficient, these ones really do not fall behind as much, too. The cylinder for these vessels is definitely bigger in comparison with the thinned walled ones, which means that the diameter as well as the ratio of this particular sort of vessel is most definitely greater than that of the thinned walled vessel. One thing to note about this kind of vessels is the fact that it is not a common one, which means that it isn’t used nearly as much as the other and neither is it found as easily for purpose of using it for industrial applications, whereas the thinned walled vessels are a very commonly found vessel that is used time and time again whenever needed.

Other Uses of Pressure Vessels

These vessels are also used for storing gases under pressure as well as liquid vapors. Engine cylinders and steam boilers are the others place where these vessels can be seen to be used in abundance. Moreover, these vessels are also used in chemical plants and most importantly, they are used for storing chemicals in massive amounts. Petrol, diesel and all such commodities are also usually stored within these vessels, which is why they are amongst one of the most essential type of equipment these days.  

Tips for Plate Cooler Gaskets

When purchasing a plate cooler gasket, one needs to keep a number of things in mind since it is important to get all the right components for the equipment to work properly. Communication with the manufacturer is very important since that is how one will know what type of gasket will work best for their equipment. The manufacturer will be able to tell the buyer about the gaskets they have in stock and which type will work great with their equipment. Moreover, the buyer will be able to tell the manufacturer about his/her own requirements. This will ensure that only the most compatible components are ordered.

Coming to compatibility, it is important that the buyer himself checks the compatibility of the plate cooler gasket as well. Most importantly, chemical compatibility needs to be checked. The buyers need to make sure that the heat exchanger component and the liquids they use in labs work great with all equipment to be bought. Many of these components will contain the pH of 316, which is the element for stainless steel. Most of the chemicals used during labs are unable to harm stainless steel with a pH of 316. However, chlorine, which is often used in lab experiments can corrode the steel and thus, one needs to ensure a higher pH if they are to work with the aforementioned chemical. Also, the food industry uses certain chemicals to clean their equipment which may not work with a 316 pH.

Try and avoid situations which result in pressure spikes in the plate cooler gasket. 

Some manufacturers do make allowances with the engineering and the design, allowing the component to withstand some pressure but mostly, it is better to ensure that there are not many pressure spikes in place. These can be caused by immediately closing off a valve, a water hammer. These precautions will have to be taken otherwise, it can result in very lethal leakages that can even result in blowouts. Do not allow pressure changes which are more than one hundred and fifty psig every minute. Relief valves can be sued as remedies in such situations. 

Make sure that the plate cooler gasketremains clean and regularly check it for particles. Even though it is recommended that one thoroughly checks through the entire thing and eliminate particles of all kinds, it is okay if one misses out a couple of small particles. However, the large particles are what users will have to be wary about. This is because the movement of fluid within the equipment can be badly hampered if these large particles are blocking the way. The movement of the fluid can stop and one particular zone in the gasket can overflow, causing leakages and emergency situation, consequently. Make sure the particles are no bigger than 0.0625 inches. In an open tank, one will have to be even more careful.

Make sure that the integrity of the frame dimensions and plate pack dimensions in the plate cooler gasket are checked periodically. This can be vital to stop leakages when they occur and sometimes, even before they actually take place. The manufacturer will provide the details on the dimensions and the pack when the purchase is carried out and it is highly recommended that corks and screws are checked every so often to ensure that the necessary safety precautions are taken. Also, the equipment must be checked for damage and corrosion so that one can know when the equipment will have to be replaced.

A plate cool gasket is a very important component in a number of equipment and one must use it properly and after checking and inspecting it properly. 

Reasons for Using an Oil Cooler

The oil cooler is currently being used for a wide number of reasons and the most prominent one includes the cooling of oil within high end plants as well as for day to day engine car oil cooling. These coolers are currently being used for industrial applications and they have turned out to be an excellent source for acquiring cooled oil, specifically in places where it is scarce and hard to be produced otherwise. As one of the most efficient cooling systems, these are majorly used in plants as well as places like that, particularly where cooling systems are needed the most due to difficult environmental conditions. These also come in handy for car engines and are heavily used in engine lubrication as well as cooling engine oil.

Low Maintenance

The oil cooler is highly known to have exceptionally low maintenance costs. This means that those who install it are not going to have a hard time in taking care of it in both the short and the long run. It is due to the fact that these coolers are in no immediate need of cleaning and it is only to be done once a while, only when it is required the most. However, when the coolers demand cleaning, it is to be done instantly since the inside of the equipment may get clogged, leaving the cooler lacking in performance in the near future. Since the cost of the maintenance is low, it is also going to save individuals a lot of money in the beginning and later on.

Keeping Oil Pure

This is considered to be one of the best ways for cooling liquids, mainly oil within engines. Therefore, one thing to be sure about is that the oil cooler does not pollute the oil in any way. While many cooling systems for oil may leave it polluted, this cooler does not in any way compromises its cleanliness as that can completely affect it, that too in a negative way. These are generally used in power plants since such places use these in abundance on a day to day basis and also use them for other prominent and high end industrial uses. These are also used for car engines.

Less Time Consuming

The oil cooler saves individuals from cooling off oil through any other means, which is definitely going to save a good amount of time. Moreover, it also saves a lot of money as these coolers tend to do the task all on their own, without the aid of any other machine, device or equipment. Hence, these truly are to be in high end plants where the production of cooled oil is a must in both the short as well as the long-term. Also, there is absolutely no need to wait a long while in order to achieve cooled oil as these coolers complete the job pretty soon.

The downside however still exists with oil cooling technology that haunts its usefulness in some extreme cases. For example, if the temperature of the object that is to be cooled is heated to temperatures higher than 200 degree Celsius, oil cooling technology throws in the towel and fails to do its job. In some cases it also leaves achy deposits. Water as a coolant on the contrary is much safer to use when it comes to deposit free cooling. Also, water is far more abundantly available than oil and is way cheaper too. This makes oil cooling technology a second place when it is compared with water based cooling technology. Water coolant can also withstand more engine heat then can oil.  

Heat Exchanger FAQs and Answers

Many people who purchase heat exchangers and other such appliances often complaint that they have not gotten the thing they were looking for or that the seller has not given them the item he had initially described. While it is true that the seller may trick customers, it is also widely known that many customers only have themselves to blame for the deceit. This is because they do not conduct enough research before they go out to purchase the product and hope to believe everything that the seller tells them about it. Since it is very important to conduct proper research, a list of the most Frequently Asked Questions about the heat exchanger have been listed and answered.

What is it?

In the easiest possible words, heat exchangers are things that transfer heat from one appliance to another, or from one medium to another. For example, heat exchangers installed in a swimming pool will use hot water stored up in a boiler to heat up the water in the pool or a Jacuzzi. Also, hydraulic coolers will use cold water or air to make sure that the heat of oil used to run the machine is cooled down as well. The actual exchange of energy happens through the conductors that are separating the two opposing forces. Conductors may take the form of tubes or pipes through which fluids run.

What are the types?

Many people also want to know the man types of heat exchangers available in the markets today. To begin with, there is the shell and tube heat exchanger. Many small sized tubes are contained inside a shell in the shape of a cylinder. A tube stack is used to make sure that the tubes are properly positioned inside the shell.In many cases, the tube stack lets the tube bundle grown larger or smaller in accordance with the amount and temperature of the fluids within.

Moving on, plate heat exchangers are probably the most common form of heat exchangers used today. They are quite similar to the typical shell and tube exchanger but instead of tubes, it uses a stack or collection of plates. They may be gasketed if the fluids and the setup inside the exchanger allows the change. They are mostly built with stainless steel and are perfect for refrigerators.

Lastly, there are the air cooled heat exchangers that are widely used in cars and other such vehicles to keep the engines cool and functional. They are mostly placed in areas where there is no source of cool water available at all times. They may sometimes bring together water, air and charge air coolers into a single entity to make sure that lesser space is consumed for the same effectiveness. Cool air comes from a fan or the sir coming into the cooler when the vehicle moves.

Which fluids are needed?

Not all liquids are able to work within a heat exchanger and one will have to select the fluids appropriately. To begin with, one will have to consider where the specific exchanger is being used and the different appliances used in the exchanger itself. Material used to construct the exchanger will also matter a lot. The most common types of fluids include simple water, sea water and even oil (especially in air cooled exchangers) but other fluids which are more corrosive may also be used. These include chorine induced water and other acids. They may work better temporarily but will, undoubtedly, damage the exchanger.

How to increase the life?

Since many heat exchangers, specifically those bought for bigger equipment and appliances, are so expensive; many people wish to know how they can care for the exchanger to extend its life. The only way to do this is through regular checks, maintenance and repairs so that no damage comes to the exchanger and danger is discovered before it occurs.  

Features to Look for in Fresh Water Generators

One of the most prominent reasons for using a fresh water generator is to convert sea water to fresh water in a short period of time. While doing it manually is almost nearly impossible, these generators have been particularly manufactured in order to carry out this task at all times and that too, without giving people much issues in the matter. These generators are currently available in the market at different prices which always tend to vary from brand to brand and model to model. Many factors have to be taken into thorough consideration before purchasing this generator as it has a lot of distinctive features.

Interface

Something that really must be noticed and checked before investing in a fresh water generator is the interface. The interface of generators always varies from one another and the best one is most definitely going to have an easy to follow interface that displays everything without creating an issue. Most generators, however, have intricate interfaces, which is why a lot of people may find it difficult to use them in the first place. However, since the technology has progressed by a long shot these days, high end generators for converting sea water to fresh water now have easy to comprehend interfaces which makes using them very simple on a day to day basis.

High Efficiency

The efficiency of a fresh water generator is another significant thing to be checked thoroughly beforehand. Since the conversion of sea water to fresh water can be a long process at times, the output is equally important. Due to that, it is important for a generator to have a good amount of efficiency in the first place. Generators having high end efficiency produce the best results and that too, in the least possible time. Generators with high end efficiency as a feature are always a great purchase.

High Quality Motor, Pipes & Pumps

Features such as piping as well as the motors must be reviewed in great detail as that is directly linked with the conversion of sea water to fresh water. Generators with high end pumps, motors as well as pipes are definitely more efficient and less time consuming, which makes them a great investment for anyone who is looking water to have fresh water in abundance at all times. A fresh water generator needs energy efficient motors as well as top quality pipes in order to provide positive results without giving any trouble to people.

Easy Usage

An essential thing for people to know is that a fresh water generator must be always be easy to use and control on a day to day basis. A lot of such generators can be hard to understand, making it impossible for anyone to run them without struggling a lot. This can be fully eliminated by going for a generator that has been ranked high by the general public. General reviews as well as testimonials can always be found online and that surely is going to help people in the process of choosing the best generator that converts sea water to fresh water in record time.

The Benefits of a Heat Exchanger

The newest technology in the world of heat exchangers has been truly revolutionary and it has created a lot of ease for its users. Heat exchangers are mainly used to transfer heat from one machine or device to another one. Many people do not know this but a heat exchanger is one of the main things used in a number of household appliances. Many of them use it to transfer energy and to make sure that the appliance runs smoothly and effectively. There are a number of different heat exchangers that people can buy off the markets. However, there are some qualities that all heat exchangers have which all users will benefit from.

Adaptability

The newest technology in heat exchangers, especially those that operate as plate heat exchangers are incredibly friendly to change and are all highly adaptable. This makes them flexible and allows them to be used in a number of different tasks. Most importantly, heat exchangers have become more and more adaptable to size. Before the newest models became available, it was highly common for heat exchangers to be about the size of a huge refrigerator. Now, however, they are compact and are swiftly reducing in size, allowing them to be used in gadgets that are smaller and smaller. They are now commonly used in small, portable heat generators and air conditioners.

Maintenance Costs

Another plus point of the heat exchanger is the fact that it does not cost as much to buy as it used to. Before the advent of the latest technology used in heat exchangers, it was common practice to use expensive fabric in its manufacture and thus, it cost a lot of money. Now, however, the fabric used to construct the heat exchangers have fallen in price and thus, the price of heat exchangers has gone down as well. Moreover, the maintenance costs of the appliance are very little as well. Plate exchangers can be removed very easily and cleaned up quickly. This is a rather new development as earlier it used to be very expensive to clean heat exchangers.

Many Uses

As described before, heat exchangers have many different uses since they are so very flexible to use. They are used in things like microwaves and air conditioners. They can be used in both ACs and in heat generators. The model and basic idea behind it is very simple and thus, one can easily adapt the basic model and make it work in a number of different appliances. Heat exchanger models are so adaptable that they are everywhere to be found and are currently used in a number of different appliances by people. For example, it can be used in domestic appliances as well as nuclear and chemical plants – all at once. 

Materials

An average heat exchange system is available in a number of different materials as well. Each specific designed is made to fit a specific use or specific system of an appliance. Nickel, titanium, stainless steel, Inconel, Tantalum and palladium are just a few of the materials out of which this can be constructed.

Even though an average heat exchanger has many different benefits, there are a few limitations to the appliance as well. If the two substances have a very varied temperature, it is likely that the heat exchanger may cause a few problems. It may end up leaking out water or even a hazardous substance in a safer environment. Thus, it is important to make sure that before putting the thing to actual use, one makes sure that they have read the safety manuals and have taken the necessary steps described in them. It is important to remember that one needs to be able to handle emergency situations. 

Fresh water generator – Invention of the century

The earth is seventy percent water and though it may seem that there is water everywhere, only three percent of this water is fresh water and drinkable and the rest is all salty water which is not fit for drinking. Years ago, old cargo ships were required to carry huge supplies of fresh water for their crew when departing upon a long voyage. If there were a ship that would run out of water for drinking, it would be carrying a very miserable crew indeed. However, this has changed thanks to technology as in today’s era; almost all commercial ships are equipped with a fresh water generator. A fresh water generator is basically a kind of evaporator that converts salty sea water into water that is drinkable and fresh.

The whole idea behind a fresh water generator is actually quite simple. It serves the purpose of evaporating sea water with the use of a source of heat in order to separate the pure water from the salt, sediment and other elements. A diesel engine is usually used by fresh water generators as the heat source. However steam can also be used to serve the same purpose. Since fresh water generators often make use of existing heat in order to run, the cost of operation of these machines is quite low.

The fresh water generator has two main elements which are the heat exchanger and the condenser respectively. The heat exchanger serves the purpose of evaporating the water and the condenser condenses the fresh water vapor, turning it into water that is drinkable. The condenser is the element that cools down the vapor which is simply done by using cold sea water to cool the outside of the machine.

Fresh water generators should include a feature that can be used to monitor or check the salinity of the water that is processed. If the salinity were to exceed a particular level, which is usually between one and ten parts per million (ppm), the unit would automatically take the water back to the feed line so as to run it through the complete cycle again.

Fresh water generators these days are increasingly being used in desalination plants. These are usually and typically located in coastal areas and serve the purpose of providing the local community with fresh drinking water. They have become quite common in some communities of California as well as in the Middle East. As a response to drought as well as the concern over the availability of water in the growing number of cities, more and more desalination plants are likely to be built in the near future. One drawback though is that the costs that are involved in these desalination plants are quite high and so they are considered by communities only in those situations where they are faced with shortages of water from the sources that are traditional. So this poses a problem when the construction of desalination plants is given a thought as people only build them when needed.

In passenger and merchant ships, the application of fresh water generator becomes even more important and crucial. The ship based fresh water generator uses heat from ship’s engine and salt water from the sea and makes it drinkable through either evaporation method mentioned above or through the reverse osmosis process that is more expensive but produces bulk amount of drinkable water essential for drinking, washing and consumption of masses. All in all, the fresh water generator may end up preventing a world war by providing drinkable water made from all the water in the world thus eliminating the scarcity of this precious life source.  

Important Parts of a Tube Bundle & their Uses

A tube bundle is used for many reasons, and one of the most important ones includes heat exchange in various commodities. These bundles are available in a wide range of different sizes, diameters, shapes, materials as well as designs. Choosing the most appropriate one depends on whichever industrial application it has to be used for in the first place, which has to be decided by the user. There are many parts of these bundles, all of which are unique in their own way and without them; these bundles tend to not work as efficiently as they do otherwise.

Tubesheet Material

Being a part of the tube bundle, the tubesheet thickness is something that can be easily measured. While the thickness may vary always, individuals who wish to use these bundles can always select the type of tubesheet thickness which suits them best and that usually tends to depend on the type of application it is being used for. The diameter can also be checked without having to face any issue and for those who are interested in knowing the actually thickness of the tubesheet which is majorly found in these bundles, it varies from 5” to 3” thick at best.

Presence of Bolt Holes

On the other hand, these bundles also are inclusive of bolt holes which can be found in abundance. People should be aware of the fact that the bolt holes always tend to go around the tubesheet and on through it, which is a common misconception amongst a lot of individuals who decide to use the tube bundle for a variety of different reasons. However, some of these bundles many have bolt holes and on the other hand, some may as well not have them too. Although knowing the size of the bolt holes present in these bundles along with their sizes and length is exceptionally important.

Materials of the Tube

Individuals going ahead in order to use a tube bundle should always check out the tube materials beforehand. This basically ensures the material that has been used in the manufacturing of the bundles in the first place. Mostly, they are made of cooper and that is easy enough to find. However, in case these ones are not available for some reason, there is a wide range of other tube materials which are available for the convenience of users. These materials generally are inclusive of carbon steel, titanium, cupro-nickel and many more which are equally as effective.

Type of Tubes

While some bundles are straight tube whereas the other ones are “U”. U tubes as well as straight tubes are significant in their own way and are used for various reasons and industrial applications. Choosing whichever is needed usually depends but they both are most likely to come in handy. Recognizing these different kinds of a tube bundle is exceptionally easy as the straight ones are rather plain and quite in symmetry whereas the U tubes are literally in the shape of a U – which is very easy to spot. The more commonly used type of tubes is the U ones, since they are more easily available and beneficial in comparison with the straight ones.

Thickness of Tubes

The thickness of the tube is another factor that should be checked out before buying these bundles for any sort of uses, particularly for heat exchange. Certain standards of tube thickness have been set for people to see and decide which one they prefer more. The thickness of tubes actually makes the outer walls heavy, making the bundles much more solid and efficient in the long run. For all that these bundles have to offer, these should definitely be used for heat exchange and all the industrial uses related to it in general.
