There are some terms worth noting at the start of this article. They are there to give a brief touch on what will be covered in this article. They are hot water storage tanks, IHT, in line heaters, inter coolers, ITT Conoflow, ITT Neo Dyn, ITT standard, Munters, Neo Dyn, over the side heaters, plate and frame heat exchanger, portable chillers, and more.

There are some statistics worth noting at the start of this article as well. The statistics are there to provide a more detailed view of the topic that is being covered and the specific parts of that topic. They are:

  • When a heat exchanger’s fluids pass each other more than once, it is called a multi-pass heat exchanger.
  • Heat Exchangers are used to transfer heat between two things, between a solid surface at different temperatures and in thermal contact.
  • The very close proximity of fluids creates an exceptionally high heat transfer rate and allows close temperature approaches.
  • For the heat transfer to occur two fluids must be at different temperatures and they must come to thermal contact.
  • In parallel flow heat exchangers, the fluids flow in same direction.

Physics dictates that when two objects are close together, they will exhibit certain properties. If they are rubbing close together, this is considered to be the scientific term friction between those two objects. If they have electromagnetic properties, the transfer of those electrodes would be described at transference.

There is another situation that is important, especially when in chemistry and other subjects that involve liquid. That is, the mechanism of action when two liquids or objects close to one another are pressed together, and if they have a different temperature. This issue, with the different temperature, is important.

Physics states that when two objects are pressed next to each with the same temperature that their will be an energy transfer between the two. This energy transfer results in a cooling of one temperature and a warming of the other temperature. This is called changing the temperature.

The two objects, which were once apart in temperature, will eventually become the same temperature, according to this equilibrium issue. The hotter temperature will become cooler and the cooler temperature will become warmer. There are many examples of this in every day society.

A glass of water might be warm to the touch. When someone pours a certain amount of cold water in it, the glass becomes colder and the water becomes warmer. If someone with a cold hand touches someone who is warm, that hand becomes warmer and the person becomes colder. If a hot bowl gets some ice cream, the hot bowl will cool and the ice cream will warm.

If someone needs to “warm up” by putting on mittens, the mittens will become colder and the hands will become warmer. There are many situations in which this principle is explained in nature. There are many important instances of it in chemical laboratories and other scientific fields.

Within science and engineering, there are objects called heat exchangers, which are known to transfer heat from one object to another. They are important in numerous engineering applications, as heat transfer is not a simple matter of putting two objects close to one another.

In the case of engineering and the case of science, heat needs to be transferred quickly between objects in order for this to have an effect. There are heat exhangers in vehicles, in machines, in products, in chemical sets, in complex chemistry cases, in MRI machines, in X-Ray machines and more.

There may be other uses for it as well. Heat exchangers can happen in numerous situations and applications. Heat exchangers rely on that simple principle, that two objects close together will change temperature if pressed onto one another, while applying it in numerous ways when it comes to machines.

There are many important points about heat exchangers that have been mentioned in the statistics above. The important point is that they rely on basic physics to be able to apply processes to machines, chemical sets, and more. They are available for online at purchase and can do well.

Heat exchangers have positive qualities and negative qualities. The engineering of the heat exchangers makes the difference between good machines and bad machines. It’s important to note that the physics stays the same.
