Some Basic Facts about Heat Exchangers

When heat requires to be transferred from one fluid to another one, there is no better device to do this task than the heat exchanger. Another task of this device is not to let the two aforementioned fluids to come in contact with each other.

The most basic classification of heat exchangers goes like this: the air cooled heat exchanger, the shell and tube heat exchanger and finally the plate heat exchanger.

The item that divides the two fluids and prevents them from coming in contact with each other is a conductive metal wall. On each side of this wall there are 2 flowing liquids: one is a hot and one is cool. The purpose is to convey the heat from the hot solution to the cool solution. The larger the surface area of the heat exchanger is, the faster the transfer of heat will be produced. The whole process is possible because of the properties of thermal energy, specifically the fact that it can only flow from a hot are to a cooler one. An important thing to note is that you must always do proper maintenance and regular heat exchanger cleaning.

If you are confused and think you have never heard about the heat exchanger before, you will be astounded to find out that you have seen it in action before. Example: your own car has a heat exchanger. It is called a radiator. Air conditioners, swimming pools and refrigerators also use this principle.

The most important materials out of which heat exchangers are manufactured include: steel, aluminum, bronze, titanium and copper. The applications for this device are almost unlimited, and this is the reason why it is widely used in many industries, where its great importance in acknowledged.
