Heat Exchangers

A heat exchanger is a device designed to efficiently transfer or "exchange" heat from one matter to another. When a fluid is used to transfer heat, the fluid could be a liquid, such as water or oil, or could be moving air. The most well known type of heat exchanger is a car radiator. In a radiator, a solution of water and ethylene glycol, also known as antifreeze, transfers heat from the engine to the radiator and then from the radiator to the ambient air flowing through it.

There are various types of heat exchangers.



Direct Expansion Evaporators		Single Pass Direct Expansion Evaporators



Flooded Evaporators		Shell and Tube Condensers
