A heat exchanger is a device built for efficient heat transfer from one medium to another. The media may be separated by a solid wall, so that they never mix, or they may be in direct contact ^[1]. They are widely used in space heating, refrigeration, air conditioning, power plants, chemical plants, petrochemical plants, petroleum refineries, natural gas processing, and sewage treatment. One common example of a heat exchanger is the radiator in a car, in which the heat source, being a hot engine-cooling fluid, water, transfers heat to air flowing through the radiator (i.e. the heat transfer medium).

Types of Heat Exchangers:

Air source heat pumps 

Baffle

Concentric tube heat exchanger

Radiator

Recuperator

Regenerative heat exchanger

Shell and tube heat exchanger

Solar air heater

Solar hot water heater

Solar wall

Thermal wheel

Waste Heat Recovery Unit
