A heat exchanger is a device that is used to transfer thermal energy between two or more fluids, between a solid surface and a fluid, or between solid particulates and a fluid, at different temperatures and in thermal contact.
It provides a relatively large area of heat transfer for a given volume of the equipment. The construction also caters for easy cleaning and maintenance of equipment.
They are widely used in space heating, refrigeration, air conditioning, power plants, chemical plants, petrochemical plants, petroleum refineries, natural gas processing, sewage treatment. A classic example of heat exchanger is radiator coil in a car. It cools the engine coolant and preheated the incoming air.
The word heat exchanger really applies to all types of equipment in which heat is exchanged but is often used specifically to denote equipment in which heat is exchanged between two process streams.
