Heat Exchangers

A heat exchanger is a system that transfers heat between two or more fluids. Both cooling and heating processes units uses heat exchangers. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. The widely used area of HE; space heating, refrigeration, air conditioning. Power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. Therefore, the classic example of a heat exchanger is found in an internal combustion engine. In which a circulating fluid known as engine coolant flows through radiator coils. And air flows past the coils, which cools the coolant and heats the incoming air. Another example is the heat sink. The heat sink is a passive heat exchanger that transfers the heat generated by an electronic. Or a mechanical device to a fluid medium, often air or a liquid coolant.
