A heat exchanger is a device used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment.
FEATURES OF HEAT EXCHANGERS
Many modern heat exchangers, such as the plate heat exchanger, are very adaptable, which makes them suited for a wide variety of tasks.
●Cost and Maintenance
The fabrication costs of heat exchangers have fallen as technology has progressed.
●Wide industrial Applications
The heat exchanger as a piece of equipment is a simple model and therefore, has many applications in industry.
●Leakage and pressure drops
Leakage and pressure drops in the system are two key quality points of heat exchangers.

●Air coolers, intercoolers, oil coolers
Overview: What’s heat exchanger?
The basics of heat exchanger
Heat exchangers are a type of equipment used mainly to transfer heat from one medium to another efficiently. They are the basic technology behind many household items, including heating systems, refrigerators and air conditioners. There are many different types of heat exchangers, each of which serving different purposes for different applications.
How does heat exchanger work
A heat exchanger is a device used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. 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, which 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.
