A heat exchanger is a system 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
Shell and tube heat exchangers have a simple design.

relatively low purchase and maintenance costs.
They also have a very high heat transfer rate although they require more space than a plate heat exchanger of similar thermal exchange capacity·Shell and tube heat exchangers have a simple design.
