Recuperative heat exchangers: In these heat exchangers, using a separating surface, hot and cold fluid are separated from each other and the transfer is done through the surface. It should be noted that the heat exchangers in the industry are more of this type.

Regenerative type heat exchanger: In this exchanger, the separating surface of cold and hot fluid is not fixed and Its parts are subject to movement with hot and cold fluid. The use of this type of heat exchanger is mostly done in laboratories and research environments.

Direct contact type heat exchangers: Cold and hot fluids in this contact heat exchanger are directly with each other; This means that there is no wall between them. In this converter, the streams are actually two immiscible liquids such as gas and liquid. One of the most important features of these converters is their high thermal efficiency. Cooling towers and Open Feed Water Heaters, which are used in steam power plants, are examples of these converters.
