A Heat exchanger(H Exchanger) refers to a device built for effective heat transfer from one medium to another. In a heat exchanger, both the mediums are separated by a solid wall so that they never get in direct contact with each other. H exchangers are commonly used for large-scale industrial processes such as refrigeration, air conditioning, petrochemical plants, petroleum refineries, and natural gas processing.

A H Exchanger is in fact a device that facilitates efficient heat transfer from one fluid to another across a solid surface. The convection and conduction principle of heat transfer is mainly employed in the design and manufacturing of a H exchanger. One of the most common examples of a H exchanger is the radiator in a car where the hot fluid in the radiator gets cooled by the flow of air over the radiator surface. A few other examples of H exchangers are pre-heaters, intercoolers, boilers, condensers, etc. that are used in power plants. There are various types of H exchangers. H exchangers could be classified based on their design and construction into the following types i.e. shell and tube H exchanger and plate and frame H exchanger.

With scientific advancement, new technology has been employed in the manufacturing of heat exchangers and they have been put to a wide variety of industrial and commercial uses.

H exchangers such as sanitary heat exchangers used in product processing play a significant role in dairy processing facilities. They help a good deal in heating, cooling and pasteurizing dairy beverages and foods. Equipment manufacturers are always coming up with highly innovative methods and designs to enhance the overall efficiency of heat exchangers, save resources and customize them for various product types. New features have been incorporated for different types of H exchangers such as plate H exchangers, tubular heat and scraped-surface exchangers and for gasketed and welded units.

Quite recently, Radicon, a leading manufacturer of H exchangers in Southeast Asia, developed a new generation of efficient heat exchangers intended for heavy-duty applications. Headquartered in Bangkok, Thailand, Radicon is a well-known supplier of radiators, oil coolers and charge-air coolers.
