The Heat Exchanger is a device built for efficient transferring of heat energy from one fluid to another across a solid surface. In a heat exchanger design both the convection and conduction principle of heat transfer is used. There is no radiative transfer of heat energy between the exchanger and the environment unless the exchanger is uninsulated or its external surfaces are very hot. The heat exchanger has wide use in engineering processes. The most common example of a heat exchanger is the radiator in a car. Here the hot fluid in the radiator is cooled by the air flow over the radiator surface.
Some other examples of heat exchanger are preheaters, intercoolers, boilers, condensers, etc. that are used in the power plants. They are also used in refrigeration, air conditioning, chemical processing and power production.
Different types of Heat Exchangers:
There are different types of heat exchangers. They can be classified according to its construction into the following types i.e. shell and tube heat exchanger and plate and frame heat exchanger.
– Shell and tube heat exchanger: This is a typical heat exchanger. The shell and tube heat...
