The Heat Exchanger is a device constructed for productive transferring of heat energy from 1 fluid to yet another across a strong surface. In a heat exchanger style each the convection and conduction principle of heat transfer is utilized. There is no radiative transfer of heat energy between the exchanger and the atmosphere unless the exchanger is uninsulated or its external surfaces are really hot. The heat exchanger has wide use in engineering processes. The most prevalent instance of a heat exchanger is the radiator in a vehicle. Right 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, and so on. that are utilized in the power plants. They are also used in refrigeration, air conditioning, chemical processing and power production.

Diverse sorts of Heat Exchangers:

There are various types of heat exchangers. They can be classified according to its construction into the following varieties i.e. shell and tube heat exchanger and plate and frame heat exchanger.

- Shell and tube heat exchanger: This is a standard heat exchanger. The shell and tube heat exchanger is consisting of a series of finned tubes via which one of the fluids runs and the other fluid which is to be heated or cooled runs over the finned tubes.

- Plate and frame heat exchanger: In a plate and frame heat exchanger, the fluids are separated by plates with a large surface location. Here the flow is directed through the baffles.

The heat exchangers classified according to its makes use of are recuperative type, regenerative kind and evaporative sort.

- Recuperative sort: In recuperative type heat exchanger the heat from the fluids on either side of a dividing wall is exchanged.

- Regenerative sort: In regenerative variety heat exchanger the hot and cold fluids are allowed to occupy the same space containing a matrix of material that performs alternatively as a sink or supply for heat flow.

- Evaporative sort: In evaporative kind heat exchanger the fluid is evaporatively cooled in the very same space as coolant such as a cooling tower.

- The recuperative sort of heat exchanger once again can be designed according to one particular of the following sorts i.e. Parallel-flow, Counter-flow and Cross-flow.

- Parallel-flow heat exchanger: In this sort of heat exchanger each the fluids exchanges heat by flowing in the very same direction by way of individual pipes.

- Counter-flow heat exchanger: In this variety of heat exchanger the fluids exchanges heat by flowing in the opposite direction through person pipes. SeaverGormley33 — ???????????? ???????? ?????
