The Heat Exchanger is a device built for efficient transferring of heat power from 1 fluid to another across a solid surface. In a heat exchanger style each the convection and conduction principle of heat transfer is utilised. There is no radiative transfer of heat energy between the exchanger and the environment unless the exchanger is uninsulated or its external surfaces are quite hot. The heat exchanger has wide use in engineering processes. The most common instance of a heat exchanger is the radiator in a automobile. 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 utilised in the energy plants. They are also employed in refrigeration, air conditioning, chemical processing and power production.
Diverse sorts of Heat Exchangers:
There are various kinds 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 exchanger is consisting of a series of finned tubes by way of which a single 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 area. Here the flow is directed by way of the baffles.
The heat exchangers classified according to its utilizes are recuperative sort, regenerative kind and evaporative kind.
- Recuperative type: In recuperative sort heat exchanger the heat from the fluids on either side of a dividing wall is exchanged.
- Regenerative type: In regenerative type heat exchanger the hot and cold fluids are allowed to occupy the identical space containing a matrix of material that functions alternatively as a sink or supply for heat flow.
- Evaporative type: In evaporative sort heat exchanger the fluid is evaporatively cooled in the identical space as coolant such as a cooling tower.
- The recuperative sort of heat exchanger again can be made according to a single of the following sorts i.e. Parallel-flow, Counter-flow and Cross-flow.
- Parallel-flow heat exchanger: In this type of heat exchanger both the fluids exchanges heat by flowing in the exact same direction through person pipes.
- Counter-flow heat exchanger: In this kind of heat exchanger the fluids exchanges heat by flowing in the opposite direction via person pipes. environmental pest control services
