The Heat money handler could be a device designed for economical transferring of warmth energy from one fluid to a different across a solid surface. in a very device style each the convection and conductivity principle of warmth transfer is employed. there's no radiative transfer of warmth energy between the money handler and also the surroundings unless the money handler is uninsulated or its external surfaces area unit extremely popular. the warmth money handler has wide use in engineering processes. the foremost common example of a device is that the radiator in a very automotive. Here the new fluid within the radiator is cooled by the air flow over the radiator surface.
Some other samples of device area unit preheaters, intercoolers, boilers, condensers, etc. that area unit utilized in the facility plants. they're additionally utilized in refrigeration, air-con, chemical process and power production.
Different types of warmth Exchangers:
There area unit differing types of warmth exchangers. they will be classified per its construction into the subsequent sorts i.e. shell and tube device and plate and frame device.
- Shell and tube {heat money handler|device}: this can be a typical heat exchanger. The shell and tube device is consisting of a series of finned tubes through that one in all the fluids runs and also the alternative fluid that is to be heated or cooled runs over the finned tubes.
- Plate and frame {heat money handler|device}: in a very plate and frame heat exchanger, the fluids area unit separated by plates with an oversized expanse. Here the flow is directed through the baffles.
The heat exchangers classified per its uses area unit restorative kind, regenerative kind and physical change kind.
- restorative kind: In restorative type device the warmth from the fluids on either aspect of a dividing wall is changed.
- Regenerative kind: In regenerative type device the new and cold fluids area unit allowed to occupy identical house containing a matrix of fabric that works as an alternative as a sink or supply for warmth flow.
- physical change kind: In physical change type device the fluid is evaporatively cooled within the same house as fluid like a cooling system.
- The restorative sort of device once more may be designed per one in all the subsequent sorts i.e. Parallel-flow, Counter-flow and Cross-flow.
- Parallel-flow {heat money handler|device}: during this sort of heat exchanger each the fluids exchanges heat by flowing within the same direction through individual pipes.
- Counter-flow {heat money handler|device}: during this sort of heat exchanger the fluids exchanges heat by flowing within the other way through individual pipes.
