A LOOK AT THE DIFFERENT TYPES OF HEAT EXCHANGERS

The Heat Exchanger is a device built for efficient transferring of fever energy from one fluid to other across a intent surface. in the heat exchanger design both the convection and conduction antecedent of fever transmit is used. There is no radiative transfer of heat rush between the exchanger also the environment unless the exchanger is uninsulated or its external surfaces are very boiling. The heat exchanger has wide use consequence engineering processes. The strikingly collective array of a heat exchanger is the radiator ascendancy a car. Here the hot fluid in the radiator is cooled by the air flow because of the radiator surface.

Some mismated examples of heat exchanger are preheaters, intercoolers, boilers, condensers, etc. that are used in the expertise plants. They are also used in refrigeration, air conditioning, chemical processing and power production.

Different types of fever Exchangers:

There are different types of heat exchangers. They can appear as classified according to its construction into;nation its following forms i.e. shell and cylinder heat exchanger and plate and build heat exchanger.

- Shell also tube heat exchanger: This is a typical heat exchanger. The blitz and tube heat exchanger is consisting of a series of finned tubes through which one of the fluids runs and the altered fluid which is to be fevered or cooled runs over the finned tubes.

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

The heat exchangers classified according to its uses are recuperative type, regenerative type also evaporative type.

- Recuperative type: In recuperative type heat exchanger the fever 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 same space containing a matrix of collateral which works alternatively as a sink or source for heat flow.

- Evaporative type: In evaporative type heat exchanger the fluid is evaporatively cooled in the same space as coolant such as the cooling sky-rocket.

- the recuperative type of heat exchanger again boundness be designed according to one of the following forms i.e. Parallel-flow, Counter-flow besides Cross-flow.

- Parallel-flow heat exchanger: clout this type of heat exchanger both the fluids exchanges heat by flowing in the akin direction through individual pipes.

- Counter-flow heat exchanger: In this type of heat exchanger the fluids exchanges heat by flowing juice the opposite direction through individual pipes.More futher :MODERN INTERIOR
