A Search At The Various Sorts Of Heat Exchangers
The Heat Exchanger is a device built for efficient transferring of heat power from one particular fluid to an additional across a solid surface. In a heat exchanger style both the convection and conduction principle of heat transfer is employed. There is no radiative transfer of heat power between the exchanger and the surroundings unless the exchanger is uninsulated or its external surfaces are very hot. viessmann vitocell . The heat exchanger has wide use in engineering processes. The most common 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 more than the radiator surface.
Some other examples of heat exchanger are preheaters, intercoolers, boilers, condensers, etc. that are employed in the power plants. They are also employed in refrigeration, air conditioning, chemical processing and power production.
Diverse sorts of Heat Exchangers:
There are different sorts of heat exchangers. They can be classified according to its construction into the following kinds 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 particular 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 huge surface area. Here the flow is directed by means of the baffles. Lewes SEO Web Design oil fired hot water boilers .
The heat exchangers classified according to its utilizes are recuperative sort, regenerative variety and evaporative variety.
- Recuperative type: In recuperative type heat exchanger the heat from the fluids on either side of a dividing wall is exchanged.
- Regenerative kind: In regenerative variety heat exchanger the hot and cold fluids are allowed to occupy the same space containing a matrix of material that works alternatively as a sink or supply for heat flow.
- Evaporative sort: In evaporative type heat exchanger the fluid is evaporatively cooled in the same space as coolant such as a cooling tower.
- The recuperative type of heat exchanger once again can be designed 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 each the fluids exchanges heat by flowing in the same direction by way of person pipes. fantech bathroom fan .
- Counter-flow heat exchanger: In this type of heat exchanger the fluids exchanges heat by flowing in the opposite path by means of person pipes.
