Heat exchanger (also known as heat exchanger or heat exchange equipment) is used to make heat transfer from hot fluid to cold fluid to meet the specified process requirements of the device, is the convective heat transfer and heat transfer of an industrial application.
Heat exchanger classified by use
(1) Heater: used to heat the fluid to the required temperature, the heated fluid in the heating process does not occur phase change.
(2) Preheater: used to preheat the fluid to improve the efficiency of the whole set of process equipment.
(3)Superheater:Used to heat the saturated steam to a superheated state.
(4) Evaporator: Used to heat the fluid to vaporize it.
(5) Reboiler: used to heat the liquid has been condensed, so that its re-heating vaporization. Reboiler for the distillation process special equipment.
(6) Cooler: used to cool the fluid, so that it reaches the desired temperature.
(7) Condenser: used to cool the condensate saturated steam, so that it releases latent heat and condensation liquefaction.
