Heat exchanger
Heat exchanger (English translation: heat exchanger), parts of the thermal fluid heat transfer to the cold fluid equipment, also called heat exchanger. Heat exchangers are common equipments in chemical, petroleum, power, food and many other industrial sectors, which are important in production. Heat exchanger can be used as heater, cooler, condenser, evaporator and reboiler in chemical production. There are many kinds of heat exchangers, but according to the principles and methods of heat exchange of cold and hot fluid, there are basically three types of heat exchangers: the wall, the mixed and the regenerative. In the three types of heat exchangers, the application of the wall heat exchanger is the most.
