Heat exchanger development has a history of nearly a hundred years. It is widely used in many areas of national economy (such as food, pharmaceuticals, petrochemicals, Air conditioning, power, metallurgy, light industry, etc.). Heat exchanger is one of a wide range of unit equipment in chemical, petroleum, pharmaceutical and energy industries such applications.
Definition: Heat exchanger is the equipment to transfer part of the heat from the heat fluid to the cold fluid, also known as heat exchanger.
Heat exchangers are common equipments for refrigeration and air conditioning, HVAC, chemical industry, petroleum, power, food and many other industrial sectors. It occupies an important place in production. Heat exchanger is divided into condenser, evaporator, reheater, superheater and reboiler etc. according to the use of function. There are many types of heat exchangers, however, according to the principle of cold and hot fluid heat exchange,heat exchangers can basically be divided into three categories : partition, hybrid and regenerative. In the refrigeration and air conditioning, HVAC and other fields mainly involve hybrid heat exchanger and the wall heat exchanger, of which the most widely used heat exchanger.
