Pacific Automotive Network 1, different forms of work: the condenser is to give the medium cooling liquefaction, external exothermic; evaporator is the medium heat absorption gasification, absorption of heat from the outside world. 2, the thickness is different: the smaller the evaporator, the thicker the tube wall, at the same time, the evaporator is higher than the thickness of the condenser.
The condenser for the refrigeration system, belongs to a heat exchanger, the gas or vapor into a liquid, the heat in the tube, in a very fast way, to the air near the tube. Condenser work process is an exothermic process, so the condenser temperature are higher.
The evaporator is also a very important part of refrigeration, low temperature condensed liquid through the evaporator, and the outside air for heat exchange, gasification and heat absorption, to achieve the effect of refrigeration.
The condenser and evaporator are heat exchangers. The so-called heat exchange, that is, there are two or more than two different temperatures between the fluid mutual heat transfer equipment, so also known as heat exchange equipment. Therefore, although the structure of the condenser and evaporator form a variety of different but the principle of work is the same, are through the refrigerant and flow through the surface of the container of the external medium of heat transfer equipment, that is, are a heat exchanger. In the factors affecting heat transfer condenser and evaporator is also the same, its heat transfer with the heat transfer area, heat transfer temperature difference, heat transfer coefficient have tube relationship.
