Heat exchanger is an important and indispensable device of refrigeration equipment, heat transfer effect of heat exchanger directly affects the weight, volume, the characteristics of running machine and economy.

Condenser is refrigeration equipment gives out heat to the cooling system of the heat exchange device. Refrigerant in the condenser heat release includes two parts: 1. Absorbed in the evaporator heat object to be cooled., 2. the consumption of the compressor mechanical work into heat while refrigerant vapor in refrigeration compressor is compressed,

Condenser according to the cooling medium and cooling mode, can be divided into three types:

1）water cooled condenser

2）air-cooled condenser

3）evaporative condenser
