The professional introduction of oil cooler is like this, the intelligent introduction of the crown,

Oil cooler is also called oil cooler. According to the principle of refrigeration system, low temperature and low pressure liquid refrigerant exchanges heat of oil with surrounding water in evaporator to absorb heat of oil and evaporate into low temperature and low pressure gas. During evaporation, the temperature of refrigerant remains unchanged. The low temperature and low pressure gas refrigerant enters the compressor, compressed by the compressor, is compressed into high temperature and high pressure gas, and then into condensation. In the condenser, heat is exchanged with the indoor medium. The part of heat in the high temperature and high pressure state is absorbed by the medium. The temperature of the medium rises. The heat of the refrigerant is released into the high temperature and high pressure liquid. The temperature of the condenser is unchanged. Then it enters the expansion valve for throttling. Throttling is a process of rapid cooling. The refrigerant becomes the liquid of low temperature and low pressure. After that, the refrigerant enters the evaporator again. The whole process of refrigeration system is realized by heat exchange and evaporation. This cycle is continuous and oil can be continuously refrigerated.
