[Walder] Working principle of oil cooler: According to the principle of the refrigeration system, the low-temperature and low-pressure liquid refrigerant exchanges heat with the surrounding water in the evaporator. The evaporator absorbs the heat of the oil and evaporates into a low-temperature and low-pressure gas state. The temperature of the refrigerant during the evaporation process Unchanged, the low-temperature and low-pressure gaseous refrigerant enters the compressor, is compressed by the compressor, and is compressed into a high-temperature and high-pressure gaseous state, and then enters the condenser, where it exchanges heat with the indoor medium in the condenser. The high-temperature and high-pressure gaseous part The heat is absorbed by the medium, the temperature of the medium rises, the refrigerant releases heat into a high-temperature and high-pressure liquid, the temperature of the condenser process remains unchanged, and then enters the expansion valve for throttling. Throttling is a process of rapid cooling, and the refrigerant becomes a low-temperature and low-pressure liquid. After this process, the refrigerant enters the evaporator for heat exchange and evaporation to realize the entire process of the refrigeration system. This cycle is continuous, and the oil can be continuously cooled.
