What is an oil cooler

The oil cooler is born and used according to the principle of the refrigeration system. For example, in some cases of low temperature and low pressure, the refrigerant inside will work with the surrounding water in the evaporator, that is, the heat exchange with the circulating water , Keep the low temperature and low pressure state, then put the state of the gas in the compressor, and then work through the heat exchange. In this process, the oil is used to make low temperature and low pressure gas, and it is always recycled. Therefore, the oil cooler is also called the oil cooler
