Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an oil cooler. Background technique [0002] Oil cooler is also called oil cooler. According to the principle of refrigeration system, the low-temperature and low-pressure liquid refrigerant exchanges heat with the surrounding oil 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 remains unchanged during the evaporation process , The low-temperature and low-pressure gaseous refrigerant enters the compressor, is compressed by the compressor, is compressed into a high-temperature and high-pressure gaseous state, and then enters the condenser, where it exchanges heat with the indoor medium, and part of the heat of the high-temperature and high-pressure gaseous state is absorbed The medium absorbs, the temperature of the medium rises, the refrigerant releas...

AI Technical Summary

Problems solved by technology

[0003] In traditional oil coolers, the heat exchange between hot oil and refrigerant is carried out in the iron evaporator, which is installed outside the iron oil tank. After the hot oil is cooled in the iron evaporator, it flows back through the pipeline For iron oil tanks, this setting has the following disadvantages: 1. The refrigerant pipes and cold oil pipes on the iron evaporator are prone to condensation and condensed water, which will cause rust at the interface between the pipes and the iron evaporator for a long time; 2. 1. The heat insulation performance of the iron evaporator is poor, resulting in slow cooling speed; 3. When the cold oil flows back from the iron evaporator to the fuel tank, it will definitely absorb the heat from the outside, and the heat insulation performance of the iron fuel tank is poor, resulting in oil cooling. The cooling effect of the machine is poor and the energy consumption is high; 4. It is necessary to weld the pipe on the iron evaporator during processing, and the processing steps are cumbersome
