Description

Technical Field

[0001] The utility model relates to the technical field of condensers, in particular to a new energy vehicle refrigerator condenser. Background Art

[0002] The condenser is a component of the refrigeration system and a type of heat exchanger that can convert gas or vapor into liquid. During the operation of the condenser inside the refrigerator, the compressor compresses the working fluid from low-temperature and low-pressure gas into high-temperature and high-pressure gas, and then condenses it into medium-temperature and high-pressure liquid through the condenser. After throttling by the throttle valve, it becomes a low-temperature and low-pressure liquid. The low-temperature and low-pressure liquid working fluid is sent to the evaporator, where it absorbs heat and evaporates to become low-temperature and low-pressure steam, which is then sent to the compressor again to complete the refrigeration cycle. Since its advent, car refrigerators have been sought after by car owners. With the rapid development of the new energy vehicle market, car refrigerators are also rapidly iterating. The existing car refrigerators generate high heat when working, causing the temperature inside the car to be high. Simply extending the condenser tube and adding a heat sink to expand the heat dissipation area can no longer meet the needs of new energy car refrigerators for efficient heat dissipation.
