In the refrigeration cycle of a typical vehicle air conditioner, the actual cooling effect occurs through the evaporator, where the liquid heat exchange medium absorbs heat equal to the heat of vaporization from the surroundings and is vaporized. The gaseous heat exchange medium flowing into the compressor from the evaporator is compressed at high temperature and pressure in the compressor, and liquefaction heat is released to the surroundings in the process of liquefying the compressed gaseous heat exchange medium as it passes through the condenser. As the medium passes through the expansion valve again, it becomes wet-saturated vapor at low temperature and low pressure, and then flows back into the evaporator and vaporizes, completing a cycle.

That is, the condenser is a gaseous refrigerant of high temperature and pressure flowing in, condensing into a liquid state while releasing liquefaction heat through heat exchange, and then being discharged. It is formed of an air-cooled type using air as a heat exchange medium to cool the refrigerant, or a water-cooled type using liquid. It can be.

The air-cooled condenser is a component that exchanges heat with air flowing in through an opening in the front of the vehicle, and is fixed to the front of the vehicle where the bumper beam is formed for smooth heat exchange with the air.

In the water-cooled condenser 10, the first heat exchange medium introduced through the first inlet pipe 31 flows through the condensation area of the first flow part 21, and the first heat exchange medium flows through the first connection pipe 51. It moves to the gas-liquid separator 50, flows again through the subcooled region of the first flow part 21 through the second connection pipe 52, and is then discharged through the first outlet pipe 32.

At this time, the second heat exchange medium flows in through the second inlet pipe 41 and flows into the second flow part 22 formed alternately with the first flow part 21. is cooled.

Therefore, it has the disadvantage of being unreasonable in terms of packaging and component composition.
