Description

Water cooled condenser

The present invention relates to a water-cooled condenser, and in more detail, plates are stacked to form a condensation area and a subcooling area, and a gas-liquid separator is disposed between the condensation area and the subcooling area, and the refrigerant and cooling water are placed inside the bracket that fixes the gas-liquid separator. It relates to an integrated water-cooled condenser in which the packaging and assembly process is simplified by forming a connecting passage.

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.

However, in the event of a vehicle accident, the air-cooled condenser is formed at the rear end of the bumper beam, so the impact force applied to pedestrians may increase, and the heat exchanger configuration also has a high risk of being damaged by impact, and depending on the expected repair costs accordingly, There is a problem that the insurance premium calculation standard may increase.

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.

However, as described above, the water-cooled condenser accommodating the gas-liquid separator is connected to a separate gas-liquid separator tank, and the structure of connecting the condensation area and the subcooling area with a conduit requires many additional parts for connection and takes up a lot of space. Therefore, it has the disadvantage of being unreasonable in terms of packaging and component composition.

A baffle 170 is formed in which at least one of the refrigerant inflow and outflow holes 151, refrigerant flow holes 152, coolant inflow and outflow holes 153, and coolant flow holes 154 is sealed,
A water-cooled condenser, characterized in that the flow path of the refrigerant or cooling water is adjusted.
According to clause 9,
The water-cooled condenser (1) is
When either the refrigerant inlet/outlet hole 151 or the refrigerant flow hole 152 is sealed and two or more refrigerant passages are formed within the condensation area 200 or the subcooling area 300, a refrigerant flow path assigned to each pass is A water-cooled condenser, characterized in that the ratio of the refrigerant flow portion (140) is the same.
