Description

Water cooled condenser of integrated type}

The present invention relates to an integrated water-cooled condenser, and more particularly, a heat exchange unit is formed by alternately stacking a plurality of first plates on which a condensation unit and a subcooling unit are formed and a plurality of second plates on which a cooling water flow unit and an IHX refrigerant unit are formed are formed, and the heat exchange By connecting the unit and the gas-liquid separation unit, a conventional water-cooled condenser, a gas-liquid separator, and an internal heat exchanger (IHX) can be integrally formed to reduce the package and simplify the assembly and manufacturing process.

In a refrigeration cycle of a typical vehicle air conditioner, an actual cooling action occurs by an evaporator in which a heat exchange medium in a liquid state absorbs heat equivalent 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 to a high temperature and high pressure in the compressor, and in the process of liquefying the compressed gaseous heat exchange medium passing through the condenser, liquefaction heat is released to the surroundings, and the liquefied heat exchanger As the medium passes through the expansion valve again, it becomes a low-temperature and low-pressure saturated vapor state, and then flows into the evaporator again and vaporizes to form a cycle.

That is, the condenser is formed by an air cooling type using air as a heat exchange medium for cooling the refrigerant and a water cooling type using liquid. It can be.

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

However, since the air-cooled condenser is formed at the rear end of the bumper beam in the event of a vehicle accident, the impact force applied to the pedestrian may increase, and the heat exchanger configuration is also highly likely to be damaged by impact. There is a problem that the insurance premium calculation standard may be raised.

As shown in FIG. 1 , the water-cooled condenser 10 may be a plate heat exchanger in which a plurality of plates 20 are stacked.

In the water-cooled condenser, a plurality of plates 20 are stacked to form a first flow part 21 and a second flow part 22 through which a first heat exchange medium and a second heat exchange medium respectively flow, and the first heat exchange medium The first inlet pipe 31 and the first outlet pipe 32 through which the inlet/outlet flows, the second inlet pipe 41 and the second outlet pipe 42 through which the second heat exchange medium flows in/out, and the first heat exchange medium A gas-liquid separator 50 for separating into a gas-phase heat exchange medium and a liquid-phase heat exchange medium, a first connection pipe 51 connecting the condensation area of the first flow part 21 and the gas-liquid separator 50, and the gas-liquid separator It is formed by including a second connection pipe 52 connecting the supercooled region of the first flow part 21 .

In the water-cooled condenser 10, the first heat exchange medium introduced through the first inlet pipe 31 flows in 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 through the supercooled region of the first flow part 21 again through the second connection pipe 52, and then is discharged through the first outlet pipe 32.

At this time, the second heat exchange medium is introduced through the second inlet pipe 41 and flows into the second flow part 22 formed by alternating with the first flow part 21, and the first heat exchange medium will cool down

As a related technology, there is Korean Patent Publication No. 2012-0061534 (published on 2012.06.13, name: water-cooled condenser).

On the other hand, the water-cooled condenser condenses the refrigerant by using the cooling water of the electric radiator instead of air. Since the temperature of the cooling water of the electric radiator is higher than the outside air temperature, the efficiency is low when used alone, and for this reason, the IHX with internal heat exchange function (Internal Heat Exchanger) is added to improve the above problems.

As such, when the vehicle air conditioner system is provided with different types of heat exchangers, not only the piping configuration is complicated to connect them, but also the piping must be additionally configured and assembled, resulting in an increase in production cost.

In addition, when the piping layout becomes long and complicated, the refrigerant moves and acts unfavorably on the pressure drop, so that the performance and efficiency of the vehicle air conditioner system inevitably deteriorates.
