Description

[0001] The present invention relates to an integrated type water cooled condenser,

The present invention relates to an integrated water-cooled condenser, and more particularly, to an integrated water-cooled condenser in which a first plate on which a condenser and a subcooled portion are formed, a second plate on which a cooling water flow portion and an IHX refrigerant portion are formed are stacked alternately to form a heat exchange portion, Liquid condenser, a gas-liquid separator, and an internal heat exchanger (IHX) can be integrally formed, thereby reducing the size of the package, and simplifying the assembling and manufacturing processes.

In a refrigeration cycle of a general automotive air conditioner, an actual cooling function is generated by an evaporator in which a liquid heat exchange medium absorbs heat of vaporization heat in the vicinity and is vaporized. Wherein the gaseous heat exchange medium flowing into the compressor from the evaporator is compressed at a high temperature and a high pressure in the compressor, and the liquefied heat is discharged to the periphery in the process of liquefaction while the compressed gaseous heat exchange medium passes through the condenser, The medium again passes through the expansion valve to become a low-temperature and low-pressure humidified vapor state, and then flows into the evaporator again to be vaporized to form a cycle.

That is, the condenser is formed as a water-cooled type using air as a heat exchange medium for cooling the refrigerant and discharged through being condensed in a liquid state while the refrigerant in a gaseous state of high temperature and high pressure flows into the liquid state while discharging the liquid heat by heat exchange. .

The air-cooled condenser is configured to be heat-exchanged with the air flowing through the opening in the front face of the vehicle, and is fixed to the front side of the vehicle in which the bumper beam is formed for smooth heat exchange with the air.

However, since the air-cooled condenser is formed at the rear end of the bumper beam when a vehicle accident occurs, the impact force applied to the pedestrian can be increased and the construction of the heat exchanger is also highly likely to be damaged by impact. There is a problem that the premium calculation standard can be raised.

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

The water-cooled condenser includes a first fluid passage (21) and a second fluid passage (22) in which a plurality of plates (20) are laminated and through which the first heat exchange medium and the second heat exchange medium respectively flow, A second inlet pipe 41 and a second outlet pipe 42 through which the second heat exchange medium is introduced / discharged, a first outlet pipe 31 and a first outlet pipe 32, A first connection pipe 51 connecting the condensation region of the first fluid portion 21 and the gas-liquid separator 50, and a gas-liquid separator 50 separating the gas-liquid separator 50 and the gas- And a second connection pipe (52) connecting the subcooling region of the first fluid section (21).

The water-cooled condenser 10 is configured such that the first heat exchange medium flowing through the first inlet pipe 31 flows in the condensing region of the first flow section 21 and flows through the first connecting pipe 51 Liquid separator 50 and again flows through the second connecting pipe 52 in the subcooled region of the first flow portion 21 and then discharged through the first outlet pipe 32. [

At this time, the second heat exchange medium flows through the second inlet pipe (41) and flows into the second flow section (22) formed alternately with the first flow section (21), and the second heat exchange medium .

As a technology related to this, there is a domestic public patent No. 2012-0061534 (date June, 2012, name: water-cooled condenser).

On the other hand, the water-cooled condenser condenses the refrigerant using the cooling water of the electric radiator instead of the air. Since the cooling water temperature of the electric-field radiator is higher than the outdoor air temperature, the efficiency is low when used alone. Therefore, the IHX (Internal Heat Exchanger) is added to improve the above-mentioned problems.

In this way, when different types of heat exchangers are provided in the automotive air conditioner system, not only the piping construction is complicated to connect them, but the piping is additionally constructed and assembled, resulting in an increase in the production cost.

Also, if the piping layout becomes long and complicated, the refrigerant moves and acts on the side which is detrimental to the pressure drop, thereby deteriorating the performance and efficiency of the air conditioner system.
