Description

Condenser {A CONDENSER}

The present invention relates to a condenser, and more particularly, to provide a condenser having a gas-liquid separator capable of significantly reducing the possibility of leakage as the diaphragm is forcedly inserted into the case and assembled integrally, thereby accurately separating the liquid refrigerant.

A heat exchanger is a device that absorbs heat from one side to the other and dissipates heat to the other side. It is a cooling system that absorbs heat from the room and emits it to the outside. It will act as a heating system. Basically, the heat exchanger is composed of an evaporator for absorbing heat from the surroundings, a compressor for compressing the heat exchange medium, a condenser for releasing heat to the surroundings, and an expansion valve for expanding the heat exchange medium.

In the cooling apparatus, an actual cooling action is caused by an evaporator in which a liquid heat exchange medium absorbs heat as much as the heat of vaporization 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.

As described above, in the condenser, refrigerant in a gaseous state at a high temperature and a high pressure flows into the condenser, and is condensed into a liquid state and discharged after being discharged by heat exchange. The conventional condenser is shown in FIG. 1 and FIG.

The condenser shown in FIGS. 1 and 2 includes a first header tank 10 and a second header tank 20, which are spaced apart from each other by a predetermined distance. An inlet pipe (40) and an outlet pipe (50) provided in the second header tank (20) to allow the refrigerant to flow in or out; A baffle 30 provided in the first header tank 10 and the second header tank 20 to control the flow of the refrigerant; A plurality of tubes (60) having both ends fixed to the first header tank (10) and the second header tank (20) to form a refrigerant channel; A plurality of fins (70) stacked between the tubes (60); And a gas-liquid separator (80) provided at one side of the first header tank (10) and separating the gaseous refrigerant from the liquid refrigerant. The gas-liquid separator (80) As shown in Fig.

1 and 2, the gaseous refrigerant compressed by the compressor at high temperature and high pressure flows into the inlet pipe of the first header tank, and the gaseous refrigerant introduced into the second header Moved to the tank. At this time, since condensation occurs in the condenser, the gaseous phase and the liquid phase are mixed, so that the gaseous refrigerant is moved to the upper side and the liquid refrigerant is moved to the lower side.

The liquid refrigerant collected in the lower portion of the gas-liquid separator through the upper and lower regions along the flow path formed by the baffle collects most of the liquid refrigerant. The liquid refrigerant passes through the subcooled region and a supercooling angle is generated. So that the cooling efficiency can be increased.

3 is a ph diagram of the condenser. FIG. 3 (a) shows a Ph diagram of the condenser in which the supercooled region is not formed, and FIG. 3 (b) The ph diagram of the condenser as shown above is shown. As shown in FIG. 3, the conventional condenser has the advantage of being able to further reduce the enthalpy of the refrigerant due to the occurrence of the supercooling, thereby increasing the cooling efficiency. However, the temperature of the internal refrigerant in the supercooled region is directly affected by the air temperature and the air flow rate. However, in many cases, an intercooler is generally provided in the lower part of the front side of the condenser, so that the temperature of the air flowing into the supercooled area is increased and the air volume is lowered, which may cause the supercooling to be lowered. This causes deterioration of the overall air conditioner cooling performance.

The condenser 1000 of the present invention includes a header tank 100, an inlet portion 210 and an outlet portion 220, a tube 300, a fin 400, and a gas-liquid separator 500.

The header tank 100 includes a pair of baffles 101 spaced apart from each other by a predetermined distance in the vehicle width direction, and a baffle 101 for blocking refrigerant movement in a vehicle height direction. At this time, the header tank 100 may be formed by a combination of a header and a tank. In addition, the header tank 100 is provided with an inlet portion 210 through which refrigerant flows into the header tank 100 and an outlet portion 220 through which the refrigerant flows.

The tubes 300 are fixed to the pair of header tanks 100 in parallel to each other in the height direction of the vehicle to form a coolant flow passage, and a pin 400 is interposed between the tubes 300. In addition, in the tube 300, the refrigerant is condensed in a certain region on the upper side in the vehicle height direction, and the remaining region on the lower side is supercooled in the refrigerant. That is, in the condenser 1000 of the present invention, the supercooled region A3 in which the condensation region A1 for condensing the refrigerant is located on the lower side in the vehicle height direction and the liquid refrigerant separated through the gas-liquid separator 500 is supercooled And is located on the upper side in the vehicle height direction. Accordingly, the condenser 1000 of the present invention has an advantage that the overall cooling efficiency can be improved because the supercooled region A3 is formed on the upper side to prevent the heat exchange efficiency from being lowered by increasing the temperature of the outside air by a separate heat exchanger have. Particularly, in the condenser 1000 of the present invention, when the intercooler is provided in the lower part of the front side of the condenser 1000, since the outside air flowing into the supercooled area A3 passes through the intercooler, the temperature increases, There is an advantage that the problem can be prevented.

The gas-liquid separator 500 is provided at one side of the header tank 100 to separate the gaseous refrigerant and the liquid-phase refrigerant, and discharges only the liquid-phase refrigerant to the subcooled region A3.
