Description
The present invention relates to a condenser, and more particularly, to a condenser capable of further heat-exchanging a first heat exchange medium with a second heat exchange medium by using a gas-liquid separator including a first body and a second body, .
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
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, even if the subcooled region is formed, the temperature of the internal refrigerant can not be lowered below the temperature of the air side, so there is a limit in reducing enthalpy. That is, there is a problem that there is a limitation in increasing the cooling efficiency since the supercooling degree is limited.
In addition, in order to satisfy user's various tastes in the world, the condenser is required to be miniaturized and improved in performance in accordance with the current technical trend of gradually lighter, smaller, and higher performance components in the vehicle.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a gas-liquid separator, which includes a first body and a second body, wherein the first heat exchange medium further includes a second heat exchange medium The present invention relates to a condenser capable of increasing the degree of supercooling and improving the overall heat exchange performance by heat exchange.

As the second heat exchange medium, various media for cooling the first heat exchange medium may be used. For example, a low temperature refrigerant passing through an evaporator may be used. Since the low-temperature refrigerant passing through the evaporator has a temperature lower than that of the first heat exchange medium that has passed through the condensing region A1, the first heat exchange medium can be effectively cooled and moved to the supercooled region A3 in a cooled state The degree of supercooling can be increased to improve the heat exchange efficiency of the entire first heat exchange medium.
