Description

Condenser {A CONDENSER}

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 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, 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.

9 is a first heat exchange medium flow schematic diagram of a condenser 1000 according to the present invention. The first heat exchange medium passes through the first inlet portion 210 and passes through the air cooling region where the air is cooled through some tubes 300 and then flows through the first body 510 of the gas-liquid separator 500 Passes through the gas-liquid separation zone A2 where the vapor-phase first heat exchange medium and the liquid-phase first heat exchange medium are separated, passes through the supercooled zone A3 where only the liquid first heat exchange medium is again supercooled through the remaining tubes 300 , And is discharged through the first outlet portion (220). At this time, the size of the air-cooling area and the subcooling area A3 and the flow of the first heat exchange medium in the inside of the pair of header tanks 100 are determined by the formation position of the baffle 101 blocking the longitudinal flow, And the like. 9 shows an example in which two baffles 101 are provided in the left header tank 100 and two baffles 101 are provided in the right header tank 100. In the condenser 1000, The position of the first inlet portion 210 and the first outlet portion 220, the number of the baffles 101, and the number of the baffles 101 The position, etc. can be adjusted in various ways.

10 is a second heat exchange medium flow schematic diagram of a condenser 1000 according to the present invention. The second heat exchange medium flows through the second inlet portion 531 and rotates along a second heat exchange medium flow path formed between the groove portion 513a of the first body 510 and the second body 520, And then discharged through the second outlet portion 532. [ 10, the second inlet portion 531 is located on the upper side of the drawing, the second outlet portion 532 is located on the lower side of the drawing, and the second heat exchange medium is located on the outer peripheral surface of the first body 510 And moves to the lower side while rotating along the axis, and may have the opposite flow including this.

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.

That is, in the condenser 1000 of the present invention, the gas-liquid separator 500 includes the first body 510 and the second body 520, and the first heat exchange medium additionally performs heat exchange with the second heat exchange medium There is an advantage that the subcooling degree can be further increased and the entire heat exchanging performance can be improved and the size can be reduced.
