The present invention relates to a condenser, and more particularly, to an inlet pipe and an outlet pipe are formed by being inserted into the header tank can be miniaturized and improved assemblability.

A heat exchanger is a device that absorbs heat from one side and releases heat to the other between two environments with a difference in temperature. If a heat exchanger absorbs heat from the room and emits it to the outside, it is a cooling system. In this case it will act as a heating system. Basically, the heat exchanger is composed of an evaporator that absorbs heat from the surroundings, a compressor for compressing the heat exchange medium, a condenser that releases heat to the surroundings, and an expansion valve for expanding the heat exchange medium.

In the cooling device, an actual cooling action is caused by an evaporator in which the heat exchange medium in the liquid state absorbs the amount of heat as vaporized heat from the surroundings and vaporizes. The heat exchange medium in the gas state flowing from the evaporator to the compressor is compressed at high temperature and high pressure in the compressor, and liquefied heat is released to the surroundings in the process of liquefying the compressed gas heat exchange medium through the condenser. As the medium passes through the expansion valve again, it becomes a low-temperature and low-pressure wetted vapor state, and then flows into the evaporator to evaporate to form a cycle.

As described above, in the condenser, a heat exchange medium in a gaseous state of high temperature and high pressure flows in, is discharged after being condensed in a liquid state while releasing liquefied heat by heat exchange, and is shown in FIG.

The condenser 180 shown in FIG. 1 includes a pair of header tanks 110 formed to be spaced apart from each other at a predetermined distance; An inlet pipe 120 and an outlet pipe 130 formed in the header tank 110 to allow the heat exchange medium to flow in or out; A baffle 140 provided inside the header tank 110 to adjust a flow of the heat exchange medium; A plurality of tubes 150 provided between the header tanks 110; A plurality of fins 160 stacked between the tubes 150; And a gas-liquid separator 170 provided on one side of the header tank 110 to separate the gas-phase heat exchange medium from the liquid-phase heat exchange medium. It is designed to induce subcooling by collecting only the liquid refrigerant in the gas-liquid separator.

The condenser as shown in FIG. 1 has the advantage of being able to further lower the enthalpy of the heat exchange medium by the supercooling to increase the cooling efficiency.

However, the condenser as shown in FIG. 1 protrudes a certain region to the outside of the condenser header tank because the inlet pipe and the outlet pipe for introducing the heat exchange medium are formed on one side of the header tank and fixed by a flange. To form a defined area.
