이를 첨부도면을 참조하여 보다 상세하게 설명하면 다음과 같다.This will be described in more detail with reference to the accompanying drawings.

첨부도면 2는 본 발명에 따른 에어 컨디션 장치를 나타내는 개략도이고, 첨부도면 3은 본 발명에 따른 이중중공관을 나타내는 단면도로서, 도면부호 10은 컴프레셔를, 20은 콘덴서를, 100은 라디에이터를 각각 나타낸다.FIG. 2 is a schematic view showing an air conditioner according to the present invention, and FIG. 3 is a cross-sectional view showing a double hollow tube according to the present invention, wherein 10 is a compressor, 20 is a condenser, and 100 is a radiator. .

본 발명은 상기 컴프레셔(10)에서 압축된 냉매를 콘덴서(20)에 공급하는 연결관(12)에 세방향밸브(11)를 설치하여, 일정한 조건에서 냉매가 라디에이터(100)의 상부탱크(110)를 거쳐서 콘덴서(20)에 공급되게 함으로써. 초기 시동시 냉각수를 이용하여 냉매를 냉각시켜서 냉각효율을 향상시킬 수 있게 한 것이다.According to the present invention, the three-way valve 11 is installed in the connecting pipe 12 for supplying the refrigerant compressed by the compressor 10 to the condenser 20, so that the refrigerant is in the upper tank 110 of the radiator 100 under a certain condition. By supplying to the condenser 20 via In the initial start-up, the cooling water is used to cool the refrigerant to improve the cooling efficiency.

여기서, 상기 상부탱크(110)에는 서로 다른 직경을 갖는 이중중공관(30)이 일정한 간격을 유지할 수 있도록 설치되어 있으며, 안쪽중공관(30a)에는 상기 라디에이터(100)를 통과하는 냉각수가 흐르게 설치되며, 바깥쪽중공관(30b)에는 상기 컴프레셔(10)로부터 유출되는 냉매가 선택적으로 흐르게 된다.Here, the double tank 30 having a different diameter is installed in the upper tank 110 to maintain a constant interval, the inner hollow pipe (30a) is installed so that the cooling water passing through the radiator 100 flows The refrigerant flowing out of the compressor 10 selectively flows to the outer hollow pipe 30b.

특히, 상기 바깥쪽중공관(30b)에는 외주면에 방열핀(31)을 형성하여 냉각효과를 더욱 높일 수 있게 하는 것이 바람직하다.In particular, it is preferable to form a heat radiation fin 31 on the outer circumferential surface of the outer hollow tube (30b) to further increase the cooling effect.

이와 같이 바깥쪽 중공관(30b)에 선택적으로 냉매를 공급하는 것은 세방향 밸브(11)에 의하여 이루어지게 되며, 이 세방향 밸브(11)는 시동 초기에 냉매와 냉각수의 온도를 비교하여 냉매의 유동방향을 결정하게 된다.In this way, the supply of the refrigerant selectively to the outer hollow tube (30b) is made by the three-way valve (11), the three-way valve (11) by comparing the temperature of the refrigerant and the coolant at the beginning of the refrigerant The direction of flow is determined.

즉, 상기 세방향 밸브(11)는 유입구쪽을 컴프레서(10)에 연관하고 2개의 유출구쪽에는 콘덴서(20)와 라디에이터(100)에 각각 연관하여서, 일방적인 조건하에 서는 냉매가 컴프레셔(10)로부터 직접 컨덴서(20)로 공급하게 하고, 냉매가 냉각수의 온도에 비해 일정치 이상 높게 되면 라디에이터(100)를 통과하도록 한 것이다.That is, the three-way valve 11 is associated with the compressor 10 in the inlet side and the condenser 20 and the radiator 100 at the two outlet sides, respectively, so that the refrigerant is compressed under the one-way compressor 10. Directly supplied from the condenser 20, and when the refrigerant is higher than a predetermined value compared to the temperature of the cooling water is to pass through the radiator 100.

이때, 상기 세방향 밸브(11)는 전자제어유니트(40)의 제어를 받아 동작하게 되는데, 상기 전자제어유니트(40)는 초기 시동시 냉매온도가 냉각수온도에 비해 15° 이상인 경우 냉매가 중공관(30)을 통과하면서 열교환을 하게 하는 것이 바람직하다.At this time, the three-way valve 11 is operated under the control of the electronic control unit 40, the electronic control unit 40 is a hollow tube when the refrigerant temperature is 15 ° or more than the coolant temperature at the initial start-up It is preferable to allow heat exchange while passing through (30).

또한, 냉매가 유동하게 되는 바깥쪽 중공관(30a)은 다시 냉매를 콘덴서(20)에 제공할 수 있도록 연결관(12)에 연관되어 있으며, 이렇게 냉각된 냉매가 냉동사이클계를 순환하면서 냉각 효율을 높여주게 되는 것이다.In addition, the outer hollow tube 30a through which the coolant flows is connected to the connecting pipe 12 so that the coolant can be supplied to the condenser 20 again. Will be raised.

이상에서 본 바와 같이 본 발명은 컴프레셔로부터 유출되는 냉매가 냉각수의 온도보다 높은 경우 라디에이터의 상부 탱크를 순환하면서 냉각수와 열교환을 할 수 있게 함으로써, 초기 시동시 냉각효율을 높일 수 있는 효과가 있다.As described above, the present invention allows the heat exchange with the coolant while circulating the upper tank of the radiator when the refrigerant flowing out of the compressor is higher than the temperature of the coolant, thereby increasing the cooling efficiency at the initial startup.
