여기서, 상기 냉매관(10)은 알루미늄 합금 등의 열전도성이 높은 금속재로 이루어져 내부에는 냉매가 순환되고, 외벽에는 송풍장치 또는 자연 대류에 의해 공급되는 공기가 접촉되면서 열 교환이 이루어지도록 한다.Here, the refrigerant pipe 10 is made of a high thermal conductivity metal material, such as aluminum alloy, the refrigerant is circulated inside, the outer wall is in contact with the air supplied by the blower or natural convection so that the heat exchange is made.
그리고, 상기 핀(20)은 패널 모양으로 형성되어 상기 냉매관(10)에 직교되도록 다수개가 설치되어 냉매관(10)과 외부 공기와의 접촉 면적을 넓혀 열 교환 효율을 향상시킨다.In addition, the fins 20 are formed in a panel shape, and a plurality of fins 20 are installed to be orthogonal to the refrigerant pipe 10 to increase the contact area between the refrigerant pipe 10 and the outside air to improve heat exchange efficiency.
여기서, 상기 핀(20)과 상기 냉매관(10)은 일반적으로 알루미늄 합금 등의 열 전도성이 놓은 금속 재질로 이루어진다.Here, the fin 20 and the coolant pipe 10 are generally made of a metal material having thermal conductivity such as aluminum alloy.
그러나, 종래 기술에 따른 열교환기는 알루미늄 합금 등의 고가의 금속재로 제조되기 때문에 재료비의 소요가 많고, 열교환기 제작에 필요한 공정이 많아 생산 작업에 소요되는 비용 및 시간을 절감할 수 없는 어려움이 있다.However, since the heat exchanger according to the prior art is made of expensive metal materials such as aluminum alloy, it takes a lot of material cost, and there is a difficulty in reducing the cost and time required for the production work due to the large number of processes required for manufacturing the heat exchanger.

이하, 본 발명의 실시 예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명에 따른 열교환기가 도시된 사시도이다.2 is a perspective view showing a heat exchanger according to the present invention.
상기 본 발명에 따른 열교환기는 도 2에 도시된 바와 같이 냉매가 유출입되는 냉매유입구(52)가 일측에 형성된 냉매유입헤더(54)가 설치되고, 냉매가 유출되는 냉매유출구(60)가 일측에 형성된 냉매유출헤더(58)가 상기 냉매유입헤더(54)와 떨어져 대향되게 설치되며, 상기 냉매유입헤더(54)와 냉매유출헤더(58) 사이에는 다수의 행과 다수의 열방향으로 냉매관(56)이 설치되어 그 내부로 냉매가 통과되면서 외부의 공기와 열교환되는 유로를 형성한다.As shown in FIG. 2, the heat exchanger according to the present invention has a coolant inlet header 54 having a coolant inlet port 52 through which coolant flows in and out, and a coolant outlet 60 through which coolant flows out. A coolant outlet header 58 is disposed to face away from the coolant inlet header 54, and the coolant pipe 56 is disposed between the coolant inlet header 54 and the coolant outlet header 58 in a plurality of rows and a plurality of column directions. ) Is installed to form a flow path for heat exchange with the outside air as the refrigerant passes therein.
여기서, 상기 냉매관(56)은 열교환 면적을 넓히기 위하여 나선형으로 형성되는 것으로 성형성이 좋은 연질의 플라스틱으로 제조된다.Here, the coolant pipe 56 is formed in a spiral shape to increase the heat exchange area and is made of soft plastic having good moldability.
또는, 상기 냉매관(56)은 열교환 면적을 넓히기 위하여 다양한 형상으로 굴곡되게 제조될 수 있다.Alternatively, the coolant pipe 56 may be manufactured to be bent in various shapes to increase the heat exchange area.
상기한 바와 같이 상기 냉매관(56)은 압출에 의해 플라스틱으로 제조되는데 있어서, 플라스틱 수지가 고온의 성형부를 통과하면서 냉매관(56)이 나선형으로 성형되고, 상기 성형부를 통과한 냉매관(56)은 이와 연결된 저온의 형상고정부를 지나면서 냉매관(56)이 나선형상으로 고정됨으로 제조된다.As described above, the coolant pipe 56 is made of plastic by extrusion, and the coolant pipe 56 is spirally molded while the plastic resin passes through the hot molding part, and the coolant pipe 56 has passed through the molding part. The coolant tube 56 is manufactured by being fixed in a spiral shape while passing through a low temperature shape fixing part connected thereto.
상기와 같이 구성된 본 발명의 동작을 살펴보면 다음과 같다.Looking at the operation of the present invention configured as described above are as follows.
냉매유입구(52)를 지나 냉매유입헤더(54)를 통해 유입된 냉매는 나선형의 냉매관(56)을 지나면서 주위 공기와 열교환되고 냉매유출헤더(58)를 지나 냉매유출구(60)를 통해 빠져나간다.The refrigerant flowing through the refrigerant inlet 52 and passing through the refrigerant inlet header 54 passes through the spiral refrigerant pipe 56 and exchanges heat with ambient air, and passes through the refrigerant outlet header 58 and exits through the refrigerant outlet 60. I'm going.
이때, 상기 냉매관(56)은 금속제에 비해 열교환 효율이 떨어지는 플라스틱으로 제조되지만 나선형상으로 성형되기 때문에 직선으로 성형된 경우보다 열교환 면적을 넓혀주어 열교환 효율을 향상시킬 수 있다.At this time, the refrigerant pipe 56 is made of a plastic having a lower heat exchange efficiency than metal, but since it is molded in a spiral shape, it is possible to improve the heat exchange efficiency by widening the heat exchange area than when molded in a straight line.
상기와 같이 구성되는 본 발명에 따른 열교환기의 냉매관은 나선형으로 형성되기 때문에 핀이 생략되더라도 전열면적을 넓혀주어 열교환 효율을 향상시킬 수 있을 뿐 아니라 냉매관이 플라스틱으로 제조되기 때문에 나선형으로 제조하기 용이한 이점이 있다.Since the refrigerant pipe of the heat exchanger according to the present invention configured as described above is formed in a spiral shape, the heat transfer efficiency can be improved by widening the heat transfer area even if the fin is omitted, as well as manufacturing the spiral shape because the refrigerant pipe is made of plastic. There is an easy advantage.
