Description

열교환기의 제조방법{Manufacturing method of heat exchanger}[0001] Manufacturing method of heat exchanger [0002]

본 발명은 열교환기의 제조방법에 관한 것으로, 더 상세하게는 하나의 열교환기 조립체를 절단하여 복수개의 열교환기를 제조할 수 있는 열교환기의 제조방법에 관한 것이다. The present invention relates to a method of manufacturing a heat exchanger, and more particularly, to a method of manufacturing a heat exchanger capable of manufacturing a plurality of heat exchangers by cutting one heat exchanger assembly.

일반적으로 냉장고 또는 자동차 등에 열교환기는, 열교환 매체의 특성 및 사용 압력에 따라 휜 튜브 타입, 서펜틴타입(serpentine type), 드론 컵 타입(drawn cup type), 패러렐 플로우 타입(parallel flow type)등 여러 종류의 것이 있다. Generally, a heat exchanger such as a refrigerator or an automobile has various types such as a fin tube type, a serpentine type, a drawn cup type, and a parallel flow type depending on the characteristics of a heat exchange medium and the working pressure. .

이러한 대부분의 열교환기는 열교환 매체를 방열 휜과 접촉된 튜브의 내부로 통과시켜 튜브 및 방열휜의 표면과 접촉되는 유동공기와 열교환이 이루어지도록 되어 있다.Most of the heat exchangers pass the heat exchange medium to the inside of the tube which is in contact with the heat dissipating fin, and heat exchange is performed with the flowing air contacting the surface of the heat dissipating fin.

상기 열교환기중 패러렐 프롤우 타입 열교환기는 나란히 배치된 한 쌍의 헤더 탱크와, 이 헤더 탱크들 사이에 나란히 배치되며 그 양단 부가 각각 상기 헤더 탱크에 형성된 튜브삽입공에 삽입되어 고정되는 다수의 튜브들과, 상기 튜브들 내에서 유동되는 열교환매체가 외부와 효과적으로 열교환 할 수 있도록 넓은 전열면적을 가지며 상기 튜브들 사이에 설치된 방열휜(fin)을 구비한다. Wherein the parallel flow type heat exchanger in the heat exchanger includes a pair of header tanks disposed side by side and a plurality of tubes arranged side by side between the header tanks and inserted and fixed to the tube insertion holes formed at both ends of the header tanks, And a heat dissipating fin having a large heat transfer area and disposed between the tubes so that the heat exchange medium flowing in the tubes can effectively exchange heat with the outside.

이와 같이 구성된 종래의 열교환기는 상호 평행하게 설치되는 헤더탱크의 튜브삽입공에 튜브들의 양단부가 삽입되고, 튜브들의 사이에 방열휜이 설치된 상태로 지그에 의해 지지되어 브레이징로에 투입된다. 이와 같이 지그에 지지되어 브레이징로에 유입된 열교환기는 헤더 탱크에 입혀진 클래드재가 녹아서, 상기 튜브와 헤더탱크가 접합되고, 상기 튜브들의 사이에 방열휜의 표면에 설치되는 클래드재가 녹아서 튜브들의 사이에 방열휜이 접합된다. In the conventional heat exchanger thus configured, both ends of the tubes are inserted into the tube insertion holes of the header tank installed parallel to each other, and the heat transfer fins are inserted between the tubes, and are supported by the jig and inserted into the brazing furnace. In the heat exchanger supported by the jig and thus introduced into the brazing furnace, the clad material clad on the header tank is melted, the tube and the header tank are joined, and the clad material installed on the surface of the heat dissipating fin is melted, The fins are joined.

상기와 같은 열교환기의 제조방법은 열교환기의 사이즈가 상대적으로 큰 경우 하나의 지그에 의해 조립이 이루어지는데, 상대적으로 지그를 이용한 조립에 따른 많은 작업공수가 소요되는 문제점이 있다. When the size of the heat exchanger is relatively large, the assembly of the heat exchanger is performed by a single jig. However, a relatively large number of operations are required for assembly using a jig.

이러한 점을 감안하여 일본 공개 특허 제 2008-116117호에는 상호 소정간격 이격되는 한 쌍의 헤더탱크부와, 상기 헤더 탱크부의 탱크길이 방향으로 복수 라인 적층되며 각각의 양단이 상기 헤더탱크부에 접속 되어 열교환 유체가 유통하는 열교환용의 튜브를 갖는 열교환기를 제조하기 위한 것으로, 상기 헤더탱크부의 사이에 튜브들을 배치하는 단계와, 상기 헤더탱크부 안의 공간을 상기 탱크의 길이 방향으로 차단하는 칸막이 부재들을 설치하는 단계와, 상기 복수의 칸막이 부재의 사이를 상기 튜브의 길이방향을 따라 절단함으로써 복수의 열교환기로 분리하는 단계를 포함한다. In view of this, Japanese Patent Application Laid-Open No. 2008-116117 discloses a fuel cell system comprising a pair of header tank portions spaced apart from each other by a predetermined distance, and a plurality of lines stacked in the tank longitudinal direction of the header tank portion, A method of manufacturing a heat exchanger having a tube for heat exchange through which a heat exchange fluid flows, comprising the steps of: arranging tubes between the header tank portions; installing partitioning members for blocking the space in the header tank portion in the longitudinal direction of the tank And dividing the plurality of partitioning members into a plurality of heat exchangers by cutting the space between the partitioning members along the longitudinal direction of the tube.

그러나 상술한 바와 같은 열교환기의 제조방법은 칸막이 부재들에 의해 구획된 헤더탱크 만을 길이 방향을 따라 절단하는 구조를 가지고 있으므로 튜브들의 사이에 위치되는 방열휜 또는 튜브를 절단하여야 하는 문제점이 있다.However, the method of manufacturing a heat exchanger as described above has a problem that only the header tank partitioned by the partitioning members is cut along the longitudinal direction, so that the heat dissipating fin or tube located between the tubes must be cut.

이러한 방열횐 또는 튜브의 절단은 많은 작업공수가 소요되는 문제점 이 있으며, 생산성의 향상을 도모하기 어렵다. 그리고 방열휜의 경우 절단면이 깨끗하게 절단되지 못함으로써 외관이 좋지 않은 문제점이 있다. Such heat dissipation or tube cutting requires a lot of work, and it is difficult to improve the productivity. In the case of the heat-dissipating fin, the cut surface is not cut cleanly, and thus the appearance is poor.
