Description
본 고안은 자동차용 열교환기의 구조에 대한 것으로서, 더 상세하게는 탱크부의 강도를 향상시키고, 기밀성을 높이기 위해 탱크의 구조를 개량한데 특징이 있는 것이다.The present invention is directed to a structure of a heat exchanger for an automobile, and more particularly, to improve the strength of the tank portion and to improve the airtightness, which is characterized by improving the structure of the tank.
일반적으로 자동차의 인터쿨러나 오일쿨러에 사용하는 압출탱크 타입의 열교환기는 도 1에서 보는 바와 같이 구성되어 있다.In general, an extruded tank type heat exchanger used for an automobile intercooler or oil cooler is configured as shown in FIG. 1.
나란히 배열된 다수의 튜브(1)들과, 이들 튜브(1)의 끝단이 끼워진 헤더(2)와, 상기 헤더(2)의 양측 끝단 테두리(21) 안쪽으로 끼워진 탱크(3), 상기 탱크의 상측에 연결한 입/출 파이프(4)로 이루어져 있으며, 이들을 조립하고자 할 때는 튜브(1)들을 헤더(2)에 끼운 후, 헤더(2)에 탱크(3)를 조립한 상태에서 각각의 연결부위를 브레이징 가공하여 완성한다.A plurality of tubes 1 arranged side by side, a header 2 fitted with the ends of these tubes 1, a tank 3 fitted inside both end edges 21 of the header 2, and a It consists of inlet / outlet pipes (4) connected to the upper side. To assemble them, insert the tubes (1) into the header (2), and then connect each of them in the state of assembling the tank (3) to the header (2). Finish by brazing the site.
그러나 상기와 같은 종래의 열교환기는 탱크 내부에 고압이 채워질 경우 변형 및 크랙의 위험성이 많고, 탱크를 제조하기 위한 공법이 프레스 다공정에 의한 것이므로 금형의 개발이 어렵고 제조 비용이 높아지는 단점이 있다.However, the conventional heat exchanger as described above has a high risk of deformation and cracking when the tank is filled with high pressure, and the method for manufacturing the tank is due to a multi-press process, so that development of a mold is difficult and manufacturing costs are high.
따라서 본 고안은 상기와 같은 종래의 문제점을 감안하여 이를 해결 보완하고자 안출한 것으로서, 고안의 주된 목적은 헤더와 탱크를 브레이징 가공하되, 접촉면적을 넓게하고, 탱크의 구조를 개선하여 내부 압력이 높아지는데 대해 강도가 같이 높아질 수 있도록 하며, 제작비용이 저렴해 질 수 있도록 하는데 있다.Therefore, the present invention has been devised to solve the problem in view of the conventional problems as described above, the main purpose of the invention is to process the brazing header and tank, widen the contact area, improve the structure of the tank to increase the internal pressure It is to ensure that the strength can be increased together, and the manufacturing cost can be reduced.
이를 위한 특징적인 수단은 나란히 배열된 다수의 튜브들과, 이들 튜브의 끝단이 끼워지는 헤더와, 상기 헤더에 입출 파이프를 가진 탱크를 조립하여 이루어지는 자동차용 열교환기에 있어서, 상기한 탱크는 그 모서리부의 두께를 평면부의 두께 보다 더 두껍게 하고, 양측 끝단을 헤더의 저면까지 연장하여 헤더의 외측면 및 저면을 모두 감싸도록 하여 브레이징 가공하며, 양측 끝단을 마감부재로 밀폐하여 구성하는데 있는 것이다.A characteristic means for this is in an automotive heat exchanger comprising a plurality of tubes arranged side by side, a header into which the ends of these tubes are fitted, and a tank having inlet and outlet pipes in the header, wherein the tank has a corner portion thereof. The thickness is made thicker than the thickness of the flat portion, and both ends are extended to the bottom of the header to cover both the outer surface and the bottom of the header to be brazed, and both ends are sealed by a finishing member.

이하 본 고안의 실시예에 따른 구성 및 작용을 첨부 도면에 따라 보다 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도 3은 본 고안에 따른 열교환기의 정면도이고, 도 4는 본 고안 열교환기의 요부 구성도이다.3 is a front view of a heat exchanger according to the present invention, and FIG. 4 is a main configuration diagram of the heat exchanger of the present invention.
상기 도면에서 보듯이 나란히 배열된 다수의 튜브(1)들과, 이들 튜브(1)의 끝단이 끼워지는 헤더(2)와, 상기 헤더(2)에 입출 파이프(4)를 가진 탱크(3)를 조립하여 자동차용 열교환기를 완성하되, 본 고안에서는 상기한 탱크(3)를 압출 성형 방법으로 제작하여 모서리부(31) 두께(T1)를 평면부(32)의 두께(T2) 보다 더 두껍게 하고, 양측 하단(33)을 헤더(2)의 저면까지 연장하여 헤더(2)의 외측면 및 저면을 모두 감싸도록 한 상태로 브레이징 가공하며, 이후, 탱크(3)의 양측 끝단을 마감부재(34)로 밀폐하여 구성한다.As shown in the figure, a tank 3 having a plurality of tubes 1 arranged side by side, a header 2 into which the ends of these tubes 1 are fitted, and an entry and exit pipe 4 in the header 2. To complete the heat exchanger for the automobile, but in the present invention, the tank 3 is manufactured by an extrusion method to make the edge portion 31 thickness T1 thicker than the thickness portion T2 of the flat portion 32. Brazing is performed in such a state that both lower ends 33 extend to the bottom of the header 2 so as to cover both the outer and bottom surfaces of the header 2, and then ends of both ends of the tank 3 are closed. It is sealed by).
이상과 같이 구성된 본 고안의 조립 공정을 보면, 1차적으로 튜브(1)들을 헤더(2)에 수직으로 끼운 상태로 하고, 2차적으로 탱크(3)의 상단에 입/출 파이프(4)를 끼운 상태로 한 후, 이들 헤더(2) 및 탱크(3)를 조립한다.In the assembly process of the present invention configured as described above, the tube 1 is first inserted perpendicularly to the header 2, and the inlet / outlet pipe 4 is secondarily attached to the upper end of the tank 3. After the insertion, these headers 2 and the tank 3 are assembled.
즉, 탱크(3)의 양측 하단(33)이 상기한 헤더(2)의 저면에 맞닿도록 한 상태에서 길이 방향으로 끼워 넣어 조립하고, 이후 브레이징 가공한다.That is, the lower end 33 of both sides of the tank 3 is assembled in the longitudinal direction in the state which contacted the bottom face of the said header 2, and is brazed.
위에서 상세히 설명한 바와 같은 본 고안은 탱크(3)를 압출 성형방법으로 제작하여 양측 모서리부(31)의 두께(T1)를 평면부(32)의 두께(T2) 보다 두꺼웁게 형성하였기 때문에 강도가 보강되는 것이며, 탱크(3)의 양측 하단(33)을 헤더(2)의 측면은 물론 저면까지 닿도록 한 상태에서 브레이징 가공하고, 또, 그 양측 끝단을 별도의 마감부재(34)로써 차단하였기 때문에 기밀성이 크게 향상되는 것이다.The present invention, as described in detail above, the tank 3 is manufactured by an extrusion molding method, so that the thickness T1 of both edge portions 31 is formed to be thicker than the thickness T2 of the flat portion 32, so that the strength is reinforced. Since the lower end 33 of both sides of the tank 3 touches the side surface of the header 2 as well as the bottom surface, the brazing process is performed, and both ends thereof are blocked by a separate finishing member 34. Confidentiality is greatly improved.
