Description

라디에이터 및 이의 제조방법{Radiator and method for manufacturing the same}Radiator and method for manufacturing the same

본 발명은 라디에이터 및 이의 제조방법에 관한 것으로서, 보다 상세하게는 냉각수를 열교환시키는 라디에이터 및 이의 제조방법에 관한 것이다.The present invention relates to a radiator and a method for manufacturing the same, and more particularly, to a radiator for exchanging cooling water and a method for manufacturing the same.

일반적으로 차량의 엔진 룸 내에는 엔진 등과 같은 구동을 위한 부품뿐만 아니라, 엔진 등과 같은 차량 내 각 부품을 냉각하거나 또는 차량 실내의 공기 온도를 조절하기 위한 라디에이터, 인터쿨러, 증발기, 응축기 등과 같은 다양한 열교환기들이 구비된다. 이와 같은 열교환기들은 일반적으로 내부에 열교환매체가 유통하며, 열교환기 내부의 열교환매체와 열교환기 외부의 공기가 서로 열교환함으로써 냉각 또는 방열이 이루어지게 된다.In general, in the engine room of a vehicle, various heat exchangers such as radiators, intercoolers, evaporators, condensers, etc. for cooling each component in the vehicle, such as the engine, or adjusting the air temperature inside the vehicle, as well as parts for driving such as the engine, etc. are provided In such heat exchangers, a heat exchange medium generally circulates therein, and the heat exchange medium inside the heat exchanger and the air outside the heat exchanger exchange heat with each other, thereby cooling or dissipating heat.

그리고 상기 변화단계(C)는 상기 확관장치(130)를 상기 튜브(120) 측으로 가압하여, 상기 튜브(120)의 개구부를 변화시키는 단계이다.And the changing step (C) is a step of changing the opening of the tube 120 by pressing the tube expansion device 130 toward the tube (120).

상기 변화단계(C)에서는 상기 확관부(132)를 상기 튜브(120)의 중앙부(124)로 삽입하여 상기 튜브(120)의 중앙부(124)를 확관시키고, 상기 튜브(120)의 측면부(125)를 상기 압착홈(137)에 삽입하여 압착시킨다.In the changing step (C), the expansion tube 132 is inserted into the central portion 124 of the tube 120 to expand the central portion 124 of the tube 120, and the side portion 125 of the tube 120 ) is inserted into the compression groove 137 and compressed.

이로 인해, 상기 복수개의 제2튜브(123)의 냉각수가 적게 흐르게 하여 내구성이 향상되어 열적 팽창 및 수축에 유리한 형태를 갖게 된다.Due to this, the cooling water of the plurality of second tubes 123 flows less, so that durability is improved, so that it has an advantageous shape for thermal expansion and contraction.

또한, 상기 확관부(132)는 상기 튜브(120)에서 보았을 때의 좌우 측면으로 서로 이격되도록 배치되는 한 쌍의 확관부재(134)를 포함한다.In addition, the expansion tube 132 includes a pair of expansion members 134 arranged to be spaced apart from each other in the left and right side when viewed from the tube (120).

그리고, 상기 한 쌍의 확관부재(134)는 제1확관부재(135)가 인접하는 다른 제2확관부재(136) 측으로 향할수록, 상기 튜브(120)와 대향하는 측의 면이 상기 확관본체부(131) 측으로 기울어지도록 형성된다. 이로 인해 상기 튜브(120)와 상기 확관장치(130)의 간격이 밀착될 수 있게 함에 따라 상기 튜브(120)의 중앙부(124)에 쉽게 확관이 가능하다. In addition, as the pair of expansion members 134 is directed toward the other second expansion member 136 to which the first expansion member 135 is adjacent, the surface on the side opposite to the tube 120 is the expansion body part. (131) is formed to be inclined to the side. Due to this, as the distance between the tube 120 and the tube expansion device 130 can be closely contacted, the tube 120 can be easily expanded to the central portion 124 of the tube 120 .

종래의 라디에이터는 소재두께를 얇게 하도록 구성됨에 따라 내구성이 현저히 떨어지게 되어 엔진의 냉각수가 열교환기로 공급되면서 열적 팽창 및 수축이 반복될 경우 큰 온도차에 의하여 튜브에서 반복적으로 응력이 가해짐으로써 튜브가 손상이 되는 문제가 발생한다.As the conventional radiator is configured to have a thin material, the durability is significantly lowered, and when thermal expansion and contraction are repeated while the engine coolant is supplied to the heat exchanger, the tube is damaged by repeated stress by a large temperature difference problem arises.

또한, 내구성 강화를 위한 추가설비를 구축 하려는 경우 비용 증대와 함께 공정추가로 인한 생산성이 저하되는 문제점이 있었다.In addition, there was a problem in that the cost increased and productivity decreased due to the addition of the process in the case of constructing additional facilities to enhance durability.

여기서, 본 발명의 일 실시예에 따른 라디에이터(100)와 같이, 상단부와 하단부의 튜브(120)에 확관장치(130)를 배치시켜 튜브(120)의 중앙부(124)는 확관시키고 튜브(120)의 측면부(125)는 압착시킴으로써 냉각수를 적게 흐르게 하여 내구성이 향상된 라디에이터(100) 형성이 가능하다. Here, like the radiator 100 according to an embodiment of the present invention, the tube expansion device 130 is disposed on the tube 120 at the upper end and the lower end so that the central portion 124 of the tube 120 is expanded and the tube 120 is expanded. The side portion 125 of the side portion 125 is compressed by allowing less cooling water to flow, so that it is possible to form the radiator 100 with improved durability.

또한, 상기 라디에이터(100)의 내부 구조를 개선하여 내구성 강화를 위한 별도의 추가설비 구축이 필요 없게 되어 공정추가로 인한 불필요한 낭비를 줄일 수 있다. In addition, by improving the internal structure of the radiator 100, there is no need to construct a separate additional facility for enhancing durability, thereby reducing unnecessary waste due to the addition of a process.
