라디에이터의 연결튜브 접합구조{Brazing structure of connecting tube in radiator}Brazing structure of connecting tube in radiator

본 고안은 라디에이터의 연결튜브 접합구조에 관한 것으로, 더욱 상세하게는 라디에이터의 냉매가 흐르는 튜브가 연통되게 하는 연결튜브를 결합하고 브레이징하여 견고하게 접합될 수 있는 라디에이터의 연결튜브 접합구조에 관한 것이다.The present invention relates to a connecting tube joining structure of the radiator, and more particularly to a connecting tube joining structure of the radiator that can be firmly joined by bonding and brazing the connecting tube through which the refrigerant flowing through the radiator.

라디에이터(radiator)는 냉각과 방열을 목적으로 한 매개체에서 다른 매개체로 열에너지를 전달하는데 쓰이는 열교환기이다. 그리고, 일반적인 라디에이터는 냉매가 흐르는 튜브와 상기 튜브의 외면에 방열핀 조립체와 결합되어 열 발산 되게 된다.Radiators are heat exchangers used to transfer thermal energy from one medium to another for the purpose of cooling and heat dissipation. In addition, the general radiator is coupled to the heat dissipation fin assembly on the tube and the outer surface of the tube through which the refrigerant flows to be dissipated heat.

여기서, 상기 튜브는 방열핀 조립체의 형성된 통공에 복수 개 결합되고, 상기 튜브가 연통되게 하기 위하여 연결튜브가 은납링으로 브레이징 접합되게 된다.Here, the plurality of tubes are coupled to the plurality of through-holes formed in the heat dissipation fin assembly, the connecting tube is brazed by a silver solder ring in order to communicate the tube.

도 1은 종래에 따른 라디에터의 연결튜브의 접합구조 단면도를 도시한 것이다.Figure 1 shows a cross-sectional view of the junction structure of the connection tube of the conventional radiator.

도 1을 참조하면, 은납링(20)이 튜브(10) 외주면에 삽입되고, 연결튜브(30)와 상기 튜브(10)와 끼워맞춤하며, 상기 은납링(20)이 연결튜브(30)의 결합 단부에 위치되고 가열되어 상기 튜브(10)와 연결튜브(30)가 접합되는 구조를 이루었다.Referring to FIG. 1, a silver solder ring 20 is inserted into an outer circumferential surface of the tube 10, fits with a connection tube 30 and the tube 10, and the silver solder ring 20 is connected to the connection tube 30. Located at the coupling end and heated to form a structure in which the tube 10 and the connecting tube 30 are bonded.

그러나, 상기와 같은 구조는 튜브와 결합된 연결튜브의 단부에 은납링이 압착되지 않아 튜브와 연결튜브를 접합하는데 어려움이 있어왔다.However, such a structure has been difficult to join the tube and the connection tube because the silver lead ring is not pressed to the end of the connection tube coupled to the tube.

그리고, 브레이징 작업이 진행되는 경우, 열에 의해 용융된 은납링이 연결튜브 내부로 침투되는 양이 적고, 튜브 외주면에 흐르는 양이 많아져 튜브와 연결튜브의 접합 강도가 약해지는 문제점이 있어왔다.In addition, when the brazing operation is performed, the amount of the silver solder ring melted by heat is less penetrated into the connecting tube, and the amount of flowing into the outer circumferential surface of the tube increases, thereby weakening the joint strength between the tube and the connecting tube.

본 고안은 상기와 같은 문제점을 해결하기 위하여 고안된 것으로, 은납링을 연결튜브의 단부에 압착되게 하고, 브레이징 작업에 의해 용융된 은납링이 상기 연결튜브 내부로 많은 양이 침투할 수 있도록 하는 라디에이터의 연결튜브 접합구조를 제공하고자 하는데 그 목적이 있다.The present invention has been devised to solve the above problems, the radiator of the radiator is to be pressed to the end of the connecting tube, the silver lead ring melted by the brazing operation to allow a large amount of penetration into the inside of the connecting tube. The purpose is to provide a connection tube joint structure.

상기와 같은 목적을 달성하기 위하여 본 고안은 복수 개의 통공이 형성된 방열핀 조립체에 튜브가 관통되고, 상기 복수 개의 튜브가 연통되도록 U자형 연결튜브의 양단과 튜브 단부가 결합되며, 결합된 튜브와 연결튜브의 외주면에 구비된 은납링이 브레이징되어 상기 튜브와 연결튜브가 접합되는 라디에이터의 연결튜브 접합구조에 있어서, 상기 튜브의 단부 외주면에 삽입되는 밴드링이 구비되어, 상기 밴드링과 연결튜브 사이에 구비된 은납링이 브레이징되어 상기 튜브와 연결튜브가 접합되되, 상기 밴드링은 단면 형상이 직사각형인 것을 특징으로 한다.In order to achieve the above object, the present invention provides a tube through a heat dissipation fin assembly in which a plurality of holes are formed, and both ends and tube ends of the U-shaped connecting tube are coupled so that the plurality of tubes communicate with each other. In the connection tube joining structure of the radiator is a silver lead ring provided on the outer circumferential surface of the radiator is joined to the tube and the connection tube, the band ring is inserted into the outer peripheral surface of the end of the tube, provided between the band ring and the connection tube The silver solder ring is brazed so that the tube and the connecting tube are joined, and the band ring has a rectangular cross-sectional shape.

여기서, 상기 튜브, 연결튜브 및 밴드링은, 재질이 구리인 것을 특징으로 한다.Here, the tube, the connecting tube and the band ring is characterized in that the material is copper.

그리고, 상기 밴드링은, 단면 형상이 직사각형인 것을 특징으로 한다.The band ring is characterized by having a rectangular cross-sectional shape.

상기와 같은 구성의 본 고안에 따르면, 다음과 같은 효과를 기대할 수 있을 것이다.According to the present invention of the configuration as described above, the following effects can be expected.

상기 튜브 외주면에 밴드링이 결합됨에 따라 은납링이 밴드링과 연결튜브 사이에 위치하게 되어 은납링의 위치가 고정될 수 있으며, 브레이징 작업으로 은납링이 용융되어 상기 튜브보다 돌출된 밴드링의 높이에 의해 튜브와 연결튜브의 결합 틈새 깊숙히 흘러들어가게 되므로 브레이징 작업이 간편하고 접합 품질이 높아지게 된다. As the band ring is coupled to the outer circumferential surface of the tube, the silver solder ring may be positioned between the band ring and the connection tube so that the position of the silver solder ring may be fixed, and the height of the band ring protruding from the tube may be due to melting of the silver solder ring by brazing operation. It flows deep into the coupling gap between the tube and the connecting tube, which makes brazing easier and improves the quality of the joint.
