본 발명은 라디에이터의 연결튜브 접합방법 및 그에 따른 라디에이터의 연결튜브 접합구조에 관한 것으로, 더욱 상세하게는 라디에이터의 냉매가 흐르는 튜브를 연통되게 하는 연결튜브를 브레이징으로 견고하게 접합할 수 있는 라디에이터의 연결튜브 접합방법 및 그에 따른 라디에이터의 연결튜브 접합구조에 관한 것이다.The present invention relates to a connection method of the connection tube of the radiator and the connection structure of the connection tube of the radiator, and more particularly, to the connection of the radiator that can be firmly bonded to the connection tube for communicating the tube flowing through the refrigerant of the radiator It relates to a tube joining method and a connection tube joining structure of the radiator accordingly.

라디에이터(radiator)는 냉각과 방열을 목적으로 한 매개체에서 다른 매개체로 열에너지를 전달하는데 쓰이는 열교환기이다. 그리고, 일반적인 라디에이터는 냉매가 흐르는 냉각튜브와 상기 냉각튜브의 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 cooling tube and the outer surface of the cooling tube flowing refrigerant is to be heat dissipation.

여기서, 상기 냉각튜브는 직선방향으로 배열된 다수 개의 튜브와 상기 튜브를 연통되게 하는 연결튜브가 브레이징 접합되어 냉각 순환 구조를 이룰 수 있게 된다.Here, the cooling tube is a plurality of tubes arranged in a linear direction and the connecting tube for communicating the tube can be brazed to form a cooling circulation structure.

도 1은 종래에 따른 라디에이터의 연결튜브의 접합방법 예시도를 도시한 것이다.Figure 1 shows an example of the bonding method of the connection tube of the radiator according to the prior art.

도 1을 참조하면, 먼저, 삽입링(20)이 튜브(10) 외관에 삽입되고, 연결튜브(30)의 단부를 확관하여 상기 튜브(10)와 끼워맞춤하며, 상기 튜브(10)와 연결튜브(30)의 경계선에 위치한 삽입링(20)이 가열되어 튜브(10)와 연결튜브(30)를 접합하였다.Referring to Figure 1, first, the insertion ring 20 is inserted into the tube 10, the end of the connecting tube 30 is fitted with the tube 10, and is connected to the tube 10 Insertion ring 20 located at the boundary of the tube 30 was heated to bond the tube 10 and the connecting tube 30.

그러나, 상기와 같은 방법은 삽입링이 튜브와 연결튜브의 경계선에서 위치하여 외부로 노출되고, 삽입링이 직접 가열되어 브레이징되는 방법을 사용하여왔다. 이러한 방법은 삽입링이 튜브와 연결튜브의 외부 경계선에서 용융되어 연결튜브 내부로 흘러들어가야 하기 때문에 튜브가 항상 연결튜브 상부에 위치해야되는 제한적 조건이 있어 접합하는데 어려움이 있어왔다.However, the above method has used a method in which the insertion ring is positioned at the boundary between the tube and the connecting tube and exposed to the outside, and the insertion ring is directly heated and brazed. This method has been difficult to join because of the limited conditions that the insertion ring must melt at the outer boundary of the tube and the connecting tube and flow into the connecting tube.
