기밀부재를 이용한 보일러용 열교환기의 튜브 결합구조{Tube joint structure of heat exchanger of boiler using for sealing material}Tube joint structure of heat exchanger of boiler using for sealing material}

본 발명은 보일러용 열교환기에 관한 것으로, 더욱 상세하게는 열교환기에 설치되는 사이드플레이트에 기밀부재를 삽입하고 브레이징에 의해 튜브를 결합함으로써 튜브홀의 내·외측에서 동시에 밀봉 결합되어 확실한 기밀성을 확보할 수 있는 열교환기의 튜브 결합구조에 관한 것이다. The present invention relates to a heat exchanger for a boiler, and more particularly, by inserting an airtight member into a side plate installed in the heat exchanger and joining a tube by brazing, the airtight member is sealed at the same time inside and outside of the tube hole to ensure reliable airtightness. It relates to a tube coupling structure of the heat exchanger.

일반적으로 가스보일러는 버너에서 생성된 고온의 열을 이용하여 실내 난방 및 온수 사용을 위한 것으로, 열 교환기는 버너 위에 배치되어 버너 연소 시 발생하는 연소열을 흡수하여 튜브 내부에 흐르는 유체에 전달하여 유체를 승온시 킨다.In general, the gas boiler is for indoor heating and hot water using high temperature heat generated by the burner, and the heat exchanger is disposed on the burner to absorb the combustion heat generated when the burner is burned and transfer the fluid to the fluid flowing inside the tube to transfer the fluid. Increase the temperature.

도면 도 1를 참고하면, 열 교환기(8)는 기설정된 길이를 가지며 일 방향으로 배열되어 있고 유체가 유동할 수 있는 복수의 튜브(8a, 8b), 튜브(8a, 8b) 양측에 각각 배치되어 있고 이웃한 튜브(8a, 8b)의 간격을 유지하는 사이드플레이트(81a, 81b) 및 사이드플레이트(81a, 81b)에 각각 결합되어 있고 이웃한 튜브(1a, 1b) 내부를 연결하는 유로홈(821)이 복수 형성된 워터커넥터(82a, 82b)를 포함한다.Referring to FIG. 1, the heat exchanger 8 has a predetermined length, is arranged in one direction, and disposed on both sides of the plurality of tubes 8a and 8b and the tubes 8a and 8b through which fluid can flow. And a flow path groove 821 coupled to the side plates 81a and 81b and the side plates 81a and 81b, which maintain the spacing between the adjacent tubes 8a and 8b, respectively, and connecting the insides of the adjacent tubes 1a and 1b. Includes a plurality of water connectors 82a and 82b.

일측 워터커넥터(82a)에는 튜브(8a, 8b) 내부로 유체를 유입시키는 유입구(83)와 튜브(8a, 8b)를 통과한 유체가 배출되는 배출구(84)가 형성되어 있다.One water connector 82a is formed with an inlet port 83 for introducing fluid into the tubes 8a and 8b and a discharge port 84 through which the fluid passing through the tubes 8a and 8b is discharged.

사이드플레이트(81a, 81b)와 워터커넥터(82a, 82b)는 접합강도가 강하고 정교한 접합이 가능한 브레이징 공정에 의해 서로 접합된다. 브레이징 공정시, 사이드플레이트(81a, 81b)와 워터커넥터(82a, 82b)가 충분히 밀착되지 않으면 사이드플레이트(81a, 81b)와 워터커넥터(82a, 82b)가 접합되지 않는다 혹 접합된다 하더라도 불완전한 접합이 이루어지게 된다.The side plates 81a and 81b and the water connectors 82a and 82b are joined to each other by a brazing process in which bonding strength is strong and precise bonding is possible. In the brazing process, if the side plates 81a and 81b and the water connectors 82a and 82b are not sufficiently in contact with each other, the side plates 81a and 81b and the water connectors 82a and 82b will not be joined. Will be done.

이에 사이드플레이트(81a, 81b)와 워터커넥터(82a, 82b)를 밀착시킨 상태에서 특정 개소에 미리 스폿 용접을 하여 사이드플레이트(81a, 81b)와 워터커넥터(82a, 82b)를 충분히 밀착시켜 놓은 상태에서 일측 방향에서 주사기에 액상의 동성분문질을 경계부위에 도포하고, 브레이징 공정을 수행하게 된다.In the state where the side plates 81a and 81b and the water connectors 82a and 82b are in close contact with each other, spot welding is carried out at a specific point in advance so that the side plates 81a and 81b and the water connectors 82a and 82b are sufficiently in close contact with each other. At one side in the syringe is applied to the liquid isomeric fingerprints on the boundary area, and the brazing process is performed.

그러나 이러한 종래의 열교환기는 사이드플레이트에 복수의 튜브를 결합할 때 일측 방향에서 수작업에 의해 주사기로 도포작업후 브레이징 공정을 하기 때문에 시간 및 비용이 많이 소요될 뿐만 아니라, 기밀성이 떨어지는 문제점이 있었다.
