열교환기의 냉매파이프 고정용 브레이징링{Brazingring for Fixing Refrigerants Pipe of Heat Exchanger}Brazing Ring for Fixing Refrigerants Pipe of Heat Exchanger

본 발명은 열교환기의 냉매파이프를 브래킷에 접합시키는 브레이징링에 관한 것으로, 더 상세하게는 공극을 최소화하여 브레이징 불량률을 감소시키고, 냉매파이프를 기밀하고 견고하게 접합시킬 수 있도록 한 열교환기의 냉매파이프 고정용 브레이징링에 관한 것이다.The present invention relates to a brazing ring for joining a refrigerant pipe of a heat exchanger to a bracket, and more particularly, a refrigerant pipe of a heat exchanger capable of minimizing voids to reduce a brazing defect rate and sealing and reliably bonding a refrigerant pipe. It relates to a fixing brazing ring.

일반적으로 에어컨 등으로 이용되는 열교환기의 콘덴서는 도 1에 도시된 바와 같이, 헤더파이프(1)에 적정 간격을 두고 다수개의 튜브삽입홀(1a)을 형성하고, 상기 헤더파이프(1)의 튜브삽입홀(1a)에 냉매흐름용 튜브(2)를 결합시키며, 상기 튜브(2)들의 사이에는 방열을 위한 방열핀(3)을 설치한다.In general, a condenser of a heat exchanger used as an air conditioner, as shown in FIG. 1, forms a plurality of tube insertion holes 1a at appropriate intervals in the header pipe 1, and the tube of the header pipe 1. The refrigerant flow tube 2 is coupled to the insertion hole 1a, and the heat dissipation fins 3 for dissipation are installed between the tubes 2.

이러한 열교환기용 헤더파이프(1)는 두 개의 파이프를 다수의 튜브(2)와 연결하는 것으로서 오늘날 대표적인 공조 제품의 하나라고 할 수 있다. 이때, 상기 헤더파이프(1)는 알루미늄 또는 알루미늄 합금으로 제작되고, 헤더파이프(1)에는 알루미늄 또는 알루미늄 합금으로 제작된 냉매유입 및 냉매유출용 냉매파이프(4)가 브래킷(5)을 통해 연결된다.This heat exchanger header pipe (1) is to connect two pipes with a plurality of tubes (2) can be said to be one of the representative air conditioning products today. In this case, the header pipe 1 is made of aluminum or an aluminum alloy, and the refrigerant pipe 4 for refrigerant inlet and refrigerant outflow made of aluminum or aluminum alloy is connected to the header pipe 1 through the bracket 5. .

한편, 도 2와 도 3에서와 같이 냉매파이프(4)의 플랜지(4a)와 브래킷(5)의 안착홈(5a) 사이에는 브레이징 시 용가제 역할을 수행하는 브레이징링(6)이 장착된다.Meanwhile, as illustrated in FIGS. 2 and 3, a brazing ring 6 is installed between the flange 4a of the refrigerant pipe 4 and the seating groove 5a of the bracket 5 to serve as a solvent during brazing.

따라서 도 3에서와 같이 냉매파이프(4)를 브래킷(4a)에 조립한 상태에서 이를 고열의 브레이징 노를 통과시키면, 브레이징링(6)이 용융되면서 냉매파이프(4)의 플랜지(4a)부위와 브래킷(5)의 안착홈(5a)부위를 자연스럽게 융착하여 기밀하고 견고하게 접합시킨다.Therefore, as shown in FIG. 3, when the refrigerant pipe 4 is assembled to the bracket 4a and passed through a high-temperature brazing furnace, the brazing ring 6 is melted and the flange 4a of the refrigerant pipe 4 The seating groove 5a of the bracket 5 is naturally fused to be hermetically and firmly joined.

그러나 도 2,3과 도 4,5에서와 같이 종래의 브레이징링(6)은 그 단면이 단순히 원형으로 형성되었기 때문에, 냉매파이프(4)의 플랜지(4a)부위와 브래킷(5)의 안착홈(5a) 사이의 공극이 크게 발생하고 구조적으로 브레이징링(6)의 용접면적이 작아 브레이징 불량률이 상승하는 문제점이 있었으며, 또한 이로 인해 냉매파이프(4)를 브래킷(5)에 기밀하고 견고하게 접합시킬 수 없는 문제점이 있었다.However, as shown in FIGS. 2, 3 and 4 and 5, since the conventional brazing ring 6 is simply formed in a circular shape, the flange 4a portion of the refrigerant pipe 4 and the seating groove of the bracket 5 are shown. There was a problem that a large gap between the (5a) occurs and structurally the welding area of the brazing ring (6) is small, the brazing defect rate is increased, and because of this, the refrigerant pipe (4) is hermetically and firmly bonded to the bracket (5) There was a problem that can not be.

본 발명의 목적은 상기에서와 같은 종래의 결점을 해소하기 위해 발명한 것으로, 브레이징링의 구조를 개선하여 공극을 최소화함과 동시에 용접면적을 크게 확장시키고, 이를 통해 브레이징성을 향상시켜 불량률을 감소시킬 수 있도록 하며, 그리고 냉매파이프를 한층 더 기밀하고 견고하게 접합시킬 수 있도록 한 열교환기의 냉매파이프 고정용 브레이징링을 제공하는데 있다.An object of the present invention is to invent the conventional drawbacks as described above, to improve the structure of the brazing ring to minimize the voids and at the same time to greatly expand the welding area, thereby improving the brazing properties to reduce the defective rate It is possible to provide a brazing ring for fixing a refrigerant pipe of a heat exchanger, which can be used to make it possible to bond the refrigerant pipe more tightly and firmly.

상기 목적을 달성하기 위해 본 발명은 냉매유입 및 냉매유출용 냉매파이프의 플랜지와 브래킷의 안착홈 사이에 장착되어 브레이징 시 용가제 역할을 수행하는 브레이징링에 있어서, 상기 냉매파이프의 플랜지와 브래킷의 안착홈 사이 공극을 최소화하고 용접면적을 확장시킬 수 있도록 브레이징링의 단면을 종래와 달리 원형이 아닌 두께 대비 길이가 긴 다각형 또는 타원형으로 형성한 것이다.In order to achieve the above object, the present invention is mounted between a flange of a refrigerant pipe for refrigerant inlet and a refrigerant discharge and a seating groove of a bracket, and in brazing ring serving as a solvent during brazing, seating of the flange and bracket of the refrigerant pipe. In order to minimize the gap between the grooves and to expand the welding area, the cross section of the brazing ring is formed as a polygon or oval having a long length to the thickness rather than a circular shape.

본 발명에 따르면 브레이징 시 용가제 역할을 수행하는 브레이징링의 단면구조를 두께 대비 길이가 긴 다각형 또는 타원형으로 개선하여 공극을 최소화함과 동시에 용접면적을 크게 확장시킬 수 있기 때문에, 이를 통해 브레이징성이 향상되므로 브레이징 불량률을 크게 감소시킬 수 있으며, 그리고 냉매파이프를 브래킷에 한층 더 기밀하고 견고하게 접합시킬 수 있는 효과가 있다.According to the present invention, since the cross-sectional structure of the brazing ring, which serves as a solvent during brazing, can be improved to a polygon or oval having a long length to thickness, the welding area can be greatly expanded while minimizing voids, thereby providing brazing property. As a result, the brazing failure rate can be greatly reduced, and the refrigerant pipe can be more tightly and firmly bonded to the bracket.
