브레이징 노를 이용한 콘덴서 헤더용 연결파이프 제조방법{Brazing low use condenser header for join-pipe of manufacture method}[0001] The present invention relates to a method of manufacturing a connection pipe for a condenser header using a brazing furnace,

본 발명은 브레이징 노를 이용한 콘덴서 헤더용 연결파이프 제조방법에 관한 것으로서, 더욱 상세하게는 동관으로 형성되어 헤더의 연결부재에 삽입되는 연결파이프의 외주연에 물과 동가루로 이루어진 페이스트 용접재를 디핑(dipping)한 뒤, 연결부재에 삽입하고, 브레이징 노에서 브레이징 용접함으로써, 전위부식 등이 발생되지 않고, 종래의 고가의 용접재를 사용하지 않아 제작비용이 절감되는 브레이징 노를 이용한 콘덴서 헤더용 연결파이프 제조방법에 관한 것이다.
The present invention relates to a method of manufacturing a connecting pipe for a condenser header using a brazing furnace, and more particularly, to a method of manufacturing a connecting pipe for a condenser header by dipping a paste- a connection for a condenser header using a brazing furnace which does not use conventional expensive welding materials and thus reduces manufacturing costs by dipping, then inserting it into a connecting member, brazing welding in a brazing furnace, To a pipe manufacturing method.

일반적으로, 응축기는 압축기로부터 유입된 고온·고압의 냉매가스를 냉각하여, 응축 액화시키기 위한 열교환기이다.Generally, a condenser is a heat exchanger for condensing and liquefying a high-temperature and high-pressure refrigerant gas introduced from a compressor.

이때에 응축기가 발열하는 열량은 증발기에서 흡수한 열량과 압축기에 의해 압축하는 데 소요된 압축 열량과의 합이다.At this time, the amount of heat generated by the condenser is the sum of the amount of heat absorbed by the evaporator and the amount of heat of compression required to be compressed by the compressor.

또한, 공조장치에 이용되는 응축기는 일반적으로 라디에이터의 전면에 탑재되어 외기로서 냉각되도록 주로 사용된다.In addition, a condenser used in an air conditioner is generally used so that it is mounted on the front surface of a radiator and cooled as the outside air.

종래의 응축기(condenser)는 압축기에서 유입된 고온,고압의 냉매를 일정한 냉매 유로를 형성하는 헤드 튜브와, 핀 튜브와, 리시브 헤드 튜브를 따라 지그재그로 흐르게 한 후, 그 외부에서 응축기용 송풍기를 가동시켜 외부공기와 열교환이 이루어지도록 구성되어 있다.Conventional condensers have a structure in which a high-temperature and high-pressure refrigerant introduced from a compressor flows in a staggered manner along a head tube, a fin tube, and a receiver head tube which form a constant refrigerant flow path, So that heat exchange with the outside air is performed.

즉, 응축기의 내부로 유입된 냉매는 정해진 유로를 통해 흐르는 동안 외부의 공기와 열교환 함으로써 냉각이 이루어져 엔탈피가 감소하며, 엔탈피가 감소하여 과냉각된 냉매는 응축기 연결 파이프를 통해 다음 공급처로 유입된다.That is, the refrigerant flowing into the inside of the condenser is cooled by heat exchange with the outside air while flowing through the predetermined flow path, the enthalpy decreases, and the enthalpy decreases, and the supercooled refrigerant flows into the next supply source through the condenser connecting pipe.

그런데, 상기 응축기는 알루미늄 재질로 형성되고, 상기 연결 파이프는 동관 재질로 형성되어 상호 연결시, 용접작업에 어려움이 있고, 어렵게 용접이 되어도 상호간에 재질이 달라 전위부식이 발생하는 문제점이 있다.However, the condenser is formed of an aluminum material, and the connecting pipe is formed of a copper pipe material, so that it is difficult to perform a welding operation when interconnected, and the material of the connecting pipe is different from each other even if it is difficult to weld.

이에, 상기 헤드 튜브와 연결 파이프 사이에 상호 연결하기 위한 연결부재가 더 형성되고, 상기 연결부재는 헤드 튜브와 연결 파이프에 각각 형성되며, 상기 연결부재가 상호 접촉되어 볼트 등의 연결수단에 의해 고정됨으로써, 헤드 튜브에 배출 파이프가 연결되는 것이다. 이때, 상기 연결부재는 스테인리스(SUS) 재질로 형성된다.The head tube and the connecting pipe are connected to each other by a connecting member. The connecting member is formed in the head tube and the connecting pipe. The connecting member is in contact with the head tube and the connecting pipe. Whereby the discharge pipe is connected to the head tube. At this time, the connecting member is made of stainless steel (SUS) material.

그런데, 상기 연결부재에 동관의 연결 파이프가 연결된 상태에서 용접이 이루어지는데, 종래에는 동관의 연결 파이프와 스테인리스 재질인 연결부재가 상호 용접하기 위해 은납을 이용하여 고주파 용접하였고, 은이 40%가량 함유되어 있기에 제조비용 등이 증가하는 문제점이 발생한다.
However, in the related art, welding is performed in a state where a connecting pipe of a copper pipe is connected to the connecting member. In the past, high frequency welding was performed using silver solder to weld the connecting pipe of the copper pipe and the connecting member made of stainless steel. There is a problem that the manufacturing cost increases.

도 1은 본 발명의 일실시예에 따른 연결파이프가 연결된 알루미늄 콘덴서를 나타낸 개략도이고, 도 2는 본 발명의 일실시예에 따른 연결부재와 연결파이프를 나타낸 단면도이다.FIG. 1 is a schematic view showing an aluminum condenser connected with a connecting pipe according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view illustrating a connecting member and a connecting pipe according to an embodiment of the present invention.

도 1 내지 도 2에 도시한 바와 같이, 본 발명의 브레이징 노를 이용한 콘덴서 헤더용 연결파이프 제조방법은 다양한 실시예에 따라 제조되는데, 본 발명의 기술에 앞서 우선, 상기 콘덴서(응축기,50)의 구조를 간단히 설명하면, 냉장고용 콘덴서(50)로써, 양측에 헤더(10)가 각각 형성되고, 상기 헤더(10)가 상호 대응되는 헤더(10)의 외주연에 다수개의 튜브(13)가 연결되도록 튜브 연결홀(미도시)이 길이방향으로 이격되어 다수개 형성되며, 상기 튜브 연결홀에 결합된 튜브(13)와 튜브(13) 사이 사이에 지그재그 형태로 형성된 핀(14)이 삽입되어 최종적으로 브레이징 접합에 의해 고정된다. 이때, 상기 콘덴서(50)는 알루미늄 재질 또는 스테인리스 재질로 형성된다.1 and 2, a method of manufacturing a connecting pipe for a condenser header using a brazing furnace according to the present invention is manufactured according to various embodiments. Prior to the description of the present invention, A plurality of tubes 13 are connected to the outer periphery of the header 10 in which the headers 10 correspond to each other, (Not shown) are spaced apart in the longitudinal direction, and a pin 14 formed in a zigzag shape is inserted between the tube 13 coupled to the tube connection hole and the tube 13, By brazing joints. At this time, the capacitor 50 is made of aluminum material or stainless material.

그리고, 상기 하나의 헤더(10) 외주연에는 연결파이프(20)와 연결되어 상기 연결파이프(20)를 통해 이송된 냉매가 헤더(10)의 내부에 유입되고, 상기 냉매는 헤더(10) 내를 이송하면서 상호 연통된 다수개의 튜브(13)를 통해 반대측 헤더(10)에 이송되면서 외부의 공기가 튜브(13)와 핀(14)의 외부를 지나가면서 열교환되어 내부에 이송되는 냉매는 응축되며, 상기 응축수는 다시 헤더(10)로 이송되어 다른 연결파이프(20)를 통해 외부로 배출되는 것이다.A refrigerant that is connected to the connection pipe 20 and transferred through the connection pipe 20 flows into the header 10 at the outer periphery of the header 10, The outside air is passed through the tube 13 and the outside of the fin 14 to be heat-exchanged, and the refrigerant transferred to the inside is condensed The condensed water is transferred to the header 10 and discharged to the outside through the other connecting pipe 20.

여기서, 상기 헤더(10)는 연결파이프(20)를 통해 냉매가 내부에 유입되도록 외주연 일단부(튜브(13)가 설치된 외주연의 반대측)에 유입구(11)가 형성되고, 상기 유입구(11)를 통해 유입된 냉매가 내부를 따라 이송되어 열교환 후, 외부로 배출되도록 외주연 타단부(튜브(13)가 설치된 외주연의 반대측)에 배출구(12)가 형성된다.The header 10 has an inlet 11 formed at one end of the outer periphery of the header 10 on the opposite side of the outer circumference where the tube 13 is installed to allow the refrigerant to flow in through the connecting pipe 20, (The opposite side of the outer periphery on which the tube 13 is provided) so as to be discharged to the outside after the heat exchange is carried out.

또한, 상기 연결파이프(20)는 헤더(10)의 유입구(11)와 배출구(12)에 각각 연결되어 외부에서 주입된 냉매를 이송시켜 헤더(10)에 유입 또는 상기 헤더(10)에서 배출된 응축된 냉매를 외부로 이송시키는 관으로써, 다양한 재질의 관을 사용하지만 본 발명에서는 냉매 이송에 탁월한 동관을 사용한다.The connection pipe 20 is connected to the inlet 11 and the outlet 12 of the header 10 to transfer the refrigerant injected from the outside to the header 10 or the header 10, As pipes for conveying the condensed refrigerant to the outside, pipes of various materials are used, but in the present invention, copper pipes excellent in refrigerant transfer are used.

그리고, 상기 연결파이프(20)는 도 2에 도시한 바와 같이, 연결부재(30)에 삽입되어 결합됨으로써 연결파이프(20)가 헤더(10)에 고정된다.2, the connection pipe 20 is inserted into and coupled to the connection member 30 so that the connection pipe 20 is fixed to the header 10. As shown in FIG.

여기서, 상기 연결부재(30)는 도 2에서처럼, 헤더(10)의 유입구(11)와 배출구(12)에 각각 설치되어 브레이징 접합에 의해 일체형으로 고정되고, 내부가 홀로 형성되어 유입구(11) 및 배출구(12)와 연통되며, 상기 연결파이프(20)가 연결부재(30)에 삽입되어 외부로 이탈되지 않도록 연결파이프(20)가 삽입된 연결부재(30)의 외주연이 연결파이프(20)의 관 둘레보다 크게 확관(擴管)된다.2, the connecting member 30 is installed in the inlet 11 and the outlet 12 of the header 10, and is integrally fixed by brazing. The connecting member 30 is formed integrally with the inlet 11 and the outlet 12, The outer circumference of the connecting member 30 into which the connecting pipe 20 is inserted is connected to the connecting pipe 20 so that the connecting pipe 20 is inserted into the connecting member 30 and is not released to the outside, Of the tube.

또한, 상기 연결부재(30)는 일측으로 통해 내부로 연결파이프(20)가 연결되는데, 상기 연결파이프(20)가 연결부재(30)의 내부에 지지되도록 내주연에 다단으로 형성된 단턱(미도시)이 형성되고, 상기 단턱에 연결파이프(20)의 일단부가 지지되어 더 이상 연결부재(30)의 내부로 삽입되는 것을 방지한다.
The connecting pipe 30 is connected to the connecting pipe 20 through one side of the connecting member 30 so that the connecting pipe 30 is supported inside the connecting member 30 by a multi- And the one end of the connecting pipe 20 is supported at the stepped portion to prevent the inserted pipe 20 from being inserted into the connecting member 30 any longer.

이렇듯, 상기 연결부재(30)의 확관된 부위에 연결파이프(20)가 삽입된 뒤, 브레이징 노에서 브레이징 접합되는데, 이때, 상기 연결파이프(20)가 동 재질이고, 연결부재(30)는 알루미늄 재질 또는 스테인리스 재질이기에 상호 용접시, 상호 간 접촉 부위에서 전위부식이 발생한다. The connection pipe 20 is inserted into the expanded portion of the connection member 30 and then brazed to the brazing furnace. At this time, the connection pipe 20 is made of copper, Because they are made of material or stainless steel, potential corrosion occurs at mutual contact points when welding.

여기서, 전위부식이란, 부식전위[corrosion potential]라고도 하는데, 부식이 진행 중인 금속의 조합전극(포화 감홍(甘汞) 전극, 염화은 전극 등)에 대한 전위를 말한다.Here, the potential erosion refers to a potential against a combination electrode (a saturated gamma electrode, a silver chloride electrode, etc.) of a metal undergoing corrosion, which is also referred to as a corrosion potential.

그렇기에 상기 헤더(10)의 연결부재에 삽입되는 부위에 페이스트 용접재를 디핑(dipping)한 뒤, 연결부재(30)에 삽입하고, 브레이징 노에서 브레이징 용접하여 연결하는 것이다.Therefore, the paste welding material is dipped into the connecting member of the header 10, inserted into the connecting member 30, brazed in the brazing furnace, and connected.

그리고, 상기 페이스트 용접재는 물과 동가루를 1 : 1 비율로 혼합하여 제조하는데, 조건에 따라 비율을 달라질 수 있다.The paste welding material is produced by mixing water and copper powder at a ratio of 1: 1. The ratio may vary depending on conditions.
