Description

열교환기용 원통형 분배관과 분기관의 결합 구조체{Distribute pipe and branch pipe coupling structure for heat exchanger}Distribute pipe and branch pipe coupling structure for heat exchanger

본 발명은 열교환기용 원통형 분배관과 분기관의 결합 구조체에 관한 것으로서, 보다 상세하게는 원통형 분배관의 표면에 폭방향 곡면과 길이방향 수평면을 가지는 결합공이 천공 형성되고 분기관의 단부에 상기 결합공에 대응되는 결합면과 비딩이 형성되어 상호간 대면부위가 용이하게 용접 결합되도록 할 수 있는 열교환기용 원통형 분배관과 분기관의 결합 구조체에 관한 것이다. The present invention relates to a coupling structure between a cylindrical distribution pipe and a branch pipe for a heat exchanger, and more particularly, a coupling hole having a curved surface in the width direction and a horizontal surface in the longitudinal direction is formed on the surface of the cylindrical distribution pipe, and the coupling hole is formed at the end of the branch pipe. It relates to a coupling structure of a cylindrical distribution pipe and a branch pipe for a heat exchanger capable of easily welding-coupled to each other by forming a coupling surface and a bead corresponding to each other.

일반적으로, 열교환기는 열매나 냉매의 이동 및 순환을 가능하게 하여 외기의 온도를 열교환시키는 장치로서, 열매나 냉매가 이동되는 분배관과 상기 분배관으로부터 복수개로 분기되는 분기관을 포함한다.In general, a heat exchanger is a device for exchanging temperature of outside air by allowing the movement and circulation of a medium or refrigerant, and includes a distribution pipe through which the medium or refrigerant is moved and a branch pipe branched from the distribution pipe in a plurality.

여기서, 종래의 열교환기는, 도 1에 도시된 바와 같이, 분배관(10)의 측면에 복수개의 결합공(11)이 천공된 후 그 결합공(11) 마다 분기관(20)의 단부가 용접되면서 연결되는 구성을 가지고, 분배관(10)에 분기관(20)의 용접 작업이 용이하도록 하기 위하여, 원통 형상으로 제조되는 분배관(10)의 측면에 결합공(11) 천공시 분배관(10)의 외부로부터 내부를 향하면서 결합공(11)을 천공하고 다시 내부로부터 외부로 향하면서 천공 부분이 소정의 높이로 돌출되는 플랜지(12)가 형성되도록 한 후, 원통 형상의 분기관(20) 단부가 플랜지(12)를 통해 결합공(11)에 삽입되도록 하고 있다. Here, in the conventional heat exchanger, as shown in FIG. 1, after a plurality of coupling holes 11 are drilled on the side of the distribution pipe 10, the end of the branch pipe 20 is welded for each coupling hole 11 In order to facilitate the welding work of the branch pipe 20 to the distribution pipe 10 while being connected, the coupling hole 11 on the side of the distribution pipe 10 manufactured in a cylindrical shape when drilling the distribution pipe ( 10) After drilling the coupling hole 11 from the outside to the inside, and again facing the outside from the inside to form a flange 12 in which the punched portion protrudes to a predetermined height, the cylindrical branch pipe 20 ) The end is inserted into the coupling hole 11 through the flange 12.

그러나 종래의 열교환기는, 분배관(10)의 결합공(11)에 분기관(20)의 단부를 삽입한 상태에서 분기관(20)의 외주면, 결합공(11) 및 플랜지(12)를 커버하면서 용접이 실시되기 위해서는, 분배관(10)의 결합공(11)에 삽입되는 분기관(20)의 길이를 작업자가 일일이 손으로 잡으면서 유지시켜야 하기 때문에, 분배관(10)에 결합공(11)과 플랜지(12)가 형성됨에도 용접 작업이 불편한 문제점이 있다.However, the conventional heat exchanger covers the outer circumferential surface of the branch pipe 20, the coupling hole 11 and the flange 12 with the end of the branch pipe 20 inserted into the coupling hole 11 of the distribution pipe 10. While welding is performed, the length of the branch pipe 20 inserted into the coupling hole 11 of the distribution pipe 10 must be maintained while the operator is holding it with his hand, so the coupling hole ( Even though 11) and the flange 12 are formed, there is a problem that the welding operation is inconvenient.

즉, 분배관(10)으로부터 분기관(20)으로 냉매나 열매가 효율적으로 분기되도록 하기 위해서는 분배관(10) 내부로 분기관(20) 단부가 최소한으로 삽입되어야 하는데, 이를 위해서는, 작업자가 분기관(20)의 단부가 결합공(11)으로부터 연장되는 플랜지(12)의 높이에 대응되는 위치를 가지도록 해야 하므로, 작업성이 크게 저하되는 문제점이 있다. That is, in order to efficiently branch the refrigerant or fruit from the distribution pipe 10 to the branch pipe 20, the end of the branch pipe 20 must be inserted to the inside of the distribution pipe 10 at a minimum. Since the end of the engine 20 must have a position corresponding to the height of the flange 12 extending from the coupling hole 11, there is a problem that workability is greatly reduced.

또한, 상기와 같은 이유로, 분배관(10)으로부터 분기관(20)이 수직하게 연결되지 못하고 복수개의 분기관(20)이 삐뚤빼뚤하게 결합되어 정렬이 제대로 되지 않아 미관상 좋지 못하고 제품의 완성도가 저하되는 문제점이 있다.In addition, for the same reason as above, the branch pipe 20 is not vertically connected from the distribution pipe 10, and the plurality of branch pipes 20 are crookedly coupled, so that the alignment is not good, resulting in poor aesthetics and lowering the completeness of the product. There is a problem.

도 2 내지 도 5에 도시된 바와 같이, 본 발명의 바람직한 실시예에 따른 열교환기용 원통형 분배관과 분기관의 결합 구조체는, 원통 형상을 가지는 분배관(10)의 측면에 폭방향으로 곡면(11a)을 가지고 길이방향으로 수평면(11b)을 가지면서 천공 형성되는 복수개의 결합공(11), 원통 형상을 가지는 분기관(20)의 단부에 결합공(11)에 대응되도록 전후 방향의 요부(21a)와 좌우 방향의 철부(21b)가 만곡 형성되는 결합면(21) 및 결합면(21)의 외주면에 단부로부터 소정간격 이격된 상태에서 결합면(21)의 요부(21a)와 철부(21b)의 만곡된 라인을 따라 소정의 두께로 형성되어 결합면(21)이 결합공(11)에 대면시 결합공(11)의 외주연에 안착되는 비딩(22)을 포함하고, 결합공(11), 결합면(21) 및 비딩(22)의 결합부위가 용접을 통해 접합된다.As shown in Figs. 2 to 5, the coupling structure of the cylindrical distribution pipe and the branch pipe for a heat exchanger according to a preferred embodiment of the present invention is curved in the width direction on the side surface of the distribution pipe 10 having a cylindrical shape (11a). ) And having a horizontal surface (11b) in the longitudinal direction and a plurality of coupling holes (11) that are perforated, and a recess (21a) in the front-rear direction to correspond to the coupling hole (11) at the end of the branch pipe (20) having a cylindrical shape ) And the convex portion (21b) in the left-right direction is curved, the concave portion (21a) and the convex portion (21b) of the coupling surface (21) in a state spaced apart from the end by a predetermined distance on the outer peripheral surface of the coupling surface (21) It is formed with a predetermined thickness along the curved line of, and includes a bead 22 that is seated on the outer periphery of the coupling hole 11 when the coupling surface 21 faces the coupling hole 11, and the coupling hole 11 , The bonding portion of the bonding surface 21 and the beading 22 are joined through welding.

분배관(10)은, 일단 또는 타단에 열교환을 위한 냉매나 열매 즉, 유체의 공급이나 회수가 가능하도록 하는 파이프부재로서, 원통 형상을 가지는 파이프부재가 소정의 길이로 절단된 후, 일단부가 스웨이징되어 중공이 폐쇄되고 타단부가 스웨이징되어 축관이 연장되며, 축관을 통해 유체가 충전된다. The distribution pipe 10 is a pipe member capable of supplying or recovering a refrigerant or heat medium, that is, a fluid for heat exchange at one end or the other end. After the pipe member having a cylindrical shape is cut to a predetermined length, one end thereof is The hollow is closed and the other end is swaged to extend the shaft pipe, and the fluid is filled through the shaft pipe.

분배관(10)은, 열전도율이 높은 금속, 보다 바람직하게는 동(銅) 재질을 가지는 것이 좋다.The distribution pipe 10 is preferably made of a metal having a high thermal conductivity, more preferably a copper material.

한편, 분배관(10)은, 복수개의 분기관(20) 결합을 위하여 측면에 복수개의 결합공(11)이 천공된다.On the other hand, the distribution pipe 10, a plurality of coupling holes 11 are perforated on the side for coupling a plurality of branch pipes 20.

여기서, 결합공(11)은, 분배관(10)이 원통 형상을 가짐에 따라 폭방향으로 곡면(11a)을 가지고 길이방향으로 수평면(11b)을 가지면서 원형으로 형성된다.Here, the coupling hole 11 is formed in a circular shape while having a curved surface 11a in the width direction and a horizontal surface 11b in the length direction as the distribution pipe 10 has a cylindrical shape.

따라서 분배관(10)에 의하면, 복수개의 분기관(20)을 결합하기 위한 결합공(11)이 분배관(10)의 측면부위에 단순히 펀칭 또는 드릴링 작업을 통해서 천공 형성됨에 따라, 종래와 같이 구멍의 천공 작업시 플랜지가 형성되도록 하는 것에 비하여, 작업성이 크게 개선되고 작업 효율이 향상되도록 할 수 있다.Therefore, according to the distribution pipe 10, as the coupling hole 11 for coupling the plurality of branch pipes 20 is formed by simply punching or drilling in the side portion of the distribution pipe 10, as in the prior art Compared to forming a flange when drilling a hole, workability can be greatly improved and work efficiency can be improved.

분기관(20)은, 분배관(10)의 결합공(11)에 결합되어 분배관(10)으로부터 냉매나 열매 즉, 유체가 분기되도록 하는 파이프부재로서, 원통 형상을 가지는 파이프부재가 소정의 길이로 절단된 후, 일단부가 스웨이징되어 축관이 연장된다.The branch pipe 20 is a pipe member that is coupled to the coupling hole 11 of the distribution pipe 10 so that a refrigerant or a fruit, that is, a fluid branch from the distribution pipe 10, and a pipe member having a cylindrical shape is After being cut to length, one end is swaged to extend the shaft tube.

분기관(20)은, 열전도율이 높은 금속, 보다 바람직하게는 동(銅) 재질을 가지는 것이 좋다. The branch pipe 20 is preferably made of a metal having a high thermal conductivity, more preferably a copper material.

한편, 분기관(20)은, 축관이 형성되는 파이프부재의 타단부에 결합공(11)과의 결합을 위하여 결합면(21)과 비딩(22)이 형성된다.Meanwhile, the branch pipe 20 has a coupling surface 21 and a bead 22 formed at the other end of the pipe member on which the shaft pipe is formed for coupling with the coupling hole 11.

여기서, 결합면(21)은, 분배관(10)의 결합공(11)이 곡면(11a)과 수평면(11b)을 가짐에 따라 전후 방향으로 요부(21a)를 가지고 좌우 방향으로 철부(21b)를 가지면서 만곡 형성된다.Here, the coupling surface 21, as the coupling hole 11 of the distribution pipe 10 has a curved surface 11a and a horizontal surface 11b, has a concave portion 21a in the front and rear direction and a convex portion 21b in the left and right direction It is curved while having.

이때, 결합면(21)의 요부(21a)와 철부(21b) 및 결합공(11)의 곡면(11a)과 수평면(11b)은, 상호간 대향 및 대면되도록 동일하게 만곡된 형상을 가지는 것이 좋다. At this time, it is preferable that the concave portion 21a and the convex portion 21b of the coupling surface 21 and the curved surface 11a and the horizontal surface 11b of the coupling hole 11 have the same curved shape so as to face each other and face each other.

또한, 비딩(22)은, 결합면(21)이 요부(21a)와 철부(21b)를 가지면서 만곡 형성됨에 따라 결합면(21)으로부터 소정 높이 이격된 위치의 외주면에 결합면(21)의 라인을 따라 소정의 두께로 돌출 형성된다.In addition, the beading 22, as the coupling surface 21 is curved while having the concave portion 21a and the convex portion 21b, the coupling surface 21 is formed on the outer circumferential surface spaced a predetermined height from the coupling surface 21. It is formed to protrude to a predetermined thickness along the line.

여기서, 결합면(21)으로부터 이격되는 비딩(22)의 높이는, 분배관(10)의 두께에 대응되는 것이 바람직하며, 이를 통하여, 비딩(22)이 결합공(11)의 외주면에 안착시 분기관(20)의 결합면(21) 단부가 분배관(10)의 두께를 벗어나 중공 내부로 노출되지 않도록 하는 것이 좋다.Here, it is preferable that the height of the beading 22 spaced apart from the coupling surface 21 corresponds to the thickness of the distribution pipe 10, and through this, when the beading 22 is seated on the outer peripheral surface of the coupling hole 11 It is good that the end of the coupling surface 21 of the engine 20 is not exposed to the hollow interior outside the thickness of the distribution pipe 10.

즉, 비딩(22)은, 결합면(21)의 요부(21a)와 철부(21b)를 따라 형성됨에 따라 결합공(11)에 결합면(21) 대면시 결합공(11) 외주면에 안착되어 결합공(11) 내부로 결합면(21)이 더 이상 삽입되지 않도록 할 수 있고, 이에, 결합 또는 분기 부분이 유체의 이동을 방해하지 않도록 할 수 있다.In other words, the beading 22 is formed along the concave portion 21a and the convex portion 21b of the coupling surface 21, so that when facing the coupling surface 21 in the coupling hole 11, the beading hole 11 is seated on the outer peripheral surface. The coupling surface 21 can be prevented from being inserted into the coupling hole 11 any more, and thus, the coupling or branching portion can be prevented from interfering with the movement of the fluid.

따라서 분기관(20)에 의하면, 분배관(10)의 결합공(11)에 결합면(21)의 대면시 비딩(22)이 결합공(11)의 외주면에 안착되는 상태를 가짐으로써, 결합공(11)의 곡면(11a)에는 결합면(21)의 철부(21b)가 대면되고 결합공(11)의 수평면(11b)에는 결합면(21)의 요부(21a)가 대면되는 상태를 안정적으로 유지할 수 있어 용접 작업을 용이하게 할 수 있다. Therefore, according to the branch pipe 20, by having a state in which the beading 22 is seated on the outer circumferential surface of the coupling hole 11 when the coupling surface 21 faces the coupling hole 11 of the distribution pipe 10, the coupling The convex portion (21b) of the coupling surface (21) faces the curved surface (11a) of the ball (11), and the concave portion (21a) of the coupling surface (21) faces to the horizontal surface (11b) of the coupling hole (11). As it can be maintained, welding work can be facilitated.

한편, 본 발명에 있어서, 분배관(10)과 분기관(20)의 중공 내주면에는 유체를 충돌 확산시킴과 동시에, 선회 와류를 발생시키는 유체선회용 요철면이 형성되는 것이 좋다. On the other hand, in the present invention, it is preferable that the hollow inner circumferential surfaces of the distribution pipe 10 and the branch pipe 20 are formed with an uneven surface for turning the fluid to generate a swirling vortex while colliding and diffusing the fluid.

이하, 본 발명의 바람직한 실시예에 따른 열교환기용 원통형 분배관과 분기관의 결합 구조체를 이용한 분배관과 분기관의 결합 방법에 대해 설명하면 다음과 같다.Hereinafter, a method of coupling a distribution pipe and a branch pipe using a coupling structure of a cylindrical distribution pipe and a branch pipe for a heat exchanger according to a preferred embodiment of the present invention will be described as follows.

먼저, 원통 형상을 가지는 분배관(10)을 제조하기 위하여 파이프부재가 소정길이로 절단된다.First, the pipe member is cut to a predetermined length to manufacture the distribution pipe 10 having a cylindrical shape.
