Description

열교환기용 냉매 분배기와 그 제조방법{Coolant Distributor for Heat Exchanger and Method for manufacturing the same}Refrigerant distributor for heat exchanger and its manufacturing method {Coolant Distributor for Heat Exchanger and Method for manufacturing the same}

본 발명은 열교환기의 각 냉매관에 냉매를 분배하여 주는 분배기에 관한 것으로, 특히 공기조화기 또는 냉장고 등의 열교환기의 각 냉매관에 냉매를 균일하게 분배함과 더불어 내부의 와류 발생에 의한 소음을 저감시킬 수 있도록 한 열교환기용 냉매 분배기를 제공함에 그 목적이 있다.The present invention relates to a distributor for distributing a refrigerant to each refrigerant pipe of the heat exchanger, and in particular, to uniformly distribute the refrigerant to each refrigerant pipe of the heat exchanger such as an air conditioner or a refrigerator, and to generate noise due to internal vortex generation. It is an object of the present invention to provide a refrigerant distributor for a heat exchanger that can reduce the heat sink.

일반적으로, 공기조화기 또는 냉장고 등은 열교환기를 이용하여 원하는 온도의 냉기 또는 온기를 생성하는 제품으로, 이러한 냉기 또는 온기를 생성하는 열교환기에는 냉매가 유동하는 복수개의 냉매관과 상기 냉매관에 부착되는 복수개의 방열핀이 구비되고, 열교환기의 각 냉매관은 하나의 분배기(distributor)에 연결되어 냉매를 공급받는다.In general, an air conditioner or a refrigerator is a product that generates cold or warm air at a desired temperature by using a heat exchanger. The heat exchanger that generates cold or warm air is attached to a plurality of refrigerant pipes through which refrigerant flows and the refrigerant pipe. A plurality of heat radiation fins are provided, and each refrigerant pipe of the heat exchanger is connected to one distributor to receive the refrigerant.

첨부된 도면의 도 1과 도 2는 상기와 같은 열교환기의 각 냉매관에 냉매를 분기하여 공급하는 종래의 분배기의 구조를 나타낸 것으로, 대략 원통형의 분배기 몸체(1)의 일단부에 냉매가 유입되는 유입구(2)가 형성되고, 이 유입구(2)의 반대편에는 각각의 냉매관(5)의 끝단부가 삽입되는 복수개의 관통공(3)이 형성되어 있다.1 and 2 of the accompanying drawings shows a structure of a conventional distributor for branching and supplying the refrigerant to each refrigerant pipe of the heat exchanger as described above, the refrigerant is introduced into one end of the approximately cylindrical distributor body (1) The inlet port 2 is formed, and a plurality of through-holes 3 into which the end portions of the respective refrigerant pipes 5 are inserted are formed at opposite sides of the inlet port 2.

그리고, 상기 분배기 몸체(1)의 내부에는 유입된 냉매로부터 이물질을 걸러내기 위한 그물망 구조의 메쉬(mesh)형 여과부재(4)가 설치된다.In addition, a mesh filtration member 4 having a mesh structure for filtering foreign substances from the refrigerant introduced into the distributor body 1 is installed.

따라서, 상기 분배기 몸체(1)의 유입구(2)를 통해 유입된 냉매는 메쉬형 여과부재(4)를 지나면서 이물질이 걸러진 다음, 각 관통공(3)에 고정된 냉매관(5) 끝단부를 통해 각각의 냉매관(5)으로 분배된다.Accordingly, the refrigerant introduced through the inlet port 2 of the distributor body 1 is filtered through the mesh filter member 4, and then the end of the refrigerant pipe 5 fixed to each through hole 3 is filtered. Through each refrigerant pipe (5).

그런데, 상기와 같은 종래의 분배기는 도 2에 도시된 것과 같이, 분배기 몸체(1) 내부로 유입된 냉매가 메쉬형 여과부재(4)에 의해 저항을 받으면서 메쉬형 여과부재(4) 전방에서 와류가 발생하게 되어 소음이 증가하게 되고, 각 냉매관을 통해 냉매가 균일하게 공급되지 못하여 열교환 효율을 저하시키는 문제가 있다.However, the conventional distributor as described above, as shown in FIG. 2, the refrigerant introduced into the distributor body 1 is vortexed in front of the mesh filter member 4 while being resisted by the mesh filter member 4. There is a problem that the noise is increased, the refrigerant is not uniformly supplied through each refrigerant pipe has a problem of lowering the heat exchange efficiency.

또한, 종래의 분배기는 제작과정에서 냉매관(5)이 몸체(1)에 수직하게 장착되지 못하고 비스듬하게 장착되는 경우가 많아 품질을 일정하게 유지하기가 곤란한 문제가 있다.In addition, the conventional distributor has a problem that it is difficult to maintain a constant quality because the refrigerant pipe 5 is often mounted obliquely rather than being mounted perpendicularly to the body 1 in the manufacturing process.

즉, 종래의 분배기는 냉매관(5)을 몸체(1)의 관통공(3)에 삽입한 후 작업자가 냉매관을 손으로 잡고 용접하여 고정시키게 되는데, 냉매관(5)을 몸체(1)에 삽입한 상태에서 냉매관을 지지하여 줄 수 있는 요소가 없으므로, 도 2에 도시된 것과 같이 냉매관(5)을 몸체(1)의 관통공(3) 외측에 용접할 때 냉매관(5)이 비뚤어지게 되는 것이다.That is, in the conventional distributor, the refrigerant pipe 5 is inserted into the through hole 3 of the body 1, and then the operator fixes the refrigerant pipe by hand and welds it to fix the refrigerant pipe 5 to the body 1. Since there is no element that can support the refrigerant pipe in the inserted state, the refrigerant pipe 5 when welding the refrigerant pipe 5 to the outside of the through hole 3 of the body 1 as shown in FIG. This is skewed.

이와 같이 냉매관(5)이 분배기에 비스듬하게 장착되면, 메쉬형 여과부재(4)를 통과한 냉매가 비스듬한 냉매관(5) 끝단부와 만나면서 이상 유동을 일으키거나 와류가 심하게 발생하여 내부에서 소음을 더욱 증가시키고, 공급 냉매의 불균일을심화시키게 된다.When the coolant tube 5 is mounted obliquely to the distributor as described above, the coolant passing through the mesh-like filtration member 4 meets the oblique end of the coolant tube 5, causing abnormal flow or vortices to be generated. Further increase and deepen the non-uniformity of the feed refrigerant.

이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 분배기 내부에서의 와류 발생을 최소화하여 소음 발생을 최소화하고 각 냉매관을 통해 냉매가 균일하게 공급될 수 있도록 한 열교환기용 냉매 분배기를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, to minimize the generation of vortex inside the distributor to minimize noise generation and to provide a refrigerant distributor for the heat exchanger to be supplied uniformly through each refrigerant pipe. Has its purpose.

이하, 첨부된 도면을 참조하여 본 발명에 따른 열교환기용 냉매 분배기의 바람직한 실시예들을 상세히 설명한다.Hereinafter, exemplary embodiments of a refrigerant distributor for a heat exchanger according to the present invention will be described in detail with reference to the accompanying drawings.

도 3 내지 도 5는 본 발명에 따른 열교환기용 냉매 분배기의 일 실시예를 나타낸 것으로, 중공의 원통형 분배기 몸체(11)의 일단부에 냉매가 유입되는 유입구(12)가 형성되고, 이 유입구(12) 반대편인 몸체(11)의 타단부에는 냉매관(15)이 삽입되는 복수개의 관통공(13)이 형성된다.3 to 5 show an embodiment of a refrigerant distributor for a heat exchanger according to the present invention, an inlet 12 through which a refrigerant is introduced into one end of the hollow cylindrical distributor body 11 is formed, and the inlet 12 At the other end of the body 11 opposite to the plurality of through holes 13 into which the refrigerant pipe 15 is inserted.

그리고, 상기 몸체(11) 내부의 중앙부에는 상기 관통공(13)이 형성된 부분에서부터 유입구(12) 쪽으로, 즉 몸체의 길이 방향으로 연장된 봉형상의 균등화부재(20)가 설치된다.In addition, the center portion inside the body 11 is provided with a rod-shaped equalization member 20 extending from the portion in which the through hole 13 is formed toward the inlet 12, that is, in the longitudinal direction of the body.

상기 균등화부재(20)는 관통공(13)이 형성된 몸체(11)의 끝단부에 고정되는 원반형의 고정부(21)와, 상기 고정부(21)의 중앙에서 유입구(12) 쪽으로 연장된 봉형상부(22)로 구성된다. 상기 고정부(21)에는 냉매관(15)이 삽통될 수 있도록 개구부(21a)가 형성되어 있다.The equalizing member 20 has a disk-shaped fixing portion 21 fixed to the end of the body 11, the through hole 13 is formed, and a rod-shaped extending from the center of the fixing portion 21 toward the inlet 12 It consists of an upper portion 22. The fixing portion 21 is formed with an opening 21a to allow the refrigerant pipe 15 to be inserted therethrough.

그리고, 상기 봉형상부(22)는 유입구(12)와 인접한 부분까지 형성되고, 유입구와 인접한 선단부는 냉매 유동을 부드럽게 유도하기 위하여 둥근 반구형으로 이루어진다.In addition, the rod-shaped portion 22 is formed up to a portion adjacent to the inlet 12, the front end portion adjacent to the inlet is made of a round hemispherical shape to induce the refrigerant flow smoothly.

상기 봉형상부(22)는 원형 단면 형상을 갖는 것이 바람직하나, 그 형상에 제한은 없으며, 도 6에 도시된 것과 같이 봉형상부(122)의 외주면에 길이 방향을 따라 복수개의 냉매관 가이드홈(123)을 형성할 수도 있다.Preferably, the rod-shaped portion 22 has a circular cross-sectional shape, but is not limited thereto. As illustrated in FIG. 6, the rod-shaped portion 22 has a plurality of refrigerant pipe guide grooves 123 along a length direction on an outer circumferential surface of the rod-shaped portion 122. ) May be formed.

또한, 도 7에 도시된 것과 같이, 봉형상부(222)가 전방의 유입구(12; 도 4참조) 쪽에서 후방의 관통공(13; 도 4참조) 쪽으로 갈수록 단면적이 점차적으로 증가하는 형태로 형성될 수도 있다.In addition, as shown in FIG. 7, the cross-sectional area of the rod-shaped portion 222 is gradually increased from the front inlet 12 (see FIG. 4) toward the rear through hole 13 (see FIG. 4). It may be.

도 8은 균등화부재의 다른 실시예를 나타낸 도면으로, 이 실시예의 균등화부재(320)는 몸체(11; 도 4참조)의 후단부에 고정되는 원반형의 고정부(321)가 봉상형상부(322)의 하단 모서리에 일체형으로 형성된다.8 is a view showing another embodiment of the equalizing member, in which the equalizing member 320 has a disc-shaped fixing portion 321 fixed to the rear end of the body 11 (see FIG. 4). It is formed integrally at the bottom edge of the).

상기와 같은 구조의 균등화부재(320)는 판상형 재료를 프레스 가공에 의해 용이하게 제조될 수 있는 이점을 갖는다.The equalization member 320 having the above structure has an advantage that the plate-shaped material can be easily manufactured by press working.

한편, 전술한 실시예들의 설명에서는 상기 균등화부재들이 원반형의 고정부를 구비하여, 상기 고정부가 몸체(11)의 끝단에 고정되는 것으로 설명하였으나, 이와는 다르게 상기와 같은 고정부없이 봉형상을 한 봉형상부가 바로 몸체의 끝단부에 일체로 고정될 수도 있을 것이다.On the other hand, in the description of the embodiments described above, the equalizing members have a disc-shaped fixing part, so that the fixing part is fixed to the end of the body 11, but differently from the bar shape without the fixing part as described above The upper portion may be integrally fixed to the end of the body immediately.

다시 도 4에 도시된 냉매 분배기를 참조하여 상기와 같이 구성된 냉매 분배기의 작용에 대해 설명하면 다음과 같다.Referring to the refrigerant distributor shown in FIG. 4 again, the operation of the refrigerant distributor configured as described above is as follows.

일측의 유입구(12)를 통해 몸체(11) 내부로 유입된 냉매는, 유입구(12)의 바로 후방에 균등화부재(20)의 봉형상부(22)가 위치하고 있기 때문에 상기 봉형상부(22)를 중심으로 외측으로 퍼지며 봉형상부의 외주부를 따라 유동하게 되고, 이어서 봉형상부(22)의 외측에 배치되는 각 냉매관(15)으로 유입되어 외부로 배출된다.The refrigerant introduced into the body 11 through the inlet 12 on one side is centered on the rod-shaped part 22 because the rod-shaped part 22 of the equalizing member 20 is located immediately behind the inlet 12. It spreads outward and flows along the outer circumferential portion of the rod-shaped portion, and then flows into each refrigerant pipe 15 disposed outside the rod-shaped portion 22 and discharged to the outside.

이와 같이, 상기 유입구(12)를 통해 유입된 냉매 유동은 상기 균등화부재(20)와 만나는 부분에서 약간의 와류가 생성될 뿐 몸체(11) 내부에서 와류 생성이 최소화되면서 각 냉매관으로 유입된다.As such, the refrigerant flow introduced through the inlet 12 is introduced into each refrigerant pipe while only a slight vortex is generated at a portion that meets the equalization member 20, while vortex generation is minimized inside the body 11.

한편, 도 9를 참조하여 상기와 같이 구성된 본 발명의 냉매 분배기의 제조방법을 설명하면 다음과 같다.Meanwhile, referring to FIG. 9, a manufacturing method of the refrigerant distributor according to the present invention configured as described above is as follows.

먼저, 일단부가 개방되고 타단부에 복수개의 관통공(13)이 형성된 원통형 몸체(11)를 준비하여, 상기 몸체(11)의 개방된 부분을 통해 균등화부재(20)를 삽입한다. 이 때, 균등화부재(20)의 고정부(21)의 직경은 몸체(11)의 내경보다 약간 작은 크기를 가져 상기 고정부(21)가 몸체(11)의 내벽면에 거의 연접하게 된다.First, a cylindrical body 11 having one end open and a plurality of through holes 13 formed at the other end thereof is prepared, and the equalization member 20 is inserted through an open portion of the body 11. At this time, the diameter of the fixing portion 21 of the equalizing member 20 has a size slightly smaller than the inner diameter of the body 11 so that the fixing portion 21 is almost in contact with the inner wall surface of the body 11.

이러한 상태에서 상기 몸체(11)의 개방된 끝단부를 축관하여 유입구(12)를 형성한다.In this state, the inlet 12 is formed by axially opening the open end of the body 11.

이어서, 상기 관통공(13)이 형성된 몸체(11) 끝단부를 축관하여 균등화부재(20)의 고정부(21)를 몸체(11) 내벽면에 완전히 밀착시켜 고정되게 한다.Subsequently, the end portion of the body 11 in which the through hole 13 is formed is axially fixed so that the fixing part 21 of the equalizing member 20 is completely adhered to the inner wall of the body 11.

끝으로 상기 각 관통공(13)을 통해 냉매관(15)을 삽입한 다음 용접하여 고정시키면 냉매 분배기의 제작이 완료된다.Finally, the refrigerant pipes 15 are inserted through the through holes 13 and then welded to fix the refrigerant distributors.

따라서, 본 발명에 의하면 냉매 분배기의 제조시 냉매관(15)을 분배기 몸체(11)에 고정시키는 작업을 제외하고는 전혀 용접 작업을 수행할 필요가 없으므로 매우 간단하고 용이하게 냉매 분배기를 제조할 수 있는 이점을 얻게 된다.Therefore, according to the present invention, there is no need to perform welding at all except for fixing the refrigerant pipe 15 to the distributor body 11 in the manufacture of the refrigerant distributor, so that the refrigerant distributor can be manufactured very simply and easily. You have the advantage.

또한, 상기 균등화부재(20)의 봉형상부(22)가 각 냉매관(15) 사이에 배치되는 구조이므로, 냉매관(15)을 몸체(11) 내에 삽입하여 고정할 때 상기 봉형상부(22)가 냉매관(15)을 안내하는 역할을 하거나 지지하는 역할을 하게 되므로 냉매관이 비뚤어지지 않고 수직하게 고정될 수 있다.In addition, since the rod-shaped portion 22 of the equalizing member 20 is disposed between the respective refrigerant pipes 15, the rod-shaped portion 22 when the refrigerant pipe 15 is inserted into and fixed to the body 11. Since it serves to guide or support the refrigerant pipe 15, the refrigerant pipe can be fixed vertically without being skewed.

이상에서와 같이 본 발명에 따르면, 냉매 분배기의 몸체 내부로 유입되는 냉매가 균등화부재에 의해 외측으로 부드럽게 분배되며 유동하게 되므로 몸체 내부에서 와류 생성이 최소화되면서 냉매관 내로 유입될 수 있게 된다. 따라서, 와류 발생에 의한 소음 발생을 현저히 감소시킬 수 있다.As described above, according to the present invention, since the refrigerant flowing into the body of the refrigerant distributor is smoothly distributed and flows outward by the equalizing member, the refrigerant can be introduced into the refrigerant pipe while minimizing the generation of vortex inside the body. Therefore, it is possible to significantly reduce the noise generated by the vortex generation.

또한, 본 발명의 냉매 분배기 제조시 용접 작업이 거의 필요없으므로 제작이용이하다.In addition, since the welding operation is hardly required in manufacturing the refrigerant distributor of the present invention, it is easy to manufacture.

이와 더불어, 냉매관을 분배기 내부에 삽입하여 고정할 때 균등화부재가 냉매관을 안내 및 지지하는 역할을 하므로 냉매관이 분배기에 비뚤어지지 않고 수직하게 장착될 수 있으며, 따라서 분배기 내부에서의 와류 발생을 더욱 억제할 수 있게 된다.In addition, since the equalizing member guides and supports the refrigerant pipe when the refrigerant pipe is inserted into the distributor and fixed, the refrigerant pipe can be mounted vertically without being skewed to the distributor, thus preventing the generation of vortex inside the distributor.
