Description
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 있으며, 제작이 용이하도록 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 eddy currents. The purpose of the present invention is to provide a refrigerant distributor for a heat exchanger that can reduce the pressure and make the production easy.
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 못하는 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. The noise is increased and there is a problem that the refrigerant is not uniformly supplied through each refrigerant pipe.
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 불균일을 심화시키게 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 and causes abnormal flow or vortices to be generated. And further increase the non-uniformity of the feed refrigerant.
또한, 종래의 분배기는 양단이 개방된 원통형의 분배기 몸체(1)의 일단부를 축관하여 폐쇄시키고, 이 부분에 펀칭작업을 통해 냉매관(5)이 삽입되는 복수개의 관통공을 형성한 다음, 메쉬형 여과부재(4)를 내부에 삽입하여 장착한 후, 반대편을 축관하여 유입구(2)를 형성하며, 이어서, 상기 관통공(3)을 통해 냉매관(5)의 일단부를 삽입한 후 용접작업을 통해 고정시키는 과정으로 제작되는 바, 제작 과정이 다소 복잡한 문제도 있다.In addition, the conventional distributor is closed by axially closing one end of the cylindrical distributor body 1, which is open at both ends, and forms a plurality of through holes into which the refrigerant pipe 5 is inserted through a punching operation, and then meshes. After inserting and inserting the type filtration member 4 therein, the inlet port 2 is formed by condensing the opposite side, and then one end of the refrigerant pipe 5 is inserted through the through hole 3, and then a welding operation is performed. It is produced by the process of fixing through the bar, there is also a somewhat complicated problem in the production process.
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.
본 발명의 다른 목적은 냉매관이 분배기에 장착될 때 어긋나거나 비틀어지지 않고 수직하게 장착될 수 있도록 함과 더불어 제작이 용이하도록 한 열교환기용 냉매 분배기의 제조방법을 제공하는 것이다.Another object of the present invention is to provide a method of manufacturing a refrigerant distributor for a heat exchanger, which allows the refrigerant pipe to be vertically mounted without being displaced or twisted when mounted in the distributor.
상기와 같은 목적을 달성하기 위한 본 발명의 한 관점에 따르면, 냉매가 유동하는 중공의 몸체와; 상기 몸체의 일단부에 형성되어 냉매가 유입되는 입구부와; 상기 몸체의 타단부에 일렬로 연이어서 일체로 형성되어 열교환기의 각 냉매관들의 끝단부가 삽입되어 고정되는 복수개의 배출구를 포함하여 구성된 열교환기용 냉매 분배기를 제공한다.According to an aspect of the present invention for achieving the above object, the hollow body through which the refrigerant flows; An inlet formed at one end of the body to allow refrigerant to flow therein; It provides a refrigerant distributor for a heat exchanger comprising a plurality of outlets which are formed in a row in the other end of the body and integrally formed so that the end of each of the refrigerant pipes of the heat exchanger is inserted and fixed.
본 발명의 다른 한 관점에 따르면, 상기 열교환기용 냉매 분배기를 제조하는 방법으로, 몸체의 일단부를 축관하여 유입부를 형성하는 단계; 몸체의 타단부를 프레스 가공하여 복수개의 배출구를 일렬로 연이어서 형성하는 단계; 및 상기 각 배출구에 각 냉매관의 끝단부를 삽입하여 고정시키는 단계를 포함하여 구성된 냉매 분배기 제조방법이 제공된다.According to another aspect of the present invention, a method for manufacturing the refrigerant distributor for the heat exchanger, comprising the step of forming an inlet by condensing one end of the body; Pressing the other end of the body to form a plurality of outlets connected in series; And inserting and fixing an end of each refrigerant pipe into each of the outlets to provide a refrigerant distributor manufacturing method.
이하, 본 발명에 따른 열교환기의 냉매 분배기의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, a preferred embodiment of a refrigerant distributor of 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 발명의 냉매 분배기의 구조를 나타낸 도면으로, 중공의 분배기 몸체(11)의 일단부에는 냉매가 유입되는 유입구(12)가 형성되고, 이 유입구(12) 반대편인 분배기 몸체(11)의 타단부에는 원형 단면을 갖는 기다란 관형태의 복수개의 배출구(13)가 일렬로 연이어서 일체로 형성된다. 3 to 5 is a view showing the structure of the refrigerant distributor of the present invention, one end of the hollow distributor body 11 is formed with an inlet 12 through which the refrigerant is introduced, the distributor body opposite the inlet 12 At the other end of (11), a plurality of outlets 13 in the form of elongated tubes having a circular cross section are formed in a row and integrally formed.
상기 배출구(13)는 냉매관(15)의 직경과 거의 같은 크기의 직경을 갖도록 형성되어, 이들 각 배출구(13)에 열교환기(미도시)의 냉매관(15)들의 끝단부가 삽입된 후 용접 등에 의해 고정되는데, 여기서 각 냉매관(15)의 끝단은 각 배출구(13) 외측으로 튀어나오지 않고 내측에 위치되도록 하는 것이 유로 저항을 줄이는데 바람직하다. The outlet 13 is formed to have a diameter approximately the same size as the diameter of the refrigerant pipe 15, the end of the refrigerant pipe 15 of the heat exchanger (not shown) is inserted into each of the outlet 13 is welded And the like, wherein the end of each refrigerant pipe 15 is located inward instead of protruding outward from each outlet 13.
그리고, 도 4에 상세히 도시된 것처럼, 상기 분배기 몸체(11)는 유입구(12)의 후단에서부터 소정 길이(ℓb)만큼 단면적이 확대되는 확장부(111)와, 상기 확장부(111)의 후단에서부터 배출구(13)의 전단까지 단면적이 점차적으로 줄어드는 테이퍼부(112)로 이루어져 전체적으로 유선형으로 이루도록 되어 있는데, 여기서 상기 테이퍼부(112)는 유로 저항을 최소화시킬 수 있도록 높이는 점차적으로 작아지지만 그 폭은 점차적으로 약간씩 증가하는 형태를 갖는다.And, as shown in detail in FIG. 4, the distributor body 11 is an extension 111 which is enlarged in cross-sectional area by a predetermined length l b from the rear end of the inlet 12, and the rear end of the expansion 111 From the front end of the outlet 13 to the tapered portion 112 is gradually reduced in cross section is made to form a streamline, where the tapered portion 112 is gradually reduced in height so as to minimize the flow resistance but the width thereof is Gradually slightly increasing form.
따라서, 일측의 유입구(12)를 통해 유입된 냉매는 분배기 몸체(11)가 유입구(12) 쪽에서 배출구(13) 쪽으로 유선형으로 되어 있으므로 배출구(13)를 향해 부드럽게 퍼지면서 진행하게 되므로 와류를 거의 발생시키지 않고 각각의 배출구(13) 쪽으로 비교적 균일하게 유동하게 된다. Therefore, the refrigerant introduced through the inlet 12 on one side has a streamlined flow toward the outlet 13 since the distributor body 11 is streamlined toward the outlet 13 from the inlet 12 so that almost any eddy current is generated. Relatively uniformly flow toward each outlet (13).
상기 배출구(13)의 입구에 도달한 냉매는 각 배출구(13)에 고정된 냉매관(15)으로 유입된다.The refrigerant reaching the inlet of the outlet 13 is introduced into the refrigerant pipe 15 fixed to each outlet 13.
한편, 상기와 같은 본 발명의 냉매 분배기는 다음과 같이 제작된다.On the other hand, the refrigerant distributor of the present invention as described above is manufactured as follows.
도 6에 도시된 바와 같이, 양단부가 개방된 대략 원통형의 분배기 몸체(11)를 준비한 다음, 이 분배기 몸체(11)의 일단부를 축관하여 유입구(12)를 형성하고, 분배기 몸체(11)의 타단부를 프레스 가공하여 복수개의 배출구(13)를 일렬로 연이어서 일체로 형성한다. 이 때, 상기 분배기 몸체(11)는 별도의 가공을 하지 않아도 상기 축관 및 프레스 공정을 통해 자연스럽게 도면에 도시한 형상을 갖게 된다.As shown in FIG. 6, a substantially cylindrical distributor body 11 having open ends is prepared, and then one end of the distributor body 11 is formed to form an inlet 12, and the other of the distributor body 11 is formed. The end portion is pressed to form a plurality of outlets 13 in a row and integrally formed. At this time, the distributor body 11 has a shape naturally shown in the drawings through the shaft tube and the pressing process without any additional processing.
상기와 같이 분배기의 형태가 갖추어지면, 상기 각 배출구(13)에 냉매관(15)의 끝단부를 삽입한 후, 배출구(13) 후단의 외주연부와 냉매관(15)을 용접에 의해 고정시키게 된다.When the shape of the distributor is provided as described above, the end of the refrigerant pipe 15 is inserted into each of the outlets 13, and then the outer circumferential edge of the rear end of the outlet 13 and the refrigerant pipe 15 are fixed by welding. .
상술한 것처럼 상기 각 배출구(13)들은 냉매관(15)에 상응하는 형태를 가지면서 나란하게 분지되어 있으므로, 상기 배출구(13)에 냉매관(15)을 삽입시킬 때 냉매관(15)들은 각 배출구(13)들의 안내를 받으면서 어긋나지 않고 서로 나란하게 고정될 수 있게 된다.As described above, each outlet 13 is branched side by side while having a shape corresponding to the refrigerant pipe 15, and thus, when the refrigerant pipe 15 is inserted into the outlet 13, the refrigerant pipes 15 are each branched. While being guided by the outlets 13, they can be fixed in parallel with each other without being misaligned.
한편, 다시 도 4를 참조하면, 상기와 같이 구성된 본 발명의 분배기는 상기 배출구(13)의 길이(ℓa)가 유입구(12)를 제외한 분배기의 전체 길이(ℓt)의 1/4 내지 3/4 범위에 있는 것이 바람직한데, 만약 배출구(13)의 길이(ℓa)가 분배기 전체 길이(ℓt)의 1/4 보다 작을 경우에는 용접 작업시 용접물이 내부로 유입될 가능성이 크게 되고, 배출구(13)의 길이(ℓa)가 분배기 전체 길이(ℓt)의 3/4을 넘게 되면 프레스 가공이 어려울 뿐만 아니라 배출구(13) 입구에서 와류가 많이 생성되어 유동 소음이 증가하게 된다.Meanwhile, referring again to FIG. 4, the dispenser of the present invention configured as described above has a length (l a ) of the outlet (13) of 1/4 to 3 of the total length (L t ) of the distributor except for the inlet (12). It is preferably in the range of / 4, if the length (l a ) of the outlet 13 is less than 1/4 of the total length (L t ) of the distributor, there is a high possibility that the weld is introduced into the inside during the welding operation, When the length (l a ) of the outlet 13 exceeds 3/4 of the total length (l t ) of the distributor, not only is it difficult to press, but also many vortices are generated at the inlet 13 of the outlet 13, thereby increasing the flow noise.
한편, 상기 분배기를 통해서 냉매관으로 분배되는 냉매로부터 이물질을 걸러내는 여과부재는 분배기의 몸체 내부에 설치될 수도 있으나, 이 경우 와류를 발생시킬 수 있으므로 분배기의 유입구(12) 외측 또는 유입구(12) 내에 설치하는 것이 바람직하다. On the other hand, the filtration member for filtering foreign matter from the refrigerant distributed through the distributor to the refrigerant pipe may be installed inside the body of the distributor, in this case, because it may generate vortex, outside or inlet 12 of the inlet 12 of the distributor It is preferable to install inside.
이상에서와 같이 본 발명에 따르면, 분배기의 입구를 통해 유입되는 냉매가 유선형의 분배기 몸체를 통해 배출구 쪽으로 원활히 진행할 수 있게 되므로 분배기 내부에서 와류가 거의 발생하지 않게 되어 유동 소음이 줄어들고, 각 냉매관으로 냉매가 비교적 균일하게 공급될 수 있게 되어 열교환기의 전체적인 성능을 향상시킬 수 있게 된다.As described above, according to the present invention, since the refrigerant flowing through the inlet of the distributor can smoothly proceed toward the outlet through the streamlined distributor body, almost no vortex occurs in the distributor, thereby reducing the flow noise, and into each refrigerant pipe. The refrigerant can be supplied relatively uniformly, thereby improving the overall performance of the heat exchanger.
또한, 축관 - 프레스 가공 - 용접의 간단한 공정에 의해 분배기가 제작되므로 기존에 비하여 제작 공정이 대폭 축소됨과 더불어, 냉매관 형태에 상응하여 미리 형성된 각 배출구에 냉매관이 삽입되어 고정되므로 냉매관이 어긋나거나 비뚤어지지 않고 원하는 방향으로 고정될 수 있게 되고, 이에 따라 분배기 내부에서 와류 및 이상 유동 발생을 더욱 억제할 수 있게 된다.In addition, since the distributor is manufactured by a simple process of shaft tube-pressing-welding, the manufacturing process is greatly reduced compared to the conventional one, and the refrigerant tube is inserted and fixed in each outlet formed in advance according to the shape of the refrigerant tube. It is possible to be fixed in a desired direction without being undistorted or skewed, thereby further suppressing the generation of eddy currents and abnormal flow in the distributor.
