Description

냉장고 방열판{A HEAT SINK OF REFRIGERATOR}Refrigerator Heat Sink {A HEAT SINK OF REFRIGERATOR}

본 고안은 냉장고의 방열판에 관한 것으로, 특히, 방열 파이프의 열 방출이 용이하도록 방열 파이프와 긴밀하게 밀착되어 고정되는 구조를 가지는 냉장고의 방열판에 관한 것이다.The present invention relates to a heat sink of the refrigerator, and more particularly, to a heat sink of the refrigerator having a structure that is in close contact with and fixed to the heat dissipation pipe to facilitate heat dissipation of the heat dissipation pipe.

일반적으로 냉장고의 냉동 사이클은 냉매가 냉매관을 통해 서로 연결된 압축기, 응축기, 팽창 밸브, 증발기를 순차적으로 지나면서 압축, 응축, 팽창, 증발됨으로써 이루어진다. 즉, 냉매는 압축기에서 고온 고압으로 압축되고 응축기에서 그 압축된 냉매의 열이 냉장고 외부로 방출되며, 이때 냉각된 냉매는 팽창 밸브를 통해 팽창하여 증발기에서 냉장고 고내의 열을 흡수하면서 기화한다. 따라서, 통상적으로 증발기 또는 냉각 파이프는 냉장고 고내측의 열을 흡수하도록 냉장고 고내 측에 설치되며, 응축기 또는 방열 파이프는 냉장고 외부에 노출되게 설치된다.In general, a refrigeration cycle of a refrigerator is achieved by sequentially compressing, condensing, expanding, and evaporating refrigerant passing through a compressor tube, a condenser, an expansion valve, and an evaporator connected to each other through a refrigerant pipe. That is, the refrigerant is compressed to a high temperature and high pressure in the compressor and the heat of the compressed refrigerant is discharged to the outside of the refrigerator in the condenser, where the cooled refrigerant expands through an expansion valve and vaporizes while absorbing heat in the refrigerator compartment in the evaporator. Therefore, the evaporator or the cooling pipe is typically installed inside the refrigerator to absorb heat from the inside of the refrigerator, and the condenser or heat dissipation pipe is installed to be exposed to the outside of the refrigerator.

도 1은 방열파이프에 고정된 종래의 냉장고 방열판를 도시하며, 도 2는 도 1에 도시된 방열 판의 부분 단면을 도시한다.1 shows a conventional refrigerator heat sink fixed to a heat dissipation pipe, and FIG. 2 shows a partial cross section of the heat dissipation plate shown in FIG. 1.

방열판(2)은 방열 파이프(10)가 변형되는 것을 방지하고 외부 충격에 의해 파손되는 것을 방지하도록 금속재로 된 평판으로 제공된다. 도 2를 참조하면, 방열파이프(10)는 열 방출이 용이하도록 방열판(2)의 일측면에 접하게 위치되어 고정수단에 의해 고정된다. 상기 고정 수단은 방열파이프(10)의 열이 방열판(2)으로 열 전도에 의해 전달되도록 통상적으로 접착테이프(30)로 제공된다.The heat sink 2 is provided with a flat plate made of metal to prevent the heat pipe 10 from being deformed and broken by external impact. Referring to FIG. 2, the heat dissipation pipe 10 is positioned in contact with one side of the heat dissipation plate 2 so as to facilitate heat dissipation and is fixed by the fixing means. The fixing means is typically provided to the adhesive tape 30 so that the heat of the heat radiation pipe 10 is transferred to the heat sink 2 by heat conduction.

그러나, 방열판(2)이 방열파이프(10)에 접착테이프(30)에 의해 고정됨으로써, 방열판 또는 방열 파이프가 변형된 경우, 또는 작업자가 접착테이프를 긴밀하게 밀착하여 상기 방열판과 방열 파이프를 고정하지 않은 경우에는 상기 방열판과 방열 파이프 사이에 들뜸이 발생하였다. 따라서, 방열 파이프의 열은 방열판으로 열전도에 의해 전달되지 않고 대류에 의해 공기 중으로 열 분산됨으로써, 열 방출 효율을 떨어뜨려 냉장고의 냉각 성능 또한 낮아지는 문제가 있었다.However, when the heat sink 2 is fixed to the heat radiation pipe 10 by the adhesive tape 30, the heat sink or the heat radiation pipe is deformed, or the operator does not closely adhere the adhesive tape to fix the heat sink and the heat radiation pipe. If not, a lift occurred between the heat sink and the heat dissipation pipe. Therefore, the heat of the heat dissipation pipe is not transmitted by the heat conduction to the heat sink, but heat dissipates into the air by convection, thereby lowering the heat dissipation efficiency and reducing the cooling performance of the refrigerator.

따라서, 본 고안은 방열 파이프이 열이 방열판으로 전도에 의해 전달되도록방열판과 방열 파이프가 변형된 경우에도 서로 밀착될 수 있는 구조를 가짐으로써 냉장고의 냉각 성능을 향상시킬 수 있는 방열판을 제공하는 것을 목적으로 한다.Accordingly, the present invention has an object of providing a heat sink that can improve the cooling performance of the refrigerator by having a structure that can be in close contact with each other even if the heat sink and the heat pipe is deformed so that the heat is transferred to the heat sink by conduction to the heat sink. do.

상기된 바와 같은 목적을 달성하도록 본 고안에 따른 방열판은 방열파이프를 접촉 지지하도록 평탄면을 갖는 평탄부와, 상기 방열 파이프를 측면 지지하도록 상기 평탄부의 평탄면으로부터 수직 연장하여 형성된 복수개의 지지대를 포함하여 구성된다.In order to achieve the object as described above, the heat sink according to the present invention includes a flat portion having a flat surface to contact and support the heat dissipation pipe, and a plurality of supports formed to extend vertically from the flat surface of the flat portion to laterally support the heat dissipation pipe. It is configured by.

이하에서는 본 고안에 따른 상세한 구성을 도면을 참조하여 더욱 상세하게 설명한다.Hereinafter, a detailed configuration according to the present invention will be described in more detail with reference to the drawings.

도 3은 본 고안에 따라 방열파이프(10)에 장착된 방열판(20)을 도시하며, 도 4는 방열판(20)과 방열파이프(10)의 결합 상태를 도시하기 위한 단면도이다.3 illustrates a heat sink 20 mounted to the heat dissipation pipe 10 according to the present invention, and FIG. 4 is a cross-sectional view illustrating a coupling state of the heat dissipation plate 20 and the heat dissipation pipe 10.

방열 파이프(10)는 제 1 직선부와, 상기 제 1 직선부의 단부가 굽혀져 형성된 제 1 곡선부, 상기 제 1곡선부의 단부가 직선으로 연장하여 형성되어 상기 제 1 직선부로부터 평행하게 이격된 제 2 직선부, 상기 제 2 직선부의 단부가 굽혀져 형성된 제 2곡선부를 각각 포함하여 냉장고 고내측에 설치된 냉각 파이프에서 흡수된 열에 의해 가열된 냉매가 내측을 통과한다. 또한, 상기 방열 파이프(10)는 냉장고 후면에 장착된 상태에서 열방출이 용이하도록 방열판(20)이 제공된다.The heat dissipation pipe 10 includes a first straight portion, a first curved portion formed by bending an end portion of the first straight portion, and an end portion of the first curved portion extending in a straight line to be spaced apart in parallel from the first straight portion. The refrigerant heated by the heat absorbed by the cooling pipe installed inside the refrigerator, including the second straight portion and the second curved portion formed by bending the end portion of the second straight portion, respectively, passes through the inside. In addition, the heat dissipation pipe 10 is provided with a heat dissipation plate 20 to facilitate heat dissipation in a state of being mounted on the rear of the refrigerator.

방열판(20)은 평탄부(22)로부터 돌출하여 형성된 복수개의 지지대(21)가 서로 평행하게 제공된다. 각각의 지지대들(21)은 방열파이프의 각각의 직선부들(10a)을 측면 지지하도록 상기 직선부들이 서로 이격된 폭과 동일한 폭으로 이격되게 배치된다.The heat sink 20 is provided with a plurality of supports 21 formed to protrude from the flat portion 22 in parallel with each other. Each of the supports 21 is disposed to be spaced apart from each other by the same width as the spaced apart from each other so as to laterally support the respective straight portions 10a of the heat dissipation pipe.

도 4를 참조하면, 방열 파이프(10)는 지지대(21)와 평탄부(22)에 각각 접촉하도록 테이프(30)에 의해 고정된다. 따라서, 상기 방열파이프는 2 점에 접촉한 상태, 즉, 지지대와 평탄부에 각각 접촉한 상태에서 테이프(30)에 의해 고정된다. 또한, 방열 파이프가 변형되어 평탄부(22)에 접촉하지 못한 경우에도, 즉 방열 파이프(10)와 평탄부(22) 사이에 들뜸현상이 발생한 경우에도 적어도 지지대의 측면과 접촉한다. 더욱이, 상기 지지대(21)는 그 높이가 방열 파이프의 직경보다 작게 제공되며 가장 바람직하게는 파이프의 반경과 동일한 높이로 제공된다. 따라서, 테이프(30)는 그 양단부가 평탄부(22)와 지지대(21)에 각각 고정되고 중간부가 상기 평탄부와 지지대로부터 돌출하게 위치된 방열 파이프(10)에 고정됨으로써, 테이프 접착력의 작용 방향이 방열 파이프의 들뜸 방향과 반대 방향으로 제공되어 방열 파이프가 변형되어 평탄부로부터 이격되는 것을 차단한다.Referring to FIG. 4, the heat dissipation pipe 10 is fixed by the tape 30 to be in contact with the support 21 and the flat part 22, respectively. Therefore, the heat dissipation pipe is fixed by the tape 30 in contact with two points, that is, in contact with the support and the flat portion, respectively. In addition, even when the heat dissipation pipe is deformed and does not come into contact with the flat part 22, that is, even when a lifting phenomenon occurs between the heat dissipation pipe 10 and the flat part 22, at least the side of the support is in contact with the support. Moreover, the support 21 is provided at a height smaller than the diameter of the heat dissipation pipe and most preferably at the same height as the radius of the pipe. Therefore, the tape 30 is fixed at both ends thereof to the flat portion 22 and the support 21, and the middle portion thereof is fixed to the heat dissipation pipe 10 positioned to protrude from the flat portion and the support. The heat dissipation pipe is provided in a direction opposite to the lifting direction of the heat dissipation pipe to prevent the heat dissipation pipe from being deformed and spaced apart from the flat portion.

따라서, 본 고안은 상기된 바와 같이 방열 파이프가 평탄부로부터 들뜨지 않으며 방열판의 평탄부와 지지대에 적어도 2 지점에서 접촉하므로 방열파이프의 열은 전도에 의해 방열판으로 전달되어 열방출이 용이하여 냉장고의 냉각 성능이 향상되는 장점이 있다.Therefore, the present invention, as described above, since the heat dissipation pipe is not lifted from the flat portion and contacts the flat portion of the heat sink and the support at at least two points, the heat of the heat dissipation pipe is transferred to the heat sink by conduction, so that the heat is easily released, thereby cooling the refrigerator. This has the advantage of improving performance.
