본 고안은 열교환기에 관한 것으로, 특히 냉장고나 공기조화기 등에 장착되는 열교환기의 구조를 개선하여 보다 소형화가 가능하도록 한 것이다.The present invention relates to a heat exchanger, and in particular to improve the structure of the heat exchanger mounted on a refrigerator or an air conditioner to enable a more compact.
일반적으로 냉장고나 공기조화기는 냉동사이클을 수행함으로써 식품을 냉동 또는 냉장상태로 보관하거나 공기조화를 실현한다. 이러한 냉장고나 공기조화기가 수행하는 냉동사이클은 냉매의 상태변화를 이용하여 압축, 응축, 팽창, 증발과정을 연속적으로 이룸으로써 완성된다. 냉동사이클중 응축이나 증발과정은 통상적으로 핀형 열교환기에 의해 수행된다.Generally, a refrigerator or an air conditioner performs a refrigeration cycle to store food in a frozen or refrigerated state or to realize air conditioning. A refrigeration cycle performed by such a refrigerator or an air conditioner is completed by continuously performing compression, condensation, expansion, and evaporation processes using a change of state of a refrigerant. Condensation or evaporation during the refrigeration cycle is usually carried out by a fin heat exchanger.
제1도는 응축기로서 역할을 하는 핀형 열교환기(1)가 장착된 냉장고(2)를 도시한 것이다. 이는 냉장고의 후벽등에 장착되어 자연대류에 의해 열교환을 수행하는 통상의 응축기와는 달리 냉장고(2)의 기계실(3)에 장착되어 압축기(4)를 냉각시키기 위한 냉각용 팬(5)을 이용하여 강제대류로 열교환을 수행하는 콤팩트형 열교환기를 나타낸 것이다. 이와 같이 콤팩트형 열교환기는 냉장고(2)의 기계실(3)에 장착되어 압축기(4)에서 토출된 고압의 냉매가스를 주위공기와의 열교환을 통해 응축시킨다.1 shows a refrigerator 2 equipped with a fin heat exchanger 1 which serves as a condenser. Unlike a conventional condenser mounted on the rear wall of the refrigerator and performing heat exchange by natural convection, it is mounted in the machine room 3 of the refrigerator 2 by using a cooling fan 5 for cooling the compressor 4. It shows a compact heat exchanger performing heat exchange by forced convection. Thus, the compact heat exchanger is mounted in the machine room 3 of the refrigerator 2 to condense the high-pressure refrigerant gas discharged from the compressor 4 through heat exchange with the ambient air.
제2도에는 이러한 종래의 핀형 열교환기의 구조를 나타내 보인 사시도이다,. 이에 도시한 바와 같이, 종래의 핀형 열교환기(1)는 그 내부를 냉매가 흐르는 파이프(1a)가 소정간격으로 적층 배열된 전열판(1b)을 관통하여 일체로 구성된 것으로, 파이프(1a)의 각 행간 간격과 각 열간 간격이 각각 동일한 구조이다. 이러한 파이프는 다수의 U형 밴딩을 통해 다수의 행과 열을 구성하는데, 파이프의 직경과 밴딩공법상 제품 전체의 크기를 감소시키는 데 한계가 있었다. 즉 파이프는 소정크기의 직경을 가지고 밴딩을 하기 위해서는 지그 등을 사용해야 하기 때문에 파이프를 도면보다 더 작은 곡률로 밴딩시킬 수 없었고 이에 따라 열교환기의 전체크기를 줄이는데 한계가 있었다. 따라서 동일한 성능을 가지면서도 냉장고 기계실과 같은 좁은 공간에 장착하기 위한 소형 열교환기의 개발이 요구되었다.2 is a perspective view showing the structure of such a conventional fin heat exchanger. As shown in the drawing, the conventional fin-type heat exchanger 1 is integrally formed through the heat transfer plates 1b in which the pipes 1a through which refrigerant flows are stacked and arranged at predetermined intervals. The spacing between rows and columns is the same. These pipes consist of a plurality of rows and columns through a plurality of U-shaped bandings, which have limitations in reducing the diameter of the pipe and the overall size of the product due to the bending method. That is, because the pipe must be a jig or the like in order to bend with a diameter of a predetermined size, the pipe could not be bent to a curvature smaller than the drawing, thereby limiting the overall size of the heat exchanger. Therefore, the development of a small heat exchanger having the same performance but for mounting in a narrow space such as a refrigerator machine room was required.
본 고안은 이러한 문제점을 해결하기 위한 것으로, 본 고안의 목적은 파이프의 배열구조를 개선하여 동일한 크기의 외곽사이즈안에 더 많은 파이프와 핀을 배열시킬 수 있어 열교환성능을 증가시키는 열교환기를 제공하는데 있다.The present invention is to solve this problem, it is an object of the present invention to improve the arrangement of the pipe to arrange more pipes and fins in the outer size of the same size to provide a heat exchanger to increase the heat exchange performance.
상기 목적을 달성하기 위한 본 고안은, 소정간격으로 적층 배열된 다수의 전열핀, 상기 전열핀을 관통하여 그 단부에서 종방향으로 1차 U형 밴딩된 다수의 제1밴딩부를 가진 열과 상기 열의 어느 일단에서 횡방으로 2차 U형 밴딩된 제2밴딩부를 가진 행이 일체로 다수개 배열되어 구성된 냉매파이프를 갖춘 열교환기에 있어서, 상기 제2차밴딩에 의한 냉매파이프의 열과 열 사이의 간격보다 상기 제2차밴딩부와 대향하는 쪽의 파이프의 열과 열 사이의 간격이 좁게 형성된 것을 특징으로 한다.The present invention for achieving the above object, a plurality of heat transfer fins arranged in a predetermined interval, a row having a plurality of first bending portion that is first U-shaped bend in the longitudinal direction through the heat transfer pins at any end and A heat exchanger having a refrigerant pipe having a plurality of rows having a second bending portion, which is secondly U-shaped bent at one end in a row, integrally arranged in a plurality of rows, wherein Characterized in that the gap between the column and the row of pipes on the side opposite to the secondary bending portion formed narrow.
이하에서는 첨부도면을 참조하면서 본 고안의 실시예를 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제3도는 본 고안에 따른 열교환기의 분해 사시도이다. 이에 도시된 바와 같이, 열교환기(10)는 소정간격으로 적층 배열된 다수의 전열핀(20)과 이 전열핀(20)을 관통하는 냉매파이프(30)로 구성된다. 냉매파이프(30)는 전열핀(20)을 관통하여 그 단부에서 종방향으로 1차 U형 밴딩된 다수의 제1밴딩부(31)를 가진 열과 상기 열의 어느 일단에서 횡방으로 2차 U형 밴딩된 제2밴딩부(32)를 가진 행이 일체로 다수개 배열되어 구성되는데, 본 고안의 특징에 따라 제2차밴딩부와 대향하는 쪽의 냉매파이프의 열과 열 사이의 간격이 상기 제2차밴딩에 의한 파이프의 열과 열 사이의 간격보다 좁게 형성된다.3 is an exploded perspective view of a heat exchanger according to the present invention. As shown in the figure, the heat exchanger 10 is composed of a plurality of heat transfer fins 20 arranged at a predetermined interval and a refrigerant pipe 30 passing through the heat transfer fins 20. The refrigerant pipe 30 penetrates the heating fins 20 and has a plurality of first bending portions 31 which are firstly U-shaped bent in the longitudinal direction at the end thereof, and the second U-banding laterally at either end of the rows. A plurality of rows having the second bending portion 32 are arranged integrally, and according to a feature of the present invention, the interval between the columns and the columns of the refrigerant pipes facing the second bending portion is different from the second difference. It is formed narrower than the spacing between the rows of pipes by banding.
이때 냉매파이프(30)는 홀수의 행으로 구성되어 이웃하는 각 열의 간격이 제2차밴딩이 이루어진 일단보다 밴딩이 이루어지지 않은 타단이 상대적으로 좁게 형성되게 함으로써 도면과 같은 구조를 이루게 된다. 제4도는 이러한 구조를 명확하게 보이기 위한 평면도이다. 이에 도시된 바와 같이, 냉매파이프(30)의 각열은 제2밴딩부(32)에 의해 연결되는데, 제2밴딩부(32)의 반대측에서 각열의 간격이 제2밴딩부(32)에서의 그것보다 좁음을 알 수 있고, 이러한 제2밴딩부와 그 반대측이 교호적으로 배열되므로 제품의 전체 사이즈를 감소시킬 수 있음을 알 수 있다. 이러한 본 고안의 따른 열교환기에 의하면 종래의 각 열이 평행한 파이프 배열에 비해 전체 사이즈가 약 2/3정도로 감소된다.In this case, the refrigerant pipe 30 is formed in an odd number of rows so that the other end of the neighboring columns is formed to be relatively narrower than the other end where the second banding is made, thereby forming a structure as shown in the drawing. 4 is a plan view for clearly showing such a structure. As shown here, each row of refrigerant pipes 30 is connected by a second bending portion 32, with the spacing of the rows on the opposite side of the second bending portion 32 from the second bending portion 32. It can be seen that the narrower, and the second bending portion and the opposite side are alternately arranged to reduce the overall size of the product. According to the heat exchanger according to the present invention, the overall size is reduced to about 2/3 compared to the pipe arrangement in which each column is parallel.
또한, 이러한 본 고안의 열교환기는 그 양측에서 지지판(40)에 의해 지지 고정된다. 이 지지판(40)에는 제1밴딩부(31)와 제2밴딩부(32)가 삽입되는 삽입홈(41)이 형성되어 이들 제1,2밴딩부(31)(32)가 지지판(40)의 외측으로 돌출되어 설치된다.In addition, the heat exchanger of the present invention is supported and fixed by the support plate 40 on both sides. The support plate 40 is formed with an insertion groove 41 into which the first bending portion 31 and the second bending portion 32 are inserted, so that the first and second bending portions 31 and 32 are supported by the support plate 40. Protrude outward of the installation.
한편, 이러한 열교환기는 냉장고 및 이와 유사한 냉동장치나 공기조화기에 장착되는데, 특히 냉장고에 장착되어 응축기로 사용될 경우에는 기계실 내부에 장착된다. 이때는 압축기, 압축기 냉각용 팬, 본 고안의 열교환기(응축기) 순으로 배치하여 압축기 냉각용 팬의 강제 송풍력을 이용하는 것이 바람직하고, 압축기에서 나온 냉매가스가 압축기에서 가까운 쪽의 파이프를 먼저 통과하고 차례로 먼쪽의 파이프를 통과하도록 배치하는 것이 더욱 바람직하다.On the other hand, such a heat exchanger is mounted in a refrigerator and similar refrigerating device or air conditioner, in particular, in the case where the refrigerator is used as a condenser, it is mounted inside the machine room. In this case, it is preferable to arrange the compressor, the compressor cooling fan, and the heat exchanger (condenser) of the present invention in order to use the forced blowing force of the compressor cooling fan, and the refrigerant gas from the compressor passes through the pipe close to the compressor first. More preferably, they are arranged to pass through the pipe in the far side in turn.
이상에서 상세히 설명한 바와 같이, 본 고안의 따른 열교환기에 의하면, 파이프의 배열을 개선함으로써 제품 전체 사이즈를 줄일 수 있을 뿐만 아니라 전열핀을 수를 늘일 수 있어 궁극적으로는 열전달량을 증가시킬 수 있다.As described in detail above, according to the heat exchanger according to the present invention, by improving the arrangement of the pipe can not only reduce the overall size of the product, but also increase the number of heat transfer fins can ultimately increase the amount of heat transfer.
