핀-관 일체형 열교환기의 냉각핀 형성구조{COOLING PIN STRUCTURE OF HEAT EXCHANGER}Cooling fin formation structure of fin-tube integrated heat exchanger {COOLING PIN STRUCTURE OF HEAT EXCHANGER}

본 발명은 핀-관 일체형 열교환기의 냉각핀 형성구조에 관한 것으로, 보다상세하게는 냉매관과 냉각핀이 일체로 형성되고, 그 냉각핀들이 통풍저항과 물빠짐성을 고려하여 최적의 각도로 절곡형성되도록 한 핀-관 일체형 열교환기의 냉각핀 형성구조에 관한 것이다.The present invention relates to a cooling fin formation structure of a fin-tube integrated heat exchanger, and more particularly, a refrigerant pipe and a cooling fin are integrally formed, and the cooling fins are formed at an optimal angle in consideration of ventilation resistance and water drainage. It relates to a cooling fin forming structure of the fin-tube integrated heat exchanger to be bent.

일반적으로 열교환기는 에어컨, 냉장고, 쇼케이스 등에 설치되는 냉동사이클장치의 응축기와 증발기를 통칭하는 것으로, 이와 같은 열교환기는 설치위치에 따라 전열매체인 냉매의 상변화에 의해 열을 방출하거나 흡수하므로 이를 이용하여 난방 및 냉방에 활용되어 진다.In general, the heat exchanger collectively refers to the condenser and evaporator of a refrigeration cycle device installed in an air conditioner, a refrigerator, a showcase, and the like. It is used for heating and cooling.

상기 열교환기중 가장 널리 알려진 열교환기는 냉매관에 다수개의 냉각핀들이 삽입되어 있는 형태의 핀-관형 열교환기로서, 이는 냉장고나 에어컨 등의 증발기로 주로 이용되며, 냉매가 냉매관의 내부로 순환하며 냉매관을 통하여 외부공기와의 열교환이 이루어지는 동시에 냉매관에 밀착되도록 삽입되어 있는 냉각핀들에 의해 열교환면적이 넓게 확대되어 열교환이 급속하게 이루어지게 된다.The most widely known heat exchanger of the heat exchanger is a fin-tubular heat exchanger in which a plurality of cooling fins are inserted into a refrigerant pipe, which is mainly used as an evaporator such as a refrigerator or an air conditioner, and the refrigerant circulates inside the refrigerant pipe. The heat exchange with the external air is carried out through the pipe and at the same time, the heat exchange area is widened by the cooling fins inserted in close contact with the refrigerant pipe so that the heat exchange is rapidly performed.

도 1은 상기와 같이 증발기로 이용되는 핀-관형 열교환기를 보인 사시도로서, 이에 도시된 바와 같이, 냉매가 순환될 수 있도록 냉매관(1)이 절곡 형성되어 있고, 그와 같이 절곡된 냉매관(1)에는 냉매관(1)에 접촉된 상태로 공기와의 열교환 면적을 확대시켜서 열교환효율을 증대시키기 위한 다수개의 냉각핀(2)들이 설치되어 있고, 상기와 같이 다단으로 절곡된 냉매관(1)의 양단부는 지지대(3)에 의하여 지지되어 있다.1 is a perspective view showing a fin-tubular heat exchanger used as an evaporator as described above, and as shown therein, the refrigerant pipe 1 is bent to circulate the refrigerant, and the refrigerant pipe bent as described above ( 1) is provided with a plurality of cooling fins (2) to increase the heat exchange efficiency by increasing the heat exchange area with air in contact with the refrigerant pipe (1), the refrigerant pipe (1) bent in multiple stages as described above Both ends of the support) are supported by the support 3.

그리고, 상기 냉매관(1)은 소정길이를 갖는 1개의 동 파이프를 "Ｓ"자 형태로 반복 절곡하여 다단을 이루도록 2열로 형성되어 있다.The refrigerant pipe 1 is formed in two rows so as to form a plurality of stages by repeatedly bending one copper pipe having a predetermined length in a "S" shape.

또한, 상기 냉각핀(2)들은 도 2에 도시된 바와 같이, 알루미늄 소재를 소정면적으로 가공한 평판체로서 중앙부에는 프레스가공에 의해 통공(2a)이 형성되어 있고, 그와 같이 통공(2a)이 형성된 냉각핀(2)들은 냉매관(1)에 삽입된 상태에서 냉매관(1)을 확관시키는 것에 의해 냉매관(1)의 외주면에 밀착되도록 고정되어 진다.In addition, as shown in Figure 2, the cooling fins (2), a flat plate formed by processing a predetermined aluminum material in the center portion is formed with a through hole (2a) by the press working, as such a through hole (2a) The formed cooling fins 2 are fixed to be in close contact with the outer circumferential surface of the refrigerant pipe 1 by expanding the refrigerant pipe 1 in a state of being inserted into the refrigerant pipe 1.

상기와 같은 구조의 핀-관형 열교환기(10)는 냉매가 냉매관(1)의 내부를 순환하며 외부 공기와의 열교환에 의해 열교환이 이루어지고, 그와 같이 열교환이 이루어질때에 냉매관(1)에 밀착되도록 고정되어 있는 냉각핀(2)들에 의하여 열교환면적이 확대되어 열교환 효율이 증대되어 진다.In the fin-tubular heat exchanger 10 having the above-described structure, the refrigerant circulates inside the refrigerant pipe 1 and heat exchange is performed by heat exchange with external air, and when the heat exchange is performed, the refrigerant pipe 1 Heat exchange area is increased by the cooling fins (2) that are fixed in close contact with the) increases heat exchange efficiency.

그러나, 상기와 같은 종래의 핀-관형 열교환기(10)는 열교환이 이루어질때에 주변공기의 절대습도량에 의해 냉매관(1)과 냉각핀(2)에 착상이 이루어지고, 그와 같이 착상된 것은 별도로 설치된 제상히터(미도시)에 의해 제상되어 지는데, 그와 같은 착상과 제상을 반복하게되면 동 파이프로 제작된 냉매관(1)과 알루미늄으로 제작된 냉각핀(2)의 열팽창계수의 차이에 의해 냉매관(1)과 냉각핀(2)의 통공(2a) 사이에 틈이 발생되고, 그와 같이 발생된 틈으로 제상수가 침입하여 틈새를 더욱 커지게 하여 열교환 효율을 감소시키고, 제상시 제상효율을 저하시키는 문제점이 있었다.However, the conventional fin-tubular heat exchanger 10 as described above is implanted into the refrigerant pipe 1 and the cooling fins 2 by the absolute humidity of the ambient air when heat exchange is performed, and thus is implanted. It is defrosted by a separate defrost heater (not shown), and if the above conception and defrost are repeated, the coefficient of thermal expansion of the refrigerant pipe (1) made of copper pipe and the cooling fin (2) made of aluminum is repeated. Due to the difference, a gap is generated between the refrigerant pipe 1 and the through hole 2a of the cooling fin 2, and defrost water penetrates into the gap thus generated to increase the gap, thereby reducing heat exchange efficiency. There was a problem in defrosting defrosting efficiency.

또한, 여러개의 냉각핀(2)들을 냉매관(1)에 일일이 삽입하고, 그와 같이 삽입된 냉각핀(2)을 냉매관(1)에 고정시키기 위한 확관작업을 실시하여야 하기 때문에 제작과정이 복잡한 문제점이 있었다.In addition, since the cooling fins 2 are inserted into the refrigerant pipe 1 one by one, and the expansion process for fixing the inserted cooling fins 2 to the refrigerant pipe 1 must be performed. There was a complicated problem.

또한, 냉매관(1)과 냉각핀(2)은 동과 알루미늄의 이종재질로서 시간이 경과되면 각 재질의 전위차에 의해 전위차부식이 급격히 진행되어 결과적으로 열교환기의 사용수명을 저하시키는 문제점이 있었다.In addition, the refrigerant pipe (1) and the cooling fin (2) is a heterogeneous material of copper and aluminum, and as time passes, the potential difference corrosion rapidly progresses due to the potential difference of each material, and as a result, the service life of the heat exchanger is reduced. .

상기와 같은 문제점들을 해결코자 최근에는 이 분야의 연구자들에 의하여 냉매관과 냉각핀이 일체로 형성되는 핀-관 일체형 열교환기에 관한 연구가 활발하게 진행되고 있다. 그러나, 상기와 같이 냉매관에 일체로 형성되는 냉각핀들의 각도는 통풍저항과 물빠짐성에 밀접한 관계가 있어서 열교환기의 성능에 크게 영향을 미치는 것에도 불구하고 그에 대한 적절한 설계가 이루어지지 못한 문제점이 있었다.In order to solve the above problems, recently, researchers in this field have been actively researching a fin-tube integrated heat exchanger in which a refrigerant pipe and a cooling fin are integrally formed. However, as described above, the angle of the cooling fins integrally formed in the refrigerant pipe is closely related to the ventilation resistance and the water drainage property, and thus the proper design for the heat exchanger is not achieved. there was.

상기와 같은 문제점을 감안하여 안출한 본 발명의 목적은 냉매관과 냉각핀을 일체로 형성하되, 그 냉각핀의 각도가 열교환성능을 향상시킬 수 있는 최적상태로 설계되도록 하는데 적합한 핀-관 일체형 열교환기의 냉각핀 형성구조를 제공함에 있다.An object of the present invention devised in view of the above problems is to form a refrigerant pipe and cooling fins integrally, but the fin-tube integral heat exchanger suitable for the angle of the cooling fins to be designed in an optimal state to improve heat exchange performance. It is to provide a cooling fin forming structure of the group.

이에 도시된 바와 같이, 본 발명의 냉각핀 형성구조를 가지는 핀-관 일체형 열교환기는 냉매가 통과될 수 있는 관체상의 냉매관(101)이 2열로 나란하게 형성되어 있고, 그와 같이 2열로 형성된 냉매관(101)의 사이에는 냉각핀(102)이 일체로 압출성형되어 있다.As shown in the drawing, the fin-tube integrated heat exchanger having the cooling fin formation structure according to the present invention has a coolant tube 101 through a tubular body in which two refrigerants can pass. The cooling fins 102 are integrally extruded between the pipes 101.

상기 냉매관(101)들은 일정폭과 높이를 가지도록 "Ｓ"자형상으로 반복적으로 절곡되어 있고, 그와 같은 냉매관(101)들의 양단부는 지지대(103)에 의하여 고정되어 있다.The coolant tubes 101 are repeatedly bent in a "S" shape to have a predetermined width and height, and both ends of the coolant tubes 101 are fixed by the support 103.

It is bent to.

상기 냉각핀(102)의 각도(θ)는 공기측 열전달측면과 착/제상측면을 고려하여야 하는데, 이러한 점들이 전열성능에 가장큰 영향을 미치기 때문이다. 따라서, 착상부분과 통풍저항 및 물빠짐성 등을 고려할 때 냉각핀(102)의 각도(θ)는 75도이상이 되어야 하고 90도를 넘지 않는 것이 바람직한 것으로 나타났다.The angle θ of the cooling fin 102 should consider the air side heat transfer side and the landing / defrost side, since these points have the greatest influence on the heat transfer performance. Therefore, in consideration of the implantation part, the ventilation resistance and the water drainage, etc., the angle θ of the cooling fin 102 should be 75 degrees or more and not more than 90 degrees.

상기와 같이 구성되어 있는 본 발명의 핀-관 일체형 열교환기는 냉매가 냉매관(101)의 내부를 순환하며 외부 공기와의 열교환에 의해 열교환이 이루어지고, 그와 같이 열교환이 이루어질때에 냉매관(101)에 일체로 형성된 냉각핀(102)들에 의하여 열교환면적이 확대되어 열교환 효율이 증대되어 진다.Fin-tube integrated heat exchanger of the present invention is configured as described above the refrigerant is circulated inside the refrigerant pipe 101 and the heat exchange is made by heat exchange with the outside air, when the heat exchange is made as such The heat exchange area is increased by the cooling fins 102 formed integrally with 101, thereby increasing heat exchange efficiency.

도 6은 본 발명의 증발기와 종래 증발기의 총합열전달계수의 비교시험 그래프로서, 이에 도시된 바와 같이, 종래에 증발기에 비하여 냉각핀(102)의 각도를 75도-90도로 형성한 본 발명의 증발기의 총합열전달계수(U)가 월등이 큰 것으로 나타났다.Figure 6 is a comparative test graph of the total heat transfer coefficient of the evaporator and the conventional evaporator of the present invention, as shown in the evaporator of the present invention formed the angle of the cooling fin 102 to 75 degrees to 90 degrees as compared to the conventional evaporator The total heat transfer coefficient of U was significantly higher.
