Description

열교환기구조Heat exchanger structure

본 발명은 열교환기에 관한 것으로서, 특히 플랫튜브형 열교환기의 플랫튜브와 핀의 구조를 변경하여 증발기에 적용할 수 있도록 한 열교환기구조에 관한 것이다.The present invention relates to a heat exchanger, and more particularly to a heat exchanger structure that can be applied to the evaporator by changing the structure of the flat tube and fin of the flat tube type heat exchanger.

종래 플랫튜브형 열교환기는 제1도에 도시된 바와 같이, 일정한 간격을 두고 위치한 한쌍의 헤더(1, 1')와, 상기 헤더(1)에 형성되어 냉매가스가 유입되는 입구관(2)과, 다른쪽 헤드(1')에 형성되어 냉매가스가 토출되는 출구관(3)과, 상기 헤더(1, 1')의 사이에 위치하며 냉매의 유로 역할을 하는 다수개의 플랫튜브(4)와, 상기 플랫튜브(4)의 사이에 위치하며 열을 방열하는 핀(5)으로 구성되며, 상기 헤더(1, 1'), 플랫튜브(2) 및 핀(3)이 일체형으로 용접되어 있다.Conventional flat tube heat exchanger, as shown in Figure 1, a pair of headers (1, 1 ') at regular intervals, the inlet tube (2) formed in the header (1), the refrigerant gas flows, An outlet pipe (3) formed at the other head (1 ') to discharge the refrigerant gas, and a plurality of flat tubes (4) positioned between the headers (1, 1') and serving as a flow path for the refrigerant; It is composed of a fin (5) located between the flat tube (4) to dissipate heat, the header (1, 1 '), the flat tube (2) and the pin (3) is integrally welded.

그리고, 상기 플랫튜브(4) 내부에는 제2도와 같이 냉매유로의 수력직경을 0.15~0.040inch로 하기 위하여 물결모양의 스페이서(6)가 접합되었다.And, inside the flat tube 4, a wavy spacer 6 was joined to make the hydraulic diameter of the refrigerant flow path 0.15 to 0.040 inch, as shown in FIG.

이와같이 구성된 종래의 플랫튜브형 열교환기는 냉매가스가 입구관(2)을 통하여 헤더(1)로 유입되고, 상기 헤더(1)에서 각 플랫튜브(4)로 분배되며, 상기 플랫튜브(4)로 분배된 냉매가스는 각 플랫튜브(4)내를 흐르면서 핀(5)을 통하여 흡입공기와 열교환을 실시하고 응축되어 다시 헤더(1')로 모아진 후 출구관(3)을 통하여 열교환기 외부로 토출된다.In the conventional flat tube heat exchanger configured as described above, the refrigerant gas flows into the header 1 through the inlet pipe 2, and is distributed to each flat tube 4 from the header 1, and distributed to the flat tube 4. The refrigerant gas flows through each of the flat tubes 4, heat exchanges with the intake air through the fins 5, is condensed, collected into the header 1 ', and then discharged to the outside of the heat exchanger through the outlet pipe 3. .

이때, 공기측 압력손실을 줄이도록 플랫튜브(4)에 접합된 물결모양의 스페이서(6)에 의해 냉매유로의 수력직경이 0.15~0.040inch로 유지되는 것이다.At this time, the hydraulic diameter of the refrigerant flow path is maintained at 0.15 to 0.040 inch by the wavy spacer 6 bonded to the flat tube 4 to reduce the air side pressure loss.

그러나 이러한 종래의 플랫튜브형 열교환기는 고성능 핀과, 수력직경이 작은 유로를 갖는 플랫튜브를 채용하므로 성능이 우수하고, 공기측 압력손실이 적은 잇점이 있지만 증발기로 사용시에는 응축수 배출이 용이하지 않아 성능이 저하되는 문제점이 있었다.However, the conventional flat tube type heat exchanger adopts a high performance fin and a flat tube having a small hydraulic diameter, so that the performance is excellent and the air pressure loss is low. However, when used as an evaporator, condensate is not easily discharged. There was a problem of deterioration.

본 발명은 이러한 점을 감안하여 튜브와 핀을 일체형으로 동시에 압출한 관군을 한 쌍의 헤더 사이에 상하 병렬로 연결하여 증발기에 적용시 응축수 배출을 원활히 하는 데 그 목적이 있다.In view of this point, an object of the present invention is to smoothly discharge condensate when applied to an evaporator by connecting a tube group in which the tube and the fins are integrally extruded simultaneously and vertically between a pair of headers.

이하, 본 발명을 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제3도는 본 발명에 의한 열교환기의 구성도를 나타낸 것으로서, 냉매가스의 유로인 튜브(101), 열을 방열하는 핀(102)이 동시에 압출되어 일체로 형성된다.3 is a block diagram of a heat exchanger according to the present invention, in which a tube 101, which is a flow path of refrigerant gas, and a fin 102 for dissipating heat are simultaneously extruded and integrally formed.

상기 튜브(101)의 단면은 응축수 배출이 용이하도록 원형으로 구성되고, 상기 튜브(101)의 외경은 2~4mm정도로 구성되며, 상기 튜브(101)의 갯수는 2~5개로 구성된다.The cross section of the tube 101 is configured in a circular shape to facilitate the discharge of condensate, the outer diameter of the tube 101 is composed of about 2 ~ 4mm, the number of the tube 101 is composed of 2 to 5.

그리고, 상기 튜브(101)의 양단 및 튜브(101)의 사이에 형성되는 핀(102)에는 제3도 및 제4도와 같이, 물빠짐이 용이하도록 루버(102a) 또는 슬릿(102b)이 성형되고, 상기 일체형으로 형성된 튜브(101)와 핀(102)은 헤더(도면상에 도시되지 않음)에 상하 병렬로 연결된다.In addition, the louver 102a or the slit 102b is formed in the fin 102 formed between both ends of the tube 101 and the tube 101 so as to easily drain the water as shown in FIGS. 3 and 4. The tube 101 and the fin 102 formed integrally are connected to the header (not shown) in parallel up and down.

이와같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.

먼저, 냉매가스가 입구관을 통하여 헤더로 유입되고, 상기 헤더로 유입된 냉매가스는 각 튜브(101)로 분배되며, 상기 튜브(101)로 분배된 냉매가스는 튜브(101)내를 흐르면서 튜브(101)와 일체로 형성된 핀(102)을 통하여 열을 방출하고 응축되어 다시 헤더로 모아진 후 출구관을 통하여 열교환기 외부로 토출된다.First, the refrigerant gas is introduced into the header through the inlet pipe, the refrigerant gas introduced into the header is distributed to each tube 101, the refrigerant gas distributed to the tube 101 flows through the tube 101 tube Heat is discharged through the fin 102 formed integrally with the 101, condensed, collected into the header, and then discharged to the outside of the heat exchanger through the outlet pipe.

이때, 상기 튜브(101)의 단면이 원형으로 구성되므로 증발기에 적용시 응축수의 배출이 원활해지게 되고, 상기 튜브(101)와 핀(102)이 동시에 압출되어 일체로 형성되므로 공정 중 튜브(101)와 핀(102)의 용접부분을 생략하게 되어 생산원가가 절감되고, 제작이 용이해지는 것이다.At this time, since the cross section of the tube 101 is formed in a circular shape, the discharge of condensed water becomes smooth when applied to the evaporator, and the tube 101 and the fin 102 are simultaneously extruded and integrally formed so that the tube 101 is in process. ) And the welding part of the pin 102 is omitted, the production cost is reduced, and the production is easy.

그리고, 상기 튜브(101) 사이의 핀(102)에 성형된 루버(102a) 또는 슬릿(102b)에 의해 물빠짐이 용이해지고, 상기 튜브(101) 양단의 핀(102)에 성형된 루버(102a) 또는 슬릿(102b)에 의해 저속에서도 경계층 선단효과(슬릿 또는 루버와 같이 전열면을 분할하여 사용하면 열전달계수가 높은 선단이 반복되므로 높은 열전달계수를 유지할 수 있다)로 높은 전열성능을 얻을 수 있게 된다.Water is easily drained by the louver 102a or the slit 102b formed in the fins 102 between the tubes 101, and the louver 102a formed in the fins 102 at both ends of the tube 101. ) Or the slit 102b to obtain high heat transfer performance at the low speed by the boundary layer tip effect (when splitting the heat transfer surface like slit or louver, the tip with high heat transfer coefficient is repeated, thus maintaining high heat transfer coefficient). do.

이상에서 설명한 바와 같이 본 발명은 튜브와 핀을 동시에 압출하여 일체형으로 형성하므로 제작공정 중 튜브와 핀의 용접을 생략하게 되어 생산원가가 절감되고, 제작이 용이해 지며, 상기 튜브의 단면을 원형 형상으로 구성하므로 증발기에 적용시 응축수의 배출이 용이해 지며, 상기 튜브의 양단 및 튜브와 튜브 사이의 슬릿 또는 루버를 성형하여 사용하게 되므로 물빠짐이 용이해 지고, 저속에서도 경계층 선단효과로 높은 전열성능을 얻을 수 있는 효과가 있다.As described above, the present invention is formed by integrally extruding the tube and the fin at the same time to omit the welding of the tube and the fin during the manufacturing process to reduce the production cost, easy to manufacture, the cross section of the tube in a circular shape Since the condensate is easily discharged when applied to the evaporator, water is easily drained by forming a slit or louver between the both ends of the tube and the tube and the tube, and high heat transfer performance is achieved by the boundary layer tip effect even at a low speed. There is an effect that can be obtained.
