본 발명은 열교환기에 관한 것으로, 특히 응축수배출을 용이하도록 한 열교환기에 관한 것이다.The present invention relates to a heat exchanger, and more particularly to a heat exchanger to facilitate the discharge of condensate.
종래의 열교환기는 제1도에 도시된 바와 같이, 일정한 거리를 두고 위치해 있는 한쌍의 헤더(1)(1')와, 상기 헤더사이 뻗어 있어 냉매의 통로역할을 하는 다수개의 플랫튜브(3)와, 튜브와 튜브사이에 위치하여 열을 방열하는 핀(5)으로 구성되어 있고, 이 모든 부품들이 일체로 브레이징되어 있다.Conventional heat exchangers, as shown in Figure 1, a pair of headers (1) (1 ') positioned at a constant distance, and a plurality of flat tubes (3) extending between the headers to act as a passage for the refrigerant and And a fin (5) located between the tube and the tube to dissipate heat, and all these parts are integrally brazed.
냉매는 입구관(미도시)을 통하여 헤더(1)로 들어오고 헤더에서 각 튜브(3)들로 분배되고, 분배된 냉매는 각 튜브를 흐르면서 핀(5)을 통하여 열을 방출하고 응축되어 다시 헤더로 모아지고 출구관(미도시)을 통하여 열교환기를 빠져나간다.Refrigerant enters the header (1) through an inlet tube (not shown) and is distributed to each tube (3) in the header, and the distributed refrigerant discharges heat through the fin (5) and condenses again as it flows through each tube. Collected by the header and exits the heat exchanger through an outlet tube (not shown).
제2도는 종래 이러한 열교환기의 튜브의 단면을 나타낸 것으로, 하나의 냉매유로의 수력직경을 0.15inch∼0.040inch로 하기 위하여 물결모양의 스페이서(4)를 플랫튜브(3)내에 접합시켰다.FIG. 2 shows a cross section of a tube of such a heat exchanger in the related art. In order to make the hydraulic diameter of one refrigerant passage 0.15 to 0.040 inch, a wavy spacer 4 is bonded into the flat tube 3.
이러한 종래의 열교환기는 고성능 핀과 수력직경이 적은 유로를 갖는 플랫튜브를 채용하여 성능이 우수하고 공기측 압력손실이 적은 잇점이 있지만 플랫튜브를 채용함으로 증발기로 사용시 응축수의 배출이 용이하지 않아 증발기로 사용시 성능이 저하되는 문제점이 있다.The conventional heat exchanger adopts a flat tube having a high-performance fin and a hydraulic channel having a small hydraulic diameter, and has excellent performance and low air pressure loss. However, by adopting a flat tube, condensate is not easily discharged when used as an evaporator. There is a problem that performance decreases when using.
본 발명은 이러한 종래기술의 문제점을 해결하기 위한 것으로, 증발기 적용시 응축수 배출을 용이하게 할 수 있는 열교환기의 제공을 목적으로 한다.The present invention is to solve the problems of the prior art, it is an object of the present invention to provide a heat exchanger that can facilitate the discharge of condensed water when the evaporator is applied.
상기 목적을 달성하기 위하여 본 발명의 열교환기는, 한쌍의 헤더가 일정한 간격을 두고 위치해 있고, 상기 헤더와 헤더사이에 복수의 세경관로 이루어진 세경관군이 상하로 병렬로 뻗어있어 냉매의 통로역할을 하고, 열을 방열하는 핀과 상하의 세경관군 사이에 위치하고 있는 것을 특징으로 한다.In order to achieve the above object, the heat exchanger of the present invention has a pair of headers positioned at regular intervals, and a pair of tubular tubular tubes having a plurality of tubular tubular tubes extending vertically in parallel between the header and the header serves as a passage for the refrigerant. It is characterized in that it is located between the fins for radiating heat and the upper and lower capillary tube group.
이하, 첨부도면에 의거하여 본 발명의 열교환기를 상세히 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, the heat exchanger of this invention is demonstrated in detail based on an accompanying drawing.
본 발명의 열교환기는 제3도 내지 제5도에 도시된 바와같이, 증발기로 사용시 응축수의 배출을 용이하게 하기 위하여 한쌍의 헤더(10)(10')가 일정한 간격을 두고 위치해 있고, 상기 헤더와 헤더사이에 소정의 간격을 갖는 복수의 세경관(13')로 이루어진 세경관군(13)이 상하로 병렬로 뻗어있어 냉매의 통로역할을 하고, 열을 방열하는 핀(15)가 상하의 세경관군사이에 위치하고 있다.As shown in FIGS. 3 to 5, the heat exchanger of the present invention has a pair of headers 10 and 10 'positioned at regular intervals to facilitate the discharge of condensate when used as an evaporator. A thin capillary tube group 13 composed of a plurality of capillary tubes 13 'having a predetermined distance between the headers extends up and down in parallel to serve as a passage for the refrigerant, and a fin 15 for dissipating heat is provided between the upper and lower capillary tube groups. Located in
상기 세경관(13)의 외경(D)은 2 4로 하고, 응축수의 배출을 용이하게 하도록 세경관군(13)의 세경관(13')간의 간격(d)은 0.1 2로 한다.The outer diameter D of the tubular tube 13 is 2 4 In order to facilitate the discharge of condensed water, the interval d between the small diameter pipes 13 'of the small diameter pipe groups 13 is 0.1. 2 Shall be.
헤더(10)에 있는 입구관(8)을 통하여 들어온 냉매는 각 세경관군(13)로 분배되고 분배된 냉매는 세경관군(13)들의 사이에 있는 핀(15)을 통하여 열을 전달하고 헤더(10)에 있는 출구관(9)을 통하여 열교환기를 빠져나간다.The refrigerant entering through the inlet pipe 8 in the header 10 is distributed to each of the tubular tube groups 13, and the distributed refrigerant transfers heat through the pins 15 between the tubular tube groups 13. The heat exchanger exits through the outlet tube (9).
이러한 본 발명의 열교환기는 일정간격을 둔 세경관들로 이루어진 세경관군을 상하 병렬로 연결하여 냉매유로로 사용하므로 종래 열교환기의 공기측 저압력손실, 열전달 효율상승등 장점을 그대로 가지고 있으면서 응축수의 배출이 용이하여 증발기로도 사용할 수 있는 잇점이 있다.Since the heat exchanger of the present invention connects three groups of thin tubes having a predetermined interval in up and down parallel and uses them as refrigerant flow paths, the condensed water is discharged while still having the advantages such as low pressure loss in the air side of the conventional heat exchanger and an increase in heat transfer efficiency. This has the advantage of being easy to use as an evaporator.
