본 발명은 열교환기에 관한 것으로, 특히 응축수배출을 용이하도록 한 열교환기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchanger, and more particularly, to a heat exchanger that facilitates discharge of condensed water.
종래의 열교환기는 제 1 도에 도시된 바와 같이, 일정한 거리를 두고 위치해 있는 한 쌍의 헤더(1)(1')와, 상기 헤더사이 뻗어있어 냉매의 통로역할을 하는 다수개의 플랫튜브(3)와, 튜브와 튜브사이에 위치하여 열을 방열하는 핀(5)으로 구성되어 있고, 이 모든 부품들이 일체로 브레이징되어 있다.As shown in FIG. 1, the conventional heat exchanger includes a pair of headers 1 and 1 'positioned at a predetermined distance, a plurality of flat tubes 3 extending between the header and serving as a passage for refrigerant, And a fin (5) positioned between the tube and the tube to dissipate heat, all of which are brazed together.
냉매는 입구관(미도시)을 통하여 헤더(1)로 들어오고 헤더에서 각 튜브(3)들로 분배되고, 분배된 냉매는 각튜브를 흐르면서 핀(5)을 통하여 열을 방출하고 응축되어 다시 헤더로 모아지고 출구관(미도시)을 통하여 열교환기를 빠져나간다.The refrigerant enters the header 1 through an inlet tube (not shown) and is distributed from the header to each tube 3, and the divided refrigerant discharges heat through the tube 5, flows through each tube, Collected in the header and exits the heat exchanger through an outlet pipe (not shown).
제2도는 종래 이러한 열교환기의 튜브의 단면을 나타낸 것으로, 하나의 냉매유로의 수력직경을 0.15inch~0.040inch로 하기 위하여 물결모양의 스페이서(4)를 플랫 튜브(3)내에 접합시켰다.FIG. 2 is a cross-sectional view of a tube of such a heat exchanger according to the related art. In order to make the hydraulic diameter of one refrigerant passage 0.15 inch to 0.040 inch, a wavy spacer 4 is bonded in 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.Such a conventional heat exchanger employs a flat tube having a high performance pin and a small hydraulic diameter flow path, and has an excellent performance and a low pressure loss on the air side. However, since a flat tube is employed, the discharge of condensed water is not easy. There is a problem that the performance is lowered when used.
본 발명은 이러한 종래기술의 문제점을 해결하기 위한 것으로, 증발기 적용시 응축수 배출을 용이하게 할 수 있는 열교환기의 제공을 목적으로 한다.SUMMARY OF THE INVENTION It is an object of the present invention to provide a heat exchanger capable of facilitating discharge of condensed water when applying an evaporator.
상기 목적을 달성하기 위하여 본 발명의 열교환기는, 한 쌍의 헤더가 일정한 간격을 두고 위치해 있고, 상기 헤더와 헤더사이에 복수의 세경관로 이루어진 세경관군이 상하로 병렬로 뻗어있어 냉매의 통로역할을 하고, 열을 방열하는 핀과 상하의 세경관군사이에 위치하고 있는 것을 특징으로 한다.In order to attain the above object, the heat exchanger of the present invention is characterized in that a pair of headers are spaced apart from each other at regular intervals, and a plurality of narrow tubes composed of a plurality of three tubes are vertically and parallelly arranged between the header and the header, And is located between the pins for dissipating heat and the upper and lower narrow tube groups.
이하, 첨부도면에 의거하여 본 발명의 열교환기를 상세히 설명한다.Hereinafter, the heat exchanger of the present invention will be described in detail with reference to the accompanying drawings.
본 발명의 열교환기는 제 3 도 내지 제 5 도에 도시된 바와 같이, 증발기로 사용시 응축수의 배출을 용이하게 하기 위하여 한 쌍의 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 통로역할를 하고, 열을 방열하는 핀(15)가 상하의 세경관군사이에 위치하고 있다.As shown in FIGS. 3 to 5, in the heat exchanger of the present invention, a pair of headers 10 and 10 'are spaced apart from each other at a predetermined interval in order to facilitate discharge of condensed water when used as an evaporator, Diameter tube group 13 composed of a plurality of three-tube tubes 13 'having a predetermined gap between the header and the header are vertically arranged in parallel so as to serve as a passage for the coolant, and a fin 15 for radiating heat is disposed between the upper and lower tubes .
상기 세경관(13)의 외경(D)은 2mm~4mm로 하고, 응축수의 배출을 용이하게 하도록 세경관군(13)의 세경관(13')간의 간격을 0.1mm~2mm로 한다.The outer diameter D of the three-sided pipe 13 is 2 mm to 4 mm and the interval between the three pipes 13 'of the large diameter pipe group 13 is set to 0.1 mm to 2 mm so as to facilitate discharge of the condensed water.
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 introduced through the inlet pipe 8 in the header 10 is distributed to each of the narrow tube groups 13 and the divided refrigerant transfers heat through the pin 15 between the narrow tube groups 13, 10) through the outlet pipe (9) in the heat exchanger.
이러한 본 발명의 열교환기는 일정간격을 둔 세경관들로 이루어진 세경관군을 상하병렬로 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 uses a narrow-gauge tube composed of three-dimensionally spaced tubes as a refrigerant passage by connecting the upper and lower parallel tubes in parallel, it has advantages such as low pressure loss on the air side and increase in heat transfer efficiency of the conventional heat exchanger, So that it can be used as an evaporator.
