Weld to the separator plate 4, but form a plurality of copper tubes (3) by twisting at least approximately 90 °, the air inlet (5) and the air outlet (6) to the inside of the separator (4) to the outside Forming a dry air inlet (7) and an outlet (8) A plurality of copper tubes 13 are inserted into the first heat exchange tube 1 and the case 12 in which the shape blocking plates 9 are coupled at equal intervals, and both ends of the copper tubes are welded with the separating plate 14, but the plurality of copper tubes (13) is formed by twisting approximately 90 ° or more, and the refrigerant inlet 17 and the refrigerant outlet 18 inside the separator 14 and the air inlet 15 and the air outlet 16 on the outside. Formed in the case 12, the air supplied to the air inlet 15 by the bisecting plate 27 is rotated at the arc-shaped end 10 on the other side to be discharged to the air outlet 16, and It consists of the 2nd heat exchange pipe 11 which combined the shape blocking board 19 at equal intervals.
상기 제1열교환관(1)의 공기주입구(5)는 공기를 공급하는 별도의 콤프레샤에 연결되며, 공기 배출구(6)는 제2열교환관(11)의 건조공기 입구(15)에 연결되고, 제2열교환관(11)의 건조공기 배출구(16)는 제1열교환관(1)의 공기입구(7)와 연결되며 제1열교환관(11)의 공기 배출구(8)는 각종 기계 기구에 연결되어 건조공기를 공급하게 되는 것이다.The air inlet 5 of the first heat exchange tube 1 is connected to a separate compressor for supplying air, and the air outlet 6 is connected to the dry air inlet 15 of the second heat exchange tube 11. The dry air outlet 16 of the second heat exchange tube 11 is connected to the air inlet 7 of the first heat exchange tube 1, and the air outlet 8 of the first heat exchange tube 11 is connected to various machine tools. To supply dry air.
또한 제2열교환관(11)의 냉매입구(17)는 냉매 출구(18)와 연결된 액분리기(20), 필터(21), 압축기(22), 수액기(23) 및 응축기(24)를 통하면서 냉매가 액체로 변하여 단일 팽창하는 팽창밸브(25)와 연결되어 냉매 입구(17)로 들어가는 냉매의 증발에 의해 동관(13)내로 통과하는 공기로 부터 열을 흡수하도록 구성된 것이다.In addition, the refrigerant inlet 17 of the second heat exchange tube 11 passes through a liquid separator 20, a filter 21, a compressor 22, a receiver 23, and a condenser 24 connected to the refrigerant outlet 18. While the refrigerant is converted into a liquid and connected to a single expansion expansion valve 25 is configured to absorb heat from the air passing through the copper tube 13 by the evaporation of the refrigerant entering the refrigerant inlet (17).
상기와 같은 구조로 된 본 고안은 제2도 및 제3도에서 나타난 것과 같이 내부에 결합되어 있는 다수의 동관(3)(13)이 비틀어져 있으므로 공기가 제1, 제2열교환관(1)(11)의 공기 입구(5)(15)로 공급된 공기는 동관(3)의 외부면에 많은 접촉을 하면서 차단판(9)의 사이로 이동하게되고, 동관(13)의 내부로 이동되는 공기는 회전력을 발생하면서 동관(13) 내부면을 스치며 이동하게되며, 이때 상호 공기 및 냉매가 열교환하면서 열교환 효과를 얻게되고 공기는 공기배출구(16)(8)로 배출하게 된다.In the present invention having the structure as described above, as shown in FIGS. 2 and 3, the plurality of copper tubes 3 and 13 coupled to the inside are twisted, so that air is first and second heat exchange tubes 1 and ( The air supplied to the air inlets 5 and 15 of the 11 is moved between the blocking plates 9 while making a lot of contact with the outer surface of the copper tube 3, and the air moved into the copper tube 13. The rotating force is generated while passing through the inner surface of the copper tube 13, and at this time, the air and the refrigerant exchange heat to obtain a heat exchange effect, and the air is discharged to the air outlets 16 and 8.
또한 제2열교환관(11)의 건조 공기입구(15)로 공급된 공기는 격판(27)에 의하여 2등분된 일측동관(13)으로 이동되어 타측의 호형끝단(10)에서 와류현상이 없이 유연하게 회전하면서 타측 동관(13)으로 이동하여 건조공기 배출구(16)로 배출하게 되므로 고온고압의 건조 공기의 이동에 충격등이 발생되지 않는 것이다.In addition, the air supplied to the dry air inlet 15 of the second heat exchange tube 11 is moved to the one-side copper tube 13 divided into two by the diaphragm 27 to be flexible without vortex at the arc-shaped end 10 of the other side. Rotating so as to move to the other side of the copper tube 13 is discharged to the dry air outlet 16 so that the impact light does not occur in the movement of the high temperature and high pressure dry air.
이와같이 구성되어 작동되는 열 교환기는 공기 및 냉매의 이동시 마찰력을 증대시키므로서 열교환효과를 높이고 열교환에 의하여 건조한 공기를 얻으므로써 건조공기를 사용하는 각종 산업용 기계기구의 부식 및 동파를 방지하게 할 뿐만 아니라, 공기의 흐름을 원활하게 하여 기계적 충격에 의한 소음 및 떨림의 방지로 수명을 연장시킬수 있도록 고안된 것이다.The heat exchanger configured and operated in this way not only prevents corrosion and freezing of various industrial machinery using dry air by increasing the heat exchange effect by increasing frictional force during movement of air and refrigerant, and by obtaining dry air by heat exchange. It is designed to extend the life by smoothing the flow of air to prevent noise and vibration caused by mechanical shock.
