열교환용 핀튜브의 제작방법Manufacturing method of fin tube for heat exchange

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명의 제작방법에 따라 박육관에 전열핀이 고정부착된 상태의 부분상태의 부분 단면도,1 is a partial cross-sectional view of a partial state of the heating pin fixed to the thin tube according to the manufacturing method of the present invention,

제2도는 본 발명 전열핀부재를 이루는 브레이징 필러메탄이 피막된 금속스트립의 전개도,2 is an exploded view of a metal strip coated with a brazing filler metal forming the heat transfer fin member of the present invention;

제3도는 제2도의 금속스트립을 본 발명의 전열핀부재를 이루도록 절곡성형시켜 배열한 상태의 부분단면도이다.3 is a partial cross-sectional view of the metal strip of FIG.

Claims (1)

부레이징필레메탈이 피막된 금속스트립(3)을 길이방향을 따라 펼쳐지면서 한쪽 측면가장자리와 소정간격을 두고 단면이 〃 ㄱ〃자형상으로 되도록 절곡시켜 부착부(3a)와 전열핀부(3b)를 갖추게 한다음, 그 폭방향의 절곡된 쪽으로 구부리면서 상기 전열핀부(3b)가 반경의 바깥쪽을 향하도록 두께가 1mm정도인 박육관(1)의 바깥 원주면에 상기 부착부(3a)가 직접 접하도록 나선형을 감아 그 상태를 유지시키면서 브레이징웰딩법으로 부착부(3a)를 박육관(1)에 고정부착시키도록 된 열교환기용 핀튜브의 제작방법.The metal strip (3) coated with the buried fillet metal is bent along the longitudinal direction and bent in a cross-section so as to have a 와 a-shape at a predetermined distance from one side edge, thereby attaching the attachment portion (3a) and the heat transfer fin portion (3b). After attaching, the attachment portion 3a is directly in contact with the outer circumferential surface of the thin tube 1 having a thickness of about 1 mm so that the heat transfer fin portion 3b faces the outside of the radius while bending the bent side in the width direction thereof. A method of manufacturing a fin tube for a heat exchanger, wherein the attaching portion (3a) is fixedly attached to the thin tube (1) by the brazing welding method while winding the spiral to maintain the state. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
