Abstract

본 발명은 튜브를 통해 유동하는 유체와 튜브의 외부 주위로 유동하는 유체 사이에 열이 전달되며 열 교환 프로세스중 튜브 외부의 유체가 비등하는 열 교환기에서 사용하기 위한 열 전달 튜브(10)에 관한 것이다. 튜브는 외부 면(13)주위로 나선형으로 연장된 적어도 하나의 핀 희선(20)을 갖는다. 노치(30)의 패턴은 튜브의 원주에 대해 소정 간격으로 핀 회선에 대해 경사가(α)으로 연장된다. 각 쌍의 인접 노치 사이에는 스파이크(22)가 있다. 말단 팁(3)은 편평화된다. 스파이크의 최대 폭(WT)은 축 회선의 인접부의 폭(WR)보다 크며 인접 핀 회선 내의 스파이트크의 말단 팁과 중첩되어 인접 핀 회선 사이에 그리고 중첩된 팁 아래에 리엔터런트 공동을 형성하기에 충분한 폭이다. 핀 회선, 노치 및 스파이크는 맨드릴과, 첫째 피닝 디스크(63)의 갱, 둘째, 노칭 휠(66), 셋째, 매끄러운 휠(67) 사이에서 튜브 벽을 롤링함으로써 튜브에 형성된다. 튜브의 제조중, 회전하며 진행하는 튜브 , 노칭 휠 및 매끄러운 휠의 상호작용에 의해, 스파이크의 팁의 경사각의 각도(β)는 노치각에 대해 경사진다.
