Abstract

열 교환/열교환 본 발명은 열교환기용 튜브에 관한 것으로서, 열교환 효율을 높이기 위하여 열교환기에서 열교환 매체가 흐르는 통로로서, 다수 나란하게 설치되며 그들 사이에 넓은 전열 면적을 갖는 휜이 설치되어 있는 튜브에 있어서, 그 내부면에 유체가 흐르는 방향으로 소정의 길이와 폭을 갖는 복수의 돌출부가 서로 교번으로 엇갈리게 마련되어 있고, 그 외주면에 상기 휜의 접촉부 전체가 밀착되도록 된 것을 특징으로 하낟.Heat Exchange / Heat Exchange The present invention relates to a tube for a heat exchanger, and in order to improve heat exchange efficiency, a channel through which a heat exchange medium flows in a heat exchanger, and a tube having a fin having a large heat transfer area therebetween is provided in parallel with each other. And a plurality of protrusions having a predetermined length and width are alternately alternately disposed on the inner surface thereof, and the entire contact portion of the fin is in close contact with the outer circumferential surface thereof.

또한, 소정의 길이를 갖는 판부재의 일측면에 유체 흐름 방향으로 소정의 길이와 폭을 갖는 돌출부를 서로 교번으로 엇갈리게 형성하는 단계; 상기 돌출부가 형성된 판 부재를 폭 방향으로 말아서 그 양가장자리부를 접촉하여 그 돌출부가 안쪽으로 형성되게 하는 단계;를 포함하는 것을 특징으로 한다.In addition, the step of alternately forming the protrusions having a predetermined length and width alternately in the fluid flow direction on one side of the plate member having a predetermined length; And rolling the plate member on which the protrusion is formed in the width direction so as to contact both edge portions thereof so that the protrusion is formed inward.
