Abstract

본 발명은 열 교환기용 다중관(1)에 관한 것으로, 특히 외측관(2)의 관통구멍(2a)안에 내측관(3)이 상기 외측관(2)과 동축으로 삽입 설치되고, 이 내측관(3)의 외주면과 외측관(2)의 내주면 사이 공간에는 다수개의 지지관(4)이 그 원주둘레를 따라 서로 밀착하면서 삽입 설치된 구조로되어 열교환기 전체크기를 컴팩트하게 줄일 수 있고, 일반 범용 파이프를 사용하여 제작할 수 있으므로 제작코스트도 낮으며, 전열면적이 증대되어 전열효율이 우수한 열교환기용 다중관에 관한 것이다. (대표도면 : 제1도)The present invention relates to a multi-pipe (1) for heat exchanger, in particular, the inner tube (3) is inserted coaxially with the outer tube (2) in the through hole (2a) of the outer tube (2), the inner tube In the space between the outer circumferential surface of (3) and the inner circumferential surface of the outer tube (2), a plurality of support tubes (4) are inserted and installed in close contact with each other along the circumference of the circumference to reduce the overall size of the heat exchanger compactly, Since it can be manufactured using a pipe, the manufacturing cost is low, and the heat transfer area is increased, and the heat transfer efficiency is excellent.
