Abstract

열 교환 튜브가 튜브의 열 교환 성능을 보강하도록 내부 리브를 갖는다. 이 리브들은 횡 단면이 삼각형 또는 직사각형이나 리브의 임계 변수에 대한 특정 범위의 값을 갖는다. 양호한 실시예에서, 리브는 튜브의 내주 주위에 고르게 분포되고 튜브는 구리 또는 구리합금으로 제조된다.The heat exchange tube has an inner rib to reinforce the heat exchange performance of the tube. These ribs are triangular or rectangular in cross section, but have a specific range of values for the critical parameters of the rib. In a preferred embodiment, the ribs are evenly distributed around the inner circumference of the tube and the tube is made of copper or copper alloy.
