一、概述天津市建筑设计院和天津市建设局机电安装公司共同创制高温水肋片管道采暖。作为输送和散热合一的肋片管的具体做法是:以φ38×3的无缝钢管作导管,在管外穿以厚1毫米的环形肋片。肋片管的加工过程是将已套好肋片的导管,经过管子的胀管作用,使管外壁与肋片紧密贴合;从而使肋片对管壁有良好的导热性能。肋片管道采暖的主要特点是:打破过去输送热媒管道与散热器分离的传统做法,使肋片 I. Overview Tianjin Construction Design Institute and Tianjin Construction Bureau mechanical and electrical installation company jointly created high-temperature water finned pipe heating. As a concrete method for conveying and cooling the finned tube, a φ38×3 seamless steel pipe is used as a pipe, and a 1 mm thick annular rib is inserted outside the pipe. The process of finned tube is to fit the ribbed tube through the expansion tube of the tube, so that the outer wall of the tube and the fins are in close contact with each other, so that the fins have good thermal conductivity to the tube wall. The main features of the heating of the finned pipe are: to break the traditional method of separating the heat transfer pipe from the radiator and to make the ribs
