径向式热管与重力式热管管壁温度的影响因素分析

摘要

阐述了热管进行锅炉烟气余热回收时,管壁温度的控制对于防止低温腐蚀的必要性,文章计算分析了管径、翅片长度、翅片厚度、翅片间距、冷流体入口温度等因素对于管壁温度的影响规律.分析认为增加热管管径、减小翅片间距,可以适当提高壁温.%This paper stresses on the necessity of pipe wall temperature control to prevent low temperature corrosion. It calculates and analyzes the influence of the factors such as tube diameter, fin length,fin thickness,fin space and inlet temperature of cold fluid on pipe wall. The tube diameter of the heat pipe is increased, the fin space is reduced and the wall temperature is increased properly. It provides reference for the field application.
