一、国内简况我国热管研究工作开始于七十年代初,主要是从1977年起,中国科学院工程热物理研究所,航天部飞行器总体设计部南京化工学院,重庆大学、成都建工学院、哈尔宾工业大学、哈尔宾空调厂,河南商丘市等单位,陆续开展了热管用于节能工程的开发性研究。几年来,我国已经研制成功了铜—水热管(即以水为工质、铜材为壳体的热管),纯合金钢—水热管,铝—氨热管,铝—丙酮热管,铜—丙酮热管,碳钢—水热管等多种可用于回收余热的热管换热器(150°—400℃的烟气余热和80°—150℃工业废气的余热)(而日本用热管回收烟气余热时,其温度最高也只为430℃)并于1980年,在南京炼油厂、抚顺石油工厂、河南商丘市农机厂,以及商丘市能源研究所等单位,首先把热管换热器应用于烟道气余热回收,取得预期的效果。
First, the domestic profile China’s heat pipe research began in the early seventies, mainly since 1977, the Institute of Engineering Thermophysics, Chinese Academy of Sciences, the Ministry of Aerospace General Design Department of Nanjing Institute of Chemical Industry, Chongqing University, Chengdu Institute of Technology, Hal The Binh Polytechnic University, Harbin Air Conditioning Plant, Shangqiu City, Henan Province and other units have successively carried out the development of heat pipes for energy-saving projects. Over the past few years, China has successfully developed a copper-water heat pipe (that is, a heat pipe using water as a working medium and copper as a shell), a pure alloy steel-water heat pipe, an aluminum-ammonia heat pipe, an aluminum-acetone heat pipe, and a copper-acetone heat pipe. , carbon steel - water heat pipe and other heat pipe heat exchangers that can be used to recover waste heat (flux from 150°C to 400°C and waste heat from 80°C to 150°C industrial waste gas) (while Japan uses heat pipe to recover waste heat from flue gas, The highest temperature was only 430°C. In 1980, the heat pipe heat exchanger was first applied to flue gas waste heat in units such as Nanjing Refinery, Fushun Petroleum Plant, Henan Shangqiu Agricultural Machinery Factory, and Shangqiu Energy Research Institute. Recycling to achieve the desired effect.
