为了更有效地回收和利用余热,日本通产省工业技术院组织政府和民间研究机构研究余热回收利用技术。在研究热回收、热交换、热输送、热储存等各种单项技术的基础上,设计出合理利用余热的综合系统。热回收和热交换技术的具体内容及目前进展情况如下。 1.回收低温余热的热管热管,是一个封闭的管状元件,管壳用铜或不锈钢制成,抽真空后充以工作液(水或氟里昂、氨、甲醇、 In order to recover and utilize waste heat more efficiently, the Japan’s MIIT Institute of Industry and Technology organizes government and private research institutes to research waste heat recovery technologies. On the basis of studying a variety of individual technologies such as heat recovery, heat exchange, heat transfer and heat storage, a comprehensive system of rational use of waste heat is designed. The specific content of heat recovery and heat exchange technology and the current progress are as follows. 1.Recovery of heat pipe heat pipe heat, is a closed tubular components, the shell is made of copper or stainless steel, after the vacuum filled with working fluid (water or freon, ammonia, methanol,
