一、热管的应用与发展自从美国1976年首先应用热管以来,热管换热器用于热能回收就逐渐引起各国重视,近年来在日本、西德等国已普遍推广应用。并已达到商品化,1981年日本化工成套设备已展览出一种旋转式热管,可以回收150℃—300℃中低温度废汽的热能,用以予热供燃烧用的空气回收蒸汽。该换热器的热管以圆型隔板中心为轴而旋转,传热效率比一般热管换热器高。1979年至1980年日本设计制造了以20,000[标米~3/时]200℃—350℃的废气,回收20万(千卡/时)热管
First, the application and development of heat pipe Since the United States in 1976 the first heat pipe, heat pipe heat exchanger for heat recovery gradually attracted the attention of all countries, in recent years in Japan, West Germany and other countries have been widely promoted. And has reached commercialization. In 1981, Japan’s chemical plant has exhibited a rotating heat pipe that can recover the heat energy of low-temperature waste steam at 150 ℃ -300 ℃ to preheat the air used for combustion to recover steam. The heat pipe to the center of the round baffle plate as the axis of rotation, heat transfer efficiency than the average heat pipe heat exchanger. From 1979 to 1980, Japan designed and manufactured exhaust gas at 20000-350 ° C at a rate of 20,000 m 3 / h, recovering 200,000 kcal / h heat pipes
