热管是在较小温差下传送大热量的导热元件,尤其是在气——气换热时,热管加热段和冷凝段都可进行肋化,扩展表面,热管式换热器,其传热系数K值能达268kcal/m~2·h·℃,而常规用一般管式换热器K值仅达20kcal/m~2·h·℃。因此,研究及合理地设计热管换热器,用于余热回收,将显示出其独特优点。1981年4月份起,我们开始了热管换热 Heat pipe is a heat transfer element that transfers large heat at a small temperature difference. Especially in the gas-gas heat exchange, the heat pipe heating section and the condensing section can be ribbed, and the surface of the heat pipe heat exchanger is improved. The heat transfer coefficient K value can reach 268kcal / m ~ 2 · h · ℃, while the conventional use of conventional tubular heat exchanger K value of only 20kcal / m ~ 2 · h · ℃. Therefore, research and rational design of heat pipe heat exchanger for waste heat recovery, will show its unique advantages. Since April 1981, we started heat pipe heat exchange
