热环是泵或风机驱动的动力型分离式热管的简称，它为解决非相邻冷热源间的强化传热问题提供了一种较理想的解决办法。本文对热环的循环工质、驱动方式、性能系数进行了初步理论分析，并对气相驱动方案进行了验证性实验。最后，对热环与非分离式热管、重力型分离式热管、水回路方法在非相邻冷热源间热量传递中的应用特点进行了比较分析
Heat circuit is the abbreviation of separate type heat pipe propelled by a pumpor fan. It supplies a suitable method for heat transfer between non-adjacentheat source and heat sink. In this paper, the cyclic fluids, propelling typesand performance of heat circuit are analyzed and some basic conclusions of afan-propelled heat circuit are experimentally tested. At the end, the potentialof its application in industry is commented
