本文对我国分离式热管技术的研究进行了简要概况。针对工程中热源在上、冷源在下及冷热源相距较远时的热量传递问题 ,在分析了一般分离式热管及“水回路”等技术的基础上 ,对一种新型分离式热管———泵或风机驱动的动力型分离式热管 (简称热环 )的研究进行了小结和展望 This article gives a brief overview of the research on the separate heat pipe technology in our country. In view of the heat transfer problem when the heat source is in the upper and the cold source is far apart from the cold and heat source, based on the analysis of the general separation heat pipe and the “water circuit” and other technologies, a new type of separation heat pipe - - Pump or fan-driven power split heat pipe (referred to as the hot ring) of the research summary and prospect
