热管启动性能研究进展

Advances in study of start-up performance of heat pipes

热管作为一种高效的被动式传热元件,以其自身独特的优势在化工、航天、能源和动力等领域中得到了广泛应用。热管启动性能既是热管的重要技术参数,也是热管瞬态特性的组成部分。对近10年来关于常规热管、温控热管、小型/微型热管、环路热管、脉动热管的启动性能研究进行了综述,并对影响热管启动性能的因素开展了分析和讨论。

Heat pipes are passive heat transfer devices with high thermal conductivity. Due to their own advantages,heat pipes are widely used in chemical industry, aerospace, energy and power engineering, etc. Start-up performance is not only an important technical parameter for heat pipes, but also one of characteristics of transient state of heat pipes. Studies on start-up performance of conventional heat pipes, temperature controlled heat pipes, miniature/micro heat pipes, loop heat pipes and pulsating heat pipes in the past decade are reviewed. Influencing factors of start-up performance of heat pipes are also analyzed and discussed.
