摘要
本文对回路型脉动热管（Ｌｏｏｐｅｄ ＰＨＰ）的运行进行了可视化实验研究，观察了其稳定运行时，工质的运动特征和热管内的典型现象；研究了其传热性能与充液率，冷却方式，加热端与冷却端相对位置等各种因素的关系；在可视化实验结果的基础上，对脉动热管运行的一些基本问题进行了讨论和分析。
Flow of looped pulsating heat pipe was studied by a visualized experimental method in this work. When running stably, flow character of working fluid and typical phenomena in PHP was observed. And the relations between heat transfer rate and charging ratio, cooling, method, relative position of heating end and cooling end etc was investigated; On the basis of experimental result, some elemental problem about running of PHP was discussed and aanalized.
