本文从汽相通道V型槽道内液态工质的分布规律入手，对不同V型槽结构内液态工质的分布进行了分析，得到了汽相通道的温度分布规律以及V型槽结构与热管最大工作能力的基本关系，对热管在微重力条件下的工作特性进行了模拟计算，从理论上印证了实验中观察到的基本现象，并结合实验研究提出了优化热管内V型槽道结构的基本方案。
The distribution for liquid in varies V-shape groove is studied. Characteristicof temperature distribution in the vapor passage wall is got. Basicrelationship for the structure of the V-shape groove vs the maximum capacityof heat pipe is brought up. Modeling calculation is carried out for theoperation character of heat pipe under the zero-gravity condition. And thebasic phenomena observed in experiments are proved through theoretical analysis.Finally, in conjunction with experimental study, preliminary technique forV-shape structure optimization is put forward.
