摘　　要：分离式热管散热器具有小温差下的高效传热能力,可在一定条件下替代室内空调系统,以达到节能减排的目的。针对分离式热管散热器的应用之需,根据两相流理论和R22工质的热力学性质,建立了最佳充液率的理论模型,进行了最佳充液率的计算及实验研究,分析了不同充液率下蒸发器和冷凝器管壁温度分布的实验结果,讨论了在常温小温差条件下水平布置分离式热管散热器的最佳充液率范围。Aiming at the application study of the indoor heat dissipation of the separating heat pipe,and using the high efficiency heat transfer,traditional air conditions can be replaced by separating heat pipe radiators,for reaching the purpose of energy conservation.Combining the theoretical analysis of the heat dissipation′s performance of the heat pipe,it was built to a simplified model which described the normal working of the separating heat pipe.It was also be study by experimental study to the performance of the heat transform.The performance is contacted with the filling rate of separating heat pipe.Analyzed temperature distributions of the tube wall of the evaporimeter and the condensator at the different filling rates,the best filling rate range was be acquire in this heat pipe structure accommodating the normal temperature and the small temperature difference.This filling rate range aims to get the best heat dissipation.
