摘　　要： 通过对矩形沟槽式圆形微热管的结构、强度和传热极限的各种影响因素进行分析和推导,分别建立了矩形沟槽式圆形微热管的黏性极限、声速极限、携带极限、毛细极限、冷凝极限、沸腾极限、连续流动极限和冷冻启动极限的模型,并通过实验验证了所建立的传热模型的正确性。 By analyzing and deducing the factors influencing its structure, strength and heat transfer limits,this paper was to establish the heat transfer models of circular micro heat pipe with a rectangle- grooved wick structure, including the models of viscous limit, sonic limit, entrainment limit, capillary limit, condensing limit, boiling limit, continuous flow limit and frozen startup limit. It was also to establish the model of strength theory and to testify by means of experiments the correctness of the heat transfer models thus built. The study lays a powerful theoretical foundation for the design and manufacture of circular micro heat pipe with a rectangle--grooved wick structure.
