摘　　要：针对径向偏心重力热管的结构特征,分析其传热过程和传热特性;以传热热阻分析的方法,推导各热阻的计算公式,并重点推导径向偏心重力热管内管外壁面的凝结换热系数,得到了径向偏心重力热管内管外不同角度下管外凝结换热系数的规律,从而揭示了径向偏心重力热管的传热特性.In accordance with the special structural characteristics of the radial eccentric gravity heat pipe,its heat transfer processes and heat transfer features are analyzed by the thermal resistance analysis method for the heat transfer,the formulas for calculating the thermal resistance were derived,with emphasis on the derivation of the condensation heat transfer coefficient on the outer side surface of the inner tube of the radial eccentric gravity heat pipe.The condensation heat transfer coefficient of the radial eccentric gravity heat pipe under different angles between the inner and outer tubes was obtained.Thus,the heat transfer characteristics of the radial eccentric gravity pipe were revealed.
