摘　　要：对无吸液芯偏心径向热管进行了实验研究,在不同加热热流密度、充液率和工作温度下测量了偏心径向热管换热性能.结合偏心径向热管内特殊的结构和热管换热机理,分析了偏心径向热管换热特性产生的原因.最后采用多元线性回归方法分析了径向热管的当量内热阻关系式,为工程设计和应用提供了依据.The experiment of radial eccentric heat pipes without wick is carried out. The heat transfer performance is tested in different heat fluxes, liquid full ratios and operation temperatures. The characteristic heat transfer performance is analyzed from the angles of both the special structure and the heat transfer mechanism. At last, the unit thermal resistance empiric relation is regressed by multiple linear regression method, which will provide reference for engineering applications.
