アニュラー型回転ヒートパイプの水平姿勢における作動液流動と熱輸送特性 : 第2報,各種伝熱条件に対する伝熱実験と理論解析

Heat transfer efficiency of annular-type heat pipes is investigated experimentally and theoretically, for the evaporating section and condensation section respectively. The heat transfer coefficients of evaporating liquid film are obtained under several conditions of the annular gap, charged volume rate of the working fluid, wall superheating and rotational speed. It is shown that the results of theoretical analysis for condensation heat flux agree well with experimental results, and also that the taper angle of the condensation wall greatly influences on the heat transfer efficiency.
