中文摘要：

本文设计了一极端工况，即在太空环境内有一热流密度为100W／cm^2的发热器件。借助于三维数值模拟方法对液体金属不同流道的散热能力进行了评估。结果表明，该工况下，综合液体金属利用率及管道内流动阻力等因素，II型管道可实现较好的散热能力。进一步，文本设计了具有相同散热流道横截面积的‘倒T’型流道，并进行流动方向的参数化研究，结果表明，“倒T”型流道内的分散交错流动可针对该极端工况实现良好的散热及均温能力。

英文摘要：

Evaluation on liquid metal heat dissipating heat flux 100 W/cm2 in space environment, was carried capacity in an extreme working condition, a out by 3D numerical simulation. As a result, channel II proposed in this paper is provided with an outstanding performance while taking various factors into the consideration. Furthermore, parametric studies were implemented on the ＂Inverted T＂ channel with same cross-section area channel took on a great heat dissipating working condition. Finally, scattered and reverse flow in such ＂Inverted T＂ and temperature equilibrium capacity for the extreme
