高速飞行器处于严重的气动加热环境下，影响光学设备的正常工作。在此基础上，设计了一种微尺度高效换热器。利用VOF方法对槽道尺寸为1.2 mm ×1.2 mm的四种不同排列方式的矩形微槽道进行了沸腾换热的仿真研究，结果表明，微槽道长度对沸腾换热有很大的影响，分析得出了微槽道最优设计方案，并对微尺度高效换热器的最大制冷量进行了计算，为下一步结构优化提供了理论指导。

The high speed aircrafts are in severe aero-dynamic environment,which influence optical window’ s func-tions. Then,the author devised a kind of microchannel heat exchanger. This literature used VOF method to simulate the boiling heat exchange by four types of micro groove with different arrangement style of microchannel,while each single rectangle microchannel had 1.2 mm × 1.2 mm side area. The numerical simulation showed that the length of microchan-nel contribute significantly to the boiling heat exchange,and analyzed the optimal design of microchannel. The result pro-vided a theoretical guidance for structure optimization in further.
