摘要

针对热管用于机载设备散热的可行性和实际性能进行了分析计算

并对机载热管进行了优化设计

结果表明:有效长度为0.12m的微槽道平板热管沿轴向抗反向加速度能力达-1.2g

完全可以克服大型飞机机动飞行时加速度和方位角变化对热管工作的不利影响

经过优化

此时热管的传热能力达10W/cm2

传热温差仅15.303K

完全可以满足机载设备大热流密度散热的需求.

Abstract

The feasibility and capability of heat-pipe on board was studied by analysis and computation

and the structure was optimized.The results show that the capability of anti axial acceleration of heat-pipe with an effective length of 0.12m is of -1.2g

helping to conquer the disadvantages of changing acceleration and azimuth when the plane manoeuvres.At the same time

the heat transfer capability of the heat-pipe is of 10W/cm2 high with a temperature difference of only 15.303K

so it can meet completely the demand of large flow heat transfer on board.
