Study on the feasibility and structural optimization of heat-pipe on board

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 a effective length of 0.12m is as large as -1.2g which can conquer the disadvantages of the acceleration and change of azimuth when the plane manoeuvres. At the same time the heat transfer capability of the heat-pipe is as high as 10w/cm2 with a temperature difference as low as 15.303K which can meet the demand of large flow heat transfer on board completely.
