摘　　要：系统地研究小充液率条件下重力对微槽平板热管传热性能的影响,分析了工作温度、冷却方式等影响因素.发现重力对热管径向液膜的分布影响比较小,而对轴向的影响比较明显,从而使得倾角较大地影响了热管的传热能力.进一步证明了深槽平板热管具有良好的传热性能.The influence of the gravitation on the thermal performance of the flat miniature heat pipe with small charge ratio is studied systematically and the influence of the working temperature and cooling method are also analyzed. The conclusion can be reached that the gravitation influence is ob-(vious in) the axially direction while it is negligible in the radial direction, which results in the great influence of tilt angle on the performance of the flat miniature heat pipe. It is proved that the flat miniature heat pip with deep and narrow grooves has excellent heat transfer performance in the field of small-room heat dissipation, such as the cooling of micro electronic apparatus.
