摘　　要：提出了一种新型槽道式平板热管均热器.这种新型结构能使平板热管均热器具有较强的轴向和径向导热能力。并且能在反重力条件下工作.通过实验验证了其良好的性能,得到了最佳充液量.通过比较平板热管与铜板扩散热阻计算值,得到了平板热管的适用条件.In this paper, a novel grooved flat plate heat pipe（FPHP） was designed. The grooved structure of the FPHP can improve its axial and radial heat transfer and also can form the capillary loop between condensation and evaporation surfaces. Prom experiment, we also obtained the best filling amount of this grooved FPHP. By comparing the thermal resistance of a solid copper plate with that of the FPHP, it is suggested that the critical heat flux condition should be maintained to use FPHP as efficient thermal spreaders for electronics cooling.
