为电池热管理系统（BTMS）开发了两个具有平行四边形和梯形蒸发器配置的超薄环路热管（ULHP）原型。探讨了它们的传热特性（包括临界工作角、启动特性、热阻和流动不稳定性）之间的差异，并与多方向下进行的实验进行了比较。这两种蒸发器配置对超高压超高压稳定运行的具体影响已得到充分认识。实验结果表明，两种超高压原型机在重力辅助有限的情况下都表现出了良好的性能，满足了多方位工作的需求。特别是，平行四边形结构通过更好地抑制流动不稳定性而表现出优越的抗重力性能，超高压超高压不仅可以在15°倾角下启动，而且传热能力随放置角度的衰退限制在4%以内。同时，根据超高压超高压稳定运行状态建立了合理的数学模型，预测值与实验结果吻合较好。
Two Ultra-Thin Loop Heat Pipe (ULHP) prototypes with parallelogram and trapezoid evaporator configurations were developed for battery thermal management system (BTMS). The dissimilarities between their heat transfer characteristics including the critical work angles, the start-up features, the thermal resistances and the flow instability were all explored and compared with experiments conducted under multi-orientations. The specific influences of these two evaporator configurations on the stable operation of ULHP have been fully acknowledged. The experiments results demonstrated that both the two ULHP prototypes displayed good performances with limited assistance from the gravity, meeting the demand of working under multiple orientations. Specially, the parallelogram configuration showed superior performance in resisting gravity by better suppressing the flow instability, the ULHP could not only start up under 15° inclination, but also the recession in heat transfer capability with placed angles was limited in 4%. Meanwhile, a reasonable mathematics model was established based on the steady operation state of ULHP, the predicted value fitted well with the experimental results.
