过高和过低的温度会显著降低动力电池的性能。为了延长电池的循环寿命，进而提高电动汽车的性能，设计了一种振荡热管（OHP）冷却的电池热管理（BTM）系统，并对其进行了实验研究。结果表明，电池的高温段应靠近过氧化氢的冷凝段。OHP不应水平放置，以减少OHP内工作流体的回流阻力。OHP的启动温度由电池的期望最高温度和可接受的最大温差决定。所得结论可为基于OHP的电池热管理系统的设计提供参考。
Excessive high and low temperature can significantly reduce the performance of power battery. To extend the cycle life of battery and then improve the performance of electric vehicles, an oscillating heat pipe (OHP)-cooled battery thermal management (BTM) system was designed and experimentally studied in this paper. The results showed that the higher temperature section of battery should be near the condensation section of OHP. The OHP should not be placed horizontally in order to reduce the reflow resistance of the working fluid within OHP. The start-up temperature of OHP is determined by the desired maximum temperature and the acceptable maximum temperature difference of the battery. The conclusions can be used as reference for the design of OHP-based battery thermal management system.
