摘　　要：为了解决军用电子设备高热流密度器件的散热问题,设计了一种机械泵驱动两相流冷却系统,对该系统在加速度环境条件下的热性能进行了测试。通过实验数据与现象分析,在加速度环境条件下,储液分液器将不能正常工作,内部液体容易在某部位聚集而不能在管路中循环流动而导致失效。本文通过提高系统充液量的方式来解决该问题,试验结果表明,提高系统充液量后,系统在加速度环境条件下正常工作。In order to solve the heat dissipation problem of high heat flux devices in military electronic equipment, a two-phase flow cooling system driven by mechanical pump is designed in this paper, and the thermal performance of the system is tested under the conditions of acceleration. Through the analysis of experimental data and phenomena,under the condition of acceleration environment, the reservoir will not work normally, and the internal liquid is easy to gather in a certain part and can not circulate in the pipeline. In this paper the problem is solved by increasing the liquid filling capacity. The test results show that the system works abnormally in acceleration environment after the liquid filling capacity is advanced.
