摘要

高效的热管理系统能极大提高电池使用寿命并保证电池安全运行。为提高能源利用效率，针对动力电池组散热问题设计了基于相变材料的被动式热管理系统。采用泡沫铜/石蜡构成复合相变材料以提高石蜡的导热性能，并对复合相变材料导热性能进了测试。通过改变孔隙率、加热功率及环境温度，对不同工况下基于复合相变材料的热管理系统性能进行了实验研究。实验结果表明，泡沫铜孔隙率分别为96%、95%以及93%的复合相变材料的热导率分别是纯石蜡的14.2倍、19.2倍和25.4倍。基于复合相变材料的热管理系统能显著降低热源温度，其冷却性能优于自然对流风冷热管理系统。当热源发热量及环境温度为定值，相同结构复合相变材料下，泡沫铜孔隙率越低，热管理系统性能越好。基于复合相变材料的热管理系统能显著减小由于加热功率和环境温度变化导致的温度波动，提高了热源温度稳定性。

Abstract

An efficient thermal management system (TMS) can significantly improve the battery life and ensure the safe operation of the battery. In the paper

a passive thermal management system based on phase change material (PCM) was designed to solve the battery heat dissipation. The composite PCM using paraffin and foam copper was employed to improve the thermal conductivity of the PCM and the experimental research on the conductivity of the composite PCM. The performance of the TMS with the composite PCM was investigated by the change of the porosity

heating power and ambient temperature. The results showed that the thermal conductivities of the composite PCM with porosity of 96%

95% and 93% were 14.2 times

19.2 times and 25.4 times as much as that of the pure paraffin

respectively. The TMS with composite PCM significantly reduced the temperature of the heat source and its performance was superior to the natural convection cooling. Under the conditions of the fixed heating power and the ambient temperature

the maximum temperature of the heat source declined with the decrease of the porosity. In addition

the TMS of the composite PCM can significantly reduce the temperature fluctuation caused by the change of the heating power and the ambient temperature

and improve the temperature stability of the heat source.
