In this paper, this paper studies the thermal management of composite phase change materials on the thermal performance of power batteries, Including the type of heat pipe, environmental temperature, discharge rate, number of heat pipes and composite phase change materials, etc. By changing the mechanical structure of the composite phase change material and the heat conducting copper tube, the influence of the thermal performance of the power battery was enhanced. In this paper, the thermal performance of the composite phase change material and the heat conduction copper tube was experimentally investigated. The results show that the heat dissipation effect of the high-rate (4, 5 C, transient) discharge of the power battery pack at different ambient temperatures (30, 35 °C ) does not increase with the increase of the usage, and the cooling effect has uncertainties. The temperature of the power battery pack under its operating conditions is higher than the temperature of the PCM (265.9 g) operating conditions generally.ln the case of changing the amount of PCM/foamed copper/porous heat pipe composite phase change material, when the coupling module of PCM/foamed copper/porous heat pipe composite phase change material is 343.7 g in different ambient temperature and different working conditions under experimental verification, the thermal conductivity of the phase change material is improved, the internal temperature difference can be reduced, and the heat dissipation efficiency is improved. It is superior to other coupling modules and has good heat dissipation performance. The coupling of the thermally conductive copper tube and the composite phase change material is feasible.
