Simulation study on optimization of temperature control performance of energy storage battery cluster by liquid flow cooling

为了提高储能电站中电池簇的散热效果、改善电池表面温度分布的不均匀性,本文按照实际尺寸建立了电池簇的液冷仿真模型。利用Fluent仿真软件研究了出水口布置在不同位置时的散热效果,选定了最佳的布置方案,最大温差由16 K降低到13 K,降低了18.8%。进一步研究分析了冷板布置在底面和侧面时的散热效果,结果表明,采用冷板布置在电池侧面的方案,电池表面温度分布的不均匀性得到改善,最大温差由13 K减小到3.7 K,减小了71.5%,温差被控制在规定范围内。

In order to improve the heat dissipation effect of the battery cluster in the energy storage power station and the uneven temperature distribution of the battery surface,a liquid cooling simulation model for the battery cluster was established according to the actual size.Fluent simulation software was used to study the heat dissipation effect when the water outlet was arranged at different positions,and the best arrangement scheme was selected.The maximum temperature difference was reduced from 16 K to 13 K,which was reduced by 18.8%.The heat dissipation effect of the cold plate on the bottom and side of the battery was further studied and analyzed.The results show that the non-uniformity of the temperature distribution on the battery surface is improved by using the cold plate on the side of the battery,and the maximum temperature difference is reduced by 71.5%from 13 K to 3.7 K,and the temperature difference is controlled within the specified range.
