【摘要】 锂离子动力电池液冷热管理系统中，间接液基体系具有更广泛的应用，而其保证温度控制的关键部件是冷却板。本文所设计的铜管/铝板复合液冷板，研究了LiFePO₄锂离子动力电池模组液冷热管理系统的冷却效果。电池分别在3 C、4 C倍率下充放电；选取水作为冷却流体，冷却流体的进出口模式分别为二进二出、四进四出、六进六出模式；冷却流体入口流量分别为2 mL/s、4 mL/s、6 mL/s、8 mL/s、10 mL/s。实验结果表明，四进四出模式下、冷却流体流量为6 mL/s时，该液冷系统实现了在上述不同参数组合下的最优性能。该结果为进一步提高电池热管理系统的性能提供了重要的参考价值。更多还原

【Abstract】 In the thermal management system of lithium-ion power battery, the indirect liquid-based system has a wider application. The major component in this system to ensure that temperature is controlled is the cooling plate. In this paper, the cooling effect of LiFePO4 lithium-ion liquid battery thermal management system using copper tube/aluminum plate composite liquid cooling plate is explored. The LiFePO₄ lithium-ion battery module is at 3 C and 4 C charged-discharged rate, water is selected as coolant,and the import and export mode of coolant are two in/two out, four in/four out, six in/six out mode respectively. The inlet flow rate of the cooling water are 2 mL/s, 4 mL/s, 6 mL/s,8 mL/s and 10 mL/s, respectively. As shown in the experimental results, in four in/four out mode,when the flow rate of the cooling liquid is 6 mL/s, an optimum effect can be achieved under the above different parameter combinations, which provides an important reference for battery thermal management to further improving the working performance.更多还原
