摘要 为了优化电池组的冷却性能,提出了一种均匀直通道与阵列翅片相结合的液冷板设计。基于计算流体动力学(CFD)的评估方法对模型进行冷却性能分析和优化,在5 C放电工况下,研究对液冷板内部不同的通道与阵列翅片组合形式、进出口宽度、翅片大小和上下冷却槽间距对电池热管理的影响。结果表明:中间使用翅片、两侧使用通道可以改变最高温度、平均温度和温差,改变进出口宽度可以显著改变进出口压降。与原始模型相比,质量流量为0.5 g/s时,优化模型满足最高温度为39.99℃,平均温度降低0.93℃,同时温度标准差和进出口压降分别降低0.09℃和494.68 Pa;冷却液质量流量对液冷板散热性能有一定程度的影响。 A liquid cooling plate with uniform straight channel and array fins was proposed to optimize the cooling performance of battery pack.Based on the evaluation method of the computational fluid dynamics(CFD),the cooling performance of the established model was analyzed and optimized.It was investigated under 5 C discharge condition that the effects of different combination forms of channels and array fins in the liquid cooling plate,inlet and outlet width,fin size and the spacing between upper and lower cooling tanks on battery thermal management.The results show that the use of channels on both sides of the middle fin can change the maximum temperature,the average temperature and temperature difference,and the inlet and outlet width significantly change the inlet and outlet pressure drop.Compared with the original model,when the mass flow rate is 0.5 g/s,the optimization model meets the maximum temperature of 39.99°C,the average temperature is reduced by 0.93°C,while the temperature standard deviation and inlet and outlet pressure drop are reduced by 0.09°C and 494.68 Pa,respectively;the coolant mass flow rate has a certain degree of influence on the heat dissipation performance of the liquid cold plate.
