摘　　要：基于拓扑优化方法,研究复合目标函数、权重因子、流道体积分数对液冷板性能的影响,研究结果表明:以液冷板固体区域平均温度和流体功率耗散加权的复合目标函数优化结果较佳,在该目标函数下,权重因子为0.75和体积分数为0.50时可以得到最佳拓扑优化的设计参数;与传统直通道液冷板相比,在不同流速下,拓扑优化液冷板的平均温度、最高温度和温差分别降低0.86℃、0.89℃和1.12℃,在维持锂电池温差5℃下拓扑优化液冷板压降下降56.7%。Based on the topology optimization method,the influence of composite objective function,weight factor,and channel volume ratio on the performance of liquid cooling plates is studied.The research results show that using a composite objective function weighted by the average temperature of the solid region of the liquid cooling plate and the power consumption yields can achieve better optimization results.Under this objective function,the optimal topology optimization design parameters are a weight factor of 0.75 and a volume fraction of 0.50.Compared with traditional liquid cooling plates with straight channel,under different flow rates,using the topology-optimized liquid cooling plates,it can reduce the average temperature,maximum temperature,and temperature difference by 0.86℃,0.89℃and 1.12℃,respectively.While maintaining a battery temperature difference of 5℃,the pressure drop of the topology-optimized liquid cooling plate decreases by 56.7%.
