摘要
采用Fluent软件,对混合动力客车的电池包在现有的自然通风散热系统下的温度场分布进行了仿真,并通过实车实验验证了仿真模型的正确性。针对现有散热系统存在的空气流量不足以及流动阻力过大的问题,提出了三条优化措施。以上述经过实验验证的模型为基础,建立了多个不同模型,对三条优化措施的冷却效果分别进行了模拟,证明了这些措施的有效性。
The temperature distribution in battery pack, which is cooled by natural wind on the hybrid electric bus, is simulated by the CFD software Fluent and the corresponding experiment is taken to prove the validity of the simulation. According to the defect of low mass flow rate and high flow resistance in current cooling system, three ways of optimization are provided. Based on the simulation model which is proven by the experiment above, several models are established to test the effect of these three ways. The result shows that they work substantially well.
