| 摘 要： | 针对车用锂离子动力电池的散热问题,对电池组的结构进行优化设计。建立锂离子动力电池三维模型,利用Fluent进行数值仿真。通过对仿真结果的对比分析得出：电池间距的增大和减小分别使电池组的散热性能提高和降低,且其间距减小时,电池间温度差异明显;发现动力电池组入口风速升高,电池表面空气流速相对提高,电池组换热能力增强,但电池间流场的一致性变差、温差变大。 |

| Abstract: | As to the heat dissipation issues lithium-ion power battery for vehicles,the structure of the battery pack is optimized. Building lithium-ion battery three dimensional model and simulating by fluent software. The comparison and analysis on simulation results show that the battery space of the battery pack is increased and decreased, respectively, the thermal performance of battery pack is raised and fallen. Moreover, the space is reduced,the temperature difference among batteries is obvious.Air velocity is increased on the surface of battery and the heat exchange capacity of the battery pack is raised when the inlet velocity of battery pack rises.However, the consistency of the flow field between the batteries become bad, the temperature difference becomes larger. |
