流动风阻网格模型与热仿真设计方法优化动力电池模组结构的研究
摘要：摘要风冷系统因结构简单、成本低等特点,在热管理系统中占据重要地位。目前常规的风冷热管理设计方法存在重复性工作多、设计时间长的缺点。本文提出空气流动风阻网格模型结合热力学模型仿真的设计方法,先采用空气流动风阻网格模型获得优化的电池结构,再采用热力学模型进行仿真求解,获得优化的电池模组的流场和温度场分布特性。仿真结果验证了优化结构的准确性。优化结果表明,C字形结构更有利于提升模组内单体电池冷却效果的一致性,并且优化后的C字形结构进一步提升了电池模组内单体电池温度场的一致性。此外,计算结果发现模组内空气流动方向为上进下出时可进一步降低模组内单体电池的最高温度,提升单体电池温度场的一致性。
Abstract:：Air cooling system plays an important role in battery thermal management system (BTMS) because of its simple structure and low cost. The conventional design method of air cooling and heat management has the disadvantages of repetitive work and long design time. In this paper, a design method based on air flow resistance network and thermal simulation was proposed. Air flow resistance network was firstly used to optimize the module structure, and then thermal simulation was used to calculate the flow distribution. Temperature distribution of battery module, and the accuracy of optimization was verified by the thermal simulation result. It was found that flat C shape structure was more conducive to improving the temperature consistency of battery module, and the optimized C shape structure can improve the temperature consistency further. The calculation results showed that upper-lower flow direction can reduce the maximum temperature and improve the temperature consistency.
