摘　　要：针对目前电池热收缩通道热量损耗严重、包装质量不高的缺点,采用Fluent对现有热收缩通道内部流场进行三维数值分析,研究通道内部关键部位流场,提出改进方案并进行相应实验验证。仿真结果表明:温度和风速在通道内关键部位截面温度和风速分布不合理且平均温度和风速低于实际加工要求,基于仿真结果,通过改进出风口、回风口及加热元件位置等方式,通道内流场分布合理性得到很大提高,实验结果表明,改进后热收缩通道包装效果得到一定提升,热量损耗有所降低,结果符合预期。In view of the serious heat loss and low packaging quality of the thermal shrinkage channel of the battery at present, the three-dimensional numerical analysis of the flow field in the existing thermal shrinkage channel is carried out by using Fluent, the flow field in the key parts of the channel is studied, and the improvement scheme is put forward and the corresponding experimental verification is carried out. The simulation results show that the cross section temperature and wind speed distribution of temperature and wind speed in the key parts of the channel are unreasonable and the average temperature and wind speed are lower than the actual machining requirements. Based on the simulation results, the rationality of the flow field distribution in the channel is greatly improved by improving the air outlet, returntuyere and heating element position. The experimental results show that the packaging effect of the improved thermal shrinkage channel is greatly improved. The result was improved and the heat loss was reduced, and the results met the expectations.
