新能源汽车动力电池的冷却结构对于确保电池在各种工作条件下保持适宜的工作温度至关重要。高效的冷却系统不仅有助于延长电池寿命，还能提升车辆的安全性和性能。文章分析冷却技术对动力电池的影响、电池冷却技术的发展及动力电池冷却结构的设计要求。针对现有冷却结构的技术缺陷，本文设计开发了一种新型新能源汽车动力电池冷却结构，解决在动力电池振动清洁时，需依次驱动两套滤网组件且清洁效率低的问题，提高冷却效率。

The cooling structure of the power battery in new energy vehicles is crucial for ensuring that the battery maintains an appropriate working temperature under various working conditions. An efficient cooling system not only helps to extend battery life but also enhances the safety and performance of the vehicle. The influence of cooling technology on power batteries, the development of battery cooling technology and the design requirements of power battery cooling structures were analyzed. In response to the technical deficiencies in the existing cooling structure, a new type of cooling structure for the power battery of new energy vehicles has been designed and developed, which solves the problem that two sets of filter screen assemblies need to be driven in sequence during the vibration cleaning of the power battery, resulting in low cleaning efficiency of the filter screen assemblies, and improves the cooling efficiency.
