摘要
基于新型锂离子储能系统的热管理需求,对其散热结构进行优化设计。通过分析电池热特性,提出一种结合风冷、液冷和相变材料的组合散热结构,构建多层次热管理系统。实验结果表明,该结构在高能量密度场景下表现出显著优势,散热效率达91.5%,电池间温差控制在±2℃,满足安全运行要求。
Based on the thermal management requirements of the new lithium-ion energy storage system,the heat dissipation structure is optimized and designed.By analyzing the thermal characteristics of the battery,a combined heat dissipation structure integrating air cooling,liquid cooling and phase change materials is proposed to construct a multi-level thermal management system.The experimental results show that this structure exhibits significant advantages in high energy density scenarios.The heat dissipation efficiency reaches 91.5%,and the temperature difference between batteries is controlled within±2℃,meeting the requirements for safe operation.
