摘要
对锂离子电池的产热模型和散热技术进行综述,介绍目前锂离子电池领域风冷、液冷、相变冷却及复合冷却的发展情况。风冷效果的优化主要从冷却介质参数、结构参数及控制策略方面进行;液冷技术出现了散热能力强的微流体冷却,有望实现外部冷却到内部冷却的技术革新;相变冷却技术引入液气相变技术,实现了热量快速传递,可满足高倍率放电高散热量的需求;复合冷却技术将主动冷却与被动冷却结合,将传统冷却与新型冷却结合,可满足不同应用工况的需求。
The heat generation model and heat dissipation technology of Li-ion battery were reviewed.The current development of air cooling,liquid cooling,phase change cooling and hybrid cooling technology in Li-ion battery field was introduced,which provided guidance for the future development of heat dissipation technology.The optimization of the air-cooling effect was carried out from the perspective of parameters of the cooling medium,structural parameters and control strategies;microchannel cooling with high heat dissipation appeared in the liquid cooling technology,which could realize the technological innovation from external cooling to internal cooling of the battery;liquid-gas phase change technology was introduced in the phase change cooling technology,which could realize rapid heat transfer and meet the needs of large heat dissipation in high-rate discharge applications;the hybrid cooling technology combined active cooling and passive cooling technology,combined traditional cooling technology with new cooling technology,to meet the requirements of different application conditions.
