Description

一种动力锂电池用浸没式散热冷却液及其制备方法
本专利申请要求2018年1月22日提交的中国专利申请号为201810057912.0，申请人为上海宸海科技集团有限公司，发明名称为“一种动力锂电池用浸没式散热冷却液及其制备方法”的优先权，该申请的全文以引用的方式并入本申请中。
技术领域
本发明涉及的是化工领域，具体涉及一种动力锂电池用浸没式散热冷却液及其制备方法。
 背景技术
随着新能源汽车的快速发展，动力锂电池的应用更加广泛，但同时也面临一系列急需解决的问题，比如由于电池发热导致其寿命减少、可靠性及安全降低等。锂电池散热技术主要包括间接散热冷却技术和直接冷却技术，现有的动力锂电池主要采用的是自然冷却、风冷、管道式液体冷却等间接的散热模式，此类散热技术在一定程度上可以缓解电池的散热问题，但是不足以满足高热流密度动力锂电池组的散热要求，其缺点明显，传热过程复杂，存在接触热阻及对流换热热阻，热阻总和大，换热效率低，同时可能导致内部热量叠加，从而导致电池组内的温度越来越高，最终直接影响电池组的使用寿命及安全性。此外，一些动力锂电池如电动汽车用动力锂电池使用环境恶劣、使用频率高，对锂电池组要求更加严格，要求电池组内温度场均匀，间接式散热冷却技术难以满足其散热需求。直接冷却技术主要采用的是浸没冷却技术，即将整个电池组完全浸没在冷却介质中。根据冷却介质沸点的不同，分为相变浸没冷却和单相浸没冷却。相变浸没冷却是通过冷却介质在电池组发热处蒸发为气态上升至密闭空间的上方，与上方的换热器换热重新冷却为液体完成循环；单相浸没冷却通过介质泵完成循环，实现热量的交换。浸没式直接冷却由于其冷却介质比热大，散热速度快，制冷效率远高于间接散热冷却技术。在浸没式冷却技术中，相变冷却由于是利用制冷剂沸腾时的汽化潜热带走热量，汽化潜热比冷却介质比热要大很多，因此其蒸发冷却的冷却效果更为显著。
