| 摘 要： | 本文对电池模块浸没式油冷散热方案进行了仿真研究,分析电池成组后大容量电池模块的散热特性,获得了导热阻燃硅油流量参数对大容量电池组散热的影响规律。研究表明,浸没式油冷能有效控制大容量电池模块的温升;改变流量可以提升换热效果,但对电池模块的最高温度及温差控制具有局限性,由于电池箱存在流动死区,换热效果更易受到硅油热导率的制约。

| Abstract: | In this paper,the battery module with immersion silicone oil cooling is simulated.The heat dissipation characteristics of the modules are analyzed,and the influence of flow parameters of heat-conducting and flame-resistant oil on the heat dissipation of the modules is introduced.The results show that the temperature rise of battery modules can be effectively controlled by means of immersion oil cooling.It is observed that changing the flow rate can improve the heat exchange effect,but immersion oil cooling has limitations on the maximum temperature and temperature difference control of the battery module.Due to the dead flow zone in the battery box,the heat transfer effect is more easily restricted by the thermal conductivity of silicone oil. |
