摘要
基于ANSYS平台,通过恰当的工况分解,对热电池激活及放电全过程传热和温度变化规律进行了深入分析。构建的仿真模型全面考虑了激活及放电过程的不同热源分布,包括加热片发热、电解质相变热、焦耳热和电化学反应热,能够较为精准地预测热电池各局部温度分布及变化趋势,并反映热设计所达到的效果。通过与实测数据对比,表明该仿真模型具有较高的准确度。
Based on ANSYS platform,heat transfer and temperature variation regularities of thermal battery during activation and discharge were analyzed in depth through proper condition decomposition.Different heat sources during activation and discharge were took into account in the simulation model,including the heat of pyrotechnic pellet,phase change heat of electrolyte,Joule heating and chemical reaction heat.The model could be applied to accurately predict the temperature distribution and variation trend of the local in thermal battery,and effectively reflect the effect of thermal design.It could be found that the simulation model had relatively high precision compared with the experimental results.
