| 摘要: |
| 为分析钠硫电池加热模块的温升过程,分别基于三维瞬态导热方程和Weibull函数建立了加热模块的理论模型和试验温升数据的拟合模型,数值模拟了钠硫电池加热模块温升过程与瞬态温度分布,探讨Weibull参数对升温曲线的影响规律．结果表明：Weibull拟合模型能够精确描述加热模块的温升过程,可靠度较高;模块内部整体温升率随时间和距离模块中心的长度均呈非线性降低趋势；形状参数和尺度参数分别决定了分段温升和整体温升的效率,这为钠硫电池加热模块以及其他加热装置的优化设计提供参考． |

| Abstract: |
| In order to analyze the temperature rise of the heating module for sodium-sulfur battery, the theoretical model of the heating module and fitting model of the experimental temperature data were established on the basis of 3D transient heat conduction equation and Weibull function, respectively, and also the temperature rise process and the transient temperature distribution of heating module for sodium-sulfur battery were numerically simulated, and the effects of Weibull parameters on the temperature rise curve were further investigated. The results indicate that the Weibull fitting model could accurately describe the temperature rise process of heating module with high reliability, and the temperature rise rate inside the whole heating module presents nonlinearly decreasing trend with the increase of time, as well as the length from the module center. Furthermore, shape and scale parameter dominate the efficiency of the sectional temperature rise and the overall one respectively, and the technical reference is provided for the optimal design of heating module for sodium-sulfur battery and other heating devices. |
