摘    要：将铝电解槽壳底部及侧部分解成三种散热单元，这三种散热单元可排列与组合成各种现代铝电解槽壳表面结构。提出了开口向下水平平板肋的稳态自然对流与表面辐射的耦合传热新模型，并结合另外两种单元的耦合传热模型对肋板的温度分布、散热量等进行计算求解，对肋板性能进行分析。用三种检验方法检验三种散热模型，设计编写的数值计算程序和近似计算程序能简单、精确、快速地计算不同类型的电解槽壳的散热，计算结果较原有行业算法包含更多的信息量。

Abstract: The heat transfer was analysed numerically by the conduction, natural convection and radiation on the aluminium reduction cell shells. The temperature, the heat dissipation and other data of the fins were calculated, and the characteristics of which were analysed and tested by in-situ measurement. The numerical programs have been designed, by which the calculated results of the heat dissipation of different kinds of aluminium reduction shells can be obtained easily and quickly. Besides, the programs provide more information than any other existing algorithms.
