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.
