The methods of industrial test and numerical simulation are synchronously utilized to analyze the side heat transfer process in aluminum reduction cell and enhance it in this research. The 3D slice finite element model of aluminum reduction cell is developed, with which the sidewall temperature field of the cell is computed by using software ANSYS. Combining with the results of the industrial test, the main influencing factors of the heat dissipation are analyzed. Some effective measures for enhancing sidewall heat transfer are proposed. The main achievements and conclusions are: The shell temperature of the test cell and the common cell is respectively 312°C and 318°C when the side coefficient of heat transfer between the shell and the surround is 70 W·m-2·K-1. The ledge thickness is 16cm and 15cm. With the increasing of the side coefficient of heat transfer between the shell and the surround, the temperature of the shell decreases but the thickness of the side ledge increases when the electrolytic temperature, the ambient temperature, the coefficient of heat transfer between molten bath and ledge, the eutectic temperature and the thermo-resistance of the side lining are all constant.
