The energy balance of aluminum reduction cell is related to its smooth operation, which also has an important impact on the energy saving and consumption reduction. One of key factors determining the energy balance of reduction cells is whether or not the distribution of heat dissipation in each part of the reduction cell is reasonable. Firstly, this paper introduces the division of heat dissipation area in the reduction cell. Then, based on the analysis and excavation of the energy balance test data about 200 reduction cells in some 50 series in recent 20 years, both the distribution characteristics and the change trend of heat dissipation in reduction cells since 2000 are obtained. The analysis results show that there are three stages in the distribution of heat dissipation for reductions cells in the past 20 years. The first stage is the period before 2005~2006, the heat dissipation in reduction cells is generally about 2.0 V; the second stage is 2005~2012, the heat dissipation in reduction cells is generally 1.8~1.9 V; and the third stage is the 2017~2019, the heat dissipation in reduction cells is generally 1.6~1.7 V. The change of heat dissipation distribution reflects the development course and trend of energy saving technology in aluminum electrolysis, which exhibits the strategies and concept of energy balance control in aluminum reduction cells. This study will provide theoretical support and data reference for energy balance control, energy saving and consumption reduction in aluminum reduction cells in the future.
