基于精力保存的原则，为从常规的翻新的排干的房间的适用的技术与 2D 被分析有限元素模型。模型采用了一个标志热转移计划反复地计算 freeze 侧面直到厚度变量到达了终止要求。从房间表面的计算 2D 热驱散被变换成全面 3D 热损失。系统的潜在的落下，冻结侧面，当设计 150 kA 时，热平衡被分析与技术参数评估他们的变化常规房间基于的排干的房间。翻新的排干的房间能保持热的模拟结果表演在水流是 190 kA 的条件下面平衡，阳极电流密度是 0.96 A/cm~2 ，阳极阴极距离是 2.5 厘米，氧化铝盖子与 0.20 的热传导性是 16 厘米厚的有( m ·℃)和电解温度是 946 ℃。
英文摘要：
Based on the principle of energy conservation, the applicable technique for drained cell retrofitted from conventional one was analyzed with 2D finite element model. The model employed a 1D heat transfer scheme to compute iteratively the freeze profile until the thickness variable reached the terminating requirement. The calculated 2D heat dissipation from the cell surfaces was converted into the overall 3D heat loss. The potential drop of the system, freeze profile and heat balance were analyzed to evaluate their variation with technical parameters when designing the 150 kA conventional cell based drained cell. The simulation results show that the retrofitted drained cell is able to keep thermal balance under the conditions that the current is 190 kA, the anodic current density is 0.96 A/cm^2, the anode-cathode distance is 2.5 cm, the alumina cover is 16 cm thick with a thermal conductivity of 0.20 W/（m℃） and the electrolysis temperature is 946 ℃.
