【摘要】：以GT Solar公司DSS~(TM)450型多晶硅铸锭炉为例,建立了铸锭炉热场的三维热学模型,由此计算并获得了炉内的三维热场分布,发现热场呈三维分布,而不是简单的二维轴对称分布;比较了4种不同功率分配方案的热场分布,发现提高顶部加热器的功率配比对温度不均匀性有一定的改善,但却会使加热效率大大下降;对冷却板内的温度分布也进行了数值模拟,发现支撑柱对热场有重要影响。
[Abstract]:Taking the DSS~ (TM) 450 polycrystalline silicon ingot furnace of GT Solar Company as an example, a three-dimensional thermal model of the ingot furnace is established. From this model, the three-dimensional thermal field distribution in the furnace is calculated and obtained. It is found that the thermal field is a three-dimensional distribution. Instead of a simple two-dimensional axisymmetric distribution; The thermal field distribution of four different power distribution schemes is compared. It is found that increasing the power ratio of the top heater can improve the temperature inhomogeneity to some extent, but it will greatly decrease the heating efficiency. The temperature distribution in the cooling plate is also numerically simulated, and it is found that the supporting column has an important effect on the thermal field.
