摘　　要：运用FLUNET软件对ITER屏蔽模块上的前集箱进行了数值模拟计算。计算结果表明,前集箱盖板存在冷却不均匀和冷却不够充分的问题。根据数值模拟的结果,对前集箱中的导流板进行了改进,并给出了改进后导流板的几何尺寸和结构。改进后的数值分析结果表明,采用改进后的T型导流板,前集箱盖板的冷却可以满足ITER的要求。The front header of one of the ITER shield blankets is studied using the FLUENT code. The calculation results indicate that the cooling of the front lid in the front header is not adequate and uniform. To meet the design requirement of ITER, the flow driver is improved, and the new structure is given in this paper. According to the analysis, the cooling of the front lid will be adequate and uniform because of the modified flow driver and this can satisfy the design requirement of ITER.
