摘　　要：提出了深孔钻直冷方案用于优化ITER极向场PF6磁体支撑冷却系统设计。采用有限元分析方法,从换热效率、流体压降、结构强度等方面对流道数量和孔径进行了最优化设计。结果表明,9条直径10mm的冷却流道可以达到最佳的冷却效果。同时,在服役环境下支撑部件的机械强度和温度分布、流体的运行参数均能满足ITER磁体支撑的设计要求。目前所有PF6磁体支撑已完成了制造和检验,并顺利交付ITER组织。A deep hole drilling direct cooling scheme is proposed to optimize the design of the ITER poloidal field PF6 magnet support cooling system. The finite element analysis method is used to optimize the number and diameter of flow channels in terms of heat transfer efficiency, fluid pressure drop, and structural strength. The results show that 9 cooling channels with 10 mm diameter can achieve best cooling effect. At the same time, the mechanical strength and temperature distribution of the supporting components, and the operating states of the fluid under service environments can meet the design requirements of the ITER magnet support. At present, all PF6 magnet supports have been manufactured and inspected, and successfully delivered to the ITER organization.
