摘要 为了满足ITER国际组对CTB盒体冷屏的技术要求,论文对其结构型式和传热性能分别进行了设计、选型和数值模拟分析。通过对设计后的冷屏结构进行ANSYS分析,选择了冷屏为3mm厚的3003铝合金材料,确定了冷却管为22mm×22mm-φ18mm外方内圆截面的结构型式,并选择由卡子实现冷却管与冷屏面板的连接固定。最后,利用FLUENT软件针对设计后的冷屏结构进行了流固耦合数值模拟分析,获取了冷屏面板上总体温度的分布情况,验证了论文中选取和设计的冷屏结构型式能够满足ITER国际组设计技术要求,为下一步CTB盒的设计研制提供了技术保证和依据。 Based on the performance request of CTB thermal shield in ITER DDD 11 Magnet,the structure of CTB thermal shield has been designed and numerically simulated for feeder of ITER.In this paper firstly the 3003 aluminum material with 3mm thickness is selected as panel and the square-to-circle section with 22mm×22mm-18mm as cry-pipe and the clamp as connection for panel with cry-pipe.Then the CTB thermal shield is simulated and analyzed on the coupling between fluid and solid by software FLUENT,and the temperature distribution on all panels has been obtained,which is useful to improve the finally design and mass production of CTB thermal shield.
