摘　　要：终端盒是聚变堆结构冷却馈线系统中的关键部件,为其内部的冷却管等冷质部件提供真空环境。阐述了方形终端盒和圆筒形终端盒的结构特点,针对壁厚40 mm的方形终端盒及壁厚25 mm的圆筒形终端盒在容积相同的情况下进行了强度分析和稳定性分析,结果表明圆筒形终端盒具有较高的强度并且所需的304L不锈钢显著少于方形终端盒。Terminal box is the key component in the structure cooling feeder system for fusion reactor, which is used to provide vacuum environment for cryopipes and other cold mass＇inside terminal box. In this paper, the structural characteristics of cuboid and cylindrical terminal boxes are presented, then the strength analysis and stability analysis of cuboid terminal box with wall thickness of 40 mm and cylindrical terminal box with wall thickness of 25 mm under the same volume are performed. The results indicate the mechanical strength of cylindrical terminal box is much higher than cuboid terminal box. Additionally, the 304L stainless steel used to develop the cylindrical terminal box is remarkably less than cuboid terminal box.
