摘　　要：ITER超导纵场线圈内馈线系统位于主机杜瓦内,由18个盒体分别悬挂于相应纵场磁体终端,通过连接件组成多边形环。通过对内馈线在整个装置降温收缩过程的分析,采用有限元分析法对内馈线稳态及瞬态温度场进行数值模拟,得到内馈线的热负荷值、温度分布、温度及变形的时间历程曲线,为内馈线冷却方案的确定和降温时间的预测等提供了可靠验证。The ITER TF In - cryostat feeder system（ICF） locates in the main cryostat of the Tokamak. It consists of 18 segments which form a ring by connectors and hanging on the responsible TF coil terminal area. Researching on cooling process of the ITER TF ICF system, Finite Element Method （FEM） is applied on the numerical simulation of the steady-state and transient temperature field in the ICF. The heat load and temperature distribution in ICF is worked out; furthermore, the temperature -time curve and deformation -time curve are also presented. That will validate the cooling scheme and forecast for the time to cooling down the ICF.
