摘　　要：本文分别对并联和串联氦气(GHe)冷却方式下,百米级CORC(Conductor-on-Round-Core)CICC(Cable-in-Conduit-Conductor)导体的轴向温度分布进行研究。基于三维仿真模型,分析了不同质量流量下,氦气冷却流的热特性对CORC CICC轴向温度分布的影响。并联冷却布置的CORC CICC入口和出口之间的氦气轴向温差小于3 K;当dm/dt=5 g/s时,串联冷却布置的CORC CICC的CORC铜管出口处氦气的温度更接近于中心管道入口氦气的温度。In this paper,the axial temperature distribution of 100 m-class CORC CICC cooled by GHe with parallel-flow and counter-flow arrangements were investigated,respectively.Based on a three-dimensional simulation model,the influence of the thermal characteristics of CHe cooling streams with different mass flow rates on the longitudinal temperature distribution of the CORC CICC was analyzed.The axial temperature difference of GHe between the inlet and outlet of the CORC CICC with parallel-flow arrangement was less than 3 K.The temperature of GHe at the outlet of the CORC copper tubes of the CORC CICC with counter-flow arrangement is closer to the temperature of GHe at the inlet of the center pipe when dm/dt=5 g/s.
