摘　　要：针对制冷机直接冷却高温超导磁体电流引线的传热特性进行理论分析,对其在不同结构模式下进行漏热计算和比较,找到了大通流(kA级)电流引线结构优化设计方法和电流引线漏热与通电电流的关系式。The theoretical analysis of heat transfer performance of current lead on cryocooler-cooled High Temperature Superconducting(HTS) magnet is presented.Through the heat leak calculation and result comparison under the different modes of current lead excited by the large electric current,the method of the optimum design of lead structure is found.Finally,the relational expression between heat leak of current lead and electric current is obtained.
