摘　　要：为解决直接冷却超导磁体中接触界面热阻造成的传热不连续问题,以实验数据为依据采用等效模型模拟接触界面热阻;基于有限元理论分析界面热阻对超导磁体热输运的影响;仿真结果表明等效模型的采用有助于解决低温下超导磁体接触界面间传热的不连续性问题,为研究高温超导磁体的热输运机理提供了一种新思路。The heat transport for the superconducting magnet directly cooled by crycooler is not continuous that is caused by thermal interface resistance （TIR）. To solve this problem, the equivalent model was applied for the simulation on TIR according to present possessed experimental data. In this paper, it mainly studied the effect of TIR on the heat transport for superconducting magnet based on Finite Element Method. The result of simulation suggests that the equivalent model can availably solve the problem of discontinuous heat transport on TIR at low temperature. It provides a new idea for the investigation on heat transport of HTS.
