摘　　要：提出将室温液态金属作为高载流电缆的导电及冷却介质,通过电流、温度及流动等三维多物理场耦合数值仿真方法研究了不同工况下液态金属冷却高载流电缆的温度变化规律,并与电缆传统水冷进行了详细对比,结果表明,液态金属具有高效的冷却效果。同时,搭建了液态金属冷却电缆实验平台,初步验证了液态金属冷却高载流电缆的可行性。This paper proposed a novel cooling method for cable with large current based on room temperature liquid metal. The three.dimensional simulation method for thermal fluid coupled with electric field was developed to study the cooling performance of liquid metal, which is also used to be compared with the traditional water.cooled cable. The experimental platform of liquid metal cooling cable is built to verify the cooling reliability and safety of the liquid metal cooling cable, providing structural scheme for the high.current liquid metal cooling cable.
