摘要
用有限时间热力学最小熵产率的方法对连续冷却电流引线进行优化 ,比较高温超导电流引线连续冷却和冷端冷却两种直接冷却方式。优化后的连续冷却电流引线上热流量随温度的降低而减小 ,温度在高温段变化较快 ,熵产率小。冷端冷却时在整个引线上热流量分布相同 ,温度在低温端变化较明显 ,熵产率较大。优化后的连续冷却方式比冷端冷却方式合理。
The continuous cooling HTS current leads were optimized by the method of entropy generation minimization of finite-time thermodynamic. The continuous conduction cooling method was compared to the low temperature end conduction cooling method. Heat flux decreases with temperature along the optimized continuous conduction cooling HTS current leads, and the temperature changes evidently in the high temperature part of HTS current leads. Heat flux maintains constant along the low temperature end conduction cooling HTS current leads. From the point of view of entropy generation, the optimized continuous conduction cooling method is superior to the low temperature end conduction cooling method.
