Optimal design of HTS current lead considering natural convection
자연대류를 고려한 초전도 전류도입선의 최적 설계
Abstract
In this paper the HTS current lead for superconducting device is studied numerical method. The current lead is cooled by surrounded He gas by natural convection. To find wall heat flux, the linearization method is adopted Numerical results using natural convection cooling are compared with conventional cooling methods such as conduction cooling and vapor cooling. The results shows that the minimum heat dissipation is much smaller than conduction cooling. Also, the minimum heat dissipation is obtained for the non-zero gradient of temperature at warm end. HTS current lead operating current sharing mode is reduce heat flow to superconducting system.
