本文根据传热学Fourier定律,建立了用铝骨架间接冷却的超导磁体在能量脉冲的作用下的瞬态传热模型。在超导体内部各向同性的假设前提下将其简化为一维瞬态导热问题,并求出了它的分析解。在此基础上,运用计算机对这种间接冷却的超导磁体进行了模拟实验,得出了在不同电流密度,不同能量脉冲、不同线圈厚度以及不同冷却条件下的正常区收敛速度的四组曲线,并对计算结果进行了解释。 In this paper, according to Fourier’s law of heat transfer, a transient heat transfer model of superconducting magnet cooled indirectly by aluminum skeleton under energy pulse is established. Under the assumption of the isotropic internal structure of the superconductor, it is reduced to one-dimensional transient thermal conductivity problem, and its analytical solution is obtained. On the basis of this, a computer is used to simulate the indirectly cooled superconducting magnet, and the four curves of the normal zone convergence rate under different current densities, different energy impulses, different coil thicknesses and different cooling conditions are obtained , And explained the calculation results.
