摘    要:针对超导磁储能系统(SMES)磁体直接冷却G-M制冷机冷头与磁体之传导路径较长造成超导磁体轴向温差的问题,提出了采用低温热管进行均温的方案,以对流换热系数为目标函数建立了相应的热管冷凝数学模型,较之于传统的模型所建模型考虑了二相流界面间的摩擦切应力,所建模型适用于SMES冷却系统降温和失超阶段传递热流量较大工况的传热分析.

关 键 词:超导磁储能  直接冷却  低温热管  建模  传热分析

Abstract:Aiming at reducing the axes-orientation temperature difference of superconducting magnet,which mainly results from a long conducting path between cooling head of G-M refrigerator and magnet in Superconducting Magnet Energy Storage(SMES) system,a novel method of applying cryoheat pipe is described.A heat pipe condensing model is established that focuses on the coefficient of convection heat transfer and consideration of the tangent friction stress between interfaces of two phase flow.This model is superior to a traditional one in analyzing the massive heat transfer in periods of lowering the temperature and quench.
Keywords:Supercouducting Magnet Energy Storage(SMES)  directly cooling  cryo-heat pipe  modeling  thermal analysis
