摘要
如何降低电流引线向低温环境的漏热,是超导电力技术领域的一项重要课题。文中概述了电流引线研究进展,建立了电流引线迫流冷却传热模型,并分析了氮气迫流冷却作用,推导了电流引线温度分布和最优长度-横截面积比(ORLA)函数式。自然蒸发迫流冷却对最优长度-横截面积比(ORLA)影响较小。
It is very important to reduce the heat transfer from current lead to cryostat in the field of superconducting technology. In this paper, investigation results were summarized ; heat transfer analysis model was proposed ; force - cooled effect was analyzed, the formula of temperature distribution and optimum ratio of length to area (ORLA) were obtained. The natural evaporation forced - cooling had little effect on the optimum ratio of length to area ( ORLA ).
