摘要
提出了一种较为精确计算电流引线长横比及由电流引线末端流入低温容器热量的计算方法。在确定了电流引线的长横比之后,一个重要的问题是确定电流引线的截面积,从而进一步由长横比确定电流引线的长度。从传热学中的特征式关联式出发,给出一种电流引线冷却面积的计算方法,并以黄铜为例计算了电流引线的结构尺寸。
A kind of method is given up that calculate precisely the current lead's shape factor and the heat loads which fluid into the cryostat. After the shape factor of the current lead is determined, an important task is to ascertain the section area, and then, with the shape factor to determine the length of current lead. The section area can be worked out according to relational formula of characteristic formula in the heat transfer. As an example, the structural dimension of the current lead made of brass is calculated in the last.
