Heat Transfer in He II - Dimensional Scaling

对于超导磁体系统，He II是一种理想的冷却剂，因为它具有极大的导热系数和较大的比热。许多大型磁体系统正在使用或考虑使用He II冷却。在所有这些系统中，He II带来了更高的磁场和更高的总热容的优势。He II的另一个大规模应用是在空间低温系统中。空间低温系统利用He II为其等温低温环境，允许以最小的温度梯度有效地冷却部件。这项工作将提供He II的换热系数。

For superconducting magnet systems, He II is a desirable coolant because of its extremely large heat conductivity and large specific heat. A number of large magnet systems are using or considering the use of He II cooling. In all these systems, He II brings the advantage of higher magnetic fields and higher overall heat capacity. The other large-scale application of He II is in space cryogenic systems. Space cryogenic systems utilize He II for its isothermal low temperature environment, allowing efficient component cooling with a minimum of thermal gradients. This work will provide He II heat transfer coefficients.
