Heat Transfer in He II - Dimensional Scaling

对于超导磁体系统，He II是理想的冷却剂 由于其具有极大的导热性和大的比表面积， 热 许多大型磁体系统正在使用或考虑使用 使用He II冷却。 在所有这些系统中，He II带来了优势 更高的磁场和更高的整体热容量。 另 He II大规模应用于空间低温系统。 空间 低温系统利用He II的等温低温 环境，允许高效的组件冷却， 温度梯度 这项工作将提供He II传热 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.
