阿贡国家实验室正在研究一种热虹吸冷却系统，作为超导波动磁体开发的一部分。威斯康星大学麦迪逊分校进行的分析解决了充氦冷却回路的几个独特特征，包括与流体静压头相关的过冷，主要沿水平通道沉积的热负荷的影响，以及在极低质量条件下的两相流特性。分析结果与全尺寸冷却回路的实验测量结果进行了比较。通过探索氦冷却回路的单相和两相区域的流动诱导传热，分析和测量都解决了保持超导绕组远低于其电流共享温度的设计目标。
A thermosiphon cooling system is being pursued as part of the superconducting undulator magnet development at Argonne National Laboratory. Analyses carried out at the University of Wisconsin-Madison address several unique features for the helium-filled cooling loop including sub-cooling associated with the hydrostatic head, the impact of a heat load deposited primarily along the horizontal channel, and two-phase flow characterization at extremely low quality conditions. Results of the analyses are compared with experimental measurements for a full-scale cooling loop. Both the analyses and measurements address the design objective of maintaining the superconducting windings well below their current sharing temperature by exploring the flow induced heat transfer to the single and two-phase regions of the helium cooling loop.
