The optimization study of the cooling structure has been done in order to establish the design manual of the next generation superconducting magnets. The cryogenic Oscillating Heat Pipes(OHP) have been developed, which is used by being imbedded in the magnet windings as a heat transfer enhancement device. It has been demonstrated for the first time in the world, and the high heat transport properties of the cryogenic OHP have been experimentally confirmed. The obtained data sets have been used to make a fitting by means of multi-regression analysis. The modeling with non-dimensional quantities is useful for the design of cryogenic OHP and the optimization of the cooling structure of the superconducting magnets.

为制定下一代超导磁体的设计手册，对冷却结构进行了优化研究。研制了一种嵌入磁体绕组中的低温振荡热管（OHP）。这在国际上尚属首次，并从实验上证实了低温OHP的高传热性能。所得数据集已被用来进行拟合，通过多元回归分析。该模型的无量纲化对超导磁体冷却结构的优化和低温OHP的设计具有重要意义。
