摘要：纯金属在低温下具有极大的导热系数，因此是低温器件中传导冷却的关键材料。铝就是这种材料的一个典型例子，到最近为止，它可以高度提纯并以商业数量提供。本文首先介绍了6N纯铝的导热性能，然后简要回顾了纯金属的导热理论。结果表明，6N纯铝细丝在6K时的导热系数达到4万W/(MK)。这项研究还描述了通过纯铝制成的热链进行的振动传递，这是精确测量的关键问题，例如使用低温干涉引力波望远镜的测量。结果表明，在导热系数的尺寸效应不占优势的情况下，采用细导线制成的多股绞合电缆是有效的。
Synopsis: Pure metals have extremely large thermal conductivity at cryogenic temperatures, and are therefore key materials for conduction cooling in cryogenic devices. Aluminum is a typical example of such a material, and as of recently, it can be highly purified and provided in commercial amounts. In this paper, the heat-transfer performance of 6N pure aluminum is reported, followed by a brief review of conduction theory on pure metals. It was confirmed that thermal conductivity of 6N pure aluminum fine wires reached 40, 000W/(m K) at 6K. This study also describes vibration transfer through a heat link made of pure aluminum, which is a critical issue for precise measurements, such as those using the cryogenic interferometric gravitational wave telescope. It is shown that use of stranded cable made of thin wires is effective for this purpose when the size effect of thermal conductivity does not dominate.
