特許文献2は、軸を中心として回転する回転子を有する機械を開示しており、その回転子の超電導巻線が、固定配置されて回転子空所内に突出する熱伝導体の中央冷媒空間に、巻線支持体および熱接触ガスを介して熱伝導結合されている。その冷媒空間は、それの側方に配置された管部材および機械の外側にある冷凍ユニットの凝縮器空間と共に、冷媒が熱サイホン効果に基づいて循環する管システムを構成している。回転子の斜め傾いた姿勢においても中央冷媒空間への冷媒供給を維持するために、冷媒空間には高い熱伝導性の多孔性材料、とりわけ焼結材料からなる内張が設けられている。
蒸発器は、一般に空洞として構成されており、その空洞の境界を蒸発器表面として使用することができる。従って、液体冷媒の充填率に応じて、より大きな又はより小さな蒸発器表面を液体冷媒の蒸発のために使用することができる。液体冷媒に接することのできる表面を、液体冷媒量を増す必要性なしに拡大するために、液体冷媒に接することのできる蒸発器表面を拡大するための手段が、液体冷媒を押しのけるための少なくとも1つの押しのけ部材を有することが提案されている。それにより液体冷媒に接することのできる蒸発器表面の拡大と同時に冷媒が節約される。
