Abstract

PURPOSE:To considerably reduce the amount of external heat infiltrating a cryogenic container, by providing hollow legs for supporting a vacuum vessel so that they are communicated with the vacuum vessel, and supporting the cryogenic container by means of supports which are respectively provided in the hollow legs in such a manner that a spacing is provided between each support and the side walls of the corresponding leg. CONSTITUTION:Legs 6 for supporting a vacuum vessel 4 have a pipe-like configuration. The upper part of each leg 6 is opened inside the vacuum vessel 4, and the lower part thereof is hermetically closed by a pedestal 7, whereby the inside of each leg 6 is kept at a vacuum. A support 8 is provided inside each leg 6 and secured to the associated pedestal 7 so that the support 8 extends upwardly with a spacing provided between the same and the side walls of the leg 6. The upper part of the support 8 is fixed to a seat 9 secured to the side of a cryogenic container 2. Each support 8 is formed so as to have a strength which enables it to endure the weight of the cryogenic container 2 and a load applied thereto when an earthquake occurs. Since the supports 8 extend not only through the vacuum vessel 4 but also through the respective legs 6, the length of the supports 8 can be made, e.g., two or more times as longer as that in the conventional supports. The amount of heat externally entering the cryogenic container 2 by heat conduction of the supports is inversely proportional to the length of the supports. The refore, if the conducting portion of each support 8 has the same material and the same cross- sectional area as those of the conventional support, the amount of heat infiltrating the cryogenic container can be made less than a half as compared with that in the case of the conventional apparatus.
