  • Patent number: 11247752
    Abstract: A double-shell tank includes: an inner shell storing liquefied gas; an outer shell surrounding the inner shell, the outer shell forming a vacuum space between the inner shell and the outer shell; at least one metal sheet mounted to the inner shell, such that the metal sheet faces at least a bottom surface of the inner shell; an adsorbent placed on the metal sheet, the adsorbent adsorbing gas molecules by physisorption; and a thermal insulator covering the inner shell over the metal sheet.
    Type: Grant
    Filed: October 9, 2018
    Date of Patent: February 15, 2022
    Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHA
    Inventors: Hiroki Nakado, Masashi Shingo, Kazuto Gokan, Ryosuke Uraguchi
  • Patent number: 10947038
    Abstract: A thermal insulating structure includes: at least two retainers that protrude from a to-be-insulated surface exposed to a vacuum space; at least two first multilayer vacuum insulating sheets adjacent to each other with the retainers positioned therebetween, the insulating sheets covering the to-be-insulated surface; at least one second multilayer vacuum insulating sheet that extends between the retainers along a boundary between the first multilayer vacuum insulating sheets in a manner to cover the boundary; at least two third multilayer vacuum insulating sheets that are adjacent to each other with the retainers positioned therebetween, the at least two third multilayer vacuum insulating sheets covering the first multilayer vacuum insulating sheets and the second multilayer vacuum insulating sheet; and a keep plate that is fixed to the retainers and holds the first multilayer vacuum insulating sheets, the second multilayer vacuum insulating sheet, and the third multilayer vacuum insulating sheets.
