  • Vacuum insulation system for insulating refrigeration cabinets
    Patent number: 5082335
    Abstract: A refrigeration appliance having a vacuum insulation system wherein a combination of vacuum thermal insulating panels and polyurethane foam provide the thermal insulating properties as well as structural support. The panels are to be spaced apart from one another with a space between the cabinet and appliance liner so that the foam will lock the panels in place. Also the panels are to be spaced from the corners of the cabinet to permit the foam to flow into the corners. The panels can be applied directly to the cabinet or they can be spaced between the cabinet and liner, held by spacers. In either case, an adhesive is used to hold the liners in position prior to introduction of the foam.
