Including Thermal Insulation Patents (Class 220/592.09)
  • Patent number: 7007747
    Abstract: Structural support apparatus with active or passive heat transfer system with a flexible insulated container, a rigid heat-conductive metallic element, a heat exchange system, where the metallic element structurally supports the container. The metallic element and container form a waterproof bond, and the metallic element and heat exchange system form a thermal bond. A preferred embodiment includes a flexible insulated container forming a closed volume with a plurality of flexible walls.

  • Patent number: 6637615
    Abstract: A thermal insulation box has upper protrusions and front protrusions formed on the top face and on the front faces of an ice bin, respectively. A step is formed on the upper face of a front panel. The front panel, which has on the rear face holding recesses for admitting the front protrusions formed in the ice bin, is fitted to cover the front protrusions with the holding recesses. A top plate has a reinforcing rib formed integrally therewith circumferentially along the lower edge. With the top plate being attached to the casing body, the front part of the reinforcing rib is fitted to cover the step of the front panel, whereas the side parts of the reinforcing rib are fitted to cover the upper protrusions of the ice bin.

  • Publication number: 20030167789
    Abstract: By using a core made of laminated sheets of inorganic fibers having a particular shape and composition as part of a vacuum heat insulator for a heat insulation box, a heat insulation box excellent in long-term heat insulating properties and productivity can be provided. The vacuum heat insulator can be shaped easily. Therefore, a vacuum heat insulator suitable for a required heat insulation portion can be produced easily and applied to a heat insulation box. This property can increase coverage of the vacuum heat insulator on the heat insulation box, thus improving heat insulating properties of the heat insulation box. This can improve heat insulating properties and productivity of a refrigerator, thermal storage box, cold storage box, or vending machine, and contribute to energy savings.

  • Patent number: 6474498
    Abstract: Containers for liquids, commonly dispensed for consumption at a temperature below ambient (such as chilled soft drinks cans) can be maintained for extended periods below ambient, after they have been dispensed from a refrigerated container, by providing a lining member formed from a plastics material having closed cells and providing insulating properties. The lining member may, for instance, have large cells and be dimensioned to fit within the shell of the container, or can be formed as a layer on the internal surface of the shell of the container.

  • Patent number: 6408841
    Abstract: A heat insulated wall having two surface layers disposed at a distance from one another and are at least substantially vacuum-tight in construction. The two surface layers together with an at least substantially vacuum-tight connection element enclose an evacuable space that is filled with an evacuable thermal insulation material. The surface layers have angled sections with free ends directed away from the space and on which the connection element is disposed and is fastened in a vacuum-tight fashion to the angled sections.

  • Patent number: 6305768
    Abstract: A heat insulation box body includes inner and outer boxes forming a shell of the heat insulation box body and triangular structural materials inserted in the shell held by close-contact by means of a vacuum. Further, at the time of disassembling the heat insulation box body after scrapping, a shell surface is cut and air is introduced into the inside of the shell to return the state of the shell to an atmospheric pressure state and then respective members are separated from each other.

  • Patent number: 6244458
    Abstract: A container has a base, peripheral walls and a lid. Each of the base, peripheral walls and lid includes an interior wall spaced from an exterior wall, with vacuum panel in between. The sides of the vacuum panels are covered by compressible insulation fill, minimizing thermal flow along the vacuum panels despite any manufacturing tolerance differences in the width of the vacuum panels as compared to the distance between the interior wall and the exterior wall. The interior wall of the body of the container is provided by a liner formed of a single, deep drawn sheet of material. The exterior wall is similarly formed as a deep drawn shell. The inner liner and the outer shell are welded together with a bead to encase the vacuum panels in a water-tight manner, with the liner, the shell the bead all formed of the same material.

  • Patent number: 6224179
    Abstract: A heat-insulating housing, such as for an oven chamber of a household oven or a refrigeration chamber of a household refrigerating appliance, includes at least one working space which is surrounded by housing walls and can be closed by a door. The housing walls are formed from two substantially dimensionally rigid housing shells which are at a spacing from each other and together substantially enclose an intermediate space that can be evacuated and is filled with heat-insulating material which can be introduced loosely.
