Abstract: A refrigerator includes a wrapper having an opening with a front edge. A liner includes an opening and a front edge. A thermal bridge interconnects the wrapper and the liner to form a vacuum insulated cavity therebetween. The thermal bridge includes an outwardly opening channel and first and second inwardly opening channels. The front edge of wrapper is received in the first inwardly opening channel, and the front edge of the liner is received in the second inwardly opening channel. The second inwardly opening channel is inset relative to the first inwardly opening channel on the thermal bridge. A conduit is disposed within the outwardly opening channel and is configured to circulate a heated medium. The wrapper and liner are contemplated to be comprised of conductive materials, such sheet metal, while the thermal bridge is comprised of a thermally resistant material, such as a polymeric material.

Abstract: A vacuum insulated structure includes a first panel and a second panel, wherein the second panel is operably coupled to the first panel to define an insulating space therebetween. An airway system is disposed within the insulating space and includes portions of porous tubing configured to draw air along lengths of the porous tubing from the insulating space during an evacuation procedure. A plurality of connectors interconnect the portions of porous tubing of the airway system to inner walls of the insulating space. The connectors may include support members that extend between the panels within the insulating space to support the vacuum insulated structure under vacuum pressure. Further, first and second panels can include rigidifying structural configurations to combat vacuum bowing during the evacuation procedure.

Abstract: A vacuum insulated refrigerator structure includes a shell having a liner and a wrapper where the shell defines an internal vacuum cavity, and a refrigerator and/or freezer compartment. The vacuum insulated refrigerator structure additionally includes an elongated pass-through defining an elongated internal space having a central portion disposed in the internal vacuum cavity. The elongated pass-through has opposite end portions that are sealingly connected to the shell, each opposite end portion having an opening that permits access to the elongated internal space from the outside of the shell. The vacuum insulated refrigerator structure also includes a vacuum core material fill positioned in the internal vacuum cavity and one or more utility lines disposed in one or more elongated internal passageways extending out of the openings at the opposite end portions of the elongated pass-through.
