    Abstract: A method of forming an insulated door panel includes folding side flanges of a metallic sheet to define side edges of a structural outer panel that extend from a front panel. A gap is defined between each set of adjacent side edges. Interior blocks are secured to an interior of the structural outer panel proximate each gap to define adhesive cavities. Exterior blocks are positioned at an exterior surface of the structural outer panel at each gap to further define the adhesive cavities. An adhesive is disposed within each adhesive cavity and is contained therein by the interior and exterior blocks. The adhesive is cured to a solid sealing member that adheres the interior blocks to the interior surface of the structural outer panel to form a sealed structural panel. The exterior blocks are removed and each solid sealing member defines a hermetic seal at each gap.

    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.

    IPC: F25D23/08

    Abstract: An appliance includes an outer wrapper, an inner liner, a trim breaker having a wrapper channel that receives a wrapper edge of the outer wrapper and a liner channel that receives a liner edge of the inner liner, and an insulation material disposed within an insulating cavity defined therebetween. A multi-component thermal encapsulation material defines pre-mix, application and sealing states. The pre-mix state is defined by the distinct components of the thermal encapsulation material being separated from one another, the application state defined by the distinct components combined together into an uncured state of the thermal encapsulation material, and the sealing state defined by the thermal encapsulation material disposed within the wrapper and liner channels and surrounding the wrapper and liner edges, respectively, in the sealing state that defines a hermetic seal between the trim breaker and the outer wrapper and the inner liner.

    Abstract: An appliance includes an outer wrapper, an inner liner, a trim breaker having a channel that receives at least one of a wrapper edge of the outer wrapper and a liner edge of the inner liner, and a composite encapsulation system that hermetically seals an insulating cavity defined between the outer wrapper and the inner liner. The composite encapsulation system includes a base adhesive and an outer adhesive, wherein the base adhesive defines a structural adhesive component and the outer adhesive defines a sealing adhesive component.
