MULTI-SECTION CORE VACUUM INSULATION PANELS WITH HYBRID BARRIER FILM ENVELOPE

摘要

A multi-layer vacuum insulating panel that includes: a first barrier film having at least one polymeric material layer and; a second barrier film having at least one interior polymeric layer, a metal foil layer, and at least one exterior polymeric layer positioned on the opposite side of the metal foil layer as the at least one interior polymeric layer; a sealing junction between the first barrier film and the second barrier film at a sealing section about a perimeter of the first barrier film and the second barrier film where the first barrier film and the second barrier film physically and sealingly engage one another; and a multi-section central core having a first fumed silica region that contains at least one fumed silica compound and at least one fibrous (fiberglass) region that are each discrete regions within the interior volume.

1. A multi-layer vacuum insulating panel comprising:
a first barrier film comprising at least one polymeric material layer wherein the first barrier film is free of a metal layer and wherein the first barrier film has an interior facing surface; a second barrier film comprising at least one interior polymeric layer, a metal foil layer, and at least one exterior polymeric layer positioned on the opposite side of the metal foil layer as the at least one interior polymeric layer; wherein the and the first polymeric barrier film define an interior volume between the first barrier film and the second barrier film and wherein the interior volume has a width, a length and a height; a sealing junction between the first barrier film and the second barrier film at a sealing section about a perimeter of the first barrier film and the second barrier film where the first barrier film and the second barrier film physically and sealingly engage one another; and a multi-section central core having a first fumed silica region that comprises at least one fumed silica compound and at least one fiberglass region that are each discrete regions within the interior volume; and wherein the first fumed silica region is positioned within the interior volume and further positioned either (a) along at least a majority of a portion of the interior facing surface of the first barrier film or (b) along and proximate the sealing section and bridging the sealing junction where the first barrier film and the second barrier film engage one another; and wherein the portion of the interior volume free of the first fumed silica region defines a remaining interior volume; and wherein the at least one fiberglass region is positioned within the remaining interior volume.
