Abstract
A vacuum insulated structure and method of forming are provided. The vacuum insulated structure includes an inner liner and an outer wrapper coupled to the inner liner and defining an insulating cavity. A plurality of insulation packages are disposed within the insulating cavity. Each insulation package includes a first filler material contained within an envelope. A second filler material is disposed within the insulating cavity.
Claims20
A vacuum insulated structure, comprising:
- an inner liner;
- an outer wrapper coupled to the inner liner and defining an insulating cavity;
- a plurality of insulation packages disposed within the insulating cavity, wherein each insulation package comprises a first filler material contained within an envelope, and wherein the plurality of insulation packages are arranged to define a plurality of adjacent offset columns;
- and
- a second filler material disposed within the insulating cavity, wherein the second filler material is positioned between adjacent ones of the plurality of insulation packages such that the second filler material extends between each of the adjacent ones of the plurality of insulation packages, and wherein each of the plurality of insulation packages extends from the inner liner toward the outer wrapper.
