Abstract
Plaques are formed on the sidewalls of the liner in a refrigerator to reduce thermally induced bowing of the cabinet. The plaques may consist of indentations in the liner, which in a preferred form are rectangular, or arrays of multiplanar indentations. The plaques provide increased surface area in the liner to permit thermal expansion without bowing, and also increase the structural rigidity of the liner to resist bowing. Thermal bowing is encountered where there are long unsupported wall surfaces and high temperature gradients across the wall. Therefore the plaques are very effective in the freezer compartment of a side-by-side refrigerator, where bowing can be severe in the absence of the disclosed corrective measure.
