Abstract
The invention features a refrigerator cabinet door frame. The frame includes a thermally conductive outer frame, a thermally insulating inner frame member, and a sealing plate. The outer frame member includes a forward end having an outer surface that is disposed outside of a refrigerated cabinet with the frame mounted, and a rearward end defining a joint. The inner frame member includes a first end retained in the joint, and a second end. The sealing plate includes a first edge coupled to the outer frame member at the rearward end, forward of the joint, a second edge supported by the second end of the inner frame member, and a thermally conductive sealing surface. The first edge of the sealing plate is coupled to the outer frame member such that the sealing surface and the outer surface of the outer frame member together form a continuous heat transfer path.
