Abstract
A vacuum insulation element, which consists of a multi-layer configuration of at least two molded plates, that can be subjected to a vacuum, wherein the molded plates in each case have a surrounding edge region which in each case form a sealing surface, wherein the sealing surfaces of the molded plates are hermetically bonded together in the assembled state thus forming a sealing frame, such that a cavity between the, at least two, molded plates is sealed in a manner that is vacuum-tight, and the structure of the, at least two, molded plates distributes the atmospheric pressure which is applied to the multi-layer configuration when subjected to a vacuum such that the specified structure remains stable, wherein the molded plates have numerous molded structural elements in the shape of projections and depressions which face in opposite directions from the molded plates and the projections, or respectively, depressions which face the other plate respectively rest against each other thereby forming a grid of support points when subjected to a vacuum, and the projections, or respectively, depressions which face away from the other plate respectively form numerous cavity cells which can …
