摘要： A folded core structure formed from an uncut flat body, has a plurality of consecutive 3D-structures and connecting areas each formed by plastic deformation, and includes first and second primary surfaces oriented plane-parallel to each other. The first and second primary surfaces include a first secondary surface extending over the entire width of the folded core structure and extending over a part of the length of the folded core structure. The first secondary surface is oriented parallel to the first primary surface, and the first secondary surface is located at a distance from the first primary surface between the first and second primary surfaces. A channel for fluid flow at least along the width of the folded core structure is provided. The first and/or second primary surface is/are configured to provide dimensional stability under a compression force applied perpendicular to the first primary surface of the folded core structure.
