The assembly edge is formed by an edge-sided deformation of a steel sheet plate. The edge cooperates with a frame that is made of metal, wood and/or plastic. A self-cutting screw provides connection between the edge and the frame. The device includes a pipeline (9) via which heating- and/or cooling medium flows, and a plate-shaped heat conducting element (6) that is made of expanded graphite.</p> |
