Each side component (2), at least in the region of the connecting elements (4-11), has an essentially L-shaped profile. The side surfaces (2b) flank a region of the broad side of the water boxes (1) and the face surfaces (2a) flank the narrow side of the water boxes. A pair of joining elements (4,5,6,7;8,9,10,11) is provided for the side surface and the face surface. The joints are made using gaps (7,9,11) and matching projections (4,5,8,10). |
