The heat exchanging element is rectangularly delimited. Such elements can be laid together as floor or wall coverings, and can be used as primary or secondary heat exchanging elements. Fig. 1 shows a top view, and Fig. 2 a section through the plane A-A. The hollow plate consists e.g. of concrete. The feed socket and the removal socket 8 and 9, respectively, are inserted into the side wall 3 - near the corner of the hollow plate, in each case. At both of its corners, the side wall 5 opposite the side wall 3 has recesses 11 and 12, each of which, when the hollow plates are laid together in rows, in conjunction with the neighbouring recess offers the adjacent hollow plate room to accommodate adjacent sockets including a U-shaped connection between them. The recesses 11 and 12 are overlapped by the cover wall 2. The first step in laying a surface with this component is to form a row in such a way that the side walls 3 remain free. Adjacent sockets of neighbouring plates can then conveniently be connected to one another in a U-shaped fashion. When the next row is inserted, its cover walls 2 overlap the recesses 11, 12 of the previously inserted row. <IMAGE> |
