The flat tubes, with corrugation peaks, corrugation valleys, and corrugation flanks connecting them, have a multiple recess (4, 44) in their broad sides (3), in which some of the ribs engage. The peaks of the ribs fit in the recesses (44) of one flat tube, and their valleys (21) of the adjacent flat tube.</p> |
