Abstract
In a cooled wall part having a plurality of separate convectively cooled longitudinally cooling ducts (2) running near the inner wall (1) and parallel thereto, adjacent longitudinal cooling ducts (2) being connected to one another in each case via intermediate ribs (3), there is provided at the downstream end of the longitudinal cooling ducts (2) a deflecting device (4) which is connected to at least one backflow cooling duct (6) which is arranged near the outer wall (5) in the wall part and from which a plurality of tubelets (7) extending to the inner wall (1) of the cooled wall part and arranged in the intermediate ribs (3) branch off. By means of this wall part, the cooling medium can be put to multiple use for cooling (convective, effusion, film cooling).
