Adjacent longitudinal cooling channels (2) are joined to one another via intermediate ribs (3). At the downstream end of the channels a deflector device is provided, which is connected with a back flow cooling channel (6) near to the outer wall in the wall part. From the deflector device a number of small tubes (7) branch off and are arranged in the intermediate ribs. The small tubes run to the inner wall (1) of the cooled wall part, and are arranged at right-angles to the flow direction in the back flow cooling channel. Alternatively, they can be arranged at an acute angle. The wall part is a combustion chamber cooling tile and the inner wall of the cooled wall part is flown around from the combustion chamber flow.
