Abstract (en)

[origin: WO0171164A1] The invention relates to a blade (13; 14) for a turbine (10) which has at least one channel (22) that can be impinged with a coolant fluid. Several turbulators (23) which improve the heat exchange between the wall (19; 20) and the coolant fluid are provided on at least one wall (19; 20) of the channel (22). In addition, the turbulators (23) reinforce the wall (19; 20) and converge. As a result of said reinforcement, the thickness (d) of the wall (19; 20) in the area between the turbulators (23) can be reduced.
