Abstract (en)
[origin: EP1219780A2] A cooling device for a turbine blade (1), of which the leading edge (3) has to be cooled, is in the form of a cooling channel (4) extending radially towards the blade. In the leading edge region, the channel is bounded by a separating wall (8), which, with the blade wall, encloses a space (6) in the region of the leading edge.
