Abstract (en)
[origin: WO2010086381A1] In order to cool a wall (12a), the front side of which is thermally loaded, a cooled component (10) for a gas turbine comprises a plurality of pins (15) that are distributed in a planar arrangement (17) on the rear side of the wall (12a) and project from the wall, and means (14, 16) for producing jets of a cooling medium, said jets being directed to the rear side of the wall (12a) in the region of the pins (15) and being used for impingement cooling. In order to better cool such a component, the pins (15) are more densely distributed in critical zones (Ac) of the component than in the remaining regions.
