Zusammenfassung:A stator heat shield (1) for a gas turbine is provided, the gas turbine comprising a hot gas flow path, the stator heat shield (1) comprising a first surface (2) adapted to be arranged to face the hot gas flow path of the gas turbine; a second surface (3) opposite to the first surface (2); cooling channels (5) for directing cooling fluid (4) from the second surface (3) towards the first surface (2); cavities (6) arranged at the first surface (2) for receiving the cooling fluid (4) from at least a part of the cooling channels (5); wherein at least a part of the cavities (6) each have at least two corresponding cooling channels (5) open thereto, said at least two corresponding cooling channels (5) being inclined towards each other. In use, a vortex is created in the cavity (6).
