A heat shield 10 for the stator of a gas turbine, comprises a plurality of individual segments 10a, 10b with cooling holes 13a, 13b extending between external spaces 14a, 14b and recesses at the end surfaces 15a, 15b, the recesses forming a chamber 11. Cooling fluid is blown through the holes out into the gap 12, and cooling is ensured, even when the gap is closed, by the chamber 11. Height T of the chamber 11 is between 10% and 90% of the thickness D of the heat shield, and its length (L, Fig.2) is between 10% and 80% of the width (B) of the heat shield. |
