Claims
- 1. A heat shield, comprising:a plurality of individual segments, said segments include end surfaces which respectively are aligned and spaced apart with respect to one another so as to form a gap, said segments each further including opposite side surfaces, with a first one of said opposite side surfaces being in contact with a cooling fluid, and a second one of said opposite side surfaces being in contact with a hot gas flow, and cooling holes being defined within each of said segments extending from said first side surface to the end surfaces and through which cooling holes a cooling fluid is blown out into the gap, said cooling holes opening into a chamber which is wider than the gap and is arranged in the region of the gap, wherein the chamber is configured as a recess which extends into the gap starting from the second side surface of each of said segments, said second side surfaces forming the thermally loaded side of the heat shield.
- 2. The heat shield as claimed in claim 1, wherein the chamber has a depth and the heat shield has a thickness, the depth of the chamber is a specified percentage of the thickness of the heat shield in the region of the gap.
- 3. The heat shield as claimed in claim 2, wherein the specified percentage is between about 10% to about 90%.
- 4. The heat shield as claimed in claim 1, wherein the chamber has a length and the heat shield has a width, the length of the chamber is a specified percentage of the width of the heat shield.
- 5. The heat shield as claimed in claim 4, wherein the specified percentage is between about 10% to about 80%.
- 6. The heat shield as claimed in claim 1, wherein the hot gas flows substantially parallel to said end surfaces of said segments, and said cooling holes extend obliquely to the direction of hot-gas flow.
- 7. The heat shield as claimed in claim 1, wherein said first side surface of each of said segments includes a recess, said cooling holes being defined within each of said segments extending from said recess to the end surfaces.
