Abstract:
1. A heat shield for guiding a hot gas, comprising: a support structure having an inlet channel for a coolant flow; a plurality of heat shield elements mounted to the support structure, each heat shield having a hot gas wall in contact with the hot gas and a plurality of side walls which extend from the hot gas wall toward the supporting structure to form an internal space that receives the coolant flow; a plurality of cooling gaps formed by spaces between adjacent heat shields; a sealing element which provides mechanical damping that is arranged between the supporting structure and the side walls, said side walls and said supporting structure being connected through the sealing element, said side walls not being in direct contact with said supporting structure; and a coolant discharge channel that is formed within a portion of the support structure so as to direct the coolant flow from the internal space under the sealing element to the cooling gaps.
