HEAT SHIELD ELEMENT

摘要

The invention relates to a heat shield element (26), particularly for a combustion chamber (4) of a gas turbine (1). The heat shield element (26) comprises a wall (47) with a hot side (35) and a cold side (33) opposite the hot side (35). For cooling purposes, the cold side (33) is cooled with a cooling agent (K), for example, cold air. The cold side (33) has several turbolators (23) for improving heat exchange between the wall (47) and the cooling agent (K), wherein the turbolators (23) merge with one another so that a network of intersecting turbolators (23) is formed on the cold side (33). The turbolators (23) enhance cooling efficiency and augment the rigidity of the wall (47) so that a smaller wall thickness (d) can be realized. The invention also relates to a combustion chamber (4) that is lined with said heat shield elements (26) and to a gas turbine (1) with a combustion chamber (4).
