Embodiment Construction

[0024] exist figure 1 , a cross-sectional view of a gas turbine component 1 with a device for impingement cooling comprising a surface structure 8 on a target surface 6 of an impingement cooling arrangement is shown.

[0025] The gas turbine component 1 comprises an outer surface 2 which is impinged by hot gases during operation and integrated cooling channels 3 for cooling. An impingement cooling element 4 extends within the cooling channel 3 , which divides the cooling channel 3 into a supply section 11 for coolant supply and a cooling section 12 in which the target surface 6 to be cooled is arranged. The impingement cooling element 4 is spaced apart from the target surface 6 to be cooled in the cooling section 12 of the component 1 . Furthermore, the impingement cooling element 4 comprises four impingement cooling holes 5 in the region shown, via which a cooling fluid can be conducted as a center point Z on the target surface 6 lying opposite the impingement cooling holes ...

Abstract

A device for cooling a component 1 to be cooled of a gas turbine / turbo machine having a hot-gas-impinged outer surface 2, a target surface of the component, and an integrated cooling passage 3, includes: an impingement cooling element 4 arranged within the cooling passage 3, the impingement cooling element having plural impingement cooling bores 5; and a surface structure arranged on the target surface 6. The impingement cooling element is spaced apart from the target surface 6 of the component and configured so as to conduct a cooling fluid as an impingement cooling jet is onto the target surface, such that the impingement cooling jet impinges on the surface structure 8.

Description

technical field [0001] The invention relates to a device for cooling a gas turbine / turbine component with a hot gas impingement outer surface and integrated cooling channels, in which an impingement cooling element with at least one impingement cooling hole is arranged. Background technique [0002] Various components of the gas turbine, such as blades, for example, are exposed to high temperatures of the combustion gases of the combustor. Furthermore, the efficiency of the gas turbine can be further improved by increasing the combustion temperature achieved in the combustor. However, such temperature increases have limitations due to the heat capacity of the components exposed to the hot gas. This applies in particular to the guide blades and moving blades of the turbine stages located downstream of the combustion chamber which are also subjected to major mechanical stresses. [0003] For this reason, special cooling methods are required in order to counteract component f...
