Abstract

An internally coolable component for a gas turbine with at least one cooling duct, on the inner surface of which swirl elements are arranged in the form of turbulators which extend transversely with respect to the main flow direction of a coolant is provided. In order to reduce pressure losses for the coolant in the cooling duct, pins with different heights are set up between the turbulators.

Claims5

Dependent claims

An internally coolable component for a gas turbine, comprising

at least one cooling duct, on the inner surface of which are arranged turbulence elements in the form of turbulators extending transversely with respect to the main flow direction of a coolant and between which are arranged pins of different heights,
wherein the height of the pins is less than the height of the cooling ribs, and
wherein successive pins, as seen in the main flow direction of the coolant, are of different heights.

Dependencies are inferred from the claim text.
