ABSTRACT:
Throughflow openings are provided for a cooling medium in a coolable component. The throughflow opening comprises an insert that reduces the size of the first opening cross-section to a second opening cross-section, and that is released from the first opening if the second opening cross-section becomes blocked as a result of a local temperature rise and a thermally unstable joining between the insert and the component, being mounted in a first opening. The present throughflow opening greatly reduces the risk of damage to components to be cooled, in particular turbine blades, as a result of fine throughflow openings becoming blocked.
