摘要： 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.

摘要： A cooling passage arrangement is provided inside a hollow-cast cast part, with a flow region, delimited by at least two spaced apart cast-part walls, for a cooling medium. The flow region is divided in the flow direction into two cooling passages by at least one rib line which is connected to the two cast-part walls. At least one gap is provided along the at least one rib line. At the least one gap, two rib ends are oppositely disposed a distance apart, of which one rib end has a contour in the style of a “wish bone -“Y”-cross-section”.
