Abstract
Pins (,) consisting of a material having high thermal conductivity are introduced, alternately with blow-out orifices (,) for a coolant (,), into the material, to be cooled, of a component (,), in such a way that said pins project out of the component on the cooling side (,) of the latter. These pins are cooled in the region which projects out of the component whilst heat is supplied to them in the region which is embedded in the component. The alternating arrangement with blow-out orifices ensures that the flow (,) passes around the pins. This point is important particularly when the pins are arranged in a narrow gap, such as occurs especially in the cooling of the trailing edges of gas turbine blades. The necessary number of blow-out orifices and therefore the coolant consumption is reduced.
