Abstract

Ein gekühltes Bauteil, insbesondere Turbinenschaufel (10, 10'), für Gasturbinen, weist zur effizienten Innenkühlung einen innenliegenden Kühlkanal (16) mit rundem Kanalquerschnitt auf, in welchen Kühlkanal (16) zur Ausbildung eines Kühlmittelwirbels eine Reihe von in Richtung der Längsachse des Kühlkanals (16) übereinander angeordneten, von einem gemeinsamen Kühlmittelkanal (15) ausgehenden Anspeisebohrungen (17) für das Kühlmittel im wesentlichen tangential einmünden.
Bei einem solchen Bauteil wird die Herstellbarkeit dadurch verbessert, dass die Anspeisebohrungen (17) überwiegend einen Bohrungsdurchmesser aufweisen, der kleiner ist als der halbe hydraulische Durchmesser des Kühlkanals (16), und dass zur Verbesserung der Ausbringungsrate beim Giessen des Bauteils (10') ausgewählte Anspeisebohrungen (25,..,27) einen Bohrungsdurchmesser aufweisen, der grösser ist als der halbe hydraulische Durchmesser des Kühlkanals (16).
