Abstract
Beschrieben wird eine Kühlvorrichtung für ein Deckband (1) einer Gasturbinenschaufel, mit einem in dem Deckband (1) vorgesehenen Kühlkanalsystem, das radial zur Gasturbinenschaufel einseitig offene Kühlkanäle (4) aufweist und mit einer Deckplatte (2) abgeschlossen ist.A cooling device for a shroud (1) is described Gas turbine blade, with one provided in the shroud (1) Cooling channel system, the cooling channels open on one side radially to the gas turbine blade (4) has and is completed with a cover plate (2).
Die Erfindung zeichnet sich dadurch aus, dass zwischen Deckplatte (2) und den einseitig offenen Kühlkanälen (4) eine Prall-Kühlplatte (5) derart vorgesehen ist, dass die Prall-Kühlplatte (5) auf den einseitig offenen Kühlkanälen (4) aufliegt, kraftschlüssig gegen diese gepresst ist und mit der Deckplatte (2) einen Zwischenraum einschließt. The invention is characterized in that a baffle cooling plate (5) is provided between the cover plate (2) and the cooling channels (4) open on one side in such a way that the baffle cooling plate (5) rests on the cooling channels (4) open on one side. is non-positively pressed against this and encloses an intermediate space with the cover plate (2).
