Abstract

Es ist ein System (100) zur Schaffung einer Kühlung einer Turbinenkomponente (34), die eine, zu kühlende Region enthält, geschaffen. Eine Aussparung ist innerhalb der zu kühlenden Region ausgebildet und enthält eine Innenfläche. Wenigstens ein Stützvorsprung (48) erstreckt sich von der Innenfläche aus. Der wenigstens eine Stützvorsprung (48) enthält ein freies Ende. Eine Abdeckung (54) wird mit der zu kühlenden Region verbunden, so dass eine innere Oberfläche (57) der Abdeckung (54) mit dem freien Ende des wenigstens einen Stützvorsprungs (48) derart verbunden ist, dass wenigstens ein Kühlfluidkanal innerhalb der zu kühlenden Region ausgebildet ist.
