Abstract:
A cooled flow deflection apparatus for a fluid-flow machine which operates at high temperatures, which flow deflection apparatus has a leading edge and a trailing edge and an interior defined between the leading edge and the trailing edge, a number of parallel-running cooling channels formed in the interior, which are separated from one another by separating walls for a cooling fluid to pass through, wherein the separating walls are in the form of separate inserts which can be pushed into the flow deflection apparatus subsequently;the cooling fluid flows in mutually opposite directions in two adjacent cooling channels, the cooling fluid being deflected from the outlet of the one cooling channel into the inlet of the other cooling channel by means of a deflection device, and the deflection being produced by a separating wall which is bent into a U-shape; and the separate inserts being spaced apart from each other successively from the leading edge to the trailing edge and defining at least one path through the interior from the leading edge to the trailing edge.
