Abstract
In an apparatus for impingement cooling, in which a cooling surface and a cover surface are disposed parallel to one another, trapezoidal profiles that are open respectively on the narrow side and connected to one another at a constant distance from the cooling surface are disposed crosswise to the flow direction of the cooling air. A side of the trapezoid facing the cooling surface is provided with at least one row of perforations and forms a gap of a constant height with the cooling surface. Open sides of the trapezoid located opposite the cover surface form feed openings for the cooling air, and open sides of the trapezoids located opposite the cooling surface form overflow openings. The feed opening is much larger than the cross-section of a perforation. The cross-section of the return flow conduit is much larger than the overflow opening, and this opening is, in turn, much larger than the cross-section of the gap.
