Each aperture of the plurality of apertures is configured to emit a cooling fluid therethrough. The component also includes an outer wall spaced from the inner wall. The outer wall and the inner wall extend along a longitudinal axis of the component. The component further includes a plurality of angled walls extending between the inner wall and the outer wall. The plurality of angled walls define a plurality of angled channels in fluid communication with the plurality of apertures. Each angled wall of the plurality of angled walls extends at an acute angle relative to the longitudinal axis. ## Claims ### Claim 1 A component configured for impingement cooling, said component comprising: an inner wall defining a plurality of apertures, each aperture of said plurality of apertures configured to emit a cooling fluid therethrough;
