Abstract
The present application provides an impingement cooling system for use with a contoured surface. The impingement cooling system may include an impingement plenum and an impingement plate with a linear shape facing the contoured surface. The impingement surface may include a number of projected area thereon with a number of impingement holes having varying sizes and varying spacings.
Claims20
An impingement cooling system for use with a non-planar contoured surface of gas turbine with multiple irregular depressions and projections, comprising:
- a nozzle with an impingement plenum in communication with a cooling flow in a cooling conduit, the cooling flow flowing through the impingement plenum in a first direction;
- an impingement plate facing the contoured surface;
- the impingement plate comprising a substantially flat shape;
- a cover plate positioned substantially parallel to the impingement plate, wherein the impingement plenum comprises a cavity defined between the impingement plate and the cover plate, such that the cooling flow impacts the cover plate and flows through the impingement plate in a second direction;
- the impingement plate comprising a plurality of projected areas thereon, the projected areas corresponding to the multiple irregular depression and projections of the contoured surface;
- wherein each of the plurality of projected areas comprises a plurality of impingement holes with varying sizes and varying spacings between the impingement holes for each of the plurality of projected areas.
