Patent ID: 7762314

Claim:
A cooling apparatus comprising: a manifold structure comprising a plurality of inlet passageways for impinging coolant onto a surface to be cooled, and a plurality of outlet passageways for exhausting coolant after impinging on the surface to be cooled, the inlet passageways and the outlet passageways being interleaved in the manifold structure over the surface to be cooled for injecting coolant onto and exhausting coolant from, respectively, the surface to be cooled through a common edge of the manifold structure, the interleaved inlet and outlet passageways comprising alternating inlet and outlet passageways at the common edge of the manifold structure, and the common edge of the manifold structure being in opposing relation to the surface to be cooled; and wherein the manifold structure further comprises a coolant inlet plenum and a coolant outlet plenum, with coolant passing through the plurality of inlet passageways from the coolant inlet plenum in a first direction perpendicular to the surface to be cooled, and coolant passing through the plurality of outlet passageways to the coolant outlet plenum in a second direction perpendicular to the surface to be cooled, the first and second directions being opposite directions, and wherein the manifold structure, including the coolant inlet plenum and coolant outlet plenum, is contained within a rectangular volume defined by a projection of the common edge; and wherein the manifold structure comprises an assembled plurality of manifold plates, at least some manifold plates of the assembled plurality of manifold plates comprising stand-offs, the stand-offs defining in part the plurality of inlet passageways and the plurality of outlet passageways of the manifold structure.
