Patent ID: 7472741

Claim:
A slot impingement cooler, comprising: a foil set comprising a first set of foils in a stacked and registered array and arranged to provide cooling at a cooler surface, wherein the first set of foils includes in order a first foil having a first-foil supply manifold opening through the first foil, a first-foil return manifold opening through the first foil, and a plurality of first-foil supply slots extending from the first-foil supply manifold opening to the cooler surface, a second foil having a second-foil supply manifold opening through the second foil, a second-foil return manifold opening through the second foil, and a plurality of second-foil effective light-trap cavities communicating with the cooler surface; and a third foil having a third-foil supply manifold opening through the third foil, a third-foil return manifold opening through the third foil, and a plurality of third-foil return slots extending from the third-foil return manifold opening to the cooler surface, wherein the first-foil supply manifold opening, the second-foil supply manifold opening, and the third-foil supply manifold opening are in registry to define a supply manifold, and wherein the first-foil return manifold opening, the second-foil return manifold opening, and the third-foil return manifold opening are in registry to define a return manifold.
