Abstract
A slot impingement cooler is formed of a plurality of sets of foils in a stacked and registered array. In each set of foils, a first foil has supply slots that direct a flow of coolant, a second foil has a plurality of effective light-trap cavities, a third foil has return slots that return the flow of coolant, and an optional fourth foil has a plurality of effective light-trap cavities. The foils have registered supply manifold openings and registered return manifold openings therethrough.
Claims22
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,
