Claim:
1. A coolant-cooled electronic module comprising: a multi-component assembly comprising multiple electronic components disposed on a substrate; a module lid assembly, the module lid assembly comprising: an inner manifold element disposed over the lid assembly, the inner manifold element comprising opposite first and second main surfaces, the first main surface being configured to facilitate flow of coolant onto, at least in part, the coolant-cooled surfaces of the multiple thermally conductive elements, and including coolant supply openings disposed over the coolant-cooled surfaces of the thermally conductive elements, and coolant exhaust channels disposed, at least in part, adjacent to the coolant-cooled surfaces of the thermally conductive elements; an outer manifold element disposed over the inner manifold element and coupled to the module lid, with the inner manifold element between the outer manifold element and the module lid, wherein the inner manifold element and the outer manifold element define, at least in part, a coolant supply manifold over the second main surface of the inner manifold element, and the outer manifold element and the module lid define, at least in part, a coolant return manifold, the coolant supply openings being in fluid communication with the coolant supply manifold, and the coolant exhaust channels being in fluid communication with the coolant return manifold, and the coolant supply manifold, coolant supply openings, coolant exhaust channels, and coolant return manifold facilitate flow of coolant across the coolant-cooled surfaces of the thermally conductive elements; and wherein the inner manifold element further comprises a manifold wall extending from the second main surface, and the coolant supply manifold is defined within the manifold wall of the inner manifold element, and the coolant return manifold is defined, at least in part, outside and around the manifold wall of the inner manifold element.
