US Patent 7201217 Cold plate assembly

A cold plate assembly, which in one embodiment includes a manifold layer comprising one or more input coolant sub-manifold channels and one or more output coolant sub-manifold channels. A metering plate having a plurality of orifices defined there through is disposed adjacent the manifold layer in spaced relation to a cover plate. A core layer is disposed between the metering plate and cover plate, the core layer comprising corrugated fin material. The input sub-manifold channels and output sub-manifold channels are in fluid communication through fluid paths passing through the orifices in the metering plate and the core layer.
