Abstract
Abstract A cold plate and an integrated circuit cooling module embodying a cross-hatch coolant flow distribution scheme. Cross hatch flow distribution is achieved by way of two sets of channels which run perpendicular to each other. The first set of channels is formed on a base plate (400). The second, perpendicular set is includes a set of inlet channels and a set of interleaved outlet channels formed on a distribution plate (600). In the preferred embodiment, the base and distribution plates are separated by an interposer plate (500) that has nozzles (502) which cause a liquid coolant to impinge, under pressure, on the floor of the base plate.
