Abstract
The cold plate is a multiple layer structure with an inlet manifold for pressurized coolant liquid. The manifold is covered by a nozzle plate which directs liquid coolant jets against the mounting plate. The mounting plate carries the device to be cooled. The high velocity liquid jets impinge directly on the mounting plate to minimize the boundary layer to enhance heat transfer from the mounting plate to the liquid coolant.
