Transonic and supersonic two-phase flow for electronic cooling

A system for cooling a heat-generating component comprising:

• first plate defining an inlet, an outlet, and an envelope for the heat-generating component;
• a second plate mounted against the first plate and defining a converging-diverging (CD) nozzle therein, with an inlet end of the CD nozzle in fluid communication with the inlet of the first plate, with an outlet end of the CD nozzle in fluid communication with the outlet of the first plate, and wherein the envelope for the heat-generating component is positioned between the inlet and the outlet to ensure thermal contact with a supersonic/transonic, two-phase fluid flow emerging from a throat of the CD nozzle;
• and
• a cover plate mounted to the second plate opposite from the first plate, configured to securely enclose a fluid path from the inlet of the first plate, to the inlet end of the CD nozzle of the second plate, through the throat of the CD nozzle of the second plate, to the outlet end of the CD nozzle of the second plate, to the outlet of the first plate.
