Abstract
A two-phase cold plate includes an outer enclosure having a fluid inlet and a fluid outlet each fluidly coupled to a fluid pathway, an inner enclosure having a vapor cavity and a vapor outlet, and one or more wicking structures disposed in the outer enclosure. The one or more wicking structures fluidly couple the fluid pathway of the outer enclosure with the vapor cavity of the inner enclosure and the one or more wicking structures comprise a plurality of nucleation sites configured to induce vaporization of a cooling fluid and facilitate vapor flow into the vapor cavity of the inner enclosure.
