Abstract
A two-phase cold plate that includes a manifold body having a fluid inlet and a fluid outlet each fluidly coupled to a fluid pathway housed within the manifold body and a vaporization structure housed within the manifold body such that the fluid pathway is disposed over the vaporization structure. The vaporization structure includes a cavity cover, a porous surface, a vapor cavity disposed between the cavity cover and the porous surface, and one or more porous feeding posts extending between the cavity cover and the porous surface. The one or more porous feeding posts fluidly coupled the fluid pathway with the porous surface of the vaporization structure and the porous surface includes a plurality of nucleation sites configured to induce vaporization of a cooling fluid and facilitate vapor flow into the vapor cavity of the vaporization structure.
