CONDENSER STRUCTURES WITH FIN CAVITIES FACILITATING VAPOR CONDENSATION COOLING OF COOLANT

摘要

Vapor condensers and cooling apparatuses are provided which facilitate vapor condensation cooling of a coolant employed in cooling an electronic device. The vapor condenser includes a thermally conductive base structure with a plurality of condenser fins extending from the base structure. The condenser fins have a proximal end coupled to the base structure and a remote end remote from the base structure. At least one exposed cavity is provided within each condenser fin extending from the remote end towards the proximal end. The exposed cavities are sized to provide greater condenser fin surface area for facilitating vapor condensate formation, and thereby facilitate cooling of an electronic device using a two-phase coolant.
