Abstract:
1. A cooling apparatus comprising: a housing configured to at least partially surround and form a sealed compartment about an electronic subsystem comprising a plurality of electronic components to be cooled; a dielectric fluid disposed within the sealed compartment, wherein the electronic subsystem's plurality of electronic components to be cooled are immersed within the dielectric fluid; a liquid-cooled vapor condenser, the liquid-cooled vapor condenser comprising a plurality of thermally conductive condenser fins extending within the sealed compartment in an upper portion of the sealed compartment, the plurality of thermally conductive condenser fins facilitating cooling and condensing of dielectric fluid vapor rising to the upper portion of the sealed compartment; and a filler material disposed within the sealed compartment and reducing an amount of dielectric fluid required within the sealed compartment to achieve immersion of the electronic subsystem's plurality of electronic components within the dielectric fluid, the filler material comprising a shaped surface, the shaped surface being configured to direct dielectric fluid vapor within the sealed compartment towards the plurality of thermally conductive condenser fins.
