Claim Text:
1. A cooling apparatus comprising: an enclosure comprising a compartment accommodating at least one electronic component to be cooled; a dielectric fluid circulating through the compartment and at least partially immersing the at least one electronic component to be cooled; a liquid-cooled heat sink associated with the enclosure and cooling a plurality of fins disposed in an upper region of the compartment, the plurality of fins facilitating heat transfer to the liquid-cooled heat sink from the at least one electronic component via the dielectric fluid within the compartment; a pump disposed external to the enclosure and coupled in fluid communication with the compartment to facilitate pumped dielectric fluid flow into and out of the enclosure through the compartment, the pumped dielectric fluid flow through the compartment enhancing heat transfer from the at least one electronic component to the liquid-cooled heat sink via the plurality of fins, the pumped dielectric fluid flow at least partially immersing the plurality of fins; a dielectric fluid inlet and a dielectric fluid outlet associated with the enclosure to allow the pumped dielectric fluid flow into and out of the enclosure and through the compartment; and a baffle disposed within the compartment and directing the pumped dielectric fluid flow into the enclosure across the at least one electronic component, and then across the plurality of fins downstream of the least one electronic component, before exiting through the dielectric fluid outlet.
