Pump-enhanced, immersion-cooling of electronic compnent(s)

Abstract

Cooling apparatuses and methods of fabricating thereof are provided which facilitate pumped immersion-cooling of an electronic component(s). The cooling apparatus includes an enclosure having a compartment accommodating the electronic component(s), and dielectric fluid within the compartment at least partially immersing the electronic component(s). A liquid-cooled heat sink is associated with the enclosure to cool at least one cooling surface associated with the compartment, and facilitate heat transfer to the heat sink from the electronic component(s) via the dielectric fluid. A pump is disposed external to the compartment and in fluid communication therewith to facilitate pumped dielectric fluid flow through the compartment. The pumped dielectric fluid flow through the compartment enhances heat transfer from the electronic component(s) to the liquid-cooled heat sink via the cooling surface(s). In one implementation, the pumped dielectric fluid flow provides two-phase cooling to the electronic component(s) via flow boiling.
