Patent ID: 8305759

Claim:
A liquid cooled electronic device, comprising: one or more electronic components capable of generating heat disposed in an interior space of a liquid-tight container; a liquid distribution unit configured to cool at least one of said one or more electronic components by distributing a dielectric liquid to flow in a liquid state over and in direct contact with said at least one electronic component through assistance of gravity so as to absorb heat generated by said at least one electronic component; a liquid sump beneath the one or more electronic components configured to receive said liquid that flows off said at least one electronic component, the liquid sump is open to and defined by the interior space; the liquid that flows over the at least one electronic component is in the same state as the liquid in the liquid sump; a heat exchange unit configured to cool said liquid that is received by said liquid sump; and a liquid pumping unit configured to pump said liquid received by said liquid sump through said heat exchange unit for cooling of said liquid and to return said liquid back to said liquid distribution unit so as to reuse said liquid for further cooling of said at least one electronic component.
