Abstract:
1. A cooling apparatus comprising: a housing at least partially surrounding and forming a fluid-tight compartment about at least one electronic component to be cooled; a pool of fluid disposed within the fluid-tight compartment and filling a lower portion thereof, the pool of fluid having an upper surface, wherein the at least one electronic component to be cooled is surrounded by and immersed within the pool of fluid, below the upper surface thereof, and cooled by boiling of the fluid; a vapor-condenser comprising a plurality of thermally conductive condenser fins, the plurality of thermally conductive condenser fins extending within the fluid-tight compartment in a vapor region of the fluid-tight compartment in an upper portion thereof, and spaced separate from and disposed above the upper surface of the pool of fluid forming a gap between the upper surface of the pool of fluid and the plurality of thermally conductive condenser fins, the plurality of thermally conductive condenser fins facilitating condensing of vapor in the vapor region, and the return thereof as droplets falling downwards to the pool of fluid in the lower portion of the fluid-tight compartment; and at least one wicking component disposed within the vapor region of the fluid-tight compartment separate from and above the pool of fluid and in physical contact with at least one thermally conductive condenser fin of the plurality of thermally conductive condenser fins extending within the fluid-tight compartment, the at least one wicking component extending at least partially in between adjacent thermally conductive condenser fins of the plurality of thermally conductive condenser fins within the vapor region of the fluid-tight compartment and the at least one wicking component, spaced separate from the pool of fluid, drawing condensed fluid from at least one surface of the at least one thermally conductive condenser fin to facilitate return thereof as the droplets falling downwards to the pool of fluid in the lower portion of the fluid-tight compartment.
