Abstract
Apparatus for cooling an electronic device, and a resultant fluid-cooled electronic apparatus are provided. In one embodiment, the apparatus includes a heat sink member with a surface for making thermal contact with the electronic device. The heat sink member has a first plurality of channels for carrying coolant fluid. The first plurality of channels are positioned in a first group and a second group such that coolant flow alternates across the member. The heat sink member further includes a second plurality of channels disposed above the first plurality of channels such that the first and second pluralities of channels comprise tiered channels. The second plurality of channels further includes a third group of channels and a fourth group of channels, wherein the third group of channels and fourth group of channels are positioned generally alternately across the member so that coolant flow also alternates direction therebetween.
