Isothermal heat sink with cross-flow openings between channels

摘要

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 plurality of channels for carrying coolant fluid. The plurality of channels are positioned in a first group and a second group such that coolant flow alternates across the member. At least one cross-flow opening is provided between at least some adjacent channels of the plurality of channels so that coolant flow can flow within the member between the first group of channels and the second group of channels.
