    Abstract: The present invention generally relates to an array backframe with integral manifolding for high performance fluid cooling of devices. The integral manifolding of the array backframe is designed to perform three functions. First, the array backframe parallelizes the fluid paths to provide uniform, cool supply fluid to every device in the array. Second, the array backframe minimizes the parasitic heat losses between supply and exhaust by use of an isolation cavity. Third, the array backframe collapses hundreds of fluid lines into a single internal manifold to enhance modularity while also serving as a structural support member.

The split-stream fin architecture includes two or more sets of angled fins separated by a central conduit, which allows for more efficient inflow and/or expulsion of convection cooling air over the heat sink. The split-stream fin arrangement may include inwardly angled fins in order to draw convection cooling air inwards from horizontal inlets, in which case warm exhaust is expelled through the central conduit. Conversely, the split-stream fin arrangement may include outwardly angled fins, which draw convection cooling air from the central conduit, and expel warm air through horizontal exhausts. The split-stream fin arrangements function well when host devices are configured horizontally, which allows for more flexible host device configurations.

  • Patent number: 8811010
    Abstract: An exemplary electronic device includes a container, a fan assembly and a duct received in the container. The fan assembly includes a centrifugal fan and a fin group thermally contacting an electronic component in the container. An air passage is defined between each adjacent fins of the fin group. An inner side of the fin group is mounted on an outlet of the centrifugal fan. A bottom surface of the fin group and an inner surface of the container cooperatively define a first channel therebetween. The duct includes an inlet and a first outlet. Airflow guided by the centrifugal fan flows through the duct and the first channel to cool a bottom end of the fin group, then is absorbed into the centrifugal fan from an inlet of the centrifugal fan, and then flow through the air passages of the fin group to cool a central portion the fin group.

  • Patent number: 8807204
    Abstract: A system for cooling a heat generating device comprises a heat sink and a plurality of ion emitter elements that form an electrohydrodynamic (EHD) air flow device. The heat sink has a base disposed in thermal communication with a heat generating device, such as a processor. A plurality of heat sink fins is coupled to electrical ground to form ion collectors. Ion emitter elements are disposed in a non-planar pattern along first ends of the plurality of fins so that each ion emitter element is equidistant from the first end of a nearest fin. A power supply applies an electrical potential between the plurality of ion emitter elements and the plurality of fins to induce a flow of ions that cause airflow across the heat sink.
