  • Apparatus and method for an active antenna heat sink
    Patent number: 9161478
    Abstract: Heat dissipation in vertically arrayed host device configurations can be improved through inclusion of heat sinks having split-stream fin architectures. 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.
