Apparatus and method for an active antenna heat sink

摘要

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.

主权项

1. A heat sink comprising:
a heat dissipating face; a first set of fins extending across the heat dissipating face, wherein a first set of channels are formed between individual fins within the first set of fins; a second set of fins extending across the heat dissipating face, wherein a second set of channels are formed between individual fins within the second set of fins, the second set of channels fins angled toward the first set of fins; and a conduit receding into the heat dissipating face, the conduit separating the first set of fins from the second set of fins, wherein the conduit provides a pathway in which convection cooling air flows into, or out of, the first set of channels and the second set of channels.
