Electronics package with radial heat sink and integrated blower

摘要

An electronics package (10) includes an enclosure (50) and one or more thermal energy generating components disposed in the enclosure (50). A radial heat sink (24) is disposed in the enclosure (50) including a blower (28) disposed in the radial heat sink (24) and a plurality of fins (34) extending from a periphery of the blower (28) toward a perimeter (38) of the radial heat sink (24). The plurality of fins (34) define a plurality of channels (40) having a plurality of channel exits at the perimeter (38) of the radial heat sink (24). The radial heat sink (24) is configured to dissipate thermal energy from the one or more components (14, 16, 18, 20, 22) which are arranged around the heat sink (24) according to heat flux requirements of each component. The radial heat sink (24) has areas (42) of relatively high flux capacity for receiving components having relatively high heat flux requirements and areas (44) of relatively low flux capacity for receiving components having relatively low heat flux requirements.
