Abstract:
    A heat sink assembly (100) employs multiple heat sinks that are juxtaposed to provide pneumatically coupled air flow pathways. At least one of the heat sinks preferably includes an air circulator to force the air flow towards a periphery of the heat sink. A plurality of heat radiating surfaces provide pneumatic pathways for the air flow, and at least two of the pneumatic pathways are arranged substantially non-parallel. In this manner, the air is forced (i.e., when an air circulator is provided) radially from a center point of the heat sink toward a periphery. Similarly, the air is directed (i.e., when an air circulator is not provided) toward a central locale from the periphery of the heat sink.
