ABSTRACT:
A heat sink assembly (100) employs multiple heat sinks (401-403) that are juxtaposed to provide pneumatically coupled air flow pathways. At least one of the heat sinks (401) 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 (201) for the air flow, and at least two of the pneumatic pathways (201) 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 (200) 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 (300).
