Abstract:
1. A heat sink for distributing a thermal load, the heat sink comprising: two or more base plates connected and oriented around a central axis of the heat sink, at least one of the base plates receiving the thermal load, each base plate having thermal transport paths, the thermal transport paths oriented among the base plates so as to have the capability of accepting thermal transports having a plurality of lengths for thermal distribution between at least two of the base plates; heat-dissipating fins connected to each base plate, the heat-dissipating fins spaced apart in parallel and extending from each base plate towards the central axis of the heat sink; and thermal transports having a plurality of lengths and connected between the base plate receiving the thermal load and at least one other base plate so as to distribute the thermal load among the base plates of the heat sink.
