Abstract:
1. A heat sink for dissipating a thermal load, the heat sink comprising: a heat sink base capable of receiving a thermal load from a thermal source; heat-dissipating fins mounted on the heat sink base, each heat-dissipating fin enclosing a hollowed cavity inside the heat-dissipating fin; a thermal transport within the hollowed cavity of each heat-dissipating fin, the thermal transport capable of convectively transferring the thermal load along a convective heat path within each heat-dissipating fin; a pair of electrodes inside each heat-dissipating fin, the pair of electrodes electrically connected to the thermal transport within each heat-dissipating fin for generating an electric current through the thermal transport; and a magnet mounted adjacent to the heat-dissipating fins for generating a magnetic field through the thermal transport within each heat-dissipating fin, the magnetic field passing through the electric current and oriented to induce a force on the thermal transport along the convective heat path.
