ABSTRACT:
Heat sinks for dissipating a thermal load are disclosed that include: 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; and 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. Heat sinks for dissipating a thermal load may also include: a pair of electrodes inside each heat-dissipating fin electrically connected to the thermal transport 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, the magnetic field passing through the electric current and oriented to induce a force on the thermal transport along the convective heat path.
