ABSTRACT:
A heat sink having an annular conductive section disposed between a brake drum and a wheel assembly with a plurality of convective sections extending from the conductive section through a like number of hand-hold apertures formed in the wheel assembly. In an alternative embodiment, the heat sink has a hollow section formed in each convective section extending into the conductive section where the hollow section is at least partially filled with a heat conductive material that undergoes a phase change to further enhance the heat transfer from the conductive section to the convective section.
