ABSTRACT:
A fan with heat sink comprises a plurality of closely spaced sheet metal fins closely proximate to the blade tips of an axial flow fan. The high velocity air and blade tip vortices cooperate to provide exceptional heat transfer. The metal fins are retained in a fan duct comprising a metal cylinder under high force for good heat transfer. In one embodiment of the invention, the fins are formed with a conical displacement, lessening their diameter, and are flattened and spread in the fan duct, to have high contact pressure for good heat flow. In another embodiment of the invention, the heat sink fins are formed from strip, for very low scrap, and are wrapped around reinforcing rings so that they may be installed in the fan duct with high force for good thermal contact. In another embodiment of the invention, the fan duct comprises a plurality of posts rising from a cold plate, and the heat sink fins are pressed thereon with high force.
