A low-cost, fan assisted cooling device (10) is disclosed. The cooling device (10) includes a heat mass (11) with a taper bore (14) therein adapted to receive a heat spreader (40) that has a shape that complement the taper bore (14). The heat mass (11) and the heat spreader (40) are made from dissimilar materials. A fastener (45) or the like can be used to urge the heat spreader (40) and the heat mass (11) into contact with each other. A plurality of vanes (21) are connected with the heat mass (11) and an inside surface (26) of the vanes defined a chamber (30) that surrounds the heat mass (11). A portion of each vane (21) is split into a plurality of fins (23) and both the vanes and the fins (21, 23) have a surface area that increase in a radially outward direction (r) from an axis (Z-Z) of the heat mass (11). <IMAGE> |
