Abstract
A heat sink includes a blower located in the heat sink and a plurality of fins extending from a periphery of the blower toward a perimeter of the heat sink. The plurality of fins define a plurality of channels each having a channel inlet located at the blower and a channel exit located at the perimeter of the heat sink. The plurality of channels vary in length around the perimeter of the heat sink A velocity of an air flow from the blower at each channel inlet is substantially equal for each channel of the plurality of channels, and a total pressure drop from the channel inlet to the channel exit is substantially equal for each channel of the plurality of channels.
