Abstract
This invention provides a heat sink for dissipating heat from an electronic component to be cooled by air flow. The heat sink includes a base configured to be mounted to the electronic component to receive heat transferred from the electronic component. The base has a center extending along the direction of air flow. The heat sink also includes a plurality of fins projecting from the base. Each of two adjacent fins is positioned on opposite sides of the center of the base and is spaced laterally from the center of the base. The adjacent fins define a gap extending across the center of the base. The gap between the adjacent fins reduces the temperature increase of air flowing adjacent the center of the base. This invention also provides a circuit assembly and a method for cooling an electronic component.
