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.

Abstract: The cooling of a heat generating component mounted outside of the main portion of an enclosure that is cooled using an airstream created by an active air handler is disclosed. The invention is preferably used to cool components such as displays that generate heat, but which are mounted outside the enclosure that houses the main electronics package. The disclosed system, permits inlet air to enter via a vent, and a first duct formed by a baffle routes the inlet air along the back of the displays, removing excess heat. The air is then channeled by a second duct to an area adjacent the enclosure. Since the airstream within the enclosure has created a low pressure area, the passive air stream infiltrates the enclosure and mixes with the main airstream. The disclosed system thus cools the remotely mounted components passively, without requiring additional air handlers or diminishing the pressure and velocity within the enclosure.
