Abstract
An automotive control module includes a plastic housing with a snap-fit metal cover. A printed circuit board is positioned within a cavity formed in the housing, and is attached to the housing with a plurality of fasteners. Resilient tabs are formed on side walls of the housing and grip a cover plate surface to define a snap-fit attachment. Once the cover is attached to the plastic housing, the printed circuit board is enclosed within the cavity between the cover and the housing. The cover includes a plurality of heat transfer fins and/or stamped indentations that form surfaces that are positioned in close proximity to the printed circuit board. The cover utilizes these fins and surfaces to form a heat sink for cooling electronics mounted to the printed circuit board.
