A heat exchanger assembly for an electronic image assembly placed within a housing where ambient air surrounds the exterior of the housing and a rear plate may be placed behind a backlight to create a channel. An ambient air fan may be placed between two portions of a heat exchanger to force ambient air through the heat exchanger. The fan may also be positioned to also force ambient air through the channel. A circulating gas fan may also be placed within the housing to force circulating gas through at least one portion of the heat exchanger.
