An electronic image assembly cooling system includes an enclosure having an electronic image assembly mounting space located therein. A closed loop gas circulation path and an open loop air flow path are provided to effectuate cooling. A common heat exchanger is located in gaseous communication with both the closed loop gas circulation path and the open loop air flow path. The closed loop gas circulation path encircles the electronic image assembly mounting space within the enclosure, while the open loop ambient air flow path facilitates removal of heat from gas circulating within the closed loop gas circulation path. A second open loop air flow path may pass through the enclosure and through a gap located rearward of the electronic image assembly mounting space to assist with heat removal when an electronic image assembly is mounted in the enclosure.
