A method for cooling an electronic image assembly using ambient gas. Exemplary embodiments of the method include the steps of circulating a closed loop of circulating gas around the electronic image assembly, directing a flow of ambient air through a first manifold, allowing the flow of ambient air to cross the flow of circulating gas without allowing the two to mix, directing the flow of ambient air behind the electronic image assembly and directing the flow of ambient air through a second manifold. The circulating gas may be used to cool a front portion of the electronic image assembly. A cross through plate may be used to allow the ambient gas and circulating gas to cross paths without mixing. A heat exchanger may be included with some embodiments of the method.
