System for Cooling an Electronic Display
First Claim
1. A cooling system for an electronic display assembly comprising:
- an isolating structure placed behind the electronic image assembly;
a channel defined by the space between the isolating structure and the electronic image assembly;
a power module having electronic components on a first side and a baseplate on the second side, where the power module is attached to the isolating structure so that the baseplate is within the channel and the electronic components are outside the channel; and
a fan positioned so as to draw ambient gas through the channel.

Abstract
A system for cooling an electronic display where an isolating structure may be used to allow ambient air to cool power modules. The isolating structure substantially prohibits containments which may be present within the ambient air from contacting sensitive electrical components on the power modules or otherwise. A gasket may be used to seal the interface between the power modules and the isolating structure. Heat sinks may be placed in thermal communication with the power supplies and fans may draw air through a narrow channel in which the heat sinks are located. In some embodiments the narrow channel may have the opposing surface of the channel defined by the rear portion of an LED assembly. Exemplary embodiments may use the ambient air to cool both the power modules and a closed loop of isolated gas within the electronic display.
