System for Cooling an Electronic Display

摘要

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.
