Abstract
A cooling system for an electronic display. Transparent cooling chambers are used to extract heat from the front display surface of an electronic display. A refrigerated air source is in gaseous communication with the cooling chamber. Additional fans may be used to cool other components of the electronic display. Multiple displays may be used where each display and the refrigerated air source is housed within the housing. The housing contains air inlet and air exhaust ports. An air curtain device may be used with some embodiments. An open-loop, closed-loop, or both types of designs may be used with the cooling chambers. Temperature sensors may allow the refrigerated air source(s) to be selectively engaged depending on the temperature of the air within the cooling chamber or the temperature of the front display surface. Ambient temperature sensors may also direct the switch between open and closed loops.
