Application # 2018/0042134. ELECTRONIC DISPLAY WITH COOLING - Patents.com
United States Patent Application 20180042134
Dunn; William ; et al. February 8, 2018
An electronic display including an electronic image assembly and a cooling system for an electronic image assembly. A closed loop gas circulation path and an open loop ambient 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 ambient air flow path. The open loop ambient air flow path facilitates removal of heat from gas circulating within the closed loop gas circulation path. A cooling channel may be located behind a rear portion of the electronic image assembly to further enhance cooling via the circulation of ambient air therein.
