Expanded heat sink for electronic displays

摘要

A system for cooling various components of an electronic display. One or more heat-generating components are preferably placed in thermal communication with a plate and ribs. One or more fans are placed to draw cooling air along the ribs to remove the heat removed from the component. Some embodiments may place the electronic image assembly in thermal communication with the ribs to remove heat from the electronic image assembly. Exemplary embodiments have power modules and the electronic image assembly in thermal communication with the ribs. Conductive thermal communication is established between the ribs and the components in the exemplary embodiments.
