Abstract
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.
Claims20
A system for cooling components in an electronic display having a direct LED backlight comprising:
- a plate having a front and rear side and spaced apart from a rear surface of the LED backlight to define a channel where the plate is substantially parallel to the LED backlight;
- an electronic component attached the rear side of the plate;
- and
- a plurality of ribs placed between the rear surface of the LED backlight and the front side of the plate.
A system for cooling components in an electronic display having a direct LED backlight comprising:
- a plurality of ribs in conductive thermal communication with a rear surface of the LED backlight;
- a plate attached to the ribs;
- an electronic component separate from the LED backlight attached to the plate and in conductive thermal communication with the ribs;
- and
- a fan positioned to draw cooling air along the ribs.
A system for cooling components in an electronic display having a direct LED backlight comprising:
- a plurality of ribs in conductive thermal communication with a rear surface of the LED backlight;
- a plate attached to and in conductive thermal communication with the ribs;
- an electronic component separate from the LED backlight attached to the plate and in conductive thermal communication with the ribs;
- and
- a fan positioned to draw cooling air along the ribs,
- wherein the plate prevents cooling air from contacting the electronic component.
