Abstract
A cooling system and a method for cooling an electronic display. A preferred embodiment utilizes a closed loop cooling system in a constricted convection cooling setup to remove heat from the backlight of a display assembly. Cooling air can be pulled or pushed through a gap between the display (or backlight) and a rear cooling chamber. The resulting warm air can then be exhausted out of the display housing. The cooling air may be air conditioned or may be exposed to a thermoelectric device. A thermostat may be used so that cooling fans are only energized when the temperature reaches a predetermined point.
Claims20
A system for cooling a display comprising:
- a closed-loop cooling system surrounding the display, the cooling system having a rear cooling chamber placed posterior to the display, the space between the rear cooling chamber and the display defining a gap;
- and
- a fan positioned to create a flow of ambient air through the gap.
A display assembly comprising:
- an electronic display;
- a closed-loop cooling system surrounding the display, the cooling system having a rear cooling chamber placed near the display posterior, the space between the rear cooling chamber and the display defining a gap;
- a first fan below the rear cooling chamber and adapted to ingest ambient air;
- and
- a second fan adapted to force air through the gap.
A display assembly comprising:
- a housing;
- an LCD stack within the housing;
- an LED backlight placed behind the LED stack and having a posterior surface;
- a closed-loop cooling system surrounding the LCD stack and LED backlight, the cooling system having a rear cooling chamber placed near the posterior surface of the LED backlight, the space between the rear cooling chamber and the posterior surface of the LED backlight defining a gap;
- a first fan below the rear cooling chamber and adapted to ingest ambient air into the housing;
- a second fan adapted to force air through the gap;
- and
- an exhaust aperture adapted to exhaust air that has passed through the gap.
