First Claim
Patent Images
1. A system for thermally controlling an electronic display having a posterior display surface, the system comprising:
- a constricted convection plate placed posterior to the posterior display surface;
two side panels placed adjacent to the constricted convection plate and the posterior display surface, defining a constricted convection channel having an entrance and an exit;
a plurality of fans placed across the exit and adapted to draw air in a substantially uniform flow through the constricted convection channel; and
a plurality of access apertures through the constricted convection plate.

Abstract
Preferred embodiments provide a cooling system for an electronic display. A constricted convection channel is used to force cooling air against a posterior surface of the electronic display. Fans may be used to propel or pull air through the constricted convection channel in a substantially uniform manner. A refrigeration unit or thermoelectric module may be employed to cool or heat the air traveling through the constricted convection channel. Some embodiments include a closed loop which extracts heat (or adds heat) to the front display surface.
