Back pan cooling assembly for electronic display
First Claim
1. A back pan cooling assembly for an electronic display having a rear pan, the assembly comprising:
- a cooling back pan having a front surface and a rear surface, wherein said cooling back pan is positioned behind the rear pan;
a gap located between the cooling back pan and the rear pan;
a rear cover positioned on the cooling back pan to define a rear compartment formed between the cooling back pan and the rear cover which is substantially sealed to prevent ambient air from entering the rear compartment;
a port in the rear cover which accepts ambient air;
a fan positioned and configured to, when operated, cause a flow of ambient air to be ingested through the port and be exhausted through the gap; and
a power supply or microprocessor for driving the electronic display, the power supply or microprocessor placed at the rear surface of the cooling back pan within the sealed rear compartment and in conductive thermal communication with the cooling back pan;
wherein the fan is substantially sealed within the rear compartment such that ambient aft is not permitted to contact the power supply or microprocessor.

Abstract
Exemplary embodiments disclosed herein provide a back pan cooling assembly for an electronic display having a rear pan. A cooling back pan is preferably positioned behind the rear pan, the space between the cooling back pan and the rear pan defining a gap. A fan is positioned to cause a flow of ambient air through the gap. An electronic component for driving the electronic display may be placed in conductive thermal communication with the cooling back pan. A rear cover can be placed against the cooling back pan to define a sealed compartment which does not permit ambient air to enter. A port can be provided within the rear cover which allows ambient air to travel between the surroundings, the fan, and the gap.
