Claim of US Patent No. 10,660,245

13. A back pan cooling assembly for an electronic display having a rear pan with a pair of vertical edges and a pair of horizontal edges, the assembly comprising:a cooling back pan having a pair of vertical edges substantially aligned with the vertical edges of the rear pan and a pair of horizontal edges which are substantially aligned with the horizontal edges of the rear pan;
a gap defined between the cooling back pan and rear pan which extends to each horizontal edge to define a pair of horizontal edge gaps and to each vertical edge to define a pair of vertical edge gaps;
a fan positioned to cause ambient air to flow through the vertical edge gaps and the horizontal edge gaps;
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 sealed to prevent ambient air from entering the rear compartment;
a port within the rear cover;
an open loop gaseous pathway defined by gaseous communication between the port, fan, the horizontal edge gaps, and the vertical edge gaps; and
a power supply or microprocessor for driving the electronic display placed at the rear of the cooling back pan within the sealed rear compartment, wherein the power supply or microprocessor is in conductive thermal communication with the cooling back pan;
wherein the fan is substantially sealed within the rear compartment such that ambient air is not permitted to contact the power supply or microprocessor.
