Double sided display assembly with bi-directional flow through a common, partitioned heat exchanger

A display assembly comprising:

• a structural framework;
• side assemblies, each connected to the structural framework and comprising a cover, an electronic display, and one or more channels;
• a heat exchanger positioned between the side assemblies and within the structural framework;
• and
• a closed loop airflow pathway comprising:
• a first portion comprising at least one of the one or more channels of a first one of the side assemblies;
• a second portion extending between the first portion and a third portion of the closed loop airflow pathway, said second portion comprising a first portion of the heat exchanger, distal from the first one of the side assemblies;
• the third portion extending between the second portion and a fourth portion of the closed loop airflow pathway, said third portion comprising at least one of the one or more channels of a second one of the side assemblies;
• the fourth portion extending to the first portion of the closed loop airflow pathway and comprising a second portion of the heat exchanger, distal from the second one of the side assemblies;
• and
• one or more fans, which when activated, move circulating gas through the closed loop airflow pathway, including through the first portion of the heat exchanger in a first direction and through the second portion of the heat exchanger in a second direction opposing the first direction.

An electronic displays apparatus, comprising:

• two individual electronic displays configured in a back-to-back arrangement in a housing;
• a shared heat exchanger positioned between the two displays, and within the housing;
• at least one fan in the first of the two displays and at least another fan in the second of the two displays;
• and
• a pathway for cooling air to circulate inside the displays and the housing, said pathway defined to comprise the route cooling air is enabled to travel through said apparatus in the space between a cover glass and display panel on the first of the two displays, then through a first portion of the heat exchanger in a first direction, exiting the heat exchanger and circulating between a cover glass and the display panel of the second of the two displays, then through a second portion of the heat exchanger in a second direction opposite of said first direction, then back to the first of the two displays, such that during operation of said fans the cooling air continues in a continuous cooling air stream in the pathway.
