System for cooling an electronic image assembly with a heat exchanger having internal fans
First Claim
1. An assembly for cooling an electronic image assembly within a housing having an inlet aperture for ambient gas, exit aperture for ambient gas, and internal cavity for circulating gas, the assembly comprising:
- a first portion of a heat exchanger which accepts ambient gas from the inlet aperture;
a second portion of a heat exchanger which accepts ambient gas from the first portion;
a first fan positioned between the first and second portions which pulls ambient gas through the first portion and pushes ambient gas through the second portion; and
a second fan which forces circulating gas through the internal cavity and at least one of the heat exchanger portions.

Abstract
A system for cooling an electronic image assembly using a heat exchanger with an internal fan assembly. Circulating gas may also be used to cool a front portion of the electronic image assembly or any other internal cavity of the electronic display housing. The circulating gas may be drawn through a heat exchanger so that heat may be transferred to an ambient gas. The heat exchanger may have an internal fan assembly for drawing ambient air through the heat exchanger and exhausting it out of the display housing. The heat exchanger may be divided into two portions so that the fan assembly is placed between the two portions.

16. An electronic display assembly comprising:
-
a housing having an inlet aperture and exit aperture for ambient gas; an electronic image assembly within the housing; a transparent front plate in front of the electronic image assembly, the space between the transparent front plate and the electronic image assembly defining a channel; a heat exchanger in gaseous communication with the channel, the heat exchanger comprising two portions, each portion having first and second gas pathways, where the first gas pathways are in gaseous communication with the inlet and exit apertures and the second gas pathways are in gaseous communication with the channel; a first fan assembly placed between the two portions of the heat exchanger to force ambient gas through the first gas pathways; and a second fan assembly positioned to force gas through the channel and the second gas pathways. - View Dependent Claims (17, 18, 19, 20)
