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.
Claims20
An assembly for cooling an electronic image assembly placed within a housing, the assembly comprising:
- an ambient gas pathway positioned within the housing;
- a circulating gas pathway positioned within the housing;
- a heat exchanger placed within the ambient gas and circulating gas pathways;
- and
- an ambient gas fan positioned within the heat exchanger to force ambient gas through the heat exchanger.
An assembly for cooling an electronic image assembly within a housing, the assembly comprising:
- an ambient gas pathway;
- a circulating gas pathway encircling the electronic image assembly;
- a first portion of a heat exchanger placed within the ambient gas pathway;
- a second portion of a heat exchanger placed within the ambient gas pathway;
- and
- an ambient gas fan positioned between the first and second portions of the heat exchanger.
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;
- an ambient gas pathway connecting between the inlet aperture and exit aperture;
- a heat exchanger in gaseous communication with the ambient gas pathway, the heat exchanger comprising two portions;
- a first fan placed between the two portions of the heat exchanger to force ambient gas through the heat exchanger;
- and
- a second fan positioned to force circulating gas through the channel and at least one portion of the heat exchanger.
