Heat Exchanger for an Electronic Display
First Claim
1. A cooling system for an electronic image assembly having a front and rear portion, the system comprising:
- a front display surface spaced apart from the front portion of the electronic image assembly;
a channel defined by the space between the front display surface and the front portion of the electronic image assembly;
a heat exchanger in gaseous communication with the channel, the heat exchanger having first and second gas pathways, where the first gas pathway is in gaseous communication with the channel;
a first fan assembly positioned so as to force circulating gas through the channel and the first gas pathway; and
a second fan assembly positioned so as to force ambient gas through the second gas pathway.

Abstract
A cooling assembly for an electronic image assembly having an open and closed gaseous loop. A closed gaseous loop allows circulating gas to travel across the front surface of an image assembly and through a heat exchanger. An open loop allows ambient gas to pass through the heat exchanger and extract heat from the circulating gas. An optional additional open loop may be used to cool the back portion of the image assembly (optionally a backlight). Ribs may be placed within the optional additional open loop to facilitate the heat transfer to the ambient gas. The cooling assembly can be used with any type of electronic assembly for producing an image.

12. An electronic display comprising:
-
an electronic image assembly having a front and rear portion; a front display surface spaced apart from the front portion of the electronic image assembly; a channel defined by the space between the front display surface and the front portion of the electronic image assembly; a heat exchanger having first and second gas pathways, where the first pathway is in gaseous communication with the channel; a housing containing the electronic image assembly, front display surface, channel, and heat exchanger, where the housing, channel, and first gas pathway of the heat exchanger define a closed gaseous loop; a first fan assembly placed within the closed gaseous loop; an inlet and exhaust aperture in the housing, where the inlet aperture, second pathway of the heat exchanger, and exhaust aperture define an open gaseous loop; and a second fan assembly placed within the open gaseous loop. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. An electronic image assembly comprising:
-
a liquid crystal display (LCD) having an LED backlight; a transparent front display surface spaced apart from the LCD; a channel defined by the space between the front display surface and the LCD; a heat exchanger having first and second gas pathways, where the first pathway is in gaseous communication with the channel; a first fan positioned so as to force circulating gas through the channel and the first gas pathway; a first surface in thermal communication with the LED backlight; a second surface spaced apart from the first surface; a second channel defined by the space between the first and second surfaces; and a second fan positioned so as to force ambient gas through the second gas pathway of the heat exchanger and through the second channel.
