Heat Exchanger for an Electronic Display

摘要

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.

主权项

1. A cooling system for an electronic image assembly having a front and rear portion, the system comprising:
an open loop of ambient air flowing along the rear portion of the electronic image assembly; a closed loop of circulating gas travelling around the electronic image assembly; a heat exchanger in gaseous communication with the open loop of ambient air as well as the closed loop of circulating gas; one or more fans positioned to force circulating gas through the heat exchanger; and one or more fans positioned to force ambient gas through the heat exchanger.
