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.
Claims20
-20. (canceled)
A heat exchanger for an electronic display having an open loop for ambient gas and a closed loop for circulating gas, the heat exchanger comprising:
- a plurality of plates comprised of corrugated plastic, arranged in an alternating pattern where a plate that is in gaseous communication with ambient gas is sandwiched between a pair of plates that are in gaseous communication with the circulating gas.
A heat exchanger for an electronic display having an open loop for ambient gas and a closed loop for circulating gas, the heat exchanger comprising:
- a plurality of plates having channels travelling in a first direction and oriented parallel to one another with a gap between each pair of plates, where each plate has an entrance side;
- and
- a strip of material placed within each gap and oriented perpendicular to the channels.
A heat exchanger for an electronic display having an open loop for ambient gas and a closed loop for circulating gas, the heat exchanger comprising:
- a plurality of plates having channels which are in gaseous communication with either the ambient gas or the circulating gas;
- and
- a pair of strips of material placed between each plate and oriented perpendicular to the channels, where a gap is defined between the strips and the adjacent plates, such that the gap accepts ambient gas if the channels are accepting circulating gas and vice versa.
