As devices become smaller and slimmer, the heat generated in their LSI circuits becomes larger, and the speed of hard disks and optical disks increases. As a result, the heat sink and cooling fan inside such devices must be made larger, and in addition, higher fan speeds produce more noise. For these reasons, finding a way to overcome the heat generated in digital devices has been a major problem. Accordingly, we have developed a silent liquid-cooling system to overcome this problem. This system is already being employed in laptop PCs, and is now opening up vast new realms for tomorrow's digital devices. Until now, the backside area of the LCD panel of laptop PCs has never been utilized for cooling purposes. But by installing an aluminum alloy radiator panel over the entire back side of the LCD, we have improved the efficiency of the heat radiation while saving space. In this unprecedented challenge of employing a liquid-cooling system on compact digital devices, we have made full use of the latest technology to prevent liquid leakage (a major concern) and improved reliability with virtually maintenance-free operation.
