General Electric has developed a miniature cooling system. Originally developed for jet aircraft engines, it is about to arrive in a reduced version in Ultrabooks.
The final device is named Dual Piezoelectric Cooling Jets. It is composed of two ceramic plates which contract and expand successively thanks to an electric voltage which is subjected to them. Inspired by human lungs, this bellows movement generates an air flow which significantly increases heat transfer. In the open position, the device receives the hot air. By closing, it releases only fresh air. Thanks to this operation, the Dual Piezoelectric Cooling Jets is able to process 0.2 cubic meters of air per minute.
Another advantage is that it is only 4 mm thick, half the size of a small fan. A gain in space therefore which is also accompanied by a gain in autonomy, “Up to 30 minutes more”, according to the engineers. Still in the prototype state, the Dual Piezoelectric Cooling Jets should enter mass production in 2013 to be integrated into Ultrabooks and other tablets in 2014.
