POSTER: computer news   ||   GENERAL ELECTRIC CAME UP WITH A COOLER OF 4 MM THICKNESS	DATE:2012-12-15
Trying to create a tablet device with more powerful processor or make laptop even thinner, designers are faced with the problem of electronic components cooling.  Due to limited space in the case a full cooler is extremely difficult, other methods of dealing with the excess heat energy is not as effective.  Ironically, the solution was found in the aircraft industry. General Electric Engineers were able to adapt a dual piezoelectric injector (Dual Piezoelectric Cooling Jets or DCJ), which was used to cool the jet engines.  The product with the dimensions of 40 x 40 x 4 mm consumes less power compared to traditional fans . DCJ consists of four paired together piezoceramic plates, which are deformed by the electricity, simulating the process of breathing.  Absorption and emission of air occurs with a frequency greater than 100 Hz, so the generated flow is sufficient to cool chips. CPU Core i7-3667U, installed in the demo laptop was heated to a temperature of 38 degrees Celsius in a simple load, with a heavy load cooler was unable to cope.  In addition, the prototype is powered by USB port and noticeably vibrates during operation.  Noise produced by DCJ, does not exceed 30 dBA. However, after a series of adaptations and upgrades DCJ may be registered not only in ultrathin laptops, but even in Tablet PC.   Related Products :
