Jet Engine Technology Will Keep Electronic Devices Cool

Scientists at GE's global research labs have adapted technology that improves air flow through jet engine compressors for a super-thin cooling device that could lead to new generation of thinner, quieter, and more powerful tablets and laptops. At the heart of the new technology are two ceramic plates that expand and contract when electricity is applied to them. Their bellows-like movement generates high-velocity airflow, which disturbs the boundary layer over a hot component and dramatically increases heat transfer. The new thermal management component is called Dual Piezoelectric Cooling Jets (DCJ) and is just 3 millimeters thick. While 50 percent smaller than current cooling units, the new component adds 30 minutes of battery life to current devices.
