thought or  Some Really Cool Speakers Researchers at Georgia Tech have come up with a novel localized cooling device that promises to replace the ubiquitous CPU fan and other such applications. The SynJet uses vibrating diaphragms (essentially speakers), driven at 100 to 200 Hz, to force puffs of air out through openings in its cavities, and through cooling fins. Efficiency and effectiveness are improved by using less current, making less noise and lower vibration levels. The resulting puffs of air churn through the thermal boundary layer that forms normally when a steady airflow is applied. Innovative Fluidics has purchased a license for commercial exploitation, and plans to sell the devices in 2005. | ||||||
