New Heat-Sink Design Promises Cooler Lasers

Facebook X LinkedIn Email
COLUMBUS, Ohio, Oct. 18 -- Researchers at Ohio State University announced they have developed a heat sink for lasers and other microelectronic devices that is more efficient than current designs. The scientists reported that in simulations, a microelectronic circuit employing the new heat sink design heated up only about one-third as much as a circuit using a standard heat sink. The OSU team, which was comprised of Kambiz Vafai, professor of mechanical engineering, and graduate student Lu Zhu, improved upon a conventional micro-channel heat sink design. This early design operated much like...Read full article
