German scientists have successfully fabricated compact microchips able to tolerate temperatures up to 300°C in an achievement that could have significant implications for the geothermal and oil production industries. Drill bits and borehole probes employed in the geothermal industry are fitted with a range of sensors and control mechanisms in order to record and analyze … [Read more...]
Polymer-Based Thermal Interface Material Cools Devices at 200°C
Scientists have developed a new polymer-based thermal interface material (TIM) capable of conducing heat 20 times better than conventional polymer. Reliable in temperatures of up to 200°C, the modified material can be fabricated on heat sinks and heat spreaders and adheres well to components in servers, LEDs and mobile devices. “Thermal management schemes can get more … [Read more...]
Researchers Pinpoint Heat Movement in Nanostructures
Researchers at Cornell University have developed a new method of precisely measuring the subtle movement of heat in nanostructures. Heat flows at the nanoscale differently than at larger scales, the researchers say, and understanding how certain surfaces affect the transport of heat at the phonon level could have implications in everything from thermoelectric materials to … [Read more...]
Liquid Cooling System to Cut Data Center Cooling Costs
An associate professor of mechanical engineering at the University of Wisconsin-Madison has developed a liquid cooling system he says is safer than water cooling and could cut cooling costs of data centers by up to 90 percent. Data centers are growing at a rate of seven to 10 percent per year in the U.S., and associated cooling costs are on the rise as well, says associate … [Read more...]
Graphene Improves Copper Film Thermal Conductivity
The placement of a single atomic plane of graphene on the surface of a copper film can significantly increase the film’s thermal conductivity, making the hybrid material ideal for more demanding thermal management applications, according to new research from scientists at the University of Manchester, UK and the University of California-Riverside, U.S. The phenomenon was … [Read more...]
