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...]
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...]
Magnetically-Stimulated Flow Patterns Could Boost Heat Transfer
Magnetically-stimulated fluid flow patterns may offer a new method for handling difficult heat transfer problems by overcoming natural convection limits, according to new research from scientists at Sandia National Laboratories. Convection cooling, which refers to the transfer of heat between two places by the movement of fluids, is often forced in many modern cooling systems … [Read more...]
Magnetic Refrigeration Could Replace Compressor Systems
Researchers working in GE labs have used special magnetic materials to generate temperatures cold enough to freeze water in a breakthrough that could find its way into commercial refrigerators by the end of the decade. (Video: General Electric). Researchers at General Electric have unveiled a new refrigerant system utilizing special magnetic materials that could be up to 20 … [Read more...]
Researchers Eye Passive Cooling System for Microelectronics
Researchers at San Diego State University in California are examining an alternative to traditional heat pipes they say could help increase cooling efficiency in laptops and other portable electronic devices. Known as pulsating or oscillating heat pipes, the system may offer a heat transfer capacity up to 100 times better than conventional heat pipes, says assistant professor … [Read more...]
