Researchers at the National University of Singapore have developed a new two-phase technique they say is up to 50 percent more effective in cooling electronic systems compared to current cooling technology. Led by Lee Poh Seng, Ph.D., of the Department of Mechanical Engineering at NUS, the team combined microgap and stepped fin microchannel heat sinks to create a two-phase … [Read more...]
Magnetic Nanoparticles Prevent Hotspots in Cooling Systems
An international team comprised of researchers at MIT and in Australia has discovered a way to enhance heat transfer using magnetic fields, a method they say could prevent hotspots that can lead to system failures. The new system, which relies on tiny particles of magnetite, a form of iron oxide, is the result of several years of research on nanofluids—nanoparticles dissolved … [Read more...]
Heat Sink Watch Helps Wearer Manage Body Temperature
Four engineering students at MIT have developed a thermoelectric bracelet designed to help wearers maintain a comfortable body temperature. Resembling a wristwatch, the invention, known as Wristify, monitors air and skin temperature and sends pulses of hot or cold waveforms to the wrist when needed to help the wearer maintain thermal comfort. A custom copper-alloy-based heat … [Read more...]
Defense Contractors to Develop Next-Gen Military Electronics Thermal Management
U.S. Air Force officials have awarded multimillion dollar contracts to BAE Systems and Boeing Co. as part of DARPA’s Intrachip/Interchip Enhanced Cooling Applications (ICECool Applications) program. The ICECool program seeks to develop advanced electronics cooling techniques for high-performance embedded computer (HPEC) and RF monolithic microwave integrated circuit (MMIC) … [Read more...]
New Surfaces Ease Dissipation of Extreme Heat
A new method of cooling extremely hot surfaces more effectively from researchers at MIT could benefit industrial equipment and electronic devices. Considered by many to be a quieter, more efficient way of removing heat compared to traditional air cooling methods, liquid cooling is commonly used in a number of applications such as internal combustion engines in vehicles and … [Read more...]
