Joe Boswell, Chris Smoot, Elliot Short, Nate Francis Introduction In this study, lightweight two-phase heat sinks embedded with the Oscillating Heat Pipe (OHP) technology are developed for the thermal management of military circuit card assemblies (CCA). OHP-embedded heat sinks efficiently transport heat generated by CCA centrally located components to the assembly’s … [Read more...]
Metal Organic Frameworks Applied in Layers Could Signal Cooling Revolution
Researchers at Germany’s Fraunhofer Institute of Solar Energy Systems have developed highly-porous metal organic frameworks (MOFs) that can be applied in a thin layer to efficiently absorb large quantities of water vapor. MOFs, as determined by research published in RSC Advances, are three-dimensional porous structures consisting of metallic clusters and organic linkers adept … [Read more...]
Superconducting Refrigerator Cools via Tunneling Cascade
Researchers from Italy and France have proposed a new design for a superconducting refrigerator that uses a series of steps to more effectively cool objects down to temperatures near absolute zero. Conventional superconducting refrigerators rely a array of superconductors (S), normal metals (N) and tunnel barriers (I) that are arranged in a symmetric configuration (SINIS or … [Read more...]
New Device to Cool Chips at the Micro-Scale
Researchers at the University of California, Berkeley and the University of California, San Diego have developed a novel evaporator structure that can be integrated directly into electronics to cool chips with micro-sized components. “The idea behind this project is to use liquid, in this case de-ionized water, to absorb the heat produced by any kind of device, then evaporate … [Read more...]
Thermal Adhesive Tape Reduces PCB Production Time
Universal Science, a provider of thermal management solutions, has introduced a reflowable, thermally conductive adhesive tape designed for application during PCB manufacturing. Bondline 1000-Reflow can be laminated directly to PCBs prior to processing, enabling the PCBs to be finished/ supplied with a thermally conductive, mechanical fixing tape pre-applied and thus reducing … [Read more...]
