Introduction: It is interesting how different parts of a value chain speak differently, sometimes wildly differently, about a product or feature but they may use the exact same words. For example, both the consumer and the thermal engineer want the device to have “cool” features. Wireless charging is one such hardware feature [1]. Wireless charging was included in over … [Read more...]
Book Review of Electronics Cooling (2016)
by MP Divakar, PhD, Stack Design Automation Technical Editor, Electronics Cooling Online Electronics cooling engineers and designers are used to one constant in their professional lives: change. Most of it (as far as problem solving is concerned) is change for the worse… and is challenging! The heat flux keeps increasing, the geometries keep shrinking, the available solution … [Read more...]
Tech Brief: Commercially-available Thermally Enhanced Polymer Composite Materials Characteristics
Peter Rodgers, Editor Valérie Eveloy, The Petroleum Institute Introduction The development, characterization, and implementation of polymer composite materials for the thermal management of electronic equipment has recently began to attract attention [1,2]. The enhanced thermal conductivity, low density, low cost, ease of manufacture and corrosion resistance of polymer … [Read more...]
Combination of Two Insulators Could Enable More Efficient Heat Management
(July 28, 2016) Recently, “researchers at the University of Utah and the University of Minnesota have discovered that when two oxide compounds—strontium titanate (STO) and neodymium titanate (NTO)—are joined together, they make an extraordinary conductive material that could vastly improve power transistors,” according to Spectrum.IEEE.org. By themselves, each material … [Read more...]
Fan-less Modular 600W PSU Announced
Excelsys has recently announced the development of its CoolX600, a fan-less modular 600W power supply that is 215 x 115 x 40mm (8.5 x 4.5inch x 1U). CoolX600 can be populated with up to four ‘CoolMod’ output modules, providing up to four isolated DC outputs ranging from 2.5V to 58V. Higher input surge protection is 4kV line-to-PE for harsh environments, and there is reverse … [Read more...]
