Low-emissivity (Low-E) films are not new –they represent a mature technology in which a metal-oxide coated surface emits low levels of radiant thermal energy. Low-E films are widely used on window glasses in energy-efficient buildings. Low-E materials include metals like Aluminum foil which has a thermal emissivity /absorptance of 0.03 which means that it reflects 97 percent of … [Read more...]
Liquid Silicone Rubber (LSR) Widely Available
Liquid Silicone Rubber, with its low compression set, fast cure cycles, great stability and ability to resist extreme temperatures of heat and cold makes it ideally suitable for the production of parts where high quality is a must. Unlike most thermoplastic elastomers (TPRs and TPEs), LSR remains flexible and elastic down to -70o F and retains its properties up to 450o F. In … [Read more...]
Cooling the DARPA Space Surveillance Telescope (SST)
by MP Divakar, PhD, Stack Design Automation Technical Editor, Electronics Cooling With many nations joining the race of sending satellites out to space, the number of orbiting space debris is increasing year after year. This NASA portal estimates the number of space junk as over 500,000 orbiting earth at speeds of 17,500mph or higher. Most of the half-million plus objects … [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...]
Heat Sinks Improved with 3D Printing
(July 18, 2016) The complimenting research done by Oak Ridge National Laboratory and the University of Tennessee Knoxville has found a way to improve the heat dissipation in electronics using 3D printing. According to 3DPrint.com, “[Oak Ridge] researchers are showing that 3D printed aluminum may be a more viable source for conducting heat than traditional materials. And at … [Read more...]
