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...]
Case Study: Thermal Design and Analysis of a Combat-Ready Electronics Unit
INTRODUCTION Militaries continue to expand their use of electronics in harsh environments while preserving an absolute minimal risk of failure. In this regard, effort spent early in the design process on concept development, parametric and trade-off studies, and simulation-driven design can yield amplified benefits in terms of product performance and reliability, reduced … [Read more...]
Cooling Circuits with Nanochimneys in Carbon Nanotubes
The extraordinary properties of Graphene are well known, and in the context of electronics thermal management and reliability, it is about 200 times stronger than the strongest steel and conducts heat and electricity very efficiently. Both graphene and carbon nanotubes consist of six-atom rings, which create the well-known hexagonal Honeycomb structure, and both excel at the … [Read more...]
Thermal Facts & Fairy Tales: 7 years of college down the drain…
...might as well join the Peace Corps… - John "Bluto" Blutarsky1 I would hazard a guess that the majority of people bothering to read an article on electronics cooling likely work in the electronics industry. Moreover, it is probably a pretty good bet that a lot of them have actually taken a class on heat transfer at some point. Since most of us eventually graduated, it … [Read more...]
92ML™ StaCool™ Thermally Enhanced PCB Materials Manage Heat in Power Electronics Applications
Scott D. Kennedy Senior Product Manager Rogers Corp Power Electronics Design Trends Power electronics and associated thermal design is an essential early stage of many product development efforts, especially with growing demand for vehicular and industrial applications. Current trends to increase vehicular driver assistance features, reduce the carbon … [Read more...]
