Researchers at Tel Aviv University have developed superconducting wires using fibers made of single crystals of sapphire to be used in high powered cables. Factoring in temperature requirements, each tiny wire can carry approximately 40 times more electricity than a copper wire of the same size. They have the potential to revolutionize energy transfer. High power … [Read more...]
Bristly Particles Could Manage Heat Flow in Electronics
A well-known method of making heat sinks for electronic devices is a process called sintering, in which powdered metal is formed into a desired shape and then heated in a vacuum to bind the particles together. In a recent experiment, students at MIT led by Kripa Varanasi, d’Arbeloff Assistant Professor of Mechanical Engineering, tried sintering copper particles in air and … [Read more...]
LED Driver IC Market Buoyed by Growth in Backlights
A new report from Strategies Unlimited finds that the market for LED driver ICs is sizeable at $2 billion in 2010, buoyed by strong growth in LED backlights in mobile phones, TVs, and monitors. Innovations promise to help meet aggressive price and performance targets necessary to expand further the market for LED lighting, particularly in replacement bulbs. These innovations … [Read more...]
All Detailed Thermal IC Package Models are Wrong… Probably
'Rubbish In -> Rubbish Out' is a well accepted fact in the world of simulation. Regardless of the technical capabilities of your thermal simulation tool, the accuracy of prediction will always be tightly coupled to the accuracy of the input data. The most accurate thermal IC package model is a so called 'detailed' model where all the internal construction is represented … [Read more...]
Underfloor Electric Heating. Part III – Penny wise, pound foolish.
It would only have cost me an extra £170, a small extra compared to the cost of the rest of the build, but I decided against laying thermal insulation boards directly under the underfloor electric heating mats. Surely better to leak some of the heat down to heat the 100mm thick concrete screed which would maintain its heat through those cold winter weeks, giving thermal support … [Read more...]
