A team led by Dr Ole Martin Løvvik of Oslo University’s Centre for Materials Science and Nanotechnology in Norway has found a way of making cheap thermoelectric materials that could harvest waste heat from a range of scenarios. However, attempts to bring the technology into the mainstream, in order to harvest waste heat from industrial and everyday scenarios, have been limited … [Read more...]
Compact Linear Laser Diode Driver Supports Fiber-Coupled Lasers
Wavelength Electronics’ PLD-CH Series is now available in a 12.5 A model. This new driver supports fiber-coupled lasers used in applications such as medical, dental, micro-machining, material processing, semiconductor inspection, and imaging. The PLD-CH Series offers single-supply low voltage operation from +5 V DC, which minimizes heat dissipation. For applications that … [Read more...]
Thermally Conductive Grease Used for Solar Industry
A product that is proving useful to the solar industry is LORD Corporation’s TC-501 Thermally Conductive Grease. This solvent-free, silicone thermal interface material (TIM) is designed to replace greases used as TIMs between the heat spreader and the heat sink (commonly known as TIM2). It provides high thermal conductivity and low thermal resistance for applications where … [Read more...]
Heat Conducting Graphene Could Cool Electronics
Multiple layers of graphene show strong heat conducting properties that can be harnessed in removing dissipated heat from electronic devices, a team of scientists from the University of California reported in a recently published paper in the journal Nature Materials. Having previously shown that graphene — a two-dimensional layer of carbon atoms packed in a honeycomb structure … [Read more...]
Exploring the Limits of Air Cooling
Introduction Heat from electronic devices is an integral part of information processing, not a nuisance that can someday be eliminated. This is a physical principle that is independent of the device of information processing. However, when viewed in the historical perspective, the severity of heat problems has not monotonically increased. It came to the fore some time ago, … [Read more...]
