Rittal’s TopTherm fan-and-filter units are a synthesis of radial and axial fan technologies that deliver a combination of high pressure stability and large volume air flows. Unique to this fan technology, the air outlet direction is diagonal to the outside rather than in the fan's axial direction. This approach favors an even distribution of air in the enclosure or housing, and … [Read more...]
Industry Analyst Names Firm a ‘Cool Vendor’
iWatt Inc., a developer of energy-efficient digital power supply control integrated circuits (ICs), recently was recognized in Gartner’s “Cool Vendors in Semiconductors” report. The company advances “digital power management” with its patented Adaptive Digital Control technology. iWatt uses digital algorithms to replace traditional analog control solutions, delivering size, … [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...]
Thermoelectricity: Turning Temperature Differences Directly into Electricity
The fundamental problem in creating efficient thermoelectric materials is that they need to be good at conducting electricity, but not at conducting thermal energy, say Massachusetts Institute of Technology (MIT) researchers. That way, one side can get hot while the other gets cold, instead of the material quickly equalizing the temperature. But in most materials, electrical … [Read more...]
Nearly Back to Business as Usual
I’ve not posted for a while, which is rather remiss of me. I underestimated the response we would get to our Heatsink 201 webinar, which I gather was our most popular ever, and the number of questions that people would ask. I had around 120 questions, which after removing duplicates and those to do with logistics ended up at around 80, so it took a while to answer them all. … [Read more...]
