The fanless spinning heatsink: more efficient and immune to dust
SourceI give you the Air Bearing Heat Exchanger [PDF]. Developed by Jeff Koplow, a researcher at the US government’s Sandia National Laboratories, the new heatsink (which has also been dubbed the “Sandia Cooler”) basically resembles a big, metal fan. The cooler consists of a static metal baseplate, which is connected to the CPU, GPU, or other hot object, and a finned, rotating heat exchanger that are cushioned by a thin (0.001-inch) layer of air. As the metal blades spin, centrifugal force kicks up the air and throws it up and outwards, much like an impeller, creating a cooling effect.
The fanless spinning heatsink: your questions answered by the inventor
SourceAfter we covered the fanless, dust and detritus-immune heat exchanger last week, we were inundated with questions about the new technology. How does it work? Does it really use a thin layer of air to transfer heat — and if so, how can that possibly be better than copper or thermal grease? Is it really immune to dust, or are you just being hyperbolic? Are you sure that it can actually save 7% of annual electricity consumption in the US?
