Applied Nanotech’s new passive thermal management material, CarbAl™, is a carbon-based material with a unique combination of low density, high thermal diffusivity, and low coefficient of thermal expansion. CarbAl™ has a density of 1.75 g/cm3 compared to 2.7 g/cm3 for aluminum and 8.9 g/cm3 for copper. While copper has a slightly higher thermal conductivity than CarbAl™, 390 … [Read more...]

Researchers Find Spider Silk Conducts Heat as Well as Metals
Xinwei Wang and his research team at Iowa State University found that spider silks - particularly the draglines that anchor webs in place - conduct heat better than most materials, including silicon, aluminum and pure iron. Spider silk also conducts heat 1,000 times better than woven silkworm silk and 800 times better than other organic tissues. Spider silk conducts heat at … [Read more...]
Data Center Technology Controls Temp by Moving Software Workloads
Facebook is exploring a technology that controls temperatures in the data center by automatically moving software workloads among servers according to the air pressure on either side of each machine. The system uses a load balancer to shift tasks among servers based on their particular “cooling needs,” which are related to air pressure in the data center. The idea is to keep … [Read more...]
Ideas Sought for Better Electronics Cooling Technology for Helicopters
A helicopter corporation is sponsoring a contest, asking entrepreneurs and companies that are willing to establish a spinoff at a new innovation center in Stamford to propose technology concepts that could be used on helicopters. Chris Van Buiten, vice president of Sikorsky Innovations, gave an example of a better electronics cooling technology, which could reduce the number … [Read more...]
