Improved Cooling for Computers

Researchers at the cheapest cialis in uk US Department of Energy's Sandia National Laboratory have developed a new method for cooling microprocessors that is more effective and requires less energy than present air cooling methods. The Air Bearing Heat Exchanger technology, which has been dubbed the "Sandia Cooler," offers a solution to the "thermal brick wall" which has been limiting microprocessor speed.

Cooling is tramadol 50mg tab addictions usually limited by the heat exchange taking place through the stationary air film that is found on all materials. The Sandia Cooler improves works by rotating the cooling fins to achieve a ten-fold reduction in the boundary layer of motionless air on the buy viagra online and get prescription surface of no order prescription viagra the heat sink which increases heat transfer. Instead of having stationary heat sink fans with air being blown across them with a fan, the heat sink itself spins, which leads to increased heat transfer efficiency.

While the Sandia Cooler is initially being investigated for computer cooling, if it is possible to effectively scale the technology, it could also have applications for building cooling and air conditioning. "If Air Bearing Heat Exchanger technology proves amenable to size scaling, it has the potential to decrease overall electrical power consumption in the U.S. by more than seven percent," according to the inventor, Jeff Koplow.

" has the potential to decrease overall electrical power consumption in the U.S. by more than seven percent..." - This probably will not reduce power consumption for computers. If anything, it will make people desire more powerful (and therefor more power consuming) CPUs.

It would be interesting to see how this technology could be applied to cooling in power plants, residential heat pumps and A/Cs, as well as automobile radiators.
Improves Heat Pump Efficiency

Besides computers, the research project investigated heat pump (HVAC) applications. The power consumption reduction was from improved AC efficiency, not computers. Supposedly there is a ~30% decrease in heat exchanger efficiency from newly manufactured AC units to 4-8 years of service life. Also, efficiency is limited by noise. The air-bearing impeller can also be used to move air through ducts for the inside AC coils.

Jeff you are right-- improved heat sinks will enable even more bloated inefficient power hungry computation. The best solution (besides scrapping bloatware) is a multi-core processor where one CPU is slow but super-low power, and the other cores can be powered off when not required. Most computers are >99% idle most of the time but burn almost the cialis 20 same power as when 10% idle.

@Jeff and Carl - please, this is not 1997. For personal computers, only gamers need more "power hungry computation". For servers in datacenters, often the limit to scaling is power availability from the grid and/or thermal limits from HVAC infrastructure. Better cooling helps with both of these problems: more computation for less total watts going to click here buy online prescription cialis the building or large server room. This can mean more computers, or lower overall cost, your choice. This is called progress. Multi-core with asymmetric core performance only makes sense for consumer equipment. For server installations of any size worth discussing virtualization is buy cialis in canada no prescription much better: have fewer servers utilized as much as possible. This is one of many reasons VM has taken off in the last 5 years.
