Freeze your chip, get a faster computer

London, April 2 (IANS) Extreme cold conditions enable electronics to work better and with less thermal noise, according to Srinivas Vanapalli, a Dutch researcher of Indian origin. Vanapalli has explored the possibilities of cooling components at the chip level, to temperatures 150 degrees Celsius below zero, which also boosts its speed and reliability, ScienceDaily reported.

Vanapalli, of the University of Twente, has constructed a proof-of-principle cooler, which cools more effectively than conventional ones and holds promising commercial applications.

He focussed on miniaturising regenerative coolers, helped by two factors: the cycle frequency had to be increased as well as the average pressure of the gas in the system. Both are necessary in ensuring that the miniaturised system has sufficient cooling capacity.

For example Vanapalli’s 120 Hertz cooler was approximately thrice as small as conventional (50 Hertz) coolers, but with a higher cooling output that cooled down the smaller dimensions much faster.

Vanapalli carried out a significant part of his research on even smaller and consequently even higher frequency coolers. This mainly concerned the balance between heat exchange and pressure drop in the micro-channels of the cooler.

Vanapalli carried out his work in tandem with National Institute of Standard and Technology in Boulder, US.
