Washington, April 1: As an important step towards the development of highly effective micro-coolers, an Indian-origin researcher at the University of Twente has created a cooler for electronic products which is about three times smaller than conventional coolers, yet has a higher cooling output.

Srinivas Vanapalli says that he created this cooler while exploring the possibilities for the extreme cooling of electronic components at a chip level, because electronics work better under cold conditions.

He says that these make use of the oscillating compression and expansion of a working gas.

According to him, two factors proved to be critical in the miniaturisation of these coolers — the cycle frequency had to be increased as well as the average pressure of the gas in the system.

The researcher says that both factors are necessary to ensure that the miniaturised system has sufficient cooling capacity.

Vanapalli’s new cooler with a frequency of 120 Hz is approximately three times smaller than conventional (50 Hz) coolers, yet can cool down the smaller dimensions much faster.

The cooler was realised in close cooperation with the ‘National Institute of Standard and Technology’ in Boulder, US.

Thales Cryogenics in Eindhoven has expressed a serious interest in this development, which is directly applicable to their products. (ANI)
