'Ion Wind' CPU cooling solution from Purdue University


Effective cooling solutions have been the albatross around the neck of CPU manufacturing companies since the early days of computing. Now, researchers at Purdue University, in a study funded by Intel, have demonstrated a cooling technique that increases the heat dissipating capacity of CPUs by as much as 250%.

The details of the technology are elucidated at Physorg.com and in the article at Ars Technica. The technology relies on the creation of ionic winds between closely placed electrodes. When a voltage is applied across the electrodes, the electrons collide with air molecules, creating ionic winds in the small spaces.

Conventional air-cooling solutions suffer from the "no-slip" effect, where the air molecules near a surface cling on while the farther placed molecules flow away. This does not cause cooling to occur rapidly. Hence, the ionic winds created at the miniature scale can radically improve the cooling processes. The researchers are hoping for a breakthrough in a year's time, during which CPU makers can happily hunt for more power within micro-packages.

Liquid nitrogen is very cold but has a low heat capacity and boils easily but If you used 0 degree water or a little above that it has a high heat capacity so maybe you could use your refrigeration to keep the circulating water near its ice point.

I would have to see the sientific journal to make a more in depth determination, but this sounds very intresting, I have been looking into trying to produce a Liquid Nitrogen pump and stand alone housing unit that would somehow bold to the processor or processor and mother board, with out having the processor expire from the stress put on it from being subjected to -198 c tempetures. Usually the processors will expire in a very short amount of time. I am looking to build , or 'think' of new solutions to possibly use liquid nitrogen as a long term and stable cooling solution for PC's.

Ionic winds seems great!!! But they should check out the effect on system components and also on environment before applying it commercially...

While for the average user cooling is not an issue this is still huge because of the limitations imposed in our hardware due to heating, and gamers everywhere will also appreciate this...if it is a technology that can me implemented commercially... AIT Tapes
