Ion wind in the service of cooling chips
Researchers at Pardew University in the North American state of Indiana have developed a promising way to improve the efficiency of computer cooling systems. The experimental device created by them is an “ion wind” generator and, according to scientists, is capable of cooling chips 2-2.5 times better than regular coolers.
But in fact, the device does not replace the fans used for cooling, but harmoniously complements them. The fact is that simple coolers cannot ensure the movement of air molecules as close as possible to the surface of the cooled chip. According to the developers, the phenomenon of their invention is that it enhances the flow of air exactly where it is most needed.
The experimental cooling device consists of a positively charged anode located 10 millimeters from the array of negatively charged cathodes. When air flows through the device, the cathodes discharge electrons in front of the anodes. The electrons are mixed with air molecules, and the ions formed in the process are thrown back to the cathodes. In the end, this creates the so-called "ion wind", which increases the flow of air cooling the chip.
Although the technology is more than promising at the moment, scientists are working on improving it. In particular, on reducing the distance between the anodes and cathodes from millimeters to microns. When this succeeds, prototypes of ion wind generator devices can be brought to the market.
