It would appear that a group of mechanical engineering professors at Stanford University have hit the jackpot in more ways than one. Their company, Cooligy Inc., has developed a passive, closed-loop cooling system for high-speed computer chips that's been tested and approved by Apple, Intel, and AMD (plus the Defense Department).
Here's how it works according to Macworld UK, and notice the ingenious electro-kinetic pump at its heart:
The new system absorbs and dissipates heat from the chip's hot spots. It collects heat using a thin layer of micro-machined silicon that sits on top of the microprocessor. "A very dense area of Micro-Channels etched into the silicon enables fluid to circulate through the heat collector and efficiently absorb and take away heat," the company explains. A tiny solid-state Electro-Kinetic pump circulates fluid through the cooling system and to a "heat radiator", which transfers the heat to air. The solution makes no noise, has no moving parts, and is reliable in the long-term, the company said.
Comments: The second part of the jackpot due for professors Ken Goodson, Tom Kenny, and Juan Santiago will be knowing that their efforts will make it possible for all of us to enjoy the benefits of the next generation of microprocessors. Faster laptops will be one of the first results, no doubt.
