[Electronics-Cooling] Micro-Vacuum Technology May Cool Future Smartphone Processors

post #1 of 6

Researchers from the University of Michigan, Massachusetts Institute of Technology (MIT) and Honeywell International, Inc. have developed microscale vacuum pumps that could lead to tiny, more efficient cooling systems for faster processors in smartphones.

Developed as part of DARPA’s Chip-Scale Vacuum Micro Pumps (CSVMP) program, the new microscale vacuum pumps are intended for use in highly sensitive gas analyzers for the detection of chemical and biological attacks, laser-cooled chip-scale atomic clocks and microscale vacuum tubes.

I was looking for updates on this other DARPA funded cooling project and came across this. Apparently air-cooling is still of some significant focus.

Air cooling will always be the simplest way to go when you have an atmosphere around you. Now, in space... Interesting that we can get pumps down to that scale though. I'd think that mechanical devices would have limits to how far they can shrink and still be effective and that moving air on this scale would burst the valves from the pressure.

Wow that's awesome. Does anyone know how it works? Is it a physical reaction or a chemical reaction that makes it pump?

Well, there's several different designs, all of which seem to be more of a proof of concept than anything else. They all appear mechanical in nature, though the ones pictured all seem to go about achieving a vacuum in different ways.

But I don't really know what you mean by chemical vs. physical reaction. Were you thinking of those Dyson bladeless fans?

that isn't actually bladeless

Dangit I guess they got me then. I figured it was one of these.
