Thinner, lower powered laptops,perhaps even thinner cooling solutions for GPUS and the like?!
I'm in!
How does it avoid getting clogged with dust? As long as air is passing through it, dust will enter and eventually stick to something. Or do they mean that cleaning out the dust will be easier?
The internal pressure is pretty high and so is the speed at which air is spat out, not to mention it's flapping about 100 times per second over a 0.5mm distance (it's going to shake stuff off). There's not the same deterioration in performance either unless it was so clogged it couldn't close, but then the idea is the pressure should increase and blow away any dust.
The title has piezo misspelt!
I'm probably being unspeakably dumb, but is there any kind of valve arrangement to ensure that there's a flow of air generated - rather than merely the same "packet" of air being drawn in and then spat back out again? (which I guess wouldn't cool very well)
Still don't see what the attraction of "thin" is beyond a certain point. E.g. as other have said, rather than a 4mm thick phone they'd prefer an 8mm thick one and 4mm extra battery. Likewise with laptops.
Actually, I find your question valid.I imagine they could pair them and reverse the polarity on the other one? That should, in theory, be enough to have air move around a bit more. Of course, even if they didn't do that, hotter air would still rise and displacement ventilation would still occur.
Er, Alistair, could you add a link to an article explaining how these things work? Or is the idea to ask each other in the comments and get back theories as to what might be going on? Questions about the dust, the air flow and why the 4cm component in the diagram is mounted perpendicular to the board. ;o)
No worries, I found one. ;-)
The video - by GE, not Joe ReviewerSite - is very informative, apart from Mr Marketing at the end.

Just realised this thread is over 9 months old, so thank you devBunnry for reviving it with that useful post.
(and I see piezo is still mis-spelled)
