Fan-less cooling solution for laptops up to 40W launched
We are still waiting for CES to find out who the partners are.
Device uses movement of ions to generate airflow without any moving parts like in iPads and MacBook Air.
You're viewing a single thread.
Ionic acceleration of air needs high voltages and the air gets ionized (the reason people recommend against vacuuming a PC). I'm surprised that it works at all in close proximity to sensible tech.
Edit: right, low static pressure, meaning: lower voltages. But still not low.
They use a grounded faraday cage around it. Video on it where he touched on that https://youtu.be/fyai_kUYhLs
Can't watch the video rn, anything about the dust problem?
He just mentions they have a solution but it’s patented so they wouldn’t talk about it. Take that as you will of course
Strange, patented means it should be findable on the USPTO system, diagrams and all. And yet..
Either there's a filter or the plates will cycle charging up to repeal the dust partials.
the reason people recommend against vacuuming a PC
A regular vacuum isn't doing anything with ions or high voltages. Moving air can generate potentially harmful static electricity, but usually the reason people recommend against vacuuming a PC is because if you spin the fans doing that, the motors inside turn into generators and drive current back into your PC parts that could damage them.
Moving air can generate potentially harmful static
Well, and what do you think creates that static electricity? Ionization.
Feeding back electricity, that's why motors usually have a diode or something.
The difference between a vacuum and this fanless cooling device is that a vacuum happens to generate a small amount of static, and usually has grounding wires in the hose to prevent it shocking things, while this fanless device is intentionally ionizing as much air as possible to get it to move.
Exactly, that's why i'm wondering how it is save.
