Apple Exploring Liquid Notebook Cooling Systems for Cooler Laps

I'd rather my computer not make it look like I have wet myself, thank you.

Hey, why not boil water and surf the web at the same time!
I would buy a macbook that made tea/coffee so fast!

If they can't get watercooling on desktops right, apple shouldn't consider doing it on a portable!

But will it have Firewire and a Matte screen? ;-)

Deleted.

ummm can you say G5 cooler fluid leak?

what else apple didn't filed patent for?.... a time machine... no they have time machine... maybe a worm hole...

"Oh crap!..my laptop's water broke!"

Sounds good to me. I am glad that they recognize potential future hurdles and are already hard at work on them. Can't wait for Snow Leopard and Open CL etc.

Toshiba had a better patent

Toshiba designed (and I think actually built) a laptop that didn't need the pump for the heat pipe; it was pure convection; water heats up, transfers through the hinge, cools on the back of the screen and falls back down a separate pipe. Wouldn't work if it wasn't oriented with the screen above the keyboard, but that is not exactly the design case. (OK, maybe on a plane or train...)

If you can get enough of a temperature gradient, you might even be able to pull off a phase change with minimal external pumping energy, which would let it work without gravity.

I'd like to see liquid nitrogen cooled laptops

I remember reading of firms trying this YEARS ago - how can Apple be filing a patent for it now?

Jeez! About time!!!

I will not buy a water cooled anything - remember the PowerMac G5's?

To be honest, the heat is crazy that comes off of my Macbook Pro! If you're wearing shorts your legs will be burnt in no time with that thing.

I'm still rocking a liquid cooled dual 2.5 G5. It's a great machine, got faster with leopard, and center of my home recording studio. Maybe I just got lucky with one that has good plumbing.

Seconded. Apparently they didn't learn their lesson. Though, what choice do they have? Consumers and developers "demand" that clock speeds climb, which means increased heat.

that's actually a pretty neat idea. The back of the display is a large surface with usually nothing touching it, so you got great airflow.

Might get tricky getting watter through the hinges...
How about a copper heatpipe? And LCDs usually don't like hot temperatures...

does this mean quiet laptops???

very exciting if this is where they're headed.

Better get rid of your car then.

I guess they didn't learn their lesson from the leaking G5's. Personally I don't want anything water-cooled sitting in my lap.

that would open the door for more powerful laptops...and a moist lap.

I'd certainly consider it but...

considering that the only time I've had a serious laptop failure was after spending an hour walking to work with my PowerBook in my backpack at -46, I'd want to know what effects this sort of system might have on the sensitivity of the system to cold.

I just wish component makers would just make components that generate less heat, I know, its a crazy idea... I love my Nvidia chips, but even with a computer or laptop idling - its warm.

They are doing just that. When they do a die shrink of a component, it generally will produce less heat.

They then use the fact that it produces less heat to crank up the clock speeds more, bringing the temperatures up to where they were before the die shrink, but at a faster speed.

And if you look at video cards, mid range video cards use less energy and produce less heat than high end video cards from 3-4 years ago while offering better or equal performance. It's a combination of better architectural improvements (ie, better methods at processing the data) and the die shrinking.



Manufacturers can definitely "make" components that use less energy by lowering the voltage and clock speed (if you lower the voltage but not the clock speed, the component will become unstable). You can do it with any CPU and video card (well, they generally make the video cards so you can't adjust the voltage, but you can still lower the clock speeds which will lower temperatures). The problem is, when you do this, the component won't be as fast.

horrible idea, horrible.

does anyone have links to people who have tried it.
