- vtnerd, on 12/02/2008, -10/+47An aluminum heatsink? Please explain why they deserve a patent for a idea that is both obvious and not novel.
Better title: Apple is a patent troll. - cawpin, on 12/02/2008, -6/+34Wonderful, they won't screw up a liquid cooling system....oh wait. Any pissed off G5 owners out there?
- sonicEd, on 12/03/2008, -2/+23Why is it so difficult for these articles to link to the patent app?

- raydeen, on 12/03/2008, -0/+9Dear Apple,
Proper ventilation and proper use of thermal paste. Look into it. Cooling problem solved. - illDecree, on 12/03/2008, -3/+12i wonder if they can use Apple Juice for the liquid?
- ChromaVita, on 12/03/2008, -1/+10Nope, only Starbucks lowfat soy espresso.
- rdwinder, on 12/03/2008, -8/+16what a cool idea!
- oboshoe, on 12/03/2008, -0/+8TSA says its fine, but since it contains more than 6 ounces of liquid, you'll have to buy your Macbook in the airport at one of the vendors.
- inactive, on 12/03/2008, -6/+14Can we see some statistics and sources for #2?
- bakingoven, on 12/03/2008, -0/+7heavier than copper or aluminum?
- GeorgeStone2, on 12/03/2008, -8/+15It's not the number of patents. It's the % of stolen ideas held within them.
- MeadeEM, on 12/03/2008, -0/+7Unfortunately, they are probably not patenting the aluminum, but the entire process
- pixeldust, on 12/03/2008, -0/+7You didn't even read the patent did you? It's not patenting an aluminum heatsink it's patenting an entire water cooled laptop processes.
- inactive, on 12/03/2008, -2/+9Tell me about it, every time I try to lift a bottle of water I pull a muscle.
- kazolar, on 12/03/2008, -0/+6I call BS on this, I've taken laptops apart, and heat pipes are just that, coper "HOLLOW" heat pipes, similar ones that are inside the PS3, and on many modern passively cooled PCs, and motherboards. I need some proof that a there are laptops that actually use some liquid to transfer heat.Also, liquid expands as it heats up, and contracts when it cools, a sealed heat pipe is in essence pressurized, and I would image there would be some major problems since the as the liquid cools and heats up -- especially in a confined space as a small heat pipe.
- MacParrot, on 12/03/2008, -2/+8It usually does...as does Windows or Linux except when it doesn't. What's your point?
- MacParrot, on 12/03/2008, -0/+6Maybe you shouldn't masterbate with your laptop on your lap?
- level32, on 12/03/2008, -1/+7that's what she said
- slvrbullet87, on 12/03/2008, -0/+5Great until you drop the thing 6 inches and a tube cracks. then you leak liquids all over your motherboard
- fezzasus, on 12/03/2008, -5/+9They ARN'T. It's called defensive patenting, you investigate an idea and patent it to prevent others from exploring the same area. It happens all the time in business.
Patents are not an accurate way of predicting products. - krnldmp, on 12/03/2008, -0/+4In my opinion they are wrongly approaching this. Is it a goddam crime to wait until one more step in processor technology allows today's speeds at 1/2 the energy loss? Do we really have to make laptops 75% battery and cooling system instead?
- GeorgeStone2, on 12/03/2008, -3/+6Haha, that's exactly what I thought when I read the title.
- boomerang42, on 12/03/2008, -2/+5Sounds like an interesting idea, but I'm more than a bit skeptical.
We'll just have to see how Apple plays this one out. As an owner of a 2007 MBP, I must say I'm frustrated with the excessive heat problems of the laptop, so if my next laptop had liquid cooling, I'd probably accept it with open arms. Lets just hope this doesn't fall on it's face like so many other Apple "inventions". - inactive, on 12/03/2008, -2/+5Macbooks run hot - really hot. Hopefully this will remedy that.
- PigGeneral, on 12/03/2008, -0/+3Unfortunately I have yet to get my computer working via winding gear using a spring for storing kinetic energy. I think the fact it is about 5 orders of magnitude less power than just the hard disk needs to spin up might have something to do with it...
- jr93087, on 12/03/2008, -0/+3good thing that figure really gives one an idea of how the system works.....
- javaroast, on 12/03/2008, -0/+3You weren't ever going to use it anyway so no real loss.
- UselessTrivia, on 12/03/2008, -0/+3PigGeneral is correct, i suppose I misspoke when I said "water". Technically it's just a liquid. It's not just a straight hollow tube...that would be pointless as a hollow tube won't conduct heat as well as a solid one.
The heat pipe is also not 100% filled, and the tube is rated to handle the few PSI of pressure exerted at max temp. Think of a thermometer. It's a partially filled tube so that the expanding mercury or alcohol has somewhere to go without busting the glass. - PigGeneral, on 12/03/2008, -0/+2I'm just stating the power difference to run a single magnet on a minesweeper to beep, vs a fully featured laptop to power up, is immense. Your concept is sound, however it is similar to attempting to take a rowboat across the Pacific because it works in a lake.
- fallingdamage, on 12/03/2008, -0/+2given apples epic failure rate on MacBooks' log boards because of video processor overheating, maybe this will be the a viable answer.
im getting tired of ordering $300-$400+ logic boards for my customers who bought apple "because they didnt think they would have to deal with this crap with Apple" - FordSVT1, on 12/03/2008, -0/+2Does this mean my wife's Mac Book won't burn my legs in the future?
You can cook eggs on those, they're insanely hot. - InorganicMatter, on 12/03/2008, -1/+3While liquid cooling a notebook is a unique idea, I can't see it ending well. Anyone use desktop water cooling systems? Those things do require regular maintenance, and are a pain/disastrous when they malfunction.
- vtnerd, on 12/03/2008, -1/+3I did read it.
They put an aluminum plate on the back of the laptop, put in a pump and move coolant around.
Patents need to be nonobvious, novel and useful. It's certainly useful, but it's definitely not novel or nonobvious. I'm not saying it's a bad idea, but I am saying that they don't deserve a patent for a system which has existed for quite some time.
Water cooling on a laptop sounds awesome and I'd love for it to not be uncomfortably warm in my lap. I just don't want to pay Apple tax for a feature that does not deserve a patent. - PigGeneral, on 12/03/2008, -1/+3There is a fluid inside those heat pipes. They use a fluid with a low boiling point to allow it to carry heat to the heat sink. Cools off, condenses back to liquid, flows back to the heat source. The side mounted ones you see in a laptop have nifty inner workings. When the liquid medium boils, it acts to pump the remaining liquid onto the heat source.
- schmitey, on 12/03/2008, -0/+2I agree that's not efficient. But 3rd world country minesweepers for example have pendulums of some sort that produce enough energy by the back and forth motion to be powered. Something like that might help extend and charge the battery on the go. I make no claims to be an engineer, I'm just saying it'd be awesome if it worked.
- cawpin, on 12/03/2008, -0/+2No, we're talking the towers. They offered liquid cooling and a bunch of them took a dump last year.
- Etchii, on 12/03/2008, -1/+3I've had two liquid cooled setups, the first one had a buildup of.."sludge"? that clogged the pump and caused a hardware failure. Luckily I only had it hooked to the graphics card at the time and didn't loose both the card and the cpu.
My rebuild had a much larger cooling tower and I took better care of the system with more regular liquid changes and flushes.
It works phenominally when there are no issues, but keep an eye on things...when it goes down it goes down fast. - TheUngod, on 12/03/2008, -0/+2So...you're trying to defend Apple from being a patent troll by arguing Microsoft applies for more. Your argument is poor, because as a larger company, Microsoft SHOULD be applying for more.
- CoreyTamas, on 12/03/2008, -0/+2thanatosys: Thanks for digging that up. I was *just* looking for that info when I saw your post.
- BossKey, on 12/03/2008, -0/+2@drcreek:
1 guy, 1 cpu - TheUngod, on 12/03/2008, -1/+3Microsoft applies for more patents because Microsoft is a larger company that produces more things.
- OwdenBowden, on 12/03/2008, -5/+6It is code name: APPLE JUICE
- clockdist, on 12/03/2008, -0/+2"That's hot..."
- fezzasus, on 12/03/2008, -0/+2The volume of water used will be very small, there are already components in your laptop that contain liquids; capacitors and heat pipes (when running).
The water doesn't pose a problem during normal operation, outside of normal operation, damage extensive enough to cause a leak will most likely irreparably damage other components too. The point being that it isn't any worse than a normal cooling setup. - fezzasus, on 12/03/2008, -0/+2Completely unusable at this temperature, the ferro or para magnetic metals required for liquid metal cooling arn't available until they are heated above 1500 degrees C, obviously destroying any component of the laptop that must be cooled. Turning away from metals, you could use liquid oxygen, but this is a poor conductor and is explosive.
