XPMS 1530 cooling assemby

New here so Hello to everyone.
Does anyone know if the copper tubes around the fan assembly contain any liquid?
My machine is dead with suspicion of a spillage but no signs to where it could have entered.There are a few odd patches but a larger and heavier stain where the copper tube is near the bottom case.Thanks for looking.

Laptop cooling assemblies do not contain any liquids. Could you include a picture so that we can perhaps identify what these stains are?

 

Uh, yes they do?

What else does a heatpipe contain then? Jello?

Agree with Polarix - those DO contain liquids.

 

Here's a pic of the fan assy.

I've never heard of computer heat pipes containing liquid of any kind. I found an article on Wikipedia, but it doesn't directly say that this method is used in laptops. Your post doesn't clarify anything and is quite useless; but I'll believe it when I see it.

 

Well, I think I would go with Bog... Because as far as I know, I think this liquid cooling units or such were only recently being proposed for laptop' and there was no indication that the current systems shipped with heat pipes containing liquids inside (particularly the M1530)... there is also some active research going on in some leading labs in the US n Japan for getting in liquid cooling into laptops.. but again, I may be wrong, but for now, I would go with what what Bog says.....

 

Heat pipes do contain liquid, though not very much (few grams) Its usually a liquid with a very high latent heat of vaporisation (Ie. takes a lot of heat to turn into gas) It'd sort of be like the liquid you'd see if you sprayed an aerosol can (eg. lynx) on a piece of paper.

If theres liquid or a stain inside the lappie its unlikely its anything to do with the pipes.

Firstly the gas/liquid inside is under high pressure so the heatpipes are high pressure, sealed vessels - you'd have to bend or give them a banging to damage them.

Secondly if they did fail (crack or something) the liquid//gas would evaporate quickly and there'd be no traces left behind.

If the machine died due to overheating (unlikely - don't the chips shut down when temps go too high?) then it could have been something to do with them. Otherwise something must have been spilt on it.

 

i see a crack on the heat assembly right before entering the place where the northbrige is ( bottom left ), call dell and tell them, it will most likely mean a motherboard and heatsink replacement.

the leak could have created a short on the motherboard, thus rendering the computer useless.

 

Thanks for your inputs .Well we seem to have a split in opinion at the moment.
The label on the fan reads Aavid 34.4W105.001 and the one on the pipe is CN-0XR216-68282.Does anyone know a way of finding the answer from these part numbers?
The end of the pipe in the left side of the picture looks pitted and not as smooth as the rest.If there is a leak i would guess it's from that spot.

Lol. My post was a lot more useful than your post which contained false information.

You apparently didn't read anything in the wikipedia article because it blatantly states in the first paragraph under Structure, Design, and Construction:

Want to try me again?

 

Did you read the other post detailing the "kind of *fluid* or *liquid* present", in any case?

Also as far as I can see from your quote, its just says heat pipes.. doesnt specifically say "laptop heatpipes or heatpipes in laptops or notebook computers".. infact they talk only about some bigger applications...

Further, from the wiki,

> it doesn't say its already being used... and afaik, as I said before, they are researching now and still not in commercial use (afaik!!!)

Further, I am sure the other explanation for laptop cooling or heatpipes seem more reasonable rather than a heatpipe with a whole lot of liquid flowing inside... (think the other post was from 'yomamas....' nicknamed user)

Anyway...

 

Okay. What else is in the heatpipes in our M1530's then.

 

AFAIK, I think they are just copper heat pipe' leading to the heatsink.... till now, I have never come across anyone anywhere about these heat pipes containing liquid of any kinds... Correct me if I am wrong.

 

Is it so shocking and unacceptable to you that the heat pipes could be hollow? That would allow the fan to effectively suck heat through the heat pipe as one would draw warm air through a straw.

Also, as fonduekid already pointed out, none of your posts have proven anything. Your previous animated picture demonstrated how a liquid-filled heat pipe worked, not that they are used in laptops. Same with the second blurb you posted.

 

Heat pipes ARE hollow sealed tubes. The heatpipes in laptops are the same as in any other application that uses them, just smaller.

Heat pipes do contain liquid and gas (same substance just different state).
They are usually made of an external sealed copper pipe, on the inside attached to the walls of the copper tube there's usually a material that is very good at causing liquid to flow through it by convection.(convection isn't the right term, I just can't remember what the actual one is!)

Like if you put the end of a paper towl in water, the water would eventually rise up through the towl.

The pipe is usually put between a hot and a cold source (like a heatsink and a very hot processor)
In doing so a circut is set up, the liquid near the hot point gets hot and turns into gas creating pressure it expands towards the cold end of the pipe where it then gets colder and turns into liquid which then travels back to the hot source via the material on the inside of the pipe and then it repeats.....

This is how they ALL work. Regardless this doesn't really solve the liquid in the laptop problem.

Any chance of a more detailed picture? it might explain things a bit better.

 

you sir are correct
