Danamics - a revolutionary cooling system?!

[C3]

We were informed by our source that Danamics , a Danish
company focused on cooling technologies, is going to
launch a revolutionary cooling system very soon.
The most important fact is that it uses liquid metal to
remove the heat.Therefore Danamic's solution is able
to remove the dissapating heat extremely fast
while offering an amazing cooling performance as well.
he liquid metal is moved by an electromagnetic pump without
moving parts, which makes the pump unhearable.
A reliable source told us it is going to hit the shelves
in Q3 right in time for Intel's Nehalem.So stay tuned!

This sounds like a really good step forward for heatpipe coolers but without any fans on the sink itself, the cooling is only going to be acceptable at best.

Anyone else reminded of Terminator II?

[n-sanity]

Lol liquid metal cooling has been around for quite a while now. I've seen this back in 2005 i believe... Good to see it's finally coming to fruition, but please oh please no thermaltake talk... "dissapating heat extremely fast
while offering an amazing cooling performance" shouldn't be there.

Companies should take notice of Petra's Tech Shop and market like them.

Haha thats exactly what I thought first
Comeback of the T-1000 haha

I'll get excited when I see it. Especially when I see it beat a TRUE while being completely silent.

And how is liquid metal supposed to cool things? Doesn't metal need to be really hot in order to become liquid? How do you get liquid metal at 30C?

[WangChung]

Yeah I remember this from WAY back. If I remember correctly it's a Gallium/Tin mix in a cooling loop. Wonder if I can still find the old company info...

Depends on the metal. For example copper won't melt until a bit over +1050 C whereas mercury will melt at -40 C or so.

they stick a really big thermometer to your cpu, it doesnt cool for , but at least you know the temps your computer died

[Micutzu]

Mercury is liquid at normal temps, and also Gallium is melting at 29C. There are also a few radioactive metals that melt at 30-40C.

[cegras]

I think if you mix alloys you can get liquid metal. Just like how tin/lead solder will melt really easily.

Anywho, liquid metal probably has the best heat conductance. Not sure about capacity though .. water is probably the champion there.

FWIW I'm pretty sure hydrogren is the champion, but there are also alot of polar organics that are much higher than water as well and won't blow up so easily :p.

Yeah, ok. But mercury is expensive afaik. And not completely safe. Any known metal that has those properties, is safe and is cheap?

Safety is the key word. The toxicity of this should it break is important, because you know some screwball is going to pop the thing open to see what's inside. As well, Mercury and toxic metals can be enormously expensive to get rid of...

[alexio]

A gallium and indium alloy can be liquid at room temperature. Both are non-toxic in the sense that you could drink a few droplets of this alloy without a serious health risk. If you add tin to this you can make alloys that stay liquid all the way to -20C or even a little bit lower

If I remember correctly the reason liquid metal coolers have repeatedly been hyped then dropped before launch was the tendency for the heat to build up in the transport medium (liquid metal). I'd be interested to see if this has been resolved in these new models, but to be honest I think vapour chambers and heat pipes will still be preferable for small coolers.

[Frank M]

Umm no. Heatpipes work with a different principle: using capillary effect
to lead condensated liquid to the heat source, where the liquid is
evaporated into the vapour chamber and then on the cold side of the
heatpipe, it condensates again into the capillary material, loop closed.

Lol liquid metal cooling has been around for quite a while now. I've seen this back in 2005 i believe...

Lol liquid metal cooling has been around for quite a while now. Mercury was
used as coolant for some early nuclear reactors and nuclear submarines in
the ussr...

Ditto.
I think heatpipes still have some room to grow - just look at Xigmatek's
direct touch heatpipes, 6 vs 8mm heatpipes, or Sapphire's "vapour chamber",
which is also a heatpipe basically, just with bigger size and flat. Base
contact, fin contact, number and diameter of heatpipes - it still has some
more in it.

[nn_step]

it isn't revolutionary by any stretch, the reason we don't use things like this is because they typically cost as much as phase but only perform as well as standard heatsinks

Liquid Metal Cooling from quite a few years ago... ...Electro-magnetic pump 'n all...

[largon]

I bet a cookie we will not see a retail product come out of this.

[Serra]

Well that website's pretty much completely useless to go to, isn't it? The only thing the thing says is that they're a "a leading manufacturer of liquid metal based cooling solutions... since 2005". Yet if you do a Google search on them and the words "liquid metal", you get nada. Even a search just on their name quickly spirals into irrelevancy (mostly people who can't spell "dynamics").

As other posters have said, it has long been known that liquid metal is both possible to use and indeed has been used in a variety of VGA coolers... but the issues of cost and quality are large. So in regards to this, I'll remain skeptical.


There was a member of these forums who a set of CPU coolers pulled from some military computers who might be able to add some fun info. iirc, it was basically a water loop, but used a liquid gallium/tin alloy. Here's the link, for anyone whose interested that may not have been around at the time:

Liquid metal, sounds good

[twilyth]

It doesn't have to be completely metal to work though does it? Couldn't it be metal particles in a suspension. This would be relatively safe and cheap. Moving the metal particles with a magnetic field should move the liquid medium along with it. In fact, if they're going to use an electromagnetic pump, would the main metal have to be iron?

I just wonder how much of a pressure increase there is from room temperature to say 70C. Unless the liquid is completely non-volatile up to that temp, there's got to be some increase. If so and if it's not extremely well made, you'll eventually get some stress fractures and then you can kiss your mobo and cpu goodbye.

[Lestat]

correct me if i am wrong here bt wouldn't there be some gas that is emitted from the mercury as its heated???

what are they doing with those emissions ?

and the pressure build up also,,

I'm quite sure that this is supposed to be a closed loop.
