Liquid cooling or 'thermal spreader': check out the S7 edge heat pipe insides (video)

I don't see any liquid, I call BS on that.

I'd say heat pipe since its narrow, vapor chamber are usually wider
But they are the same thing, just difference in width

Or vapor pipe :)) From outside it looks like solid but inside is filled with copper fibers and a another kind of metal aluminum or something. It woud be expensive to be solid copper I guess

either way without having a fan to move medium over condenser its not going to dump much of the heat and turn back to liquid, i wonder what freon is being used

I create vapour chambers in my car all the time... I vape. I vote. I lol.

It has pressurized liquid/vapour, which would evaporate when cut open due to pressurize difference
The Sony heat pipe would have had a different liquid/vapour and different pressurize
Maybe lower pressurize since the 810 gets hotter, it doesn't need as high pressurize to reduce its boiling point
So not all the liquid in the Sony heat pipe vapourised
All the 950 XL's heat pipe also vapourised when Jerry cut it

They guy was like, "Let me put it all back in and it will be as good as new". I bet that copper pipe he ripped will not mend on it's own!
It's amazing to see how people have managed to fit so many things in one small device! I won't be surprised to see a fridge in there. :D

Optimized for Better Performance
With a more than 30 percent faster CPU speed, a more than 60 percent faster GPU speed and 4GB of RAM, the Galaxy S7 and S7 edge have the power needed to satisfy the most demanding players, in the most intense games. With a very thin thermal spreader cooling system, these phones can run fast and cool.

How Samsung plans to keep the Galaxy S7 cool
Samsung hopes to address any overheating issues with the Galaxy
As hardware makers cram more power into smartphones, the heat produced by the CPU and GPU becomes more of a problem. Samsung hopes to address this issue with the Galaxy S7 and S7 Edge by using liquid cooling.
"Whoa, liquid cooling?" I hear you scream at your screens. "Doesn't that mean pipes and radiators and water and so on?"
The sort of liquid cooling we're talking about here isn't like the liquid cooling systems that performance gamers use to cool their PCs. Instead, what we're talking about here is a closed-loop heat pipe technology.
There's still a liquid involved, but only a drop, and this is safely held inside metal tubes that are made of copper or aluminum. The liquid, which in this case is probably water or ethylene glycol, passes over an evaporator where it is exposed to the heat of the CPU of GPU. Here it is turned into a gas, and this vapor then makes its way along tiny tubes to a diffusion plate or radiator, where the heat is given off and the vapor turns back into a liquid and then makes its way back to the evaporator.
Note that the diffusion plate doesn't feature a fan or such, and there are no pumps inside the heat pipe moving the liquid and vapor about. It's a purely passive device, and its purpose is to take the heat from the CPU and GPU and dissipate it over a larger area, preventing the formation of hot-spots, and hopefully putting an end to overheating (which was a problem that Qualcomm had with the Snapdragon 810).
All of this sounds big and clumsy, but it isn't. Fujitsu has a heat pipe system designed specifically for smartphones where the pipes are only 0.1mm thick, and the evaporator and diffusion plates are only 0.6mm and 1.0mm thick, respectively.
And the Samsung Galaxy S7 isn't the first smartphone to feature liquid cooling. Microsoft's Lumia 950 and Lumia 950xl both use liquid cooling. Sony's use of the technology goes further back, to the Xperia X2, which was released in March of 2014.
Why use liquid cooling? It's probably being used for a number of reasons. First, Qualcomm had problems with the Snapdragon 810 overheating, a problem that resulted in Samsung passing up on the chip for the Galaxy S6 and S6 Edge. The liquid cooling would certainly help to prevent this issue from happening again.
Another reason is that smartphone makers are using more and more glass in their smartphones. Because glass is a poor conductor of heat, hot spots can form on the device, and even if the back is metal, these hot spots can make the device uncomfortable to hold when it's running demanding apps.
Also, let's not forget that "liquid cooled" looks good on the sales material. I have little doubt that by this time next year, every major smartphone manufacturer (with the exception of Apple) will be touting liquid cooling as a feature on high-end devices.

iPhone arena is a Samsung hater site And f**ker site
( Apple's cowards). This site and its writers are apple-biased.
The exaggeration in this post. It's not really an issue. Read the source: ZDNet .What part of "you are a complete brainless f**king idiot" do you not understand?

This is actual technology used in spaceships. Get reckted m8

It was pressurized liquid, which uses evaporative cooling to transfer the heat more efficiently than just copper

Rad. I was referring to the whole phone. Imagine shiny copper looks
19. vincelongman (Posts: 3979; Member since: 10 Feb 2013)
That would be great in terms of thermals
But copper isn't as strong as magnesium alloy, might be heavier too

Saying Sony and Nexus liquid cooler is worse while comparing different cpus? (810 is a dragon)

If it wasnt for liquids, why make it hollow? If it was just using the copper as passive heat spreading material, why not make it solid? Please answer that iPA?

Rumors: Xiaomi Mi5 Users have overheating issues.

the cheaper version wont have that problem since it have underclocked SD820

Actual research from the hacks that write at this site is a stretch.
