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

Liquid cooling or 'thermal spreader': check out the S7 edge heat pipe insides (video)
Back when the Galaxy S7 and S7 edge were announced last week, the first teardowns of the handsets revealed some sort of a heat pipe running around the processor area, presumably a tiny liquid cooling system, like the ones on Sony's high-end Xperias, or the Lumia 950. Samsung then confirmed that the phones do indeed feature this, when talking about its new Game Launcher setup: "the cooling system in these phones, with a very thin thermal spreader, keeps devices cool, so gamers can focus on winning."

There you have it, we definitely don't have liquid nitrogen running in your phone, being pumped by tiny goblins to swoosh elegantly around the CPU in clouds of frozen mist. What we do have, however, is flatter copper piping with a minuscule amount of liquid, often just water, that evaporates when it hits the CPU area, takes the heat away with the gas it forms, and condenses back into liquid when it runs further down the pipe, like on the scheme here:


Samsung itself calls it simply a "thermal spreader," instead of liquid cooling, though technically we likely do have a drop of liquid in there, and it's made on a very, very compact scale. Want to see how it actually looks like from the inside? Well, the video below comes to the rescue, from about 4:30 in, and you also get to see the other set of tiny goblins - the ones that are trying to hold the camera steady when you shoot video, or the so-called optical image stabilization. It's fascinating, check it out.

Make it all out of copper

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

Oh sorry That would be great in terms of thermals But copper isn't as strong as magnesium alloy, might be heavier too

better than nexus and sony liquid cooling.exynos 8890 throttles less than 5% cpu score 2195-2036 gpu onscreen 27-25fps.SD version gpu throttles lessential than 810 29fps-23fps

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?

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