No liquid in Samsung Galaxy S7 edge’s liquid cooling as shown in a teardown

After the numerous reviews, comparisons, analyses, and durability tests, it's time to open the Galaxy S7. A recent Galaxy S7 edge teardown by JerryRigEverything, as by an XDA member revealed that the latest two premium flagship smartphones used heat pipe liquid cooling but unfortunately don't contain any visible liquid. This is very much different from what was previously seen on a Sony Xperia Z5 Premium. It's not exactly a problem because as the phone heats up, the pipe works by wicking vapor as explained by Matthew Brack in his post.

Before we all get confused, there were only very little liquid as noted by one commenter on the forum. Whatever little "liquid" was there, it absorbed the heat and quickly became vapor which then traveled along the pipe where it's usually cooled and condensed (condensated). Heat is then released. Liquid cooling means liquid circulating, thanks to a mechanical pump going to a heatsink. The latter is then cooled by cool air running over it. Heat is usually absorbed or removed by a fan. That's liquid cooling as explained by one commenter but Samsung has yet to explain exactly how it is used or done on the Galaxy S7 edge.

Mattew Brack noted how Samsung described the phone would come with "liquid cooling" so he and Zack Nelson (JerryRigEverything himself), or actually just about anyone would have high expectations. One example is the Z5 Premium whose liquid cooling contains actual liquid. This Samsung Galaxy S7 edge, however, doesn't show any liquid.

This particular teardown already started a discussion. It's interesting to know if and when Samsung will post an official explanation, as well as, how the rest of the Netizens will respond and offer their own opinions. Leave it to the experts to explain how this liquid cooling works. Or you may delight yourself in sharing your own throughts in the comment section below.

    The same thing happened with the Lumia 950 xl. Experts say that just because they say it is liquid cooling doesn’t mean there has to be litres of water. They could have used ammonia or something like that.

    You didn’t even bother to research the liquid cooling system on the phone before writing this…

    “”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).”
