Samsung hardware engineer explain liquid cooling - Samsung Galaxy S7 Edge Guides, News, & Discussion

Since the tear down video doesn't show any liquid in the vapor tube, a Samsung engineer gave the explanation on a Chinese biggest social network weibo. He said there are 0.02 gram purified water in the vacuumed tube, due to such a small volume and the vacuum space, the liquid will vaporized immediately once we cut the tube. He said even there is not that much water inside, the result is actually pretty good. Here is the link http://m.weibo.cn/1651911632/394890...WEIBO_SECOND_PROFILE_WEIBO_-_3948908579071957 .

Yeah, this was known in the PC enthusiast world for a long time since we've had heatpipes in heatsinks for a long time already.
A mountain was made out of a non-issue here.

IIRC this kind of technology is used on spaceships.

No Liquid in Vapor/Condensation Tube

I hope this is a flawed device and not an indicator of the way Samsung does business.
The video also explains it, it's not a flaw.

I've watched it a few times and it doesn't. I've got a pretty good grasp of physics so I think it's safe to say there's no liquid in there. I'll draw it out for you. Any vapor in the chamber would have to be 1) heated or not a liquid at room temp, 2) not mitigate the heat in gaseous state. Liquid/Vapor chambers work when the liquid mitigates the heat (heating it up to a gas state) and then runs up the tube to the cooler area of the heatsink (welcome to entropy) and then recondenses. This is how they work. Without any liquid at room temperature it very obviously is not a liquid cooled chamber. If it's not a flaw then Samsung is basically a company willing to blatantly lie to increase their sales.
Easy fellas! You're both right. As the video explains, the s7 has a "heat pipe" rather than liquid cooling. From my perspective, as long as it does its job, I couldn't care less, but it is interesting that sammy represented it as liquid whereas it is not....

It seems to be working perfectly fine for most who have the device in hand except for the few reporting overheating during VR. My concern would be the inconsistency in both Samsung's message and the product. For all practical purposes it might not matter.

I'm not experiencing any overheating issues with the S7 edge using Gear VR, and I tried it for hours at a time.
Compared to the S6 edge, MAJOR IMPROVEMENT!!!!

:highfive: Excellent. If all the phones function that way it's a moot point.
Is it possible all of the liquid is actually contained within the copper fibers and thus not visible? I would assume there's not very much as it would expand when It became a gas. Just throwing out ideas. By contained I mean, essentially stuck to.
The samsung engineer in China already explained it, there is 0.02 g water or cooling liquid inside and when you cut the pipe, they already vaporized.
As long as the phone doesn't overheat, who cares?

Curious if this turns out to be overheating throttling or just poor software and RAM management:

Guessing the latter. 820 is suppose to run cooler, heat pipe, more RAM than the other android phones.

Where did you find this info?
So I'm guessing that people would rather have notable amounts of water/liquid sealed inside of a $800+. In the even an excessive shock causing the tubing to fail and in turn fry internal component's. To each their own, but I'm comfortable with what the component is capable of doing for what it is......... My .2 cents.

Dude...it's literally two posts above you....
I'm not too sure what people are expecting. There is very very little water inside. I get the impression that some people are expecting water to gush out like a tap.

How good is the water resistance?

Hey guys
I really want to take my xzp into swimming pool and capture some under water photos. But I saw some videos on YouTube where people have water damaged the phones after minimal use in pool.
Is it safe to take under water pics? I'm afraid because of the open charging port and the speakers.
Well it's a difficult question, it's a little bit risky IMO. If you have to do it, better have someone recording you, if the phone gets water damaged you will have a proof for Sony to use for warranty.
I know that Sony has stated that the phone should not be submerged, but IMO this is not an valid argument. The phone should be IP68 waterproof, and if you will not submerge more than 1,5m the warranty should cover the damage, but the video proof will be essential.
No, the warranty does not cover the phone being submerged in water. Having someone record you submerging it will not help your case, it will actually do the opposite.
http://support.sonymobile.com/gb/dm/waterproof/
The IP rating of your device was achieved in laboratory conditions in standby mode, so you should not use the device underwater, such as taking pictures. Do not use the device to take photos while performing any type of activity underwater, including diving or snorkeling.

Ah yes, I missed that part and just saw the responses above, pushing any buttons under water may case you problems arguably if it was on when it went in and the screen could still be used you could take a shot but I'm quite sure Sony would have a field day with it, especially if they find the last photos you took where under water.
Think of the water resistance as a safety net rather than a feature to use.

The warranty should cover what is advertised. What is Sony saying is their game. When they claim the device is IP68, it means it can withstand submerge in water up to 1,5m for 30minutes. You can't really advertise the phone as waterproof and then say you can't use it in water, it's just a big NO for every judge in a normal country. You either can or can not use the phone in water, and while advertisement is one thing, IP rating is an other thing. It MEANS something, and it means the device should be waterproof. I read today an article about Sony being massively sued in US for false advertisement and they gave money to people for it. Sony just wants to save money from too many people using the phone underwater, and it looks like its working.
Man I took it to the pool last weekend and I took so many videos plus photos and super slow motion videos the phone is great under and above water
The phone will heat up if you'll take so many videos even if it's in the water ?, I didn't dive with it so I was using it in 1m depth approx. By the way after you get it out of the water as you know if you have had another Sony waterproof phones the speakers will be very low and not clear for about 4 hours after you dip it in the water, also an advice don't use the charge or the headphones jack right away wait some time and be sure there's no water there before u use them. Overall I had great videos and great experience I love this phone ? and it's camera ?

Show me that false advertising lawsuit, the only one I could find was regarding PS Vita ads which is not what this is about.
The warranty does cover what is advertised... Sony has never advertised the phone as being able to handle underwater photos.
Yes, IP rating is a thing but an IP rating does NOT mean that warranty covers underwater usage... If you put your phone in tap water up to 1.5m depth for a maximum of 30minutes WITHOUT using the phone then sure you could argue that the warranty should cover it. That means, gently putting the phone in tap water with the screen on standby and not moving the phone or the water around the phone and then gently taking it out again.
IEC themselves only classify IPx8 as being protected from accidental submersion, a device with an IP68 rating is not rated for underwater usage. Maybe you should actually do some research before you argue on the internet...

Yea, the phone can handle underwater usage but IF it gets waterdamaged when you are taking underwater photos your warranty won't cover it.
Hi,
I've already read also what happened for other Sony's phone users (like 'aqua' phones that were not aqua-made-for !).
If you use it under water, i advise you not to use hardware buttons, that's for me the main point.
But if you only use screen (unlock, settings, taking photo), there's no problem !
@Zewarxx : i don't know if it's the same for you, but under water, screen is sometimes hard to use : touch-screen thinks some parts are pressed and they're not.
If everyone want to see the issue (for under water usage of phones, not for XZP), just watch water test with IP68 phones, and you'll see that phones thinks that many pressions are made : https://www.youtube.com/watch?v=X0hEMWiqBzs @ 1m14.
Under water, it's not always the case : if you unlock the phone under water, you can take photo/video easily, from my experience (WITOUT HARDWARE BUTTONS).
And yes, no wires after getting out of the water...
I hope it helps.
P.S. You can also buy specific water resistant covers, it's perfect, and you can use your hardware buttons !!! works in the sea, swiming, jumping into water. And it's awsome, colors are jsute perfect (because of the XZP )

IP68 rating means that "The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects. The test depth and/or duration is expected to be greater than the requirements for IPx7, and other environmental effects may be added, such as temperature cycling before immersion.". So if you use the device in that manner, warranty SHOULD cover it.
As for the lawsuit, here ya go:

@cporeaux
Yes man I had some difficulty with the screen while it's wet, but I guess also because it was difficult for the phone to differentiate my fingers and their heat after the get wet so much the shape of them changes ? how ever I used the camera button to take the photos and to stop and start the videos, I even jumped with the phone in the water while the phone dived first then my head and the rest of my body ? GG Sony, and maybe I forgot to mention the water was a bit salty, however I had the Xperia Z and the flaps of that phone were very bad compared to its new brothers once I used it underwater also but because of the flaps were bad and their rubber wear off the water got in the phone but I was able to recover it myself i let it to dry in rice ? after drying it I cleaned the motherboard and the other parts with alcohol and toothbrush replaced the battery and the phone worked again, PS I sent it to guaranty they told me you have to replace the motherboard and it will cost the same price as a new one at that time, so I don't trust the guaranty after I was able to restore it myself and they didn't

Those lawsuits are for the old phones when Sony advertised that you could take underwater photos with them when that really isn't what the devices are designed for. You are contradicting yourself with those.
This is the key point "The equipment is suitable for continuous immersion in water under >conditions which shall be specified by the manufacturer.<" and Sony has specified that the phone can only be submerged in tap water if you do NOT use the phone when it is submerged. So yet again you contradicted yourself.
Why do you think Sony stopped advertising their phones as being able to take underwater photos? Because of that lawsuit.. Underwater usage is not covered by warranty because it's something Sony tells you very very clearly that you are not allowed to do.
Please, keep contradicting yourself.

You see, the problem is that even if I submerge the phone 1m below the surface of tap water and I won't use it, Sony will not accept the device under warranty if it gets water damaged, and that is something that IP rating allows me to do, and Sony won't acknowledge. So you see, looks like you are contradicting yourself .
It's funny that Samsung and other manufactures don't have a problem with acknowledging warranty claim for water damaged IP68 phones.
WHAT THE ****, I used my phone in the rain because there was a rare pokemon on pokemon go (lol i know) and I went home while the battery ran out eventually when i got home but I let it dry first so after 40 minutes I put it on charger NOTHING HAPPENS. I'm putting it in rice right now for the night, what do I do if it won't ever turn on again? Is this under warranty???
Panic!!!!!!
Dude, it's like the Note 7. It was said it's water resistant but it gave a "check ports" warning after 5 minutes in the water. Never take any "Waterproof" gadget stuff seriously. As it says it's "Resistant". Not "Immune". How much the device will resist is always a mystery in any typical case.
But I don't think that it would be a problem if you'd just shoot a few under water videos for a few minutes. Just don't keep the phone submerged for too long and it should be ok.

I was about to quote from Sony site the conditions for water damage warranty, and I found this, that's weird.
" Take your device swimming
If your Sony smartphone or tablet is waterproof to IPX8 standard*, then you can use it in a chlorinated swimming pool. However, avoid keeping the device in the pool for too long and remember to rinse it off thoroughly with fresh water once you get out.
Over time, chlorinated water can corrode the rubber seals, so prolonged use in chlorinated water is not recommended. But if you want to use your device to get underwater close-ups of a spectacular dive or your child’s first swimming lesson, go ahead.
* Sony devices that are rated IPX7 or lower should not be exposed to chlorinated water."
http://support.sonymobile.com/global-en/dm/water-and-dust-resistance/
Did they change the policy with using the phone in water?

Yes they changed the policy with using the phone in water because you know, they got sued over it. You were the one that linked the lawsuits but seems that you either didn't read the articles or you have the memory capacity of a goldfish.
The support page you linked is an old support page from before they got sued. If you actually use the website to find the waterproof article you will find this: http://support.sonymobile.com/gb/xperiaxzpremium/dm/waterresistant/
Using google will give you old results because that's how google works, more links to a page and more visits on a page puts it higher up in the search results and I can guarantee you that an old article for the Z-Z5 series will have a lot more visits and links than a new article for the X-XZP.
Do not expose the device to seawater, salt water, chlorinated water

Here is also a quote from the Warranty Information PDF you can download for the device.
This warranty does not cover any failure of the Product that is due to:
• Use in environments where relevant IP rating limitations, if applicable, are exceeded
(including liquid damage or the detection of liquid inside the device resulting from
such use).
Click to expand...
Click to collapse
You are under warranty as long as you use the phone within it's IP rating limitations, which in this case is up to 1.5m and 30min in TAP WATER in standby mode. They can test if the phone is still waterresistant or not by pressure checking it. If that pressure check fails then your phone was probably defect and the warranty is still applicable BUT if the pressure check doesn't fail that means your phone is still waterresistant and you 99% likely didn't close the tabs correctly and that's why your phone was water damaged. Also, don't think about artifically making the phone lose it's pressure sealing if you get it water damaged because they will most likely notice that.
Most people that had water damaged Xperias didn't close the covers correctly and was denied their warranty, that's probably where you got the idea that "Sony doesn't accept water damage in their warranty" from. Some people had defect phones and those people did get the phone fixed/replaced under warranty.

You can watch these videos that i found, the first youtuber actually tried that on the Poco F1, he put the device on a bowl full of water for a minute approximately and it survived, however, the device has no actual water/dust protection on any port/slot as seen on the second video, so, everything is confuse.

Like how JerryRig say, the phone is NOT WATER RESISTANT at all. It was advertised as Splash proof due to whatever coding it has.
That means it can resist to some spashed and maybe during rain conditions?
The article is pretty much fake. It does not provide nothing but just words. I never seen a non water resistant device resisit a washtest, as water gets in the device.
It is water resistant or something along those lines
https://mobile.twitter.com/jaimani/status/1032672826472325121
It is supposed to have a similar costing as to Motorola phones. It is good to know but definitely not something I want to purposely try out
As for now, there is no official IP Rating posted by Xiaomi
It is confirmed that it is Splash proof, not waterproof
Problem is, water might not instantly kill the device, but components could slowly oxidize and kill the device down the road. Like that guy that put the phone underwater for a minute, it still works fine, but I'm sure some components oxidized and shortened the lifespan of the device.

My wife's phone went in dishwasher a short time

So we found it in dishwasher and dried it off and everything work fine. When we tried to charge it after it was out of battery an triangle alert came on screen asking with a water splash sign that alerted is there was water in phone. She used a cutie gently and dried off charging portal, still nothing. Then she removed s pen it was wet. How can she she dry it. She can't live without phone. Chuckle. Note doesn't want to wait till tomorrow to take to store. Also we can from Apple and assumed these were water proof.
Thanks
Point a fan directly at the port. Let it sit for awhile.
Its a hot or miss with that cuz is a software bug. At least I remember I took a shower with a phone a few years ago samsung and no matter how long I waited or what I did it continued to give me that warning. Ended up having to put a claim in with Verizon. That was way back with the s8 plus so idk if they made it better. Nvm just remembered I didn't take a shower with it, I actually took it in the ocean with me lol

Phones aren't meant to tolerate any type of forced water like jets from a dish washer. But if it worked normal, I'd say use wireless charging.

Resistant and resistance has a threshold that I would still take with a grain of salt.
They are water resistant not water proof unfortunately so water can get inside.
As someone else mentioned try wireless charging once your pretty sure it's dried out inside.

Putting electronics like mobile phones in rice is a myth .
It's been proven that it does not work and won't help since rice can't suck water out of device that has got water inside the device.
Warm dry area for a few days, ideally surrounded by Silca Gel you get inside different packages such as food or sensitive items that should remain damp free
Ummm how did the phone end up in the dishwasher, im dying to know lol.
Thats a new one for me .

If you have a dishwasher that stands under sink or w.e it's called in kitchen then if the phone was laying above and one of drawers in the dishwasher was pulled out probably top one. My guess could be she/he accidentally knocked down the phone so it landed into first drawer and when they pushed it in and closed the dishwasher they didn't notice the phone was in there. Just my guess but still quite odd how it really got there.

The fan idea in a warm dry room is the safest bet.
If it has a good charge, use the phone and warm it up.
Watch from any sign of malfunction other than the warning.
If anything behaves abnormally power it down asap and do not power up again. It may limit help the water damage.
It will need services if so... at the very least the back needs to come off so it can dry.
Forget rice; use anhydrous isopropyl alcohol to flush out water contaminated electronics. Save my coffee dunked Buds case like that. Yes with a live battery. Still working a half year latter. I flushed it within a minute of the coffee plunge.
Alcohol can craze polycarbonate plastics; be careful. Dry it with low pressure air quickly if possible.
I've use a blower bulb (the kind you use to clean cam lens) and low pressure air to clear a rain drop from the C port.
I then let it sit for about an hour afterwards until the warning cleared.
DO NOT apply power if warning is still on since you know it was water exposed. If water is still present it can cause extensive damage if power is applied.
Do Not use high pressure air as you can force water past the seal and into the phone!
These phones are well sealed so you'll probably be ok especially if it was in a case.

Putting electronics like mobile phones in rice is a myth .
It's been proven that it does not work and won't help since rice can't suck water out of device that has got water inside the device.

Worked ofr my late dads iphone , maybe a coincidence
Rice is not a good desiccant... in any event even a great desiccant is not what's needed here.

Well to be honest rice didn't do a thing to your iPhone trust me. If you left it for a day or two in rice you can just as well leave phone alone without rice for 1 or two days and you will see same effect. So professionals did a test and proven the rice method is false and is just a waste of time and a myth.

Do you have a source for that claim? Here's a published, peer-reviewed controlled experiment that showed that for other wet electronic devices (specifically, hearing aids), rice was in fact a good desiccant, comparable to commercial desiccants:

You know that government can put lies and false facts on their sites too? Secondly hearing aids is something else than smartphone and tablet and so on.
I'm going to look for some proven source since I remember seeing few where they tested and got result that rice does nothing to smartphones, tablets and such and that people going around telling other people out there to use it is a falsely and a myth.

Lol, it's a conspiracy by the rice lobby! Better alert QAnon!
It's a peer-reviewed scientific study. It happens to be archived on a National Library of Medicine website, but it was not "the government" that conducted or published the study.
When you track down the source for your claim, you'll probably find it was a repair shop trying to drum up business. [EDIT: Yes, you've added your sources now and that's what they are.]

A domain that ends on gov belongs to government so link you shared is a government owned business.
Secondly I think you are on wrong track, most professionals that are not repair shop have tried method and gotten result that rice does nothing that's how it was proven it isn't working. I given you two source and none of them are repair shop so seriously wake up.

So sources that conflict one another. What's new. But I hardly think discrediting one because it says .gov is reasonable.
Its from the national medical library talking about the drying out hearing aids for Pete's sake.

Question S22 Ultra Sets User's Hair On Fire

Samsung can only hope this is an isolated instance!

Just think about it, you're sleeping like a baby and as your eyes slowly open you realize YOUR HAIR is on fire. Who wouldn't be absolutely freaking out?
Great find!
A couple of my friends, my son, and myself all have our S-Pens smell like smoke and are very warm when the S-Pen is pulled out. I'm fairly alarmed that the location of the burn marks align with where the S-Pen is located...

just pulled my S-pen out to smell it ----- darn, it does smell burned. There are no signs to the coating or anything, but the smell is very much of burned resin. I think these are all black, right? wonder what one with a lighter color looks like.
Never felt that mine was warm when I pulled it out so far though. Could be a manufacturing issue too and not related to heating while in the phone. Need somebody who receives it new to confirm.
Can confirm my pen has the acrid odor. It and the phone are cool to the touch. Not losing any sleep over it.
Note8 and Note9 also had the funny SPen smell...

If you clean it, the smell goes away.

The same can be said about things that are put in holes. ;-)
I'm no expert in fire forensics. Samsung stated in the article it was caused by an "external source" but how did they make that determination and what was the external source? They offered no evidence besides their general statement. Plus is there anyone naive enough to think Samsung wouldn't look to point it's finger at anything besides themselves? After reviewing the photos it sure looks as though the device blew up and caught fire. The good news is it doesn't look to be a widespread issue.
That nightstand didn't inspire me with confidence that there wasn't an external source, either.
The most convincing photo for me that the device caused the fire is this one. The orange colorization on back of the device doesn't look to be caused by an external source, it looks as though the heat emanated from the inside of the phone.
That phone looks like it went through hell before it was ever exposed to an ignition source or was an ignition source.
Take a good look at the camera array and also the 2 images of the phone. Things aren't adding up for me.
Also far more fire damage in the drawer compared to the top where the phone was located. Could have been a vape pen in the drawer that ignited the whole works.
Looks a lot like possible fraud intent.
Plus, the side that supposedly caught fire is the SPen slot? There's a wire (charging cable?) in the photo there too, if the phone wasn't on charge, was something else? To me, the phone isn't damaged enough for it to have been the source of combustion - but I'm no forensic expert!
I don't have a UK S22 Ultra (mine's an HK import) but I thought Samsung stopped printing the regulatory text on the back with the S9 / Note9?

The Daily Mail didn't write it. Like I said, the Daily Mail is not a reliable media outlet.
I just read this thread and it might hold some truth. My S-Pen is 'melted' possibly due to heat generated while charging. The phone had got really warm (about 40-42C) but I never cared as I charge only till 85%. I did not use the pen for a couple of days and when I try to remove it, I was in for a surprise. It got stuck inside the housing and I had to use a 3M tape to remove it. Samsung refuses to replace it here in India and charges $50 for replacement.

So what was Samsung's excuse for not covering this under warranty? They used to be pretty consistent but we're seeing more and more they're refusing to accept responsibility for obvious defects.
Probably because they don't see how 40 odd degrees would melt an S Pen?

They said Spen is an accessory and wont be covered under warranty. I do not believe this at all and have escalated the issue to their higher ups.
