The heatpipe was 40cm long with 2,5cm thickness at widest point and was experiencing a 20W heat load. Tell me, how does that apply to ANY smartphone application? You're such expert in thermodynamics yet you don't know that heatpipes are not universal and they are fine tuned for particular temperature ranges and heat loads.
Literally a quote from Wiki about heatpipes:
"Heat pipes must be tuned to particular cooling conditions. The choice of pipe material, size, and coolant all have an effect on the optimal temperatures at which heat pipes work."
Just because it works doesn't mean it's working at optimal or best rate.
But whatever, what do I know...

The liquid doesn't need to boil to evaporate. That's what the wick's very high surface area is useful for. The liquid just needs to be at a sufficiently high temperature (i.e. 60~70 degree C) for it to work efficiently. Also, ethanol and methanol can dry up even in enclosed containers (just like Hydrogen and Helium escape completely enclosed containers). Therefore water is used for electronics' cooling and is the best medium suited for this purpose.

Here's a research paper which compares the heat transfer performance of water, ethanol and methanol, that directly contradicts whatever this poster just wrote:
https://reader.elsevier.com/reader/sd/pii/S2090447913000361?token=4BAAE028C0B7D65910006ECA6BDA7AA967C6BC7EF317482328704701F5F30F67AE02BDB948361753E13440B0BAE2227E&originRegion=eu-west-1&originCreation=20220722210645
Conclusion (a) of the research paper states:
"It was shown that water is the best working fluid among the other working fluids regarding the higher temperature and heat transfer coefficient in the evaporator section."

Cat, 22 Jul 2022There is water inside heatpipes used for cooling electronic... moreI love how confident you are at being incorrect. Yes, water CAN be used. But not for smartphones (last time I checked, we are talking about smartphone application of heatpipe/vapor chamber here) because it's boiling point of 100°C makes it rather useless here. That's where my mention of "fine tuned for application" in my post comes in. The liquid used inside heatpipes defines the temperature range you're expected to have cooled element at. For use in smartphones you need boiling point far below boiling point of water because chipsets never run that hot. You can also have heatpipes that have mercury inside that has a boiling point of 350°C. Which is meant for applications of heatpipes where heat you're trying to pull away is at around that temperature. Using such heatpipe on smartphone or even desktop PC processor would be incredibly infefficient if not straight up non functional.
Water has a boiling point of around 100°C at atmospheric pressure. Tell me, what smartphone chipset heats up anywhere close to that? You can't have an effective heatpipe system if liquid inside doesn't evaporate. Ethanol on the other hand has a boiling point of 78°C. Factoring in possibility of vacuum inside and the boiling point further shifts.
It's also funny how no one noticed in JRE's teardown videos where he cuts into vapor chamber and points his blade at dropplets inside which quickly evaporate and disappear (in matter of seconds). Water doesn't do that such short time. Ethanol however does. I also don't know why they'd complicate things by using vacuum and water to achieve what you can in atmospheric pressure using ethanol. It's easier to manufacture and less likely to leak if it's at atmospheric pressure and just appropriate liquid used inside.

It's astounding what kind of derps are rolling around this place accusing others of "not knowing tech" and seriously believing there is WATER inside heatpipes and vapor chambers. You can't make this s**t up lol

CompactPhones5ever, 21 Jul 20223°C improvement in controlled lab tests, also known as 0,3°... moreI partly agree with you, the thing is phones are so much controlled and everything closely integrated together that it could be possible to have the same results in lab tests in real life. It is not the case for a computer for example, where manufacturers can't make up with the infinite number of combinations of different vendor parts. For phones they seal everything and know exactly what is inside, so they can more easily emulate what is in the lab.
