How does liquid cooling work on phone?

[NokiLumia520]

Can someone please explain how does liquid cooling work on Nokia Lumia 950/XL

Thank You

I would also love some more details on the liquid cooling aspect of these phones!

I'm not sure about details with this specific device, but in general liquid is used to absorb heat.

Liquid would flow through some sort of housing that is next to the processor. As the liquid flows by, it absorbs heat. That liquid then goes by a fan or vent where the heat is expelled.

The idea is that the liquid absorbs most of the heat and brings it directly to the fan or vent so that less heat just sticks around the inside of the device.

I'm guessing it's just a hollow metal plate filled with liquid that faster disperses the heat to the rest of the body. I don't know how easy it would be to puncture though.

Yeah I wonder if this was asked during the Q&A. How this can be achieved on a phone. Or would it be just a simili :-o

looks like a heat pipe, sony already introduct that way back to their Z3

I don't see why MSFT trying to claim this as some deskop level liquid cooling tech. In fact, there's too less detail had been released in this event and I'm a bit disappointed.

What happens after it dries out?

 

[Tien-Lin Chang]

errr....it won't

the heat pipe is a close loop which the liquid inside has bigger heat capacity while outside metal pipe transfer heat fast so it can carry heat away and release it where the outside temp is lower in the oppsite manner.

Interesting!

Haven't heard of it. Must be a new technology.

Panos actually said it was "tablet class" - not desktop class

It's just marketing. It's definitely a heat pipe

agreed its a heat pipe... i was just correcting the fact that he called it tablet class and not desktop class

anything that distributes the heat more evenly or removes it from the SOC will be beneficial...

Not a true heat pipe. Looks the same, but uses liquid, most commonly ethylene glycol, instead of dry air to cool. Liquid cooling is basically taking a heat pipe, making sure it's a sealed, closed system, and adding liquid instead of air to move through the pipe.

It's a sealed loop. The liquid cannot escape.

Again, Not a true heat pipe. Looks the same, but uses liquid, most commonly ethylene glycol, instead of dry air to cool. Liquid cooling is basically taking a heat pipe, making sure it's a sealed, closed system, and adding liquid instead of air to move through the pipe.

The liquid heats while in the evaporator area over the CPU, which causes it to expand into steam and be forced through a pipe that leads to an area called the "condenser" which will condense the liquid from a steam back into a liquid state. This cools the liquid, allowing it to complete the loop and bring cooler liquid back to the CPU again, which will in turn start the cycle over again.

Yah I already posted in another thread. It's a heat pipe with capillaries to carry about 1 drop of liquid. It was basically shown in a tear down of the lumia 950xl. So it's still a heat pipe but with the additional design.

So it's still a heat pipe but with the additional design.

But when you say, "It's just marketing. It's definitely a heat pipe." as you did in your previous post, you make it sound as if Microsoft falsely advertised liquid cooling when they did not. Almost all efficient cooling systems use some sort of pipe. The difference is between dry air being moved and liquid being moved, which is a huge difference with the efficiency level of the cooling. While it's not an "active liquid cooling" complete with pumps and an external reservoir, it is still much more efficient than a simple heat pipe, and a heat pipe is more efficient than a simple heat sink, and a heat sink is more efficient than nothing.

Yes i mentioned it prior to seeing the tear down. But even in the tear down it's called a heat pipe with liquid. So yes no doubt it's a liquid cooling solution, but people still need to know it's just an advanced heat pipe. Even the tear down called it this. People associate liquid cooling with advanced desktop cooling systems. This helps a bit but not as much as true liquid cooling would. But yes for arguments sake it has liquid cooling
