What is a Vapor Chamber?

A vapor chamber is a vacuum sealed heat spreader with a wick structure lining its inside walls. The wick is saturated with a working fluid and when heat is applied, the fluid at that location immediately vaporizes and the vapor rushes to fill the vacuum. When the vapor meets a cooler wall surface it condenses, releasing its latent heat. Learn more about how they function and their role in the thermal management of electronics with this video.

A very good heat sink production expert! perfect

[ekenedilichukwuekeh]

Thanks a lot ATS! I've been looking for a valid explanation for a while! So it was a planar heat pipe this whole time 🤔

Now that is such a C00L video ! :-D

get it ? because it's a video of vapor chamber cooling... :-) - ok, ok, I'll show myself out...

Hello, when you say that one works only in one direction while the vapor chambers does it in both, does it mean that it acts like a heat diode ? Does it work also to transmit cold ?

So, from processor heat spreader there's 400w/m2k copper to thermal paste 4-15w/m2k or 76w/m2k for liquid metal, than it transfers to again, aluminum or copper, 200-400w/m2k with a surface and wick that transfer heat to water that is 1w/m2k on all that wick surface of 200-400w/m2k that is linked to the real cooling surface of aluminum fins, not the transfer from processor to the fins, bit the real cooling surface that is 200w/m2k of aluminum fins surface. So even if there's 1000 000w/m2k of transfer of temperature, what is the surface that is cooled by fans and how well it performs better by weight and by volume of a heatsink with heat pipes? %?

Nice video!
What comes to mind is, what is the best solution for a CPU PC ? I would think a bigger vapor chamber would be better to dissipate the heat than just pipes?

u also makes Vapor chamber in smartphone ?
xiaomi 11i has one
