There is a thing called heat pipe saturation where the small amount of water literally vaporizes and becomes ineffective at transferring heat. It’s especially problematic when you’ve overclocked your CPU or GPU or really anything you’re using to transfer heat. Once the pipe gets over saturated and the water vapor flashes to steam, the heat pipe becomes ineffective.
It does not become ineffective, it just has a limited heat transfer capability unlike traditional solid materials where the heat flow is proportional to the temperature gradient. So if you heat pipes are designed for 200W but your CPU produces 250W, you are screwed.
Heat pipes are just copper pressure vessels filled with a gas that liquifies at relatively low pressures at room temperature. Cooling the pipe causes more of the gas to liquify which causes the gas/liquid to “slosh around” It’s not more conducive, it takes advantage of well known physics phenomena to physically move the cold/hot matter from one end of the pipe to the other.
Well, to explain it from the opposite perspective, technically a heat pipe is filled with a liquid that evaporates at relatively low temperatures above room temperature (often water sealed at low pressure, from what I gather), as they are usually designed to transfer heat from parts that become hotter than room temperature. Perhaps the one in the video is like you say, filled with gas at room temperature and condenses below it. And to elaborate more on the physical phenomenon, it is _latent heat,_ where the phase change of a substance (in this case between liquid and gas, latent heat of vaporization) requires much more energy than its standard specific heat (i.e. energy required to raise the substance 1 degree Celsius).

@@TLguitar “perhaps the one in the video is like you all, filled with gas at room temperature and condensed below it” That’s how *all* heat pipes work, the contents of the pipe are not under atmospheric pressure, which affects the boiling point of the gas/liquid.

Yes. That'd be a great invention. Plus heat pipe & icecream scoop...where u put hot water in handle, screw on top, then it heats up the scoop but stays warmer than other scoops.

Thank you so much for these videos. They were rather frustrating at first but I greatly appreciate the chance to problem solve in a way that will likely be very useful later (and right now) in life.
I'd always heard of air-cooled heat sinks for CPU's using heatpipes. I thought it was all about surface area and efficiency of heat dissipation. I had no idea it had more going on.
The fun part is that even for satellite and thermal design heat pipes are considered as "perfect" without inefficiencies. Only the thermal input and output block have the regular inefficiencies.

Heat pipes are actually used in your gaming computer components like the GPU cooler and CPU air cooler (tower ones) which have the heat pipe to cool the CPU and the GPU , heat pipes are the reasons why your computers stay cool and you make your day good
4 mm doc is kinda impressive. I‘m used to work on medium sized Weiler lathes (model Weiler Praktikant 160 and Weiler Condor B) and most I‘ve ever done was 2 to 3 mm in aluminium
just FYI these are the technology that enabled large air cooled chip coolers to actually work better than milled block heat sinks, enabling the Pentium revolution of computer chips that took PC's from fancy calculators that could run at like 5MHz to the 4-5GHz super computers that can crunch millions of polygons a second while simulating a literal army of characters in a video game. Consider how complex even lowly Minecraft is with its voxels and how much a game like that would destroy a Commodore 64 from back before heat pipes were invented. And now we take for granted the typical, even budget, CPU is more than enough to calculate millions of voxel blocks on screen at a time. NONE of this would have been possible without heat pipes, because they are never going to sell active water cooling to the masses because of the cost, size, weight, and risk of the pumps failing.
When I was a young child, I would play with ice cubes in the bathtub. The faucet would always melt the ice cubes just like this, albeit a bigger melting surface area since it’s a faucet and not a stick. Cool video!!
That's cool! I was a phd student in mechanical engineering and I studied heat pipes. They are indeed badass heat conductors. It looks like conduction from the outside but it is actually phase change that does the magic. Phase change and the energy released is also why steam will burn the crap out of you very quickly.
@dalebob9364That is wrong, not sure why you are so confident. Water is commonly the phase change material in heat pipes. If it were sodium, it would not work. It's a liquid/vapor phase change and sodium remains solid at all the working temperatures of heat pipes.
In our senior year in high school our class developed a steam engine utilising hundreds of these in a lattice, the engine was so efficient that UCD came to test it and bring it to their labs
What "pushes" the evaporated coolant to the other side? Seriously, this is amazing though. I always thought they used heatpipes instead of solid copper in computer and laptop CPU/GPU coolers to make them cheaper/lighter! I never would have guessed it's actually because they conduct the heat away faster!
I'd like to see a comparison including similar thickness tubes. I figured energy transfer through a tube was quicker with a tube over the rod but I didn't realize he had a magic stick instead.
Fun fact: this is why ice cream shops use that same simple scoop you're probably thinking of right now. It's handle is hollow, so when the heat travels to the actual scooping bit, it's warm enough to carve a perfect round ball out of even frozen solid ice cream.
this is a convector tho, its convecting heat through water vapor and it undergoing a phase transition back to water. It is not conducting heat alone, although the copper is a decent conductor that allows the convection process to start quickly
I feel like it’s easy to underestimate how nuts it was when you “cut” the cube! That’s a pretty thick rod melting such a large volume of water.. that was just wicked fast! Ice does not like to change temp that easily/quickly 🤯
I feel this has been uploaded before. I remember commenting when GN did a factory tour in heat pipes in coolers. Heat pipe failure can be a serious thing in GPUs. I saw a video (was it northwestrepair) where it was constantly overheating despite applying thermal paste and pads correctly. Turns out there's a small hole that pierced through the heat pipe which rendered it useless.

“Instantly turned it black”🔥🔥🔥
that “cutting with your own heat” is impressive
Heat pipe + butterknife = win
Yes. That'd be a great invention. Plus heat pipe & icecream scoop...where u put hot water in handle, screw on top, then it heats up the scoop but stays warmer than other scoops. The same principle could be applied to a de-icing spatula for getting rid of ice/frost around freezers that have built up...or ice on windscreens.
@@mymai5859 professional ice cream scoops already use this principle. They can have water or even better heat conductive liquids and there's no need to pre-heat it. The hand warmth is enough to cut through ice.
Thats super quick heat transference 😮
These vapor chambers have been used in laptops' heat sinks for few years now. Really impressive thermal conductivity
Few years? They've been used in most decent CPU or GPU coolers, desktop or laptop for at least 20 years, probably more.
few decades*
@@billyboy_45 I've seen some old Technics amplifier (early-mid 80s I believe) that use heatpipe to cool their transistors... They definitely been around for quite a while!
Heat pipes and vapor chambers are not the same. They became mainstream in laptops a long time after desktops
@@josephm.6453 I have an old IBM Thinkpad from 2000 that uses heatpipes.
So they have been in use for a few decades now.
Also, heat pipes and vapor chambers are basically the same.
"Vapor chamber" is just a simple name for "planar *heat pipe*".
Thank you so much for these videos. They were rather frustrating at first but I greatly appreciate the chance to problem solve in a way that will likely be very useful later (and right now) in life.
I didn’t realize I was so behind on physics lol
I'd always heard of air-cooled heat sinks for CPU's using heatpipes. I thought it was all about surface area and efficiency of heat dissipation. I had no idea it had more going on.
And now we make bus benches and playground slides using the same concept. Enjoy your summer.
Isn’t this basically how smartphones and other small electronics are usually cooled? Super cool to see!
Not necessarily that small, think laptop size
@@Spudmuffinznot even laptop sized, desktop sized aswell
(unless youre using the stock cooler lol)
Thaaank you for explaining and not just showing ❤️
The fun part is that even for satellite and thermal design heat pipes are considered as "perfect" without inefficiencies. Only the thermal input and output block have the regular inefficiencies.
Nice thats why it looked like plaghdough in there
What if the heat pipe was made out of artificial diamond?
There’s no such thing as ”artificial diamond”. Diamonds are diamonds.
@@ELaster1 "lab grown" you know what he meant. Dont be a jerk.
@@ELaster1 one is lab made, the other is naturally occurring on earth. Clear difference imo
@@ELaster1lab grown bro
@@zigzagdevildog
I know what he meant and I’m not trying to be a jerk. It’s important to point out that lab grown diamonds are just as much diamonds as blood diamonds are.
I want this tech in a frying pan. fast and even heating
Get copper clad steel pans. Very pricey though. $$$ €€€ £££
That is so fucking cool, I’m glad I learned this today!
Heat pipes are actually used in your gaming computer components like the GPU cooler and CPU air cooler (tower ones) which have the heat pipe to cool the CPU and the GPU , heat pipes are the reasons why your computers stay cool and you make your day good
"Heat pipe"
I wanna buy your entire stock
-vsauce
Thats a heatsaber
Yo wait that’s actually so op. Thanks action lab!
hope it doesnt get patched in the next update
I knew heat pipes were hollow copper but I didn't know about the rest. Really learned something today, thanks. ❤
4 mm doc is kinda impressive. I‘m used to work on medium sized Weiler lathes (model Weiler Praktikant 160 and Weiler Condor B) and most I‘ve ever done was 2 to 3 mm in aluminium
“Show you how fast the worlds fastest heat conductor can conduct heat” was like a tongue twister lol
New heatsink for my pc
Same as the old 😂
just FYI these are the technology that enabled large air cooled chip coolers to actually work better than milled block heat sinks, enabling the Pentium revolution of computer chips that took PC's from fancy calculators that could run at like 5MHz to the 4-5GHz super computers that can crunch millions of polygons a second while simulating a literal army of characters in a video game.
Consider how complex even lowly Minecraft is with its voxels and how much a game like that would destroy a Commodore 64 from back before heat pipes were invented. And now we take for granted the typical, even budget, CPU is more than enough to calculate millions of voxel blocks on screen at a time.
NONE of this would have been possible without heat pipes, because they are never going to sell active water cooling to the masses because of the cost, size, weight, and risk of the pumps failing.
When I was a young child, I would play with ice cubes in the bathtub. The faucet would always melt the ice cubes just like this, albeit a bigger melting surface area since it’s a faucet and not a stick. Cool video!!
That's cool! I was a phd student in mechanical engineering and I studied heat pipes. They are indeed badass heat conductors. It looks like conduction from the outside but it is actually phase change that does the magic. Phase change and the energy released is also why steam will burn the crap out of you very quickly.
"What is the fastest heat conductor?"
*Puts ice*
I've got a joke about a heat pipe but it's NSFW
😏
I'm unemployed, tell me the joke
do it lmao
Is the heat pipe made out of copper? 😅
Yes
Only in some
@dalebob9364That is wrong, not sure why you are so confident. Water is commonly the phase change material in heat pipes. If it were sodium, it would not work. It's a liquid/vapor phase change and sodium remains solid at all the working temperatures of heat pipes.
@dalebob9364quit making shit up
@dalebob9364 Spreading misinformation for a couple of likes has gotta be the lowest of the low... man, go touch grass.
In our senior year in high school our class developed a steam engine utilising hundreds of these in a lattice, the engine was so efficient that UCD came to test it and bring it to their labs
The power of heat in the palm of my hand, Peter!
Bro made the dragon slayer outta a heat pipe rod
i came here for this comment, Thank you
This is the coolest thing I've came across this week.
Heat pipes are a brilliant application of basic physics
Rod: me when started sleeping
Pipe: me when I wake up
I think this is the single most amazing thing you've taught me. Also, someone has to have made this thing out of gold or diamond.
Looks like an experimental album cover
Bro just unintentionally made the dark saber.
this is an awesome way of visualising heat transfer
What "pushes" the evaporated coolant to the other side?
Seriously, this is amazing though. I always thought they used heatpipes instead of solid copper in computer and laptop CPU/GPU coolers to make them cheaper/lighter!
I never would have guessed it's actually because they conduct the heat away faster!
Also diamond is a really good heat conductor
This is why they're used in almost all of your electronics that need active cooling but they have their limitations.
And this is why they're used in high-performance PCs and gaming Laptops
Finally someone telling the sheet is made of LC… Nice explanation!
I'd like to see a comparison including similar thickness tubes. I figured energy transfer through a tube was quicker with a tube over the rod but I didn't realize he had a magic stick instead.
This man has an access to vibrating swords
It is a good application for different concepts
Oh... wow... that's a thing I didn't know, but should have and now I am in awe of the genius that came up with the idea.
Yeah I'm glad you showed the ice slicing that's incredible
This is what all good modern PC coolers are made with!
Fun fact: this is why ice cream shops use that same simple scoop you're probably thinking of right now. It's handle is hollow, so when the heat travels to the actual scooping bit, it's warm enough to carve a perfect round ball out of even frozen solid ice cream.
“Hi um can I get a burger with fries please and a coke?”
“Sure ice or no ice?”
“Liquid crystal”
this is a convector tho, its convecting heat through water vapor and it undergoing a phase transition back to water. It is not conducting heat alone, although the copper is a decent conductor that allows the convection process to start quickly
That was cold, chilly, and breezy
And truly heezy
This is just the phase transition properties that in large scale is superconducting
I feel like it’s easy to underestimate how nuts it was when you “cut” the cube! That’s a pretty thick rod melting such a large volume of water.. that was just wicked fast! Ice does not like to change temp that easily/quickly 🤯
I feel this has been uploaded before. I remember commenting when GN did a factory tour in heat pipes in coolers.
Heat pipe failure can be a serious thing in GPUs. I saw a video (was it northwestrepair) where it was constantly overheating despite applying thermal paste and pads correctly. Turns out there's a small hole that pierced through the heat pipe which rendered it useless.
