Diamond is really good at conducting heat as well, I went to a science demonstration where they had a large block of ice and a small blunt knife made of synthetic diamond, it cut through the ice in a very similar way to the rod in this video
5 x copper
Diamond is an excellent thermal conductor, I believe it's due to the crystalline structure of the carbon within. Diamond which has a more well structured crystal lattice works even better, but you'll be hard pressed to find such a diamond naturally.

It's the fastest because it's not just conduction, it's evaporation, condensation and convection. In the solid copper rod, the copper never moves. However, in the heat pipe, the water on the wick is a working fluid that moves through the center of the pipe, which is a region of pure water vapor.

Ooh so that's how vapor chamber cooling works in electronics
Vapor chamber is very similar to an heat pipe, but the heat pipe is a little bit slower in conducting heat
nope, vapor chamber is a little bit different from heatpipe
@@clee2423 how so?
@@threepe0 instead of small surface area at the outside like heatpipe, usually vapor chamber has a wider area so the heat will spread more evenly and faster
@@clee2423 I don't think that really qualifies as different; The "how it works" is essentially the same, just a different shape
Great video! The visual testing was amazing. I always wondered why they just didn't use a solid copper pipe, I always assumed if the copper was hollow to reduce material and save money.
This guy is a genius. I have been roaming all around you tube the whole day watching car races, bike races, huge trucks blah blah( came here at 10am now it's 11:35pm) East african time (Uganda) skipping his videos and I just clicked on his video as I go to bed ( because I like to concentrate on things that matter before going to sleep) and I felt so at home.

Dude, I think you have the absolute most awesome job ever.
These copper water heat pipes are used in a lot of smartphones(not on iPhones) recently to help in efficient heat dissipation. It's a bit of the different design made according to the smartphone body. In a few teardowns, you can see the water evaporate as the person tears through the pipe. It's really cool. Finally got an idea about how it works😃.

Brilliant video! Very well explained, thank you for sharing
one very big issue here is that you're using a rod vs a pipe, it would be much more interesting to see the heat pipe vs a hollow copper rod, due to the difference in mass and thermal capacity.
dahahaka not really because copper is a better thermal conductor then air so having a hollow copper tube will transfer heat slower than the copper rod
@@jstew2938 you know what's even worse than air at conducting heat? Vacuum. The heat pipe is basically evacuated, your argument makes no sense
dahahaka while you are correct about a vacuum having lower thermal conductivity than copper, the heat pipe has a small amount of water in it which in the lower atmospheric pressure in the pipe boils at a fairly low temperature. The water boiling in the warm part of the pipe turns to vapor and condenses at the cooler end of the pipe, which transfers significantly more heat than air or copper would. It’s actually some what similar to the way an air conditioner or refrigerator works.
It would just be an even bigger difference, don't see what's "much more interesting" about it.

dude thanks for this. i learned something new about material science and heat conductivity
Adding on to this: the "spongy" texture of the inside of the pipe is there to increase the surface area on the inside, thus also greatly increasing the temperature transfer
How is the spongy texture created
@@edwardbrant12 its actually a copper powder, if you interested at how it made, here's the video czcams.com/video/p71V6zLybig/video.html
No. It's because the liquid water gets spread to the entire inner spongy lining. A smooth surface will create a drop of water that will move here and there due to gravity and won't boil on the application of heat on the other side so, it won't work.
Bro it's never temperature transfer.... It's heat transfer.. There is a difference
Also the spongy part act as a capillar bringing the condensed water from the cold side back to the hot side, where it evaporates and goes as vapor through the middle of the pipe.
Creating a closed cycle.
Just my guess, I am actually an idiot.
One drawback: once all the water has moved from the hot side to the cold side, the thermal conductance of the tube reverts to that of a hollow copper tube. Of course if the hot and cold sides are subsequently reversed, the conductance dramatically increases again, but only temporarily. In this sense, the tube doesn't act like a super-good conductor of heat long-term in one direction or the other.
That's why the wicking process is so critical, to the continuous flow of heat from a source to a sink. That's what returns the condensed liquid back to the source of heat, and is the limiting factor to how fast heat can be transferred. It would be easy, if the heat source is below the heatsink, because gravity would just drip the condensate back to the bottom. Wicking is required, if the heat source is level with, or even above the heatsink. That's why the inside of the tube is rough, so the capillary effect can wick the condensed water back to the heat source, after it has evaporated.
@@vincentrobinette1507 That's a good explanation. From looking at the specs of the best heat pipes (those with a sintered internal wick) the skinny pipes really are about 100x the conductance of solid copper of the same volume, and at low power densities, heat pipes continue to operate at that high efficiency indefinitely. At higher power, the efficiency may be reduced, depending on the tip angle, and at still higher power, the efficiency goes way down, even if horizontal. (Note that in the video, that size of sintered-wick heat pipe would probably rapidly go into inefficient operation if maintained at ΔT= 30°C, the approx difference between the hand and ice, but the warm end probably cooled rapidly to about 4°C. There was probably a rapid melting of the ice initially because the warm end started at hand temperature.)
Amazing! Keep up the good work
when i saw how it works the first two minutes i thought of it and before you reveal it i knew how it was working and it’s inside as well, so happy i figured it out before you explain it haha :D

I've repaired hundreds of laptops and always wondered why many looked like hollow tubes crimped at the ends. I suspected increased surface area but after your fantastic video it all makes sense :) WD!
Great video and info! Thanks
That is exactly what I was looking for.
Thanks.
Alright this is absolutely fascinating. I was expecting some kind of alien material with insane properties. I'm sharing this with all my nerdiest friends
Interesting. I always wondered what was special about the copper heat pipes in CPU/GPU coolers.
Ikr I was like why they are so much better than stock cooler that blow air directly on to the cpu, you feel me?
I was remembering a GPU with weird copper pipes
Thanks alot for this informational video. I always found it intuitively unlogical that those high mass cooling surfaces are connected by thin copper tubes. I thought without deeper knowledge that copper shouldnt be able to transfer enough heat quick enough with those low radii. I didnt knew those things existed. Such a genius heatpump. Im amazed.
You have cool experiments and well explained
This is so cool! :D
You should do comparison of that heatpipe between the opened pipe and the unopened one.
And see how much difference it is.
opened pipe gonna react just like a normal cooper pipe, there's no difference between opened pipe and normal copper rod, the water is the magic in the heatpipe
Wait, what about the heat pipe that has a radiator liquid and a wick inside. I swear I've heard that kind of thing.
@@utiantew Then someone was feeding you BS.
High heat conductance of heat pipes is based of evaporation absorpting lots of thermal energy.
With movement of gas then transferring that energy fast to cold end, where condensation releases that thermal energy.
@@tuunaes What he's referring to is a wick used to soak the condensed water back to the heat source more quickly than the copper powder that is sintered to the inside of the pipe. I have wondered if a woven glass fibre wick might make it more efficient because the relatively straight-ish glass fibre bundles would wick water much faster than the tortured path of water being soaked along the copper powder. If you see water soaking up a bundle of glass fibres it's extremely quick
@@clee2423 there IS a difference between a copper rod and an opened copper pipe.
It is in the copper cross-section.
That was really cool, thank you.
excellent demonstration!

"Pc gamers wants to know your location"
Many laptops use heat pipes to conduct heat from the CPU to the heat sink that the fan blows through.
But.....they are used is pc's
This one is used in Mobile Phone
I need this for my pc that takes 20 minutes to load roblox
Edit:My pc overheats while playing roblox
You obviously dont know anything about pc hardware. This has been used in most cpu heatsinks for ages. Vapor chambers work better but its a shape thing. Its just crazy to think that the vapor inside moves faster then the speed of sound
Awfully interesting! The differences in speed of heat transfer in different materials always amazes me.
Thanks for the video, amazing engineering :)
Good job action lab. You're finally back in the algorithm.
All those years of computer building and overclocking and I be like "what isn't that just a regular heatpipe?" 🤣🤣
I really like how this visual played out.
Learned something, thumbs up.
I do HVAC for a living so when I saw that copper tube was pinched on one end I knew right away this was a phase change conductor
Where can I get these rods
I thought the "bad" heatpipe he was holding was the regular sintered copper tube and the "better" one had some rare and expensive material inside it. If you already know about these heat pipes then this video is disappointing.

This the second video out of
two videos of yours back to I back combined with the idea I came up with for retractable 🔭 telescopic blades & aircraft carrier cable to be used on wind farms inspired by watching videos of them structurally failing and decided to donate some time to help these engineers tackle this issue for safety and longevity.
You have a wonderful scientific mind that can be a valuable asset with their production of a solution.
Good day.
Here's the first video that may solve the problem for *the* *runaway* issue with the magnetics locking up and for not locking.
czcams.com/video/V5FyFvgxUhE/video.html
So that video solves that problem because they say they don't have a clutch so now I'm thinking engineering up a magnetic torque converter.. similar to what we use in automotive rather than a fan clutch.
Thanks for another interesting video.
And I must say that although I was quite familiar with both the concept and construction of heatpipes, I don't think I've ever seen any demonstration of them that matched Yours in how simply yet effectively it demonstrated the function and efficiency of heatpipes.
That being said You could have added a bit about the "whicking function" of the sintered ((spongy)) copper on the inside.
Best regards
I wonder if you could incorporate these to make a more efficient Stirling engine or peltier cooling system. I'd love to explore some new experiments with this.
Did you get to know how to use these pipes for peltier cooling system?
0:03 A heat pipe is not material, it’s a mechanism.
I watched Mr. Wizard growing up in the 60’s. Mr Wizard is no longer around so you are my Mr Wizard now. Very well made demonstrations !
it\s very helpful video man that's very nice
Clever design. I'd love to see its replacement one day. Could you imagine what an upgraded version would even look like?
Vapor chamber.
I imagine it would be made of synthetic diamond
They are using nanofluids to replace pure water. Studies have shown big increases of efficiency and conductivity. There's also new materials they are using for the "wick" which also does the same thing. I am not sure if these techniques are being used on a wide scale yet or not, but I imagine it will catch on.
So.. basically as I understand... It's magic. ✨
Oh, check 6:01 ur correct
Awesome demo.
Thanks a lot sir for your kind information
I impressed with your expirment...
Pro tip: you may want to get a small vise, the kind that clamps on the edge of your table, or a Panavise kit if you're being fancy. It's much easier and safer to cut with a Dremel when the workpiece is held securely. (You do wear eye protection when using a cutting disk, right?) edit: I just noticed this video is almost two years old, but never mind...
Good advice, I totally agree
Who cares, if the content creator chooses to be unsafe its of no concern to us VIEWING through a device were nothing can happen to us! And if there is anyone who actually is dumb enough not to follow safety precautions their better off not in the gene pool.
Something interesting related to this video is superfluid helium (I believe helium IV). It's a form of liquid helium that transfers heat almost instantly, it's very interesting. So technically, superfluid helium IV is the stuff that transfers heat fastest
Yeah the problem is that any heat it does transfer also heats up the liquid causing it vaporize due to the low boiling point.
From where can I buy heat pipe?
Pyro carbon conducts heat much better than a copper heat pipe

Search for "thermochromic" or "thermochromism." There's all kinds of products with this feature. Video featured a plastic thermochromic film. (Thermo = heat, chromism = changing color.) Thermometer strips for foreheads or aquariums use the same technology.
Thanks for your sharing
I knew that heat pipes are a better heat conductor than even the best solid conductors, but i did not expected it being that rapid!!!! 😮
Thx for the demonstration! Next time i have to cool somthing, i will take heat pipes more likely in consideration!

@Lalrivunga Hnamte it is not about the video, the context is in comments. Root one asked about both, rod and paper, then someone mentioned paper could be bought, then you mentioned it can be made at home, and that is the point where i was interested in: how could you make thermopaper at home.
and no, it is not that easy to create such a surface on the inside of the copper tubing. Sealing the vacuum with a little water inside it would be easier, but not much, as we need very specific pressure of water vapour in the tube after sealing.
But if it was about thermal paper, i thought, you might just know some chemical available in food or chem store
