In this video I show you the world's fastest "conductive" heat transferring device called a heat pipe. I show you a visual of how fast it can actually conduct heat compared to copper. Then I actually cut it open and show you what's inside and explain how it works!

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.

Since I don't have the ability to melt sintered copper powder to the solid copper, I'll probably use something like copper mesh or maybe fiberglass for the wicking material. I also have some diamond powder and may chuck some of that in as well.

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.

@vincentrobinette1507 4 жыл бұрын

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.

@PattyDung 4 жыл бұрын

@@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.)

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...

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

@456MrPeople 4 жыл бұрын

Yeah the problem is that any heat it does transfer also heats up the liquid causing it vaporize due to the low boiling point.

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

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.

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. kzfaq.info/get/bejne/jJt2rKmnzN65mHk.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.

@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

So I think I'm noticing a potential drawback of this device. Isn't it true that it's thermal conductivity would have to be lower at very cold temperatures? Say if you're significantly below the triple point temperature of water, like -40C, then the vapor pressure of the ice would be so low that the vapor cannot transfer as much heat to the other end, yes?

@vincentrobinette1507 4 жыл бұрын

This is precisely why I suspect that the working fluid might be methanol, or some kind of alcohol, or even dichloromethane. These fluids work well below the freezing point of water, as long as the condensate will wick effectively back to the source of heat. Even if it IS water, if the temperature is that cold, the temperature protected component still won't get that hot. If it does, the water turns back to liquid, allowing the heat flow system to resume normal operation. Remember, it's vacuum packed, so water will freely evaporate and condense, at any temperature, with changes in vaporization pressure. The interior is always under a vacuum, unless the whole heat pipe gets up to, or above 212 degrees, in which case, there is no pressure difference, or even slightly positive pressure.

@justinw1765 2 жыл бұрын

Yeah, but it's not typically used under those conditions. It is typically used around room temps to a heat source that may vary between 100 to 200 F. Water has a higher heat capacity than methanol and many other, non exotic fluids. It is very good at transferring heat via the liquid--vapor--liquid cycle. Sure, if you lived in Siberia or the like, and were using this tech outside, then yeah, go with an alcohol or the like. But for most conditions, most of the time, water works very well. As far as I know, most of the heat pipes made and sold to the public use water as the phase change material. Maybe the military and the like use different and/or more exotic materials for some applications?
