If you seal the cup / put a lid on and had the heat pipe go through the lid, would the heat pipe cool down the water to room temperature? Would that happen fast?
it is possible to change the pressure and the "refrigerant" inside the heat pipe to adjust the condensation/evaporation temperature for different applications
Does it matter if the pipe is vertical or horizontal ??? How about pipe length, is there a maximum length that can be used for this process of passive heat transfer ??? Thanks
It should not matter if the pipe is vertical or horizontal, as the liquid moves by capillary action. But for larger systems, like a solar thermal collector, when slanting it has an advantage as the liquid flow can be assisted by gravity. it is a good question about max length. I suspect there is, and probably limited by the flow rate of the liquid back from the cold side. So, slanting it with heat source is at the bottom probably can allow longer heat pipes to work
No energy used as in no need for circulator pumps or fans for heat distribution. The wicks allow the condensed liquid to flow back down to the evaporator section using capillary action; otherwise the condensed liquid would tend to just stay up at the condenser section instead of working its way back where it's needed to continue the cycle.
The best explanation on this I’ve found on TH-cam.
Heloooo! Love your sense of humor and the way you clearly explain stuff.
You are truly the best teacher on this universe..
Superman may not see temperature differences, but he may see that one of those "rods" is actually a pipe!
thank you for the comment. Sorry, I forgot to clarify that both of the rods are pipes, one without water inside and one with water inside.
Great video!
super useful! Thanks
Thank you!
😬👍
Thank you!

yes, the heat pipe will cool down the cup faster, as it conducts heat out of the cup faster
Great!! Can Heat pipe conduct cold temperatures below -2 degree Celsius and frozen up !!!

Neat

@@denisywyu7864 Thank you for answering my question Denis. Peace vf
At 4:19 Did you mean to say Copper "Rod" not "Tube" because a tube is also hollow, which is what I thought was what made a Heat Pipe a heat pipe?
A heat pipe has a little bit of water in it so the water can evaporate and conduct the heat faster
Where can you buy heat pipes for cheap?
I bought mine from Taobao (alibaba) online. There are different size and shape, copper and also aluminum ones, etc. Maybe can try looking there
4:00 - no energy used? - what boils the liquid? They are not just hollow tubes, they have a wicking liner..why?...sooo - where is the secret?
