I have a question that maybe you can help me with, i know heat has tendency to go up but many high end heatpipes for computers actually conduct heat in every direction with a very good level of performance and consistency like the Scythe Katana 3, it conducts the heat down and then up or up and then down depending on the orientation and the performance is very good on both orientations (maybe a bit different but very good) and it conducts the heat down through the pipe. I can't understand it
@WXIIIR Vertical heat pipes use gravity to let the working fluid condensate fall back to the heat source. Horizontal heat pipes use an internal wick to suck back the condensed fluid using capillary action. I don't know the detail of what kind of wick is used though.
@aridya1 i researched it a bit, the best to overcome gravity is what they call 'sintered powder' on the walls of the tubes (the one you talked about seems to be right before it), it doesn't seem to me like a simple thing to get right doing at home nor getting it nearly as efficient though :-( . After this i searched a bit to find vendors of heatpipes and they are monstrously expensive when sold separately, it seems my new cooler design will have to wait :-( . Thanks for the answer
if you have a vacuum inside, then water boil under low temperature. I doubt about that inside is liquid, it's already gas, otherwise this could be not water but mixer with another materials.
The audio is HORRIBLE on this video....either use another mic., such as a clip on or a better directional type.

Does the heated end have to lower for the heat pipe to be effective?

@pdaddy168 I have the same question. Because in cpu coolers, heat pipes are horizontal. So where does the water vapor go?

@Heanas7 So if I for example take a coke bottle and fill it with water...then manually put a vacuum on it using my lungs, I can boil the water??!!?

I got a heat pipe for ya. Right here! (Points to crotch)
