Why are heatpipes sealed and what would happen if they were opened?

    This is a question that has been on my mind for a while and I can't seem to find an answer.

    I mean, if heat rises and it's sealed at the top, then wouldn't the heat just stagnate? If the top was open, wouldn't the heat be forced out the top for a fan to suck it out? Just curious about this.

    Heatpipes arent just pipes, they are mini phase change systems. They contain a liquid that evaporates when heated, the hot gas moves along the pipe, and gets cooled again, turning back into a liquid, and repeating.
     
    Solaris17, Chewy and JC316 say thanks.

    some heatpipes nowadays are just "hotpipes"

    Ok, the reason that I am asking is that my Thermaltake CL-PO370's heat pipes never get hot. They stay quite cool ALL the time, even when orthos is running and TAT is reporting 60*C.

    Remember when dude modded his Zalman 9500 on water cooling? The thread started exactly this way. there were lots of theories about, and when he cut his open , he found hollow tubes of AIR.

    depending on the liquid inside them,if you open them they will be ruined.without the fluid in the pipes they would not work as intended and would be no good.

    if the pipes were empty they would not work,possibly when he opened them the liquid turned into a gas and escaped making the pipes seem emty.

    if the pipes were empty,they would do no good at all on the heatsink.

    Thats because when heatpipes are cut the vaccuum is broken and the liquid evaporates instantly under standard pressure. :)

    When I run Bioshock, 3 heatpipes on my 7600gt Ultra V1 gets very hot to the touch and they are being cooled by 1 low rpm 80mm fan :D

    BTW, i read somewhere that heatpipe can loose its cooling powers if too much heat applied to it

    Yeah, I can feel the heat on my 8600, I could feel it on my Arctic freezer pro, but I can't feel it on this damned thermaltake.

    That makes sence...I guess if I acctually was the one to cut them I would notice something like that. Was just goin off of what I remembered being posted. Thanks tho I did think it was "air" of some gassy derivation, and not liquid tho!

    It's what Poge said...mini phase change within a pipe. Carries the hot to cold, then the liquid condenses back to hot and etc. I don't think your supposed to feel it on the outside...because if you do that means it's not quite carrying the heat the way it's suppose to but dumping some on the outside of the heatpipe. I think...

    yeah the water woould just reach its point.. the guy who opened his added it to his water cooling loop so it had constant cooler water flowing through the pipes... it actually worked good! he used s zalman 9500.
