Unless you've got a particularly specialist application, you may well be better off buying one from a company who already make them. Link to one such company in the UK at the bottom of this post (google will have more - I just had that link to hand as I was toying with using one to cool the NBridge on a potential NF4 SLI system)

Odd, I couldn't find anything that looked promising in a quick look through google either. Still, heat pipes are fairly light so the UK one will probably ship them fairly happily, although you'd get stung by the current price of the dollar

I also found very little info, but limited Googling.

You'll be experimenting, from the looks of it... (Good Luck!)

I'll let you know if I come across something usefull; I also need it for another project.

actually, you can do it. at least if you have enough equipment...
benchtest.com
Heat pipe1
HP2
HP2.2

edit: Maybe try TTIC, they produce HP heatsinks sold under different brands.

Thanks lukr; that's all the links I had

I use flourinert FC87. or Novec hfe7000 fluid (3M) they boil at 30-34 C. Although you could use acetone (boils at 57C.) as a cheaper solution.

I bring the fluid up to boiling temp using a film heater (OMEGA) until I see a steady stream of vapor coming out the top. This is called out gassing and will provide best performance.

once you have a steady stream of vapor cap it(screw on?) then let it cool down.

In most cases a couple of thimblefulls of fluid is all you need. you have to make allowance for boil off during the outgassing .

you can use cotton or steel wool (000 fine) for a wick , ,my choice these days is copper wool
