Better than Direct Contact Heatpipes - Page 3

post #21 of 33
what if there were just more heatpipes and nothing in the middle no gaps then, polish them all together to a smooth surface. or just the existing ones were either bigger or flatter so they can be uniformly polished .

I also was under the impression that the heatsinks with the pipes on the bottom as opossed as the ones sandwhiched worked better already.

Actually what I would like to see is the heat pipes staggered as they go through the fins. I would imagine this would lead to better cooling than we currently see with either the True or Heat pipe coolers. Then again I could be way off. :Shrugs:

on my 5000+ i'm idling at 26c

why cant the only plate on the bottom be a thin hollow metal plate with pipes welded to the sides. They could prob forge the whole thing. Oh wait that's what duckieho thought of

And are the pipes filled with water or just air?

Personally I feel that the future of cpu coolers are going to be variants of the TEC coolers

First off the gaps are minimal... Secondly use a little extra thermal paste and they fill right up

I actually think i am gonna solder and to some tweaking to fill in the gaps anyway just to see if I yield a -2c difference
Gaps are mininum... but they still exist. Why do we lap? Because there is a gap... even though most ppl would call it minimum. Thermal paste is few hundred times less conductive than metal.

Also, adding solder wouldn't be as efficient since the heat has to go through CPU-solder interface, the solder, and then through the heatpipe-solder interface. A base acting as a heatpipe would only have the CPU-base interface.

Heat pipes are filled with a working fluid that changes to gas.

TEC won't ever be mainstream since they have to be tweaked to a specific system (as in the load, ambient, and cooling have to be known within a few degrees or it will be bad). Also, TEC draw much more power than other more common cooling.

Yeah you are right, Just you posting this thread made me think of ways I can already improve on my cooler... Id rather have a layer of solder filling in those gaps than thermal paste anyway

After some thought on this i kinda see what your getting at but why not just make the whole base part of the heatpipe? The only thing that whould make this difficult would be actually manufacturing it, i did a quick CAD render of an idea i had for this:


(note i could only be bothered to do 1 heatpipe lol)

But basically its just a machined out copper block filled with a heatpipe solution, The copper cylinders in the centre are to help convect heat around the block.

Yepper, I have an idea, but until I do the poor mans patent I ain't saying. My luck it's already been done, but I am actually thinking about making my one heat sink one and seeing how it works.

BTW Duckie thanks for getting me thinking.

The heatpipes won't work properly in that design. The gas pressure/temperature will be too high before the phase effect will work. Since there is no individual pipe, the heat transfer and cooling will be all types of messed up. There's no wicking effect and mounting direction will matter.

so basically what your saying is that the heatpipes have to be prismatic and constant, well so basically your idea is just making the heatpipes as part of the base?
