Watercooled heatpipe CPU heatsink - Page 6

post #51 of 56
Why not just cut the heatpipes just short of the block, silver solder on connectors to form an input and output header. Then take your beheaded air cooled heatpipe radiator, solder on connectors to it as well, get yourself several hundred feet of tubing, throw in a pump between the return line and the block and you'll have yourself a redneck style closed loop. Next thing would be to bust open a water main, preferably one that runs steadily and you don't pay for, and jam your rad in so the water flows through the fins. I actually have though of this, I just can't find the city water shut off main so i can chop a hole in the 6 inch pipe and mount my rad and get the whole mess patched up before anybody 'official' catches me.

All our closed loop systems are based on the amazingly high specific heat of water but rely on air to remove the absorbed heat. I think you're on to something bro, we just need to find an endlessly flowing source of cold water to cool our rads.

I've just been pondering this - and so, found the thread.

I want to take my Zalman 9500, cut into a pipe, and water cool the heatsink.
The water will be cooled to below ambient with an evaporative tower with water on the 20' coiled up copper tube and an office fan blowing on it.

God that sounds like fun.

Honestly, I think the best way to implement one or more HSF into a loop would be in combination with peltiers and a large copper reservoir. I have been wanting to do something like this for a while, and I actually saw where someone attempted something similar, but even then the results weren't great. Granted, they used a plastic res with copper finned server heats inks as the water contact surface, but it is a bit dissuasive...

I guess with a professional approach : right type of heatsink, right amount and type of heatpipes and a proper connection of the hot end of the heatpipes to the watercooling loop you could go to sub ambient temperatures... but wont come cheap biggrin.gif

High Performance (Water Cooled) Heat-pipe Heat Exchanger Here a clustered array of Heat-pipes are used in a high temperature gas flow manifold where over 5 kW of heat energy is transferred to cooling water,

Just to show these aint toys tongue.gif

Having said that it would still take up a "bit" more space than just a normal waterblock. "Just" a normal waterblock with an added vapor chamber (im thinking of these 2mm thick chambers - not a giant monster heatpipe) might be the first step to increase watercooling loops performance. Something around 20% : like with graphics cards vapor chambers. Its just that the watercooling market is a still not as big as the aircooling market but i guess its just a matter of time until we will see the first mass produced vapor chamber waterblock.

* effiency is below par - too many transfer losses

* the HS "toy" heatpipes are not designed for that

* cutiing into a heatpipe renders it useless

* HS "surface" is too small + the restriction it poses in an afforable loop is too high
(+ HS blades tend to be ALU - something you dont want to mix into your loop)

* Direct die water coolin is more efficient as a Waterblock IF AND ONLY IF the die is large , much larger as the current ones - minimal size before direct die becomes efficient is minimal GPU chip

While the idea is compelling , a little research will tell why it cant work in an affordable diy setup...... but yeah, keep thinking out of the box smile.gif


finally: Watercooling Myth #2 : ThermalTake = WaterCooling
