View Full Version : Electric stove made copper block. H2O cooling made EASY.

Today I made my H2O block from two pieces of copper and some ratshack silver bearing solder that melts at a very low temp but still high enough for this I guess.
What I did was take two plates of copper and with one of them I routed my channels through them. The other one I sanded down flat as also the channled one two. I then got some of that paste solder that rat shack sells and it says you can melt it with a match or lighter. Well I decided to try it on my stove. It appeared that my stove was indeed just the right temp and then some to melt the solder. The solder paste already has the flux in it and when heated on the stove it made a perfect joint and when cooled it was perfect with no holes or bubbles through it. Now all I have to do is attach the aluminum plate on top and away I will go. Should know soon enough how it will work with my coolant chiller. I got the idea from Bladerunner here

http://discussions.hardwarecentral.com/Forum11/HTML/017053.html

It worked very well and in about 5 minutes time I had the plates soldered together.

Now I have to drill and tap 4 holes through the block in the bottom plate which will hold down the aluminum top plate which is very thick cause this is going to cryo cooled I am going to need a very steady middle post to hole the whole thing down on the cpu. I will then use a hex nut and tighten going upwith the nut and it will pull the whole thing together Below the nut will be some insulation so the block does not sweat all over the tualatin goodness that has graced my presence. I will also need a small amount of insulation under the mobo too and under the chip and maybe on the mobo around it.


You can kinda see how good my seal is. When I had this on the electric stove it hit a certain point and then the top copper plate was floating on the liquid solder. It was at this point that I pressed down slightly on the top copper plate to insure no bubbles or holes were present in the solder and then I shut the stove down. After 5 min I put the block under the faucet with pliers and walla. Now I just have to as I said above drill and tap the block so I can attach the aluminum cover and put the barbed fittings in it.

Here is the end result of soldering the two plates together.

Nice.. How did you cut into the copper sheet? the middle Im presuming? So theres 3 sheets in there? top middle and bottom right? and the middle has the core cut out... for the water flow?... very interesting idea... all done on the stove... hhmmm...... wonder if our local crap hardware store has stuff like that.....:eh?:

Radio shack is where I got it. I forget the price though.

I used first a drill and drilled out as much as I could. I then used a grinder and jig saw to do the rest. It was not that hard.

Why an Al top plate, surely Cu would be better.

Why? I am cryo cooling my setup and I need a long post mounted in the middle of the top of the block as to allow insulation under it. Here is a pic of what the middle post will look like tapped and screwed into the aluminum. I would fear with a thinner copper top I would not get deep enough. With this thick aluminum cap I can get it deep enough.

I got a stove in the kitchen too! Will try it as soon as you send some copper over to my kitchen!:D

I got the parts for this for $10 local. Send me the cash and I will get it for you. You don;t have a place there that has copper plate? I only have one place in town.

Have to remember this for future projects. Thank you.

how are you going to attach the aluminum to the copper?

I made four threaded holes like this bottom pic and used a sealant in between it and the copper block. I am testing it right now and it is holding. I will run it like this for a couple days before calling it good.

Ah well that's life...

Well I got the above block on my coolant chiller here at the bottom and the temps of the coolant are -20 deg. C. The block has been running for about 3 hours now without a problem. Pump was $14 and runs aorund 500GPH.

That "sandwich" looks like it will work. You have to be careful that you don't use too much solder and have it melt and run inside, then it might block your passages. If you need small amounts of metal a good place online is Online Metals. They sell small pieces. Here is a link.

Not usre if you could see but the solder was perfect. It didn't go any further really than it was supposed to. Thanks for the concern though. I have it running right now in my chiller still from last night. I took a bowl of hot tap water and put the block with coolant running through it in the bowl and it cooled the bowl down in about 3 minutes to room temp. i then went to touch the block and the water was already frozen too it. I think with this setup I will keep my chip cold enough:D I figure -10~-20 deg. C.

Think that should do it?

Thanks MW521. I've been looking for a place to purchase small quantities as well. Can't seem to find it locally.
