Homemade inline Chiller Idea......

[joshiieeii]

ok, having gotten pretty good results with regular water cooling, I was thinking of getting a pelt and see what I could do with it. But I understand you have to waterproof your stuff due to condensation.

Well I was thinking... (dangerous, I know :eek: ) and I have read some threads where people have had pretty good luck with chilling the water instead of pelting their CPU. So I came up with this idea, I haven't seen it here before so it might be old news. What if you made a copper heatsink like waterblock with a honeycomb type pattern, attach a pelt to it, then strap a heatsink on the other side?? see pic below: (made it real quick on paint)

I was thinking of just getting the water as cold as ambient or a little below, no sub zero temps.

Has anyone seen anything like this??

Or know of anyone that has tried something similar??

Where does the cpu go in that picture?

Yeah, i'm running one right now, actually, but inside my resevoir. Here's a pic of what it looks like, but it hasn't improved temps very much. It will keep the temp from rising too fast, but not much more than that. I'm only using an 80Watt pelt, though, and both aluminum heatsinks.

Here's (http://forums.overclockers.ws/vb/showthread.php?s=&threadid=37021) the thread.

This is part of the water cooling system, it could go "inline" either before the processor or before the resevoir.

Like this:

I'd stick it between the radiator and cpu, with the water going from radiator to cpu.

I would think it would work, too. Probably need a fan on the hs, didn't notice one in your other picture.

Thelemac, you're right. The chiller should go between the radiator and the CPU.
Besides, if it is possible to use a chiller this must be the way. It would be wrong to place the chiller in the reservoir. The contact area of the heatsink is way to small compared to the volume of water in the reservoir. You would need additional ways of circulating the water in the reservoir through the chiller's sink!

Another idea is to attach a water chiller to the pump so that when the water recycles it is immediatly cooled back to a specific temp..

At a pub I used to work at the chillers could cool to just over 0C..
Say +0.5C although you may not see a large difference between 1C and 0.5C!

Wow man! That I have to try! (with the radiator right "before" the pump/reservoir)

You know, maybe a stupid idea but would it be possible to bend a tec to attach it to a metal tube, instead of the traditional coldplate?
I remember some writing in the watercooling tips from someone who made an alternative reservoir for his EHEIM pump.
*http://www.overclockers.com/tips209/*
If you could make a comparable reservoir but out of metal tubing, and attach a pelt straight on this metal reservoir (maybe with some cooling fins inside................ . . . . . . . .
Got to go, I have stuff to try :D

Why would you do that? So that the water doesn't go below ambient?? If so that is a genius!!:cool: *edit* BTW, heh, the black thing was supposed to be the fan :).

Is this what you are talking about??

Are you referring to Fuzzball's system or mine? If you look at the first system pic I posted, the chiller is directly after the pump.(My pump is submersible, its in the resevoir :D )

[fuzzba11]

I have a 92mm high output Panaflow fan on the hot side, now, and it still gets *really* hot! If I were you I would put the radiator on one side of the CPU, and the chiller on the other side to keep the water temp stable.

Actually, that's exactly what I was talking about...but I think you have the flow going oposite the way I think it should. I say that because that way you have the radiator cool the coolant to ambient and then cool it past that with the chiller...thereby giving you really cold coolant. :)

If you're going the otherway it would probably be easier and cheaper for you to get another radiator or something.

[nihili]

The chiller has to go between the radiator output and the water block. Ideally you want it to be right before the water hits the water block.

If you put the chiller on the inlet side of the radiator then all you accomplish is a reduction in teh efficiency of your radiator. You won't actually see much cooling.

correct me if Im wrong I like the idea but dont you need a very big HS on the hot side of the TEC?

I remember someone said that the pelt will burn out if you dont have it cooled enough

Im thinking about adding this feature to my cooling just to test it

I was also thinking about water cooling the TEC so you can get the cold side even colder and like every one said you have to put the chiller right before the cpu to take afect

thin I read this (http://www.procooling.com/articles/html/kev_explores_pelt_water_chille.shtml) at procooling......


and that just made me depressed:(

Well I was hoping the Stock HS off my T-bird with the help of a good fan would be enough to cool the TEC *shrugs* How many watts does a 1.33 Ghz Tbirdy put out?

I fixed the pic first system pic above, is that what you mean by puting the chiller before the CPU?? (BTW that is how my flow goes now anyway, just didn't notate it :D )

[Warlord2]

Im thinking that you would have better results because a heatsink has more surface area thin the one procooling is using

:rolleyes:

I was looking at that setup, and it seems to me that if the water was moving slower, then it would have time to release some of the heat. Possibly use a smaller pump or a flow restrictor?

*KLowd opens that can of worms* :eek: :eek: :D :D hehe

There is soo much controversy over this. I have a Rio 800 (200Gph??) anyway, it has a pretty good flow through my system.

Alright, I would now agree with the procooling article, the chiller is a little worthless...you won't cool your temps very much unless you have water that is above 23 C, at least. That's what I've found. What it does do, it cools the water that comes into the resevoir from the CPU, since putting it inside the resevoir instead of inline, the water stays next to the chiller for longer. So my design is superior! :D

But seriously, if you do build one, I would make it have nice and high heatsinks on either side, and they should be identical, too. Then position your water so that it flows in the top of the resevoir near where the chiller sits, at the surface, and is cooled, slightly, before re-entering the pipes. It would work really well in pre-cooling your water, while your system isn't running, but unless you have an extra PSU for the pelt/fan you can't do that without disconnecting/reconnecting the motherboard everytime you want to start up/shut down.

Feel free to try do a better job, if you feel so inclined and have the cash, but I think investing the same amount of money in a radiator is a better idea. Personally I've decided to go bong and try find a way to use the chiller in that system. Happy cooling...

why don't u go to electronic grave and try to find fridge chiller then u can make a chiller system for your compie with less less money.

Umm... :rolleyes: You mean I should kill my puter are it will ressurect into a fridge?? :eek: Where is electronics grave?? heh :cool: How much is less less money??;)
