Waterblock with built in chiller..

[VashTheStampede]

I've had this idea stuck in my head for a few days now and I need some help developing it some more. We've used peltiers to cool down CPUs directly and kept the pelts cool with water. Then we moved along to waterchillers which was two waterblocks with a peltier sandwiched between them.

What I am aiming for is a mix of the two. The waterblock I am drawing up is to have copper pipes coming out of the sides which will have water circulating from one side of the block, back to the other side or something like that. The short of it is to have peltier(s) attached to those pipes. Since the area for cooling is very small, a small pelt would do the trick. Water would enter one barb, and flow from the barb to the left side of the block, dump out into copper pipe, get chilled by the pelt attached to it, and enter the right side of waterblock, flow through and leave through the other barb.

It would look something like this I guess:

Any suggestions or comments?

Ummm,

1. What's going to make the water flow?
2. If you're dealing with such a small surface area for cooling, won't you need a very powerful peltier?
3. How do you plan on getting rid of the heat from the peltier?

Sounds like a good ideal, but i cant see it being any better than a waterblock with a maze2 design(intake in the middle) and if you cool the water before it gets to the block it showed have the same effect(if you include the small pelt as another chiller).
still sounds interesting and is unique.
Another concern is it may be alittle bit to heavy for a motherboard, and you also have to think about space.
But if its used in a watercooling system that has a low water flow rate it should work alot better than just the inline chillers.
but this is only what i think:D

1. A pump. Well not just any pump, the pump that is still sitting in my soon to be resevoir, my parents old aquarium.

2. No. I always thought the way it worked is you used to the peltier formula that OC.com provided us where you factor in wattage of heat given off by the CPU. Well since there is no wattage of heat above the waterblock in the copper pipe, I feel a small pelt would do the trick. Just look at Coleman camping products, several of their products use small pelts to cool products much larger than what I am proposing.

3. The peltier to be used will be smaller than ones people put on P3s. So I believe the hot side can be passively cooled by a heatsink or ducted air or a combination of the two.

Im curious as to what kind of size are you talking about? Ive thought about something similar, just no pelt involved. And what size is the pump? If Im understanding you right, the pump goes into the water-block core right? That would have to be a pretty large size for a pump, unless you found a pump the size of a nickel... :p

LOL, no, I think I am being vastly misunderstood here. It's your standard watercooling setup with a resevoir. Just the waterblock will be different. It will be very similar to the MAZE2 but instead of one giant maze of channels, there will be two seperate ones, left maze and right maze. Only thing that connects the two is a copper pipe on the outside of the block, and that is where the peltier(s) will be.

So cool water leaves the heater core and enters the waterblock, flows through the left maze, enters the copper pipe, gets super cooled by the peltier(s), and enters the right maze, cools down the CPU even further, and exits out of the block and back into the resevoir.

Ok yup - I was way off!

why dont you make a waterblock 2"*2"*2" and then drill 4 holes like on a dice(the side with four dots) and slap a pelt and a normal heatsink on it and connect the holes so that the water starts in the bottom then goes to the top tunnel, goes back to the other bottom tunnel and back out the top remanding tunnel.
I would think this would be easier to construct and should get better temps.
