How to make TEC/Peltier

[trickson]

This is just an experiment and it could work or it couldn't but i will find out in the end

I hope it does . Could you please give some more pic's as to just how you are doing this . I have a 225w peltier and well if it works I want to try it .

All i need right now is some sort of block to put on the cold side.

I just told you a cold plate it will be the only way .

No you dont get what im saying. a water block like a VGA block. This one would work good

OH now I know what you are thinking , Yes you need a WB but a nigger one than normal would be better . Get a D-Tech V2 WB that should do the job well .

It has to have the barbs on the side instead of out the top. the backplate of my HS will be going on it to create pressure on it for better cooling

Anyone here own a CNC machine?

Andreoid might be able to help you out.

I would love a 40mm copper or aluminum block with two barbs on the outside!! i just used my Danger Den AM2 block and put some water in it and it froze in under 45 seconds

While I admire your efforts this will do very little if anything to actual water temps unless you use a very high wattage peltier.

Peltier coolers work because they have Direct contact to the IHS of the cpu block. The waterblock is on top of the peltier removing all of that heat from the hot side.

You problem is the heat will not be isolated, it will be flowing through the water system, meaning it will not stay long enough in the peltier block to achieve any cooling, or at least not noticeable.

A better solution would be to add a peltier to your reservior so more water can be cooled at one time. Or like some arctic fish tanks use, a peltier setup in the pump.

Or if you have a super low flow water system it may work but you will still need a very high wattage peltier.

Well if it works then its cool if not then i will put it on my old celeron and see how cold it gets!

Nice! Freeze the hell out a that celeron.

I was impressed with this peltier! it will freeze a waterblock full of water in less that 1 minute

The problem is that you have no water flowing into and out of the WB and when you do you will see little to no cooling of the water , IMO .

just for the coldplate thing you only need a coldplate if whatever the TEC sits on does not fully cover the TEC.

also for the flow thing like what has been said a single TEC really wont do much for temps this is why in my rig i am looking at several inline TEC's higher surface area so more heat should be transferred by the TEC's

 

[brandonwh64]

Ok got my temperature probe and did some tests and i was surprised!

Degrees in CEL

Degrees in F

Condensation

Almost got everything i need to continue my experiment. I only need two 3/8s barbs to finish!

I been reading along and I think I understand. The giant heat-sink is taking the heat from the peltier. The fan on the side is cool that...although I think another fan would be nice. The peltier is freezing the block the water travels thru to cool it. I understand where the other post is coming from. The water would have to be moving fairly slow the cool off to chilling temps. Or something thicker like anti-freeze would have to be used. A much larger waterblock (something like a tub) would probably work best. I can't believe I kinda understand this I give the OP mad props for doing this. Odds are, it's cooling better with it than without it.

The best way i have seen is make an Inline block that the water will run through before it hits the CPU. From the types of peltiers i have seen, they range from 10W all the way up to the 2k's

This is the best way to use it on water.
The thing is you want to Milk CoP on the TEC's as much as possible, to get efficiency.
The best way to do that is the get a lot of tec's and run them downvolted.
If you want even greater efficiency you get a pwm controller and have them run on pwm.

The thing about TEC's is they can handle rapid ons and off's unlike a compressor, and having them pulse like that would give you efficiency when your in idle situations.

Anyhow this is how my project went. I am still waiting for a good PWM controller so i never got around to finishing it.

lol any time someone says TEC chiller naekuh pops in with those pics! its great, question do you still use that chiller?? do you have any other pics than those same ones??? im seriously interested and want to see how its held up over the years

its still sitting on a shelf until i get a pwm controller.

but i did have it run.

It was doing nice numbers until i started seeing water slush in my tubing.

That wasnt a very nice sight either...

I didnt think it would pull the temp down that fast and quickly to be honest.
