so i just decided 2 go balls deep n2 water cooling and ordered tons of stuff that i didn't need, sold some and ordered more. anyways, now i got 10 45w TEC's offa ebay just 2 c what they were about and do some prelim testing on them.

at 12v and a heatsink and fan on the hot side, the cold side drops 2 around -3°C and the hot side is around around 38°C. that's with an ambient of around 24°C. fun stuff so far.

well now i've made a few drawings of a (possibly bay mounted) TEC water chiller... here's some pics:

this is the layout drawing. on top and bottom r the aluminum heatsinks i'm gonna make. middle is the copper "water block" and n between r the TEC's.


... and a 3d view.


i currently have 2 TFC 360 X-Changer rads and a cpu, nb and sb, and OCZ flex II water blocks. i'm gonna get vid card blocks when i decide what gpu's 2 get and mosfet/volt reg blocks when i decide what mobo 2 upgrade 2.

i'm basically gonna loop a few components 2gether out 2 a rad, then back n2 a few more components and then back out 2 a rad and then 2 this water chiller or something similar depending on what happens n test phase.

right now my water temps with a cpu only loop get up 2 30°C, how well would u think this cooler will work if i used the shown 10 TEC's or maybe only 8?

Your dimensions are ridiculous. Did you do the drawing in metric then forget to change your dimension settings? I would really like to see plastic being made down to the #/32 lol.

whadaya mean by rediculous?

no, i'm just a lil anal when it comes 2 things being even and what not. and sometimes i have 2 do things at work that need 2 b within a few thousandths tolerance.

what a lame stupid comment

so does any1 have any idea about how well it would perform with 10 or 8 45w TEC's?

eRazorzEDGE

well, since i can tell there's hella ppl interested n my thread ( ) i decided 2 post more pics, yay

got 2 work on the build this week. cut out all the pieces earlier this week and to day started 2 put them together. any1 else like working with free copper?

heres the parts that i cleaned and an extra piece that i halfway cleaned so u can c the b4 and after...


all the shiny pieces b4 putting them together


was playin around with welding... never welded copper b4. this was a fuse pass on AC...


on right is AC pass, on left is DC pass... i'm thinkin the DC looks cleaner


here's a shot of the internal passageways, if u look at the drawing as reference, this pic is of it on its side...


shot from the other side. u can c how the water will move through each quadrant...


hopefully more to come real soon. any comments?

Nice work- Subscribed. Keep up the pictures!

finished building the copper chiller today; now on 2 the pics...

here's a few of the sides being put on...




this is a test piece of 3 .0625 copper sheets sandwiched and welded together, then drilled and tapped. it would've been nice if i had some 1/8th inch copper plate, but i didn't


right b4 this pic was taken, i realized that i should've punch and tapped the holes BEFORE i put this piece on...



shots after i drilled and tapped the holes (and the holes were actually straight! ) and started puttin the rest together...




the final product...





the best thing about welding copper is that the whole piece gets hot so fast that it doesn't warp around wherever u welded like other metals. but now it's on 2 making the aluminum heatsinks out of some nice 6"x6" solid square blocks

That looks awesome. I hope it works. You might want to PM martin becase he made a TEC chiller for some guy over at XS or something. You are probably going to need some serious airflow over those heatsinks to get the other side cold enough to make a real difference. From most of the ones I have seen people tend to use water on both sides. If the thing is not closed up yet you might want to add some more surface area to the side that will be in contact with the tecs. If it is already closed then I say get it working and do revisions later. Really neat project though and I haven't seen anyon weld copper so thats pretty cool. subscribed.

thanx 4 the comments. yeah, the copper box is all welded up, and i pressure tested it this weekend (i have pics but my comp is down ... that's n another thread) and no leaks. i haven't worked with electronics n over 10 years, so my biggest problem right now is how exactly to hookup the TEC's 2 the PSU and exactly which connectors r attached 2 which 12v rails.

updates and more pics will follow shortly.
