Why are most evaps so tall? The liquid can only phase change when in contact with the base plate and to a less extent fins, so does all that hieght really do anything?
In waterblocks all the significant heat transfer is with ~1-2 cm of the CPU core because thermal resistance, and I doubt evaporators are much different since they're made of the same copper. Is the idea to get the gas away from the base plate?
i am no expert but it is my understanding that with an evap you want as much space for the liquid to evaporate as possible, as the more liquid that evaporates, the more heat is taken away, and when you run out of room LxW, you start going up.
Heh, Im born and livnig in Chełm (Chelm - not use Polish sign), but I'am student in Warsaw :DQuote:

Want to build a simple evap? Dimentions as stated use a coarse thread tap for the inside surface..
THis is evap is licesensed to teh members to use at will. No commercial use permitted. THX.
http://www.blairwing.com/images/threadvap.jpg
hmm im having trouble understanding that chilly
Seems to me to be a block of copper with channels drilled through it. Use a tap and die set to make the jagged threads.
Something that has me is the part at the bottom. What are those?
cap tube and a u shaped piece of copper to connect the channels? And then... you plug the hole in the top of the drawing maybe? so uhhh cap tube and suction line are from the side if i am guessing right?
yes teh in and out are from the side. The holes are actually drilled and tapped for surface area and then either brass or copper is threaded into the holes and soldered in place. and for the suction a U tube can be drilled or 2 seperate fittings used.
Can you pls draw the way that the freon goes in that evaporator?
The freon gets in thru the bottom left U i beleive, or thru the right, suction being on opposite side. Check out the Freevap's... its getting interesting.
here's an easy evap i made out of a maze4 water block and caps from home depot:

http://img287.echo.cx/img287/595/minidirectdie6wb.jpg
Here is the inside of my evap. Cap tube goes in the centre, suction where that chunk of pipe is sitting in the picture. It is made for upright mobo's.
my friend made it for me, sth similar to chilly1 evap ;)

Alright alright, I'm very new at this so please bear with me if I sound a wee bit n00bish. I have been doing EXTENSIVE reading on phase change and other methods of xtreme cooling, but I still have questions. I know what the evaporator does, but how it does it is a different story. You have the cap tube going into it, and then the suction line comming from it. I read earlier in this thread about putting the cap tube within the suction tube. Meaning that there is only one tube showing that goes to the evap? Also, I'm not sure how some of those evaps work. There are some really sexy looking ones, looks like people put some serious time and effort into these! I really like the look of xooler's evap, it is quite nice looking. Just wondering if someone could hook me up with some knowledge on the subject. Like I said, I'm a n00b at this so there is no such thing as telling me something that is benign. Any advice will be greatly appreciated and heeded.
Thanks

(I'm down with making this a sticky as well) :toast:
probably also this would be simple to do with a press drill,you can have a serpentine in few time
http://img160.echo.cx/img160/9620/simpleevap3cb.jpg
after, you obliuvsly have to close its side;)
ah,that was only an example of how you can use that simple way of drillin,perpenducular drilling in a ruoted copper block
How do You guys get the evaps polished?
I dont get that type of shine with sand paper!!
Fine sandpaper and a lot of patience ;)
you need to lap flat then use progessivly smoother paper to about 1000 or 1200 grit then buff with buffing compond.
Mini guide for everyone who like mirror finish
That evap was done in about 10 min, quite fast. It depends how messy is base.
Evap base..
http://gorajec.net/raven/purecold/0.jpg
Evap base ater 4minutes with 800 paper, previous was ready in one minute but this was more messy.
http://gorajec.net/raven/purecold/800.jpg
1200.. about 1-2 minutes
http://gorajec.net/raven/purecold/1200.jpg
2000.. 2 minutes
http://gorajec.net/raven/purecold/2000.jpg
and here it is, a mirrormaker paste ^^
http://gorajec.net/raven/purecold/2000p.jpg
http://gorajec.net/raven/purecold/2000p1.jpg
after about 5 min you'll se sth like this
http://gorajec.net/raven/purecold/2000m.jpg
for better results just polish longer..
..for example i spent about 20 minutes polishing this evap

interesting idea, but how do you block the holes when the wall is at 45° to the hole?Quote:

raven, why do you bother in having a mirror finish with chemical products??
its unnecesary that you see yourself on the base of an evap, you need it to be just flat.
those mirro maker paste just add stuff to make cooper shine, but that stuff actually may harm the heat transfer when you use it.
i would just use the sanding paper, actually 2000 is more than enough. clean with some alcohol and you should be fine.
Hmmm yeah... I dunno if anythings happening with the free-vaps.
Because it looks good and its easier to clean, and you propably wont see any difference between polished and unpolished surface. Like you said, i think even 1200 sandpaper is enaugh.
Freevaps in the works we had a winner and I need machine tme to get them out..

chilly1 clone evap
Different channel size and cross drill suction added
http://www.geocities.com/kang_kemod/screwevap.jpg
^ that base is REALLY thin, how you planning on mounting it?
I like it, just cut the evap at half.Quote:

John.
^hows that work? i see holes on top and bottom... does suction come right through the block? or is the cap tube to be on the bottom holes with the freon ascending up the sprial?
Seems that is more like that...Quote:

So I have to drill a hole at the pipe, it'll make the evap not too pretty but it should work well I think. Manage to size 0.05 sqinch for oil return and good expansion space.
you could put a single end [cut dual end in half ] end mill bit in a drill press with a vice to hold the part [we have a drillpress vice that is like a 'milling table " so the part can be moved while it is on]
then you can make crap easier
Hmm, i'd be careful with the clone wording, chilly has a copyright on his blocks if I remember correctly:fact:
As far as I know, he doesn't mind people reproducing them, so long as it's for personal use, not commercial.Quote:
Originally Posted by aussie_guy00000

Legally there is nothing wrong with reproducing it all you want, as long as you don’t make money of of it.
I don't mind peeps cloning them. Non-commercial use is fine.. TO make the complete block and mounting in small quantities is more costly then buying one from me..
i just made one and i have it on my singel stage, no comercial at all.
Groovy, i'll get back in my box then :slap:
NO worries if you want help refining it of ideas on mounting what ever PM me.. I like to see everyone who wants to build them...Quote:

I don't really like multiple layer evaps. For heat to get to the second layer it already needs to take a long path. core->middle evap->sides of evap->layer of brazing->sides of second layer. The advantage of multi layer evaps is that you have some sort of an accumulator build in but I would try to make more surface area in the first layer.
very nice brazing and cleaning job btw!!
Nice evaps xooler, your brazing skills are amazing
I just dont like that kind of thick base, if you make it thinner you will get better results for sure.
Ssilencer
No,it's not my brazing skill :D
This Evaps was made on a Factory.
Evap's designed by Big_Sam.
Well as far as GPU's are concerned, they should work quite well.
The temps won't be as good as some of the solid designs, but with a base that thick, the temps shouldn't move much at all with the lower loads produced by a GPU.
I suppose that means that the OC should be quite consistent as the temps shouldn't vary all that much from idle to load.
Nice brazing and finish on those though. Says something about factory work :D I'd be interested to see how they perform.
But yeah, a little changing of the base to add surface area could only improve heat transfer for you :)

I had evaporators of more complex design, but I have refused their manufacture - too difficultly, and efficiency same as at those that above.

First unit (with SLi evaps on photo): http://steffbard.com/evaps/evap_001_new.pdf This unit works for me on two systems... on cascade with R404/R23... evap temps is about -95C on air, -85C without load on CPU (P4 6xx 1.75V/ 5.5ghz), -80C -78C loading... and in one-stage system with very short capillary tube :) on R410A... air -45C... without load -41C... -38C loading :)
Second unit...
http://steffbard.com/evaps/evaporator_base03.pdf
http://steffbard.com/evaps/evaporator02.pdf
http://steffbard.com/evaps/evaporator01.pdf
I have made only two copies and I established them on many various systems, now I already do not remember all, but results not on were much better than with the first unit.
Just had a look and they seem really good. The performance is quite good as well.
Only thing I'd think about is a u-bend from the compressor to the suction lines to prevent liquid floodback, but if they work, they work, so it's no big deal, but that's what I like to do.
The dual evap looks especially 'tight' and I like that :)
Nice work :toast:

Hello, I am debating on buying an evap or attempting to make one. Would it be possible to use a waterblock, I already have a swifty 6002 and was wondering if that would work ok? Thanks!
The bottem of a waterblock is to thin. 1-2 mm, evap has around 5-6 mm.
I was wondering the same thing as Fhqwhgads6680. The MCW6000/6002 appears to be a pretty robust design.Quote:

Looks good, How does it perform??
Blaster,
How the hell did you knurl the inside of your evaporator?!
Excellent, looks very nice :)
Tom
You drilled hole for cap tube ? What size of cap tube ?
Besides, really nice evap :)
dude that is sick.:toast:
did you do that your self??
yeah thats me on the lathe...
cap tube hole is for 0,7mm cap
more pics here
Maybe drill larger hole, for 6mm pipe...then, you could use cap tube, and maybe in future you will cut cap tube and will use cpev. Then you haven`t do new evap for cpev, but you will use this ;)Quote:

make some test with a tester and report back the rezults plsssssssss
double it with the same design evap but not those fins please!!!!

Me had liked to see all these evap for that this way me san wins in a future to make me an evap for the video card.
You could give me some idea of as making a block for the video card with copper 1 centimeter of width thickness it is 14 long centimetros,de I can make the measure that I like, I would like to make a block which also covers the memoirs. As you see making a block of these?
To forgive, you that you this speaking of another topic, but I have this great doubt, of if you can manufacture and it will be advisable.
Thank you
