Question. What's the difference between those blocks other than their interior? Are those designs specifically made to optimize cooling?

[Unseen]

Seems like you are going for as much posts as possible, why didn't you put the photo's in one or two posts?

i want the pics to be stored in xs disks. Not in another server.
Plus i can only upload 5pics per post.

how it works???

[JSU]

goes from the bottom up, if you notice the disks arent 100% aligned. That is so the refrigerant can flow through.

Hawainpandas block no.1

[Aphex_Tom_9]

^ not too shabby, just that thin wall scares me...

[gclg2000]

As long as you don't torch through the wall its fine. When i brazed it shut, it never got even close to burning up...The metal is lieterally touching the insde chambers (within a few thousands of an inch), so the heat just spreads and spreads throughout the whole block. It can withstand plenty of pressure too :banana:
:toast:

Click here (http://www.namike.com/albums/album02/MVC_007F_002.jpg) and you can see the cap tube inside the tube.

[gkiing]

Well the walls of copper pipes are only 0.032 thick or something, so I'd imagein it would be fine, but it would be better in copper either way (i think thats brass isint it?).

[reject]

yes i think its brass
maybe HP can enlighten us?
but chilly1 has tried brass and said that at the temps of DD/ cascade the difference between copper/brass is crap all

Should you give more informations about torch :) Cost of torch, oxygen bottle etc.

I'm planning to buy torch like you, but firstly I must buy oxygene bottle, which is a little
expensive for me..

Grotesque is always for me a negative thing

[Unknown_road]

oxy bottle is 10Liter and cost me about 150 euro. I bought everything seperate and don't know all the costs anymore.

what don't you like about my evap?

You can rent a 10l bottle for 30€ for a year here, if the bottle is empty you can change it for a full bottle with any gas you want (only have to pay the gas price). So renting is an opinion too.

Unknown_road, I'm not saying about your evaporator. I'm saying about photo. Only
this photo makes me grotesque feelings, not evaporator :)

[gkiing]

Looks good, but all that extra copper will make it pretty heavy. On the other hand the extra mass may enable it to hold its own against a higher load.

[LardArse]

I love this thread. I wish it had the pics from the evap gallery thread from www.phase-change.com
So many beautiful and innovative evaps!

i have seen yesterday a "trapano a colonna" donno english :(, like the one that you use shamino) for 49€....i think i will buy it....49€ and i can make all the evaps i need :D

"trapano a colonna" is that a "drill press."
what you use to drill lots of holes in a copper block to make an evap?? :toast:

[kayl]

when it comes to torches ppl really underestimate the map gas torch.
that is really all you need, and maybe gas camping oven. i do evaps on low map gas setting.
i would hate to have to pay for oxygen the way i braze.
map gas last foreva.
you would be suprised the ampunt of ppl that use it.

[hatemi]

Today I went to the shop to get more brazing ros and ended upp with 1kg of 2% PhosCo and this:
http://www.primus.fi/www/popupcard.php?id=221

It uses a gas mixture of Propane Butane Propene and Acetone so it is more powerfull than the regular propane+butane torches. Very handy and brazed 5/8 tubes with ease:) I'm pretty sure it is equalent to MAPP in preformance. The set cost me 130 wich is kinda much byut not if you compare it to oxy/acetylene setup costing 1500€

i know, but here in italy i cannot find toeches for less than 100+€ :(

[hatemi]

The torch I posted above works like a charm and you can propably find one in italy for a less than what I paid for. Just make sure it has the ultra gas botle and not the power gas one. the powergas is regular propane+butane one and the torch tip is smaler and less powerfull than in this torch. you can find it either under Primus or Sievert brand name:)

[Malachia]

i found mapp bottles @3€, the prblem is the torch!

[Epsilon]

I have more torches here. I have a oxy/propane set (Gloor lilliput) of very high quality, I use this one for brazing. Mainly because it is much quicker than a non-oxy flame and smaller (so easier to handle)

I have 10 euro hand propane torch (with expendable propane containers). I bought it for soft soldering, but now i use it for extra heating when brazing evaps (to safe the much more expensive oxygen).

And a swirl flame propane torch. This one has a 2000c flame with a 21mm diameter. This is more than enough to braze pipes together, but i use my oxy/propane torch for this. Now this torch is used as pre-heater and extra heat sorce when brazing very large things.

I can get a oxy refill for about 20 euro (10Liter) so that not to bad. The price of buying an oxy cilinder is high but once you have one your in bussiness :p:

I have two of these for making an SLI phase-change system.
Anyone has pics of this evap brazed with suction and cap line?

One of my evaps is brazed like this and the other is still unbrazed:
http://clientes.netvisao.pt/ratax/RataxKryo/eva_brazed1.JPG

Do you think it's like this?
I know that it's better to have the cap line in the center, but with this design, that's the way I think it's mean to be used...

[Epsilon]

lol no

see the little hole in the middle ?
it should go through there (from within the suction line)

[Ratax]

lol no

see the little hole in the middle ?
it should go through there (from within the suction line)

I don't understand... and what about the access in the corner?
If I put the cap line in the middle, within the suction line, how will the gas flow if the corner get's closed with the top?
I mean, with the top on, the hole in the corner (in the center piece) doesn't have conection (in the top side) with the other chamber, were you say to put the cap line within the suction line...

looks good, but it might be too restrictive. Also make the whole thing taller and it will hold better temps due to the larger mass.

[Unknown_road]

it's not too restrictive I think, it is a bit large tough, dabit had some issues with the size(width*length). I would try to make it smaller. making it a bit taller is an option indeed.

width and height wise, it fits great.. just need to eliminate the p4 holes.. Im thinking about making it taller.

[gkiing]

Making the channels taller would greatly increase the surface area.

Man, its a shame the braze job looks so bad... Oterwise I'd give it a 10 :p:

Its made on a CNC yepp, and about the brazing, I havent used any "sandpaper" or anything on it when I took that picture, it looks alot better now (and its insulated to) having some difficulties with the insulation thou, alot OT from me now. The system is pressure tested and everything seems ok so far ;)

edited by runmc :nono:

[saratoga]

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?

[Revv23]

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.

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

[Revv23]

hmm im having trouble understanding that chilly

[smurfmods]

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?

[Revv23]

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?

[chilly1]

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.

[GoriLLakoS]

Can you pls draw the way that the freon goes in that evaporator?

[n00b 0f l337]

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.

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:

[gloatlizard]

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;)

[gloatlizard]

ah,that was only an example of how you can use that simple way of drillin,perpenducular drilling in a ruoted copper block

[the_new_guy]

How do You guys get the evaps polished?

I dont get that type of shine with sand paper!!

[alexio]

Fine sandpaper and a lot of patience ;)

[wdrzal]

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/2000p1.jpg

after about 5 min you'll se sth like this

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?





btw - what ever happened to the FREEVAP compo winner? n00b? chilly1? fugger?

[Coyote]

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.

[n00b 0f l337]

Hmmm yeah... I dunno if anythings happening with the free-vaps.

[RaVeN155]

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.

hello my friend:D we see to try them before possible:D:D:D:D::D veri nice;)
it waits for that I must to you telefon:D

I like it, just cut the evap at half.

[pythagoras]

No need to cut it in half, just think of it as an evap and accumullator combined into one ;)

Regards

[Revv23]

^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?

[Ratax]

or is the cap tube to be on the bottom holes with the freon ascending up the sprial?

Seems that is more like that...

[kemod]

I fail to make the channel larger (broke too many chisel) so i can put the capillary in it.
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.

[[486]]

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

As far as I know, he doesn't mind people reproducing them, so long as it's for personal use, not commercial.

[chefnr1]

it aint the same size and as far as i know theres posts earlier that says Chilly clone and he doesent say anything that i've seen about it...

[epion2985]

Legally there is nothing wrong with reproducing it all you want, as long as you don’t make money of of it.

[chilly1]

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..

[chefnr1]

i just made one and i have it on my singel stage, no comercial at all.

On that note, my brazing torch ate through the copper cap you provided because I spent too long trying to heat it up for the crappy solder. What size should I get for thickness?

[chilly1]

heat from the bottom... and then when it is real hot turn the torch down and just touch it enough to melt teh solder in front of teh flame..

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!!

[Ssilencer]

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.

[xooler]

Ssilencer
No,it's not my brazing skill :D
This Evaps was made on a Factory.
Evap's designed by Big_Sam.

[Gray Mole]

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 :)

[Big_Sam]

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

[Big_Sam]

What's the spec of the 2 units, and what kind of temps under load are you getting?

Gray


I have only sketches, it is complex for naming drawings...
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.

[Gray Mole]

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:

[Fhqwhgads6680]

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!

[Comp-Freak]

The bottem of a waterblock is to thin. 1-2 mm, evap has around 5-6 mm.

[Rockhammer]

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.

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

Wow, that`s very nice. Suction is solid with evap ?

[MaxxxRacer]

I think that is actaully the cap tube. notice the large opening at the top of the block. I believe that the suction line will be brazed to that, having the cap line inside of the suction line.

[epion2985]

lol, that is the suction line, or the begining of it anyway, then the flex line will be brazed on to it to continue it. I dont know about the capillary being inside though, I think it has been extablished that coiling it around the outside of the suction line reaps better results since even though its not as cold outside you get the whole line cooled rather then just a part of it when it is inside.

[jinu117]

Cap being inside works eqaully as good... :P Besides, who said you can wrap rest of cap outside once it comes out :)

[Ssilencer]

Wow, that`s very nice. Suction is solid with evap ?
that is for braze a bigger piece of cap tube there, then you can braze the cap tube you want and send it inside or outside the suction hose, you can see how it looks in this pic

http://img130.imageshack.us/img130/5426/ma1rev2051w0lo6qg.jpg
the idea is to make it easier to change or even braze the cap tube.
he suction hose has to be brazed on the top of the evap
the evap has an upper chamber.
And yes, is all one piece.

Also LukeXE see the size compared with a cigarrette, if that was to braze the suction line hose, it has to be some weird little thin flex hose :)

new cascade evap and his litle brother for singles, its the rev 4 :)

base will still be machined to 2,5mm after soldering

the small one is 3cms tall, cap tube is brazed to mid where there is a 5mm diameter hole from top to base. 4 holes in base provide refrigerant to spiral that is 2x12mm wide

spiral doesnt look 2mm wide cause when machining to final diameter it creates an edge that im not removing

like always all is done by me, from lathe to brazing jejejej

[tim-]

I'm currently building my evap, not finished yet but before I finishing it, I want to know what you think about the design.

sadly I havn't access to a lathe anymore 'cause my old friend have sold it.
But I still have my own miller at home.
I attach a image of the design, hope you understand.

http://goto.glocalnet.net/timedlund/Untitled-1.jpg

what do you think about the design? should it work proper?
chanals is 5mm wide, ports between inner/outer ring is 8mm (8*5 between the two lower "stages").
5mm holes in the top stage, and 3/8" out for suctionline, capilary tube goes inside the suction and spray liquid r404 in the bototm.

[jinu117]

It probably will work quite decent. Basically bit more advance than Baker's evap from looks. However, bit more distance in bottom plate will help most likely as I see very short amount of time liquid travels in bottom of evap.

[Unknown_road]

the only thing all those layers do is make it harder to build and more expensive.

Surface area should be in the solid piece that has contact with the cpu.

[Quasi]

My layman's opinion is that adding layers is adding barriers, or imperfect conduction, between the cpu and the upper part of the evap. More layers also equals more brazing = more chance for leak. More layers = more expensive.

The evaps job is to move as much heat from the cpu into the refrigerant as possible - I think one peice units do that most effectively as there are no added thermal barriers (imperfect,limited or very minimal contact between layers can occur). When I'm thinking about design - I like to think about "when the refrigerant gets to this point - how does this point conduct back to the heat source - what path must the heat take?" Does that make sense? While balancing volume, mass, and surface area is important - if you have layers then you have to add thermal barriers in there as an added consideration.

Chilly's evaps, and other steppers in sleeves, have to conduct from the plate and back to the massive center column and down (thats backward really - but you get the idea) no stops - just pure copper all the way. In layer designs - imperfect contact between them might mean the only way to conduct is out to the outer edge and down - and then through layers of brazing - just doesn't seem as good as the solid design.

If the brazing were perfect and the conductivity between layers acting as though they were one piece of copper - then I think its a great design.

But - I'm not an expert on evaps - I don't even play one on TV.

This is my first design - should have the prototype in about a week.

It's a bit expensive because its a little more complicated than a stepper.

Another I'm working on is based on Eleven's evap.

Any reason it isn't an effective design?

well, the price of making it doesn't matter 'cause I produce it myself.

but the lost of friends lathe make it difficult to make a solid evap.

I have pretty good miller so the evap parts will fit perfect on less then a 0,01mm differens.

[edit]
by the way I have to reconstruct the evap 'cause I'm going to use cpev, the capilary tube isn't going thought the suctionline then.

quasi, i like your design. mind if i give it a try in the near future while im trying other designs? i dont think i will make one exactly like pictured, i would modify it some to simplify machining (all my work is done manually)

[ilkkahy]

Evaporator should have good heat conduction channels to large surface area which should be NOT shining smooth. Ive read from some cold machinery book that rough surface area can be multiple times effective in case of boiling than same size surface which is shining (i think that cross-like Dimas? evaporator might be somewhat decent if it had roughened surface because otherwise it conducts heat well).

Most evaporators are just trying to be different and are more like visual shows than actually have some desingn in these aspects (multiple layer evaporators for example).

Some kind simple of pin-type block with directed refrigant flow channels might do the job nicely.

Just piece of my mind.. Im hoping DetroitAc will remove some myths about the subject some day with his testing system. Seems very promising this far.

well, this is an ideia to mix maze and steep.

DetroitAC has done some great work building that steady state calorimeter. That will stop all the guessing and conjecture and assign a actual value. I have a feeling there going to be some surprises :) . I also have a feeling there going to be a explosion in new designs,the great thing his testing will show if a design is moving the performance in the right or wrong direction. :woot: :toast:


Ps: detroitac ,I seen your evap kits did you think of offering one a t a slightly lower price and leave the drilling of holes or slots and the brazing up to the customer. If anyone is untested,I sure someone will want his own unique flow pattern.

In any case your work WILL move evap design forward. :clap: :clap: :clap:

|RickY| your evap looks great ;)

thanks

By the way: here is one evaporator which i made pretty long time ago for compressor setup which i never finished really :wth:

Seems that ive lost the best pictures where its finished but youll get the idea.

[DetroitAC]

Thanks for the encouraging words guys :toast:

I was thinking pins also ikkahy, this is one concept evap I'll test that is 72 rods perpendicular to the flow direction, four passes, with an increasing cross sectional area. As you can see I didn't plan for the size of my suction tube very well and lost one rod. I don't like the thin blocker plates on this, I'll never do that again, and this one took a really long time to build...but you know, it's just a one-off concept.

The bottom part is missing in those pics or have i understood wrongly? If that big piece is meant to be bottom im not sure if the refrigant flows that well in those holes.

Very nice machine work anyways. I wish i had mill at my usage.

[DetroitAC]

The small piece (with the thin plates sticking out) is the base. It has short holes drilled in to hold the rods in place. The big piece has holes that go through, and the rods were inserted with the two pieces assembled. The base was made extra thick so I can mill it down in between tests to (try to) find the optimum base thickness.

[ilkkahy]

Hmm.. that was unexpected. You want to use pins for creating turbulence? I dont see the benefit from their surface area unless they are well "thermally connected" to cpu.

DetroitAc: would you happen to be intrested in realizating evaporator if i desinged something special with care? I pretty much know what kind of constructions are possible, too hard or just impossible to make with basic machinery.

[DetroitAC]

They are inserted into and then brazed to the base, so yes directly thermal conduction to the base, and added turbulence and conduction area. PM me with your idea ilkkahy

the small one is 10mm high :)
made for NB or GPU
easy to braze
costs less than 10€

[LittleDevil]

Nice evap, but are you purging while brazing? Do you have mounting for it?

thanks

[Moc]

lol, thats exactly what my german people asked me. :p:
No, i didn't purge them but the next I will! :)
For the mounting, I need plastic like you use for your mounting but I dont know where I get it local... :(
Do you sell mountings for GPU evaps? My Evap has 28mm diameter.

[LittleDevil]

Every evap has different mounting, i can make it if you send me evap, but on your i don't see any groove for oring or something like that...

thanks

[ilkkahy]

Here is one basic principle of channel type evaporator that i think might be pretty damn effective. The idea is pretty simple but if the channels were threaded it would have plenty of surface area and very good heat conducting properties. The edges would require accurate milling but i think it might be worth trying. Suction and refrigant channels would come to evaporator from the edge plates that arent seen in the picture.. i just got that 3d program today so i didnt bother to draw them yet :D
