Take a look my new single stage project... (56k not friendly)

[Unseen]

.

[Unseen]

another one...

[Unseen]

i will use it for my vga...

[Unseen]

i put a candle to see if it can handle some load...

[Unseen]

this is after 30 min...

[Unseen]

it is an embraco 1/5 filled with r507c and 3,20m .71mm capilary and a custom evaporator....

first i need to now a way to put it in my vga
and second a good-cheap thermometer to buy from europe...

thanks..

[JSU]

good job! a good way to mount it is get a piece of 1/4in plexi glass and drill a area in the center of is where your suction line goes then dill holes in it and use machine screw + nuts to attach it. srry for the bad description its a bit hard. Ill post a link in a little while.

btw what kind of hose are you using?

[JSU]

http://www.vr-zone.com/?i=714&s=13

[Unseen]

it is a simple hose that we use in gauges... but i braze it...

[JSU]

um i hear that those leak eventualy and you cant use them....

[Unseen]

on the other system it didnt leaked yet...

ps. sorry for my bad english...

[kayl]

nice
i like the evap that looks like a good weight not too much pressure on the gpu card to warp it

[Unseen]

here it is how it looks from inside...

[afireinside]

Very nice and clean! Can I have it?

[JSU]

wow nice evap.....

[Unseen]

and the capline is to long.

sorry that 3,2m was at the beggining i cut it. Now it is 2,95

[kayl]

i remember that evap
you made that ages ago, did you machine it yourself or did you have someone else do it for ya

[Unseen]

a friend made it for me...

[Karnivore]

Nice Job, Evap looks very nice, your english is fine!

[Unseen]

:)

[Samael]

Once again,excelent :D
Maybe you should start producing and selling those phase change systems ;)

[Unseen]

thanks bro...i will think about it
:)

[Unseen]

Here it is a small video :)

[runmc]

Very nice "unseen"

[Redwolf]

Why do you have the condensor piped in backwords? And a sightglass on the discharge line?

[Unseen]

i think it performs the same...

[Lotec25]

Where is everone geeting the fans at? i need a smaller one for the chiller and can not find them.

Lotec25

[kayl]

i think the slide glass needs to be before the drier

[Unseen]

kayl you r right... i will change the setup in few days...

[Unseen]

from +30 to -34 took it 4:30 minutes...

[Unseen]

under candle load....

[Unseen]

-18 under the load of a 226watt peltier...

[Unseen]

my tec dont love ice.... i dont know why...

[Samael]

Stick it on the gpu man!!We are whaiting your results!

[kayl]

power the tec with 9v if ya can
also try sticking the hot side directly on the direct die block and make sure you use heat paste
sticking the thermometer on the side of the direct die block then insulate the hole lot
this will give a better idea of the temps might get.

also you need better clamping than cable ties, heat transfer will be very poor, you might damage that tec if not carful
try a g clamp or something

[100]

Lotec25:

Do a search on RSWWW, maplin or ebay for '120mm fan'.

[Lotec25]

wrong fan i am talking about the one on the condenser

Lotec25

[Unseen]

i did the changes...
is it ok now?

[Redwolf]

Much better :)

[Unseen]

some more pictures...

I put it on fx5200 just for test without insulation...

[Unseen]

this card on air from 275 can 285
on water 300 and on phase change 354

[Unseen]

one more...

[Unseen]

here i think it is at 15 loop...in 3dmark01

I want lower temps... maybe if i change the capilary? What diameter and what lenght?

1/5hp+507

[Redwolf]

What are you using now.. and what is your evap pressure?

[runmc]

If you haven't insulated the evaporator, you really need to. That would help your temps a bunch.;)

[Unseen]

i thought that with 507 i can do -50....

[Unseen]

with little tunning... :) :)

[Unseen]

i think that i have to change 507 to 410... How long do u think that it must be the capilary tube?

[100]

Unseen, what braiding is that?

[Unseen]

what "braiding " means? Sorry for my bad english....

[kayl]

braiding is the metal wire wound around you sution hose.
i dont think you can run straight r410.
need a blend of r410 and r290 and even a third gas to lower the pressure of the r410

ps what dimentions is that GPU block

[chilly1]

Looks good. By the discharge pressure I thing your capillary tube is too long the suction pressure is good at that level, I would remove 10 inches of capillary tube to get the head down.

[100]

Unseen, by 'braiding' I mean braided cloth. This is the cloth you put around your insulation (armaflex or such).

Stick 5g of R410 in, see what happens

[Unseen]

it is armaflex :)

[Unseen]

little update....

[Redwolf]

Looking better...

410A is a really nice refrigerant. Lots of btu/lb, good flow rate, nice compression ratios.
Just has the higher operating pressures and that need for oil. Which is good. Just can be messy.

[Unseen]

how long the capillary tube must be? Now i am at ~2,95meters.

[Redwolf]

With 507 or 410A?

[JSU]

You got me thinking about some r410a now.... but I dont think I can afford a $230 tank atm :(

[Unseen]

@redwolf for ~160-180watt heatload with 410?

[HawainPanda]

hey unseen, where did u get ur display?

[Redwolf]

I really dont know Unseen.
Think your going to have to experiment on cap-tube size with 410A. Shot in the dark guess.. 2.5m
Just know that your compressor is going to be running pretty hard with 410A

why do u want it? for 120euros it is yours!!! :D

i really dont remember...
