First watercooled SS by piotres

Hello

It's mine first liquidcooled SS . Very simple unit, medium size rotary compressor and plate HX (20 plates) . R507 freon .

Member of this forum ordered it because he got already in house chiller made from AC unit producing around +5C liquid . So can get a nice boost .

Specs :
Compressor:TECO KETC176ELBC-A
Evap: Steeper 40mm tall/42 mm diam., enclosure for all newest CPUs, 80 cm braided DN10 suction line (with stainless steel mesh)
XV: captube 0.9 mm
Condensor: plate HX (20 plates)
Refrigerant : R507
Case : Wooden baseplate, painted on red color
Safety : Johnson Controls hermetic cut-off (can be useful when coolant flow will be suddenly cut off)
Others: Two handles to comfortable move of unit, "quick" nipples for 12/16mm hoses

I decided to mount quite nice working and looking "quick" nipples :).

I always test it in +16C water (direct flow from instalation in house), owner told that he plan to use it with +5C water so that should give small temperature boost also :).

http://www.piotres.boo.pl/sswatercooled/17.jpg

First try.

Final unloaded (using +16*C coolant).

http://www.piotres.boo.pl/sswatercooled/21.jpg

That was on 260W dummyload using +16*C coolant. Finally I've added bit more R507 for "safety" and temperature is like -44*C@260W after 1 hour test.

I like your attention to detail Peter that build looks very nice.

Very nice build!!! thinking of doing something similar:D
What about the compressor, he doesnt have ventilation....

Compressors works fine. Discharge pressure even loaded is close to 10 bara so it doesn't heat up too much .

Yes you are right, and the customer has the chilled 5c water! DAMN
Maybe a new freon is needed, or some mixed freons, close to the BP of r13b1.

Very cool build, Pieter! :up: With this sort of subambient condensing, you may as well have used R-410A without any problems! :)

Very nice, Boost indeed!

Wow that's HAWT

what copper pipes can you connect to this plate hx?

i have also two pieces of the same 20´s phx but they have only 4 of 12,5mm inlets to connect 12mm copper pipes.

are you using 15 or 16mm pipes for the water cycle?

Very nice work :up:

Nice... being a noob... what is the water actually cooling here ???

Water condense refrigerant (R507) in this system .

Yes, I have 15mm OD cooper pipes in liquid loop . Strange Plate HXes You have bought :-O . On the other hand that's good because to cascade we don't need such big "reduction" of size.

I know that, I've tried R410a but haven't notticed lower temps compared too R507 . That gas which is now in unit is even blend of some 410a with more 507.

The water loop replaces the condenser and fan like on a typical single stage.

Ah i see ... sweet ... so what happens if for instance the water pump fails while unit is running ???

how quiet will you box the compressor?

Chain reaction!! :(

Refrigerant stops condensing and the phase change process comes to a screeching halt.
Evaporator gets hot and in turn your $1500 Extreme cpu gets hot and sizzles. :cussing:

the high pressure cut off switch will stop the unit. maybe you can also connect the power socket of the computer to the cut off switch.

i see so that's what it's for :)

Usually this will save your 1500$ cpu (mine has :P):

Besides has anyone got C2 series cpu burned anyways (due the internal heatprotection?)

I was being humorous with eva 2000 :yepp: My guess is that he knows what happens when a cpu get too hot. :D

Yep, nothing happens :)

Nice and clean build there

Nice looking "simple" unit! Always great craftsmanship from you piotres:up:

Well, Patrick - that's VERY GOOD idea :yepp: :up: !

On how much presure is that cut-off switch set piotres?

22bar(g)

22 bara was factory set (out of box) , I set it to 25 bara like I always set.

What should i say. ......Really good work. Stay tuned

would this work in a water chiller setup as well?

i was thinking,

use a plate HX on the hot side like you have it as a condenser but use watercooling radiators to remove the heat from the water.

on the cold side use another plate HX as the evaporator to chill the water for the PC's waterloop.

it would likely be quite a small setup and could be added into an existing waterloop with the addition of another waterpump and insulation of the pc components.

your thoughts?

Interesting idea ;) Sb can try it ;) . Maybe one day anybody will order such crazy cooler from me ? :rolleyes:

Lol. that's all mine ;)

I ordered mostly because somebody in another thread told, that this is a stupid idea.

The first test was with C430 - I just added some settings (and some good voltage). I did not look for the highest OC, just wanted to see how it reacts.
The EVAP temp dropped only 0,7c under load :up:
http://www.upload.ee/image/185124/vbn.JPG

Because I had to work with my bench rig yesterday and the Celeron was (is) still there, I changed the FSB to 450 and voltage to 1,5v and was working with my stuff with the Celeron overclocked to 4 Ghz :rofl:
During the 4-5 hours, the liquid temp rised from 2c to 8c. The load temp came town to -49,5 (from -50,5). I have too strong mixture in a cooling system - I'll try to add some pure water to improve it.
Hopeing to have cold weature soon - I will add a rad and kick it outside then :rolleyes:

I will post some real results later.

wow impressive results don niger :)

Hi

this is my first post in this forum and I like to start something not so complicated and this thread made me like to start something, I can find anything what piotres has but one the HX plate.

anybody can give me suggestion where and how much cost for HX plate ?
if I cant any plate HX locally I planned to use tube in tube can any body give me formula how to calculate length ?

thankyou

In our country Brazed Plate Heat Exchanger Very Expensive around $200 for small size, $400 for medium size & $600 for large size.

OMG 200USD
Ok I think I will take tube in tube way may be if some one can give me detail how to made HX I will more than happy to ask my workshop to build it.

what about cut an condenser from an old AC and put in a box and let the cold water flow in it, can it work, again any formula to calculate ?

You can do it (tube in tube) but I do not think of possibility the calculate now! Because there are other influential factors such as the capacity of the compressor and the efficiency of liquid cooling....

and this my old experience and the result is good with the X-Changer Triple 360mm Radiator ..

Very nice unit :up:

So is using water better the using air?

Thanks

Yes, it is better I think. I couldn't boot higher than 3,8Ghz with C430 before (refilled Mach II). With this one, 4,08 is not a problem - possibly even more but cheap AData 2GB memory sticks can not go higher.
~13K is waiting for somebody to catch up

*I'm just setting up the system - too bad I do not have enough time for that.

This is old project (almost a year ago) I'm sorry I do not have a lot of photos, but my next project will be using the HX plate and I will try to put a lot of details here. Of course, that this method for those who want to get more quiet compared to the traditional way "Condenser + fan"

Thank you

Hmm, cann't say - so far so good. It did well with low load but failed after installing E8600. Trying to figure out what's wrong.

Nice work but i suggest testing it also with 5C water. You might find out that it wont hold the same load.

Since you used r507, with 16C water you get around 9-10bar condensation. With 5C water you get 6-7bar condensation, at such a low discharge pressure you might get too much restriction from the captube. ;)

Edit: i see now its an older thread and the owner already got the unit.

Well, from what You sent me :

"E8600 5,25Ghz @ 1,65v
Idle
Outlet max (coolant) +2,6C, your probe max -51,9C, new probe max -50,4C CPU max -48C
Orthos 5 min run
Outlet max +1,5C, your probe max -46,8C, new probe max -37,9C CPU max +7C"

DonNiger mount another Kprobe, near bottom of evap from what I know ..

Just saw this as @quintus linked it in another thread. Really nice stuff!

really interesting idea about how to make chiller more quiet (if the dissipation surface of the watercooling radiator is big enough)

p.s. sorry for necroposting.
Piotres, really awesome unit. It inspired me much :D
