KumKum's new unit | WoRkLoG :-)

Hi

Some days ago member KumKum from this forum ask me about new unit ... more powerful subsitute for his Vapochill LS, becasue he wasn't really satisfied with temperatures ....so ... :

Specs :

Compressor: HIGHLY CHW 33TC4-U - it's 18000 BTU/ 1.5 HP rotary
evap: steeper by piotres
XV: captube 0.8 mm
condenser: 3 row, cooled with 4 x 120 mm 12v fans
Refrigerant : R507+R410a blend
Case : Chipboard base plate 32 x 40 cm, painted black
Others : SLHX - 15mm with 1/4' inside, around 50 cm long

I want to reach sth like -48-50*C@225W load :-) .

It's worklog ...I've start making this unit yesterday, and till now I've worked on it not more that sum of 2 hours ;-).

So I have only make baseplate (sorry for very poor picture, I promise that next ones will be much better ) :



I can't promise, but maybe tomorrow I'll be having more time and I'll do some more work .

Regards
Peter

hi

no pb Piotres

take your time and fact us as usual of the very good work

I will follow while dribbling a little lol on this topic



I like already the baseplate

and I imagine the remainder above
yes I have much imagination


to follow... ^^

Today I prepared condensor :





and braze suction line :

Peter

Nice work

3 rows now ^^ ok its better

Yes 3 .

Today I insulate suction line :



Tomorrow no work - I go with mine girlfriend on journey .

Regards
Peter

Kiss your girlfriend for me ^^

Nice day to you

New work done yesterday and today :





I've decided to add small SLHX ..15 mm pipe with 1/4' inside .







Next part of work I plan to make this weekend .

Regards
Peter

As ever, Nice work

Try to fill with pure R410a

yes pure R410a whith the SLHX
it will be cool... no ?? lol

Today I've done :



Evacuation .





Electric .







And later unit made devil's number hehe . I've tryied pure R410a and I've found that blend with R507 is much better ..with pure R410a hiside with 225W load goes up to 19 bara, -54*C evap - but that was with no insulated SLHX (23*C ambient) and later I've swap it for R507&410a blend (around 90%/10%) ..hiside max 15 bara and -57*C@225W .



Final charge, no load .



225W loaded = -57*C evaporator



Tomorrow I plan to test unit on E6600ES and later pack it .

Peter

load temp' are impressive
well, with such a monstrous CP, it would not have been normal if temp' were crappy

Hi

Sorry Guys, today I must go to bed now, but I've packed unit today and it's ready to go .

BTW. Today it has made -70.3*C unloaded sitting on CPU, and lower than -59*C stressed on E6600ES oced .

Tomorrow new pictures .

Peter

nice temp'

if you authorize me Piotres

By mp he give me 3.9Ghz with 1.6v of Vcore to be more precise -59.8c idle and -59.4*c same settings in load

well even if it's not a "high load", still impressive temp' : almost the same between idle and full load

yes also in fact ^^
I was also say that as it is appropriate

or I badly read or understood ^^

but if you also compare for example with this other powerfull dod 1 stage by Piotres the results in about the same in load and it is what I expected and asked some
http://www.cooling-masters.com/forum/sujet...iotres-931.html

I meant even if 3.9GHz@1.6V is not such a big heat load, it's amazing the way temp' are almost the same between idle and full load

yes I agree well on this point on as I have say it in my post preceding
Piotres will inform us on this point and my owns tests in live also and especially relating to me ^^
but the powerfull CP, the optimized mixture of 2 gases as well as the SLHX, undoubtedly explains also that

And it is clear that I will go much higher even without MOD but that nevertheless makes it possible to compare because it always keeps the same parameters

let us not forget that we are there with a DOD 1 stages "only" and not auto-cascade ^^ and this result is perfect for me

Hi

Promised pictures:





100% finished .



Evap temp just before turn PC on ...



E6600ES @ 3.9Ghz/1.6V idle. Damn mine unmoded Asus P5N-E SLI don't want to run much over over 430 FSB . That's why so low clock , and vcore without vmod is poor too . Sorry guys for that.



Same in stress during SuperPi ...as You can see 0.5*C diffence, I think it show power of that "little" compressor .







Ready to go ...

Best Regards
Peter

beautiful tiling, beautiful screen, beautiful case ( google sponsor )

I await it now

I will undoubtedly do one limps out of plexiglass 8 mm

so i big pb when i open the box

see that guys



a valve of filling broke and remains untraceable in more in limps (???)

thus well on the empty circuit and the unusable dod


I have join piotres but it did not answer me yet because I knows it in this moment very occupied by its final school examinations


thus my questions

1- did somebody knows in Paris area where I reside a good craftsman or even you who read me able 1 to resolder a perfectly hermetic valve ?

2- To fill is the circuit with proportioning with origin of Piotres 90% of R507c and 10% of R410a ?

thank you to help me guys

un conseille bouche le trou comme tu peut en attendant
