hi'ya
anyone know if you'd get much of a drop in temp at the cpu by water cooling a vapochill XE.......??
any one done it,,,,,i'm looking for ideas on a water cooled condencer design.....
cheers for any input.....
:D

I know a few people have watercooled the condenser and got slightly better temps (7c or so, but it might have been chilled water).

hi'ya gkiing
thanks for getting back and for your input......
also wondered if it would make it more stable at big oc and big volts ie. 3ghz and 2.1v,,,,,cos it seem happy enough then, booffff the temp shoots up to like 30-40c, like the cooling collapses..........thought a water cooled condenser might stabilise the cooling more........

yea
im using a watercooled condensor
coz i cant find any small size condensor 2 fit in a casing
so i made a coiled condensor.... 1/4" copper tubing
and then made a reservoir which fits the coiled condensor...
hope the pics helps you..

yeah,,thanks for that BuLKhY,
did it change the preformance much.....??

that would be like dual cascade.....

That is a cascade, just with a very ineffeciant method of transferring the heat. If you bought a HX it would work much better and you wouldn't need to deal with all of that water.
A cascade is simply 1 phase change systems evaporator cooling down anothers condenser.

yes but i read disings of chilly one and i found it very difficoult for me, instead i find easy to built a DD and a waterchiller...

Go look at a HX, once you see it its usage should become clear.

i was thinking of using something like this...
watercooled conderser (http://www.acalacr.co.uk/Water_Cooled_Condensers.htm)
or this
another one (http://www.turbotecproducts.com/coax.htm)

wau those watercooled condensors looks neat....
actually when ur benching n trying to get lower temps
u can actually add some ice into ur reservoir to get a lil lower ...

The HX is the thing basicly centered in the picture with the orange caps.

oh my god it seems quite difficult to do :slobber:
any guide???but a waterchiller and a phase change will be a lot more bad than a cascade? i will be happy to hit -100 whith no load :D

ok i think to have descovered how it works, well i have 10 months and 13 days to build one ^^

Actually i think that the interstage hx is the tube in shell coaxial condenser (the grey coils on the far left). The hx with the red caps is more likely a suction line hx, not the cascade hx as its a bit small..

the suction line hx can be used as an interstage hx, but it isn't as efficient as coxial

That is a watercooled condeser for the 1st stage.

Isint the condenser on the far left on the bottom shelf in that picture? I can see the bottom few rows of an air cooled condenser.
That is a tube in shell refrigerant heat exchanger btw, designed to transfer heat between the cool vapour of the suction line and the liquid refrigerant line.

well yea, i meant that both can be used for an interstage hx, but the one on the left is a water-cooled hx. it is more efficient than a suction line hx (more surface area). suction line hx is just to increase efficiency of the system by cooling the suction line

"The coil is actually a water cooled condenser. I'm going to use it for an interstage condenser. There is a tube running inside a tube. It will use the first stage refrigerant (r-404a) to cool the low stage refrigerant.(R-13)
"
The interstange hx is the large grey coil which is actualyl a watercooled coaxial condenser.
If you look down the page you will see another image in which the tube in shell hx (the one with the red ends) brazed on so the liquid line on the filter drier of the filter drier goes into the hx where it contacts the suction line.
on the second page runmc shows more images which show the air cooled condenser.
that's a really good thread btw..

coaxial condenser makes a good hx interstage.. good luck with future cascade. now i just need to save up some money to start mine

I want to build a cascade after I get this damn single stage working properly. The first waterchiller I built I didnt have any problems with. I would like to become accustomed with the safety protocols and cutoff devices before I build a cascade though. I would say that a cascade is at least 8 months away.. and Ive got a lot of other stuff tow ork on. I've got most of the theory of the cascade down but would like to spend a lot more time on the design rather than the assembly to make the best combination of all the parts and make it efficient, and hopefully not take up its own room.
The hx on the left techinicaly is a water cooled hx but he uses it as a interstage. You can see his whole cascade over at teampuss.com

if I want to make a selfmade watercooled condensor (coiled 1/4" copper pipe), how long should it be ?
tictac

2Meter :)

around 10-15' will work well. Putting it in a PVC pipe makes it easy to cool.
thats the only bad thing about cascades that stuff expensive
gkiing
10-19-2004, 12:16 PM
and they can blow up if safety cutoffs arent used, for example the high staige fails and the low side psi goes up.. and up till the compressor hopefully lets the pressure out.

it depends...i don't how much costs the condenser that work whith the two gases but for the are things, not more than 100€ if you have already manometer vacuum ecc ecc....

Do you mean 15' as in 450 cm ?
gkiing
10-19-2004, 04:17 PM
i meant 10-15 feet as in 3-4.5m. For a watercooled condenser if you go below a certain length (the pipe is in a coil of course) you will loose efficiency, but also if you make it too long it will just be overkill and restrict the system.
