Hi guys!

I just completed a very time consuming project. Somebody from the German forums needed a chiller for a LianLi V2000 case which he could just "drop in" as he already had the case. After some considerations, I used a Danfoss SC12G, R134a, an Cold_Ice Deluxe condenser, a Danfoss TXV with 01 orifice and a plate heat exchanger.

The chiller should have a large reservoir so it would not turn on very often an operation should be fully automatic after pressing the computers power button (chilling down, then starting to boot).



The unit is mounted on a 5mm aluminium plate to prevent bending of the very thin base of the LianLi case. I did put about 20 M3-threads in there to screw the base plate later into the case. The condensor is mounted a little on top of the base plate to use the full opening in the case front and also to be able to use the front-USBs.

To collect liquid refrigerant, 2 connected 22mm copper tubings were used. All in all it was really tight in there...



After insulation and doing the first wiring...



... and the back...



For the reservoir 3 5,25" slots were available. The res. was glued together from PVC plates, connections were threaded in and also glued in for safety.



With 6mm Armaflex insulation and in place...



The controller came from B+B Thermotech in Germany and can do a lot more than a standard Dixell: 4 Outputs, 3 thresholds, PID, and, and, and...



To get rid of the about 1.5 kilowatts of heat during cooldown via the little poor deluxe condensor, I had to provide some venting: The used diagonal fan from EBM Papst should be some of the most powerful fans on the market. 270 m3/h, 6000 rpm, 21W power. The most ingenious thing of this fan is, in contrary to the Deltas, it is made to provide max. dressure differential, not max. free blowing air volume. I reached a wind speed of about 5m/s through the condensor, with a Skythe UltraKaze 3000 I just reached about 2.4 m/s...

The only really downside of this fan is its price: 94 Euros (about 137 US$)...

The sound is something annoying after a time, so the controller switches the fan from 12V to 7V if water temperature drops below 13C. This level of sound is ok.

With this fan I reached at max. 50C liqu. temp.



Electrics...



... and mounted!



Themost annyoing of this project was that everytime I tried to fit something i, some few millimeters were missing...



And its backside.

To do: Switching the wooden plate in the back (for mounting PS) and the white PVC plate (for mounting the controller) to aluminium.

I am satisfied with the power: It cooles down almost 3 liters of water from 24C to 10C in about 3 minutes.

And now I have some workspace back for another project...

Philipp
