Hello

One more unit, this time it is not standart . It is "cold plate" chiller in orginal vapochill LS case.

Don't ask me for what is that - I have order for it so I make it . Planned load is approx 0W. I'll be used to cool other metal plates (scientific experiments).

Goal was -30C somewhere on plate- I get approx -43C with final tune on copper plate:). It has eliwell controller so temperature can be risen.

SPECS:
Compressor: Aspera NEK2134GK
Evap: 4mm thick copper plate 20x20cm cooled by 3/8' roll pipe - evap mounted between copper and alu 3mm thick (sandwich)
XV: captube 0.8 mm
Condensor: stock vapochill LS + 120mm/38 12V Panaflo fan + 120mm/38 12V Nidec fan
Refrigerant : R507
Case : stock Vapochill LS case
Others: Eliwell IC915 controller,Panaflo 120x38mm 12V fan on back of case

Image

Image

"tool" for making roll evap

Image

Image

Not perfect but it is best I can make .

Image

Image

Image

Milled.

Image

Image

And the sandwich is ready.

Image

Now we take 100% stock vapochill LS.

Image

Image

After less than hour ...

Image

Owner will mount NTC probe to controller (that is why it reads "E1" - no probe plugged).

Image

With Kindest Regards

Really nice, quiet unusual in the phase-change sphere, how did you manage the floodback ? Running in deep vaccum ?

Edit : you gave me a nice idea for my cold room, maybe I'll swith my air evap for that kind of plate

Any problems with floodback - it have quite big suction accumulator made from empty 40 grams drier . And suction pressure is approx 0.0 bar.
