Cold plate in vapochill LS case

[piotres]

Hello

One more unit, this time it is not standart :D. 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 :). 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

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

Very cool, you can use these things to mix icecream flavors while keeping them cold ;)
Lot's of fun!
And an interesting way to do it.
The other option is to flatten a lot of straight tubes and parallel them up.

Nice project Peter! :up:

I found my kind of evap' for my cold room !!

Nice idea Piotres !

[Crabby]

I bet it would be great at keeping your drinks cold, atleast 4 of them at a time. I like your evap., did you braze it to the plates?

[piotres]

No, pipe is not brazed to copper plate, it is only pressed to cooper by bolted aluminium plate :).
