More photos, unit is nearly finished :
I've added 4 pcs of 80mm fans behind the evaporator - to mount them I had must cut hole in back of fridge which later I've covered with styrofoam and new cut piece of steel plate. I couldn't mount fans before evaporator because in that way motherboard with long GPUs can't be put inside chamber (too little space) .
Testing Rig.
Noloaded I've reached nearly -49.5C air temperature inside chamber
(I haven't shooted that on photo, only -48.2C) .
From that temperature I started load testing - pumping hot air throught 30 mintes produced by hairdrier (taking over 700W from 230V) by hole for cables on back of fridge .
Big brass block (that round one) temperature after 30 minutes loadtest (remember - over 700W) .
And same but measured by small cooper block .
SS unloaded.
SS loaded with 260W after 1 hour test .
Now unit is standing for next 2-3 weeks for testing if it's leak free for sure (of course leak detector sprays haven't showed any leaks but I must be sure), after that - packing & shipping
.
Regards
Peter
