Insulating for sub-ambient chilled cooling?

post #1 of 8
Thread Starter 
I have recently aquired an aquarium water chiller for free. Here are the specs of the chiller I have recieved that I know of:

VOLT: AC230/115V
FREQ: 50/60Hz
POWER: 1/3HP
AQUARIUM SIZE: 120-600L
FLOW RATE: 1200-3000L/h
CONNECTOR SPECIFICATION:16mm
REFRIGERENT: R-134a
SIZE: 467x396x526mm

My GPU and CPUare already water cooled and I intend to add this chiller to the loop. I don't know what the BTU of the unit is but it should be more than adequate to cool my components.

90-99% of the time I will be staying at or above ambient temp and will avoid going below the dew point to avoid condenstaion. However I would like the option to run the system as cold as possible from time to time. If I were to do this what would peoples recommendations on insulation be?

I have read up on insulating for DICE and LN2 and as far as I can gather these are the steps I will have to take. Whether its a small amount of condensation or alot. All it takes is one drop and that could be it! What are peoples thoughts, suggestions and advice on this?

If these are the steps I have to take then that is not a problem. The main thing I worry about is that If I am not running at below ambient temps wont all that insulation cause components to over heat? Or if its done properely will this not be an issue?

I also worry about having my case vertical because condenstaion may run down the board. I've looked through the phase change threads and I see many people running vertically though.

I take it you didn't read my OP. Thanks anyway though.

Edit: I have read the articel and I suppose he does say that he has used it in a 24/7 phase change setup. A water chiller should be no where near as drastic. Many other people seem to have used this or a similar method for 24/7 without issues.

Well I think that is the CPU sorted. Suppose I'll just go with the full LN2/DICE/Phase change insulation for the GPU as well just to be on the safe side.

Still a little worried though about fully insulating and components overheating when not running sub ambient?

I think you are set, as you said insulate round the socket and gpu like you would for ln2 and keep temps higher than dew points.
I'm not sure bout the insulation causing heat problems but your running water so there is not as much air circulating as a air cooled rig,
but I could be wrong

I will be ensuring there is plenty of airflow in the case. My only worry is having a PCB covered in liquid electrical tape or something similar. Although the VRM's and core wont be covered is there nothing else that could overheat due to the full PCB coverage when running water at normal temps?

Could you borrow or buy a thermal temp gun and see what temps come of diff parts.
People who put it on boards for testing leave it on after benching don't they?

This is what I was unsure of. If that is the case then I think I need not worry. Thanks for you input guys.
