Default Experimental Water Chillers

For those who are excited about extreme cooling and definitely experimental cooling, you might enjoy discussion.

I want to start a debate and discussion on Water Chilling ideas.

For the most part we all know there are 4 main cooling systems we can all use.
- Air Cooling
- Water Cooling
- TEC
- Phase Change

Now by my own definition "Water Chilling" applies to water, TEC, and phase change.

Water must be cooling by a Radiator or rather heat from the water to be removed via a radiator.

TEC can be used on the processor itself or be used to cool the water itself.

My personal favorite, Phase change units can be used in a few different ways to chill water.

Sometime in the near future I want to post a worklog on experimenting with a 5000 BTU window A/C unit to do water chilling. However a good old debate on theory and ideas would be more helpful at this point in time. Surfing the web for hours has just boerd me with other peoples attempts.

SO, A/C unit being used to cool your computer. I can think of a dozen different ways to make it work but what do YOU THINK

As soon as the coolant being used drops below ambient room temperature condensation will start to form on the tubing, waterblocks rad etc...

I'm not exactly a refrigeration expert but I think this is one way: Get a large bucket or cooler, fill it with coolant, toss in the coils from the A/C unit along with the rad from your watercooling loop.

Just check our XS for some ideas.

Water-chilling really isn't that efficient I'd just go for phase-change if you plan on going that far. Liquid cooling is usually enough for your daily needs.

Oh I agree with you all. I just want to slap some ideas out there on what could work.

I don't really want to do it, I just want to experiment with the idea. Hell, Phase change or using anytime of A/C system is more or less like plugging in another fridge or window A/C. Not exactly cheap.

So shoot, got any niffty ideas stuck up in them heads???

Get a beer fridge and toss in the rad.

Refrigerators don't work for cooling heat sources, or water that is cooling a heat source.

You can safely buy yourself a few degrees with a water-chiller by setting it's thermostat at ambient temperature, whereas even a good water cooling setup will still have the water a couple degrees above ambient. If you case has good airflow across all the parts close to the chilled water, you can set the chiller a couple degrees below ambient without any fear of condensation.

Yea, Fridges are not a good idea. Mind you I can see possible methods of turning a fridge into a workable cooling system.

One thing I would like to try AGAIN, is pelter water chilling. I have seen a number of versions, home made and purchased ones that have been modified.
I would like to make one the works along with a standard water cooled system. Cools the coolant after the rads to drop the temp as close or JUST below room temp.

I just had a thought.

The Peltier water blocks that swiftech sells... Does anyone know if the peltier can be reversed?

I have never gotten the pleasure of closely observing on before. That would be a PERFECT solution for a water chiller. Considering you can simply mount any higher end heatsink to the bottom of the block.

*note
I am assuming that the peltier is 100W give or take. A 250W would just cause any high end heatsink to GLOW with heat.

Reversed??? What do you mean by "reversed"? Do you mean having a waterblock-TEC-heatsink combo attached to a loop after the rad so that coolant becomes chilled?
