Crazy idea about watercooling...

Here is a funny idea that would look kinda cool, dont know if anyone has done it yet. Why doesnt someone hook up a couple of canisters of compressed air facing their radiator and somehow rig up a switch to be able to spray the can upside down into the radiator so that the cool spray would spray though it to cool it off real quick? Its kinda like a purge valve that sprays on the intercooler. I dont think you could have it run all the time but for a quick cool down it would work. Stupid idea? Cool idea? Thoughts? I know its kinda crazy but I think it would be kinda cool... :p
 
its kinda cool well how bout an air compressor?? I just bought one with blow gun(3HP 5 gallon twin tank) it blows out pretty cold air... what else could I use it for???... I used it yesterday to put air on my tires...
 
Interesting Idea.

But you're gonna get a lot of water residue on the rad. When you spray the can upside down all the compression forces the water out of the air and onto whatever you are spraying. This extreme cold also goes all over the can...can't imagine it being very good. And its gonna go through the rad onto whatever is behind it too. On top of all that once the air leaves the can in its slightly liquid state it doesn't stay cold for a very long time.

I think anyways....this is all just speculation. :D
 
another problem is you would be cooling the radiator not the water it would take awhile for the temps to drop and by the time you got a noticable drop your "air" would run out

the air compressor trick doesn't work well either i have a 5hp and even that won't push the volume of air. how yours is kicking out cool air i i don't know. When you compress a gas (air) it becomes warmer then factor in its getting the air from the room it will be warmer then room temp??

i have had my rad installed externally before and when i wanted "cooler" temps i would dunk it in a bucket of ice water. not very practical and wont' work for internal setups but fun to try.
 
I've seen it done, a kid from Poland cannibalized an automotive nitrous system (just for show) and hooked up a T-line to his waterblock input. He also added one of those exhaust-flamers that ignite a pressurized gasoline tap in an exhaust tip, so that when he used flammable compressed gas like butane it would make this huge flame come out of the top of his case. It's fun for about two minutes.

Using an air compressor would be more practical, but you'd still have a huge electric bill for the compressor running in your garage with an air line run into your office. Genuine pneumatic cooling, though, that could actually be fun.
 
I made a post about doing this almost a year ago. It does work, but it's incredibly inefficient. It would probably be good for getting through a round of 3DMark or something, but thats about it. You would be much better off submersing your radiator in a container of ice water. That would be cheaper, last longer and would probably work better too.

That only happens when you are compressing while spraying, it you have a tank of compressed air that has been sitting and then spray it, it will be cooler from the pressure drop in the tank, example as in bottles of C02 for paintball or pc cleaning compressed air that will ice over as you spray - the pressure drops cooling the air (which is how a refrigerator works- compresses refrigerant(hot) releases to a lower pressure area (cold)). Now regular air is not nearly as efficient as some liquids or other gasses (why we use freon, etc.. in cooling) if your really interested you can look up Boyles law which explains it mathematically
 
i understand that letting the air sit in the tank then spraying will "cool" the air like refrigerent but in practice DeViLdUdE said he had a twin 5 gallon tank so that would be 10 gallons. If you compress the air to 150 psi (the most a typical compressor goes) let it sit for however long for it to cool you will only get "cool" air untill the pressure drops to about 40 psi with a ten gallons tank your looking at 5 minutes max then the compressor needs to kick back on to compress more air then the heat of the compressor and all starts in again, so you would need to wait again for it to cool this would never work in real life.
 
Co2's the Gas you need.... Derv people use for cooling intercoolers all the time...

Problem with co2 is that it will kill you :eek: :rolleyes:
 
i dont think he means constantly spraying it on the radiator. just a short burst. its the same idea as holding up a bag of ice or something frozen up to the fan blowing air through the radiator. the whole idea is to get colder air over the radiator. this one is a good idea just for a quick drop in temps

Yes thats exactly what I meant, I didnt want it to run constantly only some burst...
 
Co2 is the gas then if its short bursts... It gets Very cold when sprayed...

but if you breath it in you could collapse a lung...

I have a Bottle in the Car waiting to be filled with co2 for a mate... 10lb bottle filled for £15
 
yea Co2 is dirt cheap and since would only be a short burst you could use it

but i would suggest rigging up some kinda vetilation with fans going out a window or something while using it.
 
yeah and a 10lb bottles good for summit like 2 - 3 mins of Constant Release.

If you were to rig the bottle to nozzles and have a Purge setup from a car on the Radiator and just rig up a button so the longer you push the button the longer it blasts...

If i remeber correct my mates Valve/soliniod will only take 3 secs b4 it burns out and stays open :/

But a 1 - 2 sec burst would cool ALOT
