Freon cooling an amp?

[tomahauk]

it is guy from poland ;]

i think the water cooling its practical for amps

[kubeek]

just by the way, how many watts of heat can a refridgerator transfer?

Freon cooling for amplifiers has its advantages as well as its concerns. Safety for one must be considered because if the heat sink/lines or any portion of the cooling system broke open you have the possibility for some rather nasty gas when it is exposed to flame. I can certainly see some advantages as well. In the commercial side where I have to refrigerate a room containing many amplifiers that run a large stadium system it would be a very big advantage to have the amplifiers cooled in this manner.

A basic ammonia system might prove very effective because if designed correctly it could cool a heatsink without a compressor.

Living in the world of commercial amplifiers I see how there is a trend to make them cheaper and not last. Heatsinking has a tendency to get smaller and the manufacturers try to use a small fan to cool an undersized heatsink. The result is a product that rarely makes it thru the warrenty period without repair.

I cannot help thinking you have something in mind that you would like to share.

Burnedfingers: I never knew that this type of thing was done!! Wow! Is it normal that I am salivating? Is it just air conditioning or something more substantial

Star882: You are my hero! I've seen some of your crazy projects elsewhere on the 'net. Please tell us more and I may forgive your bad taste in music.

Cheers,

Martin,

I'm not kidding here... The system I am talking about has 55,000 watts of power. The room is about 10ft X 5 ft and about 7ft tall. It is made up of freezer panels that lock together and the walls are about 5" thick.. It has its own central air conditioner that is 5 ton.
This provides the necessary cooling for the system and will keep the room at 65 degrees when the system is running full tilt and its 100 degrees outside. The equipment is inside the sign that houses the giant video display.

Did we miss the obvious here? The guy in this link (http://www.xtremesystems.org/forums/...ad.php?t=95962) is evidently insane.

I'm one of those bleeding heart liberals. But no more. I just ran out of empathy. This is so disturbing I now have to conclude that mankind deserves to die.

Hmmm freon .... the ozone layer ... hmmmmmm

What's the problem? CPUs perform better when cold. Granted, it doesn't get that much faster below about -10C or so (depending on CPU), but why not?

And of course, just read about those crazy audiophiles who would pay thousands just for a cable... Wouldn't those thousands be better spent on better equipment?

Arrrrghh!!!

Not cables again!!

Awwww Geez A CPU has a Million ot 2 discrete transistors it is a VERY complex piece of circuitry operating (usually) at mind staggering frequencies.
Cooling is often used to keep the damned things within design limits..simply out of pure necessity.. to keep it running correctly.

An amp circuit (at least the 'Good' ones) are very simple elegant circuits... operating at NO frequencies.
Heat, is normally well below the design parameters.. unless it's broken or possibly really stupidly designed :-)
