Does watercooled amplifiers exist?

Gamer's computer are sometime watercooled and it's efficient.

I would like to see a class A amplifier with high power with a watercooling system.

water-cooled amp/s?

perhaps with a full or half WAVE rectifier.
And, I'd like to see the WATERFALL plot for that unit.

I own Classe DR-3 full class A

in the owners manual they tell not to fan cool because it will fool the bias current....

So I thing water cool could be great but the amp should be designe for it

As effective as water cooling is, it still generates a noise through it’s fans and pump. Something that is not favoured in an audio application.

Also, water cooling for a computer follows a somewhat universal fit which allows the parts to be mass produced at a much-reduced cost. Unless the audio industry comes up universal template (ya right!!), each water cooler would have to be custom designed with the additional costs passed along to the consumer.

I have seen cost no object amplifiers employ a water cooling solution, but for the life of me can’t remember the make and model. Perhaps another scotch will help me remember.

As for computers....my next project!

Also, there's the inevitable risk of the pipes leaking...
I don't always agree that re-caping an older amp is required, but I wouldn't disagree with anyone that wanted to have their water cooled amp/computer re-piped every 5 years!

A different computer cooling strategy, which I don't think hasn't been exploited nearly enough in audio, are heat pipes. Using them to pump the heat from the transistor to the heat sink should allow lower junction temperatures for a given size of heat sink.

Heat pipes do have their limitations and require sufficient airflow and a large dissipating surface otherwise they do not work. Also very susceptible to dust! I suspect they are not more widely used in the audio industry due to what I mentioned above with universal designs.

Water leaks do happen - more so on custom loops like pictured above than All In One solutions which is very rare. Due to advancements in technology, computers have a short shelf life in comparison to audio equipment so re-piping is not really an issue. I have a 8 year old AIO water cooler that is still as efficient as the day I purchased it…fan is a little noisy though.

Passive liquid cooling has been done before, and it avoids the problems that fans and pumps would add. The Sanyo P55 amplifier (from their under-appreciated "Plus Series" of components) had sealed tube system was liquid cooled.

I'm not sure that many amplifiers (even Class A) would ever require the kind of active thermal cooling that a high end gaming PC might. Also many audio designers (Nelson Pass for example) have found that transistors sound better when warm, so bringing a transistor down to room temperature might not be optimal for sound quality.

for sure class A amp do sound much better ounce warmed up.

My Sony TA-F55 integrated has a freon filled heatpipe for cooling,you can see it at the Vintage Knob.

I'm sure I cold setup something to attenuate pump and fan noise.

I usually inspect and clean my gears once a year, so I think I could plan something for regular pipe change, a little like a turntable strap or needle.

As for temp, I'm sure someone cold design a perfect opperation temp, so the liquide flow is control, maybe his composition too. That's not the best comparaison but heated floor are working great.

Think that’s impressive? Feast your Quantum eyes on this.

:shock: Wow!!! But I'm still waiting for my quantum amplifier with cryogenic cooling system. :P

If your objective is to keep the room from getting hot, then a water cooled amp wouldn't do that, since the heat absorbed by the water has to be released at some point.
The point of a water cooled computer is to keep the processor cool, not the room. The water absorbs heat from the processor, then circulates to a radiator, which blows the heat into the room.

The goal would be to have a class to output more power. I know it's possible but those amp are huge and pretty heavy. They have massive heatsink. It's pretty cold I have nothing against a warmer basement.

If kilowatt class A power is what you crave…..

Size of a small car weighing in a measly 1500kg, capable of producing 120kw class A into 8hms with 0.1 ohm stability. Can be custom ordered with an onboard 8 core processor sporting a 15 inch touch screen for all your digital streaming needs. Customized RGB lighting to match that new Logitech gaming keyboard to impress all your Call Of Duty friends! Will set you back $2.2 million US excluding the needed direct power connection to your local nuclear reactor. Oh…also comes with an iPod dock so you can plug in your pink Nano!!

Not water cooled but who fricken cares!!
