They should probably each have a small valve at their outlets so that the flow can be adjusted and to provide some resistance so that the pressure builds up at the amp to keep the tubes full
I try to keep things simple with as few moving parts as possible. hence the hope of using conduction and convectoin currents. sort of like hot water rising and cool water replacing it.

Grey had a couple of threads on water cooling an Aleph
Searching should turn it up. He soldered copper water pipe to a flat copper bar. and installed the transistors on the bar with bolts.
I think the bar was 1/8" thick. Used convection and a large heat exchanger from a heat pump I think. Worked great, no algae problems as otheres predicted, used water as coolant. Sounds like the way you should go.

I would think that if you go that path then adding to the water some of that green stuff you put in the car radiator would be a good idea to stop corrosion and electrolysis because of dissimilar metals the water comes in contact with.Variac said:
Oil?
Yesterday on Slashdot.org, there was an interesting article about using vegetible oil to cool. In this case, they were dunking wireless networking equipement in Egypt. Oil has the advantage of not conducting. I could see one simply dunking the power transistors in the oil (not vegi, as it becomes rancid, but some form of mineral oil). I don't know the specific properties of the oils, but I suspect they would carry the heat well - see frying food. This would eliminate the problems of insulating from water. Then it would be a simple matter of using an oil cooler to take away the heat.... even massive amounts of it. Lots of these are available for little money, even free salvage- a great deal less than the amount of normal heatsinking for 1000w.
Just a thought.

wonder what my wife will say if she finds the olive oil missing or maybe the oil she uses for her sewing machine. 🙂
