this work?

[The Overclocker]

i have had an idea for a radiator, a large pvc tube with 10 10mm copper pipes coming out of the top in to another pvc tube. hot water goes in the bottem thought a 10mm tube, it slowly fills up and goes thought the 10 copper pipes, it will slowly cool down due to the fact it is going 10x as slow. only problem is that hot water rises

I don't think at such flowrate the hotwater makes a move.

anyone else got any ideas/ recomendations?...please

I don't think it will work any better than using the same length of copper tubing in one continuous run. It might even be worse due to the problems of maintaining consistent pressure in all the tubes. You'll probably end up with more of the water going through the tubes nearest the inlet. The ones furthest away could well be not moving at all.

As for hot water rising, just mount the thing horizontally rather than vertically. Hang a fan from the underside.

Maybe a slightly different setup would work.

Shape the ten pieces of copper tubing into large brackets like this one. [

Have the ten ['s stick out of the end of one pipe and into the end in a circular arrangement. The whole radiator will end up looking like a copper cylinder. That'll help with making sure the tubes get roughly the same amount of water flow.
