I like your idea, it looks to have a lot of promise, particularly for cooling as many boards as mine.

Is there a u-bolt that would suit the holes on the klondike?
Also would the fact that there is a through hole component make it infeasible for the klondike?

I don't quite understand what you guys mean about surface area.
Are you talking about the interior surface area that is in contact with the water?

Also instead of the nozzle, maybe you could consider something like this: http://koolance.com/dual-video-connector-adjustable-1-slot-spacing
Doesn't have to be that one, I'm sure there's standard ones you can get from a hardware store
All you would need to do is weld the cap on the end, then drill a suitable hole and tap a thread inside it.
I would trust a screw in, more than hoseclamps, even though the pressure probably isn't that high so it may not matter.
Also you could place the holes on the top rather than either end which tom_o was suggesting.

I have given up on u bolts. The boards would have to extend 10mm past the area that needs cooling and neither board layout is doing that.
My work around is to use 3mm thick flat bar, drill and tap mounting holes then tack weld the flat bar to the rectangular tube.

The take offs could be a threaded fitting or anything for that matter. I prefer the clamp fitting over threaded as aluminum is not the most durable material and I would not trust the thread in so far as me accidentally stripping it. Using a more durable material is also out due to galvanic series.

Mounting the take off at the top. The positioning is not a big deal once the air is out but I was planning mounting on top to make it easier to bleed anyhow. Drawings are just to get the idea across not technically accurate yet

The surface area was for the inside. The more surface area you have in contact with the water the more heat is exchanged, The idea of the mesh inside was to increase surface area and turbulence.

This is a sketch of my latest plan so far, I plan on having the boards line both sides and that is another good reason to dump the u bolt idea:

That looks really good. I'm going to seriously consider doing something like this for my boards.
Would there be a layer of thermal paste between the flat bar and the tube?
