Anyone have a diagram or better pics of how this thing is supposed to work? or is that one big secret?

As far as my thermals understanding goes (pretty far as a junior ME student) the problem with radiators is the water surface area to air surface area ratio. That is to say you want more air surface area than water surface area (by a BIG factor) in order to even the difference between the heat transfer coefficient of the air which is low (~ 0.024) to the heat transfer coefficient of the water (~ 0.58)/brass/copper which is pretty high. For a simple balance of the heat transfer coefficients your air surface area would need to be ~24 times that of your water surface area to reach a balance. Obviously a little fudging is going on in the numbers for simplicities sake, but you can see where I am starting to lose it with this rad design....

In laymans terms - we have no problem heating our radiators up, it's cooling them down with such a poor heat conductor that is the problem.

The thing is that as I can see how this radiator design functions, it is trending towards a much more equal ratio of water surface area to air surface area which is not a good thing.... so theres gotta be some trick to it.
