The Spearco IC catalogue has some decent graphical sizing data for their
IC's. Don't know if they have it on line or not. If you know how to size
heat exchangers graphically, their stuff is pretty usable. Frontal area,
cooling air flow, core thickness, efficiency, pressure drop, etc. can all
be determined to a reasonable degree of accuracy for a given set of
operating conditions.
