Re: Mustang aluminium radiator upgrade
A MAJOR point that has not been addressed in the thread is the fin count of the radiators in question, either aluminum or copper. As a prior operations manager for GE Heat Transfer we manufactured heat exchangers for nuke powerplants world wide, in addition to the Sea wolf submarines to name just a couple.
For the most part we used 90/10 copper nickle tubing and aluminum cooling fins. Occasionally we would get an order for copper finned heat exchangers, but for the most part they were cost prohibitive for the return on heat transfer.
Our design engineer was one of, if not THE gray beard of the industry. He actually had in his office the original heat transfer book. We referred to it as the holy grail. It was done in pencil including all the graphs during the great depression. As a matter of fact, the new heat transfer text books use the exact same graphs.
Anyway, back to the point. Fin count cannot be left out of the design criteria. Are there 12,14,16 18,20 fins per inch? Fin count equals cooling surface. Within reason, the greater the fin count and contact point (collar) between the tube and fin, the greater the opportunity for heat transfer. Other factors such as airflow and what you are putting through the cooling tubes, Glycol, holy water (super clean water) assist or impede heat transfer.
All other factors remaining the same, I would rather have a copper radiator with 16 fins per inch rather than an aluminum radiator with 12 fins per inch.
Fin count is probably more critical in this application than the material the cooling medium is flowing through.
