Surface radiators

[GasSavers_Pete]

Shrek,
Surface cooling has been used in aircraft and was very popular for the record breakers in the Schneider Cup series during the 1930's.
For cars though the varying demands of changing speeds and stop - start traffic may make it unworkable.
The costs of making the panels to the necessary tolerances may also have a negative impact on the demand.
Speaking of impacts one reason the conventional "core and end tank" arrangement has become standard is the ease of repair and installation by the factory.

Cheers , Peter.
