Technically speaking, a radiator doesn't produce energy, it _dissipates_ energy. Furthermore, your question can't be answered without providing a mass flow rate for water and air, inlet/outlet temps, radiator dimensions, etc.
Fins provide more surface area for the heat to spread, allowing more contact for passing air to absorb energy. Generally speaking, the more fins the better, up to a limit. It's a balance. More fins increase cost of manufacture and too many restrict airflow, _reducing_ efficiency.
thank you so much! well explained
What type of heat exchanger would a car radiator fall into? Plate? Shell and Tube? Something else?
Is it a good idea to install a new thermostat when not having heat does not come out but cool air does in a 2006 Buick?
Wonder about how many btu's an average car radiator would produce with 120F water?

How does the fin impact the heat transfer
