Cooling fins


Cooling fins can be found on many engines, transmissions and other components which carry considerable heat. They act as a passive cooling device, conducting heat away from the main bulk of the metal and then using the increased surface area created by the fins to cool the component with passing air. Most effective when air is moving rapidly over and through the fins, like when in motion and in the open air, cooling fins are most often seen on exposed air-cooled motorcycle engines.
