    Counterpoint: at the boundary layers, right where the air touches the fins, the main mechanism for heat exchange is conduction. Ultimately, convection is just conduction, where the medium undergoing heat conduction is a moving fluid, which massively amplifies the rate of heat exchange.

    Air is kinda shit at taking in heat through radiation, but fine at doing so via conduction and convection.
