WebMay 16, 2024 · Passive heat sinks rely on natural convection, meaning the buoyancy of hot air alone causes the airflow generated across the heat sink system. Active heat sinks. Active heat sinks utilize forced air--commonly generated by a fan, blower, or even movement of the entire object--to increase fluid flow across the hot area. WebThis circulation cell from 30° to 60° is known as the Ferrel cell, which is a thermally indirect circulation in which cool air rises and warm air sinks. Behind the polar front in the Northern hemisphere, cold surface polar air moves from the poles toward 60°. As the air moves equatorward, it is again deflected by the Coriolis force.
