Abstract
The present invention provides an airflow generator, including a plate, a magnetic brake and a housing. The plate has a pivot point and a swinging end. Two magnetic poles are assembled at predefined locations on the plate nearby the pivot point. The magnetic coil is located opposite to magnetic poles of the plate, then a controller is used to control the magnetization state of the magnetic coil, thus yielding suction and repulsion with magnetic pole and driving the swinging end of the plate. The volume of the generator of the present invention is minimized, but an efficient heat-radiating effect is achieved to resolve the bottleneck of a typical radiator fan, making it applicable to the heat-radiating structure of various small-sized electronic devices.
