Fan enabling increased wind pressure and air volume

Abstract

A fan enabling increased wind pressure and air volume includes a driving circuit unit, a signal level unit, a signal amplifying unit, and a microcontroller unit (MCU). The driving circuit unit drives the fan to rotate; the signal level unit receives a current signal from the driving circuit unit and corrects the level of the received current signal, and sends the corrected current signal to the signal amplifying unit; the signal amplifying unit receives and amplifies the corrected current signal, and sends the amplified current signal to the MCU; and the MCU calculates based on the amplified current signal to generate a control signal to the driving circuit unit, so that the driving circuit unit follows the control signal to drive the fan to rotate and produce increased wind pressure and air volume to achieve effective heat dissipation at reduced power consumption.
