Abstract
A fan system includes a first airflow generator providing a main airflow, a duct having a first feeding port to guide the main airflow, and a first fan. The first fan includes a base, a rotor connected to the base by a shaft, and a plurality of blades connected to the rotor. Each blade includes a passive part corresponding to the first feeding port and an active part. The main airflow drives the passive part rotating about the shaft to synchronously rotate the active part, dissipating heat from a heat source, increasing flow rate of airflow and decreasing pressure. The amount and location of the fans can be flexibly configured.
