Abstract

A serial fan assembly includes a first fan, a second fan and an air-guiding structure. The first fan and the second fan are arranged in serial and the air-guiding structure is disposed therebetween for guiding airflow flowing from the first fan to flow into the second fan along a direction which is parallel an axial direction. As the result, the airflow volume and air pressure are increased and the noise is decreased during fans' operation. Also, power loss is compensated comparing to conventional fans, and the present invention improves flexibly of assembling and fabrication.
