Abstract

An impeller includes a metal base plate, a shaft and a plurality of plastic blades. The metal base plate includes a shaft-coupling portion, a peripheral portion, and first and second surfaces. The first surface faces away from the second surface in a first direction, and the second surface faces away from the first surface in a second direction. The metal base plate is flat between the shaft-coupling portion and the peripheral portion. The first surface has a permanent magnet. The shaft has a fixing end coupled with the shaft-coupling portion, as well as a free end extending axially in the first direction. Each plastic blade has a coupling portion coupled with the peripheral portion, as well as an air-driving portion axially extending in the second direction. The impeller may be rotatably coupled with a driving module. The driving module is installed in a fan frame to form an advection fan.
