Abstract
A fan assembly includes a plurality of rotor vanes, a motor rotating the rotor vanes with a center axis J1 as center, a plurality of stator vanes arranged in a passage of air flow generated by rotation of the rotor vanes, and a base portion including a plate-like portion and side circumferential wall. A radially inner end of the stator vane is connected to the side circumferential wall of the base portion, and a side opening is arranged in the side circumferential wall. The air flow generated by rotation of the rotor is guided along the stator vane and taken into the motor to cool of the heat generating source arranged therein.
