Abstract:
An objective of the present invention is to improve static pressure efficiency in an electric fan provided with a fixed vane on the downstream side of a fan. The electric fan comprises: a fan which rotates in a predetermined direction around a rotary shaft; and a plurality of fixed vanes which are arranged radially around the rotary shaft on the downstream side in the advancing direction of an airflow generated by the rotation of the fan and are curved on the opposite side to the rotation direction of the fan from the inner circumferential portion toward the outer circumferential portion, wherein the fixed vanes are configured in such a manner whereby an inlet angle formed between an inlet end through which the airflow flows and the rotary shaft, and a chord angle formed between an outlet end through which the airflow is discharged and a chord connected to the inlet end, are greater in the inner peripheral portion and the outer peripheral portion than in the radial center portion, and a discharge angle formed between a discharge end and the rotary shaft is greater than 0° and less than 50°.
