Abstract:
A fan device (10) according to an embodiment is equipped with: a housing (11) equipped with an intake chamber (INR) for taking in external air through an intake port, a storage chamber (LR) which connects to the intake chamber via an opening, and an exhaust port for discharging air inside the storage chamber to the outside; a motor (12) equipped with a coil (125) and provided inside the storage chamber of the housing; a fan (13) which draws air inside the intake chamber through the opening into the storage chamber, blows air from the storage chamber to the exhaust port, and is provided on the rotating shaft of the motor; a sealing member (14) for sealing the intake chamber; and a channel (BW) for air which is drawn into a gap (GP2) between the housing and a first surface (13b) of the fan as a result of the air-blowing operation of the fan, returns to the opening (17c) through a channel hole (11h) provided in the housing and connected to the intake chamber (LR), and is drawn into a second surface (13a) of the fan which opposes the first surface thereof.
