Patent abstract
A method of cooling blower components may include rotating a fan assembly (160) responsive to operation of a motor (120). The rotation of the fan assembly may create an underpressure region in an inlet portion (154) and an overpressure region at a main channel (340) of the fan assembly (160). The method may further include drawing air into the inlet portion (154) through a control unit housing portion (132) of a housing (110) of the blower (100) to cool a control unit (130) of the blower (100), drawing air into the inlet portion (154) through a battery compartment (142) to cool a battery (140) of the blower (100), and pushing air from the main channel (340) through a motor housing (320) to cool the motor (120).
