摘要： An axial flow fan includes an impeller rotatable about a central axis with a plurality of rotor vanes, a motor that drives the impeller, a base portion that supports the motor, a housing that includes an intake vent, an exhaust vent, and an inner peripheral surface surrounding the impeller and the motor, and a plurality of stator vanes that respectively connects the base portion and the housing, wherein the inner peripheral surface includes a first inner peripheral surface arranged to increase a distance from the central axis toward the intake vent or the exhaust vent in an axial direction, and a recess provided between the first inner peripheral surface and a stator vane included in the plurality of stator vanes and facing the first inner peripheral surface. Thus, airflow is allowed to smoothly pass through the housing, resulting in a decrease in noise generated in the fan.

摘要： A frame for a serially connected axial flow fan unit includes a first housing and a second housing coupled together. The first housing includes a first axial locking mechanism and a first unlocking mechanism, and the second housing includes a second axial locking mechanism and a second unlocking mechanism. The first and the second axial locking mechanism are locked against each other through their movement along their axis. The first and the second unlocking mechanism unlock the first and the second housing with a twisting force equal to or greater than a predetermined value when the first and the second housing are twisted relative to each other. When the first and the second end portion are brought into contact, the first and the second axial locking mechanism are locked against each other and the first and the second unlocking mechanism engage with each other.

摘要： A serial axial fan unit includes first and second motors with their base portions, i.e., first and second base portions axially facing each other. A motor gap is arranged axially between the first and second base portions. An axial length of the motor gap is preferably in a range from approximately 0.3 mm to approximately 2.0 mm. This configuration reduces transmissions of vibration of each of the first and second motors to the other, thereby reducing vibration interference between the first and second motors.

摘要： A housing assembly for a fan unit includes an upper housing having a lower engaging portion adjacent to its lower end surface and a lower housing having an upper engaging portion adjacent to its upper end surface. When one of the upper and lower housings rotates relative to the other about a center axis of the housings in a first direction with the opposing end surfaces of the housings in axial contact, the lower and upper engaging portions engage with each other. While the lower and upper engaging portions are in engagement, one of the lower and upper engaging portions presses the other in both axial directions to cause elastic axial deformation of the other; and one of the lower and upper engaging portions presses the other toward both the first direction and a second direction opposite thereto to cause elastic circumferential deformation of the other.

摘要： A counter-rotating axial fan includes two impellers each having a plurality of blades and two motors for rotating the impellers, respectively. The impellers are rotated by the respective motors in directions opposite to each other. The impellers and the motors are surrounded by a housing which defines an air path through which a current of air generated by rotation of the impellers flows. The housing includes an expanding portion, at which an area of a cross section of the air path substantially perpendicular to the center axis is larger than that in an axially middle portion of the housing, located between the first impeller and the second impeller.

摘要： In a motor, axially upper and lower end surfaces of the stator core are substantially covered by a first insulator and a second insulator, both of which are made of resin. A boss is arranged circumferentially between two neighboring teeth. Three bosses are arranged at three out of four positions defined between any two neighboring teeth. A conductor pin is inserted into each boss along an axial direction. The boss includes a hole extending axially upward from the axially lower end thereof, in which a conductor pin is fitted. An axially lower position of the conductor pin axially downwardly protrudes from the boss. The conductor pin is inserted into each of the notched portions arranged to the circuit board, and is soldered with the circuit board such that the conductor pin and the circuit board are electrically connected.
