摘要： This blower apparatus includes an air blowing portion including a plurality of flat plates arranged with an axial gap defined between adjacent ones of the flat plates; a motor portion arranged to rotate the air blowing portion; and a housing arranged to house the air blowing portion and the motor portion. The housing includes an air inlet and an air outlet. At least one of the flat plates includes, in at least one of an upper surface and a lower surface thereof, a plurality of guide portions each of which is a protruding portion or recessed portion arranged to extend in a radial direction. An air flow traveling radially outward is generated between the flat plates by viscous drag of surfaces of the flat plates and a centrifugal force. Since the air flow is generated between the flat plates, the air flow does not easily leak upwardly or downwardly.

摘要： This blower apparatus includes an air blowing portion, a motor portion, and a housing. The housing includes an air inlet and an air outlet. The air blowing portion includes a plurality of flat plates arranged with an axial gap defined between adjacent ones of the flat plates; and a spacer arranged between the flat plates. A rotating portion of the motor portion includes a hub including a flat plate holding portion arranged to hold at least one of the flat plates. An air flow is generated between the flat plates by viscous drag of surfaces of the flat plates and a centrifugal force. With the spacer being arranged between the flat plates, the axial gap can be adjusted. Since at least one of the flat plates is held by the flat plate holding portion, the air blowing portion is able to stably rotate.

摘要： This blower apparatus includes an air blowing portion including a plurality of flat plates arranged with an axial gap defined between adjacent ones of the flat plates; a motor portion arranged to rotate the air blowing portion; and a housing arranged to house the air blowing portion and the motor portion. The housing includes an air inlet and an air outlet. A rotating portion includes a hub including a flat plate holding portion arranged to hold at least one of the flat plates. Once the air blowing portion starts rotating, an air flow traveling radially outward is generated between the flat plates by viscous drag of surfaces of the flat plates and a centrifugal force. Since the air flow is generated between the flat plates, the air flow does not easily leak upwardly or downwardly, and thus, an improvement in air blowing efficiency is achieved.

摘要： A centrifugal fan includes a motor, a support body, a rotating body, and a housing. The motor includes a rotor hub that rotates around a central axis extending up and down. The support body is fixed to the rotor hub and rotates together with the rotor hub. The rotating body is different from the support body in material. The rotating body is a continuous porous body. The housing accommodates the rotating body, the support body, and the motor. The housing includes an air inlet open in an axial direction and at least one air outlet open in a radial direction. A radially inner surface of the rotating body opposes a radially outer surface of the rotor hub with a gap interposed therebetween.

摘要： This blower apparatus includes an air blowing portion including a plurality of flat plates arranged with an axial gap defined between adjacent ones of the flat plates; a motor portion arranged to rotate the air blowing portion; and a housing arranged to house the air blowing portion and the motor portion. The housing includes an air inlet arranged to pass through a portion of the housing in an axial direction above the air blowing portion, and an air outlet arranged to face in a radial direction radially outside of the air blowing portion. One of the flat plates includes a projecting portion arranged to project upward and/or downward, and another one of the flat plates includes an opposing portion arranged to be circumferentially opposed to the projecting portion. Relative circumferential positions of the flat plates can be easily fixed by the opposing portion.

摘要： This blower apparatus includes an air blowing portion including a plurality of flat plates arranged with an axial gap defined between adjacent ones of the flat plates; a motor portion arranged to rotate the air blowing portion; and a housing arranged to house the air blowing portion and the motor portion. The housing includes an air inlet and an air outlet. At least one of the flat plates is defined by a non-perfect circular flat plate having an outer edge configuration in which specific configurations repeatedly appear one after another in a circumferential direction in a plan view. Once the air blowing portion starts rotating, an air flow traveling radially outward is generated between the flat plates by viscous drag of surfaces of the flat plates and a centrifugal force.

摘要： This blower apparatus includes an air blowing portion including a plurality of flat plates arranged with an axial gap defined between adjacent ones of the flat plates; a motor portion arranged to rotate the air blowing portion; a clamper portion fixed to the motor portion; and a housing arranged to house the air blowing portion and the motor portion. The housing includes an air inlet and an air outlet. The air blowing portion is held by the motor portion and the clamper portion from upper and lower sides in the axial direction. Once the air blowing portion starts rotating, an air flow traveling radially outward is generated between the flat plates by viscous drag of surfaces of the flat plates and a centrifugal force.
