Preferably, first, second, third fan is made of the circle wheel of periphery and internal blade, described
Circle wheel can lace.
Preferably, the blower housing is internally provided with multiple connecting poles, is used for fixing shell.
Preferably, the tapered ring-type of the block piece.Block piece ensure that air-flow is blocked part and draws into fashionable generation
The case where leading, large area gas current friction installation position edge avoided to generate vibration as possible.
Preferably, the transmission system further includes belt, described first and second, third fan circle wheel pass sequentially through
Belt is connected, and the motor is mounted in the shaft of the first fan, during transmission, because efficiency is declining always,
Therefore, the fan of different-diameter is driven by the belt pulley of different order.
Preferably, the motor connects transmission system, and the motor is filled material and surrounds.Due to the limit of motor itself
System, motor itself also will produce vibration, and therefore, selection surrounds motor using filler material, effectively absorbs the vibration of motor,
Reduce the noise of motor itself.
Preferably, the support column of the enclosure is equipped with spring.The upper spring of support column, also plays and subtracts
The effect of shake.
Preferably, the damping layer thickness is 2-7mm, and the TPU film package layer thickness is five points of foamed layers
One of.
Compared with traditional axial fan, the application changes the form of conventional fan, reduces wind to a certain extent
The vibration of machine optimizes wind turbine configured in one piece using multiple settings for crossing wind face, reduces the side effect that mechanical oscillation are brought, and
And it is provided with shock absorption buffering mechanism in the enclosure interior of wind turbine, reduce the possibility for generating overall resonance.
