End and rectifier box air inlet end, rectifier box air opening end and rectifier box air inlet end are tapered, rectifier box air opening end and rectification
The respective taper flared end of case air inlet end is connect with air inlet rectifier box cabinet end, i.e. air inlet rectifier box box body diameter is respectively greater than
Enter the wind the air inlet diameter and air outlet diameter of rectifier box；
The box house for entering the wind rectifier box 2 is equipped with several groups transverse direction water conservancy diversion board group 24 and several groups longitudinal direction water conservancy diversion board group 23,
Lateral water conservancy diversion board group 24 is that several deflectors are successively horizontally set on air inlet rectifier box box house, and every piece of lateral water conservancy diversion board group
Both ends are connected on air inlet rectifier box cabinet wall by connector；Longitudinal water conservancy diversion board group 23 is that several deflectors are successively set vertically
It sets in air inlet rectifier box box house, and every piece of lateral water conservancy diversion board group both ends are connected in air inlet rectification box body by connector
On wall；
Guarantee lateral water conservancy diversion board group 24 and longitudinal water conservancy diversion board group 23 in the wind direction (length of cylinder of air inlet rectifier box simultaneously
Degree direction on) on be successively arranged alternately；
Air is inside air inlet rectifier box, and lateral water conservancy diversion board group and longitudinal water conservancy diversion board group are in the wind direction for entering the wind rectifier box
On be successively arranged alternately, when air enters inside air inlet rectifier box, due to the lateral water conservancy diversion board group that is successively arranged alternately and vertical
Air is rectified in the horizontal and vertical directions to deflector, air is entered before blower and is rectified into from turbulence state
Advection state；Simultaneously because rectifier box air opening end and rectifier box air inlet end it is tapered so that air enter enter the wind rectifier box
The impact energy that an opposite slight volume expansion reduces air is generated when internal, reduces air inlet rectifier box to a certain extent
Vibration has little influence on the advection state of air by mild crush, and can also when entering fan body after over commutation
The impact area or state of enough effectively control air and fan body, play the role of reducing fan body vibration.Above is comprehensive
The turbulence state that cooperation is pressed directly into blower interior formation with the air as caused by the effect of fan body is avoided, not only subtracts
Light air is pressed into impact failure caused by blower interior with the state of turbulent flow, it is often more important that the air of advection state avoids
Vibration, can largely reduce noise caused by the shock fan body of turbulence state in all directions.
Since air also can cause the vibration for entering the wind rectifier box to cause noise when entering inside air inlet rectifier box, entering the wind
The lateral water conservancy diversion board group that is successively arranged alternately on the wind direction of rectifier box and longitudinal water conservancy diversion board group not only can to air into
Row rectification, simultaneously because lateral deflector and longitudinal water conservancy diversion board ends are connected on air inlet rectification chamber interior wall, greatly reduce into
The noise that the vibration of wind rectifier box generates, so that the existing blower of noise ratio that fan body and air inlet rectifier box generate jointly produces
Raw noise also wants small, about reduces 20 decibels, so that the pollution of NOISE ON ENVIRONMENT greatly reduces, listen noise will not to people
Power causes to damage, or even does not influence people's lives and work.
Specific embodiment 2:
The deflector section of transverse direction water conservancy diversion board group 24 described in present embodiment and longitudinal water conservancy diversion board group 23 is in shuttle shape, and shuttle
The both ends tip of sub- shape is respectively facing the direction of air inlet and the direction of outlet air.
Deflector section is conducive to the rectification of air in shuttle shape, enables air to relatively quick be rectified into advection shape
State.
