The shutter stated, shutter use multi-disc aluminium alloy vane, can be rotated in limiting slot, reach quilt after predetermined air-out direction
Limiting slot limits.
The course of work and operation principle of the utility model：
The component is assemblied in the top of large SCR rectifier cabinet, is used for the forced air cooling of radiator for thyristors.Rectifier cabinet
A large amount of hot-air is generated in cabinet 1 when silicon-controlled work, is driven by the centrifugal blower high speed rotation in PAU+FCU system component 2
Air flow at high speed generates negative pressure, the cold air outside cabinet is sucked from bottom of cabinet bulk air inlet, by controllable in rectifier cabinet
Hot-air is formed after silicon radiator heat exchange, quickly drains into hot-air by outlet air shutter after PAU+FCU system component 2
Outside cabinet, the cooling of radiator for thyristors in rectifier cabinet is completed.
Two sets of blower fan work patterns, when main centrifugal blower 7 and the work of main outlet air shutter 3, secondary centrifugal blower 8 goes out with pair
Air port shutter 9 is in off state, and system carries out forced air cooling by main centrifugal blower 7.When secondary centrifugal blower 8 and secondary air outlet
When shutter 9 works, main centrifugal blower 7 and main outlet air shutter 3 are the state that is automatically closed, system by secondary centrifugal blower 8 into
Row forced air cooling.
Two fans realize that mutual redundancy, each other pair, main outlet air shutter 3 and secondary outlet air shutter 9 use multi-disc aluminium alloy
Blade rotates in the limiting slot of the shutter frame 11 with limiting slot, and the positive pressure of air-flow will when blower fan work
Blade 5 or 7 is blown open, and blade is limited slot limit after reaching predetermined air-out direction.When wind turbine is stopped, blade of louver window 13
Since the gravity of itself is automatically closed, duct outlet is closed, vibration isolation rubber washer 12 effectively reduces outlet air blinds wind
Noise is generated when the blade rotation of window and reduces the mechanical wear that rotary shaft generates.
Above-described embodiment is used for illustrating the utility model, rather than limits the utility model, in this practicality
