Specific embodiment
Referring to attached drawing, a kind of low-floor rail electric car water cooling plant axial ventilator, including air duct 1, motor 2, leaf
3, terminal box 4 are taken turns,
Described axial ventilator is no water conservancy diversion chip single impellor axial fan, impeller 3 and 2 Integral horizontal type of motor peace
In the support plate in air duct 1, air duct 1 is mounted on water cooling plant cabinet body entirely through flange as a whole.
The terminal box 4 is window structure, which is mounted on air duct 1 for externally to motor wiring
Shi Jinhang operation and observation；
The motor 2 is mounted in the support plate in air duct 1, and impeller 3 and motor 2 pass through transmission shaft direct-connection transmission；
The impeller 3 includes core wheel 6, wheel body 7 and blade 8, wherein core wheel 6 and wheel body 7 cast wedging and form, impeller
Wheel body 7 is in conical structure, and blade 8 uses NACA airfoil structure.Impeller 3 is equipped with impeller dust excluding plate 5, and dust excluding plate is circular
Latten is mounted on the air intake surface of hub disk by fastening screw, prevents the concave surface of hub disk from accumulating in use
