Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in figures 1 to 6, a kind of DC fan system, including, movable vane wheel 5, inducer and motor 4.Movable vane wheel includes
Chassis 9, the blade 8 that centrifugation is laid on chassis respectively, the upper disk 6 being located on blade is covered, impeller air inlet is offered on upper disk
13, formed with impeller air outlet 14 between upper disk and the edge on chassis, blade is set to biplate circular arc, and blade has 9.Inducer
Outboard cover sets front shroud 2, and wind wheel air inlet 1 is opened up on front shroud, and the accommodating cavity for accommodating movable vane wheel is formed between inducer and front shroud, moves
Impeller 5 is arranged in described accommodating cavity, and the bottom of inducer sets wind wheel air outlet 10.Impeller air inlet 13 is arranged on disk
Centre position, wind wheel air inlet are arranged on front shroud centre position, and movable vane wheel 5, inducer, motor 4 are coaxially disposed, set on movable vane wheel
Axle sleeve 7 is put to be used for connecting motor.The output shaft of motor is through inducer bottom and connects described movable vane wheel 5.Impeller air inlet
Upper setting flange 14, flange 14 are stretched into wind wheel air inlet 1, reduce air leakage.
Wind wheel air outlet 10 is arranged to triangle, and arc is laid in inducer bottom outer ring, the height of wind wheel air outlet
Gradually changed by drift angle to base from high to Low, the back side of the bottom of inducer is centripetal to be provided with guiding gutter 11, guiding gutter it is defeated
Enter end linking wind wheel air outlet.The trough rim of guiding gutter 11 is set to biplate circular arc, and wind wheel air outlet 10 is provided with 8, described
Guiding gutter is correspondingly provided with 8.The inner ring diameter size of the diameter matching wind wheel air outlet of movable vane wheel 5.
Motor 4 is through inducer and connects movable vane wheel 5, then motor driven movable vane wheel high speed rotary motion, in movable vane wheel
Air is thrown away at a high speed along the circular arc direction of blade 8 under the influence of centrifugal force, flows out air at a high speed from impeller air outlet 14, so
The wind wheel air outlet 10 from inducer bottom outer ring flows out afterwards, takes advantage of a situation and imported into guiding gutter 11, and an air part for discharge arrives
Motor surface is cooled down up to the surface of direct current generator, also some enters motor internal, and inside is cooled down
Cooling, so as to extend electrical machinery life.Air in accommodating cavity forms vacuum turntable after being discharged, less than pressure initiation outside blower fan
Pressure differential, then under air pressure effect, the air of inducer front shroud 2 is inhaled into, by wind wheel air inlet, impeller air inlet,
