Abstract
The invention discloses a vehicle-mounted air conditioner air blower, and belongs to the technical field of automobile manufacturing. The vehicle-mounted air conditioner air blower comprises impellers which are driven to rotate by a motor. The two ends of a motor shaft extend outwards. The two impellers are symmetrically fixed to the two ends of the motor shaft. Each impeller comprises blades arranged in the axial direction. The distances between the blades are not equal. One end of each blade is rotated by 5 degrees in the axial direction and the anticlockwise direction. The impellers are symmetrically fixed to the two ends of the motor with the two ends of the motor shaft extending outwards, and therefore the air flowing property and the stability of the draught fan are high in the running process, and under the condition that the air volume is the same, the noise of the air blower is low, the air outlet pressure is high, comfort of an air conditioner of a whole vehicle is greatly improved, heat exchange of an air conditioner evaporator is accelerated, and air conditioner performance is improved.
Description
Technical field
The present invention relates to field of automobile, especially a kind of blower of on-board air conditioner.
Background technique
What vehicle-mounted air-conditioning blower generally adopted at present is monolateral shaft wheel hub motor, and the impeller being sleeved on single side axis is also monolateral, and the blade on its impeller is parallel with axle, and is to be uniformly distributed; Because the each Leaf positional distribution of impeller is even, blade easily produces identical little eddy current, the noise that these eddy current produce is stack mutually, produce resonance phenomenon, make noise become very large, noise pollution meeting damages human body, in addition the monolateral shaft wheel hub motor that vehicle-mounted air-conditioning blower uses makes motor shaft monolateral stressed, high to motor installation requirement, easily produce vibration, stationarity is poor.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of vehicle-mounted air-conditioning blower, easily produces vibration when work that this vehicle-mounted air-conditioning blower can solve existing vehicle-mounted air-conditioning blower, the poor and large problem of noise of stationarity.
In order to address the above problem, the technical solution adopted in the present invention is: this vehicle-mounted air-conditioning blower, include the impeller rotating by driven by motor being arranged in housing, and the axle of described motor stretches out from two ends respectively, described impeller is two groups, and symmetry is fixed on the two ends of described axle.
In the technological scheme of above-mentioned vehicle-mounted air-conditioning blower, technological scheme can also be more specifically: described impeller has the blade arranging vertically, described blade each other distance is unequal, and the angle that described blade one end rotates in the counterclockwise direction at axle direction is a.
Further: described angle a is 5 degree.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, the present invention is under identical air quantity, and blower noise is low, improves greatly the comfort property of whole-vehicle air-conditioner.
2, air-out blast of the present invention is large, accelerates A/C evaporator heat exchange, improves heat pump performance.
3, the two ends of the motor that is fixed on two-way shaft of impeller symmetry of the present invention, therefore this blower when operation the distinguished and admirable property of blower fan and stationarity good.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is A-A place sectional view in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Vehicle-mounted air-conditioning blower shown in Fig. 1, Fig. 2, includes the impeller 1 that passes through motor 2 driven rotary being arranged in housing 3, and the axle 2-1 of motor 2 stretches out from two ends respectively, and impeller 1 is two groups, and symmetry is fixed on the two ends of the axle 2-1 of motor 2; Impeller 1 has the blade 1-1 arranging vertically, and blade 1-1 each other distance is unequal, and blade 1-1 one end rotates 5 degree in the counterclockwise direction at axle direction.
When work, motor 2 energising rotations, impeller 1 is rotated, gas between impeller 1 is also with impeller High Rotation Speed, due to gas rotating centrifugal action, can be thrown out of through the gap between the blade 1-1 of impeller 1, the gas of throwing out forms pressurized gas through the extruding of housing 3, goes out from exhaust outlet; The gas that is so simultaneously positioned at 1, impeller is thrown out of, extraneous gas under atmospheric effect along impeller 1 axial inlet intake impeller 1.Due to the blade 1-1 of impeller 1, distance is unequal each other, and blade 1-1 counterclockwise rotates 5 degree at axle direction, has eliminated the noise that stack produces, and impeller 1 is symmetricly set in the two ends of motor 2, and when operation, blower stationarity is good.
Claims (3)
1. a vehicle-mounted air-conditioning blower, include the impeller (1) that passes through motor (2) driven rotary being arranged in housing (3), it is characterized in that: the axle (2-1) of described motor (2) stretches out from two ends respectively, described impeller (1) is two groups, and symmetry is fixed on the two ends of described axle (2-1).
2. vehicle-mounted air-conditioning blower according to claim 1, it is characterized in that: described impeller (1) has the blade (1-1) arranging vertically, described blade (1-1) each other distance is unequal, and the angle that described blade (1-1) one end rotates in the counterclockwise direction at axle direction is a.
