Abstract
The utility model discloses a condensing fan of an automobile air conditioner. The condensing fan comprises a fan frame body, a motor and fan blades, wherein the motor is connected with the fan frame body in a fastening manner, a rotating shaft of the motor and a shaft core of the fan blades are coaxially connected and matched, and a brushless direct current motor is adopted as the motor. Compared with the prior art, the condensing fan provided by the utility model has the beneficial effects that 1, the brushless direct current motor is adopted for driving, the brushless direct current motor has no electric brushes, thus no mechanical contact or abrasion exists between a stator and a rotor, and the motor does not need to be maintained, and has long serve life; 2, the motor is high in efficiency, compact in the structure, and low in work noise; and 3, the assembly accuracy is improved, and the condensing fan can be conveniently transported and stored, and great economic benefits are created.
Description
Technical field
The utility model relates to a kind of condensation fan, belongs to the Fan Equipment technical field, refers in particular to a kind of used for automobile air conditioning condensation fan.
Background technique
Existing car air conditioner condensation fan adopts permanent magnet DC motor driving impeller of blower to come Cooling Air-conditioning System.Permanent magnet DC motor adds that VDC just starts working, and whole system is simple in structure, and compactness has obtained using widely in car air conditioner.But permanent magnet DC motor all has carbon brush and commutator.Brush and commutator have rubbing contact, so such permanent magnet DC motor needs often to safeguard, even need change brush over time; Brush is easy to cause the motor short trouble can staying on the commutator by some conductive powders of generation after the wearing and tearing simultaneously.Thereby the life-span of this type car air conditioner condensation fan is shorter.
The model utility content
The purpose of the utility model is to overcome shortcoming of the prior art with not enough, and a kind of simple in structure, long service life and non-maintaining used for automobile air conditioning condensation fan are provided.
In order to realize above-mentioned purpose, the utility model is realized according to following technological scheme:
A kind of used for automobile air conditioning condensation fan includes blower fan support body, motor and fan blade, and said motor and blower fan support body are fastenedly connected, and machine shaft is connected cooperation with the blade shaft core is coaxial, and motor adopts brshless DC motor.
Further, said fan blade includes some blades and a wheel hub, and blade and wheel hub are one-body molded.
Further, the blade edge edge of said fan blade is 2.0 ± 1mm with the gap of blower fan support body.
Further, the blade rotating angle of said fan blade all adopts fillet structure.
Further, be provided with stiffening rib in the wheel hub of said fan blade.
The utility model compared with prior art, its beneficial effect is:
1, adopt brshless DC motor to drive, brshless DC motor does not have brush, thereby does not have Mechanical Contact between stator and the rotor, do not have wearing and tearing, thereby motor does not need to safeguard that electrical machinery life is long;
2, electric efficiency is high, compact structure, and operating noise is low;
3, improve assembly precision, helped transportation and storage, had very high economic benefits.
In order to understand the utility model more clearly, below accompanying drawings is set forth the embodiment of the utility model.
Description of drawings
Fig. 1 is the Facad structure schematic representation of the utility model.
Fig. 2 is the side structure schematic representation of the utility model.
Embodiment
As 1, shown in 2; The said used for automobile air conditioning condensation fan of the utility model includes blower fan support body 1, motor 2 and fan blade 3, and said motor 2 is fastenedly connected with blower fan support body 1; 3 cores of motor 2 rotating shafts and fan blade are coaxial to be connected cooperation, and motor 2 adopts brshless DC motor.
Above-mentioned fan blade 3 includes some blades 31 and a wheel hub 32, and blade 31 is one-body molded with wheel hub 32, and reaching blade 31 edges of fan blade and the gap of blower fan support body 1 is 2.0 ± 1mm, and blade 31 corners all adopt fillet structure.Further, be provided with stiffening rib in the wheel hub 32 of said fan blade.
The utility model is not limited to above-mentioned mode of execution; If spirit and scope that the various changes or the modification of the utility model do not broken away from the utility model; If these are changed and modification belongs within the claim and equivalent technologies scope of the utility model, then the utility model also is intended to comprise these changes and modification.
