Flowing, traditional blower for vehicle air conditioning include the motor being set in the housing, driver and controller and are set to outside shell and electricity
The sensor of the impeller of machine shaft connection, controller and air-conditioning system connects, according to the temperature data obtained from sensor, control
Device adjusts the revolving speed of motor to adjust the revolving speed of impeller, to adjust the speed air flow and stream of air-conditioning system by driver
Momentum achieves the purpose of regulating temperature.But the unreasonable structural design in tradition in blower for vehicle air conditioning causes noise big
Deng, and the motor in air blower, the fever that works long hours are easy to burn out, service life is not grown.
Utility model content
The technical problem to be solved by the utility model is in view of the above shortcomings of the prior art,
A kind of good heat dissipation, low noise and blower for vehicle air conditioning with long service life are provided.
To achieve the above object, the utility model provides following technical solution: a kind of blower for vehicle air conditioning includes
Impeller shell, shell intracorporal motor and connect outside shell with machine shaft, it is characterised in that: the impeller includes cladding
The motor sleeve of motor end face and the blade for taking shape in the motor sleeve side form and electricity at the motor sleeve center
The coaxial axis hole of machine, the motor are connected by axis hole with impeller, and the blade ring is uniformly distributed around motor sleeve, the leaf
Piece is Wave-shaped structural.
By adopting the above technical scheme, blade wavy wound motor sleeve is changed to by original linear structure uniformly to divide
Cloth, so that the peaks and troughs of interphase distribution are presented in the sidewall surfaces of blade or top circumferentia, noise is passing through coarse wave
Due to the diffusing reflection dissipation acoustic wave energy between Wave crest and wave trough and acoustic wave energy constantly can be passed to axis hole when the blade of wave-like, made
It obtains the noise that turbine is formed and passes through multiple diffusing reflection noise reduction on undaform blade, achieve the purpose that noise reduction is mute, and motor set
Cylinder cladding motor end face extends the service life of air blower so that dust is not easy to enter in motor from impeller end.
A kind of above-mentioned blower for vehicle air conditioning, can be further arranged to: the shell be externally provided with to motor in shell into
The radiator of row heat dissipation.
By adopting the above technical scheme, since the fever that works long hours of the motor in air blower is easy to burn out, by shell
One radiator for carrying out high efficiency and heat radiation to motor in shell of external setting can significantly improve the use longevity of blower motor
Life.
A kind of above-mentioned blower for vehicle air conditioning, can be further arranged to: the radiator is by being arranged in shell periphery
The cooling fin in face and the round heat radiation point composition for being evenly distributed on hull outside.
By adopting the above technical scheme, the integrated molding of several cooling fins is mounted on shell by the outer wall of shell, and heat is logical
It crosses shell and passes to cooling fin, between longitudinal multiple abutting fins there is groove to increase the contact area with air, favorably
In heat dissipation, the air-flow to shed can be guided preferably to pass better heat dissipation, while shell back is provided with multiple protrusions
Heat radiation point, the setting of heat radiation point increases contact area, to improve the efficiency of heat exchange, makes the intracorporal motor of shell more
Quickly heat dissipation, the service life of the air blower of raising.
A kind of above-mentioned blower for vehicle air conditioning, can be further arranged to: the motor sleeve and impeller integrated injection molding at
Type.
The beneficial effects of the utility model are: reaching air blower by the way that the shape of blade is changed to Wave-shaped structural
Noise reduction, noise reduction effect enable the intracorporal motor of shell effective by the way that cooling fin and round heat radiation point is arranged in hull outside
Heat dissipation improves next, the service life of air blower.
The utility model is described in further detail with reference to the accompanying drawings and examples.
Detailed description of the invention
Fig. 1 is the stereoscopic schematic diagram of the utility model embodiment.
Fig. 2 is the schematic diagram of internal structure of the utility model embodiment.
Fig. 3 is the stereoscopic schematic diagram of the utility model embodiment impeller.
Fig. 4 is the stereoscopic schematic diagram of the utility model embodiment shell.
Specific embodiment
As Figure 1-Figure 4, a kind of blower for vehicle air conditioning, include shell 1, the motor 2 in shell 1 and be set to shell
The 1 outer impeller 3 connect with 2 shaft of motor, it is characterised in that: the impeller 3 include coat 2 end face of motor motor sleeve 31 and
The blade 32 of 31 side of motor sleeve is taken shape in, forms the axis hole coaxial with motor 2 at 31 center of motor sleeve
33, the motor 2 is connected by axis hole 33 with impeller 3, and the 32 wound motor sleeve 31 of blade is uniformly distributed, the blade
32 be Wave-shaped structural, and the shell is externally provided with the radiator to radiate to motor in shell, and the radiator is by setting
It sets and is formed in the cooling fin 11 of 1 outer peripheral surface of shell and the round heat radiation point 12 that is evenly distributed on outside shell 11, the motor
Sleeve 31 and 3 integrated injection molding of impeller.
When in use, the shaft for the motor 2 being set in shell 1 is screwed on the axis hole 33 on impeller 3, so that motor
2 are connected with impeller 3, when work, since blade 32 is changed to wavy wound motor sleeve 31 by original linear structure
Even distribution, so that the peaks and troughs of interphase distribution are presented in the sidewall surfaces of blade 32 or top circumferentia, noise is passing through
Can constantly due to the diffusing reflection dissipation acoustic wave energy between Wave crest and wave trough and acoustic wave energy be passed when coarse wavy blade 32
Enter axis hole 33, so that the noise that turbine is formed passes through multiple diffusing reflection noise reduction on undaform blade 32, it is mute to reach noise reduction
Purpose, since blower for vehicle air conditioning is in continuing working, the meeting heating burnout of motor 2, by dissipating several in 1 outer wall of shell
The integrated molding of backing 11 is mounted on shell 1, and heat is transmitted to shell 1 by motor 2 and passes to cooling fin 11 again, longitudinal multiple
Between abutting fins 11 there is groove to increase the contact area with air, is conducive to radiate, the air-flow to shed can be guided
Better heat dissipation is preferably passed, while 1 back of shell is provided with the round heat radiation point 12 of multiple protrusions, heat radiation point 12
Setting increases contact area, to improve the efficiency of heat exchange, makes the more quickly heat dissipation of motor 2 in shell 1, improves
Air blower service life.
