Description
Technical field
The utility model relates to a kind of automotive air-conditioning system technical fields, and in particular to a kind of evaporating fan of automobile air-conditioner.
Background technique
Evaporation fan is one of the important component in automotive air-conditioning system, and what present evaporation fan generallyd use is centrifugation
Formula single shaft blower and double-shaft air blower, when using centrifugal uniaxial blower, fan blade is distributed using uniform vertical
The identical blade of (spacing of two panels adjacent blades is equal, and blade is parallel with axis)；There are one for the impeller of this blower
Fixed intrinsic frequency, each impeller back face will form vortex when blower operates, and generate certain noise；This is because each leaf
Piece spacing is uniform, is easy for that the vortex of same size can be generated behind blade, and the noise of generation will be overlapped mutually, and generates resonance
Phenomenon makes noise become very big, and when the operating of blower reaches certain revolving speed, this phenomenon can become readily apparent from, and utter long and high-pitched sounds
Sound also can be increasing, and main performance is that bass is big, and when using double-shaft air blower, rotary speed unstabilization is fixed, and discreteness is big, and
Structure is complicated, is unfavorable for production assembly, while complicated structure means that failure rate increases.
Utility model content
The technical problem to be solved by the utility model is in view of the above shortcomings of the prior art,
The evaporating fan of automobile air-conditioner that a kind of structure is simple, noise is low is provided.
To achieve the above object, the utility model provides following technical solution: a kind of evaporating fan of automobile air-conditioner, including
Pedestal, the first spiral case being set on the base and the second spiral case and the impeller being arranged in the first spiral case and the second spiral case, institute
It states and is equipped with motor between the first spiral case and the second spiral case, the motor is same with the first spiral case and the impeller in the second spiral case respectively
Axis, it is characterised in that: the impeller includes impeller baseplate and the blade for taking shape in the impeller baseplate side, the impeller bottom
The axis hole with the motor coaxle is formed at plate center, the impeller baseplate is equipped with using axis hole as center wound impeller bottom plate
The noise reduction piece of setting, the noise reduction piece extend to the neighboring of impeller baseplate from the axis hole of impeller baseplate, the blade ring around
Impeller baseplate is uniformly distributed, and the blade is wave structure.
By adopting the above technical scheme, by the way that the noise reduction piece around axis hole is arranged in impeller baseplate, since noise reduction piece surrounds
Axis hole is surround in a ring, so that originally since the intrinsic frequency of impeller causes the vortex of impeller baseplate position formation along connected drop
It makes an uproar the export of piece air port, to substantially reduce the noise that evaporation fan generates at work, and since blade is in Wave-shaped structural ring
It is uniformly distributed around impeller baseplate, since the blade of Wave-shaped structural makes the sidewall surfaces of blade or top circumferentia that phase be presented
Between the peaks and troughs arranged, noise can be constantly due to the diffusing reflection between Wave crest and wave trough when through coarse wavy blade
Acoustic wave energy is simultaneously passed to axis hole by dissipation acoustic wave energy, then is further dissipated by noise reduction piece, so that the noise that turbine is formed is in wave
Pass through multiple diffusing reflection noise reduction on wave type blade.
A kind of above-mentioned evaporating fan of automobile air-conditioner, can be further arranged to: each on first spiral case and the second spiral case
Be provided at least two buckling devices impeller being fixed in the first spiral case and the second spiral case.
By adopting the above technical scheme, by the way that at least two buckling devices are arranged on the first spiral case and the second spiral case, so that
First spiral case and the second spiral case can realize easily to fasten with pedestal and separate, and facilitate and impeller is easily put into the first spiral case and the
Inside two spiral cases, efficiently production assembly is realized.
A kind of above-mentioned evaporating fan of automobile air-conditioner, can be further arranged to: the buckling device includes the first snail of setting
Cramp on shell and the second spiral case and the convex edge that pedestal one end is set and the cramp is interlocked.
By adopting the above technical scheme, several cramps are set on the first spiral case and the second spiral case, and the cramp is setting
The reclinate prominent shape on the first spiral case and the second volute outer wall periphery, corresponding first spiral case of the pedestal and the second snail
The edge of shell is provided with the outwardly extending convex edge of a circle, and the upper end of the cramp is fixedly connected on the first spiral case and the second spiral case
Edge, and the reclinate lower end of cramp fastens the convex edge, the first spiral case enable consolidated with the second spiral case with pedestal phase
Connection.
The beneficial effects of the utility model are: being set by being equipped in impeller baseplate by center wound impeller bottom plate of axis hole
The noise reduction piece set, and blade is revised as wave structure, so that the turbine noise that evaporation fan is operated and generated substantially reduces,
In the buckling device by being arranged on the first spiral case and the second spiral case, the impeller enable easily puts into the first spiral case and second
Inside spiral case, product structure is simplified, realizes efficiently production assembly.
The utility model is described in further detail with reference to the accompanying drawings and examples.
