Description
Technical field
A kind of electric machine assembly is the utility model is related to, is specifically used for the motor for eliminating high-voltage motor cooling fan noise
Cooling fan low noise fan housing.
Background technology
Being both known about in the industry for use motor, when in use, its top is typically covered with protective cover to high-voltage motor, in order to
Stand-by motor radiates, and protective cover is generally fitted with cooling fan below one end.In order to protect cooling fan, prior art is to adopt
Surrounding sets the mode of protection network on the outside of cooling fan.However, cooling fan is operationally, it will usually produces larger make an uproar
Sound.Protection network only plays a protective role to motor cooling fan, without performance muffler.Therefore, the motor using this fan housing is cold
But noise caused by fan be all be directly delivered in environment, it is larger to harmful effect caused by environment, caused by make an uproar
Sound pollution is more serious.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of motor cooling fan low noise fan housing, uses the fan housing
It can avoid producing noise pollution.
To solve the above problems, provide following technical scheme：
Motor cooling fan low noise fan housing of the present utility model, including housing, there is air intake in the front end side wall of housing
Mouthful.It is characterized in also including exterior cover pipeline, the nozzle of exterior cover pipeline is fixed on the surrounding of air inlet, edge in the side wall at exterior cover pipeline nozzle end
Its circumference is evenly equipped with opening.There is ventilating duct in the exterior cover pipeline, ventilating duct both ends are opening-like, and one end of ventilating duct is fixed on
The surrounding of air inlet, there is spacing between the other end of ventilating duct and the cylinder bottom of exterior cover pipeline, ventilating duct external diameter is less than the internal diameter of exterior cover pipeline,
So as to which between the abutting end of the cylinder bottom of exterior cover pipeline and ventilating duct, ventilating duct is cylindrical forms air channel between exterior cover pipeline inner circle.It is described outer
Silencing cotton is all covered with housing exterior walls on the inwall of cover cylinder, on the inwall of ventilating duct between ventilating duct and exterior cover pipeline.
Wherein, the housing is the spiral case in vertical.
There is screen pack in the opening.
It is in arranged concentric between the exterior cover pipeline, ventilating duct and air inlet.
Above scheme is taken, there is advantages below：
Due to having exterior cover pipeline, exterior cover pipeline on the outer wall of the housing of motor cooling fan low noise fan housing of the present utility model
Side wall is evenly equipped with opening, there is ventilating duct on the housing exterior walls in exterior cover pipeline, on the inwall of exterior cover pipeline, on the inwall of ventilating duct and leads
Silencing cotton is all covered with housing exterior walls between air duct and exterior cover pipeline.In use, the fan housing is installed to high-voltage motor protective cover one
The lower section of side, cooling fan is installed in the air inlet of fan housing.This fan housing is utilizing exterior cover pipeline and ventilating duct protection cooling
While fan, also using on the housing exterior walls on the inwall of exterior cover pipeline, on the inwall of ventilating duct between ventilating duct and exterior cover pipeline
Silencing cotton noise caused by cooling fan is isolated, eliminated, the noise being delivered in environment greatly reduces, and eliminates pair
The harmful effect of NOISE ON ENVIRONMENT caused by cooling fan, avoids noise pollution.
Brief description of the drawings
Fig. 1 is the structural representation of motor cooling fan low noise fan housing of the present utility model；
Fig. 2 Fig. 1 left view schematic diagram；
Fig. 3 is the schematic diagram of the exterior cover pipeline of the motor cooling fan low noise fan housing of invention in the deployed state.
Embodiment
It is described in further detail below in conjunction with accompanying drawing the utility model.
As shown in Fig. 1 ~ 3, motor cooling fan of the present utility model includes housing 6 and exterior cover pipeline 4, shell with low noise fan housing
Air inlet 7 is provided with the front end side wall of body 6.The nozzle of the exterior cover pipeline 4 is fixed on the surrounding of air inlet 7, the nozzle of exterior cover pipeline 4
In the side wall at end opening 8 is evenly equipped with along its circumference；There is ventilating duct 3 in the exterior cover pipeline 4, the both ends of ventilating duct 3 are in the shape of opening 8,
One end of ventilating duct 3 is fixed on the surrounding of air inlet 7, has spacing, wind-guiding between the other end of ventilating duct 3 and the cylinder bottom of exterior cover pipeline 4
Cylinder 3 external diameters be less than exterior cover pipeline 4 internal diameter, so as between the abutting end of the cylinder bottom of exterior cover pipeline 4 and ventilating duct 3, ventilating duct 3 it is cylindrical with
Air channel 1 is formed between the inner circle of exterior cover pipeline 4；On the inwall of the exterior cover pipeline 4, on the inwall of ventilating duct 3 and ventilating duct 3 and exterior cover pipeline 4
Between the outer wall of housing 6 on be all covered with silencing cotton 2.
In order to improve refluence performance, the housing 6 is the spiral case in vertical.
In order to prevent foreign matter from entering, there is screen pack 5 in the opening 8.
It is in arranged concentric between the exterior cover pipeline 4, ventilating duct 3 and air inlet 7.
In use, the fan housing is installed to the lower section of high-voltage motor protective cover side, cooling fan is installed to entering for fan housing
In air port 7.High-voltage motor at work, starts cooling fan, and due to the effect of blower fan, outside cold wind is successively by opening 5, outer
Between cover cylinder 4 and ventilating duct 3, after ventilating duct 3, air inlet 7 and housing 6, enter in high-voltage motor protective cover, high-voltage motor is entered
Row cooling, complete to reduce the purpose of high-voltage motor temperature.
