Abstract
The utility model relates to a motor noise-reducing fan housing, which comprises an air inlet, a shutter, an air-intake cavity sound-absorbing material, an air outlet, an air-out cavity sound-absorbing material and an air-outlet silencer. According to wind-path characteristics of a motor, a fan housing is provided with the air inlet and the air outlet, and a cold air area and a hot air area are separated by the use of a separator plate; and the sound-absorbing material is additionally arranged at the maximum noise radiation place so as to prevent noise. In order to reduce wind resistance increasing and motor temperature rise increasing caused by the additionally-arranged sound-absorbing material, the separator plate and a wind-guiding plate are disposed in a streamline manner. Thus, wind resistance is minimized, and wind can flow more smoothly in the fan housing.
Description
Technical field
The utility model belongs to technical field of motors, relates to a kind of fan housing, relates in particular to have the fan housing of the motor of low noise requirement.
Background technology
Continuous adjustment along with rapid economy development and economic structure, market is to big capacity, the demand of high-quality motor constantly increases, power of motor is constantly increased, for the more heat of loosing at limited heat-delivery surface, must add forced ventilation, incident will be the increase of ventilation noise, the IP23 high-voltage motor that particularly degree of protection is lower, the acoustical absorptivity of motor internal and fan housing is very poor, the inner noise that produces almost has no to pass to the outside with hindering, cause noise very high, obviously traditional fan housing can't satisfy the strict demand of user to the noise proposition of motor, this just presses for a kind of fan housing, can either consume motor internal because the energy of the noise that rotor and fan rotation produce can satisfy again and take away the heat that motor internal produces.
The utility model content
The purpose of this utility model is to overcome the above problems, and provides a kind of motor with noise reduction sound fan housing, can reduce noise, can fully take away the motor internal energy again, satisfies the requirement of ventilation and heat.
For achieving the above object, the utility model solves by the following technical programs:
This kind motor comprises the fan housing housing with noise reduction sound fan housing, is provided with air intake cavity and air-out cavity in the described fan housing housing, and described air intake cavity is provided with the air inlet that leads to motor internal, and described air-out cavity is provided with the air outlet that communicates with motor internal; Also be provided with the blind window that communicates with the air intake cavity on the sidewall of described fan housing housing; In the air intake cavity, be provided with air intake cavity sound-absorbing material, be provided with air-out cavity sound-absorbing material in the air-out cavity; Described air outlet is connected with the air outlet silencing means.
The shape of above-mentioned air intake cavity sound-absorbing material and air-out cavity sound-absorbing material flows to into streamlined according to the wind direction of air intake cavity and air-out cavity.
Further, above-mentioned air intake cavity sound-absorbing material and air-out cavity sound-absorbing material are noise reduction wave sponges.
Be provided with dividing plate and wind deflector in the described outlet and inlet cavity, place one deck noise reduction wave sponge at the dividing plate and the wind deflector of outlet and inlet cavity.Described noise reduction wave sponge sticks on dividing plate and the wind deflector, and uses the web plate secure fixation.
The utlity model has following beneficial effect:
The utility model consumes motor internal by sound-absorbing material because the energy of the noise that rotor and fan rotation produce makes noise can't be radiated the motor outside, greatly reduces noise.Simultaneously, the air channel includes air intake cavity and air-out cavity, makes the air channel very smooth smooth, has reduced windage, has guaranteed that the motor internal heat discharges effectively, thereby has reduced electric machine temperature rise.Simultaneously, the utility model also tool easy to assemble, safeguard good looking appearance, advantage such as cost is low, and is reliable.
Description of drawings
Fig. 1 is the structure chart of motor of the present utility model with noise reduction sound fan housing;
Fig. 2 is an air outlet silencing means structure chart of the present utility model.
Wherein: 1 is air inlet; 2 is blind window; 3 is air intake cavity sound-absorbing material; 4 is air outlet; 5 are air-out cavity sound-absorbing material; 6 is the air outlet silencing means; 6.1 be mounting panel; 6.2 be angle steel; 6.3 be noise reduction wave sponge.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1, a kind of motor of the utility model comprises the fan housing housing with noise reduction sound fan housing, is provided with air intake cavity and air-out cavity in the described fan housing housing, described air intake cavity is provided with the air inlet 1 that leads to motor internal, and the air-out cavity is provided with the air outlet 4 that communicates with motor internal; Also be provided with the blind window 2 that communicates with the air intake cavity on the sidewall of fan housing housing; In the air intake cavity, be provided with air intake cavity sound-absorbing material 3, be provided with air-out cavity sound-absorbing material 5 in the air-out cavity; Air outlet 4 is connected with air outlet silencing means 6.The shape of described air intake cavity sound-absorbing material 3 and air-out cavity sound-absorbing material 5 flows to into streamlined according to the wind direction of air intake cavity and air-out cavity, it is happier that wind is flowed in fan housing, reduced windage, thereby reduced electric machine temperature rise.The rectangle semi open model cavity that air port silencing means 6 is made up of mounting panel 6.1, angle steel 6.2 and noise reduction wave sponge 6.3, as shown in Figure 2, mounting panel 6.1 is connected with air outlet 4.
External refrigeration wind enters the air intake cavity by blind window 2, enters motor internal by air inlet 1 then, the cooling motor parts that respectively generate heat, and the heat of taking away enters the air-out cavity by air outlet 4, discharges via air outlet silencing means 6 at last.
In preferred embodiment of the present utility model, described air intake cavity sound-absorbing material 3 and air-out cavity sound-absorbing material 5 are noise reduction wave sponges.Because rotor and fan rotate the energy of the noise that produces, play the effect that reduces noise in order to consume motor internal.Wind path characteristics according to motor, dividing plate and wind deflector at the outlet and inlet cavity are placed one deck noise reduction wave sponge, and at fan housing exhaust outlet installation air outlet silencing means, for preventing that sound-absorbing material from entering motor with gas, sound-absorbing material must be sticked on dividing plate and the wind deflector, and use the web plate secure fixation.The air channel not only will separate cold wind district and hot blast district with dividing plate, also will consider to reduce windage, and wind is the requirement of smoothness more fluidly in fan housing.
In sum, a kind of motor of the utility model is easy for installation, easy to operate with noise reduction sound fan housing, after the installation, can satisfy the requirement that reduces noise, can fully take away the motor internal energy again, reduces electric machine temperature rise.
