Abstract

The utility model discloses a noise reducing device for an air conditioner compressor, which is applied to air-conditioning equipment for a railway traffic vehicle. The noise reducing device comprises a rubber plate, a foam plate and an aluminum foil, wherein the rubber plate is arranged outside a casing of the compressor and is used for insulating sound; the foam plate is arranged outside the rubber plate and is used for absorbing the sound; and the aluminum foil is arranged outside the foam plate. A hoop is further additionally arranged outside the casing of the compressor so as to reduce vibration noise. In the noise reducing device, the noise is reduced by adopting a mode of combining sound insulation with absorption. The noise reducing device has the advantages of simple structure and favorable noise reducing effect.

Description

The air condition compressor denoising device
Technical field
The utility model relates to a kind of air condition compressor denoising device, is applicable to the compressor that adopts the air-breathing cooling motor of refrigeration agent, is applied on the air-conditioning equipment of rail traffic vehicles.
Background technique
Along with the comprehensive speed-raising of China's train and the raising of people's living standard, people are more and more higher for the requirement of train air-conditioning comfort level, and except the temperature and quality of air, its noise is also more and more paid close attention to by everybody.In order to satisfy the user to the requirement of train air-conditioning than high degree of comfort, air-conditioning unit noise reduction also becomes the important topic of everybody research gradually.
Existing rail traffic vehicles air-conditioning equipment is under the normal reasonably situation of its structural design, and its noise mainly comes to three critical pieces: evaporation fan, condensation fan and compressor.Evaporation fan adopts centrifugal usually, and it is logical to be installed in air-conditioning unit indoor side, and its rotating speed is general, and air quantity is also general, so noise is general.Condensation fan adopts axial flow usually, is installed in air-conditioning unit outdoor, and its rotating speed is general or higher, but air quantity is bigger, so noise is higher.Compressor rotary speed is very high, usually up to 2900rpm, so its noise is very high, is of noise maximum in three main noise sources.Can reduce its noise by reduction rotating speed, optimization air distribution for evaporation fan and condensation fan people; According to domestic existing development technique level, can also require blower fan supplier to carry out specialized designs, to realize noise reduction according to the concrete structure of unit.For compressor, divide from its pattern to mainly contain vertically and horizontal, divide from its working principle to mainly contain eddy type, piston type and screw type, divide from its motor radiating mode to mainly contain the heat radiation of housing appearance and cool off and the air-breathing cooling of refrigeration agent.Existing compressor noise-reduction measure mainly contains compressor is installed on the framework by vibration damper, is used to reduce vibration between compressor and framework reducing the vibration of compressor noise, but its motor noise that produces that runs up is not had noise reduction measure preferably.
The model utility content
The technical problems to be solved in the utility model provides a kind of air condition compressor denoising device of simple in structure, excellent noise reduction effect.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of compressor noise-reduction device, its key technology is: it comprises the rubber plate that is used for sound insulation of the outside of being located at compressor, the aluminium foil of being located at the foam plate that is used for sound-absorbing of rubber plate outside and being located at the foam plate outside.
Further improve, also be fixed with anchor ear, be provided with the yielding rubber plate between the housing of described anchor ear and compressor in the outside of compressor.
Adopt the beneficial effect that technique scheme produced to be: the rubber plate that is used for sound insulation that 1, is provided with in the utility model is mainly used in high frequency noise; Foam plate can further absorb the noise after intercepting, especially low frequency noise; Aluminium foil is laid in the outside can make its appearance become attractive in appearance on the one hand, also has waterproof and certain deadening on the other hand.The mode that combines by sound insulation and sound-absorbing is controlled targetedly to the noise of compressor different frequency range like this, thereby reduces its running noise significantly.
2, by install additional anchor ear compressor housing is tightened fixing, cushioning vibration isolation rubber plate between anchor ear and compressor housing simultaneously, thus reduce its vibrating noise.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1;
Wherein, 1, aluminium foil; 2, foam plate; 3, rubber plate; 4, anchor ear; 5, compressor; 6, yielding rubber plate.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Be that example describes the utility model now with Emersonian vertical scroll compressor.Referring to accompanying drawing 1 and accompanying drawing 2, the utility model comprises the rubber plate that is used for sound insulation 3 of the outside that is pasted on compressor 5, the aluminium foil 1 that is pasted on the foam plate that is used for sound-absorbing 2 of rubber plate 3 outsides and is pasted on foam plate 2 outsides.The density of rubber plate 3 is higher, is mainly used in the obstruct high frequency noise, and foam plate 2 is mainly used in the absorption low frequency noise, and the outside aluminium foil of being pasted 1 can not only play and beautify outward appearance and waterproof action, also has certain deadening.The mode that the utility model combines by sound insulation and sound-absorbing is to reduce the compressor operation noise.
In order further to reduce the compressor vibrating noise, installing anchor ear 4 additional in the outside of compressor 5 tightens fixing, between the housing of anchor ear 4 and compressor 5, be lined with yielding rubber plate 6 and aluminium foil 1, between clip 4 and compressor 5 housings, can not add foam plate 2 that is used for sound-absorbing and the rubber plate 3 that is used for sound insulation, like this can effective more fastening compressor 5.The hardness and the thickness of yielding rubber plate 6 are moderate, to play the chucking function, guarantee its level of freedom again, thereby play the effect of vibration reduction and cushioning.Especially vertical compressor, its center of gravity is higher, and it is more obvious to install the anchor ear damping effect additional on the housing top of compressor.
Because of denoising structure described herein needs compressor housing is wrapped, in order to guarantee its motor radiating cooling, so the utility model only is applicable to the compressor that adopts the air-breathing cooling motor of refrigeration agent.
