Air-conditioning sound pad
Technical field
The utility model relates to automotive trim field, is specifically related to a kind of air-conditioning sound pad.
Background technology
Air-conditioning is a kind of common household appliances, and noise is the key factor affecting air conditioning comfortableness index, and be also one of important indicator evaluating air-conditioning quality, it not only causes the pollution of surrounding environment, and affects the live and work of people.Along with improving constantly of expanding economy and living standard, people are more and more higher to air-conditioning noise index request, and air-conditioning products is except the performance that must have and safety index, and low noise is also one of important indicator improving product competitiveness in the market.The noise of air-conditioner outdoor unit is mainly derived from Compressors and Fans.Spread out of medium-high frequency electromagnetic noise during the machine operation of compressor body, spread out of medium and low frequency mechanical noise when compressor drum rotates, mutually superpose in the propagation process of sound wave of each frequency band, to external radiation.At present, usually the air-conditioner outdoor unit noise reduction technology adopted, the Sound-proof material that adopts carries out noise reduction and sound insulation more in the market, on Vehicles Collected from Market, existing Sound-proof material is at parcel compressor, partial isolation its noise-reduction effect cotton does not still reach requirement, lower tone, cacophonize, is difficult to the control overflow meeting air-conditioning products noise.
Utility model content
For above problems of the prior art, the utility model provides the good air-conditioning sound pad of a kind of soundproof effect.
The utility model is achieved through the following technical solutions:
Air-conditioning sound pad, described air-conditioning sound pad is made up of trilaminate material compound, and it is the cotton layer of two component at the middle and upper levels, and middle level is rubber slab, and lower floor is anion PET acupuncture carpet veneer; The two component cotton layer thickness in described upper strata is 1-3mm, and described middle level rubber slab thickness is 1-3mm, and described lower floor anion PET Nomex layer thickness is 1-3mm, and described air-conditioning sound mat thickness is 3-9mm; Described air-conditioning sound pad is by hot-forming.
For the effect making the utility model reach marketing, the material adopted all can be buied by market.Wherein the cotton layer of two component is made up of PP+PET, and wherein PP is polypropylene, and PET is PETG.
The beneficial effects of the utility model are: utilize two component cotton to have bulkiness strong, the sound insulation of sound-absorbing effect and PET Nomex and sound-absorbing effect, wherein PET also has excellent high-and low-temperature resistance performance, by rubber slab, both are combined to together, better can reach the effect of sound-absorbing, sound insulation and noise reduction, noise reducing effect reaches 95%, it is placed in outdoor machine of air-conditioner place, the noise produced when effectively decreasing operation of air conditioner.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 is the cotton layer of two component; 2 is rubber flaggy; 3 is anion PET acupuncture carpet veneer.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
The utility model provides a kind of air-conditioning sound pad, and as shown in Figure 1, air-conditioning sound pad is made up of trilaminate material compound, and it is the cotton layers of pair component at the middle and upper levels, and wherein the cotton layer fiber of two component is thinner, and its sound-absorbing effect is better, is original individual layer 2-3 times; Middle level is rubber slab, and lower floor is anion PET acupuncture carpet veneer, arranges anion PET Nomex and reduces noise on the one hand, improve ambient air quality on the other hand; The two component cotton layer thickness in upper strata is 1-3mm, can carry out increase and decrease thickness according to actual needs; Middle level rubber slab thickness is 1-3mm, can carry out increase and decrease thickness according to actual needs; Lower floor anion PET Nomex layer thickness is 1-3mm, can carry out increase and decrease thickness according to actual needs; Air-conditioning sound mat thickness is 3-9mm, can carry out the thickness changing product according to the model of product; Wherein air-conditioning sound pad is by hot-forming.
For the effect making the utility model reach marketing, the material adopted all can be buied by market.
It is strong that the utility model utilizes two component cotton to have bulkiness, the sound insulation of sound-absorbing effect and PET Nomex and sound-absorbing effect, wherein PET also has excellent high-and low-temperature resistance performance, by rubber slab, both are combined to together, better can reach the effect of sound-absorbing, sound insulation and noise reduction, noise reducing effect reaches 95%, it is placed in outdoor machine of air-conditioner place, the noise produced when effectively decreasing operation of air conditioner.
