Embodiment
Below with reference to the accompanying drawings and the present invention is described in detail in conjunction with the embodiments.It should be noted that do not conflicting
In the case of, the feature in following embodiment and embodiment can be mutually combined.
As shown in Figure 1, 2, the outdoor machine of air-conditioner denoising structure in the one of embodiment of the present invention includes sound absorbing layer 2 and multiple
Vibration-damped component 3, the sound absorbing layer 2 are arranged at the inner side of outdoor machine of air-conditioner housing 1, and between having between the sound absorbing layer 2 and the housing 1
Gap forms air layer 4.Sound absorbing layer 2 is used for the main noise for absorbing outdoor machine of air-conditioner；Meanwhile have between sound absorbing layer 2 and the housing 1
Air layer 4, air layer 4 can increase soundproof effect, lift low-frequency range sound-absorption coefficient.Multiple vibration-damped components 3 are positioned apart from
Between the sound absorbing layer 2 and the housing 1.When sound absorbing layer 2 is hardened in low temperature environment, the vibration of calculation for pipelines system of compressor passes
Sound absorbing layer 2 is handed to, by the vibration damping of vibration piece, sheet metal component rigid plane that will not be directly with housing 1 acts on, so as to avoid phase
The extraordinary noise answered.As can be seen here, the outdoor machine of air-conditioner denoising structure in the present embodiment improves low frequency range noise level, lifts air-conditioning
Outer machine full frequency band noise noise reduction.
In order to form rational air layer 4, the vibration-damped component 3 is preferably bar shaped.Because the layout of vibration-damped component 3 directly affects
