Referring to Fig. 1 to Fig. 5, Fig. 1 is a structural schematic diagram of an embodiment of the utility model outdoor unit; Fig. 2 is a partial structural schematic diagram of the utility model outdoor unit; Fig. 3 is a structural schematic diagram of another embodiment of the utility model outdoor unit ; Figure 4 is a partial enlarged view at A in Figure 3 .

In the embodiment of the present utility model, the outdoor unit includes a casing 110, a compressor 160 and a wrapping layer 210, the compressor 160 is installed in the casing 110, and the wrapping layer 210 is wrapped around the shell of the compressor 160 body 151; the wrapping layer 210 includes a sound-absorbing layer, a sound-insulating layer, and a flame-retardant layer; the sound-absorbing layer and the sound-insulating layer are sequentially covered on the surface of the housing 151, and the sound-absorbing layer is bonded to the housing 151 , the flame-retardant layer is covered on the sound-absorbing layer and/or the sound-insulating layer.

Specifically, in this embodiment, the compressor 160 is a hermetic compressor 160, and the compressor 160 includes a casing 151, and an electric structural assembly and a compression structural assembly arranged inside the casing 151, wherein the electric structural assembly can generate The driving force, the compression structural component is connected to the above-mentioned electric structural component, which can suck, compress and discharge the fluid. The housing 151 is a cylindrical housing 151 , an air outlet is opened at one end of the housing 151 , and an air inlet is opened on a side wall of the housing 151 . After the wrapping layer 210 wraps the casing 151, the air inlet and the air outlet communicate with the outside through the refrigerant pipe. The chassis 110 includes a box body, a top cover, a frame and a bottom plate, and an air outlet grill 130 is arranged on the frame. The casing 110 is provided with components such as a heat exchanger 120 , a wind wheel, a motor, an electric control board, and a compressor 160 . Wherein, the wind wheel is arranged corresponding to the air outlet grille, which is beneficial to increase the flow of gas, so that the heat exchanger 120 can exchange heat with the surrounding air in time.

There are many ways for the wrapping layer 210 to wrap the casing 161 , such as glue, silica gel or foam material. It should be noted that wrapping in this embodiment refers to bonding and fixing the wrapping layer 210 and the casing 161 .

In this utility model, by bonding the wrapping layer 210 to the casing 151, the compression assembly of the compressor 160 body drives the casing 151 to generate vibrations, and the resistance to be overcome increases, which is equivalent to increasing the vibration damping of the casing 151, so that Reduce the vibration frequency of the compressor 160; when the vibration of the housing 151 is transmitted to the sound insulation layer and the sound absorption layer, the wrapping layer 210 converts the vibration energy into one or more of kinetic energy, thermal energy or potential energy, so that the sound absorption layer and the sound insulation layer Both layers can absorb and block the vibration of the compressor 160 at the same time; similarly, the sound-absorbing layer and the sound-insulating layer can also block and absorb the sound generated by the vibration of the compressor 160 at the same time, so that the wrapping layer 210 can reduce the vibration of the compressor 160 from the sound source and the sound itself. The noise generated by the body can effectively reduce the noise generated by the compressor 160 body, which is beneficial to reduce noise pollution; at the same time, by setting the sound insulation layer on the outside of the sound absorption layer, the sound waves will be absorbed by the sound insulation layer after passing through the sound absorption layer. The sound waves that block the return are absorbed by the sound-absorbing layer again, thus effectively reducing the transmission of sound waves.

The sound-absorbing layer and/or sound-insulating layer includes sound-absorbing cotton, and the sound-absorbing cotton has an expanded structure of Su Song (with several gaps inside), and the vibration generated by the compressor moves along with the gaps inside the sound-absorbing cotton after touching the sound-absorbing cotton. , in the process of moving, it is continuously absorbed by the sound-absorbing cotton around the gap, and the sound-absorbing cotton converts the absorbed vibration into heat energy; at the same time, the noise generated by the vibration of the compressor shell moves with the gap inside the sound-absorbing cotton. It is continuously absorbed by the sound-absorbing cotton around the gap, and is converted into heat energy for dissipation.

Referring to Table 1 and Figure 6, the sound-absorbing layer and/or the sound-insulating layer include a data table and a data graph of the sound-absorbing cotton. Among them, ① indicates the noise level of the outdoor unit when it is bare metal; ② indicates the noise level of the outdoor unit when the sound-absorbing layer and/or sound-insulating layer includes sound-absorbing cotton. Figure 6 is a comparison chart of the noise curve of the outdoor unit corresponding to Table 1. In particular, considering the noise of the outdoor unit of the inverter air conditioner, the heating noise is generally greater than the cooling noise, so this comparison data is the heating noise.

Table 1 Sound-absorbing layer and/or sound-insulating layer including sound-absorbing cotton

On the basis of the above embodiments, the sound-insulating layer and/or the sound-absorbing layer further includes a rubber layer, and the rubber layer covers the sound-absorbing cotton.

In this embodiment, the rubber layer can be a rubber skin, and the rubber layer wraps the compressor body and the sound-absorbing cotton. When the vibration generated by the casing passes through the sound-absorbing cotton, part of the vibration is absorbed by the rubber layer, and part of the vibration is absorbed by the rubber layer. Reflected back to the sound-absorbing cotton, the sound-absorbing cotton performs energy conversion processing on the reflected part of the vibration again. If there is still vibration that penetrates the sound-absorbing cotton and is transmitted to the shell, the shell will rebound part of the vibration to the sound-absorbing cotton again, and so on until the vibration is complete. All energy is converted into heat energy. In the same way, the noise generated by the shell and compression components penetrates the sound-absorbing cotton, meets the rubber layer, is partially absorbed by the rubber layer, and partly reflected back to the rubber layer, until the sound-absorbing cotton converts the energy of the noise into heat energy.

The elastic particles may include one or more of perlite particles, vermiculite particles, rubber particles and silica gel particles. The elastic powder 211 may include one or more of perlite powder, vermiculite powder, rubber powder and silica gel powder. Whether there is a gap between particles or between powder particles and powder particles, when the sound passes through the particle layer or powder layer, the sound wave will bypass the particle or powder and propagate in the channel formed by the above-mentioned gap connection In the process of sound wave propagation, its energy is absorbed by powder or particles, and powder or particles convert the ability of sound wave into one or more of potential energy, kinetic energy or thermal energy. Due to the large number of particles and powders, there are many channels through which the sound waves can be transmitted, so that the sound waves can fully contact the particles, which is conducive to increasing the attenuation efficiency of sound wave energy, thereby effectively reducing the transmission of noise. There is mutual extrusion and deformation between the elastic particles and the elastic powder 211, so that the elastic particles and the powder are squeezed and bonded to the housing 151, so that the elastic powder 211 and the particles are closely attached to the housing 151. When the housing 151 When the electric structural assembly and the compression structural assembly drive the housing 151 to vibrate, the resistance that the driving housing 151 needs to overcome to generate vibration increases, increasing the damping of the vibration of the housing 151, which can reduce the vibration frequency of the compressor 160; at the same time , the vibration of the shell 151 is transmitted through the elastic particles and powder in contact with it, and the vibration will drive the particles and powder to vibrate during the transmission process between the particles or between the powders, so that the particles and the powder are deformed, so that the particles and the powder Friction occurs between the particles, and even the particles and powders are displaced, so that the energy of vibration is converted into kinetic energy, potential energy (including elastic potential energy) and thermal energy, thereby effectively attenuating the energy of vibration, thereby reducing the energy generated by vibration transmission. noise.

Among them, ① indicates the noise level of the outdoor unit when it is bare metal; ② indicates the noise level of the outdoor unit when the sound-absorbing layer and/or sound-insulating layer includes rubber powder. Figure 7 is a comparison chart of the noise curve of the outdoor unit corresponding to Table 2. In particular, considering the noise of the outdoor unit of the inverter air conditioner, the heating noise is generally greater than the cooling noise, so this comparison data is the heating noise. The test condition is in the semi-anechoic chamber, the outdoor unit is outside the semi-anechoic chamber, and the indoor unit is inside the semi-anechoic chamber. The test conditions are 3°C outdoor and 20°C indoor.
