[0047] The air-conditioning outdoor unit involved in the utility model has at least two noise generating units, and the noise generating units include but are not limited to compressors, oil separators, air intake and exhaust pipes, electrical components and other noise generating components. In the present application, the oil separator, air intake and exhaust pipes, electrical components and other noise generating components are defined as the first noise generating unit, and the maximum noise source, such as a compressor, is defined as the second noise generating unit. In order to reduce the noise generated by the above-mentioned noise generating units and realize the stable operation of the air-conditioning outdoor unit in a low-noise environment, the utility model proposes a soundproof cover for the air-conditioning outdoor unit, which is configured as a double-layer soundproof cover, namely, includes a first soundproof cover and a second soundproof cover, wherein the first soundproof cover is configured to surround the first noise generating unit, and the second soundproof cover is configured to surround the second noise generating unit, and the first soundproof cover is configured to surround the second soundproof cover, that is, the second soundproof cover is configured in the first soundproof cover, thereby realizing a double-layer soundproof cover. By adopting the sound insulation cover proposed by the utility model, a double-layer sound insulation cover is provided for the air-conditioning outdoor unit, wherein the second sound insulation cover can isolate the maximum noise source of the air-conditioning outdoor unit, such as the noise generated by the compressor, and the first sound insulation cover can isolate the noise generated by other noise sources of the air-conditioning outdoor unit (such as air noise generated by the airflow of the unit and various noises such as electromagnetic noise generated by electrical components), and because the first sound insulation cover is arranged to surround the second sound insulation cover, the first sound insulation cover also plays a role in further reducing the maximum noise source of the air-conditioning outdoor unit, such as the noise generated by the compressor, thereby solving the problem of bad noise during the operation of the air-conditioning outdoor unit.

[0048] The first soundproof cover can be formed into a first fully enclosed space, and the second soundproof cover can be formed into a second fully enclosed space, thereby forming a double-layer fully enclosed space. The fully enclosed environment more effectively reduces the noise during the operation of the unit. Compared with the traditional air-cooled screw-type hot and cold water unit, the noise is reduced by more than 15dB.

[0049] The air conditioner outdoor unit provided by the present invention is described below in conjunction with exemplary embodiments of the present invention.

Figure 1 A soundproof enclosure 1 and a modular upper part 2 are shown. The modular upper part 2 is arranged above the soundproof enclosure 1. The connection of the soundproof enclosure 1 and the modular upper part 2 is described below with reference to the accompanying drawings.

[0050] Figure 2 A perspective view of a soundproofing enclosure 1 is shown. Figure 3 FIG. 1 shows an exploded view of the soundproof enclosure 1. Figure 2 and Figure 3 As shown, the soundproof cover 1 is configured to surround the noise generating unit of the air conditioner outdoor unit. The noise generating unit includes but is not limited to a compressor, an oil separator, an intake and exhaust pipe, electrical components and other noise generating components. The configuration of the soundproof cover 1 can effectively isolate the noise generated by the noise generating unit of the air conditioner outdoor unit. The soundproof cover 1 includes: a frame 17, a rear soundproof board 11, an upper soundproof board 12, a left soundproof board 13, a lower soundproof board 15, a right soundproof board 16, a front soundproof board 18 and internal functional components 14. The above-mentioned soundproof boards 11, 12, 13, 15, 16 and 18 are preferably in the form of sheet metal edge panels filled with sound insulation foam, which has a simple and reliable structure and low cost. The following will explain how each soundproof board is installed to the frame 17.

[0051] Figure 4 The frame 17 of the soundproof enclosure 1 is shown, which is used to support the internal functional components 14 such as the compressor, evaporator components, electric control box, inverter, pipelines and brackets inside the whole machine. The frame 17 is provided with a mounting guide, and the above-mentioned sound insulation boards 11, 12, 13, 15, 16 and 18 are installed and fixed on the mounting guide, so that the soundproof enclosure 1 forms a six-sided fully enclosed structure. Figure 4 As shown, the installation guide includes a front guide rail 8, a rear guide rail 5 and a base 10. The frame 17 also includes: a left crossbeam 6, a right crossbeam 7 and a column 9. The column 9 extends vertically between the front guide rail 8 and the base 10 and between the rear guide rail 5 and the base 10, respectively, and the column 9 is fixed to the front guide rail 8, the rear guide rail 5 and the base 10 by means of fasteners. The rear guide rail 5 and the front guide rail 8 have the functions of supporting and connecting the modular upper component 2 and fixing and installing the upper sound insulation board 12. The rear guide rail 5 and the front guide rail 8 are sheet metal structural members, which are fixed to the column 9 by fasteners (such as bolts).

[0052] like Figure 3 As shown, the soundproof cover 1 includes a rear soundproof board 11, a left soundproof board 13, a right soundproof board 16, and a front soundproof board 18 in four circumferential directions. These soundproof boards are fixed to the pillar 9, the front guide rail 5, and the rear guide rail 8 by fasteners (such as bolts).

[0053] like Figure 5 and Figure 6 As shown, the upper sound insulation board 12 can be inserted into the guide rail installation plane A (such as Figure 6 As shown in FIG. 1 ), the upper sound insulation board 12 and the frame 17 are then fastened by fasteners (such as bolts). Finally, the left crossbeam 6 and the right crossbeam 7 located on both sides of the frame 17 are used to limit the position. The installation method of the upper sound insulation board 12 of the soundproof cover 1 has the characteristics of simple and reliable structure, convenient installation and disassembly, and low implementation cost.

[0054] like Figure 8 and Fig. 9 As shown, the lower sound insulation board 15 is installed on the base rail 27 of the base 10. The base rail 27 is a U-shaped bent sheet metal part fixed to the base channel steel by welding. Fig. 9 As shown, the U-shaped groove B of the base rail 27 (such as Fig. 9 As shown in the figure, the lower sound insulation board 15 has a guide rail plane, and the lower sound insulation board 15 can be inserted into the guide rail installation plane piece by piece from both ends, and the lower sound insulation board 15 is fixed to the base guide rail 27 by fasteners (such as bolts).

[0055] By fully-enclosing the sound insulation panels on the six sides of the sound insulation cover 1 to the frame 17 of the sound insulation cover 1, a fully-enclosed sound insulation cover 1 is achieved, thereby further isolating the noise generated during the operation of the unit.

[0056] In order to further reduce the noise during the operation of the unit, the air conditioner outdoor unit proposed by the utility model is also provided with another sound insulation cover. Figure 7 Another soundproof cover for a compressor inside an air conditioner outdoor unit is shown to further reduce the noise generated by a large noise source such as the compressor. Figure 7As shown, another soundproof cover for the compressor includes a bracket 20, a rear side panel 19, a left side panel 21, a lower side panel 22, an upper side panel 23, a right side panel 24, and a front side panel 25. The side panels of the other soundproof cover for the compressor are mounted on the bracket 20 by means of fasteners (such as bolts), so that the second soundproof cover forms a fully enclosed space, further reducing the noise generated by large noise sources. The six side panels of the other soundproof cover for the compressor are composed of a front panel and an inner panel, and soundproof cotton material is clamped between the front panel and the inner panel. In addition, internal functional components 14, such as noise-generating units such as compressors, oil separators, and exhaust pipes that generate noise are wrapped with soundproof cotton, which, in conjunction with the soundproof cover 1 and another soundproof cover for the compressor, greatly reduce the noise during the operation of the unit. In addition, Figure 7 Also shown is a shock absorber for the compressor to reduce vibration of the compressor foot. Figure 7 As shown, the compressor foot is provided with a compressor shock absorber 26 for reducing the vibration of the compressor foot. The compressor shock absorber can be set as a spring shock absorber. The base 10 of the soundproof cover 1 can also be provided with a shock absorber, such as a spring shock absorber, to reduce the vibration noise of the whole machine.

[0057] Fig.10 A modular upper component 2 is shown. Fig.10 As shown, the modular upper component 2 includes a top cover component 3 and an upper frame 4. The upper frame 4 is a sheet metal component. Fig.11 As shown, the top cover component 3 is composed of an axial fan, a condenser component 31, a support member and an appearance panel, etc., which plays a role in cooling the refrigerant. The upper frame 4 for supporting the condenser component 31 includes a crossbeam and an intermediate column 30. The intermediate column 30 protrudes and extends vertically downward from the upper frame 4. The intermediate column 30 connects the modular upper component 2 and the soundproof cover 1 through fasteners (such as bolts), and the height of the intermediate column 30 can be adjusted according to the air intake demand of the top cover component 3. The air intake refers to the air volume entering the top cover component 3 through both sides of the condenser component 31. Affected by the space of the upper component 2, when the intermediate column 30 is high, the space between the upper component 2 and the soundproof cover 1 is large, and the air intake is large. On the contrary, when the intermediate column 30 is low, the air intake is small. The condenser component 31 has a built-in copper tube, and the refrigerant flows in the copper tube to play a cooling role. The gas distribution pipe 29 and the liquid pipe 28 are refrigerant flow pipes, which connect the refrigerant flow pipe in the soundproof cover 1 and the cooling pipe of the top cover component 3.

[0058] As shown in the embodiments of the present application, the unit as a whole has a strong modular expansion and generalization capability. Specifically, the length of the base 10, the left crossbeam 6, the right crossbeam 7, the column 9, the front guide rail 8 and the rear guide rail 5 of the frame 17 in the soundproof cover 1 can be extended or shortened according to the cooling demand. The cooling demand is related to many factors, such as the temperature difference between indoor and outdoor, the temperature to be reached, and the number of people and area indoors. The sound insulation panels on the six sides of the soundproof cover 1 can be adjusted in length, width and quantity according to demand. The number of top cover components 3 of the modular upper component 2 can be flexibly increased or decreased, and the length and height of the corresponding upper frame 4 can also be adjusted.

[0059] The rear guide rail 5, the front guide rail 8 and the base guide rail 27 composed of the U-shaped bent sheet metal parts of the soundproof cover 1 described in the above embodiment of the utility model are all made of sheet metal bent parts. Optionally, if the cost is not considered, the soundproof board can also be installed in the form of a combination of a linear guide rail and a slider. The combination of a linear guide rail and a slider as an installation guide is a prior art and will not be described in detail here.

[0060] Optionally, the same structural form of the six-sided fully enclosed soundproof cover 1 can be synonymously replaced by an external unit soundproof cover, a soundproof frame, etc.

[0061] By adopting the solution of the above-mentioned embodiment of the utility model, a double-layer sound insulation cover is provided for the air-conditioning outdoor unit, wherein the second sound insulation cover can isolate the maximum noise source of the air-conditioning outdoor unit, such as the noise generated by the compressor, and the first sound insulation cover can isolate the noise generated by other noise sources of the air-conditioning outdoor unit (such as air noise generated by the airflow of the unit and various noises such as electromagnetic noise generated by electrical components), and because the first sound insulation cover is arranged to surround the second sound insulation cover, the first sound insulation cover also plays a role in further reducing the maximum noise source of the air-conditioning outdoor unit, such as the noise generated by the compressor, thereby solving the problem of poor noise during the operation of the air-conditioning outdoor unit.

[0062] In addition, the first sound insulation cover and the second sound insulation cover of the sound insulation cover proposed in the utility model both adopt a fully enclosed structure. For the large-capacity air-cooled screw hot and cold water unit as an example of the utility model, compared with the traditional air-cooled screw unit, the noise value of the whole machine can be reduced by more than 15dB, thereby realizing the operation of the large-capacity unit under ultra-low noise conditions.

[0063] The structures of the sound insulation cover and the air-conditioning outdoor unit proposed in the utility model adopt a modular design. The sizes of the frame and the sound insulation board constituting the sound insulation cover and the sizes of the structural components of the air-conditioning outdoor unit can be adjusted as needed. It can adapt to units with different cooling capacities and different structural sizes, and has strong versatility and generalization capabilities.
