Specific embodiments

[0031] In order to make the purpose, technical solutions and advantages of the present application clearer, the following further details the present application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] In an air-cooled unit, in order to effectively reduce the noise generated during the operation of the compressor, a sound insulation box is often used as a noise reduction measure. In a large air-cooled unit equipped with multiple compressors, considering maintainability, each of the multiple compressors is externally provided with a sound insulation box. Each sound insulation box includes at least six sheet metals, and the sheet metals are connected by bolts. After the compressor is hoisted, the installer enters the interior of the unit to surround multiple sheet metals around the compressor and fix them one by one with bolts. The number of sheet metals of multiple sound insulation boxes is large, and the installation efficiency by bolt connection is low. In addition, the pipelines inside the unit are staggered and the operation space is small, making it difficult for the installer to install. Not only is the operation restricted and the installation inconvenient, but there is also a risk of damaging the pipelines.

[0033] In view of the above problems existing in the related art, the embodiments of the present application provide a sound insulation box and an air-cooled unit. The sound insulation box can accommodate multiple compressors. The installation beam is installed in the middle of the bottom plate. Two groups of box bodies are respectively installed on the opposite sides of the installation beam in the first direction. The box bodies are inserted and connected to the bottom plate and the installation beam to reduce the usage amount of bolts and help improve the installation efficiency of the sound insulation box. The door panel is inserted into the bottom plate and fixed to the side of the box body away from the installation beam. In this way, the two groups of box bodies and the two groups of door panels are all installed and fixed on the opposite sides of the installation frame in the first direction. The installation is convenient. The installer does not need to enter the interior of the unit, avoiding operation in the narrow unit space and reducing the risks of personal injury and pipeline damage. In the present application, the bottom plate, the installation beam, the two groups of box bodies and the two groups of door panels enclose and define a accommodating space. The accommodating space can accommodate multiple compressors, saving space. Each door panel can be disassembled and assembled separately for a single compressor, which is convenient for maintenance.

[0034] Please refer to Figures 1 - 2 , Figure 1 which is a schematic structural diagram of a sound insulation box 1 according to an embodiment of the present application. Figure 2 which is a schematic installation structure diagram of a bottom plate 10 and an installation beam 20 according to an embodiment of the present application. The sound insulation box 1 includes a bottom plate 10, an installation beam 20, two groups of box bodies 30 and two groups of door panels 40. The bottom plate 10 is used for installing multiple compressors. The installation beam 20 is installed in the middle of the bottom plate 10. The two groups of box bodies 30 are respectively arranged on the opposite sides of the installation beam 20 in the first direction X. One group of box bodies 30 is located on one side of the installation beam 20 in the first direction X, and the other group of box bodies 30 is located on the other side of the installation beam 20 in the first direction X. Each group of box bodies 30 is respectively inserted into the bottom plate 10 and the installation beam 20, and one end of each group of box bodies 30 away from the installation beam 20 defines an installation opening with the bottom plate 10. Each group of door panels 40 is arranged corresponding to one of the installation openings. The door panel 40 is inserted into the bottom plate 10 and fixed to the box body 30 to seal the installation opening. In the embodiment of the present application, the bottom plate 10, the installation beam 20, the two groups of box bodies 30 and the two groups of door panels 40 enclose and define a accommodating space, and multiple compressors 2 are accommodated in the accommodating space.

[0035] Optionally, the sound insulation box 1 is integrally made of a metal material. For an air-cooled unit configured with multiple compressors 2, compared with using multiple independent sound insulation boxes, the sound insulation box 1 in the embodiment of the present application can reduce the usage amount of sheet metal parts and bolts and improve the installation efficiency.

[0036] The working principle of the air-cooled unit is based on the compression refrigeration cycle. Using the refrigerant as a carrier, through the forced heat exchange of the fan, it absorbs or discharges heat from the atmosphere to meet the refrigeration or heating requirements. In the air-cooled unit, the compressor 2 is connected in sequence with the evaporator, throttle, and condenser and together forms a circulation system. Among them, the compressor 2 is used to compress the refrigerant, and the compressor 2 has pipelines connected to the evaporator and condenser to send in or send out the refrigerant. Therefore, the sound insulation box 1 is configured with multiple openings to ensure that the pipelines of multiple compressors 2 can be connected to the evaporator and condenser.

[0037] Please refer to Figure 3 , Figure 3 which is a schematic diagram of the use of a sound insulation box 1 according to an embodiment of the present application. In an embodiment of the present application, the bottom plate 10 includes a main bottom plate 11 and an auxiliary plate 12. The main bottom plate 11 is used to be installed in the installation environment. The main bottom plate 11 is formed by splicing multiple bottom plate bodies. The main bottom plate 11 and the auxiliary plate 12 are arranged at an angle. The auxiliary plate 12 and the box body 30 are spliced to form a second opening 120. Part of the pipeline of the compressor 2 extends out of the sound insulation box 1 from the second opening 120 to be connected to the condenser or evaporator.

[0038] Optionally, the auxiliary plate 12 includes multiple pieces. The multiple auxiliary plates 12 are inserted and connected to the installation beam 20 and form multiple second openings 120 with the box body 30 for the pipelines of multiple compressors 2 to pass through. Taking the Figures 1 - 3 illustrated sound insulation box 1 as an example, two compressors 2 are arranged side by side along the first direction X in the sound insulation box 1. Correspondingly, the bottom plate 10 includes two auxiliary plates 12. The two auxiliary plates 12 are inserted into the installation beam 20 from opposite sides in the first direction X. Each auxiliary plate 12 forms a second opening 120 with a group of box bodies 30 respectively, so that the pipelines of the two compressors 2 can pass through the two second openings 120 one by one in the second direction Y. It should be noted that the bottom plate 10 of the embodiment of the present application is installed before the compressor 2 is installed. To ensure the connection stability of the bottom plate 10, the auxiliary plate 12 is connected to the main bottom plate 11 through fasteners. The second direction Y is perpendicular to the first direction X. It should be noted that the connection through fasteners in the embodiment of the present application can be through bolts or screws.

[0039] The installation beam 20 is used to support the box body 30 and provide an installation foundation for the box body 30. The installation beam 20 includes columns 21 and a cross beam 22. There are two columns 21. The two columns 21 are arranged side by side in the second direction and are connected to the bottom plate 10. The cross beam 22 is arranged on the two columns 21 and is connected to the end of the column 21 far from the bottom plate 10. In a specific implementation, to ensure the overall structural stability and weighing capacity of the installation beam 20, the column 21 is fixed to the bottom plate 10 through fasteners, and the cross beam 22 is fixed to the column 21 through fasteners.

[0040] After multiple compressors 2 are installed, the cabinet body 30 and the door panel 40 are installed. The cabinet body 30 includes side plates 31 and a top plate 32. There are two side plates 31, and the two side plates 31 are arranged side by side along the second direction Y and are inserted into the bottom plate 10. The top plate 32 is arranged opposite to the bottom plate 10 along the third direction Z and is disposed between the two side plates 31. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other pairwise. Among them, the top plate 32 and the two side plates 31 are respectively inserted into the installation beam 20, and the parts of the top plate 32, the two side plates 31, and the bottom plate 10 that are away from the installation beam 20 respectively define an installation opening. Compared with bolt connection, both the top plate 32 and the side plates 31 are connected to the installation beam 20 by insertion, and the operation is simpler and more convenient. The installer can insert and fix the top plate 32 and the side plates 31 from the opposite sides of the installation beam 20 along the first direction X, without the need to tighten multiple sheet metals from multiple directions, greatly reducing the installation difficulty and helping to improve the installation efficiency of the sound insulation box 1.

[0041] In the embodiment of the present application, the top plate 32 and the two side plates 31 are connected and jointly form the cabinet body 30. Among them, at least one of the side plates 31 and the top plate 32 has a first side matching portion 301, and the installation beam 20 has a second side matching portion 201. One of the first side matching portion 301 and the second side matching portion 201 is a first groove, and the other is a first protrusion. The first protrusion extends along the first direction X and is inserted into the first groove to ensure that the side plate 31 and / or the top plate 32 can be inserted and connected to the installation beam 20 from the first direction X, facilitating the installer to install from both sides of the installation beam 20, and then inserting the cabinet body 30 into the installation beam 20.

[0042] In an embodiment of the present application, both the two side plates 31 and the top plate 32 have a first side matching portion 301. The first side matching portion 301 is a first protrusion. The cross beam 22 and the two columns 21 have a second side matching portion 201. The second side matching portion 201 is a first groove. The two side plates 31 are respectively inserted into the two columns 21. Please refer to Figures 4 - 5 , Figure 4 For Figure 1 a partial enlarged schematic diagram of A in Figure 5 This is a schematic structural diagram of a cross beam 22 implemented in the present application. First grooves are provided on both opposite sides of the cross beam 22 along the first direction X. The top plate 32 is detachably connected to the two side plates 31 and is inserted into the cross beam 22. In this way, the top plate 32 and the two side plates 31 can both be detachably connected to the installation beam 20, and the connection between the cabinet body 30 and the installation beam 20 is more stable.

[0043] In another embodiment of the present application, a first side mating portion 301 is provided on one side of the side plate 31 close to the mounting beam 20. The mounting beam 20 has a second side mating portion 201. The two side plates 31 are inserted into the two columns 21 in one-to-one correspondence from the first direction X. The top plate 32 is connected to the two side plates 31, and the installation of the top plate 32 is simpler and more convenient.

[0044] Please continue to refer to Figure 4 , the top plate 32 is detachably connected to the two side plates 31. The side plate 31 has a first top mating portion 302, and the top plate has a second top mating portion 303. One of the first top mating portion 302 and the second top mating portion 303 is a second groove, and the other is a second protrusion. The second protrusion extends along the third direction Z and is inserted into the second groove to insert the top plate 32 into the side plate 31. Optionally, the side plate 31 includes a side plate body and a first flanging. The first flanging is angularly connected to the side plate body. The first flanging is provided with a first top mating portion 302 configured as a second groove. The top plate 32 has a second top mating portion 303 that is angularly connected to its plate surface. The second top mating portion 303 is configured as a second protrusion. The top plate 32 is inserted and connected to the side plate 31 along the third direction Z. A tight fit is formed between the top plate 32 and the side plate 31, improving the stability of the overall structure. The use of the insertion connection method helps to simplify the assembly and disassembly process of the top plate 32 and the side plate 31.

[0045] In the above embodiment, along the first direction X, the size of the second groove is larger than the size of the second protrusion. In this way, after the second protrusion and the second groove are inserted and matched, the top plate 32 can slide relative to the two side plates 31 along the first direction X, so as to facilitate the insertion connection of the top plate 32 to the cross beam 22.

[0046] It should be noted that the top plate 32 is provided with a first opening 320, and a part of the pipeline of the compressor 2 extends out of the top plate 32 from the first opening 320. In a specific implementation, multiple sub-plate bodies are spliced to form the top plate 32 to avoid interference between the top plate 32 and the pipeline of the compressor 2 during the installation process, and the first opening 320 is formed by splicing two adjacent sub-plate bodies. For any two adjacent sub-plate bodies, one sub-plate body has a first overlapping flanging, and the other sub-plate body has a second overlapping flanging. The first overlapping flanging overlaps on the second overlapping flanging and at least partially coincides with the second overlapping flanging along the second direction Y to connect the two sub-plate bodies.

[0047] Please refer to Figures 6 - 8 , Figure 6 is a schematic diagram of the installation structure of a support beam 50 according to an embodiment of the present application, Figure 7 is a schematic diagram of the structure of a side plate 31 according to an embodiment of the present application, Figure 8This is a schematic structural diagram of a daughter board body according to an embodiment of the present application. The sound insulation box 1 further includes a support beam 50. The support beam 50 extends along the second direction Y, and the support beam 50 is respectively installed on two side plates 31, and the top plate 32 is installed on the support beam 50. It can be seen that the support beam 50 and the cross beam 22 of the installation beam 20 are arranged opposite to each other along the first direction X. The support beam 50 is arranged on the side of the top plate 32 away from the cross beam 22 and is used to provide support for the top plate 32. The weight and load of the top plate 32 can be evenly distributed on the support beam 50 and then transmitted to the side plates 31, enhancing the structural stability of the overall sound insulation box 1.

[0048] The support beam 50 is installed between the top plate 32 and the side plates 31. Specifically, the surface of the side plate 31 includes a first step surface 311. The first step surface 311 includes two wall surfaces connected at an angle. The surface of the top plate 32 includes a second step surface 321. The second step surface 321 extends along the second direction Y, and the second step surface 321 is arranged opposite to the first step surface 311; the end of the support beam 50 abuts against the first step surface 311, and the second step surface 321 abuts against the support beam 50 to limit the position of the support beam 50 relative to the side plate 31 in the first direction X and the third direction Z, ensuring the stability of the support beam 50 in multiple directions and preventing it from displacing. The second step surface 321 includes a top plate body 322 and a first bending portion 323 connected at an angle. The first bending portion 323 extends along the second direction Y and is connected to the support beam 50 through a fastener to fix the position of the top plate 32 relative to the support beam 50.

[0049] Continue to refer to Figures 6 - 8 , the top plate 32 includes two end plates 324. At least one of the top plate body 322 and the first bending portion 323 is connected to the end plate 324 at an angle. The two end plates 324 are respectively arranged on opposite sides of the support beam 50 in the second direction Y and abut against the ends of the support beam 50 to limit the position of the support beam 50 relative to the side plate 31 in the second direction Y. In this way, the support beam 50 is completely limited, preventing the support beam 50 from displacing due to vibration during the use of the sound insulation box 1.

[0050] Optionally, after the side plate 31 is inserted and installed on the installation beam 20 and the bottom plate 10, the side plate 31 is fixed to the bottom plate 10 by a fastener. A second flanging is provided on the side of the side plate 31 close to the main bottom plate 11. The second flanging is parallel to the main bottom plate 11 and is fixed to the main bottom plate 11 by a fastener. In a specific implementation, the second flanging is located at one end of the side plate 31 away from the installation beam 20 to facilitate installation by installers.

[0051] Optionally, after the top plate 32 is inserted and installed on the installation beam 20 and the side plate 31, the top plate 32 is connected to the side plate 31 by fasteners. The first stepped surface 311 includes a third flanging portion connected to the side plate body at an angle. The top plate 32 further includes a second bending portion 325, and the second bending portion 325 is connected to the first bending portion 323 at an angle. Both ends of the second bending portion 325 are connected to the third flanging portion by fasteners. It can be seen that the second bending portion 325 and the third flanging portion are located at one end of the box body 30 away from the installation beam 20, which is convenient for installers to install.

[0052] As Figures 1 - 2 shown, the door panel 40 is arranged vertically and encapsulated in the installation opening. The bottom plate 10 has a first bottom matching portion 101, and the first bottom matching portion 101 is connected to the main bottom plate 11 at an angle. The door panel 40 has a second bottom matching portion. One of the first bottom matching portion 101 and the second bottom matching portion has a third groove, and the other has a third protrusion. The third protrusion is inserted into the third groove to insert the door panel 40 into the bottom plate 10, fixing the position of the door panel 40 relative to the bottom plate 10, effectively preventing the door panel 40 from tipping relative to the box body 30, or shifting or shaking within the installation opening, which is convenient for subsequent installation and fixation. Optionally, the first bottom matching portion 101 can also be configured as a stop flanging portion, which is connected to the main bottom plate 11 at an angle and is spaced from the box body 30. The second bottom matching portion of the door panel 40 is clamped between the stop flanging portion and the box body 30 to prevent the door panel 40 from tipping during installation.

[0053] The door panel 40 is fixed to the box body 30. The side plate 31 further includes two first installation flanging portions 312, which are arranged opposite to each other along the second direction Y and extend towards each other. The top plate 32 further includes a second installation flanging portion 326, and the second installation flanging portion 326 is connected to the second bending portion 325 at an angle. The second installation flanging portion 326 is located on the side of the installation opening away from the bottom plate 10. The second installation flanging portion 326 is arranged opposite to the main bottom plate 11 along the third direction Z and extends towards the main bottom plate 11. Among them, the two first installation flanging portions 312, the second installation flanging portion 326, and the first bottom matching portion 101 enclose and jointly define the installation opening. The door panel 40 is connected to the two first installation flanging portions 312 and the second installation flanging portion 326 by fasteners to fix the position of the door panel 40 relative to the box body 30 and close the installation opening. It can be seen that in the embodiment of the present application, the positions connected by fasteners are all arranged on the opposite sides of the sound insulation box 1 along the first direction, which is convenient for installers to install.

[0054] The door panel 40 includes multiple sub-door panels 41. The multiple sub-door panels 41 are arranged side by side in the second direction Y and jointly enclose the installation opening.
