Detailed Implementation

[0045] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, "linking" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0047] In the description of embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0048] Please refer to Figures 1-10 , Figure 1 This is a schematic diagram of the structure of the first type of electrical device provided in the embodiments of this application; Figure 2 for Figure 1 Schematic diagram of the structure of the medium-sized wind turbine module; Figure 3 for Figure 2 Exploded view; Figure 4 A cross-sectional view of the part perpendicular to the second direction; Figure 5 This is a structural schematic diagram of an air guide module; Figure 6 for Figure 5 A simplified structural diagram from a third-party Z-direction perspective; Figure 7 for Figure 6 A simplified structural diagram of a modified design; Figure 8 This is a partial structural diagram of another type of air guide module, in which some of the rectifier components inside the air guide tube are omitted; Figure 9 for Figure 5 Cross-sectional view from the perspective of PP; Figure 10 This is a structural diagram of the base frame module.

[0049] like Figure 1 As shown, this application embodiment provides an electrical device 100, which may be, for example, an inverter, an energy storage cabinet, an energy storage converter, etc., including a chassis 1000 and a fan module 2000.

[0050] In the electrical equipment 100, components such as the fan module 2000 can be directly or indirectly installed in the chassis 1000 for integrated assembly. The chassis 1000 provides protection for the internal components, reducing the impact of external moisture and dust. Simultaneously, the chassis 1000 largely determines the external shape of the electrical equipment 100. In this embodiment, the external shape of the chassis 1000 is not explicitly limited; in practical applications, those skilled in the art can choose according to specific needs, as long as it meets the requirements. For example, the chassis 1000 can be a triangular prism, cuboid, cylinder, or other three-dimensional structure.

[0051] In this embodiment, the fan module 2000 can be installed on the wall of the housing 1000. In this case, the fan module 2000 can draw air directly from the outside of the electrical equipment 100, without needing to add an additional air inlet to the wall of the housing 1000. The structure of the housing 1000 can be relatively simple, and the connection and fixation between the fan module 2000 and the housing 1000 can be easily achieved. The connection and fixation method between the fan module 2000 and the housing 1000 can be, for example, a screw connection, etc., and is not limited here, as long as it meets the relevant requirements such as connection reliability.

[0052] like Figure 2 and Figure 3 As shown, the fan module 2000 includes a base frame module 2100, a fan module 2200, and an air guide module 2300. The base frame module 2100 is the basic module of the fan module 2000. Both the fan module 2200 and the air guide module 2300 can be installed on the base frame module 2100 for integrated assembly. Furthermore, the fan module 2000 can be connected to the chassis 1000 via the base frame module 2100.

[0053] The fan module 2200 includes at least two fans 2211 to provide stronger wind power.

[0054] In the implementation of the attached diagram, as follows: Figure 3 As shown, the fan module 2200 may include two fan groups 2210, which may be arranged along the second direction Y. Each fan group 2210 may include three fans 2211, which may be arranged along the first direction X. The first direction X and the second direction Y may be set at an angle, such as 90 degrees. Furthermore, this embodiment also defines a third direction Z. Either the first direction X or the second direction Y may form an angle with the third direction Z, such as 90 degrees. Specifically, the third direction Z may be the axial direction of the fan 2211.

[0055] It should be understood that the above description of the specific structural form of the wind turbine module 2200 is mainly based on... Figure 3 The illustrations provided are for illustrative purposes only and should not be construed as limiting the scope of the fan module 2000 provided in this application. In other implementations of this application, the fan module 2200 may also employ other structural forms. For example, the fan module 2000 may include at least three fan groups 2210. Alternatively, each fan group 2210 may include two fans 2211, or each fan group 2210 may include at least four fans 2211. Furthermore, in each fan group 2210, at least two fan groups 2210 may include different numbers of fans 2211.

[0056] The air guide module 2300 is located on one axial side of the fan module 2200, specifically on the air inlet side of the fan module 2200. That is, in the direction of airflow, the air guide module 2300 is upstream of the fan module 2200, and the airflow can first pass through the air guide module 2300 and then flow into the fan module 2200. The airflow direction can be found in [reference needed]. Figure 4 As shown by the hollow arrow in the image.

[0057] Combination Figure 5The air guiding module 2300 includes a panel 2310, an air guiding duct 2320, and a shielding part 2330. The normal direction of the panel 2310 can be the aforementioned third direction Z. The air guiding duct 2320 is located on the side of the panel 2310 away from the fan module 2200 and can extend a certain length on the side away from the fan module 2200. The number of air guiding ducts 2320 is the same as that of the fans 2211, and each air guiding duct 2320 and each fan 2211 is arranged in a one-to-one correspondence so as to guide air to each fan 2211 in a one-to-one correspondence. The shielding part 2330 is located between adjacent air guiding ducts 2320 and is used to at least partially shield the gap between adjacent air guiding ducts 2320.

[0058] By adopting the above solution, the air guide module 2300 of the fan module 2000 provided in this application embodiment is provided with a shielding part 2330. The shielding part 2330 can shield the gap between adjacent air guide ducts 2320, which can reduce the pressure loss of the incoming air and reduce the possibility of eddies generated in the gap between adjacent air guide ducts 2320. This is beneficial to improve the airflow field, thereby reducing the noise during the operation of the fan module 2000 and improving the user experience.

[0059] Here, the embodiments of this application do not limit the specific structural form of the air guide 2320. In practical applications, those skilled in the art can select according to specific needs, as long as it meets the requirements of use. For example, the cross-section of the air guide 2320 perpendicular to the axial direction can be various shapes such as circular, elliptical, and square. As another example, each air guide 2320 can be independent of each other, that is, each air guide 2320 can be non-contacting. In this case, the gap between adjacent air guides 2320 can be relatively large; or, as... Figures 5-8 As shown, two adjacent air guide ducts 2320 can also contact each other. In this case, the gap between adjacent air guide ducts 2320 can be relatively small.

[0060] Furthermore, this application embodiment does not limit the aforementioned shielding portion 2330 to be specifically located between several adjacent air guide ducts 2320. In practical applications, those skilled in the art can determine this based on the arrangement of each air guide duct 2320. For example, see... Figure 6 The shielding part 2330 provided in area A can be located in the gap between two adjacent air guide ducts 2320, and the shielding part 2330 provided in area B can be located in the gap between four adjacent air guide ducts 2320. For example, see... Figure 7 The shielding part 2330 set in area C can be the gap between three adjacent air ducts 2320.

[0061] It is understood that the above description of the relative positional relationship between the air guide module 2300 and the fan module 2200 is merely an exemplary illustration made in conjunction with the accompanying drawings of this application embodiment, and should not be construed as limiting the scope of implementation of the fan module 2000 and electrical equipment 100 provided in this application embodiment. Under the condition of satisfying the function, the air guide module 2300 and the fan module 2200 may also have other positional relationships. For example, the air guide module 2300 may be located on one axial side of the fan module 2200, specifically on the air outlet side of the fan module 2200. That is, in the direction of airflow, the air guide module 2300 may be located downstream of the fan module 2200, and the air may first flow through the fan module 2200 and then into the air guide module 2300. In this case, the air guide module 2300 can improve the airflow field at the outlet, which can also reduce the noise during the operation of the fan module 2000. For example, the number of air guide modules 2300 can also be two. The two air guide modules 2300 can be located on both sides of the axial direction of the fan module 2200. In this case, air guide modules 2300 can be set on both the air inlet side and the air outlet side of the fan module 2200, which can achieve better noise suppression.

[0062] In some implementations, such as Figure 5 and Figure 9 As shown, the side of the shield 2330 facing away from the panel 2310 and the end of the air duct 2320 facing away from the panel 2310 can be flush.

[0063] With this configuration, the shielding part 2330 can provide better shielding between adjacent air ducts 2320. When the air guide module 2300 is located on the air inlet side of the fan module 2200, the shielding part 2330 can better block the air inlet, allowing more air to flow into the air duct 2320. This can reduce the possibility of eddies generated between adjacent air ducts 2320, as well as the resulting problems of poor airflow field, high noise, and poor user experience.

[0064] Furthermore, by setting the side of the shielding part 2330 away from the panel 2310 to be flush with the end of the air guide tube 2320 away from the panel 2310, it is possible to prevent the shielding part 2330 from protruding from the air guide tube 2320 in the direction away from the panel 2310. This allows the size of the air guide module 2300 in the normal direction (i.e., the third direction Z) of the panel 2310 to be relatively small, thereby reducing the installation space occupied by the air guide module 2300 and facilitating the installation and fixation of the air guide module 2300.

[0065] In some implementations, such as Figure 8 As shown, the side of the shield 2330 facing away from the panel 2310 may include an air guide surface 2331.

[0066] Along the direction away from the panel 2310, the air guide surface 2331 may protrude from the end of the air guide tube 2320 away from the panel 2310, and at least a partial area of ​​the air guide surface 2331 may form an angle with the normal of the panel 2310.

[0067] When the air guide module 2300 is located on the air inlet side of the fan module 2200, the shielding part 2330 not only has the aforementioned technical effect of shielding the gap between each air guide duct 2320, but also has the effect of guiding the air, which can better guide the air into the air guide duct 2320 and reduce the air inlet resistance to a greater extent, reduce the pressure loss of the air inlet, thereby better improving the air inlet flow field and more effectively reducing the air inlet noise.

[0068] When the air guide module 2300 is located on the air outlet side of the fan module 2200, the above-mentioned air guide surface 2331 can also reduce the accumulation of air on the side of the shield 2330 away from the panel 2310, which can better reduce the generation of eddies and improve the air outlet flow field of the fan module 2000, thereby better suppressing the air outlet noise.

[0069] In some implementations, such as Figure 9 As shown, a gap can be provided between the shielding part 2330 and the panel 2310, so that a cavity 2300A can be formed between the shielding part 2330 and the panel 2310. The shielding part 2330 can be made of... Figure 9 The flat plate structure shown can also be adopted. Figure 8 In summary, the curved panel structure shown can be such that the cavity 2300A described above can be formed between the shielding part 2330 and the panel 2310.

[0070] When the air guide module 2300 is disposed on the air inlet side of the fan module 2200, the shielding part 2330 may be located upstream of the panel 2310. The panel 2310 may also be provided with a through hole 2312A, which may be connected to the cavity 2300A. Through the cooperation of the through hole 2312A and the cavity 2300A, a Helmholtz resonant cavity can be formed in the air guide module 2300, which can effectively suppress noise of a specific frequency. For example, it can effectively suppress the blade passing frequency (BPF) noise of the fan 2211, thereby reducing the noise of the fan module 2000 provided in this embodiment during operation to a greater extent and improving the user experience.

[0071] In this embodiment, the shielding part 2330 and the air guide duct 2320 can be a one-piece molded structure. The one-piece molding process can be, for example, one-piece injection molding or one-piece casting, for convenient manufacturing. Figure 9 The panel 2310 may include a main plate portion 2311 and a sealing plate portion 2312; the main plate portion 2311 and the air guide duct 2320 may also be an integrally formed structure; the sealing plate portion 2312 may be connected to the main plate portion 2311, and the specific connection method may be welding, bonding, etc. The sealing plate portion 2312 may be arranged opposite to the shielding portion 2330 along the third direction Z, and the cavity 2300A may be formed between the shielding portion 2330, the air guide duct 2320 and the sealing plate portion 2312, and the aforementioned through hole 2312A may be provided in the sealing plate portion 2312.

[0072] As can be seen, the above description of the specific structural form of the air guide module 2300 is merely an exemplary illustration made in conjunction with the accompanying drawings of this application embodiment, and it cannot be used as a limitation on the implementation scope of the fan module 2000 provided in this application embodiment. In some other implementations of this application embodiment, the air guide module 2300 may also adopt other structural forms. For example, the panel 2310 may also be an integral structure. In this case, the air guide duct 2320 and the shielding part 2330 may be set as separate structures, or the air guide duct 2320 and the panel 2310 may be set as separate structures.

[0073] Here, the embodiments of this application do not limit the volume of the cavity 2300A, and the axial and radial dimensions of the through hole 2312A. In practical applications, those skilled in the art can determine the dimensions based on the frequency of the vibration noise to be eliminated and the formula for calculating the resonance frequency of the Helmholtz resonant cavity.

[0074] In addition to the above-mentioned implementation method of setting the air guide module 2300 on the air inlet side of the fan module 2200, in this embodiment of the application, the air guide module 2300 can also be set on the air outlet side of the fan module 2200. In this case, the shielding part 2330 can be located downstream of the panel 2320, and the aforementioned through hole 2312A can be set on the shielding part 2330.

[0075] In addition, in some other implementations of the embodiments of this application, the cavity 2300A may not exist. In this case, the shielding part 2330 can be a filling structure and can fill the gap between adjacent air guides 2320.

[0076] In some implementations, such as Figure 5 As shown, the air guide module 2300 may also include a rectifier component 2340.

[0077] The rectifier 2340 can be located inside the air duct 2320. The rectifier 2340 can adjust the airflow field again before the air enters the fan module 2200 to improve the uniformity of the airflow and suppress aerodynamic noise to a greater extent, thereby achieving the technical purpose of reducing noise and improving user experience.

[0078] Here, the embodiments of this application do not limit the specific structural form of the above-described rectifier component 2340. In practical applications, those skilled in the art can determine it according to specific needs, as long as it can meet the requirements of use. For example, the rectifier component 2340 can be a fairing, an air intake grille, etc. As another example, the fairing 2340 can be a one-piece structure.

[0079] In some implementations, such as Figure 10 As shown, the base module 2100 may be provided with a slot 2120, and the panel 2310 is configured to be plugged into the slot 2120 to facilitate the connection between the panel 2310 and the base module 2100.

[0080] In practical applications, after the panel 2310 is inserted into the slot 2120 of the base frame module 2100, it can also be equipped with connecting parts in the form of screws, rivets, etc., and then the panel 2310 and the base frame module 2100 can be connected through the connecting parts. In this way, the connection reliability between the air guide module 2300 and the base frame module 2100 can be improved to a greater extent, thereby reducing the possibility of the air guide module 2300 shaking relative to the base frame module 2100.

[0081] It is understood that, in addition to the above-mentioned plug-in implementation method, in some other implementation methods of the embodiments of this application, the panel 2310 can also be connected to the base frame module 2100 using other connection methods, as long as the relevant requirements such as connection reliability are met. For example, the panel 2310 can be directly connected to the base frame module 2100 using connectors such as screws or rivets. Alternatively, the panel 2310 can also be connected to the base frame module 2100 using connection methods such as welding, bonding, or snap-fit.

[0082] The base module 2100 can also be provided with an air outlet 2110, which can be set to correspond with the fan 2211 to realize the air outlet of the fan 2211.

[0083] In some implementations, such as Figures 2-4 As shown, the fan module 2000 may also include a noise reduction module 2400.

[0084] The silencing module 2400 can be installed on the base frame module 2100, and the silencing module 2400 can be located at least partially in the circumferential direction of the fan module 2200. The silencing module 2400 can further reduce the noise during the operation of the fan module 2000, especially broadband noise, thereby greatly improving the user experience. It should be understood that the circumferential direction here specifically refers to the direction around the axial direction of the fan module 2200.

[0085] Combination Figure 10 The base module 2100 may be equipped with a quick-release connector 2130, and the silencing module 2400 may be connected through the quick-release connector 2130 to enable quick installation or removal of the silencing module 2400.

[0086] Here, the embodiments of this application do not limit the specific structural form of the quick-release connector 2130 described above. In practical applications, those skilled in the art can select according to specific needs, as long as the usage requirements are met. For example, the quick-release connector 2130 may include a columnar body and a spring pin. The spring pin can be installed on the columnar body, and the silencing module 2400 may be provided with a locking hole. During installation, the silencing module 2400 can be inserted into the base frame module 2100. Through the cooperation of the spring pin and the locking hole, the installation, locking, or removal of the silencing module 2400 can be quickly achieved. As another example, the quick-release connector 2130 may also be a magnetic connector, so as to achieve quick installation and removal of the silencing module 2400 by magnetic attraction.

[0087] It can be seen that, in addition to the above-mentioned implementation of setting the quick-release connector 2130, in some other implementations of the embodiments of this application, the silencing module 2400 and the base frame module 2100 can also be connected by other connection methods, as long as they can meet the requirements of use. For example, the silencing module 2400 and the base frame module 2100 can also be connected by welding, bonding, screw connection, riveting, etc.

[0088] Furthermore, this application embodiment does not limit the specific type of the silencing module 2400. In practical applications, those skilled in the art can select according to specific needs, as long as it meets the requirements of use. For example, the silencing module 2400 can be any one or a combination of several of the following: a micro-perforated plate silencer, an expansion cavity silencer, a metamaterial silencer, and sound-absorbing material 2420. For example, see... Figure 3The silencing module 2400 may include a micro-perforated plate silencer and a sound-absorbing material 2420. The micro-perforated plate silencer may include a micro-perforated plate 2410. The sound-absorbing material 2420 may be, for example, sound-absorbing cotton. The sound-absorbing material 2420 may be placed in the back cavity of the micro-perforated plate silencer. In this way, the high-frequency noise during the operation of the fan module 2000 can be better eliminated. The aperture and thickness of the micro-perforated plate 2410 may be adjusted as needed.

[0089] Please refer to Figures 11-13 , Figure 11 This is a schematic diagram of the structure of the second type of electrical equipment provided in the embodiments of this application; Figure 12 Figure 11 Schematic diagram of the structure of the medium-sized wind turbine module; Figure 13 for Figure 12 Exploded view.

[0090] In some implementations, such as Figures 11-13 As shown, the fan module 2200 may also include only one fan array 2210 to reduce the space occupied by the fan module 2200 in the second direction Y and to simplify the structure of the fan module 2200.

[0091] In some implementations, such as Figures 11-13 As shown, the fan module 2000 may also exclude the silencer module 2400. In this case, the structure of the fan module 2000 can be simpler, the cost can be lower, and the installation space occupied by the fan module 2000 can be relatively smaller, making it easier to install.

[0092] After testing, in use Figures 11-13 After the fan module 2000 is shown, the second-order BPF noise is reduced by about 2 dBA, which can significantly improve the user experience.

[0093] Please refer to Figure 14 and Figure 15 , Figure 14 This is a schematic diagram of the structure of the third type of electrical equipment provided in the embodiments of this application; Figure 15 for Figure 14 Cross-sectional view;

[0094] In some implementations, such as Figure 14 and Figure 15As shown, the fan module 2000 can also be installed inside the housing 1000. In this case, the housing 1000 can be provided with an air inlet 1100, through which the fan module 2000 draws air. In this implementation, the axis of the air inlet 1100 and the axis of the fan 2211 can be parallel, and the air can be directly introduced into the fan module 2000 through the air inlet 1100 without any turning. The airflow direction can be referred to... Figure 15 As shown by the hollow solid line arrow in the image.

[0095] The electrical equipment 100 may also include a noise reduction module 2400, which may be installed on the base frame module 2100 and may extend to both sides of the fan module 2200 along the axial direction, thereby achieving a more significant noise reduction effect.

[0096] Please refer to Figures 16-18 , Figure 16 This is a schematic diagram of the structure of the fourth type of electrical equipment provided in the embodiments of this application; Figure 17 for Figure 16 Cross-sectional view; Figure 18 for Figure 17 A schematic diagram of the structure of a medium-sized wind turbine module.

[0097] In some implementations, such as Figures 16-18 As shown, the axial direction of the air inlet 1100 and the axial direction of the fan 2211 can be set at an angle, but this angle is not equal to 90 degrees; that is, the axial direction of the air inlet 1100 and the axial direction of the fan 2211 do not have to be perpendicular. In this case, after the air enters from the air inlet 1100, it needs to be redirected before flowing to the fan module 2200. The airflow direction can be referenced... Figure 17 As shown by the hollow solid line arrow in the image.

[0098] Please refer to Figures 19-21 , Figure 19 This is a schematic diagram of the structure of the fifth type of electrical equipment provided in the embodiments of this application; Figure 20 for Figure 19 Cross-sectional view in one direction; Figure 21 for Figure 19 A cross-sectional view from another direction.

[0099] In some implementations, such as Figures 19-21 As shown, the axial direction of the air inlet 1100 and the axial direction of the fan 2211 can be set at an angle, which can be equal to 90 degrees, that is, the axial direction of the air inlet 1100 and the axial direction of the fan 2211 can be perpendicular. In this case, after the air enters from the air inlet 1100, it needs to turn 90 degrees before flowing to the fan module 2200. The airflow direction can be referred to... Figure 20 As shown by the hollow solid line arrow in the image.

[0100] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
