[0033] In the present application, by providing the mounting groove 11 on the inverter body 10, the fan assembly 20 is detachably mounted in the mounting groove 11, when the related components of the fan assembly 20 are damaged, the replacement can be simply and quickly realized without dismounting the external power line and the whole machine shell, and the maintenance efficiency of the fan assembly 20 of the inverter is improved. Wherein, the fan assembly 20 comprises a mounting bracket 21 and a fan 29 mounted on the mounting bracket 21, and the mounting bracket 21 is provided with a receiving cavity 22; the two ends of the connecting wire are connected to the fan 29 and the wiring port 121 respectively, and the connecting wire extends along the length direction of the mounting bracket 21 (such as the x direction in the figure) and is at least partially received in the receiving cavity 22. Figure 5 and Figure 7The connection wire extends along the length direction of the mounting bracket 21 and is at least partially accommodated in the accommodation cavity 22. In this way, the connection wire can be effectively accommodated without occupying other space positions in the inverter body 10, avoiding the connection wire being cut due to pulling during replacement of the fan assembly 20, and also avoiding the problem of twisting caused by the rotation of the fan blades of the fan 29 due to the redundancy of the connection wire; the working stability of the fan assembly 20 is improved to some extent, and the heat dissipation of the inverter body 10 is more favorable.

[0034] That is, the embodiment sets the accommodation cavity 22 on the mounting bracket 21, and the connection wire extends along the length direction of the mounting bracket 21 and is at least partially accommodated in the accommodation cavity 22. In this way, the connection wire can be effectively accommodated without occupying other space positions in the inverter body 10, avoiding the connection wire being cut due to pulling during replacement of the fan assembly 20, and also avoiding the problem of twisting caused by the rotation of the fan blades of the fan 29 due to the redundancy of the connection wire; the working stability of the fan assembly 20 is improved to some extent, and the heat dissipation of the inverter body 10 is more favorable.

[0035] In the embodiment, the fan assembly 20 includes a plurality of fans 29, and the plurality of fans 29 are sequentially and spacedly arranged along the length direction of the mounting bracket 21, so as to realize the ordered arrangement of the fans 29. For example, the number of the fans 29 can be 1, 2, 3, 4, etc., and the number of the fans 29 is determined according to the power of the inverter in actual production process, so as to realize the effective heat dissipation of the inverter. The connection wire is a plurality of connection wires, and the plurality of connection wires, the plurality of fans 29 and the plurality of wire ports 121 are one-to-one corresponding. In the application, the connection wire is a key to realize the electrical connection between the fan assembly 20 and the inverter. In actual installation process, attention should be paid to the accommodation and arrangement of the connection wire, so as to reduce the problem of the connection wire being cut due to pulling during maintenance or replacement of the fan assembly 20, and also reduce the problem of the normal work of the fan assembly 20 being affected due to the twisting problem between the fan blades of the fan 29 and the connection wire.

[0036] Specifically, in some embodiments of this application, the number of mounting cavities 23 along the length of the mounting bracket 21 can be 1, 2, 3, 4, etc. In actual production, the number of mounting cavities 23 is selected based on the specific power of the inverter. In this embodiment, the mounting cavity 23 closest to the receiving cavity 22 is designated as the first mounting cavity 231. Limiting structures 24 are provided between adjacent mounting cavities 23 and between the receiving cavity 22 and the first mounting cavity 231. The limiting structures 24 ensure neat wiring of the connecting wires and improve the installation stability of the connecting wires, making them less prone to falling off. When the fan assembly 20 is working, it will not affect the operation of the fan blades 29, reducing the occurrence of wire twisting. Furthermore, in this embodiment, when the fan assembly 20 needs maintenance or replacement, it can prevent the connecting wires from being cut due to tangled wires.

[0037] Optionally, the limiting structure 24 can be configured as one, two, three, four, etc., the specific number being determined according to the positioning and requirements of the connecting wires. Specifically, in some embodiments of this application, the limiting structure 24 can be disposed along the width direction of the mounting bracket 21 (e.g., Figure 5 and Figure 7 On the same side (in the y-direction), or separately on both sides of the mounting bracket 21 along the width direction. This application's Figure 7 The diagram shows the limiting structure 24 positioned on the same side along the width of the mounting bracket 21. This configuration not only ensures neat and aesthetically pleasing wiring of the connecting wires on the fan assembly 20, but also prevents wire tangling that could affect the rotation of the fan blades 29 due to messy wiring.

[0038] Optionally, the limiting structure 24 can be at least one of a groove, a wire clamp, a clamp, or a buckle. In this application, it is preferred that the limiting structure 24 be a groove, which allows the connecting wire to pass smoothly through the limiting structure 24 and be fixed on the limiting structure 24, thus ensuring the neatness of the connecting wire layout and improving the stability of the connecting wire.

[0039] In the embodiment, the limiting structure 24 between the accommodation cavity 22 and the first mounting cavity 231 can be arranged at a position extending along the length direction of the mounting bracket 21, or at another side of the mounting bracket 21 along the width direction, or at a position between the accommodation cavity 22 and the first mounting cavity 231. In the embodiment, it is preferred that the limiting structure 24 between the accommodation cavity 22 and the first mounting cavity 231 is arranged on the inner wall surface of the accommodation cavity 22, and a wire harness hole 210 is further arranged on the inner wall surface, a plurality of connecting wires are arranged in the wire harness hole 210 and fixed on the limiting structure 24 between the accommodation cavity 22 and the first mounting cavity 231, and the redundant part of each connecting wire is accommodated in the accommodation cavity 22, which not only ensures the neatness of the arrangement of the connecting wires, but also improves the stability of the connecting wires and prevents the connecting wires from falling off. When the fan assembly 20 is in operation, the connecting wires are less likely to fall off, and the occurrence of the wire twisting is avoided. In addition, the redundant part of the connecting wires is accommodated in the accommodation cavity 22, so that the redundant part of the connecting wires does not affect the rotation of the fan blades 29 and does not fall into the air duct to affect the normal operation of the fan assembly 20, and the use performance of the inverter is improved to a certain extent.

[0040] Referring to Figure 5 As shown in the figure, the first wiring terminal 12 is arranged near the slot end of the mounting groove 11. In actual work, after the connecting wires are neatly arranged through the limiting structure 24 on the mounting bracket 21, the redundant part of the connecting wires is accommodated in the accommodation cavity 22, and the plug of the connecting wire accommodated in the accommodation cavity 22 is inserted into the plurality of wiring ports 121 on the first wiring terminal 12 to realize electrical connection. In addition, a notch 212 is arranged on the side wall of the accommodation cavity 22 opposite to the first wiring terminal 12, which facilitates the relevant operation of the maintenance personnel during actual maintenance and replacement.

[0041] For example, the number of wiring ports 121 can be 1, 2, 3, 4, etc., and in actual production and processing, the number of wiring ports 121, connecting wires and fan blades 29 is one-to-one corresponding.

[0042] Referring to Figures 5 to 7As shown, in the embodiment, the mounting bracket 21 is slidably arranged in the mounting groove 11. In actual production and processing, a sliding groove is mounted in the mounting groove 11 on the inverter body 10, and a sliding rail is mounted on the mounting bracket 21, and the sliding groove and the sliding rail are guided and matched. In this way, the fan assembly 20 is detachably mounted in the mounting groove 11, facilitating the related cleaning, maintenance and replacement of the fan assembly 20 later, and the operation is simple, and the maintenance efficiency of the maintenance personnel is improved. Moreover, the two ends of the mounting bracket 21 are locked on the body 10 through the first limiting structure 25 and the second limiting structure 26, respectively, improving the mounting stability of the mounting bracket 21 on the body 10, avoiding the mounting bracket 21 from falling off the body 10 in the actual working process, and affecting the normal work of the inverter.

[0043] Alternatively, the first limiting structure 25 can be a clamping tongue and a clamping hole, can also be a limiting baffle, and can also be a limiting groove 211 and a limiting protrusion 101 matched with the limiting groove 211. In the embodiment, the first limiting structure 25 is preferably set as the limiting groove 211 and the limiting protrusion 101 matched with the limiting groove 211. One of the limiting grooves 211 is arranged on the bottom side wall of the mounting groove 11, and the other is arranged on the mounting bracket 21. In the embodiment, the limiting groove 211 is preferably arranged on the mounting bracket 21, and the limiting protrusion 101 is arranged on the bottom side wall of the mounting groove 11. Alternatively, the limiting groove 211 and the limiting protrusion 101 are connected by screws, which can avoid the problem that the fan assembly 20 falls off due to vibration in actual work, improve the connection strength of the fan assembly 20, and also reduce the vibration of the fan 29 and the noise generated by the vibration. The first limiting structure 25 improves the stability of the fan assembly 20.

[0044] Further, the second limiting structure 26 can be a clasp and a clamping tongue, or can be set as a threaded fastener 28 and the like. In the embodiment, the second limiting structure 26 is preferably set as a threaded hole 27 and a threaded fastener 28 matched therewith. The threaded hole 27 is arranged on the side wall of the body 10 close to the slot end of the mounting groove 11, and the threaded fastener 28 is rotatably arranged on the mounting bracket 21. The threaded hole 27 and the threaded fastener 28 are matched, which can make the fan assembly 20 more neat and beautiful near the side of the body 10.

[0045] Further, the threaded fastener 28 comprises a screw rod 281 and a nut 282 arranged at the end of the screw rod 281. The screw rod 281 extends along the length direction of the mounting bracket 21 and is arranged on the mounting bracket 21, which can lock the mounting bracket 21 on the inverter body 10. In addition, the nut 282 protrudes from the end of the mounting bracket 21 in the length direction, so that the nut 282 can serve as a handle to pull out the fan assembly 20. When the fan assembly 20 is maintained and replaced by the later maintenance personnel, the operation is simple, and the work efficiency is improved to a certain extent.

[0046] According to the above embodiment, it can be known that the inverter of the embodiment comprises a body 10, a fan assembly 20 and a connecting wire.
