However, rainwater and dust often enter the interior of the wind turbine frequency converter through these ventilation holes, affecting its normal operation. Utility Model Content

[0003] The main purpose of this utility model is to propose a heat dissipation and dust prevention device for wind power frequency converters, which aims to solve the problem that rainwater and sand often enter the interior of wind power frequency converters through the heat dissipation holes.

[0004] To achieve the above objectives, the wind power inverter heat dissipation and dust prevention device proposed in this utility model includes: Inverter body; and The louver structure is located on the side of the inverter body. The louver structure includes a frame and multiple air guides. The multiple air guides are spaced apart in the frame, and there is a heat dissipation channel between two adjacent air guides. Each air guide is fixed to the frame at an angle downwards.

[0005] In some embodiments, each of the air guide vanes includes a guide section, a transition section, and a baffle section connected in sequence. The guide section is connected to the frame, the transition section connects the guide section and the baffle section, and the baffle section is bent downwards into an "S" shape.

[0006] In some embodiments, the bends of the baffle segment have rounded corners.

[0007] In some embodiments, the air guide section and the frame are inclined at an angle, the angle ranging from 25 degrees to 40 degrees.

[0008] In some embodiments, each of the guide vanes is a folded, integrated structure.

[0009] In some embodiments, the frame is fixed to the side of the inverter body by screws.

[0010] In some embodiments, the wind power inverter heat dissipation and dust prevention device further includes a dustproof top cover, which is disposed on the top of the inverter.

[0022] Wind turbine frequency converters generate heat during operation. To effectively dissipate heat and ensure stable operation, ventilation holes are typically installed to cool the converter. However, rainwater and dust often enter the interior of the wind turbine frequency converter through these ventilation holes, affecting its normal operation.

[0023] This utility model proposes a heat dissipation and dust prevention device for wind power frequency converters. Please refer to [link / reference]. Figure 1The wind power inverter heat dissipation and dust prevention device proposed in this utility model includes: Inverter body 10; and The louver structure 20 is located on the side of the inverter body 10. The louver structure 20 includes a frame 21 and multiple guide vanes 22. The multiple guide vanes 22 are spaced apart on the frame 21, and there is a heat dissipation channel 220 between two adjacent guide vanes 22. Each guide vane 22 is fixed to the frame 21 at an angle downwards.

[0024] The number of guide vanes 22 is multiple. The multiple guide vanes 22 are spaced apart to form heat dissipation channels 220.

[0025] The technical solution of this utility model adopts a louver structure 20 installed on the side of the inverter body 10. The louver structure 20 includes a frame 21 and multiple guide vanes 22. The multiple guide vanes 22 are spaced apart on the frame 21, and there is a heat dissipation channel 220 between adjacent guide vanes 22, which facilitates the dissipation of heat through the heat dissipation channel 220, thereby achieving the function of heat dissipation. Each guide vane 22 is fixed to the frame 21 at an angle facing downwards, so that when rainwater falls on the guide vane 22, the outer surface of the guide vane 22 flows downwards until it flows to the ground, thereby preventing rainwater from entering the interior of the inverter. In addition, a lot of external sand and dust will be blocked by the guide vanes 22, making it difficult for them to enter the interior of the inverter, thus reducing the occurrence of sand and dust being directly blown into the interior of the inverter.

[0026] Furthermore, each guide vane 22 can be fixed to the frame 21 by welding.

[0027] In one embodiment, please refer to Figure 2 and Figure 3 Each guide vane 22 includes a guide section 221, a transition section 222 and a baffle section 223 connected in sequence. The guide section 221 is connected to the frame 21. The transition section 222 connects the guide section 221 and the baffle section 223. The baffle section 223 is bent downwards into an "S" shape.

[0028] The guide vane 22 forms a three-stage settling zone through the air guide section 221, the transition section 222 and the baffle section 223, so that sand or rainwater can be blocked by the guide vane 22 and can flow down along the shape of the outer surface of the guide vane 22, instead of being blown into the inside of the frequency converter, thereby improving the dustproof and rainproof performance of the frequency converter.

[0029] Furthermore, a dust filter can be installed on the side of the guide vane 22 facing the inside of the frequency converter, and the dust filter can be detachably connected to the frame 21. This invention effectively prevents external dust and particles from entering the interior of the frequency converter through the guide vane 22 and the dust filter.

[0030] Among them, the bend of the baffle section 223 has a rounded corner structure.

[0031] In one embodiment, at least five guide vanes 22 are mounted on the frame 21. The end of the bottommost guide vane 22 may be exposed relative to the outer surface of the frame 21 so that rainwater and dust can fall to the ground along the end of the guide vane 22.

[0032] The spacing between two adjacent guide vanes 22 is usually set between 25mm and 45mm to ensure smooth airflow while effectively preventing sand and dust from being blown directly into the inverter.

[0033] In one embodiment, the air guide section 221 and the frame 21 have an inclination angle, the angle of which ranges from 25 degrees to 40 degrees.

[0034] In one embodiment, each guide vane 22 is a folded integrated structure. The guide vane 22 can be fixed to the frame 21 by welding, so that the guide vane 22 and the frame 21 are fixedly connected.

[0035] The guide vane 22 can be formed by stamping.

[0036] In some embodiments, the frame 21 is fixed to the side of the inverter body 10 by screws, thereby facilitating the removal of the entire louver structure 20 from the side of the inverter or the installation of the entire louver structure 20 onto the side of the inverter.

[0037] In another embodiment, please refer to Figure 4 and Figure 5 The wind power inverter heat dissipation and dust prevention device also includes a dustproof top cover 30, which is located on the top of the inverter.

[0038] Specifically, the dust cover 30 includes a support foot 31 and a cover body 32. The cover body 32 has two inclined slopes 320 that protrude outward from each other. The support foot 31 supports the cover body 32 on the top of the inverter body 10.

[0039] In one embodiment, dust and rainwater can slide off the dust cover 30.

[0040] The dust cover 30 can be made of materials such as aluminum alloy, galvanized steel sheet, or stainless steel, which have the characteristics of corrosion resistance, strength and lightweight.

[0041] Specifically, two inclined slopes 320 meet at the center of the top of the inverter body 10 to form a ridge-like structure. The included angle between the two inclined slopes 320 ranges from 120 degrees to 150 degrees. In one embodiment, the included angle between the two inclined slopes 320 is 120 degrees.

[0042] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
