Abstract
Description
Technical Field
[0001] This utility model relates to the field of inverter technology, and more specifically, to a high-efficiency cooling and heat dissipation module for wind power plant inverters. Background Technology
[0002] A wind power inverter is a device that converts the alternating current (AC) generated by a wind turbine into standard AC power suitable for the power grid or load. Because the output frequency and voltage of wind turbines are unstable, the inverter plays a crucial role in wind power generation systems. Inverters generate a significant amount of heat during operation; to prevent damage to internal components due to insufficient heat dissipation, a cooling system is necessary.
[0003] Existing inverter cooling structures mainly rely on fans installed inside the inverter for heat dissipation. The fans accelerate airflow to achieve a cooling effect. However, when the heat inside the inverter is high, a single fan is insufficient for rapid heat dissipation. Furthermore, when the inverter is installed outdoors, insects can easily enter the inverter through the air intake. The dead insects may block the heat dissipation channels, affecting heat dissipation, and may also cause short circuits, leading to equipment failure or damage and affecting the normal operation of the inverter.
[0004] In view of this, we propose a high-efficiency cooling and heat dissipation module for wind farm inverters. Utility Model Content

Two sets of mounting blocks are fixedly mounted inside the fixed frame, and cleaning brushes are fixedly mounted on the outer sides of both sets of mounting blocks.

[0027] Please see Figure 1-5 This utility model provides a technical solution:
[0028] A high-efficiency cooling and heat dissipation module for a wind power inverter includes an inverter body 1, a fixed frame 2 on the outer side of the inverter body 1, an inner fan 3 on the inner side of the fixed frame 2, and multiple sets of heat dissipation fins 4 fixedly mounted on both sides of the inverter body 1. External fans 5, which connect to the heat dissipation fins 4, are fixedly mounted on both sides of the fixed frame 2. A mounting plate 7 is mounted on the upper side of the fixed frame 2, and two sets of mounting frames 8 are fixedly mounted on the lower side of the mounting plate 7. Both sets of mounting frames 8 are movably inserted into the fixed frame 2 and extend inward. An electric mosquito net 9 is mounted inside one set of mounting frames 8 to support the electric mosquito net 9. A battery and a high-voltage generator are also mounted inside the mounting frames 8, with the battery energizing the high-voltage generator. The high-voltage generator converts low voltage to high voltage to power the electric mosquito net 9. The battery only needs to be charged periodically. A filter screen 10 is installed inside the other set of mounting frames 8, and two sets of mounting blocks 11 are fixedly installed inside the fixed frame 2. Cleaning brushes 12 are fixedly installed on the outside of both sets of mounting blocks 11. During use, the mounting plate 7 can be pulled upward to move the electric mosquito net 9 and the filter screen 10. The cleaning brushes 12 can be used to clean the electric mosquito net 9 and the filter screen 10, improving the convenience of cleaning. When needed, the electric mosquito net 9 and the filter screen 10 can also be pulled out from inside the fixed frame 2. In addition, the cleaning brushes 12 are soft brushes to avoid damage to the electric mosquito net 9 and the filter screen 10 by hard brushes.
[0029] Specifically, multiple air inlets 6 are provided on the outer side of the fixed frame 2. The air inlets 6 facilitate the entry of external air into the fixed frame 2 and the inverter body 1. At the same time, an exhaust port is provided on the other side of the inverter body 1 to facilitate the exhaust of air, thereby achieving the purpose of ventilation and heat dissipation.
[0030] Furthermore, a collection box 13 is provided on the lower side of the fixed frame 2. The collection box 13 can collect the cleaned dust and mosquito corpses, which facilitates subsequent unified cleaning.
[0031] It is worth noting that two sets of L-shaped blocks 14 are fixedly installed on the upper side of the collection frame 13, and two sets of L-shaped grooves 15 are opened on the outer side of the fixed frame 2 to engage the L-shaped blocks 14. When the L-shaped blocks 14 are inserted into the inner side of the L-shaped grooves 15, the L-shaped grooves 15 limit the L-shaped blocks 14, which can facilitate the installation and limit of the collection frame 13, improve the installation convenience of the collection frame 13, and facilitate the subsequent disassembly of the collection frame 13, thereby facilitating the cleaning of dust and insect corpses and improving the ease of use.
[0032] It is worth noting that two sets of magnets 16 are fixedly installed on the upper side of the fixed frame 2. The mounting plate 7 is made of metal material. Through the magnetic attraction effect of the magnets 16 on the mounting plate 7, the mounting plate 7 can be quickly installed and positioned, improving the ease of installation of the mounting plate 7. At the same time, it is also convenient to move the mounting plate 7 in the future.
[0033] In addition, a handle is fixedly installed on the outside of the mounting plate 7, and an insulating sleeve is fixedly fitted on the outside of the handle. The handle allows the mounting plate 7 to be pulled upwards easily, improving the ease of operation. At the same time, the insulating sleeve can improve the insulation effect of the handle and ensure the safety of operation.
[0034] Working principle: First, when the inverter body 1 is in use, the internal fan 3 directly dissipates heat from the inside of the inverter body 1. At the same time, the heat dissipation fins 4 can conduct heat out of the inside of the inverter body 1. The external fan 5 dissipates heat from the heat dissipation fins 4 to ensure the heat dissipation effect. When mosquitoes or dust enter the fixed frame 2 through the air inlet 6, the mosquitoes will be electrocuted by the electric mosquito net 9 and the mosquito corpses will fall into the collection frame 13. At the same time, the filter screen 10 can filter the dust. When mosquito corpses and dust adhere to the electric mosquito net 9 and the filter screen 10, the mounting plate 7 is pulled upward to move the mounting frame 8. The movement of the mounting frame 8 moves the electric mosquito net 9 and the filter screen 10 upward. At this time, the two sets of cleaning brushes 12 can clean the mosquito corpses and dust on the electric mosquito net 9 and the filter screen 10. The collection frame 13 can collect the mosquito corpses and dust.
