Description

Technical Field

[0001] This utility model relates to the field of thyristor switching technology, and in particular to a heat dissipation structure for thyristor switches. Background Technology

[0002] As a key component in the field of power electronics, thyristors are widely used in numerous fields, including industrial motor speed control, reactive power compensation in power systems, grid connection of new energy power generation, and control of household appliances, thanks to their efficient and controllable rectification, inversion, and voltage regulation functions. In modern industrial automated production lines, thyristor switches play a crucial role in precisely controlling current and stabilizing power supply; and in new energy projects such as wind power and photovoltaic power generation, they are indispensable core components for power conversion.

[0003] Currently, the most common thyristor cooling structures on the market mainly adopt air cooling or liquid cooling. Air cooling uses an axial fan to force convection, accelerating the flow of air between the heat sink fins, thereby quickly removing the heat generated by the thyristor. When the axial fan is running at high speed, it creates negative pressure to draw in outside air. The airflow carrying impurities directly enters the heat dissipation channel. Small dust particles can easily pass through the gaps between the heat sink fins and adhere to the circuit board, terminals, and electronic components of the thyristor switch. As the operating time increases, dust accumulates continuously. In a humid environment, the electrolyte components in the dust combine with moisture to form conductive dirt, causing a sharp decline in the insulation performance between adjacent lines, eventually leading to a short circuit fault. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. To overcome the aforementioned deficiencies of existing technologies, this utility model provides a thyristor switch heat dissipation structure, aiming to solve the problems mentioned in the background.

[0006] Also includes:

[0007] A limiting component, which is used to limit the position of the thyristor switch body in the mounting base;

[0008] A disassembly assembly for disassembling the filter plate within the rectangular frame.

[0009] Preferably, the limiting assembly includes a support plate, a first spring, a limiting rod, a fixing plate, and a limiting hole.

Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] Please see Figures 1 to 5 This utility model provides a heat dissipation structure for a thyristor switch, including: a mounting base 1, with slide rails at both the upper and lower ends of the mounting base 1 that cooperate with the thyristor switch body 2, providing precise guidance and stable support for the installation and disassembly of the thyristor switch body 2.

[0029] The mounting base 1 houses a thyristor switch body 2, on which heat dissipation fins 6 are mounted. These fins are arc-shaped, and their continuously curved surface effectively increases the heat dissipation area, increasing it by 20%–30% within the same volume. Simultaneously, the arc-shaped structure guides airflow to create a vortex effect, extending the residence time of air between the fins and enhancing the convective heat transfer coefficient during heat exchange.

[0030] A rectangular plate 4 is fixedly connected to the rear side wall of the thyristor switch body 2. A filter plate 5 is installed on the rectangular plate 4. A miniature fan 3 is installed on the thyristor switch body 2.

[0031] A thyristor switch heat dissipation structure further includes a limiting component and a disassembly component. The limiting component is used to limit the position of the thyristor switch body 2 on the mounting base 1. The limiting component includes a support plate 21, a first spring 22, a limiting rod 23, a fixing plate 24, and a limiting hole 25. The support plate 21 is fixedly connected to the side wall of the thyristor switch body 2. The first spring 22 is fixedly connected to the top surface of the support plate 21. The limiting rod 23 slides through the support plate 21. The fixing plate 24 is fixedly connected to the side wall of the mounting base 1. The limiting hole 25 is evenly opened on the fixing plate 24. The first spring 22 is fixedly connected to the limiting rod 23. The limiting rod 23 is inserted into the limiting hole 25.

[0032] The disassembly assembly is used to disassemble the filter plate 5 within the rectangular frame. The assembly includes a fixing block 41, a sleeve rod 42, a sliding rod 43, a second spring 44, a horizontal plate 45, and an insertion rod 46. The fixing block 41 is symmetrically fixed to the side wall of the rectangular plate 4. The sleeve rod 42 is fixedly connected to the top surface of the fixing block 41. The sliding rod 43 is slidably connected to the inner wall of the sleeve rod 42. The second spring 44 is fixedly connected to the inner wall of the sleeve rod 42. The horizontal plate 45 is fixedly connected to the end of the sliding rod 43 away from the sleeve rod 42. The insertion rod 46 is fixedly connected to the bottom end of the horizontal plate 45. The second spring 44 is fixedly connected to the sliding rod 43. The filter plate 5 has insertion holes that match the insertion rod 46, ensuring the stability of the filter plate 5 after installation and preventing it from shaking or shifting under the airflow impact of the micro fan 3, while also ensuring ease of disassembly.

[0033] In this embodiment:

[0034] First, the mounting base 1 is fixed in the required position through the threaded holes around the mounting base 1. When the thyristor switch body 2 is working, it will generate a lot of heat. The heat sink fins 6 will absorb the heat generated by the thyristor switch body 2. At the same time, the micro fan 3 will continuously flush the surface of the heat sink fins 6 with air. Through forced convection, the heat on the fins will be quickly carried away and diffused into the surrounding environment. The filter plate 5 will filter the dust and impurities in the air.

[0035] When the filter plate 5 needs to be cleaned or replaced, pull the horizontal plate 45 upward. The horizontal plate 45 drives the slide rod 43 to slide inside the sleeve rod 42, causing the second spring 44 to stretch and deform, thereby causing the insertion rod 46 to disengage from the insertion hole on the filter plate 5. At this time, the filter plate 5 can be removed from the rectangular plate 4. After cleaning or replacement, reverse the operation and reinstall the filter plate 5. The insertion rod 46 is inserted into the insertion hole of the filter plate 5 under the elastic force of the second spring 44, thus fixing the filter plate 5.

[0036] When the thyristor switch body 2 needs to be repaired, the limit rod 23 is pulled up to compress and deform the first spring 22. At this time, the thyristor switch body 2 can be moved to a suitable position on the mounting base 1. Then, the limit rod 23 is released. Under the elastic force of the first spring 22, the limit rod 23 is inserted into the limit hole 25 on the fixing plate 24, thereby limiting and fixing the thyristor switch body 2 to prevent the thyristor switch body 2 from sliding during repair, which would affect the repair effect.

[0037] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
