Description

Technical Field

[0001] This invention relates to the field of reactor heat dissipation, specifically to an active heat dissipation system for reactors. Background Technology

[0002] Reactors, as important electrical equipment, are widely used in reactive power compensation, filtering, and current limiting in power systems. During operation, they generate a large amount of heat due to the resistive losses of their internal coils and the hysteresis and eddy current losses of their iron core. Effective heat dissipation is a crucial aspect of electrical equipment design and maintenance to ensure the safe, stable, and efficient operation of reactors and extend their service life.

[0003] However, existing forced air cooling methods using fixed fans have a fixed airflow direction and limited coverage area. The fixed airflow makes it difficult to cool the entire device evenly, and heat tends to accumulate in local areas, resulting in uneven heat dissipation. Long-term operation may affect the performance and reliability of the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide an active heat dissipation system for reactors to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0014] Furthermore, the dustproof mechanism includes an outer shell fixedly connected to the upper ends of both sides of the electrical box, a dustproof net fixedly connected to the inner side of the bottom end of the outer shell, and an air inlet that passes through and is connected to the outer shell on the upper sides of both sides of the electrical box. The side of the outer shell away from the electrical box is inclined towards each other, and the side of the dustproof net away from the electrical box is inclined upward and fixedly connected to the inner wall of the outer shell.

[0015] Furthermore, both sides of the upper inner wall of the electrical box are fixedly connected to guide tubes that are on the same horizontal line as the dovetail slide.

[0016] Furthermore, exhaust vents are provided on both sides of the bottom of the electrical box, and baffles are fixedly connected to the exhaust vents.

[0017] Furthermore, a controller and a temperature sensor are fixedly connected to the upper front side of the electrical box, and the temperature sensor is electrically connected to motor one and motor two through the controller.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1-5 As shown, the present invention provides a technical solution:

[0030] An active cooling system for a reactor includes an electrical box 1, to which the reactor body 2 is detachably connected by bolts to its inner bottom wall; a transmission box 3, which is fixedly connected to the top center of the electrical box 1; a swing mechanism is provided between the transmission box 3 and the electrical box 1; the swing mechanism includes a column 4 fixedly connected to the inner top wall of the transmission box 3, and a through hole 5 extending through the top center of the electrical box 1; the bottom end of the column 4 passes downward through the through hole 5 and is fixedly connected to a transverse guide rail 6; a dovetail groove 7 is transversely provided on the front side of the guide rail 6, and a dovetail slider 8 is slidably fitted in the dovetail groove 7; the swing mechanism also includes a fixing rod 9 fixedly connected to the middle of the front side of the dovetail slider 8. A motor 10 is fixedly connected to the middle of the front side of the transmission box 3; a rotating disk 11 is rotatably connected to the middle of the rear side of the column 4 via bearings; and a drive rod 12 is fixedly connected to the eccentric side of the rear side of the rotating disk 11. The output shaft of the motor 10 is fixedly connected to the rotation center shaft of the rotating disk 11. A swing frame 13 is hinged to the upper rear side of the column 4. The two ends of the swing frame 13 are respectively provided with an elongated hole 14 and an elongated hole 15. The elongated hole 14 is slidably engaged with the drive rod 12, and the elongated hole 15 is slidably engaged with the fixed rod 9. A heat dissipation mechanism is set inside the upper part of the electrical box 1 and is used in conjunction with the swing mechanism. The heat dissipation mechanism includes a drive rod 12 fixedly connected to the swing frame 10. The frame 13 has a horizontal plate 16 at the rear bottom, a fan blade 17 located below the horizontal plate 16, and a second motor 18 fixedly connected to the middle of the top of the horizontal plate 16. The output shaft of the second motor 18 is fixedly connected to the fan blade 17 to drive its rotation. A controller 27 and a temperature sensor 28 are fixedly connected to the upper front of the electrical box 1. The temperature sensor 28 is electrically connected to the first motor 10 and the second motor 18 through the controller 27. A dustproof mechanism is located on the upper exterior of both sides of the electrical box 1 and works in conjunction with the swing mechanism. The dustproof mechanism includes a housing 19 fixedly connected to the upper sides of both sides of the electrical box 1 and a dustproof net 20 fixedly connected to the inner bottom of the housing 19. The electrical box 1 has air inlets 21 that are opened on both sides above and connected to the outer casing 19. The outer casing 19 is tilted away from the electrical box 1. The dustproof net 20 is tilted upward away from the electrical box 1 and fixedly connected to the inner wall of the outer casing 19. The upper inner wall of the electrical box 1 is fixedly connected to the conduits 22 on both sides, which are at the same level as the dovetail slide 7. Movable holes 23 are opened on the side wall of the electrical box 1 at the position corresponding to the conduits 22. The dovetail slider 8 is fixedly connected to the two ends of the dovetail slider 8. The dovetail slider 24 slides with the conduits 22. The bottom end of the electrical box 1 is provided with exhaust ports 25 on both sides. A baffle 26 is fixedly connected in the exhaust port 25.

[0031] In this embodiment, the periodic reciprocating oscillation of the fan blade 17 is achieved through the combined use of the swing frame 13, the motor 10, and the rotating disk 11, which can uniformly dissipate heat from the reactor body 2 and avoid local overheating.

[0032] By using the dovetail slider 8, the impact rod 24 and the outer shell 19 together, the outer shell 19 is reciprocated and impacted simultaneously during the heat dissipation swing process, which can automatically clean the dust accumulated on the surface of the dust filter 20 and maintain smooth air intake.

[0033] Both the outer casing 19 and the dustproof net 20 are inclined structures, and in conjunction with the impact action of the impact bar 24, they effectively prevent rainwater from entering the electrical box 1 outdoors, and allow the shaken dust to automatically slide down the inclined surface under the action of gravity, avoiding secondary accumulation.

[0034] Working principle: After startup, temperature sensor 28 monitors the internal temperature of electrical box 1 and transmits the signal to controller 27. When the temperature reaches the set threshold, controller 27 controls motor 2 18 to start, driving fan blade 17 to rotate. The rotation of fan blade 17 drives external air to pass through dust filter 20 and enter the electrical box 1 through air inlet 21, forming airflow to cool the reactor body 2 below. At the same time, controller 27 controls motor 10 to start, driving rotating disk 11 to rotate around its rotation center axis. Drive rod 12, fixed at the eccentric position of rotating disk 11, performs circular motion accordingly. Drive rod 12 slides in the elongated hole 14 at one end of swing frame 13 and drives swing frame 13 to reciprocate around its hinge point with column 4. The horizontal plate 16, motor 2 18, and fan blades are fixed to the rear side of the bottom of swing frame 13. As a whole, the fan blade 17 reciprocates synchronously with the swing frame 13, allowing the airflow generated by the fan blade 17 to periodically sweep across different areas above the reactor body 2, achieving uniform heat dissipation through reciprocating oscillation, improving heat dissipation efficiency and avoiding local overheating. During the reciprocating oscillation of the swing frame 13, the fixed rod 9 is driven to slide horizontally along the dovetail groove 7 on the guide rail 6 through the sliding cooperation between the elongated hole 15 and the fixed rod 9. The striking rods 24 at both ends of the dovetail slider 8 slide with it and extend into the corresponding guide tubes 22 through the movable holes 23. With the reciprocating movement of the dovetail slider 8, the striking rods 24 on both sides reciprocate to strike the outer shell 19 on both sides of the electrical box 1. When the shell 19 is struck, it vibrates, thereby shaking off the dust adhering to the outer surface of the dustproof net 20 inside, keeping the air inlet 21 unobstructed. After the airflow passes through the reactor body 2 for heat exchange, it is finally discharged from the exhaust port 25 at the bottom of the electrical box 1, and the baffle 26 prevents foreign objects from entering from the exhaust port 25.
