Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically to an I-shaped busbar with a modular and detachable heat dissipation structure. Background Technology

[0002] Busbar trunking, as a key piece of equipment for power transmission and distribution, is widely used in industrial plants, data centers, commercial buildings, and rail transportation. With increasing power loads and higher integration of electrical equipment, the heat dissipation problem of busbar trunking is becoming increasingly prominent. Traditional busbar trunking relies mainly on natural convection and simple heat sink structures for heat dissipation. However, in high current density or enclosed spaces, the heat dissipation efficiency is insufficient, easily leading to excessive temperature rise, affecting conductivity, and even causing safety hazards such as insulation aging and short circuits. Many existing busbar trunking structures use welding or bolt fixing for heat dissipation, requiring specialized tools and sometimes even requiring shutdown for work, affecting power supply continuity and increasing maintenance costs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an I-shaped busbar trunking with a modular and detachable heat dissipation structure to solve the problems mentioned in the background section.

[0004] Many existing busbar cooling structures are fixed by welding or bolts. Disassembling and replacing the cooling components requires specialized tools and may even require shutdown, affecting power supply continuity and increasing maintenance costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A modular, detachable heat dissipation structure for an I-shaped busbar trunking includes a busbar trunking body. Connecting frames are fixedly connected to both sides of the busbar trunking body. A heat dissipation component is detachably connected inside the connecting frames. Connecting slots are formed on both sides of the busbar trunking body. A sliding rod is symmetrically fixedly connected to one side of the heat dissipation component. A handle is slidably connected to the outer side of the sliding rod. A connecting post is fixedly connected to one side of the heat dissipation component. A sleeve rod is fixedly connected inside the handle. The outer side of the connecting post is slidably connected to the sleeve rod. A fixing frame is fixedly connected to one side of the connecting post. A moving block is slidably connected inside the fixing frame. An adjusting rod is rotatably connected to one side of the sleeve rod. A moving plate is rotatably connected to the end of the adjusting rod away from the sleeve rod. The bottom of the moving plate is fixedly connected to the moving block. Locking blocks are slidably connected inside both sides of the busbar trunking body.

[0007] Preferably, the heat dissipation assembly includes a heat-conducting plate, heat dissipation fins, a mounting box, an air vent, and an exhaust fan. The heat-conducting plate is detachably connected to both sides of the main body of the busbar trunking. The mounting box is fixedly connected to one end of the heat-conducting plate. Multiple heat dissipation fins are fixedly connected to one side of the heat-conducting plate. An exhaust fan is installed inside the mounting box. An air vent is provided on the side of the mounting box near the heat dissipation fins.

[0008] Preferably, a connecting plate is fixedly connected to one side of the card block, and the outer side of the connecting plate is slidably connected to the main body of the busbar.

[0009] Preferably, a pressure spring is fixedly connected between one side of the connecting plate and the main body of the busbar.

[0010] Preferably, a filter plate is fixedly connected to the top of the busbar trunking body.

[0011] Preferably, a tension spring is fixedly connected between one side of the grip and the connecting post.

[0012] This invention provides an I-shaped busbar trunking with a modular, detachable heat dissipation structure. Compared with the prior art, it has the following advantages:

[0013] 1. This modular, detachable heat dissipation structure for the I-shaped busbar trunking achieves quick assembly and disassembly with self-locking by setting up the busbar trunking body, heat dissipation components, connecting frame, locking block, handle, slide rod, connecting plate, pressure spring, connecting column, sleeve rod, tension spring, adjusting rod, moving plate, fixed frame, and moving block.

[0014] 2. The modular and detachable heat dissipation structure of the I-shaped busbar trunking achieves heat dissipation by setting up the busbar trunking body, filter plate, heat dissipation components, connecting frame and connecting slot. The exhaust fan draws hot air from inside the busbar trunking through the connecting slot, forming a negative pressure that forces external cold air to enter through the top filter plate, forming a closed-loop air duct. The heat dissipation fins and heat conduction plate work together to transfer the heat inside the busbar trunking body to the outside air, further improving the heat dissipation effect on the busbar trunking body.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-8This utility model provides a technical solution: a modular, detachable heat dissipation structure for an I-shaped busbar trunking, including a busbar trunking body 1. Connecting frames 4 are fixedly connected to both sides of the busbar trunking body 1. Heat dissipation components 3 are detachably connected inside the connecting frames 4, better fixing the heat dissipation components 3 to both sides of the busbar trunking body 1. Two sets of heat dissipation components 3 are provided, and the two sets of heat dissipation components 3 are centrally symmetrical. Connecting slots 5 are opened on both sides of the busbar trunking body 1, and the two sets of connecting slots 5 are centrally symmetrical. A sliding rod 8 is symmetrically fixedly connected to one side of the heat dissipation components 3. A handle 7 is slidably connected to the outside of the sliding rod 8, and the handle 7 moves along the outside of the sliding rod 8. A connecting post 12 is fixedly connected to one side of the heat dissipation components 3. A sleeve rod 13 is fixedly connected inside the handle 7. The movement of the connecting post 12 moves the sleeve rod 13. The outer side of 2 is slidably connected to the sleeve rod 13. The sleeve rod 13 moves along the outer side of the connecting column 12. A fixed frame 17 is fixedly connected to one side of the connecting column 12. A moving block 18 is slidably connected inside the fixed frame 17. The moving block 18 moves along the inside of the fixed frame 17. An adjusting rod 15 is rotatably connected to one side of the sleeve rod 13. The movement of the sleeve rod 13 moves the adjusting rod 15. A moving plate 16 is rotatably connected to the end of the adjusting rod 15 away from the sleeve rod 13. The movement of the adjusting rod 15 moves the moving plate 16. The bottom of the moving plate 16 is fixedly connected to the moving block 18. The movement of the moving plate 16 moves the moving block 18. A locking block 6 is slidably connected inside both sides of the busbar trunking body 1. The movement of the moving block 18 presses against the locking block 6, and the locking block 6 restricts the heat dissipation component 3 within the connecting frame 4.

[0026] Furthermore, the heat dissipation component 3 includes a heat-conducting plate 301, heat dissipation fins 302, a mounting box 303, an air vent 304, and an exhaust fan 305. The heat-conducting plate 301 is detachably connected to both sides of the busbar trunking body 1. The heat-conducting plate 301 conducts the heat generated by the busbar trunking body 1. The mounting box 303 is fixedly connected to one end of the heat-conducting plate 301. Multiple heat dissipation fins 302 are fixedly connected to one side of the heat-conducting plate 301 to increase the heat dissipation area and improve the heat dissipation efficiency. An exhaust fan 305 is installed inside the mounting box 303. When the exhaust fan 305 is turned on, it extracts the gas inside the busbar trunking body 1 through the connecting groove 5, further improving the heat dissipation of the busbar trunking body 1. An air vent 304 is opened on the side of the mounting box 303 near the heat dissipation fins 302. The gas extracted by the exhaust fan 305 is discharged through the air vent 304, improving the airflow between the heat dissipation fins 302.

[0027] Furthermore, a connecting plate 10 is fixedly connected to one side of the card block 6. The moving connecting plate 10 moves the card block 6. The outer side of the connecting plate 10 is slidably connected to the busbar trunking body 1 to prevent the card block 6 from leaving the busbar trunking body 1.

[0028] Furthermore, a pressure spring 11 is fixedly connected between one side of the connecting plate 10 and the main body 1 of the busbar trunking. When the locking block 6 is squeezed, it moves towards the pressure spring 11. The pressure spring 11 generates elastic force under pressure. When the heat dissipation component 3 is fully inserted into the connecting frame 4, the pressure spring 11 loses its pressing force. Under the action of the elastic force, the pressure spring 11 returns to its original position through the connecting plate 10 with the locking block 6. The locking block 6 moves to one end of the heat dissipation component 3 and fixes the heat dissipation component 3 in the connecting frame 4.

[0029] Furthermore, a filter plate 2 is fixedly connected to the top of the busbar trunking body 1 to filter the gas entering the busbar trunking body 1.

[0030] Furthermore, a tension spring 14 is fixedly connected between one side of the handle 7 and the connecting post 12. The handle 7 moves along the outside of the connecting post 12 to stretch the tension spring 14. When the tension on the tension spring 14 disappears, the tension spring 14 returns to its original position with the handle 7 under the action of the elastic force.

[0031] In use, the heat dissipation component 3 is inserted into the connecting frame 4 along one side of the busbar trunking body 1. When the heat dissipation component 3 moves, it presses against the locking block 6. The locking block 6 moves towards the pressure spring 11 under pressure, generating elastic force. When the heat dissipation component 3 is fully inserted into the connecting frame 4, the pressure spring 11 loses its pressing force. Under the action of the elastic force, the pressure spring 11, through the connecting plate 10, moves the locking block 6 back to its original position. The locking block 6 moves to one end of the heat dissipation component 3, fixing the heat dissipation component 3 in the connecting frame 4. The heat generated by the busbar trunking body 1 during operation is transferred to the heat dissipation fins 302 through the heat conduction plate 301. The heat dissipation fins 302 transfer the heat inside the busbar trunking body 1 to the outside air. The exhaust fan 305 is turned on, and the exhaust fan 305 extracts the gas from the busbar trunking body 1, allowing the cooler outside gas to enter the busbar trunking after being filtered by the filter plate 2. Inside the main body 1, the gas drawn out by the exhaust fan 305 blows out through the air outlet 304 onto the heat dissipation fins 302, enhancing the airflow between the heat dissipation fins 302 and improving the heat dissipation efficiency of the heat dissipation fins 302. When the heat dissipation component 3 needs to be disassembled, the handle 7 is pulled. At the beginning of the movement of the handle 7, the locking block 6 is still located on one side of the heat dissipation component 3, so the heat dissipation component 3 will not move. The handle 7 moves along the outside of the connecting post 12 with the sleeve rod 13. The tension spring 14 is stretched and unfolded. The sleeve rod 13 moves with the moving plate 16 through the adjusting rod 15. The moving plate 16 moves with the moving block 18 within the fixed frame 17. During the movement of the moving block 18, it squeezes the locking block 6 until the locking block 6 is removed from one side of the heat dissipation component 3, so that the heat dissipation component 3 leaves the connecting frame 4. Under the action of the tension spring 14, the handle 7 will return to its original position with the moving block 18.
