Description

Technical Field

[0001] This invention relates to the field of dense busbar trunking, and more specifically, to dense busbar trunking based on graphene heat dissipation components and its assembly method. Background Technology

[0002] Compact busbar trunking is a high-efficiency power transmission device, mainly composed of a metal casing, conductive bars, and insulation materials. It features a compact structure, small footprint, high current transmission capacity, and easy installation, and is widely used in industrial plants, commercial buildings, high-rise buildings, and other similar locations.

[0003] When high-density busbar trunking is in operation, the large current flowing through the conductors generates a significant amount of heat (due to the greater number of conductors compared to a standard busbar trunking system). If this heat cannot be dissipated promptly, the internal temperature of the busbar trunking will rise, affecting the performance of the insulation material, reducing its insulation strength, and potentially causing electrical faults. Furthermore, high temperatures increase the resistance of the conductors, reducing the current-carrying capacity of the busbar trunking and impacting the normal operation of the power system. Simultaneously, excessively high temperatures can also affect the metal casing of the busbar trunking, causing deformation, discoloration, and even potentially leading to fires and other safety hazards.

[0004] Traditional heat dissipation methods for compact busbar trunking primarily rely on natural cooling. Natural cooling depends on the busbar trunking itself radiating and conducting heat to the surrounding environment, offering low cost and reliable operation, but with relatively low heat dissipation efficiency. However, under high current load conditions, the heat dissipation of compact busbar trunking increases significantly. Traditional cooling methods struggle to dissipate this large amount of heat quickly, potentially causing the busbar trunking temperature to exceed its allowable operating temperature range, affecting insulation performance and lifespan, and increasing conductor resistance, creating a vicious cycle. Furthermore, in confined installation spaces, the required heat dissipation area and airflow space for natural cooling are limited, hindering natural air convection and reducing heat dissipation efficiency. The limited space also makes it unsuitable for installing air-cooled devices (which are bulky), significantly increasing the probability of damage to the compact busbar trunking. Moreover, traditional ventilation structures (natural cooling) typically use dust filters at the vents, often secured with screws and clips. These filters are difficult to completely seal, leaving large gaps and resulting in poor dust protection.

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes a dense busbar trunking based on graphene heat dissipation components and its assembly method. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a dense busbar trunking based on graphene heat dissipation components and its assembly method.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a dense busbar trunking based on graphene heat dissipation components, comprising a busbar trunking body and cover plates disposed on the upper and lower surfaces of the busbar trunking body; the dense busbar trunking based on graphene heat dissipation components further includes:

[0008] The graphene heat dissipation component is embedded and fixed inside the cover plate, and has a telescopic structure to bring its connecting surface into contact with the surface of the bus conductor, thereby conducting the heat of the bus conductor to the outside.

[0009] The connecting and fixing components are used to install the cover plate on the busbar trunking body and fix the connecting surface of the graphene heat dissipation component in contact with the surface of the busbar conductor.

[0010] The ventilation structure is located on the side of the busbar trunking body. The dustproof net is installed on the busbar trunking body through a concave-convex fit to reduce installation gaps.

[0011] Preferably, the graphene heat dissipation component includes a graphene heat sink embedded and fixed on the cover plate, with its top being an irregular groove shape and its bottom being a flat shape; the bottom of the graphene heat sink is connected to a heat-conducting plate through a telescopic structure, and a thermally conductive silicone pad is adhered to the bottom end of the heat-conducting plate.

[0012] Preferably, the telescopic structure includes a thermally conductive telescopic rod fixed between the graphene heat sink and the heat-conducting plate.

[0013] Preferably, the connection and fixing assembly includes fixing screws A fixed on the upper and lower sides of the busbar trunking body, and pressing screws threaded to both sides of the cover plate. The cover plate has through holes A for the fixing screws A to pass through. The fixing screws A press down on the heat-conducting plate to promote the heat-conducting silicone pad to adhere tightly to the surface of the busbar conductor. The advantage of this structure is that there are almost no protruding structures that obstruct the installation of the busbar trunking body, and it can better cope with various narrow spaces.

[0014] Preferably, the head of the pressing screw is fixedly connected to a handle that facilitates its rotation, and an arc-shaped plate is fixedly connected to the surface of the cover plate on the side of the pressing screw. The arc-shaped plate is internally threaded with screws. The handle allows the operator to rotate the pressing screw and the screws can be used to tighten the pressing screw.

[0015] Preferably, the connection and fixing assembly includes a groove seat fixed to the upper and lower surfaces of the busbar trunking body, and a through-slot seat. The bottom ends of the cover plate are fixedly connected to protrusions that can be inserted into the groove seats. An elastic component is also installed in a localized area between the protrusions on both sides of the bottom end of the cover plate, and the telescopic end of the elastic component is fixed to the top surface of the heat-conducting plate. After the protrusions are fully inserted into the groove seats, the elastic component is in a compressed state, promoting the thermally conductive silicone pad to adhere tightly to the surface of the busbar conductor through elasticity. A sliding rod is fixedly connected inside the through-slot seat. Sliding sleeves are slidably connected to the outer side walls of the sliding rods. The surface of the sliding sleeves is fixed to the side end of the cover plate via connecting plate A. Horizontal plates are fixedly connected to the upper and lower sides of the back of the through slot seat, and connecting screws are fixedly connected between the horizontal plates. Through plates are fixedly connected to the back of the sliding sleeves. Through holes B are opened inside the through plates for the connecting screws to pass through. Two cover plates can be installed simultaneously in one operation. When installing the cover plates, the thermally conductive silicone pads and the thermally conductive surface of the busbar can be pressed tightly together without extra operations, making the assembly operation more convenient.

[0016] Preferably, the elastic component includes a lower-opening circular groove fixed to the bottom surface of the cover plate. Multiple springs are arranged in a circumferential array on the inner top wall of the lower-opening circular groove, and the head of each spring is fixedly connected to a circular plate. A guide rail A for sliding slider A is fixedly connected to the inner surface of the lower-opening circular groove. The surface of slider A is fixed to the side end of the circular plate, and the bottom of the circular plate is fixed to the top of the heat-conducting plate by a vertical rod.

[0017] Preferably, the ventilation structure includes an opening slot on one side of the busbar trunking body, a frame plate A welded around the opening slot on the surface of the busbar trunking body, a frame slot inside the frame plate A, a frame plate B inserted inside the frame slot, a heat dissipation plate fixedly connected to the head of the frame plate B, a dustproof mesh embedded inside the heat dissipation plate, and a quick-release assembly installed between the frame plate A and the frame plate B to achieve quick assembly and disassembly.

[0018] Preferably, the quick-release assembly includes guide rails B fixed to the upper and lower sides of the frame plate A. Slider B is slidably connected to the surface of each guide rail B. A movable plate is fixedly connected to the surface of each slider B via a connecting plate B. A fixing block is fixedly connected to the back of the movable plate. Fixing grooves for inserting the fixing blocks are provided on both sides of the frame plate A. The fixing grooves extend through the frame groove and are also provided on both sides of the frame plate B. Fixing screws B are fixedly connected to the upper and lower sides of the fixing grooves on the side ends of the frame plate A. Through holes C for the fixing screws B to pass through are provided on the surface of the movable plate on the upper and lower sides of the fixing blocks. This design allows for convenient operation without requiring alignment of the fixing blocks.

[0019] The assembly method for the dense busbar trunking based on the above-mentioned graphene heat dissipation components includes the following steps:

[0020] Step 1: Pull the distance between the two cover plates to the maximum, then insert the N-shaped structure formed by the two cover plates and the connecting fixing components into the main body of the busbar trunking. After insertion, the protrusions on the cover plates are aligned with the grooves on the main body of the busbar trunking.

[0021] Step 2: Push the upper and lower cover plates towards the middle. The cover plates drive the sliding sleeve to slide. The sliding sleeve slides along the sliding rod to maintain the straight movement of the cover plates. The sliding sleeve drives the through plate to move. The through plate moves along the connecting screw. At the same time, the cover plates drive the two protrusions to move towards the middle, inserting the protrusions into the groove seat. After insertion, rotate the nut on the connecting screw so that the nut abuts against the top surface of the upper through plate and the bottom surface of the lower through plate, thereby fixing the protrusions in the groove seat.

[0022] Step 3: During the process of inserting the protrusion into the groove seat, the thermally conductive silicone pad under the heat-conducting plate will first contact the bus conductor in the main body of the busbar trunking. This will cause the heat-conducting plate to apply a force to the vertical rod in the direction of the downward-opening circular groove seat, thereby driving the circular plate to move inside the downward-opening circular groove seat. The circular plate will drive the slider A to move. The slider A will slide along the guide rail A to maintain the linear movement of the circular plate, thereby compressing the spring. The spring will use its elasticity to form a rebound force, allowing the thermally conductive silicone pad to adhere tightly to the surface of the busbar conductor for heat dissipation.

[0023] Step 4: Insert frame plate B into the frame groove. After insertion, the dustproof net should be aligned with the opening groove.

[0024] Step 5: Move the movable plate towards frame plate A. The movable plate moves the fixed block and also moves the slider B. The slider B slides along the guide rail B to maintain the linear movement of the fixed block. The fixed block can then be inserted into the fixing slot of frame plate A. During the insertion process, it also passes through the fixing through slot on frame plate B, thus confining the frame plate within the frame slot. At this time, the fixing screw B on frame plate A also passes through the through hole C on the movable plate. By rotating the nut clockwise, the nut is installed on the fixing screw B, thereby fixing the movable plate to frame plate A. This completes the operation of fixing frame plate B within the frame slot, and finally completes the assembly of the compact busbar trunking.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The additional heat dissipation structure of the present invention can assist the traditional ventilation structure in heat dissipation, enhance the heat dissipation effect of the dense busbar trunking, and the assembly method of the present invention is simple and feasible. Most of the additional structures are set inside the dense busbar trunking, which does not occupy installation space and can be applied to various narrow spaces. Moreover, the filter screen on the ventilation structure is installed in a concave-convex fit to reduce installation gaps and improve dust prevention effect, thereby solving the problems of poor heat dissipation effect of existing dense busbar trunking in the background art, which makes it even more difficult to be applied to narrow spaces, and the large installation gaps of the protective screen.

[0027] 2. In this invention, the movable plate is pushed to move towards the frame plate A. The movable plate drives the fixed block to move, and at the same time, the movable plate also drives the slider B to move. The slider B slides along the guide rail B to maintain the linear movement of the fixed block. The fixed block can then be inserted into the fixed groove of the frame plate A. During the insertion process, it also passes through the fixed through groove on the frame plate B, thereby restricting the frame plate in the frame groove. At this time, the fixing screw B on the frame plate A also passes through the through hole C on the movable plate. By rotating the nut clockwise, the nut is installed on the fixing screw B, thereby fixing the movable plate to the frame plate A. This completes the operation of fixing the frame plate B in the frame groove. Conversely, by removing the nut and pulling the movable plate to move in the opposite direction to return to the initial position, the fixing of the frame plate B can be released. The disassembly and assembly operation is relatively simple and does not require the alignment operation of the fixed block.

[0028] 3. This invention provides two specific implementation methods for the connection and fixing components. The first method has almost no protruding structure that obstructs the installation of the busbar trunking body, and can better cope with various narrow spaces. The second method allows two cover plates to be installed at the same time in one operation. When installing the cover plates, the thermally conductive silicone pad can be pressed tightly against the thermally conductive surface of the busbar, without any extra operations. The assembly operation is more convenient, and the staff can choose to use it as needed. Attached Figure Description

[0043] Example 1

[0044] like Figures 1 to 9As shown, the present invention provides a dense busbar trunking based on graphene heat dissipation components, including a busbar trunking body 1 and cover plates 2 disposed on the upper and lower surfaces of the busbar trunking body 1. The dense busbar trunking based on graphene heat dissipation components 3 further includes:

[0045] The graphene heat dissipation component 3 is embedded and fixed inside the cover plate 2. It has a telescopic structure 301 to make its connection surface contact the surface of the bus conductor, thereby conducting the heat of the bus conductor to the outside. The graphene heat dissipation component 3 includes a graphene heat sink 302 embedded and fixed on the cover plate 2. Its top is set in an irregular groove shape and its bottom is flat. The bottom of the graphene heat sink 302 is connected to the heat conduction plate 303 through the telescopic structure 301. A thermally conductive silicone pad 304 is attached to the bottom end of the heat conduction plate 303.

[0046] The connecting and fixing component 4 is used to install the cover plate 2 on the busbar trunking body 1 and fix the connecting surface of the graphene heat dissipation component 3 in contact with the surface of the busbar conductor.

[0047] The ventilation structure is located on the side of the bus trunking body 1. The dustproof net 506 is installed on the bus trunking body 1 by means of a concave-convex fit to reduce the installation gap.

[0048] In use, the two cover plates 2 are installed on the graphene heat dissipation assembly 3 by connecting and fixing component 4. After installation, the thermally conductive silicone pad 304 (connecting surface) on the graphene heat dissipation assembly 3 is fixed in contact with the surface of the bus conductor by connecting and fixing component 4. The telescopic structure 301 extends to ensure that the connecting surface of the graphene heat dissipation assembly 3 is in contact with the surface of the bus conductor, so as to ensure that the heat dissipation connection of the graphene heat dissipation assembly 3 is not interrupted, thereby conducting the heat of the bus conductor to the outside (heat dissipation conduction: heat of bus conductor -- thermally conductive silicone pad 304 -- heat-conducting plate 303 -- telescopic structure 301 -- graphene heat sink 302), to assist the traditional ventilation structure in heat dissipation, enhance the heat dissipation effect of the dense bus trunking. Moreover, the assembly method of this invention is simple and feasible. Most of the additional structures are set inside the dense bus trunking (in the space between the cover plate 2 and the main body 1 of the bus trunking), which does not occupy installation space and can be applied to various narrow spaces. In addition, the filter screen on the ventilation structure (traditional) is installed in a concave-convex fit to reduce installation gaps and improve dust prevention effect.

[0049] The telescopic structure 301 is preferably a heat-conducting telescopic rod 3011. It should be noted that the heat-conducting telescopic rod 3011 and the heat-conducting plate 303 are made of aluminum alloy. Aluminum alloy has high thermal conductivity, is lightweight, and is corrosion-resistant. Furthermore, the heat-conducting silicone pad 304 is relatively soft, possessing good elasticity and deformability. Under compression, the silicone pad can deform according to the surface shape of the object, thus adhering closely to it. This softness allows the silicone pad to adapt to surfaces of different shapes and roughnesses, ensuring maximum contact area for better heat dissipation. The graphene heat sink 302 has an irregular groove shape, which increases the contact area with the outside environment, thereby significantly improving the heat dissipation effect.

[0050] Example 2

[0051] like Figure 1 , Figures 3 to 5 As shown in the figure, this embodiment provides a specific structure for the ventilation structure to be installed with a concave-convex fit:

[0052] The ventilation structure 5 includes an opening slot 501 on one side of the busbar trunking body 1. A frame plate A502 is welded around the opening slot 501 on the surface of the busbar trunking body 1. A frame slot 503 is formed inside the frame plate A502. A frame plate B504 is inserted into the frame slot 503. A heat dissipation plate 505 is fixedly connected to the head of the frame plate B504. A dustproof mesh 506 is embedded inside the heat dissipation plate 505. A quick-release assembly 507 is installed between the frame plate A502 and the frame plate B504 to achieve quick assembly and disassembly.

[0053] Ventilation is achieved for the bus conductors inside the bus trunking body 1 through the opening slot 501, enabling natural cooling. The dustproof net 506 is embedded and fixed to the heat dissipation plate 505 during manufacturing. During installation, the frame plate B504 is inserted into the frame slot 503. After insertion, the frame plate B504 is fixed in the frame slot 503 through the quick-release assembly 507. After installation, the dustproof net 506 is exactly opposite to the opening slot 501, providing dust protection while ventilating and dissipating heat, preventing dust from entering the bus trunking body 1. In this way, the concave and convex fit (the frame plate B504 and the frame slot 503 are designed to fit together tightly to reduce gaps) can seal the dustproof net around its perimeter, thereby effectively reducing installation gaps and preventing dust from entering the bus trunking body 1 through gaps.

[0054] The quick-release assembly 507 includes guide rails B5071 fixed to the upper and lower sides of the frame plate A502. Slider B5072 is slidably connected to the surface of the guide rails B5071. A movable plate 5074 is fixedly connected to the surface of the slider B5072 through a connecting plate B5073. A fixing block 5075 is fixedly connected to the back of the movable plate 5074. Fixing grooves 5076 for the fixing blocks 5075 to be inserted are opened on both sides of the frame plate A502. The fixing grooves 5076 extend through the frame groove 503 and fixing through grooves 5077 are opened on both sides of the frame plate B504. Through holes C5079 for fixing screws B5078 to pass through are opened on the surface of the movable plate 5074 on both the upper and lower sides of the fixing block 5075.

[0055] After the frame plate B504 is inserted into the frame groove 503, the fixing block 5075 on the moving plate 5074 is aligned with the fixing groove 5076 and the fixing through groove 5077. Then, the moving plate 5074 is pushed to move towards the frame plate A502. The moving plate 5074 drives the movement of the fixing block 5075. At the same time, the moving plate 5074 also drives the movement of the slider B5072. The slider B5072 slides along the guide rail B5071 to maintain the linear movement of the fixing block 5075. The fixing block 5075 can then be inserted into the fixing groove 5076 of the frame plate A502. During the insertion process, it also passes through the fixing through groove 5077 on the frame plate B504. The slot 5077 restricts the frame plate within the slot 503. At this time, the fixing screw B5078 on the frame plate A502 also passes through the through hole C5079 on the movable plate 5074. By rotating the nut clockwise, the nut is installed on the fixing screw B5078. The nut slowly presses against the surface of the movable plate 5074, thereby fixing the movable plate 5074 to the frame plate A502. This completes the operation of fixing the frame plate B504 within the slot 503. Conversely, by removing the nut and pulling the movable plate 5074 in the opposite direction to return to the initial position, the fixing of the frame plate B504 can be released. The disassembly and assembly operation is relatively simple.

[0056] Example 3

[0057] like Figures 1 to 3 As shown, this embodiment provides a first implementation method for the connecting and fixing component 4 in Embodiment 1:

[0058] The connecting and fixing assembly 4 includes fixing screws A401 fixed on the upper and lower sides of the busbar trunking body 1, and pressing screws 417 threaded to both sides of the cover plate 2. The cover plate 2 has through holes A402 for the fixing screws A401 to pass through. The fixing screws A401 press down on the heat-conducting plate 303 to promote the heat-conducting silicone pad 304 to adhere tightly to the surface of the busbar conductor.

[0059] The two cover plates 2 are passed through the fixing screws A401 on the upper and lower sides of the busbar trunking body 1, respectively. After passing through, the nut is rotated clockwise to install the nut on the fixing screw A401. The nut slowly presses against the surface of the cover plate 2, thereby fixing the cover plate 2 to the upper and lower sides of the busbar trunking body 1. After fixing, the handle 403 is rotated clockwise to turn the pressing screw 417, causing the two pressing screws 417 to move towards the middle and squeeze the heat-conducting plate 303. This allows the heat-conducting silicone pad 304 under the heat-conducting plate 303 to stick tightly to the surface of the busbar conductor in the busbar trunking body 1, thereby dissipating heat. The advantage of this structure is that there are almost no protruding structures that obstruct the installation of the busbar trunking body 1, and it can better cope with various narrow spaces.

[0060] Furthermore, a handle 403 is fixedly connected to the head of the pressing screw 417 to facilitate its rotation. An arc-shaped plate 416 is fixedly connected to the surface of the cover plate 2 on the side of the pressing screw 417. A screw 404 is threaded inside the arc-shaped plate 416. After the pressing state of the pressing screw 417 is adjusted, the screw 404 is rotated. The screw 404 moves along the arc-shaped plate 416 and slowly abuts against the outer wall of the pressing screw 417, thereby fixing the state of the pressing screw 417 and preventing it from rotating due to external force, which would affect the heat dissipation of the graphene heat dissipation component 3.

[0061] Example 4

[0062] like Figures 5 to 9 As shown, this embodiment provides a second implementation of the connecting and fixing component 4 in Embodiment 1:

[0063] The connecting and fixing assembly 4 includes a groove seat 405 fixed to the upper and lower sides of the busbar trunking body 1, and a through-slot seat 408. The bottom ends of the cover plate 2 are fixedly connected to two protrusions 406 that can be inserted into the groove seat 405. An elastic component 407 is also installed on both sides of the bottom end of the cover plate 2 within the area between the protrusions 406. The telescopic end of the elastic component 407 is fixed to the top surface of the heat-conducting plate 303. After the protrusions 406 are fully inserted into the groove seat 405, the elastic component 407 is in a compressed state, promoting the thermally conductive silicone pad 304 to adhere tightly to the surface of the busbar conductor through elasticity. A sliding rod 409 is fixedly connected inside the through-slot seat 408. Sliding sleeves 410 are slidably connected to the outer side walls of the sliding rod 409. The surface of the sliding sleeves 410 is fixed to the side end of the cover plate 2 via a connecting plate A411. The back of the through-slot seat 408... Both sides of the lower part are fixedly connected with horizontal plates 412, and connecting screws 413 are fixedly connected between the horizontal plates 412. The back of the sliding sleeve 410 is fixedly connected with a through plate 414. The through plate 414 has a through hole B415 for the connecting screw 413 to pass through. The elastic component 407 includes a lower open circular groove 4071 fixed to the bottom surface of the cover plate 2. Multiple springs 4072 are distributed in a circumferential array on the inner top wall of the lower open circular groove 4071. The head of the spring 4072 is fixedly connected to a circular plate 4075. A guide rail A4073 for sliding slider A4074 is fixedly connected to the inner surface of the lower open circular groove 4071. The surface of slider A4074 is fixed to the side end of circular plate 4075. The bottom of circular plate 4075 is fixed to the top of heat-conducting plate 303 through vertical rod 4076.

[0064] In the initial state, with the distance between the two cover plates 2 pulled to the maximum, the N-shaped structure formed by the two cover plates 2 and the connecting fixing component 4 can be inserted into the busbar trunking body 1. After insertion, the protrusion 406 on the cover plate 2 is aligned with the groove seat 405 on the busbar trunking body 1. Then, push the upper and lower cover plates 2 towards the middle. The cover plates 2 drive the sliding sleeve 410 to slide. The sliding sleeve 410 slides along the sliding rod 409 to maintain the linear movement of the cover plates 2. The sliding sleeve 410 drives the through plate 414 to move. As the connecting screw 413 moves along the connecting plate 414, the cover plate 2 simultaneously moves the two protrusions 406 towards the center, inserting the protrusions 406 into the recessed seat 405. After insertion, by rotating the nut on the connecting screw 413, the nut abuts against the top surface of the upper connecting plate 414 and the bottom surface of the lower connecting plate 414, thereby fixing the protrusions 406 in the recessed seat 405. During the insertion process, the thermally conductive silicone pad 304 under the heat-conducting plate 303 will first contact the motherboard in the busbar trunking body 1. The conductor contacts the vertical rod 4076, thereby applying a force in the direction of the downward-opening circular slot 4071 through the heat-conducting plate 303. This causes the circular plate 4075 to move inside the downward-opening circular slot 4071. The circular plate 4075 drives the slider A4074 to move. The slider A4074 slides along the guide rail A4073 to maintain the linear movement of the circular plate 4075, thereby compressing the spring 4072. The spring 4072 utilizes its elasticity to form a rebound force, allowing the thermally conductive silicone pad 304 to adhere tightly to the surface of the busbar conductor for heat dissipation. Compared with embodiment 3, this structure allows for the simultaneous installation of two cover plates 2 in one operation. When installing the cover plate 2, the thermally conductive silicone pad can be pressed tightly against the thermally conductive surface of the busbar without additional operations, making assembly more convenient. However, components such as the through slot 408 and the horizontal plate 412 are located outside the main body 1 of the busbar trunking, which will occupy a certain amount of space (these components are generally vertical strips and occupy a small amount of space), and may not be usable in some narrow spaces.

[0065] The present invention also provides an assembly method for the above-mentioned dense busbar based on graphene heat dissipation components (using the second type of connection and fixing component 4):

[0066] Step 1: Pull the distance between the two cover plates 2 to the maximum, and insert the N-shaped structure formed by the two cover plates 2 and the connecting fixing component 4 into the busbar trunking body 1. After insertion, the protrusion 406 on the cover plate 2 is aligned with the groove seat 405 on the busbar trunking body 1.

[0067] Step 2: Push the upper and lower cover plates 2 towards the middle. The cover plates 2 drive the sliding sleeve 410 to slide. The sliding sleeve 410 slides along the sliding rod 409 to maintain the linear movement of the cover plates 2. The sliding sleeve 410 drives the through plate 414 to move. The through plate 414 moves along the connecting screw 413. At the same time, the cover plates 2 drive the two protrusions 406 to move towards the middle. Insert the protrusions 406 into the groove seat 405. After insertion, rotate the nut on the connecting screw 413 so that the nut abuts against the top surface of the upper through plate 414 and the bottom surface of the lower through plate 414, thereby fixing the protrusions 406 in the groove seat 405.

[0068] Step 3: During the process of inserting the protrusion 406 into the groove seat 405, the thermally conductive silicone pad 304 under the heat-conducting plate 303 will first contact the bus conductor in the busbar trunk body 1. Thus, the heat-conducting plate 303 applies a force to the vertical rod 4076 in the direction of the downward-opening circular groove seat 4071, thereby driving the circular plate 4075 to move inside the downward-opening circular groove seat 4071. The circular plate 4075 drives the slider A4074 to move. The slider A4074 slides along the guide rail A4073 to maintain the linear movement of the circular plate 4075, thereby squeezing the spring 4072. The spring 4072 uses its elasticity to form a rebound force, so that the thermally conductive silicone pad 304 can stick to the surface of the bus conductor for heat dissipation.

[0069] Step 4: Insert the frame plate B504 into the frame groove 503. After insertion, the dustproof net 506 will be exactly opposite the opening groove 501.

[0070] Step 5: Move the movable plate 5074 towards the frame plate A502. The movable plate 5074 drives the fixed block 5075 to move, and at the same time, the movable plate 5074 also drives the slider B5072 to move. The slider B5072 slides along the guide rail B5071 to maintain the linear movement of the fixed block 5075. The fixed block 5075 can then be inserted into the fixing groove 5076 of the frame plate A502. During the insertion process, it also passes through the fixing groove on the frame plate B504. Through slot 5077, the frame plate is confined in frame slot 503. At this time, the fixing screw B5078 on frame plate A502 also passes through through hole C5079 on moving plate 5074. By rotating the nut clockwise, the nut is installed on the fixing screw B5078, thereby fixing moving plate 5074 to frame plate A502. This completes the operation of fixing frame plate B504 in frame slot 503, and finally completes the assembly of high-density busbar trunking.

[0071] The dense busbar trunking based on graphene heat dissipation components and its assembly method of the present invention have the following advantages:

[0072] The additional heat dissipation structure can assist the traditional ventilation structure 5 in heat dissipation, enhance the heat dissipation effect of the dense busbar trunking. Furthermore, the assembly method of this invention is simple and feasible. Most of the additional structures are set inside the dense busbar trunking, which does not occupy installation space and can be applied to various narrow spaces. Moreover, the filter screen on the ventilation structure 5 is installed in a concave-convex fit to reduce installation gaps and improve dust prevention.

[0073] The movable plate 5074 is pushed to move towards the frame plate A502. The movable plate 5074 drives the fixed block 5075 to move, and at the same time, the movable plate 5074 also drives the slider B5072 to move. The slider B5072 slides along the guide rail B5071 to maintain the linear movement of the fixed block 5075. The fixed block 5075 can then be inserted into the fixing groove 5076 of the frame plate A502. During the insertion process, it also passes through the fixing through groove 5077 on the frame plate B504, thereby confining the frame plate in the frame groove 503. At this time, the frame plate A502... The fixing screw B5078 on 502 also passes through the through hole C5079 on the movable plate 5074. By turning the nut clockwise, the nut is installed on the fixing screw B5078, thereby fixing the movable plate 5074 to the frame plate A502. This completes the operation of fixing the frame plate B504 in the frame groove 503. Conversely, by removing the nut and pulling the movable plate 5074 in the opposite direction to return to the initial position, the fixing of the frame plate B504 can be released. The disassembly and assembly operation is relatively simple and does not require the alignment operation of the fixing block 5075.

[0074] Two specific implementation methods for the connecting and fixing component 4 are given. The first method has almost no protruding structure that obstructs the installation of the busbar trunking body 1, and can better cope with various narrow spaces. The second method allows two cover plates 2 to be installed at the same time in one operation. When installing the cover plate 2, the thermal conductive silicone pad can be pressed tightly against the thermal conductive surface of the busbar. No extra operation is required, and the assembly operation is more convenient. The staff can choose to use it as needed.

Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention.
