[0001] This utility model relates to the field of heat dissipation guide plate technology, and in particular to a low-pressure cabinet ventilation and heat dissipation guide plate. Background Technology

[0002] In electrical equipment such as low-voltage switchgear, ventilation and heat dissipation are crucial for ensuring normal operation. With increasing power density and integration of electrical equipment, a significant amount of heat is generated during operation. If this heat cannot be dissipated effectively and promptly, it can lead to overheating, affecting performance and even causing equipment malfunction or damage.

[0003] Traditional heat dissipation designs typically rely on components such as heat sinks and fans. While these can achieve a certain level of heat dissipation, they also have some drawbacks. For example, heat sinks may take up a lot of space, affecting the overall layout of the equipment, and heat dissipation components may accumulate dust over time, reducing their heat dissipation efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a low-voltage cabinet ventilation and heat dissipation guide plate, which aims to improve the problem that heat dissipation components in the prior art may accumulate dust due to long-term use, reducing heat dissipation efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a low-voltage cabinet ventilation and heat dissipation guide plate, comprising a heat dissipation frame, a heat dissipation component fixedly connected inside the heat dissipation frame, the heat dissipation component being used to adsorb hot air inside the cabinet, grooves being provided on both sides of the front of the heat dissipation frame, a guide plate body being slidably connected inside the heat dissipation frame, plug-in plates being fixedly connected on both sides of the guide plate body, a support plate being fixedly connected on the opposite side of the plug-in plate, a connecting shaft being fixedly connected inside the support plate, a connecting sleeve being slidably connected outside the connecting shaft, a clamping plate being fixedly connected to the front side of the connecting sleeve, a connecting groove being provided on the opposite side of the plug-in plate, springs being fixedly connected on both sides of the inside of the connecting groove, the springs being fixedly connected to the adjacent side of the clamping plate, connecting blocks being fixedly connected on both sides of the heat dissipation frame, a plug-in groove being provided on the front side of the connecting block, and a through groove being provided on the opposite side of the plug-in groove.

[0006] As a further description of the above technical solution: The heat dissipation assembly includes a dustproof mesh, which is fixedly connected to the rear side of the inside of the heat dissipation frame. The inside of the heat dissipation frame is fixedly connected to evenly distributed heat dissipation fins.

[0007] As a further description of the above technical solution: The interior of the guide plate body is fixedly connected with a composite material layer, and both sides of the exterior of the composite material layer are fixedly connected with connecting components, which are used to enhance the heat resistance of the guide plate body.

[0008] As a further description of the above technical solution: The connecting component includes a heat insulation layer, which is fixedly connected to the outside of the composite material layer, and heat-conducting layers are fixedly connected to both sides of the outside of the heat insulation layer.

[0009] As a further description of the above technical solution: The plug plate is slidably connected inside the groove.

[0010] As a further description of the above technical solution: Both the plug plate and the support plate are slidably connected inside the plug slot, and the card plate is slidably connected inside the through slot.

[0011] As a further description of the above technical solution: Both the heat insulation layer and the heat conduction layer are fixedly connected to the inside of the guide plate body.

Then, the guide plate body is manually moved to drive the plug plate out of the plug groove. This makes it easy to disassemble and assemble the guide plate body, making it convenient to clean or maintain it, and improving the ease of use of the equipment.

[0014] 2. In this utility model, the composite material layer provides better heat dissipation performance and higher durability, the heat insulation layer is used to prevent heat propagation, and the heat conduction layer is used to accelerate heat conduction, thereby effectively improving heat dissipation performance and equipment reliability, and ensuring that the equipment can operate stably in different working environments.

The dustproof net 2 is fixedly connected to the rear side of the inside of the heat dissipation frame 1. Heat dissipation fins 3 are fixedly connected to the inside of the heat dissipation frame 1.

[0019] The dustproof net 2 prevents dust from entering the heat sink 3. The heat sink 3 absorbs the hot air inside the cabinet, and the guide plate body 5 guides and transports the hot air. By inserting a finger into the through slot 15, the locking plate 10 is pushed out of the through slot 15. At the same time, the locking plate 10 moves and causes the connecting sleeve 9 to slide outside the connecting shaft 8, thereby squeezing the spring 12. Then, the guide plate body 5 is manually moved to drive the plug plate 6 out of the plug slot 14, which facilitates the disassembly and assembly of the guide plate body 5.

[0020] Reference Figure 1 , Figure 3 , Figure 6 The interior of the deflector body 5 is fixedly connected to a composite material layer 16, and both sides of the exterior of the composite material layer 16 are fixedly connected to connecting components. The connecting components are used to enhance the heat resistance of the deflector body 5. The connecting components include a heat insulation layer 17, which is fixedly connected to the exterior of the composite material layer 16. Both sides of the exterior of the heat insulation layer 17 are fixedly connected to a heat-conducting layer 18.

[0021] The composite material layer 16 provides better heat dissipation performance and higher durability, the heat insulation layer 17 is used to prevent heat transmission, and the heat conduction layer 18 is used to accelerate heat conduction, which effectively improves heat dissipation performance and equipment reliability.

[0022] Reference Figures 1-6 The plug plate 6 is slidably connected inside the groove 4; the plug plate 6 and the support plate 7 are both slidably connected inside the plug slot 14, and the card plate 10 is slidably connected inside the through slot 15; the heat insulation layer 17 and the heat conduction layer 18 are both fixedly connected inside the guide plate body 5; the guide plate body 5 is located on the front side of the heat sink 3, and the heat sink 3 is located on the front side of the dustproof net 2.

The guide plate body 5 facilitates the guidance and delivery of hot air. By inserting a finger into the through slot 15, the locking plate 10 is moved, causing it to disengage from the through slot 15. Simultaneously, the movement of the locking plate 10 causes the connecting sleeve 9 to slide outside the connecting shaft 8, thereby compressing the spring 12. Then, manually moving the guide plate body 5 causes the insertion plate 6 to move, disengaging it from the insertion slot 14. This allows for easy disassembly and assembly of the guide plate body 5, facilitating cleaning or maintenance. The design enhances the ease of use of the equipment. The composite material layer 16 provides better heat dissipation performance and higher durability, achieving a good balance between heat dissipation performance and weight, making it suitable for environments with high heat dissipation requirements. The heat insulation layer 17 is mainly used to prevent heat transmission, reduce the impact of high external temperatures or internal overheating, protect the equipment from overheating damage, and maintain stable operation. The heat-conducting layer 18 is mainly used to accelerate heat conduction, helping heat to flow quickly from the heat source area to the heat dissipation area or the external environment, improving heat dissipation efficiency, maintaining the safe temperature of the equipment, and effectively improving heat dissipation performance and equipment reliability, ensuring stable operation of the equipment in different working environments.
