Description

Technical Field

[0001] This utility model relates to the field of switch cabinets, and more specifically, to a heat dissipation mechanism for switch cabinets. Background Technology

[0002] Switchgear, as an important power distribution and control device in power systems, is widely used in various fields such as industry, construction, and energy. It typically houses electrical components such as circuit breakers, contactors, relays, and busbars, which generate a significant amount of heat during prolonged operation. If this heat is not dissipated effectively and promptly, the internal temperature of the cabinet will continue to rise, affecting the normal operation of the electrical components and potentially leading to equipment failure or safety accidents.

[0003] Based on the above, the inventors have discovered that the air ducts in existing switchgear heat dissipation structures are often designed in a relatively simple way, which may lack optimized layout of airflow paths, resulting in uneven heat dissipation in local areas and the formation of "hot spots"; moreover, some fans are fixedly installed, making it inconvenient to flexibly adjust the air supply direction according to actual needs, which reduces the adaptability and practicality of the system. Therefore, in view of this, the inventors have studied and improved the existing structure to provide a heat dissipation mechanism for switchgear, in order to achieve a more practical value.

[0028] Example:

[0029] Please see Figures 1-6 A heat dissipation mechanism for a switch cabinet includes a switch cabinet body 1. A pair of turbine blowers 2 are fixedly installed on both sides of the top of the switch cabinet body 1. Each pair of turbine blowers 2 has an air inlet pipe 3 fixedly connected to its outlet end, and one end of each pair of air inlet pipes 3 extends into the interior of the switch cabinet body 1. An air collection box 4 is fixedly installed on both sides of the top of the inner wall of the switch cabinet body 1. One end of the air inlet pipe 3 is fixedly connected to the outer wall of the air collection box 4, and the interior of the air inlet pipe 3 is interconnected with the interior of the air collection box 4. A pair of connecting pipes 5 are fixedly installed at the bottom of the air collection box 4. A splicing insert pipe 6 is inserted into the interior of the pair of connecting pipes 5. One end of the splicing insert pipe 6 is fixedly connected to a heat dissipation outlet pipe 7. Air guide nozzles 8 are evenly fixedly installed on the outer wall of the heat dissipation outlet pipe 7. A cylindrical filter screen 9 is inserted and installed inside the hot air outlet duct 7. Cavities 11 are evenly opened on the inner wall of the connecting pipe 5. A limit spring 12 is fixedly installed inside the cavity 11. A limit head 13 is fixedly installed at one end of the limit spring 12. Limit holes 14 are evenly opened on the outer wall of the splicing pipe 6. This device blows the heat dissipation airflow generated by the turbine blower 2 into the interior of the switch cabinet body 1 through the heat dissipation air outlet duct 7 and the air guide nozzle 8. The heat dissipation air outlet duct 7 can be rotated and disassembled. By rotating the heat dissipation air outlet duct 7, the entire space of the switch cabinet body 1 can be effectively covered, enhancing the overall heat dissipation capacity. At the same time, the cylindrical filter screen 9 can prevent dust from entering the interior of the switch cabinet body 1, improving the stability of the structure during operation and the adequacy of heat dissipation.

[0030] See Figure 1 , Figure 3 , Figure 4 , Figure 5Two sets of heat dissipation exhaust pipes 7 are located on both sides of the inner wall of the switch cabinet body 1, and the edge of one end of the heat dissipation exhaust pipe 7 is tightly fitted with the edge of one end of the connecting pipe 5. The outer wall of the splicing tube 6 is fitted with a sealing ring 10, and the cross-section of the sealing ring 10 is H-shaped. The two ends of the sealing ring 10 are tightly fitted with one end of the connecting pipe 5 and one end of the heat dissipation exhaust pipe 7, respectively. The sealing ring 10 covers the outer wall of the heat dissipation exhaust pipe 7 and the connecting pipe 5, and seals the gap between the connecting pipe 5 and the heat dissipation exhaust pipe 7 to prevent air leakage. One end of the limiting head 13 is inserted into the inside of the limiting hole 14, and both the end of the limiting head 13 and the limiting hole 14 are arc-shaped. Through the arc shape of the end of the limiting head 13 and the limiting hole 14, the splicing tube 6 can be fixed while rotating inside the connecting pipe 5, and it is also convenient for the staff to disassemble and maintain the heat dissipation exhaust pipe 7.

[0031] See Figure 2 , Figure 6 A drying box 15 is inserted into one side of the air collecting box 4 through an opening. The bottom of the inner wall of the drying box 15 is open, and baffle rods 16 are evenly fixedly installed at the bottom opening of the drying box 15. A sealing plate 18 is fixedly installed on one side of the drying box 15. A silica gel desiccant pack 17 is placed on the top of the baffle rods 16, and the silica gel desiccant pack 17 is located inside the drying box 15. By designing the bottom of the drying box 15 as open, airflow inside the air collecting box 4 can be effectively maintained, and it is convenient for staff to put the silica gel desiccant pack 17 into the drying box 15, ensuring airflow. The airflow is improved during dehumidification, and the silica gel desiccant pack 17 can effectively assist in drying the humidity in the airflow. Adsorption magnets 19 are fixedly installed on the edge of the open end of the air collecting box 4 and one side of the sealing plate 18. The two adsorption magnets 19 attract each other. By setting the adsorption magnets 19, after the drying box 15 is inserted into the air collecting box 4, the sealing plate 18 and one side of the air collecting box 4 are tightly fitted. At the same time, the adsorption magnets 19 on the air collecting box 4 and the adsorption magnets 19 on the sealing plate 18 attract each other, thereby improving the firmness and sealing of the air collecting box 4 and the drying box 15 after assembly.

[0032] In use: First, the operator pulls the drying box 15 out of the air collecting box 4. Then, the silica gel desiccant pack 17 is placed inside the drying box 15, and the drying box 15 is pushed into the air collecting box 4. At the same time, the sealing plate 18 is tightly attached to one side of the air collecting box 4, and the drying box 15 is fixed inside the air collecting box 4 using the adsorption magnet 19. Then, by pulling down the heat dissipation exhaust pipe 7, the splicing tube 6 is separated from the connecting pipe 5. The cylindrical filter 9 is inserted into the heat dissipation exhaust pipe 7 through the splicing tube 6. Then, one end of the splicing tube 6 is inserted into the connecting pipe 5. At the same time, the elasticity of the limiting spring 12 is used to spring the limiting head 13 into the limiting hole 14 on the outer wall of the splicing tube 6, thereby fixing the heat dissipation exhaust pipe 7 and the connecting pipe 5. After the connection is established, the turbine blower 2 starts working. The airflow generated by the turbine blower 2 will enter the air collection box 4 through the air inlet pipe 3. Then, the airflow will be dehumidified and dried by the silica gel desiccant pack 17. The airflow will then enter the heat dissipation air outlet pipe 7 and be blown into the interior of the switch cabinet body 1 through the air guide nozzle 8 on the heat dissipation air outlet pipe 7. By rotating the heat dissipation air outlet pipe 7, the splicing tube 6 will rotate inside the connecting pipe 5. After the rotation is completed, the elasticity of the limit spring 12 will cause the limit head 13 to spring into the interior of the limit hole 14, and the rotation angle of the heat dissipation air outlet pipe 7 will be fixed. The air delivery direction of the air guide nozzle 8 can be adjusted according to the distribution of the heat-generating elements inside the switch cabinet body 1, thereby achieving the purpose of heat dissipation inside the switch cabinet body 1.

Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
