[0038] Specifically, in use, each electrical equipment is installed into the plurality of mounting slots 2, so that the electrical equipments are not easy to cause electromagnetic interference with each other, and the use is more stable and safe. During use, the electrical equipment in the mounting slot 2 will transfer heat to the cabinet body 1, at which time the heat dissipation fan 5 is started, the heat dissipation fan 5 blows air to the heat dissipation groove 4, so that the heat dissipation groove 4 can dissipate heat, and the cabinet body 1 can be effectively cooled to ensure the stability of the operation of the electrical equipment. During the cooling period, the filter screen 6 at the air inlet end of the rectangular frame 29 can filter out part of the dust in the air to prevent the dust from quickly polluting the heat dissipation groove 4.

[0039] Embodiment two:

[0040] Referring to Figures 2-6 The same as embodiment one, and further, a specific implementation scheme for improving the heat dissipation efficiency is specifically added.

[0041] The inner bottom of the mounting groove 2 is fixedly connected with a plurality of first heat-conducting plates 7 arranged at equal intervals, the number of the first heat-conducting plates 7 is 6-20, and the preferred number is 12. A first cavity 27 is arranged in each of the plurality of first heat-conducting plates 7. The upper end of the first heat-conducting plate 7 is provided with a first air exchange hole 8 in communication with the first cavity 27. An air exchange component is arranged in the first cavity 27 to intermittently inhale and exhale air through the first air exchange hole 8

[0042] Specifically, during use, the first heat-conducting plates 7 on the inner bottom of the mounting groove 2 can effectively increase the heat-conducting area, so that heat can be quickly transferred to the cabinet 1 and the heat dissipation groove 4, thereby improving the heat dissipation efficiency of the cabinet 1, improving the heat dissipation efficiency of the electrical equipment, and making the electrical equipment run more stably. The air exchange component can make the first air exchange holes 8 on both sides inhale and exhale air alternately, so that the air in the mounting groove 2 can be continuously exchanged with the air in the first cavity 27, thereby significantly improving the air flow in the mounting groove 2 and improving the heat dissipation efficiency of the electrical equipment in the mounting groove 2.

[0043] The air exchange component includes a plurality of reciprocating lead screws 10 rotatably connected in the plurality of first cavities 27. The number of the reciprocating lead screws 10 is the same as that of the first heat-conducting plates 7. The outer wall of each reciprocating lead screw 10 is threadedly connected with a piston plate 9. The outer wall of the piston plate 9 is attached to the inner wall of the first cavity 27. The outer wall of the cabinet 1 is fixedly provided with a driving motor 11. The output shaft of the driving motor 11 is fixedly connected with one end of one of the reciprocating lead screws 10. The adjacent two reciprocating lead screws 10 are connected through two mutually meshing transmission gears 12.

[0044] Specifically, during heat dissipation, the driving motor 11 is started, which drives the reciprocating lead screw 10 to rotate. The reciprocating lead screw 10 drives the plurality of reciprocating lead screws 10 to synchronously rotate through the plurality of mutually meshing transmission gears 12. The plurality of reciprocating lead screws 10 drives the plurality of piston plates 9 to reciprocally slide in the first cavity 27. When the piston plate 9 slides to one end of the first cavity 27, a positive pressure is generated at the one end of the first cavity 27, and a negative pressure is generated at the other end. The first air exchange hole 8 in communication with the negative pressure end inhales air in the mounting groove 2, and the first air exchange hole 8 in communication with the positive pressure end exhales air into the mounting groove 2. Thus, the reciprocally sliding piston plate 9 makes the first air exchange holes 8 on both sides inhale and exhale air alternately, so that the air in the mounting groove 2 can be continuously exchanged with the air in the first cavity 27, thereby significantly improving the air flow in the mounting groove 2 and improving the heat dissipation efficiency of the electrical equipment in the mounting groove 2.

[0045] The two ends of the first heat-conducting plate 7 are fixedly connected with second heat-conducting plates 13 perpendicular thereto. The second heat-conducting plates 13 are provided with second cavities 28 in communication with the first cavities 27. The opposite surfaces of the two second heat-conducting plates 13 are provided with second air exchange holes 14.

[0046] Specifically, in practice, the second heat-conducting plate 13 at both ends of the first heat-conducting plate 7 can further improve the heat dissipation area, so that the electrical equipment in the cabinet body 1 can be more efficient in heat dissipation, and the second air exchange holes 14 on both sides can also take turns to inhale and exchange air, so that the air in the installation groove 2 can be better flowing and dissipating heat, and the heat dissipation efficiency of the electrical equipment can be significantly improved.

[0047] Example Three:

[0048] Referring to Figure 7 With Figure 8 The same as example two, further, the specific implementation scheme for improving the heat dissipation efficiency of the heat dissipation groove 4 is specifically added.

[0049] A plurality of third heat-conducting plates 15 are fixedly connected in the heat dissipation groove 4, the number of the third heat-conducting plates 15 is 6-20, and the preferred number of the third heat-conducting plates 15 is 12, the installation frame 16 is slidingly installed in the heat dissipation groove 4, the cleaning brush 17 is arranged on the outer wall of the third heat-conducting plate 15 on both sides of the installation frame 16, the installation frame 16 is connected with the piston plate 9 through the connecting part, the connecting part includes the slot 26 arranged on the top of the installation frame 16, the first magnet 18 is fixedly installed in the slot 26, and the piston plate 9 is magnetically attracted to the first magnet 18.

[0050] Specifically, in the use process of the heat dissipation groove 4, the plurality of third heat-conducting plates 15 in the heat dissipation groove 4 can further improve the heat dissipation area, so as to achieve the purpose of improving the heat dissipation effect, and during the reciprocating sliding of the piston plate 9, the piston plate 9 will attract the first magnet 18, so as to drive the first magnet 18 to reciprocate, the first magnet 18 will drive the installation frame 16 to reciprocate in the heat dissipation groove 4, and the installation frame 16 will drive the cleaning brush 17 to reciprocate on the surface of the third heat-conducting plate 15, so as to guarantee the heat conduction efficiency of the third heat-conducting plate 15, and indirectly guarantee the heat dissipation efficiency of the electrical equipment.

[0051] Example Four:

[0052] Referring to Figures 7-9 The same as example three, further, the specific implementation scheme for cleaning the third heat-conducting plate 15 is specifically added.

[0053] Both sides of the mounting frame 16 are provided with a sliding groove 19, and the mounting plate 20 is slidably installed in the two sliding grooves 19. The elastic column 21 is installed between the mounting plate 20 and the inner wall of the sliding groove 19. The heat dissipation groove 4 is provided with a shaking part for driving the mounting plate 20 to reciprocatingly slide along the sliding groove 19. The shaking part includes the horizontal rod 22 fixedly connected in the heat dissipation groove 4, the horizontal rod 22 penetrates the mounting frame 16, and the second magnet 23 is fixedly connected to the horizontal rod 22 at equal intervals. When the mounting plate 20 approaches the second magnet 23, the mounting plate 20 slides towards the second magnet 23

[0054] Specifically, during the reciprocating sliding of the mounting frame 16, the mounting frame 16 drives the mounting plate 20 to sequentially sweep through the plurality of second magnets 23. When the mounting plate 20 approaches the second magnet 23, the mounting plate 20 slides towards the second magnet 23, thereby driving the cleaning brush 17 to move away from the outer wall of the third heat conduction plate 15. When the mounting plate 20 moves away from the second magnet 23, the elastic column 21 drives the mounting plate 20 to slide reversely and reset. Therefore, when the mounting plate 20 sequentially passes through the plurality of second magnets 23, the mounting plate 20 reciprocatingly slides in the sliding groove 19, thereby driving the cleaning brush 17 to reciprocatingly shake on the surface of the third heat conduction plate 15. On the one hand, the dust on the cleaning brush 17 can be shaken off, and on the other hand, the cleaning effect of the third heat conduction plate 15 can be improved, thereby indirectly maintaining the better heat dissipation efficiency of the third heat conduction plate 15.

[0055] The outer wall of the mounting frame 16 is provided with the air inlet hole 25 communicated with the sliding groove 19, and the outer wall of the mounting plate 20 is provided with the air outlet hole 24 facing the cleaning brush 17. The one-way valve is fixedly installed in the air inlet hole 25 and the air outlet hole 24.

[0056] Specifically, when the mounting plate 20 slides into the sliding groove 19, the air in the sliding groove 19 is extruded and blown to the cleaning brush 17 through the air outlet hole 24. On the one hand, the cleaning brush 17 can be cleaned, and on the other hand, the outer wall of the third heat conduction plate 15 can be cleaned. When the mounting plate 20 reversely slides and resets, the sliding groove 19 can suck the air through the air inlet hole 25.

[0057] The anti-electromagnetic interference power cabinet is used to install the electrical equipment into the mounting slots 2, so that the electrical equipment is not easy to cause electromagnetic interference between each other, and the use is more stable and safe. During use, the electrical equipment in the mounting slot 2 can transmit heat to the cabinet 1. At this time, the heat dissipation fan 5 is started, and the heat dissipation fan 5 blows air to the heat dissipation groove 4, so that the heat dissipation groove 4 can be cooled, thereby effectively cooling the cabinet 1 to ensure the operation stability of the electrical equipment. During cooling, the filter screen 6 of the rectangular frame 29 can filter part of the dust in the air to prevent the dust from rapidly polluting the heat dissipation groove 4.

[0058] During use, the first heat-conducting plate 7 at the bottom of the installation groove 2 can effectively increase the heat-conducting area, so that heat can be transferred to the cabinet 1 and the heat dissipation groove 4 more quickly, so as to improve the heat dissipation efficiency of the cabinet 1, thereby improving the heat dissipation efficiency of the electrical equipment and making the electrical equipment run more stably.

[0059] During heat dissipation, the driving motor 11 is started, the driving motor 11 drives the reciprocating lead screw 10 to rotate, the reciprocating lead screw 10 drives the plurality of reciprocating lead screws 10 to rotate synchronously through the plurality of transmission gears 12 that are engaged with each other, and the plurality of reciprocating lead screws 10 drive the plurality of piston plates 9 to reciprocate in the first cavity 27. When the piston plate 9 slides to one end of the first cavity 27, a positive pressure is generated at one end of the first cavity 27, and a negative pressure is generated at the other end. The first air exchange hole 8 connected to the negative pressure end sucks the air in the installation groove 2, and the first air exchange hole 8 connected to the positive pressure end discharges the air into the installation groove 2. Thus, the reciprocating piston plate 9 makes the two first air exchange holes 8 alternately inhale and exhale, so that the air in the installation groove 2 can be continuously exchanged with the air in the first cavity 27, thereby significantly improving the air flow in the installation groove 2 and improving the heat dissipation efficiency of the electrical equipment in the installation groove 2.

[0060] In practice, the second heat-conducting plate 13 at both ends of the first heat-conducting plate 7 can further improve the heat dissipation area, so that the electrical equipment in the cabinet 1 can be more efficiently cooled, and the second air exchange holes 14 on both sides can also alternately inhale and exhale, so that the air in the installation groove 2 can be better circulated and cooled, thereby significantly improving the heat dissipation efficiency of the electrical equipment.

[0061] During use of the heat dissipation groove 4, the plurality of third heat-conducting plates 15 in the heat dissipation groove 4 can further improve the heat dissipation area, thereby achieving the purpose of improving the heat dissipation effect. During reciprocating sliding of the piston plate 9, the piston plate 9 can adsorb the first magnet 18, thereby driving the first magnet 18 to reciprocate, and the first magnet 18 drives the installation frame 16 to reciprocate in the heat dissipation groove 4, and the installation frame 16 drives the cleaning brush 17 to reciprocate on the surface of the third heat-conducting plate 15, so as to ensure the heat-conducting efficiency of the third heat-conducting plate 15 and indirectly ensure the heat dissipation efficiency of the electrical equipment.

[0062] During reciprocating sliding of the mounting frame 16, the mounting frame 16 will drive the mounting plate 20 to sweep through the second magnets 23 in sequence, when the mounting plate 20 approaches the second magnets 23, the mounting plate 20 will slide towards the second magnets 23, thereby driving the cleaning brush 17 to move away from the outer wall of the third heat-conducting plate 15, when the mounting plate 20 moves away from the second magnets 23, the elastic column 21 will drive the mounting plate 20 to slide reversely and reset, thus when the mounting plate 20 sweeps through the second magnets 23 in sequence, the mounting plate 20 will reciprocate in the sliding groove 19, thereby driving the cleaning brush 17 to reciprocate on the surface of the third heat-conducting plate 15, which can shake off the dust on the cleaning brush 17, and can improve the cleaning effect of the third heat-conducting plate 15, thereby indirectly keeping the third heat-conducting plate 15 to have better heat dissipation efficiency.

[0063] The above merely provides the preferred embodiments of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent substitution or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
