DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Embodiment 1:

[0037] Reference Figure 1-Figure 9 , an anti-electromagnetic interference power cabinet, including a cabinet body 1 made of metal material, using a metal shell as a physical barrier to prevent external electromagnetic fields from entering the interior of the distribution cabinet, and also including: a plurality of equally spaced installation slots 2, all arranged on the front face of the cabinet body 1, the installation slots 2 are used to install electrical equipment in the cabinet body 1, the number of the installation slots 2 is 3-8, and the preferred number in this application is 3, wherein the front ports of the plurality of installation slots 2 are all installed with cabinet doors 3, the cabinet doors 3 are used to block the installation slots 2, and the material of the cabinet doors 3 is the same as that of the cabinet body 1; a plurality of heat dissipation slots 4 are arranged on the side wall of the cabinet body 1, the number of the heat dissipation slots 4 is the same as the number of the installation slots 2, wherein the plurality of heat dissipation slots 4 are respectively located below the installation slots 2, and ventilation components are arranged in the plurality of heat dissipation slots 4, the ventilation components include a rectangular frame 29 fixedly connected to one end of the heat dissipation slot 4, a heat dissipation fan 5 is fixedly installed in the rectangular frame 29, a filter screen 6 for filtering dust is fixedly installed at the air intake end of the rectangular frame 29, and an isolation net 30 for protecting the heat dissipation slot 4 is fixedly installed at the other end of the heat dissipation slot 4.

[0038] Specifically, when in use, each electrical device is installed in a plurality of mounting slots 2 respectively, so that it is not easy for each electrical device to cause electromagnetic interference to each other, and it is more stable and safe to use. During use, the electrical equipment in the mounting slot 2 will transfer heat to the cabinet 1. At this time, the cooling fan 5 is started, and the cooling fan 5 will blow air to the cooling slot 4, so that the cooling slot 4 can dissipate the heat. The cooling slot 4 can effectively dissipate the heat of the cabinet 1 to ensure the operating stability of the electrical equipment. During the heat dissipation period, the filter 6 at the air intake end of the rectangular frame 29 can filter out some dust in the air to prevent the dust from quickly contaminating the cooling slot 4.

[0039] Embodiment 2:

[0040] Reference Figure 2-Figure 6 , which is basically the same as the first embodiment, and further, a specific implementation plan 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 in the present application is 12. A first cavity 27 is provided in each of the plurality of first heat conducting plates 7, wherein a first ventilation hole 8 communicating with the first cavity 27 is provided at the upper end of the first heat conducting plate 7, and a ventilation component is provided in the first cavity 27 to intermittently inhale and exhaust the first ventilation hole 8.

[0042] Specifically, during use, the first heat conduction plate 7 at the bottom of the mounting groove 2 can effectively increase the heat conduction area, so that the 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 operation of the electrical equipment more stable. The ventilation component will make the first ventilation holes 8 on both sides take turns to inhale and exhaust air, 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 thus improving the heat dissipation efficiency of the electrical equipment in the mounting groove 2.

[0043] The above-mentioned ventilation component includes a plurality of reciprocating screws 10 rotatably connected in a plurality of first cavities 27, the number of the reciprocating screws 10 is the same as the number of the first heat conducting plates 7, the outer wall of each reciprocating screw 10 is threadedly connected to a piston plate 9, the outer wall of the piston plate 9 is fitted to the inner wall of the first cavity 27, wherein a drive motor 11 is fixedly mounted on the outer wall of the cabinet 1, the output shaft of the drive motor 11 is fixedly connected to one end of one of the reciprocating screws 10, and two adjacent reciprocating screws 10 are connected by two mutually meshing transmission gears 12.

[0044] Specifically, during the heat dissipation period, the drive motor 11 is started, and the drive motor 11 will drive the reciprocating screw 10 to rotate. The reciprocating screw 10 will drive multiple reciprocating screws 10 to rotate synchronously through multiple mutually meshing transmission gears 12. The multiple reciprocating screws 10 will drive multiple piston plates 9 to slide back and forth in the first cavity 27. When the piston plate 9 slides toward one end of the first cavity 27, positive pressure will be generated at one end of the first cavity 27, and negative pressure will be generated at the other end. The first ventilation hole 8 connected to the negative pressure end will absorb the air in the installation groove 2, and the first ventilation hole 8 connected to the positive pressure end will exhaust air into the installation groove 2. Therefore, the reciprocatingly sliding piston plate 9 will cause the first ventilation holes 8 on both sides to take turns to inhale and exhaust air, 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 then improving the heat dissipation efficiency of the electrical equipment in the installation groove 2.

[0045] Both ends of the first heat conducting plate 7 are fixedly connected with second heat conducting plates 13 perpendicular thereto. A second cavity 28 communicating with the first cavity 27 is provided in the second heat conducting plate 13 . Second ventilation holes 14 are provided on opposite surfaces of the two second heat conducting plates 13 .

[0046] Specifically, in practice, the second heat conducting plates 13 at both ends of the first heat conducting plate 7 can further increase the heat dissipation area, so that the electrical equipment in the cabinet 1 can dissipate heat more efficiently, and the second ventilation holes 14 on both sides can also take turns to inhale and ventilate, so that the air in the installation slot 2 can flow and dissipate heat better, significantly improving the heat dissipation efficiency of the electrical equipment.

[0047] Embodiment three:

[0048] Reference Figure 7 and Figure 8 , which is basically the same as the second embodiment, and further, a specific implementation plan for improving the heat dissipation efficiency of the heat dissipation slot 4 is specifically added.

[0049] A plurality of third heat conducting plates 15 arranged at equal intervals 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 in the present application is 12. A mounting frame 16 is slidably installed in the heat dissipation groove 4, and cleaning brushes 17 are provided on both sides of the mounting frame 16 and are attached to the outer walls of the third heat conducting plates 15. The mounting frame 16 is connected to the piston plate 9 through a connecting portion, and the connecting portion includes a slot 26 opened at the top of the mounting frame 16, and a first magnet 18 is fixedly installed in the slot 26, and the piston plate 9 and the first magnet 18 are magnetically attracted to each other.

[0050] Specifically, during the use of the heat sink 4, the multiple third heat conduction plates 15 in the heat sink 4 can further increase its heat dissipation area, thereby achieving the purpose of improving the heat dissipation effect. During the reciprocating sliding of the piston plate 9, the piston plate 9 will adsorb the first magnet 18, thereby driving the first magnet 18 to slide back and forth, and the first magnet 18 will drive the mounting frame 16 to slide back and forth in the heat sink 4. The mounting frame 16 will drive the cleaning brush 17 to sweep back and forth on the surface of the third heat conduction plate 15 to ensure the thermal conductivity of the third heat conduction plate 15, thereby indirectly ensuring the heat dissipation efficiency of the electrical equipment.

[0051] Embodiment 4:

[0052] Reference Figure 7-Figure 9 , which is basically the same as the third embodiment, and further, a specific implementation scheme for cleaning the third heat conducting plate 15 is specifically added.

[0053] Both sides of the above-mentioned mounting frame 16 are provided with slide grooves 19, and mounting plates 20 are slidably installed in the two slide grooves 19. Elastic columns 21 are installed between the mounting plates 20 and the inner walls of the slide grooves 19. A shaking part for driving the mounting plate 20 to slide back and forth along the slide grooves 19 is provided in the heat dissipation groove 4. The shaking part includes a cross bar 22 fixedly connected to the heat dissipation groove 4. The cross bar 22 passes through the mounting frame 16. A plurality of second magnets 23 arranged at equal intervals are fixedly connected to the cross bar 22. When the mounting plate 20 approaches the second magnet 23, the mounting plate 20 slides toward the second magnet 23.

[0054] Specifically, during the reciprocating sliding of the mounting frame 16, the mounting frame 16 will drive the mounting plate 20 to scan multiple second magnets 23 in sequence. When the mounting plate 20 is close to the second magnet 23, the mounting plate 20 will slide in the direction of the second magnet 23, thereby driving the cleaning brush 17 away from the outer wall of the third heat conducting plate 15. When the mounting plate 20 is away from the second magnet 23, the elastic column 21 will drive the mounting plate 20 to slide in the opposite direction and reset. Therefore, when the mounting plate 20 passes through multiple second magnets 23 in sequence, the mounting plate 20 will slide back and forth in the slide groove 19, thereby driving the cleaning brush 17 to shake back and forth on the surface of the third heat conducting plate 15. On the one hand, the dust on the cleaning brush 17 can be shaken off, and on the other hand, the effect of cleaning the third heat conducting plate 15 can be improved, which can indirectly enable the third heat conducting plate 15 to maintain better heat dissipation efficiency.

[0055] The outer wall of the mounting frame 16 is provided with an air inlet 25 connected to the slide slot 19 , and the outer wall of the mounting plate 20 is provided with an air outlet 24 facing the cleaning brush 17 , and one-way valves are fixedly installed in the air inlet 25 and the air outlet 24 .

[0056] Specifically, when the mounting plate 20 slides into the slide groove 19, the air in the slide groove 19 will be squeezed and blown toward the cleaning brush 17 through the exhaust 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 slides in the opposite direction to reset, the slide groove 19 will absorb air through the air inlet hole 25.

[0057] When the present anti-electromagnetic interference power cabinet is in use, each electrical device is installed in a plurality of installation slots 2 respectively, so that each electrical device is not easy to cause electromagnetic interference to each other, and the use is more stable and safe. During use, the electrical device in the installation slot 2 will transfer heat to the cabinet 1. At this time, the cooling fan 5 is started, and the cooling fan 5 will blow air to the heat dissipation slot 4, so that the heat dissipation slot 4 can be cooled. The heat dissipation slot 4 can effectively dissipate the heat of the cabinet 1 to ensure the operating stability of the electrical equipment. During the heat dissipation period, the filter 6 at the air intake end of the rectangular frame 29 can filter out some dust in the air to prevent the dust from quickly contaminating the heat dissipation slot 4.

[0058] During use, the first heat conduction plate 7 at the bottom of the installation groove 2 can effectively increase the heat conduction area, so that the 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 the heat dissipation period, the drive motor 11 is started, and the drive motor 11 will drive the reciprocating screw 10 to rotate. The reciprocating screw 10 will drive multiple reciprocating screws 10 to rotate synchronously through multiple mutually meshing transmission gears 12. Multiple reciprocating screws 10 will drive multiple piston plates 9 to slide back and forth in the first cavity 27. When the piston plate 9 slides toward one end of the first cavity 27, positive pressure will be generated at one end of the first cavity 27, and negative pressure will be generated at the other end. The first ventilation hole 8 connected to the negative pressure end will absorb the air in the installation groove 2, and the first ventilation hole 8 connected to the positive pressure end will exhaust air into the installation groove 2. Therefore, the reciprocatingly sliding piston plate 9 will cause the first ventilation holes 8 on both sides to take turns to inhale and exhaust air, 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 then improving the heat dissipation efficiency of the electrical equipment in the installation groove 2.

[0060] In practice, the second heat conducting plates 13 at both ends of the first heat conducting plate 7 can further increase the heat dissipation area, so that the electrical equipment in the cabinet 1 can dissipate heat more efficiently, and the second ventilation holes 14 on both sides can also take turns to inhale and ventilate, so that the air in the installation slot 2 can flow and dissipate heat better, significantly improving the heat dissipation efficiency of the electrical equipment.

[0061] During the use of the heat sink 4, the multiple third heat conducting plates 15 in the heat sink 4 can further increase its heat dissipation area, thereby achieving the purpose of improving the heat dissipation effect. During the reciprocating sliding of the piston plate 9, the piston plate 9 will adsorb the first magnet 18, thereby driving the first magnet 18 to slide back and forth, and the first magnet 18 will drive the mounting frame 16 to slide back and forth in the heat sink 4, and the mounting frame 16 will drive the cleaning brush 17 to sweep back and forth on the surface of the third heat conducting plate 15 to ensure the thermal conductivity of the third heat conducting plate 15, thereby indirectly ensuring the heat dissipation efficiency of the electrical equipment.

[0062] During the reciprocating sliding of the mounting frame 16, the mounting frame 16 will drive the mounting plate 20 to scan multiple second magnets 23 in sequence. When the mounting plate 20 is close to the second magnet 23, the mounting plate 20 will slide in the direction of the second magnet 23, thereby driving the cleaning brush 17 away from the outer wall of the third heat conducting plate 15. When the mounting plate 20 is away from the second magnet 23, the elastic column 21 will drive the mounting plate 20 to slide in the opposite direction and reset. Therefore, when the mounting plate 20 passes through multiple second magnets 23 in sequence, the mounting plate 20 will slide back and forth in the slide groove 19, thereby driving the cleaning brush 17 to shake back and forth on the surface of the third heat conducting plate 15. On the one hand, the dust on the cleaning brush 17 can be shaken off, and on the other hand, the effect of cleaning the third heat conducting plate 15 can be improved, which can indirectly enable the third heat conducting plate 15 to maintain better heat dissipation efficiency.
