[0004] With regard to the above-mentioned related technologies, the inventors believe that in order to prevent dust, switch cabinets are mostly sealed with cabinet doors during use. Therefore, during operation, the temperature inside the switch cabinet is high and the heat is difficult to dissipate, that is, the heat dissipation effect is poor. When the temperature inside the switch cabinet reaches a certain value, it is easy to cause equipment failure, equipment aging, etc., that is, there is room for improvement. Summary of the invention

[0005] In order to improve the heat dissipation effect of a switch cabinet, the present application provides a switch cabinet with efficient heat dissipation.

[0008] By adopting the above technical solution, during the operation of the switch cabinet, the fan is started and the fan performs exhaust operation to remove all the heat inside the cabinet. In this process, the driving component is used to drive all the rotating rods to rotate, thereby adjusting the rotation angle of the blinds to guide the wind direction, thereby helping to focus on the heat dissipation of the parts with more electrical components. That is, the use of fans and blinds helps to improve the heat dissipation function of the switch cabinet, that is, helps to prevent equipment failure and equipment aging.

[0010] By adopting the above technical solution, the driving cylinder is operated, and the driving cylinder drives the rack to move. Since the rack is engaged with all the gears, the rack will drive all the gears to rotate, and then drive all the rotating rods to rotate, so as to adjust the angle of the blinds. This helps to align the blinds' air outlets with the parts with more electrical components in the cabinet, and thus helps to focus the heat dissipation on the parts with high temperatures.

[0011] Preferably, a sliding block is integrally formed on the rack, a sliding groove is provided on the lap plate at a position corresponding to the sliding block, and the sliding block is slidingly matched with the sliding groove.

A controller is arranged in the cabinet for controlling the operation of the driving cylinder, and all the temperature sensors are connected to the controller signal.

[0020] By adopting the above technical solution, during the operation of the switch cabinet, when the operating temperature of an electrical component in a certain part of the installation space on the upper part of the cabinet is high and reaches a certain value, the corresponding temperature sensor will transmit a signal to the controller, so that the controller controls the operation of the drive cylinder, thereby causing the blinds to rotate and align the air outlet of the blinds with the part with higher temperature, which helps to quickly dissipate heat at the part with higher temperature in the cabinet.

[0021] Preferably, a rectangular frame is provided in the middle of the cabinet body, and the two partitions are located on the inner side of the rectangular frame.

[0024] The drive component is used to adjust the angle of the blinds to guide the wind direction, thereby quickly dissipating the heat in the high-temperature areas. When the temperature inside the switch cabinet is low, there is no need to turn on the fan. The drive component is only needed to drive the blinds to swing back and forth to generate a small amount of air to dissipate the heat inside the cabinet. The swinging of the blinds back and forth helps prevent dust from accumulating on the blinds due to static electricity.

[0025] The partition is removable, which helps to replace partitions of different specifications to change the size of the connecting gap. The lap plate is removable, which helps to adapt to partitions of different specifications. In addition, the rotating rod and the blinds are removable, which is convenient for installing blinds with appropriate number of blades according to the size of the connecting gap. That is, the removability of multiple parts helps to improve the fault tolerance of the cabinet and facilitates the staff to assemble and disassemble the cabinet;

[0026] The temperature of the electrical components at various locations inside the cabinet is monitored in real time through the temperature sensor, and then fed back to the controller, so that the driving cylinder drives the shutter to rotate, so that the air outlet is aimed at the location with higher temperature, which helps to dissipate heat in time at the location with higher temperature inside the cabinet.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 2-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a switch cabinet with efficient heat dissipation.

[0034] Reference Figure 2 and Figure 3The switch cabinet with efficient heat dissipation includes a cabinet body 1 and a cabinet door 2. Two cabinet doors 2 are provided and are both hinged on the cabinet body 1 to realize the opening and closing control of the cabinet body 1. A rectangular frame 3 is installed in the middle of the cabinet body 1. The cabinet body 1 is located on the inner side of the rectangular frame 3 and is detachably connected with a partition 4. Two partitions 4 are provided and are both horizontally arranged. The two partitions 4 divide the interior of the cabinet body 1 into two upper and lower installation spaces 11. A connecting gap 41 that connects the two installation spaces 11 is formed between the two partitions 4. A fan 12 is installed on the top of the cabinet 1, and a plurality of air inlet holes 13 are opened at the lower part of the cabinet 1. The cabinet 1 is detachably connected with a shutter 5 in the connecting gap 41, and each curtain piece of the shutter 5 is fixedly connected with a rotating rod 6. The length direction of all the rotating rods 6 is parallel to the rotation axis direction of the curtain piece of the shutter 5. The cabinet 1 is provided with lap plates 7 at both ends of the rotating rod 6, and any lap plate 7 can be detachably connected to the two partitions 4. Any rotating rod 6 is rotatably connected to the two lap plates 7, and a driving component 8 for driving all the rotating rods 6 to rotate synchronously is provided on the partition 4.

[0035] In practice, during the operation of the switch cabinet, the fan 12 is started, and the fan 12 performs exhaust operation to extract the heat in the cabinet body 1. In this process, the driving assembly 8 is used to drive all the rotating rods 6 to rotate, and then the rotation angle of the shutter 5 is adjusted, that is, the air outlet direction of the shutter 5 is adjusted to face the part with more heat, that is, the wind is guided to help focus on the heat dissipation of the position with higher temperature. The fan 12 and the shutter 5 are used to improve the heat dissipation function of the switch cabinet, that is, to help prevent equipment failure and equipment aging.

[0036] Reference Figure 2 and Figure 3 A mounting groove 31 is provided on the inner side of the rectangular frame 3, and the mounting groove 31 is set as a T-slot. A plurality of nuts 311 are slidably provided in the mounting groove 31. Fixing holes 42 are provided around any partition 4. A bolt 43 is provided in the fixing hole 42 of any partition 4 close to the rectangular frame 3. The bolt 43 passes through the fixing hole 42 and is threadedly connected with the corresponding nut 311, thereby realizing the detachable connection of the partition 4. When the heat dissipation demand in the switch cabinet is large, a different partition 4 is replaced to increase the connecting gap 41, that is, to increase the air volume, which is helpful to improve the heat dissipation capacity. In addition, the nut 311 can slide in the mounting groove 31, and can adapt to partitions 4 of different specifications to realize the fixing operation of different partitions 4.

[0037] Reference Figure 3 and Figure 4, plug-in blocks 71 are integrally formed at both ends of any lap plate 7, and plug-in slots 44 are provided at positions corresponding to the plug-in blocks 71 of the two partitions 4, and the plug-in blocks 71 are plugged and matched with the corresponding plug-in slots 44 to realize the detachable connection between the lap plate 7 and the partition 4. Among them, the shutter 5, the lap plate 7 and the partition 4 are all detachably connected, which is convenient for the staff to assemble and disassemble the switch cabinet.

[0038] Reference Figure 3 and Figure 4 Any lap plate 7 is provided with a plurality of rotation grooves 72 corresponding to the number of rotation rods 6, and the two ends of any rotation rod 6 are respectively rotatably connected in the corresponding two rotation grooves 72, so as to realize the rotation coordination between the rotation rod 6 and the lap plate 7, that is, to realize the rotation of all the blades of the venetian blind 5. Any rotation groove 72 is set in a U-shaped opening, which is convenient for the staff to disassemble the venetian blind 5. When the connecting gap 41 changes, the size of the connecting gap 41 can be adapted by disassembling or installing an appropriate amount of venetian blind 5 blades.

[0039] Reference Figure 2 and Figure 3 The driving assembly 8 includes a gear 81, a rack 82 and a driving cylinder 83. There are multiple gears 81 corresponding to the number of rotating rods 6. Any gear 81 is coaxially fixed on the corresponding rotating rod 6 and is located at the end of the rotating rod 6 close to the inner side of the cabinet 1. The rack 82 is located at the lower side of all the gears 81 and meshes with all the gears 81. The length direction of the rack 82 is perpendicular to the length direction of the rotating rod 6. A sliding block 821 is integrally formed at the bottom of the rack 82. The lap plate 7 located on the inner side of the cabinet 1 is provided with a sliding groove 73 corresponding to the sliding block 821. The sliding block 821 slides with the sliding groove 73. The sliding direction of the sliding block 821 is parallel to the length direction of the rack 82. The driving cylinder 83 is installed on one of the partitions 4. The end of the piston rod of the driving cylinder 83 is fixedly connected to the end of the rack 82, and the telescopic direction of the piston rod of the driving cylinder 83 is parallel to the length direction of the rack 82. The driving cylinder 83 can be installed on the partition 4 by means of bolts 43 to form a detachable connection, which is convenient for installation and disassembly.

[0040] In practice, the driving cylinder 83 is operated, and the driving cylinder 83 drives the rack 82 to move. Since the rack 82 is meshed with all the gears 81, the rack 82 will drive all the gears 81 to rotate, and then drive all the rotating rods 6 to rotate, so as to adjust the angle of the blinds 5, which helps to align the air outlet of the blinds 5 with the higher temperature part in the cabinet 1, and helps to dissipate the heat in the high temperature part in time. In addition, when the temperature in the switch cabinet is low, it is not necessary to turn on the fan 12, and it is only necessary to drive the cylinder 83 to operate continuously, so that the blinds 5 are constantly swinging, and a small amount of heat dissipation can be performed.

[0041] Reference Figure 1A plurality of temperature sensors 9 are installed in the installation space 11 located at the upper part of the cabinet 1. In the present application, three temperature sensors 9 are taken as an example. The three temperature sensors 9 are horizontally spaced apart in the cabinet 1. A controller 10 is also installed in the cabinet 1 for controlling the operation of the driving cylinder 83. The three temperature sensors 9 are all connected to the controller 10 by signal.

[0042] When the temperature of a certain part on the upper part of the cabinet 1 is high, the temperature sensor 9 at the corresponding position will promptly feed back a signal to the controller 10, and the controller 10 will control the driving cylinder 83 to operate so that the air outlet of the shutter 5 faces the position with higher temperature, thereby facilitating rapid and timely targeted heat dissipation operations inside the cabinet 1.

[0043] The implementation principle of the switch cabinet with efficient heat dissipation in the embodiment of the present application is as follows: when the electrical components in the switch cabinet are all running, a large amount of heat will be generated inside. At this time, the fan 12 is started to exhaust the inside of the cabinet 1, so that the internal heat is extracted with the wind, thereby playing a heat dissipation function inside the cabinet 1. When the internal temperature is relatively low, the fan 12 can be turned off, and the driving cylinder 83 can be started to make the piston rod of the driving cylinder 83 move back and forth, that is, drive the shutter 5 to swing back and forth, generate wind force, and dissipate heat from the upper and lower parts of the cabinet 1. Using this method helps to improve the heat dissipation function of the switch cabinet, that is, it helps to prevent equipment failure and equipment aging.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
