Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, specifically to a power distribution cabinet with automatic high-temperature temperature control and cooling function. Background Technology

[0002] Distribution cabinets are key equipment in power systems used for distributing, controlling, protecting, and monitoring electrical energy. They are widely used in industrial, commercial, building, and infrastructure sectors. Their main purpose is to divide the main power supply from transformers or generators into multiple branches to supply power to different electrical devices or areas.

[0003] Chinese Patent CN221447734U discloses a novel integrated intelligent power distribution cabinet, belonging to the field of power distribution cabinet technology. This novel integrated intelligent power distribution cabinet includes a main body and a cooling and dust removal component. The main body includes a cabinet box and a door. The door is located on the front of the cabinet box, and an exhaust component is installed on the top of the cabinet box. An air inlet is provided on the front of the door. The cooling and dust removal component includes grooves with an internal cavity structure, nozzles, and an air pressurization and delivery component. Multiple grooves are vertically arranged on the inside of the door. The exhaust component exhausts heat from inside the cabinet box to the outside, reducing the internal temperature. Simultaneously, the air pressurization and delivery component delivers pressurized air to the nozzles, which spray it onto the surface of the electrical components inside the power distribution cabinet. The nozzles cover the entire front area of ​​the cabinet interior, allowing for rapid cooling of electrical components in any area inside the cabinet, and the rapid airflow carries away surface dust.

[0004] While the aforementioned technical solution utilizes exhaust components for daily ventilation and cooling, and air pressurization and delivery components for further cooling of the distribution cabinet's interior, it suffers from several drawbacks. Firstly, the air pressurization and delivery components generate significant noise during air compression, which not only disrupts the working environment and negatively impacts worker health and efficiency but may also violate relevant noise control standards. Secondly, the air pressurization and delivery components can only release a fixed amount of compressed gas at a time, resulting in intermittent cooling. During gas compression, the control unit inside the distribution cabinet cannot effectively dissipate heat, leading to unstable cooling control and difficulty in maintaining the cabinet's internal temperature within a suitable range. Furthermore, frequent gas compression consumes substantial energy, increasing cooling costs and raising the distribution cabinet's operating expenses. Summary of the Invention

[0015] The advantages of this invention compared to the prior art are:

[0016] 1. This invention divides the internal space of the distribution cabinet into multiple independent installation areas by setting up multiple partition control plates inside the cabinet. Temperature sensors are installed on each partition control plate, enabling precise monitoring of the temperature of control units in different areas. During daily operation of the distribution cabinet, the air intake device delivers external air to the airflow channel, which then evenly diffuses the air to each installation area through multiple sets of air intake holes, carrying away heat. When the temperature sensor detects that the temperature in some areas is too high, the airflow control device immediately responds, reducing the airflow to the lower-temperature areas while increasing the airflow to the hotter areas. Simultaneously, the partition control plates close off the high-temperature areas to prevent heat diffusion and open the partition control plates in the low-temperature areas to allow airflow between them. This precise temperature control and efficient heat dissipation method ensures that all areas inside the distribution cabinet receive appropriate heat dissipation, avoiding equipment failure or performance degradation caused by localized overheating, effectively guaranteeing the stable operation of the distribution cabinet and extending the service life of the control units.

[0017] 2. Compared to the high energy consumption and high cost caused by the frequent gas compression of air pressurization and delivery components in traditional technical solutions, this invention adopts a combination of air intake device and air control and adjustment device to achieve adaptive airflow distribution. By monitoring the temperature of each installation area in real time and automatically adjusting the air intake according to the temperature, unnecessary energy waste is avoided. At the same time, this invention does not require frequent gas compression processes, which greatly reduces energy consumption and thus significantly reduces the heat dissipation cost of the distribution cabinet. In addition, because this invention can more effectively maintain the temperature inside the cabinet within a suitable range, it reduces equipment damage and maintenance costs caused by excessive temperature, further improving the overall operating efficiency of the distribution cabinet.

[0032] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0033] See Figures 1 to 12 As shown, a power distribution cabinet 1 with high-temperature automatic temperature control and cooling function includes a directional temperature control device installed on the power distribution cabinet 1. The directional temperature control device includes multiple partition control plates 4 distributed inside the power distribution cabinet 1. Each partition control plate 4 is equipped with a temperature sensor. The multiple partition control plates 4 are used to divide the inside of the power distribution cabinet 1 into multiple installation areas. An air inlet side plate 2 is also installed on the side of the power distribution cabinet 1. The side of the air inlet side plate 2 is provided with multiple sets of air inlet holes 21. Each set of air inlet holes 21 is connected to the corresponding installation area. An airflow channel is provided inside the airflow channel. An air control adjustment device 3 is installed inside the airflow channel. The air control adjustment device 3 is used to adjust the air intake of the air inlet holes 21. An air intake device 5 is also installed on the side of the air inlet side plate 2. The directional temperature control device also includes an air outlet side plate 6 installed on the side of the power distribution cabinet 1 away from the air inlet side plate 2. The air outlet side plate 6 is used to guide the air inside the power distribution cabinet 1 to be discharged.

[0034] Multiple partition control panels 4 are distributed inside the distribution cabinet 1, dividing the cabinet space into multiple installation areas and enabling independent management of control units in different areas. Each partition control panel 4 is equipped with a temperature sensor to monitor the temperature of the corresponding installation area in real time.

[0035] During normal operation of the distribution cabinet 1, the air intake device 5 is activated, delivering outside air to the airflow channel. The airflow channel guides the air to various installation areas through multiple sets of air inlets 21. Each set of air inlets 21 has multiple guide vanes 22 installed at its outlet end to evenly diffuse the airflow and ensure that air enters the installation area uniformly. As the air passes through the installation area, it carries away heat from the installation area, reducing the temperature of the control unit 7.

[0036] Temperature sensors monitor the temperature of each installation area in real time. Due to differences in the control frequencies of different control units 7 within the distribution cabinet 1, control units 7 with higher control frequencies generate more heat, resulting in higher temperatures in some installation areas. When the temperature sensor detects that the temperature in some areas is too high, the airflow control device 3 immediately activates, adjusting the multiple sets of air inlets 21 on the air inlet side panel 2. Specifically, the adjustment method is to reduce the airflow to the lower-temperature installation areas while increasing the airflow to the hotter areas.

[0037] When the air inlet 21 is adjusted by the air control device 3, the partition control plate 4 is adjusted accordingly. The partition control plate 4 closes off the installation area with higher temperature to prevent the high temperature from spreading to other installation areas; at the same time, it opens the partition control plate 4 in the lower temperature area to allow airflow between the lower temperature areas. Even if the airflow in the lower temperature area is reduced, a relatively stable heat dissipation effect can be maintained.

[0038] The exhaust side panel 6 is installed on the side of the distribution cabinet 1 away from the air inlet side panel 2, and is responsible for directly exhausting the airflow from each installation area.

[0039] The power distribution cabinet 1 of the present invention can realize adaptive airflow distribution, automatically adjust the air intake volume according to the temperature of different installation areas, improve the heat dissipation effect, and reduce heat dissipation costs.

[0040] See Figures 1 to 5 As shown, the air control adjustment device 3 includes multiple adjustment frames 31 evenly distributed in the airflow channel. The side of the adjustment frame 31 is provided with multiple first air control holes 311 that match the air outlet. The side of the adjustment frame 31 is also provided with multiple pushing protrusions 312. The pushing protrusions 312 are used to push and control the partition control plate 4. A first spring 313 is installed between the adjustment frame 31 and the air inlet side plate 2. The air control adjustment device 3 also includes a pull-out adjustment device 34 that drives the multiple adjustment frames 31 to move and adjust.

[0041] Adjustable brackets 31 are evenly spaced within the airflow channel and are slidably connected to the air inlet side plate 2. Under the elastic force of the first spring 313, the adjustable brackets 31 are held in a suitable position. At this time, the pushing protrusions 312 on the side of the adjustable brackets 31 abut against the partition control plate 4, keeping the partition control plate 4 in a closed state to prevent direct airflow between different installation areas. Simultaneously, the first air control hole 311 on the side of the adjustable brackets 31 is aligned with the air inlet hole 21, with the air inlet hole 21 at its maximum diameter, ensuring that air can smoothly enter the airflow channel and be distributed to each installation area.

[0042] Temperature sensors installed on partition control plate 4 monitor the temperature of each installation area in real time. When the temperature sensor detects that the temperature of some installation areas is too high, the system determines that the air intake of that area needs to be increased to enhance heat dissipation, while the air intake of other areas with lower temperatures can be appropriately reduced.

[0043] The pull-out adjustment device 34 is activated based on the feedback signal from the temperature sensor, pulling the corresponding adjustment bracket 31 to move within the airflow channel. During the movement of the adjustment bracket 31, the first spring 313 is compressed, causing it to deform elastically. As the adjustment bracket 31 moves, the first air control hole 311 on the side of the adjustment bracket 31 misaligns with the air inlet hole 21, resulting in a reduction in the diameter of the air inlet hole 21. This reduction in the diameter of the air inlet hole 21 decreases the amount of air flowing into the corresponding installation area through it, thereby reducing the amount of air entering the lower-temperature installation area.

[0044] As the adjusting bracket 31 moves, the side pushing protrusion 312 also moves accordingly. When the adjusting bracket 31 is pulled out for adjustment, the pushing protrusion 312 disengages from the partition control plate 4, and the partition control plate 4 loses the resisting effect of the pushing protrusion 312. The partition control plate 4 then opens, allowing air to circulate between multiple lower-temperature installation areas. Even if the air intake in these areas is reduced, a relatively stable heat dissipation effect can be maintained through the air circulation between areas. For higher-temperature installation areas, the corresponding partition control plate 4 remains closed to prevent high temperature from spreading to other installation areas. At the same time, the adjusting bracket 31 in the higher-temperature installation area is not pulled out, and the first air control hole 311 is aligned with the air intake hole 21, ensuring a larger air intake to enhance heat dissipation.

[0045] When the temperature in each installation area tends to balance or reaches the set range, the pull-out adjustment device 34 stops working, and the adjustment bracket 31 resets under the elastic force of the first spring 313. After the adjustment bracket 31 resets, the first air control hole 311 realigns with the air inlet hole 21, restoring the maximum aperture of the air inlet hole 21 and increasing the air intake in the lower temperature area; at the same time, the push protrusion 312 again contacts the partition control plate 4, causing it to return to a closed state and restoring independent air circulation in each installation area inside the distribution cabinet 1.

[0046] The air conditioning device 3 can precisely control the air intake volume of the air inlet 21 and the opening and closing state of the partition control plate 4 according to the temperature of different installation areas, so as to realize the adaptive distribution of airflow, improve the heat dissipation effect of the power distribution cabinet 1, and reduce heat dissipation costs.

[0047] See Figures 3 to 6 As shown, an airflow guide plate 32 is rotatably mounted on the adjustment frame 31. The side of the airflow guide plate 32 is provided with multiple guide slopes 321. A rotation control component 33 is also installed on the side of the airflow guide plate 32.

[0048] The airflow guide plate 32 is rotatably mounted on the adjusting frame 31. When the adjusting frame 31 is not pulled by an external force, the rotation control component 33 functions to tilt the airflow guide plate 32. At this time, the air inlet device 5 delivers external airflow to the airflow channel, where the airflow rises. The rising airflow comes into contact with the tilted airflow guide plate 32, which, utilizing its tilted surface characteristics, guides the rising airflow to the first air control hole 311 on the adjusting frame 31.

[0049] Multiple guiding slopes 321 provided on the side of the airflow guide plate 32 further optimize the airflow guiding effect. The guiding slopes 321 can diffuse the guided airflow, forming diffusion streamlines, so that it passes more evenly through the first air control hole 311 and the air inlet hole 21 aligned with it, and enters each installation area of ​​the power distribution cabinet 1, ensuring that the airflow can be effectively distributed to the target area and improving the uniformity of heat dissipation.

[0050] When the temperature sensor detects an abnormal temperature in a portion of the installation area, the pull-out adjustment device 34 moves the adjustment bracket 31 within the airflow channel. This change in position triggers the response mechanism of the rotation control component 33. The rotation control component 33 then changes the airflow guide plate 32 from an inclined state to a vertical position.

[0051] When the airflow guide plate 32 is in a vertical position, its surface is perpendicular to the upward direction of the airflow, and it cannot effectively guide the upward airflow. The airflow cannot be directed to the first air control hole 311 and the air inlet hole 21. At this time, the flow path of the airflow in the airflow channel changes. It no longer enters the power distribution cabinet 1 according to the initial guidance direction, but flows according to other structures of the airflow channel or the characteristics of the airflow itself. This change in state, in conjunction with the air control adjustment device 3's regulation of the air intake volume, reduces the air intake volume in the lower temperature area, preventing excessive airflow from entering that area, while providing support for heat dissipation adjustment in other areas.

[0052] The airflow guide plate 32 can automatically adjust the airflow guidance direction according to the movement state of the adjustment frame 31, and work together with the air control adjustment device 3 to achieve precise control of the airflow distribution inside the distribution cabinet 1, improve the heat dissipation effect, and adapt to the temperature change requirements of different installation areas.

[0053] See Figures 6 to 7 As shown, the rotation control assembly 33 includes a connecting shaft 331 mounted on the airflow guide plate 32, and a strip-shaped sliding block 332 is provided on the connecting shaft 331. The rotation control assembly 33 also includes a guide mounting device 333 fixedly mounted on the air inlet side plate 2. The guide mounting device 333 has a vertical guide groove 3331 and an inclined guide groove 3332 inside, which are used to guide the strip-shaped sliding block 332 to adjust the angle.

[0054] When the airflow guide plate 32 is held in its initial position with the adjusting frame 31, the strip-shaped sliding block 332 is inserted into the inclined guide groove 3332 of the guide mounting fixture 333. The inclined guide groove 3332 matches the required tilt state of the airflow guide plate 32, and the position of the strip-shaped sliding block 332 within the inclined guide groove 3332 restricts the connecting shaft 331 to maintain a specific tilt angle, thereby keeping the airflow guide plate 32 in an inclined state. At this time, the airflow guide plate 32 effectively guides the rising airflow in the airflow channel, directing the airflow to the first air control hole 311 on the adjusting frame 31, thus achieving normal airflow distribution inside the distribution cabinet 1.

[0055] When the temperature sensor detects an abnormal temperature in a portion of the installation area, the pull-out adjustment device 34 pulls the adjustment frame 31 to move within the airflow channel, causing the airflow guide plate 32 to rise along with the adjustment frame 31. During this rising process, the connecting shaft 331 and the strip-shaped sliding block 332 move upwards accordingly.

[0056] As the strip-shaped sliding block 332 rises, it gradually disengages from the inclined guide groove 3332 and inserts into the vertical guide groove 3331. The vertical guide groove 3331 guides the strip-shaped sliding block 332 to rotate to a vertical position. Since the strip-shaped sliding block 332 is fixedly connected to the connecting shaft 331, and the connecting shaft 331 is connected to the airflow guide plate 32, the movement of the strip-shaped sliding block 332 within the vertical guide groove 3331 drives the connecting shaft 331 to rotate, thereby synchronously adjusting the airflow guide plate 32 to a vertical position.

[0057] When the airflow guide plate 32 is in a vertical position, its surface is perpendicular to the upward direction of the airflow, and it cannot effectively guide the upward airflow. The airflow cannot be directed to the first air control hole 311 and the air inlet hole 21, and the flow path of the airflow in the airflow channel changes. This change in state is coordinated with the air control and adjustment device 3 to regulate the air intake volume, so as to prevent excessive airflow from entering the area when reducing the air intake volume in the lower temperature area.

[0058] See Figures 3 to 11 As shown, the pull-out adjustment device 34 includes a mounting bracket 341 fixedly mounted on the air inlet side plate 2. Multiple telescopic locking teeth 342 are slidably mounted on the mounting bracket 341. A second spring 343 is installed between the telescopic locking teeth 342 and the mounting bracket 341. Multiple winding wheels 344 are also mounted on the mounting bracket 341. The multiple winding wheels 344 are all coaxially arranged. The inside of the winding wheel 344 is provided with a rotating mounting hole 3441. The inside of the rotating mounting hole 3441 is provided with multiple rotating unlocking grooves 3442. Each rotating unlocking groove 3442 is provided with a limiting hole for engaging the telescopic locking teeth 342. A connecting pull rope 346 is wound around the outside of the multiple winding wheels 344. The end of the connecting pull rope 346 away from the winding wheel 344 is connected to the adjustment frame 31. The pull-out adjustment device 34 also includes a multi-stage rotation drive device 345 for driving the winding wheels 344 to rotate and adjust.

[0059] The telescopic locking tooth 342 can be inserted into the limiting locking hole to limit and lock the winding wheel 344. Connecting ropes 346 are wound around the outer sides of multiple winding wheels 344. The end of the connecting rope 346 away from the winding wheel 344 is connected to the adjusting frame 31, and the multiple winding wheels 344 are rotatably connected to each other. Each winding wheel 344 is connected to the corresponding adjusting frame 31 via the connecting rope 346.

[0060] In the initial state, the telescopic tooth 342 is inserted into the limiting hole, the winding wheel 344 is locked and cannot rotate freely, the adjusting frame 31 is held in the appropriate position under the elastic force of the first spring 313, the first air control hole 311 is aligned with the air inlet hole 21, the air inlet hole 21 is in the maximum diameter state, the pushing protrusion 312 abuts against the partition control plate 4 to keep it in a closed state, and each installation area inside the power distribution cabinet 1 maintains independent air circulation.

[0061] When the temperature sensor installed on the partition control plate 4 detects an abnormal temperature in a certain installation area, it determines that the adjustment bracket 31 at the corresponding position needs to be moved. The movable end of the multi-segment rotary drive device 345 moves along the rotation mounting hole 3441 of the winding wheel 344 until it moves to the designated position of the winding wheel 344.

[0062] When the multi-stage rotary drive device 345 moves to the designated position, its movable end will push the telescopic tooth 342 out of the limiting hole. During this process, the telescopic tooth 342 compresses the second spring 343, causing the second spring 343 to undergo elastic deformation. As the telescopic tooth 342 exits the limiting hole, the winding wheel 344 is unlocked and loses its limiting constraint.

[0063] The multi-stage rotary drive device 345 drives the unlocked winding wheel 344 to rotate. As the winding wheel 344 rotates, the connecting rope 346 wrapped around its outer side is gradually wound up. Since one end of the connecting rope 346 is connected to the adjusting frame 31, the adjusting frame 31 is subjected to an upward pulling force as the connecting rope 346 is wound up, and moves upward in the airflow channel. During the movement of the adjusting frame 31, the first spring 313 is compressed, causing it to undergo elastic deformation. At the same time, the first air control hole 311 on the side of the adjusting frame 31 is misaligned with the air inlet hole 21, the diameter of the air inlet hole 21 is reduced, and the amount of air flowing into the corresponding installation area is reduced; the push protrusion 312 is disengaged from the partition control plate 4, the partition control plate 4 is opened, and air can circulate between multiple installation areas with lower temperatures.

[0064] When the adjusting frame 31 rises to the designated position, the movable end of the multi-stage rotary drive device 345 disengages from the winding wheel 344. At this time, the telescopic locking teeth 342 are re-inserted into the limiting locking holes under the elastic force of the second spring 343, the winding wheel 344 is re-locked and positioned, the connecting rope 346 stops winding, the adjusting frame 31 stops moving and remains in the adjusting position, realizing precise control of the air intake volume of a specific installation area.

[0065] See Figures 8 to 11 As shown, the multi-segment rotary drive device 345 includes a telescopic bushing 3451 slidably mounted in a rotary mounting hole 3441. A limiting mounting hole 3452 is provided at the axial center of the telescopic bushing 3451. A drive shaft 3454 is slidably mounted inside the limiting mounting hole 3452. A rotary driver 3455 is mounted at the end of the drive shaft 3454 away from the telescopic bushing 3451. The output end of the rotary driver 3455 is connected to the drive shaft 3454. A plurality of unlocking protrusions 3453 are provided on the outer side of the telescopic bushing 3451. The unlocking protrusions 3453 are slidably connected to the rotary unlocking groove 3442. The multi-segment rotary drive device 345 also includes a linear driver 3456 for driving the telescopic bushing 3451 to move.

[0066] In the initial state, the telescopic locking teeth 342 are inserted into the limiting locking holes, the winding wheel 344 is locked and cannot rotate freely, the adjusting bracket 31 is held in the appropriate position by the elastic force of the first spring 313, and each installation area inside the distribution cabinet 1 maintains independent air circulation. At this time, the telescopic bushing 3451 is in the initial position, the unlocking protrusion 3453 is not in contact with the telescopic locking teeth 342, and the winding wheel 344 is in the locked state.

[0067] When the temperature sensor installed on the partition control plate 4 detects an abnormal temperature in a part of the installation area and determines that the adjustment bracket 31 at the corresponding position needs to be moved, the linear driver 3456 is activated, driving the telescopic bushing 3451 to move telescopically in the rotating mounting hole 3441.

[0068] During the movement of the telescopic bushing 3451, the outer unlocking protrusion 3453 slides along the rotation unlocking groove 3442. As the telescopic bushing 3451 moves, the unlocking protrusion 3453 gradually approaches the telescopic locking tooth 342 in the rotation unlocking groove 3442 corresponding to the designated position of the take-up wheel 344. When the unlocking protrusion 3453 abuts against the telescopic locking tooth 342 at the designated position, it applies an outward force to the telescopic locking tooth 342, causing the telescopic locking tooth 342 to disengage from the limiting hole. During this process, the telescopic locking tooth 342 compresses the second spring 343, causing the second spring 343 to undergo elastic deformation, thereby unlocking the designated take-up wheel 344, freeing it from the limiting constraint, and enabling it to rotate freely.

[0069] When the designated take-up reel 344 is unlocked, the rotary driver 3455 is activated, driving the drive shaft 3454 to rotate. Since the drive shaft 3454 is slidably connected to the telescopic sleeve 3451 and the rotation of the drive shaft 3454 is transmitted to the telescopic sleeve 3451, the telescopic sleeve 3451 rotates accordingly.

[0070] When the telescopic bushing 3451 rotates, the outer unlocking protrusion 3453 engages with the unlocked winding wheel 344's rotation unlocking groove 3442, causing the unlocked winding wheel 344 to rotate synchronously. As the winding wheel 344 rotates, the connecting rope 346 wound around its outer side is gradually wound up. Since one end of the connecting rope 346 is connected to the adjusting frame 31, the adjusting frame 31 experiences an upward pulling force as the connecting rope 346 is wound up, causing it to rise and move within the airflow channel. During this movement, the adjusting frame 31 compresses the first spring 313, causing it to deform elastically. Simultaneously, the first air control hole 311 on the side of the adjusting frame 31 misaligns with the air inlet hole 21, reducing the diameter of the air inlet hole 21 and decreasing the airflow into the corresponding installation area. This causes the pushing protrusion 312 to disengage from the partition control plate 4, opening the partition control plate 4 and enabling airflow between multiple lower-temperature installation areas.

[0071] When the adjusting frame 31 rises to the designated position, the linear actuator 3456 drives the telescopic sleeve 3451 to move in the opposite direction, causing the unlocking protrusion 3453 to disengage from the telescopic locking tooth 342. At this time, under the elastic force of the second spring 343, the telescopic locking tooth 342 is re-inserted into the limiting hole, the winding wheel 344 is re-locked and positioned, the connecting rope 346 stops winding, and the adjusting frame 31 stops moving and remains in the current position, realizing precise control of the air intake volume of the installation area.

[0072] See Figure 3 and Figure 12As shown, the partition control plate 4 includes a horizontal partition plate 42, which has several ventilation holes 421. The interior of the horizontal partition plate 42 has a sliding slot, and a sealing plate 43 is slidably installed inside the sliding slot. The sealing plate 43 has a second air control hole that matches the ventilation holes 421. A third spring 41 is installed between the sealing plate 43 and the horizontal partition plate 42. A strip-shaped contact bracket 431 is provided on one side of the sealing plate 43. The strip-shaped contact bracket 431 passes through the air inlet side plate 2 and contacts the adjustment bracket 31.

[0073] A third spring 41 is installed between the sealing plate 43 and the horizontal partition plate 42. When the third spring 41 is in its natural state, the sealing plate 43 is in its initial position. A strip-shaped abutment bracket 431 is provided on one side of the sealing plate 43. The strip-shaped abutment bracket 431 passes through the air inlet side plate 2 and contacts the adjusting bracket 31.

[0074] When the adjusting bracket 31 is in its initial position, the pushing protrusion 312 on the side wall of the adjusting bracket 31 will push against the strip-shaped contact bracket 431. Under the action of the pushing force, the strip-shaped contact bracket 431 drives the sealing plate 43 to move within the sliding slot, causing the second air control hole of the sealing plate 43 to misalign with the ventilation hole 421 on the horizontal partition plate 42. At this time, the sealing plate 43 blocks the ventilation hole 421, and the flowing air cannot pass through the partition control plate 4, maintaining independent air circulation between each installation area, preventing direct airflow between different installation areas, and avoiding the diffusion of high-temperature air from high-temperature areas to other areas.

[0075] When the temperature sensor installed on the partition control plate 4 detects that the temperature in a certain installation area is low, and the air control adjustment device 3 adjusts the adjustment frame 31 in the low-temperature area, the adjustment frame 31 moves upward. As the adjustment frame 31 moves, the pushing protrusion 312 on the side of the adjustment frame 31 gradually disengages from the strip-shaped contact frame 431.

[0076] When the pushing protrusion 312 disengages from the strip-shaped abutment frame 431, the sealing plate 43 loses its pushing force. Under the elastic force of the third spring 41, the sealing plate 43 moves within the sliding slot, causing the strip-shaped abutment frame 431 to contact the plane of the adjusting frame 31. During this process, the second air control hole of the sealing plate 43 connects with the ventilation hole 421 on the horizontal partition plate 42, allowing airflow to circulate between the installation areas through the ventilation hole 421 and the second air control hole. In this way, even if the air intake in the lower temperature area is reduced due to the movement of the adjusting frame 31, a relatively stable heat dissipation effect can be maintained through air circulation between areas, ensuring the stability and uniformity of heat dissipation in the lower temperature area.

[0077] See Figures 1 to 3 As shown, the air inlet device 5 includes an inclined mounting bracket 51, the air outlet end of the inclined mounting bracket 51 is inclined, multiple fans 52 are mounted on the inclined mounting bracket 51, and the air outlet end of the inclined mounting bracket 51 is connected to the airflow channel.

[0078] The air outlet of the mounting bracket is set at an angle, and the air outlet is connected to the airflow channel inside the air inlet side plate 2. The angled setting can optimize the angle and path of airflow entering the airflow channel, effectively improve the smoothness of airflow entering the airflow channel, reduce airflow resistance, and ensure that air can smoothly enter the airflow channel.

[0079] The air inlet end of the inclined mounting bracket 51 is equipped with a dustproof net. The dustproof net can filter dust, particulate matter and other impurities in the air entering the air inlet device 5, prevent dust from entering the inside of the distribution cabinet 1 and avoid dust from damaging the control unit inside the distribution cabinet 1.

[0080] Multiple fans 52 are mounted on the inclined mounting bracket 51. The number of fans 52 that can be activated can be controlled according to the temperature inside the distribution cabinet 1. Temperature sensors monitor the temperature of each installation area inside the distribution cabinet 1 in real time and feed the temperature data back to the control system. When the temperature inside the distribution cabinet 1 is low, the control system only activates some of the fans 52 to provide airflow to meet basic heat dissipation needs, thereby reducing energy consumption and effectively reducing heat dissipation costs.

[0081] When the temperature sensor detects an increase in temperature in a certain installation area inside the distribution cabinet 1, requiring increased airflow to enhance heat dissipation, the control system will gradually increase the number of fans 52 activated based on the degree and range of temperature increase. With more fans 52 activated, a larger airflow is generated, delivering more external air through the inclined mounting bracket 51 to the airflow channel, and then through the air inlet 21 into each installation area, carrying away heat from the installation area and reducing the temperature of the control unit 7.

[0082] See Figure 3 As shown, the side of the air outlet panel 6 is provided with multiple sets of air outlet holes 61, and each set of air outlets is connected to the corresponding installation area.

[0083] During the daily operation of the distribution cabinet 1, the air intake device 5 delivers outside air to the airflow channel, which guides the air to various installation areas through multiple sets of air inlets 21. As the air passes through the installation areas, it carries away the heat generated by the control units within those areas, forming hot air.

[0084] The hot air accumulates within the installation area, creating a pressure difference. Since the air outlet 61 on the exhaust side panel 6 is directly connected to the installation area, the hot air is discharged from the distribution cabinet 1 through the air outlet 61. The multiple sets of air outlets 61 ensure that the hot air from each installation area can be discharged independently, effectively preventing mutual interference and backflow between different installation areas. For example, hot air generated in a higher-temperature installation area will not flow back to a lower-temperature installation area due to airflow turbulence, thus ensuring that the heat dissipation effect of each installation area is not affected by other areas.

[0085] Specific working principle:

[0086] During normal operation of the distribution cabinet 1, the air intake device 5 is activated, delivering outside air to the airflow channel. The airflow channel guides the air to various installation areas through multiple sets of air inlets 21. Each set of air inlets 21 has multiple guide vanes 22 installed at its outlet end to evenly diffuse the airflow and ensure that air enters the installation area uniformly. As the air passes through the installation area, it carries away heat from the installation area, reducing the temperature of the control unit 7.

[0087] Temperature sensors monitor the temperature of each installation area in real time. Due to differences in the control frequencies of different control units 7 within the distribution cabinet 1, control units 7 with higher control frequencies generate more heat, resulting in higher temperatures in some installation areas. When the temperature sensor detects that the temperature in some areas is too high, the airflow control device 3 immediately activates, adjusting the multiple sets of air inlets 21 on the air inlet side panel 2. Specifically, the adjustment method is to reduce the airflow to the lower-temperature installation areas while increasing the airflow to the hotter areas.

[0088] When the air inlet 21 is adjusted by the air control device 3, the partition control plate 4 is adjusted accordingly. The partition control plate 4 closes the high-temperature installation area to prevent the high temperature from spreading to other installation areas; at the same time, it opens the partition control plate 4 in the low-temperature area, allowing airflow between the low-temperature areas. Even if the airflow in the low-temperature area is reduced, a relatively stable heat dissipation effect can be maintained. The exhaust side plate 6 is installed on the side of the distribution cabinet 1 away from the air inlet side plate 2, and is responsible for directly exhausting the airflow from each installation area. The distribution cabinet 1 of the present invention can realize adaptive airflow distribution, automatically adjust the air intake according to the temperature of different installation areas, improve the heat dissipation effect, and reduce heat dissipation costs.

[0089] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
