Description

Technical Field

[0001] This invention belongs to the field of distribution box protection technology, specifically a comprehensive distribution box device with high-efficiency heat dissipation. Background Technology

[0002] Integrated distribution boxes are electrical equipment used for power distribution, control, and protection. They are applied in various power structures, industrial production, and civil applications. Their function is to integrate and protect power distribution devices, achieving rational power distribution while ensuring the long-term stable operation of internal components and preventing issues such as overheating and corrosion from impurities from affecting power supply safety and reliability. With the advancement of new power structure construction, the load on power distribution devices is constantly increasing, placing higher demands on the heat dissipation efficiency and operational stability of integrated distribution boxes. Current technologies still have the following technical problems: First, the existing integrated distribution boxes cannot achieve synchronous linkage between the power distribution components and the heat dissipation equipment. After the power distribution components are installed and fixed, manual wiring and equipment start-up operations are required. The heat dissipation equipment cannot work synchronously with the power distribution components when they are started, which can easily lead to heat accumulation in the early stage of power distribution component startup, affecting the service life of the components. In addition, manual operation increases maintenance costs and the probability of operational errors.

[0003] Secondly, the existing integrated distribution boxes lack purification measures for heat dissipation airflow. The airflow they draw in contains a large number of impurities, which can easily cause blockage of heat dissipation pipes and damage to heat dissipation power equipment. This results in the heat dissipation structure being unable to operate continuously and stably, thus affecting the overall heat dissipation effect and failing to provide stable heat dissipation for power distribution devices.

[0004] Furthermore, the airflow pressure and flow rate of the existing integrated distribution box cannot be adjusted. When the working power of the cooling power equipment is adjusted, the airflow pressure and flow rate are prone to fluctuation. Either the pressure is too high and will impact the power distribution device, or the pressure is too low and will result in insufficient heat dissipation. It is difficult to adapt to the heat dissipation requirements of the power distribution device under different loads, and the heat dissipation stability and efficiency are poor. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides an integrated power distribution box device with efficient heat dissipation, so as to at least partially solve the above technical problems.

[0006] The technical solution adopted in this invention is as follows: This invention proposes a comprehensive power distribution box device with high-efficiency heat dissipation, comprising: An external protective box is provided, the interior of which is a working chamber, the interior of which is a partition plate, and an air exchange pump is located below the partition plate; A load-bearing limiting plate is provided above the partition plate. A power distribution device is provided inside the load-bearing limiting plate. A power distribution device control module and an air exchange pump control module are provided at the center of the inner wall of the partition plate. The power distribution device control module is electrically connected to the power distribution device through a conductor wire, and the air exchange pump control module is electrically connected to the air exchange pump through a conductor wire.

[0007] In one embodiment of the present invention, buffer damping rods are provided at the four corners of the bottom surface of the bearing limiting plate, the bottom end of the buffer damping rods is provided on the top surface of the inner wall of the partition plate, positive magnetic plates are provided on both sides of the bottom surface of the bearing limiting plate, and negative magnetic plates are provided on the corresponding sides of the top surface of the inner wall of the partition plate.

[0008] In one embodiment of the present invention, a limiting hole is provided on the outer wall of the external protective box, and an air collecting plate is embedded inside the limiting hole. Several sets of airflow guide holes are provided on the outer wall of one side of the air collecting plate. The airflow guide holes are arranged facing the working chamber, and a filter plate is provided inside the airflow guide holes.

[0009] In one embodiment of the present invention, the working end of the air exchange pump is connected to an airflow delivery pipe, the other end of the airflow delivery pipe extends to the outside of the external protective box and is connected to the inside of the air collection plate. The airflow delivery pipe is divided into a transverse segment and a longitudinal segment. The interior of the transverse segment is provided with two sets of impurity adsorption plates, and an adsorption rod is provided between the two sets of impurity adsorption plates. The outer wall of the adsorption rod is provided with several sets of L-shaped filter rods.

[0010] In one embodiment of the present invention, the interior of the longitudinal segment is provided with two sets of filter screens, the outer walls of the two sets of filter screens are respectively provided with bearing seats, a guide rod is provided between the two bearing seats, the outer wall of the guide rod is provided with a threaded sleeve, and the outer wall of the threaded sleeve is axially arrayed with a plurality of airflow regulating blades.

[0011] In one embodiment of the present invention, tension damping rods are respectively provided on the outer walls of the upper and lower sides of the threaded sleeve, and the other end of the tension damping rods is respectively provided on the outer wall of the bearing seat.

[0012] In one embodiment of the present invention, the surface of the external protective box is provided with an inspection door, and the outer wall of the inspection door is provided with a control panel. The control panel is electrically connected to the power distribution device and the air exchange pump respectively through conductive lines.

[0013] In one embodiment of the present invention, a plurality of first heat dissipation holes are formed on the surface of the inspection door, and a plurality of second heat dissipation holes are formed on the lower part of the outer walls on both sides of the external protective box. The plurality of second heat dissipation holes are symmetrically distributed on the outer walls on both sides of the external protective box. The plurality of second heat dissipation holes are located on both sides of the air exchange pump. The second heat dissipation holes penetrate the side wall of the external protective box and are connected to the interior of the working chamber.

[0014] The beneficial effects of the technical solution of this invention are as follows: This invention uses the mutual attraction between the positive and negative magnetic plates to fix the load-bearing limiting plate and the partition plate. After the power distribution device is installed in place, the bottom of the load-bearing limiting plate contacts the power distribution device control module and the air exchange pump control module, triggering the two control modules to start synchronously, realizing the synchronous operation of the power distribution device and the air exchange pump, avoiding heat accumulation when the power distribution device starts, and realizing automatic linkage of automatic power supply and heat dissipation of the power distribution device, without the need for manual wiring or manual start of the equipment.

[0015] This invention optimizes the stability and efficiency of heat dissipation through the cooperation of the airflow delivery pipe and its internal components, under the regulation of the power distribution device control module and the air exchange pump control module. The airflow delivery pipe is divided into horizontal and vertical sections. The two sets of impurity adsorption plates and adsorption rods and L-shaped filter rods inside the horizontal section work together to initially purify the airflow drawn into the air exchange pump, intercepting most of the larger and smaller impurities. The two sets of filter screens inside the vertical section achieve secondary purification, further improving the cleanliness of the airflow, preventing impurities from clogging the airflow delivery pipe and damaging the air exchange pump, ensuring the stable operation of the air exchange pump, and providing continuous power for heat dissipation.

[0016] This invention utilizes the cooperation of guide rods, threaded sleeves, airflow regulating vanes, and tension damping rods within the longitudinal segments to regulate airflow pressure and flow rate. When the air exchange pump adjusts its operating power under the control module, the airflow pressure changes. The airflow acts on the airflow regulating vanes, causing the threaded sleeve to move up and down along the guide rod. The tension damping rod generates damping resistance, limiting the movement speed of the threaded sleeve, thereby regulating the airflow flow rate and pressure. This ensures that the airflow is stably and evenly delivered to the air collecting plate and then blown onto the power distribution components, preventing excessive airflow pressure from impacting the power distribution components or insufficient airflow pressure from causing inadequate heat dissipation.

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] The following description, with reference to the accompanying drawings, describes an embodiment of the present invention of a comprehensive power distribution box device with efficient heat dissipation.

[0022] like Figures 1 to 12As shown, this embodiment of the invention provides a comprehensive power distribution box device with high-efficiency heat dissipation, including: an external protection box 1, an internal working chamber 6, a partition plate 7 inside the working chamber 6, and an air exchange pump 17 below the partition plate 7. A load-bearing limiting plate 11 is provided above the partition plate 7. A power distribution device 12 is provided inside the load-bearing limiting plate 11. A power distribution device control module 28 and an air exchange pump control module 29 are provided at the center of the inner wall of the partition plate 7. The power distribution device control module 28 is electrically connected to the power distribution device 12 through a conductor line, and the air exchange pump control module 29 is electrically connected to the air exchange pump 17 through a conductor line.

[0023] In a specific application of this invention, the external protective box 1 physically isolates the internal space of the box in the vertical direction by setting a partition plate 7 inside the working chamber 6. An air exchange pump 17 is arranged below the partition plate 7, and a load-bearing limiting plate 11 is arranged above it. The load-bearing limiting plate 11 houses the power distribution device 12. The center of the inner wall of the partition plate 7 is respectively embedded with the power distribution device control module 28 and the air exchange pump control module 29. The two control modules establish an electrical connection relationship with the corresponding execution components through a conduction line, that is, the power distribution device control module 28 is directly connected to the power distribution device 12, and the air exchange pump control module 29 is directly connected to the air exchange pump 17.

[0024] Furthermore, when the power distribution device 12 is installed on the bearing limiting plate 11, gravity causes the bearing limiting plate 11 to move downward until the positive magnetic plate 9 and the negative magnetic plate 10 come into contact and generate magnetic attraction. At this time, the bottom plane of the bearing limiting plate 11 and the control module contact surface on the partition plate 7 are tightly fitted. The power distribution device control module 28 then sends a working command to the power distribution device 12, and at the same time, the air exchange pump control module 29 starts the air exchange pump 17.

[0025] Specifically, after the air exchange pump 17 starts, its working end begins to draw in airflow. The airflow first enters through the second heat dissipation hole 4 located below the outer walls on both sides of the external protective box 1. The heat dissipation holes are distributed on both sides of the air exchange pump 17. The drawn-in airflow first undergoes pretreatment through the airflow delivery pipe 18, which is divided into a transverse section 30 and a longitudinal section 31. The airflow first enters the transverse section 30. Inside the section, the airflow passes sequentially through two sets of impurity adsorption plates 19, adsorption rods 20, and L-shaped filter rods 21. The impurity adsorption plates 19 and L-shaped filter rods 21 work together to remove dust and fibrous solid particles carried in the airflow by means of physical interception and surface adsorption.

[0026] Specifically, after initial purification in the transverse segment 30, the airflow enters the longitudinal segment 31. The longitudinal segment 31 contains two sets of filter screens 22 to further intercept fine particles. Bearing seats 24 are installed on the opposite outer walls of the filter screens 22, and a guide rod 23 is positioned between the two bearing seats 24. A threaded sleeve 25 is fitted onto the guide rod 23. Several sets of airflow regulating vanes 27 are axially arrayed on the outer wall of the threaded sleeve 25. When the airflow flows through the longitudinal segment 31 under the suction force of the air exchange pump 17, the kinetic energy of the airflow acts on the airflow regulating vanes 27, pushing the threaded sleeve 25 upwards along the guide rod 23. A tension damping rod 26 connects the threaded sleeve 25 and the bearing seats 24, providing resistance to the movement of the threaded sleeve 25. As the threaded sleeve 25 moves upwards, the opening of the airflow regulating vanes 27 within the airflow channel changes, thereby dynamically adjusting the airflow cross-section and pressure.

[0027] Furthermore, the regulated and stable airflow is finally delivered to the interior of the air collecting plate 14. The air collecting plate 14 is located in the limiting hole 13 on the outer wall of the external protective box 1. Several sets of airflow guide holes 15 are opened on the side facing the working chamber 6. The guide holes are equipped with filter plates 16. After the airflow passes through the airflow guide holes 15 and the filter plates 16, it blows towards the power distribution device 12 inside the working chamber 6 at a controlled speed and direction. Since the bearing limiting plate 11 is located above the partition plate 7 and the power distribution device 12 is placed inside the bearing limiting plate 11, the airflow can directly cover the surface of the power distribution device 12 and the surrounding space, carrying away heat.

[0028] In one specific embodiment, buffer damping rods 8 are provided at the four corners of the bottom surface of the bearing limiting plate 11, and the bottom end of the buffer damping rods 8 is provided on the top surface of the inner wall of the partition plate 7. Positive magnetic plates 9 are provided on both sides of the bottom surface of the bearing limiting plate 11, and negative magnetic plates 10 are provided on the corresponding sides of the top surface of the inner wall of the partition plate 7.

[0029] In specific applications of this invention, buffer damping rods 8 are fixedly installed at the four corners of the bottom surface of the bearing limiting plate 11. The four sets of buffer damping rods 8 are symmetrically distributed. The top of each set of buffer damping rods 8 is fixedly connected to the four corners of the bottom surface of the bearing limiting plate 11, and the bottom of each set of buffer damping rods 8 is fixedly connected to the top of the inner wall of the partition plate 7. The four sets of buffer damping rods 8 have the same length and perpendicular axis, forming a stable support structure with the bearing limiting plate 11 and the partition plate 7. The buffer damping rods 8 are made of elastic damping material and have the characteristics of being stretchable and buffering. Their placement corresponds to the four corners of the bearing limiting plate 11, which can evenly distribute the weight of the bearing limiting plate 11 and the power distribution device 12, so that the bearing limiting plate 11 is subjected to balanced force, avoiding deformation and damage of the bearing limiting plate 11 due to excessive local force, and providing elastic support for the bearing limiting plate 11 to alleviate the vibration generated during the operation of the device.

[0030] Furthermore, positive magnetic plates 9 are fixedly installed on both sides of the bottom surface of the bearing limiting plate 11. The two sets of positive magnetic plates 9 are symmetrically distributed and fit against the bottom surface of the bearing limiting plate 11. They are also embedded to ensure that the positive magnetic plates 9 will not shift due to vibration or airflow impact. On the top surface of the inner wall of the partition plate 7, corresponding to the two sides of the positive magnetic plates 9, negative magnetic plates 10 are fixedly installed. The two sets of negative magnetic plates 10 correspond to the two sets of positive magnetic plates 9, and their installation height is flush with that of the positive magnetic plates 9 to ensure that they can be attracted to each other. Both the positive magnetic plates 9 and the negative magnetic plates 10 are made of high-strength permanent magnet material and have stable magnetic attraction capabilities. Their attraction strength is reasonably set so that they can not only fix the bearing limiting plate 11 and the partition plate 7, but also be easily separated by external force when disassembly and maintenance are required.

[0031] Specifically, after the load-bearing limit plate 11 carries the power distribution device 12, its own weight and the weight of the power distribution device 12 will be transmitted to the partition plate 7 through the buffer damping rods 8 at the four corners. The buffer damping rods 8 absorb the vibration generated during the operation of the device through their own elastic expansion and contraction characteristics, including the vibration generated when the air exchange pump 17 is working, the vibration transmitted from the external environment, and the slight vibration generated when the power distribution device 12 is working, so as to avoid the vibration being transmitted to the power distribution device 12, prevent the power distribution device 12 from having loose wiring and component damage due to long-term vibration, and at the same time reduce the interference of vibration on the signal transmission of the power distribution device control module 28 and the air exchange pump control module 29, and ensure the working stability of each component.

[0032] Specifically, the adsorption effect of the positive magnetic plate 9 and the negative magnetic plate 10 enables the positioning and fixation between the bearing limiting plate 11 and the partition plate 7. After the power distribution device 12 is installed inside the bearing limiting plate 11, the bearing limiting plate 11 moves downward under its own weight and the weight of the power distribution device 12, causing the positive magnetic plate 9 on the bottom surface to approach the negative magnetic plate 10 on the top surface of the partition plate 7 until the two are attracted to each other, thus fixing the bearing limiting plate 11 and protecting the bearing limiting plate 11 and the partition plate 7 from damage. When the power distribution device 12 is subsequently inspected or replaced, only external force needs to be applied to separate the positive magnetic plate 9 and the negative magnetic plate 10, and the bearing limiting plate 11 and the power distribution device 12 can be easily removed without disassembling other parts, thus improving the convenience of maintenance.

[0033] Meanwhile, the buffer damping rod 8 acts as a buffer and guide during the adsorption and fixation of the positive magnetic plate 9 and the negative magnetic plate 10, preventing the bearing limiting plate 11 from moving downward too quickly, which could cause the positive magnetic plate 9 and the negative magnetic plate 10 to collide violently, damaging the magnetic plate structure or affecting the adsorption effect. At the same time, through its own elastic support, the positive magnetic plate 9 and the negative magnetic plate 10 can be adsorbed smoothly, ensuring that the bearing limiting plate 11 is in a horizontal state after being fixed, preventing the power distribution device 12 from shifting or shaking due to the tilt of the bearing limiting plate 11. The elastic characteristics of the buffer damping rod 8 can also continuously provide upward support after the positive magnetic plate 9 and the negative magnetic plate 10 are adsorbed, which, together with the magnetic adsorption force, further improves the fixing stability of the bearing limiting plate 11, preventing the bearing limiting plate 11 from loosening or shifting due to vibration and airflow impact, and ensuring that the power distribution device 12 is always in a stable working position.

[0034] In one specific embodiment, a limiting hole 13 is opened on the outer wall of the external protective box 1, and an air collecting plate 14 is embedded inside the limiting hole 13. Several sets of airflow guide holes 15 are opened on the outer wall of one side of the air collecting plate 14. The airflow guide holes 15 are arranged facing the working chamber 6, and a filter plate 16 is provided inside the airflow guide holes 15.

[0035] In a specific application of this invention, the outer wall of the external protective box 1 has a limiting hole 13 that penetrates the wall thickness of the box to form a channel for airflow in and out. An air collecting plate 14 is embedded inside the limiting hole 13. The air collecting plate 14 fits tightly with the inner wall of the limiting hole 13 to prevent airflow from leaking from the edge. Several sets of airflow guide holes 15 are opened on the outer wall of the side of the air collecting plate 14 facing the working chamber 6. The airflow guide holes 15 are arranged in an array and the opening direction is directly facing the internal space of the working chamber 6. A filter plate 16 is installed inside each airflow guide hole 15. The filter plate 16 covers the channel of the airflow guide hole 15 to block external impurities from entering.

[0036] Furthermore, when the airflow enters from outside the external protective box 1, it passes through the airflow delivery pipe 18 and reaches the surface of the air collecting plate 14. The air collecting plate 14 initially gathers and distributes the airflow from the airflow delivery pipe 18, allowing the airflow to flow evenly to each airflow guide hole 15. When the airflow passes through the airflow guide hole 15, it is intercepted by the filter plate 16. Dust and fibrous solid particles in the air are captured or blocked by the surface of the filter plate 16, and only clean air continues to flow forward, ensuring that the air entering the working chamber 6 meets the required cleanliness standard.

[0037] Furthermore, several sets of airflow guide holes 15 are symmetrically arranged around the center of the air collecting plate 14, so that the airflow can blow onto the power distribution device 12 from multiple angles. The multi-directional airflow distribution avoids local overcooling or dead zones caused by single-point airflow, improves heat dissipation efficiency, ensures sufficient ventilation, and maintains an appropriate airflow speed to avoid mechanical damage to the power distribution device 12 caused by high-speed airflow. The filter plate 16 is installed inside the airflow guide holes 15. Its material is selected as a porous material with high porosity and low resistance to reduce airflow resistance while ensuring filtration effect. The filter plate 16 is sealed to the inner wall of the airflow guide holes 15 to prevent unfiltered air from seeping in through the gaps. When the airflow passes through the filter plate 16, the flow velocity changes slightly, and some kinetic energy is converted into heat energy, which helps to increase the temperature of the air entering the working chamber 6.

[0038] Specifically, after the high-pressure airflow output from the airflow delivery pipe 18 enters the air collecting plate 14, the pressure is released, the flow rate decreases, and the static pressure increases. The cavity inside the air collecting plate 14 plays a stabilizing role, making the airflow distribution in each airflow guide hole 15 more uniform. A sealing gasket is provided between the outer wall of the air collecting plate 14 and the limiting hole 13 of the external protective box 1 to prevent external dust from entering the box from the installation gap. The power distribution device 12 is located on the bearing limiting plate 11, which is located above the partition plate 7. Therefore, after the airflow flows out from the air collecting plate 14, it blows vertically downward or obliquely towards the surface of the power distribution device 12. After the airflow contacts the surface of the power distribution device 12, it carries away heat and then forms a circulation in the working chamber 6, and finally is discharged from the first heat dissipation hole 3 or the second heat dissipation hole 4.

[0039] In one specific embodiment, the working end of the air exchange pump 17 is connected to an airflow delivery pipe 18, and the other end of the airflow delivery pipe 18 extends to the outside of the external protective box 1 and is connected to the inside of the air collection plate 14. The airflow delivery pipe 18 is divided into a transverse segment 30 and a longitudinal segment 31. The interior of the transverse segment 30 is provided with two sets of impurity adsorption plates 19, and an adsorption rod 20 is provided between the two sets of impurity adsorption plates 19. The outer wall of the adsorption rod 20 is provided with several sets of L-shaped filter rods 21.

[0040] The longitudinal segment 31 has two sets of filter screens 22 inside. The outer walls of the two sets of filter screens 22 are respectively provided with bearing seats 24. A guide rod 23 is provided between the two bearing seats 24. The outer wall of the guide rod 23 is provided with a threaded sleeve 25. The outer wall of the threaded sleeve 25 is axially arranged with several sets of airflow regulating blades 27. The outer walls of the upper and lower sides of the threaded sleeve 25 are respectively provided with tension damping rods 26. The other end of the tension damping rods 26 is respectively provided on the outer wall of the bearing seat 24.

[0041] In a specific application of this invention, the working end of the air exchange pump 17 is directly connected to the airflow delivery pipe 18. The other end of the airflow delivery pipe 18 extends to the external space of the external protective box 1 and is inserted into the internal channel of the air collecting plate 14. Structurally, the airflow delivery pipe 18 is divided into two parts: a transverse segment 30 and a longitudinal segment 31. The two segments are connected at right angles or a specific angle in space to form a complete airflow transmission path. The transverse segment 30 is located on the side closest to the air exchange pump 17. Inside it, two sets of impurity adsorption plates 19 are arranged sequentially along the airflow direction. A gap is left between the two sets of impurity adsorption plates 19, and an adsorption rod 20 is installed at the center of the gap. Several sets of L-shaped filter rods 21 are evenly distributed on the outer wall surface of the adsorption rod 20. The L-shaped filter rods 21 extend outward from the adsorption rod 20 to form a complex three-dimensional interception net. When the airflow passes through the transverse segment 30, it first contacts the first set of impurity adsorption plates 19, and larger particles are blocked or adsorbed. The airflow then passes through the area formed by the adsorption rod 20 and the L-shaped filter rod 21. The L-shaped structure increases the turbulence and contact area of ​​the airflow, making it easier for fine particles and fibrous impurities to adhere to the surface of the L-shaped filter rod 21 or remain around the adsorption rod 20. The gap between the two sets of impurity adsorption plates 19 allows airflow to pass through, but the adsorption rod 20 and the L-shaped filter rod 21 prolong the residence time of impurities in the airflow, improving the capture efficiency.

[0042] Furthermore, after leaving the transverse segment 30, the airflow enters the longitudinal segment 31. The longitudinal segment 31 is internally equipped with two sets of filter screens 22, arranged in parallel. Bearing seats 24 are fixed to the opposite outer walls of each set of filter screens. A guide rod 23 is mounted between the two bearing seats 24, extending through the entire length of the longitudinal segment 31. A threaded sleeve 25 is fitted onto the outer wall of the guide rod 23, allowing it to slide axially along the guide rod 23. Several sets of airflow regulating blades 27 are arranged in an axial array on the outer wall of the threaded sleeve 25. The blades of the airflow regulating blades 27 are arranged spirally or radially, and their angles change with the rotation or movement of the threaded sleeve 25. When the airflow flows through the longitudinal segment 31 under the suction force of the air exchange pump 17, the airflow impacts the airflow regulating blades 27, generating thrust. This thrust acts on the threaded sleeve 25, causing it to overcome resistance and move upwards along the guide rod 23. The tension damping rod 26 is installed on the upper and lower outer walls of the threaded sleeve 25. The other end of the tension damping rod 26 is fixed on the outer wall of the bearing seat 24. The tension damping rod 26 provides reverse tension or resistance during the movement of the threaded sleeve 25, limiting the movement speed of the threaded sleeve 25 and preventing it from displacing too quickly due to airflow fluctuations.

[0043] Furthermore, as the threaded sleeve 25 moves upward, the relative position of the airflow regulating vane 27 within the longitudinal segment 31 changes, thereby altering the effective cross-sectional area of ​​the airflow channel. When the airflow pressure output by the air exchange pump 17 increases, the threaded sleeve 25 moves upward, increasing the stretch of the damping rod 26 and consequently increasing the damping resistance. This slows down the movement speed of the threaded sleeve 25, preventing excessive airflow pressure from damaging the air collecting plate 14 and the airflow guide hole 15. Simultaneously, it regulates the airflow flow rate to prevent excessively high local airflow pressure from affecting the heat dissipation effect. When the airflow pressure decreases, the rebound force of the damping rod 26 causes the threaded sleeve 25 to return to its original position downward, maintaining the angle of the airflow regulating vane 27 and ensuring a stable airflow output. This prevents insufficient heat dissipation due to low airflow pressure. The two sets of filter screens 22 further intercept the tiny particles remaining after passing through the transverse segment 30, ensuring a high degree of cleanliness in the airflow entering the air collecting plate 14. The bearing seat 24 provides stable support for the sliding of the threaded sleeve 25, ensuring that the threaded sleeve 25 does not become skewed or stuck during movement.

[0044] Specifically, the combination of the transverse segment 30 and the longitudinal segment 31 constitutes a multi-stage filtration and adaptive adjustment assembly. After the airflow exits from the air exchange pump 17, it first passes through the physical interception of the transverse segment 30 to remove most of the visible impurities. Then it enters the longitudinal segment 31 and is filtered by the filter screen 22. At the same time, the airflow regulating vane 27 automatically adjusts its opening according to the real-time pressure, ensuring the purity and stability of the airflow through staged processing.

[0045] In one specific embodiment, a number of first heat dissipation holes 3 are opened on the surface of the inspection door 2, and a number of second heat dissipation holes 4 are opened on the lower side of the outer walls on both sides of the external protective box 1. The number of second heat dissipation holes 4 are symmetrically distributed on the outer walls on both sides of the external protective box 1. The number of second heat dissipation holes 4 are located on both sides of the air exchange pump 17. The second heat dissipation holes 4 penetrate the side wall of the external protective box 1 and are connected to the interior of the working chamber 6.

[0046] In a specific application of this invention, several sets of first heat dissipation holes 3 are opened on the surface of the inspection door 2. The first heat dissipation holes 3 connect the inside of the working chamber 6 with the external environment. When the air exchange pump 17 is started to perform forced ventilation, the hot air in the working chamber 6 diffuses to the surroundings under the action of negative pressure, and part of the airflow is discharged through the first heat dissipation holes 3 on the inspection door 2. At the same time, the first heat dissipation holes 3 increase the number of exhaust channels in the working chamber 6, reduce the overall exhaust resistance, and allow the hot air to leave the inside of the box more smoothly. Several sets of second heat dissipation holes 4 are opened on the lower part of the outer walls on both sides of the external protective box 1. The second heat dissipation holes 4 are symmetrically distributed on the outer walls on both sides of the external protective box 1 to ensure that the airflow exchange capacity on both sides of the box is consistent, and to prevent uneven heating or structural deformation of the box due to heat dissipation on one side.

[0047] Furthermore, several sets of second heat dissipation holes 4 are located on both sides of the air exchange pump 17. When the air exchange pump 17 is running, its suction effect reduces the air pressure inside the working chamber 6, and the external air naturally flows to the low-pressure area under the pressure difference. Since the second heat dissipation holes 4 are located outside the air exchange pump 17 and at the bottom of the housing, the cold air has a higher density and can easily enter from the bottom opening. Fresh external air is drawn into the working chamber 6 through the second heat dissipation holes 4, replenishing the discharged hot air and forming a continuous airflow circulation.

[0048] Furthermore, the second heat dissipation hole 4 penetrates the side wall of the external protective box 1 and is connected to the interior of the working chamber 6, ensuring that the air intake can meet the air pumping requirements of the air exchange pump 17, avoiding the air exchange pump 17 from running inefficiently or generating noise due to insufficient air intake. The symmetrically distributed second heat dissipation holes 4 allow airflow to enter evenly from both sides of the box, avoiding airflow vortices or dead corners caused by single-sided air intake, and improving the uniformity of airflow organization in the working chamber 6.

[0049] Specifically, when the power distribution device 12 operates within the working chamber 6, it generates a large amount of heat, heating the surrounding air. The hot air rises and accumulates at the top of the working chamber 6. At this time, the air exchange pump 17 starts, extracting the hot air from the top, causing a drop in air pressure within the working chamber 6. External cold air then rushes in through the second heat dissipation hole 4 at the bottom, filling the vacuum area. The cold air flows over the surface of the power distribution device 12, absorbs heat, and its temperature rises. It is then extracted again by the air exchange pump 17, forming a convection cycle. The first heat dissipation hole 3 on the inspection door 2 serves as an auxiliary exhaust port, further accelerating the hot air exhaust process and preventing the temperature inside the working chamber 6 from becoming too high.

[0050] In one specific embodiment, the surface of the external protection box 1 is provided with an inspection door 2, and the outer wall of the inspection door 2 is provided with a control panel 5. The control panel 5 is electrically connected to the power distribution device 12 and the air exchange pump 17 respectively through conductive lines.

[0051] In specific applications of this invention, the power distribution device 12 and the air exchange pump 17 used in this device are both mature existing technologies, and the working principles of the power distribution device 12 and the air exchange pump 17 are well known to those skilled in the art, so they will not be described in detail here.
