[0002] In a high-load operation state, internal components of a distribution box are prone to generate a large amount of heat due to current passing, and poor heat dissipation will lead to overheating of equipment, performance degradation and even safety accidents.

[0004] According to the above-mentioned patent, the patent realizes directional cooling of the local overheating area, but when the air flow is guided between the multiple heat dissipation areas, the linkage control of the revolution and rotation of the blades is relatively complex, which may cause response delay or uncoordinated action, and affects the heat dissipation efficiency. In addition, when the blades rotate around the shaft to adjust the swing angle, the wind direction control may not be accurate enough due to structural limitations or air flow disturbance, and it is difficult to achieve the optimal local cooling effect.

DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application is described in further detail below in combination with the drawings and specific embodiments.

[0033] Referring to Figures 1-6 and Figure 10 shown, a comprehensive distribution box with a self-rotating airflow guiding and radiating device includes a box body 1, the box body 1 is provided with radiating fans 2 at the top and the bottom, the box body 1 has air outlets 11 at the side edges, the box body 1 is provided with variable air duct structures 3 at the upper half and the lower half of the inner side, the box body 1 is provided with frame bodies 4 for mounting each variable air duct structure 3, the variable air duct structure 3 has flow guide plates 31 distributed at equal intervals along the width direction of the box body 1, flow guide air ducts 311 are formed between every two adjacent flow guide plates 31, each flow guide plate 31 can rotate along the width direction of the box body 1 on the frame body 4, the frame body 4 is provided with a rotating adjusting assembly 5 for driving all the flow guide plates 31 to rotate synchronously and in the same direction, the frame body 4 is provided with temperature sensors 41 at equal intervals along the width direction of the box body 1 below the variable air duct structure 3, when the temperature sensor 41 of a certain area in the box body 1 detects that the area is overheated, the flow guide air duct 311 is in a directional guiding state of deflection towards the overheated area under the rotation of the flow guide plate 31, so that the radiating airflow is concentrated and guided to the overheated area.

[0034] Under normal circumstances, the radiating fans 2 radiate the inside of the box body 1. When the temperature sensor 41 of a certain area in the distribution box detects that the temperature of the area exceeds a preset threshold value, the variable air duct structure 3 is immediately started. The variable air duct structures 3 inside the upper half and the lower half of the box body 1 start to work synchronously.

[0035] In the initial state, the flow guide plates 31 are at the default angle, and at this time the air flow flows along the conventional path and circulates uniformly in the entire box 1 to maintain the stability of the overall temperature. However, when the temperature sensor 41 in a certain area detects local overheating, the control system calculates the optimal rotation angle of the flow guide plates 31 according to the data returned by the temperature sensor 41, so as to guide more cooling air flow to the overheated area.

[0036] Subsequently, the rotation adjustment assembly 5 is started, and all the flow guide plates 31 are rotated at the set angle, so that all the flow guide air ducts 311 are deflected towards the overheated area, so that the cooling air flow from the top or bottom cooling fan 2 is no longer uniformly distributed, but is concentrated to the key position that needs to be cooled. That is, if overheating occurs on the left or right side of the box 1, the angle of the flow guide plates 31 above and below the area will be adjusted to make the air flow converge to the area, enhancing the cooling effect of the area.

[0037] In addition, since the box 1 is provided with cooling fans 2 on the top and the bottom, an upward and downward convection air circulation is formed, and the box 1 is provided with air outlets 11 on the sides, further enhancing the efficiency of air flow. Through the forced ventilation effect of the fan, external cold air is sucked into the box 1, guided to the high-temperature area after passing through the flow guide air duct 311, and then discharged through the air outlet 11 after absorbing heat, thereby realizing efficient local cooling.

[0038] With the deflection of the flow guide plates 31, the originally uniformly distributed air flow is reorganized to form a locally enhanced cooling air flow channel. Not only the cooling efficiency is improved, but also the problem of local overheating caused by uneven air distribution in traditional distribution boxes is avoided. In actual operation, the temperature data fed back by each temperature sensor 41 is continuously monitored, and the angle of the flow guide plates 31 is dynamically adjusted according to the real-time temperature change, so as to realize intelligent and adaptive cooling management. It ensures that the inside of the distribution box is always in a suitable working temperature range, prolongs the service life of the electrical components, and improves the stability and safety of the operation of the distribution box.

[0039] Referring to Figures 3-10 As shown in the figure, a plate body 32 is arranged on the frame 4 between the variable air duct structure 3 and the cooling fan 2, a sealing member 321 is arranged between the plate body 32 and the frame 4, an air outlet 322 is arranged on the plate body 32 corresponding to the position of each flow guide air duct 311, and a flexible sleeve 323 is arranged between the plate body 32 and the adjacent flow guide plate 31, which communicates the corresponding air outlet 322 and the flow guide air duct 311. The air outlet 322 and the flow guide air duct 311 together form an air flow guide path.

[0040] When the heat dissipation fan 2 starts and begins to transport cooling airflow into the cabinet 1, the external cold air first enters through the top or bottom of the cabinet 1 and is guided to the upstream area of the variable air duct structure 3. In the normal running state, the cooling airflow passes through the air port 322, the flexible sleeve 323 in turn, and finally enters the guide air duct 311 formed by the adjacent guide plate 31.

[0041] The flexible sleeve 323 serves as a transition component between the air port 322 and the guide air duct 311, and its interior is a hollow structure that can adapt to the angle change caused by the rotation of the guide plate 31 while maintaining the continuity and sealing of the airflow path. Due to the certain stretchability and deformation ability of the flexible sleeve 323, even when the guide plate 31 is deflected, it can ensure that there is no air leakage or airflow short circuit between the air port 322 and the guide air duct 311, thereby maintaining the stability of the entire guide process.

[0042] When the control system adjusts the angle of the guide plate 31 according to the information fed back by the temperature sensor 41, the rotation adjustment assembly 5 drives all guide plates 31 to rotate synchronously, causing the direction of the guide air duct 311 to change. At the same time, the flexible sleeve 323 will deform accordingly with the rotation of the guide plate 31, continuously and stably transporting the cooling airflow from the air port 322 to the deflected guide air duct 311 under the premise of ensuring the continuity of the airflow guide path. This allows the cooling airflow to always flow along the set guide path and be accurately delivered to the area that needs to be cooled according to the actual heat source distribution.

[0043] In addition, in order to prevent air leakage between the plate body 32 and the frame 4, the sealing member 321 provided therebetween ensures that only the airflow passing through the air port 322 can enter the flexible sleeve 323 and the guide air duct 311, avoiding the disordered diffusion of airflow and energy loss. Therefore, when the guide plate 31 is in the directional guide state, the cooling airflow flows efficiently according to the preset path, thereby improving the local heat dissipation effect.

[0044] Referring to Figures 3-8 and Figure 10 , the frame 4 is provided with a block 3221 corresponding to each air port 322, and the plate body 32 can rotate on the frame 4 in the width direction of the cabinet 1. When the plate body 32 rotates towards the direction of the guide air duct 311, the air ports 322 away from the overheated area gradually approach the corresponding block 3221, while the air ports 322 close to the overheated area gradually move away from the corresponding block 3221, so that the cooling airflow is concentrated and guided to the overheated area.

[0045] The block 3221 functions to cooperate with the air port 322 to reduce the airflow output of the non-overheated area and increase the airflow supply to the overheated area.

[0046] When the overheat phenomenon occurs in a certain area of the box 1, and the air flow guiding path begins to be adjusted to achieve directional heat dissipation, the plate body 32 rotates along the width direction of the box 1. At this time, each air port 322 on the plate body 32 changes its position relative to the corresponding block body 3221 on the frame body 4. During the rotation process, the air ports 322 located on the side away from the overheat area gradually approach the corresponding block bodies 3221, while the air ports 322 located on the side close to the overheat area gradually move away from the corresponding block bodies 3221.

[0047] With the change of the distance between the air ports 322 and the block bodies 3221, the output path of the cooling air flow also changes accordingly. For the air ports 322 gradually approaching the block bodies 3221, the air flow is restricted when passing through the air ports 322 due to the blocking effect of the block bodies 3221, thus effectively reducing the air flow to the non-overheat area. For the air ports 322 gradually moving away from the block bodies 3221, more cooling air flow can smoothly pass through and be concentratedly delivered to the overheat area due to the reduced blocking effect of the block bodies 3221. Not only the precise control of air flow distribution is achieved, but also the cooling capacity of the overheat area is further enhanced.

[0048] Referring to Figures 3-8 and Figure 10 , the block body 3221 is made of rubber material. When the plate body 32 contacts and presses the block body 3221, the block body 3221 is in a deformed state of self-adaptively embedding into the air port 322, so that part of the air ports 322 in the non-overheat area are blocked.

[0049] When the plate body 32 rotates along the width direction of the box 1 on the frame body 4 and gradually approaches the block body 3221, part of the air ports 322 corresponding to the non-overheat area begin to contact the rubber material block body 3221. As the plate body 32 continues to rotate and apply pressure, the block body 3221 elastically deforms at the contact site and self-adaptively embeds into the air port 322, filling part of the flow-through area of the air port 322. The effective flow-through area of the air port 322 is gradually reduced, and even partially blocked when the pressure is sufficient, thereby significantly limiting the cooling air flow to the non-overheat area.

[0050] At the same time, due to the good flexibility and resilience of the rubber material, when the plate body 32 rotates and resets, the block body 3221 can quickly restore its original shape and release the air port 322, ensuring normal air circulation.

[0051] During the whole process, the self-adaptive deformation of the block body 3221 not only achieves dynamic control of the opening and closing degree of the air port 322, but also improves the accuracy of air flow distribution, so that the cooling resources are more concentratedly delivered to the area that really needs cooling, further improving the heat dissipation effect.

[0052] Referring to Figures 3-8 and Figure 10As shown, the frame body 4 is provided with a ventilation grille 42 for fixing all the blocks 3221, and the ventilation grille 42 is arranged opposite to the heat dissipation fan 2.

[0053] When the heat dissipation fan 2 starts and transports the cooling airflow into the box body 1, the airflow first enters the upstream area of the variable air duct structure 3 through the ventilation grille 42 on the frame body 4. As the cooling airflow passes through the ventilation grille 42, its flow path is reasonably distributed to each air port 322, and then enters the guide air duct 311 through the flexible sleeve 323, and finally realizes directional flow guiding according to the angle adjustment of the guide plate 31.

[0054] The ventilation grille 42 not only plays a role in supporting and positioning the blocks 3221, but also has a preliminary flow regulating effect on the airflow, reducing turbulence and airflow turbulence, thereby improving the efficiency and stability of overall heat dissipation. During the entire adjustment process, the ventilation grille 42 always keeps the airflow unobstructed, and cooperates with the action of the blocks 3221 and the plate body 32 to realize precise control of the cooling airflow.

[0055] Referring to Figures 3-8 and Figure 10 As shown, the frame body 4 is provided with a central rotating shaft 43 for shaft connection of the middle part of the plate body 32. When the plate body 32 rotates around the axis of the central rotating shaft 43, one end close to the overheating area is in a downward swing state, and the other end away from the overheating area is in an upward swing state, so that each air port 322 has a gradually increasing air supply trend from the direction away from the overheating area to the direction close to the overheating area.

[0056] When the plate body 32 rotates around the axis of the central rotating shaft 43, the whole plate body 32 changes in an inclined posture, one end close to the overheating area swings downward, and the other end away from the overheating area swings upward, so that each air port 322 on the plate body 32 presents a gradually increasing air supply angle change along the width direction of the box body 1.

[0057] With the rotation of the plate body 32, the air ports 322 away from the overheating area gradually rise and approach the blocks 3221, and the airflow output is limited, while the air ports 322 close to the overheating area gradually lower and move away from the blocks 3221, the flow area increases, and the cooling airflow can be output more smoothly.

[0058] Referring to Figures 3-8 and Figure 10 As shown, the sealing member 321 is made of a flexible material that can adaptively deform according to the rotating action of the plate body 32.

[0059] When the plate body 32 rotates around the central rotating shaft 43 for adjustment, the contact surface between the plate body 32 and the frame body 4 deforms accordingly. Since the sealing member 321 is made of a flexible material, it can adaptively adjust in real time according to the change of the rotation angle of the plate body 32.

[0060] The plate body 32 is always kept in close contact during deflection. The gap change caused by the movement of the plate body 32 is effectively compensated, preventing cooling air from leaking from unintended gaps, and ensuring that the air flow enters the air inlet 322 and the flow guide duct 311 according to the set path.

[0061] Referring to Figure 2 and Figure 9 , the frame body 4 is provided with an adjustment shaft 44 for the shaft connection of each flow guide plate 31, and the rotation adjustment assembly 5 includes a first gear 51 and a first rack 52. Each adjustment shaft 44 is provided with a first gear 51, and all first gears 51 are meshed with the first rack 52, which can move on the frame body 4 along the width direction of the box body 1.

[0062] When it is necessary to adjust the angle of the flow guide plate 31 to realize air flow guiding control, the first rack 52 is translated on the frame body 4 along the width direction of the box body 1. With the movement of the first rack 52, all first gears 51 rotate synchronously, and the corresponding adjustment shaft 44 is rotated.

[0063] So that each flow guide plate 31 will have an angle deflection around its adjustment shaft 44, and the rotation direction and angle of all flow guide plates 31 remain consistent, ensuring the synchronous adjustment of each flow guide duct 311 in the entire variable air duct structure 3, so that the air flow is concentrated and guided to the overheated area according to the temperature distribution in the box body 1, completing the efficient and directional heat dissipation process.

[0064] Referring to Figure 2 and Figure 9 , the frame body 4 is provided with a synchronous adjustment assembly 6 for driving the plate body 32 to rotate following the action of the flow guide plate 31.

[0065] When the flow guide plate 31 is angularly deflected under the action of the rotation adjustment assembly 5, the synchronous adjustment assembly 6 responds immediately and drives the plate body 32 to act synchronously. In this process, the plate body 32 rotates around the central shaft 43, and the relative position between the air inlet 322 and the block body 3221 changes, so that the air inlets 322 away from the overheated area are gradually blocked, and the air inlets 322 close to the overheated area are further opened, thereby realizing the directional enhancement of the cooling air flow output.

[0066] This synchronous process ensures that the air flow guiding of the flow guide duct 311 and the layout of the air inlet 322 of the plate body 32 always match, maintains efficient and stable air flow organization, improves local heat dissipation capacity, and realizes accurate response and regulation of the heat field distribution in the box body 1.

[0067] Referring to Figure 2 and Figure 9As shown, the synchronous adjustment assembly 6 comprises a second gear 61 arranged on the central rotating shaft 43 and a second rack 62 engaged with the second gear 61, the second rack 62 is movable along the width direction of the box body 1 on the frame body 4, and the synchronous adjustment assembly 6 further comprises a linear driver for driving the synchronous movement of the first rack 52 and the second rack 62.

[0068] The linear driver is not shown in the figure.

[0069] When it is necessary to adjust the angle of the flow guide plate 31 and synchronously drive the rotation of the plate body 32, the linear driver is started to drive the synchronous movement of the first rack 52 and the second rack 62 along the width direction of the box body 1. The movement of the first rack 52 drives the rotation of all the first gears 51 engaged with the first rack 52, thereby driving the synchronous deflection of each flow guide plate 31 around the adjusting rotating shaft 44, realizing the directional control of the airflow direction.

[0070] At the same time, the movement of the second rack 62 also drives the rotation of the second gear 61 engaged with the second rack 62, thereby driving the rotation of the plate body 32 around the central rotating shaft 43, so that the angle adjustment of the flow guide plate 31 is kept synchronous with the rotation action of the plate body 32, ensuring that the relative position change between the air outlet 322 and the block body 3221 is consistent with the airflow guiding direction of the flow guide air duct 311, further improving the concentration of the cooling airflow and the heat dissipation efficiency, and realizing the precise cooling of the overheated area.

[0071] The present application realizes the precise guidance and local reinforced heat dissipation of the cooling airflow through the synchronous adjustment of the angle of the flow guide plate 31 in the variable air duct structure 3, combined with the dynamic cooperation between the plate body 32 and the block body 3221. When the temperature sensor 41 detects the overheated area, the rotary adjustment assembly 5 drives the deflection of all the flow guide plates 31, so that the cooling airflow is concentrated and delivered to the overheated area.

[0072] At the same time, the plate body 32 rotates around the central rotating shaft 43, the air outlet 322 swings with it and has a relative displacement with the block body 3221 made of rubber material, the air outlets 322 far away from the overheated area are gradually blocked, and the air outlets 322 close to the area increase the flow area, forming a gradually enhanced air supply trend from far to near. The heat dissipation efficiency and airflow distribution accuracy are improved, effectively preventing heat accumulation, and ensuring that the inside of the distribution box is always in a balanced and safe thermal environment.

1. A comprehensive power distribution box with a self-rotating airflow guiding heat dissipation device, comprising a box body, wherein cooling fans are provided at the top and bottom of the box body, and air outlets are provided on the sides of the box body; characterized in that, The upper and lower halves of the inner side of the enclosure are equipped with variable air duct structures. The enclosure has a frame for mounting each variable air duct structure. Each variable air duct structure has several air guide plates evenly spaced along the width of the enclosure, forming an air duct between every two adjacent air guide plates. Each air guide plate can rotate on the frame along the width of the enclosure. The frame is equipped with a rotation adjustment component to drive all air guide plates to rotate synchronously and in the same direction. Several temperature sensors are evenly spaced along the width of the enclosure and located on the frame below the variable air duct structures. When a temperature sensor in a certain area of ​​the enclosure detects overheating, the air ducts, under the rotation of the air guide plates, are in a directional flow state deflected towards the overheated area, concentrating the cooling airflow to the overheated area. A plate is located on the frame between the variable air duct structures and the cooling fan. A sealing element is provided between the plates, and an air vent is provided at the position of each air duct on the plate. A flexible sleeve connecting the corresponding air vent and the air duct is provided between the plate and the adjacent air duct. The air vent and the air duct together form an airflow guiding path. A central rotating shaft is provided on the frame for the middle part of the plate to be axially connected. When the plate rotates around the axis of the central rotating shaft, the end closer to the overheated area is in a downward swing state, and the end farther away from the overheated area is in an upward swing state, so that each air vent forms a progressively stronger air supply trend from the direction away from the overheated area to the direction closer to the overheated area. An adjusting rotating shaft is provided on the frame for each air duct to be axially connected. The rotating adjusting component includes a first gear and a first rack. Each adjusting rotating shaft is provided with a first gear. All first gears mesh with the first rack. The first rack can move along the width direction of the box on the frame.

2. A comprehensive power distribution box with a self-rotating airflow guiding heat dissipation device according to claim 1, characterized in that, Each air vent on the frame has a block at its corresponding position. The block can rotate along the width of the box on the frame. When the block rotates toward the direction of the air duct, the air vents away from the overheated area gradually approach the corresponding block, while the air vents close to the overheated area gradually move away from the corresponding block, so that the cooling airflow is concentrated and directed toward the overheated area.

3. A comprehensive power distribution box with a self-rotating airflow guiding heat dissipation device according to claim 2, characterized in that, The block is made of rubber. When the plate contacts and squeezes the block, the block is in a self-adaptive deformation state that embeds into the air vent, thus blocking some of the air vents in the non-overheated area.

4. A comprehensive power distribution box with a self-rotating airflow guiding heat dissipation device according to claim 3, characterized in that, The frame is equipped with ventilation grilles for fixing all the blocks, and the ventilation grilles are positioned directly opposite the cooling fan.

5. A comprehensive power distribution box with a self-rotating airflow guiding heat dissipation device according to claim 1, characterized in that, The seal is made of a flexible material that can adapt to the rotation of the plate.

6. A comprehensive power distribution box with a self-rotating airflow guiding heat dissipation device according to claim 1, characterized in that, The frame is equipped with a synchronous adjustment component to drive the plate to rotate in accordance with the movement of the diversion plate.

7. A comprehensive power distribution box with a self-rotating airflow guiding heat dissipation device according to claim 6, characterized in that, The synchronization adjustment assembly includes a second gear mounted on a central rotating shaft and a second rack meshing with it. The second rack is capable of moving along the width of the housing on the frame. The synchronization adjustment assembly also includes a linear driver for driving the first rack and the second rack to move synchronously.
