Description

Technical Field

[0001] This application relates to the field of distribution box technology, and more specifically, to an outdoor integrated distribution box with enhanced heat dissipation. Background Technology

[0002] In outdoor power systems, integrated distribution boxes are key equipment for power distribution. Their stable operation is crucial to ensuring the reliability of the entire power supply. However, the outdoor environment is complex. In high-temperature environments, the electronic components inside the distribution box will generate a lot of heat. Overheating of electronic components will degrade their performance, shorten their lifespan, or even cause failures, thus affecting the reliability of the power supply. At the same time, dust and other pollutants in the outdoor environment can enter the distribution box with the airflow, damaging the electronic components.

[0003] In traditional outdoor integrated distribution boxes, fans are usually fixed in place, which keeps the airflow direction constant. However, in actual operation, when the air outlet of the distribution box faces the direction of the natural wind, the airflow driven by the fan is reversed, which hinders the effective airflow and causes the fan's heat dissipation effect to decrease significantly. At the same time, dust in existing distribution boxes is easy to adhere to the surface of electronic components, which prevents the heat of electronic components from being dissipated effectively.

[0004] Therefore, there is an urgent need for an outdoor integrated power distribution box that can adapt to different wind directions. Summary of the Invention

[0018] This application provides an outdoor integrated power distribution box with enhanced heat dissipation that can adapt to different wind directions, achieving efficient heat dissipation. During operation, the electronic components inside the distribution box generate a large amount of heat. Simultaneously, a wind vane mounted on the rotating cover rotates according to the direction of the outdoor natural wind, causing the rotating cover to rotate as well. This ensures the air intake side of the rotating cover faces the wind direction, allowing natural wind to smoothly enter the rotating cover and carry away the heat from the heat dissipation fins. Furthermore, the natural wind impacts the fan blades, causing them to rotate around their axis. The power generated by the fan blades is transmitted to the distribution box, increasing the airflow speed inside and rapidly cooling the heat, creating good air circulation and achieving efficient heat dissipation. At the same time, by placing the heat dissipation fins on the top of the distribution box, the traditional airflow path for heat dissipation is changed, reducing the disadvantages of traditional side-mounted cooling fans that allow dust to enter. This reduces damage to the electronic components inside the box from external dust, rain, and other factors, improving the overall protective effect of the distribution box.

[0041] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0042] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0043] The following reference Figures 1 to 14 This application describes an outdoor integrated power distribution box with enhanced heat dissipation provided according to some embodiments.

[0044] like Figure 1 , Figure 2As shown, the outdoor integrated power distribution box with enhanced heat dissipation provided according to some embodiments of this application includes a power distribution box body 100, a heat exchange mechanism 200, a cooling mechanism 300, and an air-cooling mechanism 400. The heat exchange mechanism 200 is disposed on the power distribution box body 100 and includes multiple heat dissipation fins 241, all disposed on the top of the power distribution box. The cooling mechanism 300 is disposed on the top of the power distribution box body 100 and includes: a rotating cover 320 rotatably connected to the power distribution box body 100, with the multiple heat dissipation fins 241 housed within the rotating cover 320; a wind vane 350 disposed on the rotating cover 320, capable of adjusting the direction of the rotating cover 320 according to the direction of the incoming wind; and the air-cooling mechanism 400 is disposed on the top of the power distribution box body 100 and extends through the rotating cover 320, including multiple fan blades 410 disposed on the opposite side of the wind vane 350, capable of rotating using natural wind and transmitting power to the power distribution box.

[0045] In this embodiment, the electronic components inside the distribution box generate a large amount of heat during operation. Simultaneously, the wind vane 350, mounted on the rotating cover 320, rotates according to the direction of the outdoor natural wind, thereby causing the rotating cover 320 to rotate as well. This ensures that the air intake side of the rotating cover 320 faces the direction of the wind, allowing natural wind to smoothly enter the rotating cover 320 and carry away the heat from the heat dissipation fins 241. Furthermore, the natural wind impacts the fan blades 410, causing them to rotate around their axis. The power generated by the fan blades 410 is transmitted to the distribution box, increasing the airflow speed inside the box and rapidly cooling the heat. This creates a good air circulation and achieves efficient heat dissipation. At the same time, by placing the heat dissipation fins 241 on the top of the distribution box 100, the traditional airflow path for heat dissipation is changed, reducing the disadvantage of dust entering the box due to the traditional cooling fan being located on the side of the distribution box 100. This reduces damage to the electronic components inside the box from external dust, rain, and other factors, improving the overall protective effect of the distribution box 100.

[0046] In some possible embodiments, such as Figures 1 to 3 As shown, it also includes: a door 110, which is rotatably connected to the distribution box 100; two fixed frames 120, which are symmetrically arranged on the distribution box 100; a heat exchange plate 130, which is arranged on the two fixed frames 120; multiple mounting strips 140, which are arranged on the heat exchange plate 130 and are used to install electronic components; and a support platform 150, which is arranged on the top of the distribution box 100 and has a circular sliding groove on the top.

[0047] In this embodiment, multiple mounting strips 140 facilitate the installation of electronic components; the door 110 effectively prevents external dust, rain, debris, etc. from entering the distribution box, protecting the internal electronic components and wiring; two fixed frames 120 provide stable support for the heat exchange plate 130; the heat exchange plate 130 has good thermal conductivity and can quickly absorb and conduct the heat generated by the electronic components.

[0048] In some possible embodiments, such as Figures 4 to 7 As shown, the heat exchange mechanism 200 also includes: a water tank 210, located on the side of the heat exchange plate 130 away from the mounting strip 140; multiple heat-absorbing fins 220, respectively disposed on the water tank 210; a riser pipe 230, one end of which is connected to the water tank 210; a heat dissipation plate 240, located on the top of the support platform 150 and connected to the other end of the riser pipe 230, with multiple heat dissipation fins 241 respectively disposed on the heat dissipation plate 240; a return pipe 250, one end of which is connected to the heat dissipation plate 240 and is symmetrically arranged with the riser pipe 230, with the other end of the return pipe 250 connected to the water tank 210; and a flow guide hood 260, located on the power distribution box 100.

[0049] In this embodiment, the electronic components inside the distribution box generate a large amount of heat during operation. This heat is conducted to the heat exchange plate 130 through the mounting strip 140. The heat exchange plate 130 is connected to the water tank 210, and multiple heat-absorbing fins 220 are provided on the other side of the water tank 210. These heat-absorbing fins 220 can absorb the heat in the distribution box environment and transfer the heat to the water tank 210. After absorbing heat, the coolant in the water tank 210 increases in temperature and decreases in density. According to the principle of thermal expansion and contraction, the density of the hot coolant is less than that of the cold coolant. Under the action of gravity difference and thermal convection, the hot coolant flows upward through the riser pipe 230 and is transported from the water tank 210 to the heat dissipation plate located on the top of the support platform 150. 240. The heat in the coolant is dissipated through multiple heat dissipation fins 241 on the heat sink 240. The large surface area of ​​the heat dissipation fins 241 increases the contact area with the air. At the same time, the air shroud 260 guides the surrounding air to flow more effectively through the heat dissipation fins 241, accelerating the heat dissipation process. As the heat is dissipated, the temperature of the coolant gradually decreases. After the temperature decreases, the density of the coolant increases. Under the action of gravity, it flows back to the water tank 210 through the return pipe 250. Then, through the circulation of the coolant, the heat is dissipated into the air by the heat sink 240, thereby achieving continuous heat dissipation for the electronic components in the distribution box, greatly improving the heat dissipation efficiency, better adapting to the high temperature outdoor environment, and ensuring the operation of the electronic components.

[0050] In some possible embodiments, such as Figures 7 to 9As shown, the cooling mechanism 300 also includes: a rotary track 310, which is set on a circular slide rail of the support platform 150, and the rotating cover 320 is fixedly connected to the rotary track 310; two fans 330, which are symmetrically arranged on both sides of the rotating cover 320; and a riser 340, which is set on the top of the rotating cover 320, with the wind vane 350 and the fan blades 410 symmetrically arranged on the riser 340.

[0051] In this embodiment, the outdoor natural wind is constantly changing direction. The wind vane 350, through its special streamlined structure, can sense the direction of the incoming wind in real time. When the wind direction changes, the wind vane 350 will adjust its own direction and transmit power to the rotating cover 320. The rotating cover 320 rotates on the rotary track 310 of the support platform 150, so that the opening of the rotating cover 320 corresponds to the direction of the incoming wind. At the same time, the two fans 330 set on both sides of the rotating cover 320 rotate. The high-speed rotation of the fan blades generates a strong suction and exhaust capacity, drawing the natural wind into the rotating cover 320 and exhausting it through the other fan 330, forming an orderly airflow. The airflow comes into contact with the heat dissipation fins 241 on the heat dissipation plate 240, carrying away the heat on the heat dissipation fins 241, forming an air circulation, effectively reducing the temperature inside the distribution box.

[0052] In this design, the wind vane 350 enables the rotating cover 320 to automatically adjust according to the direction of the natural wind, ensuring that the natural wind can enter the rotating cover 320 to the maximum extent and be accelerated and utilized by the fan 330, making full use of outdoor natural wind energy and avoiding the situation of natural wind blowing against each other. At the same time, the heat exchange process is set at the top of the distribution box, reducing the amount of dust and other impurities brought in by the air directly entering the distribution box and adhering to the electronic components. This changes the traditional heat exchange path, reduces the chance of dust coming into contact with electronic components, and reduces the risk of dust adhesion.

[0053] In some possible embodiments, such as Figures 9 to 13As shown, the air-cooling mechanism 400 further includes: a long shaft 420, passing through the riser 340; a bevel gear set 430, disposed on the long shaft 420; a connector 421, disposed at the end of the long shaft 420; a short shaft 460, disposed at the end of the long shaft 420 away from the bevel gear set 430; a mounting box 440, disposed on the distribution box 100; a fan cover 450, disposed on the mounting box 440; a fan blade 470, disposed at the end of the short shaft 460 away from the long shaft 420; a connecting plate 480, connected to the connector 421, the connecting plate 480 having an oblique guide groove and a protrusion; the bevel gear set 430 includes: a driving bevel gear 431, disposed on the output shaft of the fan blade 410; a driven bevel gear 431; and a driven bevel gear 430. A bevel gear 432 is mounted on the long shaft 420 and meshes with the driving bevel gear 431. The connecting member 421 includes: a first connecting member, mounted on the end of the long shaft 420 near the short shaft 460, with a protrusion on the outer side of the first connecting member; a second connecting member, mounted on the end of the short shaft 460 near the long shaft 420, with the first connecting member in contact with the second connecting member, and a limiting groove inside the second connecting member; the protrusion of the connecting plate 480 can slide within the limiting groove of the second connecting member and can cooperate with the protrusion of the first connecting member; the heat exchange plate 130 has a vent inside, and a flow guide 260 is mounted at the vent, extending outward to the heat absorption fins 220.

[0054] In this embodiment, when there is a natural wind in the outdoor environment, the fan blade 410 begins to rotate under the action of the wind. The output shaft of the fan blade 410 transmits the rotational power to the driving bevel gear 431. The driving bevel gear 431 drives the driven bevel gear 432, which meshes with it, to rotate. The driven bevel gear 432 is fixed on the long shaft 420, thereby transmitting power to the long shaft 420, causing the long shaft 420 to start rotating. Through the cooperation of the first connecting member, the second connecting member, and the connecting plate 480, the power is transmitted to the short shaft 460. The short shaft 460 drives the fan blade 470 to rotate, producing... The suction force draws air from the front-end electronic component mounting area inside the distribution box 100 into the mounting box 440. The hot air is guided by the fan shroud 450, passes through the ventilation opening of the heat exchange plate 130, and is delivered to the rear-end heat exchange area inside the distribution box 100. It is then transferred by the air guide shroud 260 to the heat-absorbing fins 220. The heat-absorbing fins 220 can transfer heat to the coolant in the water tank 210. After heat exchange by the heat-absorbing fins 220, the air inside the distribution box 100 returns to the electronic component mounting area after ventilation at the bottom of the heat exchange plate 130, thus achieving efficient heat dissipation of the distribution box 100.

[0055] In some possible embodiments, such as Figures 11 to 14As shown, it also includes a switching mechanism 500, which is disposed within the mounting box 440. The switching mechanism 500 includes: a motor 510, disposed on the mounting box 440; a fixed bevel gear 520, disposed on the output shaft of the motor 510; a lifting bevel gear 521, disposed on the short shaft 460 and meshing with the fixed bevel gear 520; a liquid storage tube 530, disposed on the side of the mounting box 440 away from the motor 510, the liquid storage tube 530 including a horizontal tube and a vertical tube; a piston 540, disposed inside the horizontal tube of the liquid storage tube 530; a heat absorption rod 550, disposed inside the vertical tube of the liquid storage tube 530; a moving column 560, disposed at the output end of the piston 540; a roller 570, disposed at one end of the moving column 560, and the mounting box 440 has a moving groove for supplying movement of the roller 570; and a ball bearing 580, disposed on the side of the moving column 560 away from the roller 570, and the ball bearing 580 contacts the inclined guide groove of the connecting plate 480.

[0056] In this embodiment, when there is no natural wind or the natural wind is weak and cannot meet the effective heat dissipation requirements of the distribution box 100, the heat in the distribution box continuously increases. The heat-absorbing rod 550 senses the heat inside the box and its temperature rises, causing the liquid in the liquid storage pipe 530 to expand due to the increased temperature. This causes a change in the liquid pressure inside the liquid storage pipe 530, which in turn pushes the piston 540 in the horizontal pipe to move. The movement of the piston 540 drives the moving column 560 and the roller 570 to move. At the same time, the ball bearing 580 rolls in the inclined guide groove of the connecting plate 480. As the ball bearing 580 moves in the inclined guide groove... When the device moves to a flat area, the connecting plate 480 moves down, causing the lifting bevel gear 521 to move down and mesh with the fixed bevel gear 520. At this time, the motor 510 is started, causing the fixed bevel gear 520 to rotate. The fixed bevel gear 520 drives the lifting bevel gear 521 to rotate through meshing transmission, which in turn drives the short shaft 460 to rotate. The short shaft 460 drives the fan blade 470 to rotate, generating a strong suction force, which draws the heat from the distribution box 100 into the mounting box 440 and conducts it. At this time, because the connecting plate 480 moves down, it will not drive the first connecting piece and the long shaft 420 to rotate.

[0057] In this design, the switching mechanism 500 provides dual heat dissipation protection for the distribution box 100. When there is natural wind, it prioritizes the use of natural wind energy for heat dissipation, which is energy-saving and environmentally friendly. When there is no natural wind or the natural wind is insufficient to meet the heat dissipation requirements, it can immediately switch to the heat dissipation mode driven by the motor 510, ensuring that the distribution box 100 is always within a suitable operating temperature range, thereby improving the reliability and stability of the equipment.

[0058] When the outdoor integrated power distribution box with enhanced heat dissipation is in operation, the electronic components inside the distribution box generate heat. This heat is conducted to the heat exchange plate 130 through the mounting strip 140, while the heat absorption fins 220 absorb the heat inside the distribution box 100. Both the heat exchange plate 130 and the heat dissipation fins 241 transfer heat to the water tank 210. At this time, if there is natural wind in the outdoor environment, the wind vane 350, with its streamlined structure, senses the direction of the wind in real time and transmits power to the rotating cover 320. The rotating cover 320 rotates on the rotary track 310 of the support platform 150, aligning the position of its suction fan 330 with the direction of the wind. The natural wind impacts the fan blades 410, causing them to rotate. The output shaft transmits power to the driving bevel gear 431, which in turn drives the driven bevel gear 420. The long shaft 420 rotates, and through the cooperation of the first connector, the second connector, and the connecting plate 480, the long shaft 420 transmits power to the short shaft 460. The short shaft 460 drives the fan blades 470 to rotate, generating suction to draw air from the front electronic component mounting area inside the distribution box 100 into the mounting box 440. The hot air is guided by the fan shroud 450 and transported through the ventilation opening of the heat exchange plate 130 to the rear heat exchange area inside the distribution box 100. The air is then transferred by the guide shroud 260 to the heat-absorbing fins 220, which transfer heat to the coolant in the water tank 210. After heat exchange by the heat-absorbing fins 220, the air inside the distribution box 100 returns to the electronic component mounting area through the bottom ventilation of the heat exchange plate 130, achieving initial heat dissipation. The coolant in the water tank 210... After absorbing heat, the coolant's temperature rises and its density decreases. Under the influence of gravity and thermal convection, the hot coolant rises through the riser pipe 230 to the heat sink 240. The cooling fins 241 on the heat sink 240 increase the contact area with the air. The high-speed rotation of the fan blades 330 generates strong suction and exhaust capabilities, drawing natural air into the rotating shroud 320 and exhausting it through another fan 330, forming an orderly airflow. The airflow contacts the cooling fins 241 on the heat sink 241, carrying away the heat from the fins. As a result, the coolant temperature in the heat sink 240 decreases and its density increases. Under the influence of gravity, it flows back to the water tank 210 through the return pipe 250, forming a circulating cooling system. When there is no natural wind or the natural wind is too weak to meet the cooling needs of the distribution box... When demand causes the heat inside the chamber to rise continuously, the heat-absorbing rod 550 senses the heat and its temperature rises, causing the liquid in the storage tube 530 to expand. This changes the liquid pressure inside the storage tube 530, pushing the piston 540 in the horizontal tube to move. The piston 540 drives the moving column 560 and roller 570 to move, and the ball bearing 580 rolls in the inclined guide groove of the connecting plate 480. When the ball bearing 580 moves to the planar area, the connecting plate 480 moves down, causing the lifting bevel gear 521 to move down and mesh with the fixed bevel gear 520. At this time, the motor 510 starts, driving the fixed bevel gear 520 to rotate. The fixed bevel gear 520 drives the lifting bevel gear 521 to rotate, which in turn drives the short shaft 460 to rotate. The short shaft 460 drives the fan blade 470 to rotate, generating a strong suction force.The heat from the distribution box is drawn into the mounting box 440 and conducted to the heat-absorbing fins 220, achieving efficient heat dissipation.
