DETAILED DESCRIPTION

[0019] In order to enable a more complete understanding of the above-mentioned objects, features and advantages of the present application, the present application will be described in further detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in other ways different from those described herein, and the scope of the present application is not limited to the specific embodiments disclosed below.

[0021] The following description refers to the accompanying drawings that show embodiments of the present application. Figures 1 to 14 The outdoor integrated distribution box with enhanced heat dissipation is provided according to some embodiments of the present application.

[0022] As shown in Figure 1 , Figure 2 The outdoor integrated distribution box with enhanced heat dissipation provided according to some embodiments of the present application includes a 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 arranged on the distribution box body 100 and includes a plurality of heat dissipation fins 241, which are arranged on the top of the distribution box. The cooling mechanism 300 is arranged on the top of the distribution box body 100. The cooling mechanism 300 includes a rotating cover 320, which is rotatably connected to the distribution box body 100, and the plurality of heat dissipation fins 241 are accommodated in the rotating cover 320. A wind vane 350 is arranged on the rotating cover 320. The wind vane 350 can adjust the direction of the rotating cover 320 according to the direction of the wind. The air cooling mechanism 400 is arranged on the top of the distribution box body 100 and penetrates the rotating cover 320. The air cooling mechanism 400 includes a plurality of fan blades 410, which are arranged on the side opposite to the wind vane 350. The plurality of fan blades 410 can be rotated by natural wind and transmit power to the distribution box.

[0023] In this embodiment, the electronic components in the distribution box generate a large amount of heat during operation, and at the same time, the wind vane 350 arranged on the rotating cover 320 rotates according to the direction of the outdoor natural wind, thereby driving the rotating cover 320 to rotate, so that the air inlet side of the rotating cover 320 faces the direction of the incoming wind. The natural wind smoothly enters the rotating cover 320, carries away the heat of the heat dissipation fins 241, and the natural wind will impact the fan blades 410, causing the fan blades 410 to rotate around the shaft, and the power generated by the fan blades 410 is transmitted to the distribution box, increasing the flow speed of the air in the distribution box, rapidly cooling the heat, forming good air circulation, and achieving efficient heat dissipation. At the same time, by arranging the heat dissipation fins 241 on the top of the distribution box body 100, the traditional air flow path for heat dissipation is changed, the disadvantage of the traditional heat dissipation fan being arranged on the side of the distribution box body 100 and being prone to entering dust is reduced, the damage of external dust, rainwater and other factors to the electronic components in the box is reduced, and the protection effect of the entire distribution box body 100 is improved.

[0024] In some possible embodiments, as shown in Figures 1 to 3 The box door 110 is rotatably connected with the distribution box body 100, the two fixed frames 120 are symmetrically arranged on the distribution box body 100, the heat exchange plate 130 is arranged on the two fixed frames 120, the plurality of mounting strips 140 are arranged on the heat exchange plate 130, and the plurality of mounting strips 140 are used for mounting electronic components. The support table 150 is arranged on the top of the distribution box body 100, and the top of the support table 150 has a circular sliding groove.

[0025] In this embodiment, the plurality of mounting strips 140 provide convenience for the mounting of electronic components; the box door 110 can effectively block dust, rainwater, sundries and the like in the outside from entering the inside of the distribution box, and protect the electronic components and lines inside; the two fixed frames 120 provide stable support for the heat exchange plate 130; and the heat exchange plate 130 has good heat conduction performance and can quickly absorb and conduct the heat generated by the electronic components.

[0026] In some possible embodiments, as shown in Figures 4 to 7 The heat exchange mechanism 200 further includes a water tank 210 arranged on a side of the heat exchange plate 130 away from the mounting strips 140, a plurality of heat absorption fins 220 arranged on the water tank 210, a liquid lifting pipe 230 connected with one end of the water tank 210, a heat dissipation disc 240 arranged on the top of the support table 150 and connected with the other end of the liquid lifting pipe 230, a plurality of heat dissipation fins 241 arranged on the heat dissipation disc 240, a liquid return pipe 250 connected with the heat dissipation disc 240 at one end and arranged in a symmetrical position with the liquid lifting pipe 230, and the other end of the liquid return pipe 250 is connected with the water tank 210. A drainage cover 260 is arranged on the distribution box body 100.

[0027] In this embodiment, the electronic components in the distribution box generate a large amount of heat during operation, which is conducted to the heat exchange plate 130 through the mounting strip 140, the heat exchange plate 130 is connected with the water tank 210, and the other side of the water tank 210 is also provided with a plurality of heat absorbing fins 220, which can absorb heat in the environment of the distribution box and transmit the heat to the water tank 210. After the cooling liquid in the water tank 210 absorbs heat, the temperature rises and the density decreases. According to the principle of thermal expansion and contraction, the density of hot cooling liquid is smaller than that of cold cooling liquid. Under the action of gravity difference and thermal convection, the hot cooling liquid flows upward through the riser pipe 230 from the water tank 210 to the heat dissipation disc 240 located at the top of the support table 150, and the heat in the cooling liquid is dissipated through the plurality of heat dissipation fins 241 on the heat dissipation disc 240. The large surface area of the heat dissipation fins 241 increases the contact area with air, and the flow guide cover 260 guides the surrounding air to flow more effectively through the heat dissipation fins 241, accelerating the heat dissipation process. With the dissipation of heat, the temperature of the cooling liquid gradually decreases, and the density of the cooling liquid increases after the temperature decreases. Under the action of gravity, the cooling liquid flows back to the water tank 210 through the return pipe 250, and the heat is dissipated to the air by the heat dissipation disc 240 through the circulation of the cooling liquid, thereby realizing continuous heat dissipation of the electronic components in the distribution box, greatly improving the heat dissipation efficiency, and better adapting to outdoor high-temperature environment to ensure the operation of the electronic components.

[0028] In some possible embodiments, as shown in Figures 7 to 9 The cooling mechanism 300 further includes: a rotary track 310 arranged on the circular slide rail of the support table 150, and a rotating cover 320 fixedly connected with the rotary track 310; two fans 330 symmetrically arranged on two sides of the rotating cover 320; a vertical pipe 340 arranged on the top of the rotating cover 320, and a wind vane 350 and a fan blade 410 symmetrically arranged on the vertical pipe 340.

[0029] In this embodiment, the outdoor natural wind changes direction constantly, the wind vane 350 can sense the direction of the incoming wind in real time through its special streamline structure, and when the wind direction changes, the wind vane 350 adjusts its own direction and transmits power to the rotating cover 320. The rotating cover 320 rotates on the rotary track 310 of the support table 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 arranged on both sides of the rotating cover 320 rotate, and the high-speed rotation of the fan blade 330 produces strong suction and exhaust capacity, which sucks the natural wind into the rotating cover 320 and discharges it through the other fan 330, forming an orderly air flow. The air flow contacts the heat dissipation fins 241 on the heat dissipation disc 240, carries away the heat on the heat dissipation fins 241, forms air circulation, and effectively reduces the temperature in the distribution box.

[0030] In the design, the wind vane 350 enables the rotating cover 320 to automatically adjust according to the wind direction of the natural wind, ensures that the natural wind can enter the rotating cover 320 to the maximum extent and be accelerated by the fan 330, fully utilizes the natural wind energy outdoors, and avoids the natural wind blowing situation, at the same time, the heat exchange process is arranged at the top of the distribution box, reduces the air directly entering the distribution box to bring impurities such as dust into the electronic components, changes the traditional heat exchange path, reduces the contact opportunity of dust and electronic components, and reduces the risk of dust adhesion.

[0031] In some possible embodiments, as shown in Figures 9 to 13 The air cooling mechanism 400 further includes: a long shaft 420 arranged on the stand pipe 340; a bevel gear set 430 arranged on the long shaft 420; a connecting piece 421 arranged at the end of the long shaft 420; a short shaft 460 arranged at the end of the long shaft 420 away from the bevel gear set 430; a mounting box 440 arranged on the distribution box body 100; a fan cover 450 arranged on the mounting box 440; a fan blade 470 arranged at the end of the short shaft 460 away from the long shaft 420; a connecting disc 480 connected with the connecting piece 421, the connecting disc 480 has an inclined guide groove and a protruding block; the bevel gear set 430 includes: a driving bevel gear 431 arranged on the output shaft of the fan blade 410; a driven bevel gear 432 arranged on the long shaft 420 and meshed with the driving bevel gear 431; the connecting piece 421 includes: a first connecting piece arranged at the end of the long shaft 420 close to the short shaft 460, the first connecting piece has a protruding block outside; a second connecting piece arranged at the end of the short shaft 460 close to the long shaft 420, and the first connecting piece and the second connecting piece are in contact, the second connecting piece has a limiting groove inside; the protruding block of the connecting disc 480 can slide in the limiting groove of the second connecting piece and cooperate with the protruding block of the first connecting piece; the heat exchange plate 130 has a ventilation opening inside, the flow guide cover 260 is arranged at the ventilation opening, and the flow guide cover 260 extends outward to the heat absorption fin 220.

[0032] In this embodiment, when there is natural wind blowing in the outdoor environment, the fan blade 410 starts to rotate under the action of the wind, and the output shaft of the fan blade 410 transmits the rotational power to the active bevel gear 431, and the active bevel gear 431 drives the driven bevel gear 432 meshed with it to rotate, and the driven bevel gear 432 is fixed on the long shaft 420, thereby transmitting the power to the long shaft 420, causing the long shaft 420 to start rotating, and 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, and the short shaft 460 drives the fan blade 470 to rotate, producing Suction is generated to draw air from the front electronic component installation area in the distribution box 100 into the installation box 440. The hot air is guided by the air hood 450 and passes through the ventilation port of the heat exchange plate 130 to the rear heat exchange area in the distribution box 100. That is, it is transferred to the heat-absorbing fins 220 by the drainage hood 260. The heat-absorbing fins 220 can transfer heat to the coolant in the water tank 210. After heat exchange through the heat-absorbing fins 220, the air in the distribution box 100 is ventilated through the bottom of the heat exchange plate 130 and returns to the electronic component installation area, thereby achieving efficient heat dissipation of the distribution box 100.

[0033] In some possible embodiments, such as Figures 11 to 14 As shown, it also includes a switching mechanism 500, which is arranged in the installation box 440, and the switching mechanism 500 includes: a motor 510, which is arranged on the installation box 440; a fixed bevel gear 520, which is arranged on the output shaft of the motor 510; a lifting bevel gear 521, which is arranged on the short shaft 460 and meshes with the fixed bevel gear 520; a liquid storage tube 530, which is arranged on the side of the installation box 440 away from the motor 510, and the liquid storage tube 530 includes a horizontal tube and a vertical tube; a piston 540, which is arranged in the horizontal tube of the liquid storage tube 530; a heat absorbing rod 550, which is arranged in the vertical tube of the liquid storage tube 530; a moving column 560, which is arranged at the output end of the piston 540; a roller 570, which is arranged at one end of the moving column 560, and the installation box 440 has a moving groove for supplying the roller 570 to move; a ball 580, which is arranged on the side of the moving column 560 away from the roller 570, and the ball 580 contacts the oblique guide groove of the connecting disk 480.

[0034] In this embodiment, when there is no natural wind or the natural wind is small, which cannot meet the effective heat dissipation requirement of the distribution box body 100, causing the heat of the distribution box to continuously increase, the heat absorption rod 550 senses the heat in the box and the temperature rises, causing the liquid in the liquid storage pipe 530 to warm up and expand, causing the liquid pressure in the liquid storage pipe 530 to change, thereby pushing the piston 540 in the horizontal pipe to move, the piston 540 moving drives the moving column 560 and the roller 570 to move, and the ball 580 rolls in the inclined guide groove of the connecting disc 480. As the ball 580 moves to the flat area in the inclined guide groove, the connecting disc 480 moves downward and drives the lifting bevel gear 521 to move downward and engage with the fixed bevel gear 520. At this time, the motor 510 is started to drive the fixed bevel gear 520 to rotate, and the fixed bevel gear 520 drives the lifting bevel gear 521 to rotate through meshing transmission, thereby driving the short shaft 460 to rotate, and the short shaft 460 drives the fan blade 470 to rotate to generate strong suction to suck the heat of the distribution box body 100 into the installation box 440 and conduct it. At this time, since the connecting disc 480 moves downward, it will not drive the first connecting piece and the long shaft 420 to rotate.

[0035] In this design, the switching mechanism 500 provides double heat dissipation protection for the distribution box body 100. When there is natural wind, the natural wind energy is preferred for heat dissipation, which is energy-saving and environmentally friendly. When there is no natural wind or the natural wind is not enough to meet the heat dissipation requirement, it can immediately switch to the heat dissipation mode driven by the motor 510 to ensure that the distribution box body 100 is always within the appropriate working temperature range, improving the reliability and stability of the equipment.

[0036] The enhanced heat dissipation outdoor comprehensive distribution box works, the electronic components in the distribution box generate heat, the heat is conducted to the heat exchange plate 130 through the installation strip 140, and the heat absorption fin 220 absorbs the heat in the distribution box body 100. The heat exchange plate 130 and the heat dissipation fin 241 transmit heat to the water tank 210. At this time, if there is natural wind in the outdoor environment, the wind vane 350 can perceive the direction of the incoming wind in real time due to its streamlined structure, and transmit power to the rotating cover 320. The rotating cover 320 rotates on the rotating track 310 of the support table 150, so that the position of the air suction fan 330 corresponds to the direction of the incoming wind. The natural wind impacts the fan blade 410 to rotate, and the output shaft transmits power to the driving bevel gear 431. The driving bevel gear 431 drives the driven bevel gear 432 and the long shaft 420 to rotate. The long shaft 420 transmits power to the short shaft 460 through the cooperation of the first connecting piece, the second connecting piece and the connecting disc 480. The short shaft 460 drives the fan blade 470 to rotate to generate suction, and the air in the front electronic component mounting area in the distribution box body 100 is sucked into the installation box 440. The hot air is guided by the air baffle 450, passes through the ventilation opening of the heat exchange plate 130, and is transported to the rear heat exchange area in the distribution box body 100. The hot air is transmitted to the heat absorption fin 220 by the flow guide cover 260, and the heat absorption fin 220 transmits heat to the cooling liquid in the water tank 210. After the air in the distribution box body 100 is heat-exchanged by the heat absorption fin 220, it returns to the electronic component mounting area through the bottom ventilation of the heat exchange plate 130, thereby achieving preliminary heat dissipation. After the cooling liquid in the water tank 210 absorbs heat, the temperature rises and the density decreases. Under the action of gravity difference and thermal convection, the hot cooling liquid rises to the heat dissipation disc 240 through the liquid lifting pipe 230. The heat dissipation fin 241 on the heat dissipation disc 240 increases the contact area with air. The high-speed rotation of the fan blade 410 generates strong suction and exhaust capacity, sucks the natural wind into the rotating cover 320, and discharges it through another fan 330, thereby forming an orderly airflow. The airflow contacts the heat dissipation fin 241 on the heat dissipation disc 240 to carry away the heat on the heat dissipation fin 241, so that the temperature of the cooling liquid in the heat dissipation disc 240 decreases and the density increases. Under the action of gravity, the cooling liquid returns to the water tank 210 through the liquid return pipe 250, thereby forming a circulating heat dissipation. When there is no natural wind or the natural wind is small, the distribution box cannot meet the heat dissipation demand, and the heat in the box continues to rise. The heat absorption rod 550 senses the heat in the box and the temperature rises, so that the liquid in the liquid storage pipe 530 is heated and expanded. The liquid pressure in the liquid storage pipe 530 changes, pushing the piston 540 in the horizontal pipe to move. The piston 540 drives the moving column 560 and the roller 570 to move, and the ball 580 rolls in the inclined guide groove of the connecting disc 480. When the ball 580 moves to the flat area, the connecting disc 480 moves downward, driving the lifting bevel gear 521 to move downward and engage with the fixed bevel gear 520. At this time, the motor 510 is started to drive the fixed bevel gear 520 to rotate, and the fixed bevel gear 520 drives the lifting bevel gear 521 to rotate, thereby driving the short shaft 460 to rotate. The short shaft 460 drives the fan blade 470 to rotate to generate strong suction.The heat in the distribution box is sucked into the installation box 440 and conducted to the heat absorption fins 220, achieving high-efficiency heat dissipation.
