Description

Technical Field

[0001] This invention relates to the field of distribution box technology, specifically to a biomimetic fin heat dissipation device and its application in distribution boxes. Background Technology

[0002] As the core carrier of electrical equipment for power distribution, control, and protection in power systems, distribution boxes are widely used in dusty, high-temperature, and complex environments such as outdoor and industrial settings. Their operational stability directly affects the safe and reliable operation of the power system. However, existing distribution boxes currently suffer from two obvious and prominent drawbacks in practical use, severely impacting their performance and lifespan. First, their heat dissipation efficiency is low. Existing distribution boxes mostly use ordinary flat heat sinks combined with simple fans, resulting in limited heat exchange area and slow heat conduction. This easily leads to internal heat accumulation, causing electrical components exposed to high temperatures for extended periods to age, short-circuit, and other faults, failing to meet the heat dissipation requirements of high-power equipment. Second, there is a significant conflict between dust prevention and cleaning. To improve protection levels, existing distribution boxes typically have protective mesh installed at the air inlets. However, after long-term use, these meshes accumulate a large amount of dust, blocking the air intake and further reducing heat dissipation efficiency. Furthermore, existing equipment lacks automatic cleaning functions, requiring regular manual disassembly and cleaning, which is not only cumbersome and costly to maintain but also poses significant safety hazards when cleaning outdoors or at heights. In view of the shortcomings of the existing equipment, the present invention proposes a biomimetic fin heat dissipation device and its application in a power distribution box to solve the deficiencies of the prior art. Summary of the Invention

[0003] To address the above problems, this invention provides a biomimetic fin heat dissipation device and its application in a power distribution box.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a biomimetic fin heat dissipation device and its application in a power distribution box, comprising a power distribution box, wherein the power distribution box is provided with an air inlet and an air outlet, an air duct is installed inside the power distribution box, the air duct connects the air inlet and the air outlet, and a heat dissipation component is installed at the air inlet; The heat dissipation component includes multiple parallel bionic fins with gaps between each pair of fins. A heat pipe is connected to each fin and passes through it. An outer frame is provided around each fin, and a micro motor is located at the bottom of the frame. A protective net is installed at the front end of each fin. Two symmetrical reciprocating components are mounted on each fin, and a cleaning component is connected between them. The cleaning component is located on the outer surface of the protective net, and a reversing component is installed at the top of the cleaning component.

[0005] Preferably, the reciprocating assembly includes two symmetrically fixed columns, which are fixed to the outer frame. A reciprocating lead screw is rotatably connected between the two fixed columns, and a slider is drivenly connected to the reciprocating lead screw. The cleaning assembly is rotatably connected to the slider, and a rack is fixedly connected to the outer side of the fixed columns.

[0006] Preferably, the rack has toothless sections at both ends, and two symmetrical reversing push rods are fixed on the rack.

[0007] Preferably, the reversing assembly includes a transmission gear, which is fixedly connected to the cleaning assembly. A fixing member is fixedly connected to the transmission gear, and the fixing member includes an inner cylinder and an outer cylinder. Multiple fan blades are arranged along the circumference of the inner side of the fixing member.

[0008] Preferably, a rotating shaft is provided in the center of the fan blade, and the fan blade is rotatably connected to the inner and outer cylinders of the fixing member through the rotating shaft. The rotating shaft passes through the inner cylinder and is connected to a reversing gear. The inner cylinder of the fixing member is rotatably connected to a reversing column. The reversing column is driven by the reversing gear, and a reversing rod is fixedly connected to the reversing column.

[0009] Preferably, the cleaning assembly includes a hollow cylindrical tube, the outer wall of which is provided with a plurality of suction holes along its circumference, and a cleaning brush is provided between each pair of suction holes.

[0010] Preferably, a slot is provided between each pair of suction holes, and a snap-fit ​​component is snapped into the slot, which is fixedly connected to the cleaning brush.

[0011] Preferably, the micro motor is connected to the two reciprocating lead screws, the two reciprocating lead screws rotate synchronously, and a fan is provided at the rear end of the outer frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The heat generated by the electrical components inside the distribution box is quickly conducted through heat pipes. Combined with biomimetic fins designed to mimic the efficient heat dissipation structure of biological organisms, the heat exchange area is greatly increased, solving the problems of low heat exchange efficiency and heat accumulation in traditional distribution box heat sinks. The fan at the rear of the outer frame and the air duct inside the distribution box form an efficient airflow circulation. The cool air can fully contact the biomimetic fins to remove heat, and the hot air is quickly discharged, continuously maintaining a low temperature environment inside the distribution box. This effectively avoids electrical components from aging and short circuits due to high temperature, ensuring stable operation of the equipment. The heat dissipation efficiency is significantly improved compared to traditional structures.

[0013] 2. The front-end protective net adopts a high-density dustproof structure, which can effectively block the intrusion of external dust and debris, improve the protection level of the distribution box, and protect the cleanliness and safety of internal components. At the same time, it is equipped with a reciprocating component, a cleaning component, and a reversing component. The protective net can be thoroughly cleaned without manual intervention. The reciprocating component drives the cleaning component to move back and forth and rotate. The cleaning brush cleans dust without dead corners. The reversing component adaptively adjusts the direction of the fan blades to ensure that dust is effectively sucked in and discharged by the hollow round tube, avoiding secondary dust. This solves the problem of dust accumulation on the protective net blocking the air duct and affecting heat dissipation.

[0014] 3. The sweeping brush adopts a snap-fit ​​design with slots and connectors, which can be quickly disassembled and replaced after wear without disassembling the entire sweeping assembly, making operation simple; the micro motor drives two reciprocating lead screws to rotate synchronously, ensuring that the sweeping assembly runs smoothly without deviation or jamming. All parts fit together tightly, and the outer frame provides solid support and protection for the internal components, improving the device's impact resistance, adapting to harsh outdoor environments, reducing the probability of component damage, and lowering maintenance frequency and costs.

[0017] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0018] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A biomimetic finned heat dissipation device and its application in a distribution box are disclosed. The distribution box 1 serves as the core carrier for power distribution, control, and protection of electrical equipment in a power system. It is widely used in dusty, high-temperature, and complex environments such as outdoor and industrial settings. The distribution box 1 has air inlets and outlets rationally designed on its surface, solving the problems of poor heat dissipation and internal heat accumulation caused by unreasonable air duct design in traditional distribution boxes. An air duct 11 is installed inside the distribution box 1, which closely connects the air inlet and outlet to form an efficient air circulation channel, accelerating heat dissipation and preventing the electrical components inside the distribution box 1 from aging or short-circuiting due to high temperatures. A heat dissipation component 2 is installed at the air inlet, providing dual protection for the core heat dissipation and protection of the distribution box 1.

[0019] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5The heat dissipation component 2 includes multiple parallel biomimetic fins 21. These fins mimic the efficient heat dissipation structure of biological components, significantly increasing the heat exchange area and solving the problems of low heat exchange efficiency and inability to quickly dissipate heat associated with traditional heat sinks. Uniform gaps are provided between each pair of fins to facilitate smooth airflow, ensuring uniform heat dissipation and preventing localized overheating that could damage components. Heat-conducting pipes 22 are fixedly connected to each biomimetic fin 21, passing through it and possessing high thermal conductivity. These pipes quickly transfer heat from inside the distribution box 1 to the surface of the fins 21, solving the problem of heat accumulation inside the distribution box 1. An outer frame 23 is provided around each biomimetic fin 21, which serves to fix and support the fins 21, heat-conducting pipes 22, and other components, improving the overall structural stability and impact resistance, and preventing damage to internal components from harsh outdoor environments. A micro motor is located at the bottom of the outer frame 23. 6. As the power source for the entire cleaning and reversing system, it provides stable and continuous power, solving the problems of traditional equipment requiring manual dust removal, cumbersome maintenance, and low efficiency. The front end of the bionic fin 21 is equipped with a protective net 7. The protective net 7 adopts a high-density dustproof structure, which can effectively block external dust and debris from entering the power distribution box 1, improving the protection level of the power distribution box 1 and solving the problem of short circuits and aging of electrical components caused by dust intrusion, while not affecting the air intake efficiency. Two symmetrical reciprocating components 3 are installed on the bionic fin 21. A cleaning component 4 is connected between the two reciprocating components 3. The cleaning component 4 is closely attached to the outer surface of the protective net 7, which can perform comprehensive and thorough cleaning of the protective net 7, solving the problem of dust accumulation and air duct blockage of the protective net 7 after long-term use. A reversing component 5 is installed at the upper end of the cleaning component 4, which can adaptively adjust the blowing direction to ensure effective dust collection during the cleaning process, avoid secondary dust generation, and further improve the dust removal effect.

[0020] Please see Figure 3 , Figure 4 and Figure 5The reciprocating assembly 3 includes two symmetrically positioned fixed posts 31, which are firmly fixed to the outer frame 23. These posts provide stable support for the reciprocating lead screw 32, ensuring that the lead screw 32 does not wobble or deviate during rotation, thus solving the problems of component misalignment and wear during power transmission. The reciprocating lead screw 32 is rotatably connected between the two fixed posts 31. A slider 35 is driven onto the reciprocating lead screw 32, which converts its rotational motion into the reciprocating linear motion of the slider 35, thus facilitating the movement of the cleaning assembly 4. The rotating component provides stable power, solving the problems of discontinuous movement and incomplete cleaning in traditional cleaning structures. The cleaning component 4 is rotatably connected to the slider 35, which can both follow the slider 35 in reciprocating movement and rotate on its own, achieving all-round cleaning. A rack 33 is fixedly connected to the outside of the fixed column 31. The rack 33 meshes with the transmission gear 51 in the reversing component 5, providing power for the rotation of the cleaning component 4. This solves the problem of cleaning dead spots caused by the cleaning component 4 being able to only move but not rotate, thus improving cleaning efficiency.

[0021] Please see Figure 4 and Figure 5 The rack 33 has toothless portions 331 at both ends. These toothless portions serve as buffers and transition points, preventing jamming and impact when the transmission gear 51 disengages from the rack 33, thus protecting the components from damage. They also provide ample space for adjusting the direction of the reversing assembly 5, solving the problems of jamming and component wear during reciprocating motion. Two symmetrical reversing push rods 34 are fixed on the rack 33. These push rods 34 precisely cooperate with the reversing rods 52 in the reversing assembly 5. When the cleaning assembly 4 moves to both ends of the rack 33, the push rods 34 rotate the reversing rods 52 through contact, thereby adjusting the direction of the fan blades 54. This ensures that the fan blades 54 are always in an effective blowing state, solving the problems of misalignment of the fan blades 54 and dust collection failure during reciprocating motion.

[0022] Please see Figure 4 , Figure 5 and Figure 6The reversing component 5 includes a transmission gear 51, which is fixedly connected to the cleaning component 4. When the transmission gear 51 meshes with the rack 33, it can drive the cleaning component 4 to rotate while it moves, thereby realizing the rotational cleaning of the cleaning brush 43 and further improving the thoroughness of cleaning. A fixing member 53 is fixedly connected to the transmission gear 51. The fixing member 53 includes an inner cylinder and an outer cylinder. The structure is compact and provides a stable installation space and support for components such as the fan blades 54 and the reversing gear 55, ensuring the coordinated operation of each component. Multiple fan blades 54 are evenly arranged along the circumference of the inner side of the fixing member 53. When the fan blades 54 rotate, they can generate directional wind force, creating a negative pressure inside the cleaning component 4, which quickly sucks in the swept dust, solving the problem of dust that cannot be collected after cleaning and is prone to secondary dust. At the same time, it helps to accelerate air circulation and improve the heat dissipation effect.

[0023] Please see Figure 5 and Figure 6 A rotating shaft is provided in the center of the fan blade 54. The fan blade 54 is flexibly rotatably connected to the inner and outer cylinders of the fixing member 53 through the rotating shaft, ensuring that the fan blade 54 can freely adjust its direction to adapt to different reciprocating motion directions. A reversing gear 55 is fixedly connected to the rotating shaft through the inner cylinder. A reversing column 56 is rotatably connected to the inner cylinder of the fixing member 53. The reversing column 56 and the reversing gear 55 are precisely connected to transmit the rotational motion of the reversing column 56 to the fan blade 54, realizing the synchronous adjustment of the direction of multiple fan blades 54 and ensuring the consistency of the dust collection effect. A reversing rod 52 is fixedly connected to the reversing column 56. The reversing rod 52 can drive the reversing column 56 to rotate under the action of the reversing top rod 34, and then drive the fan blade 54 to adjust its direction through the reversing gear 55. This ensures that no matter which direction the cleaning component 4 moves, the fan blade 54 always blows air into the cleaning component 4, ensuring the continuous and effective dust collection function.

[0024] Please see Figure 5 , Figure 6 and Figure 7The cleaning component 4 includes a hollow cylindrical tube 41, which serves as a dedicated channel for dust collection and discharge. Its hollow structure and good sealing prevent dust leakage, while its smooth inner wall reduces dust adhesion and facilitates rapid dust discharge. Multiple suction holes 42 are evenly distributed along the circumference of the outer wall of the hollow cylindrical tube 41. The diameter of each suction hole 42 is adapted to the size of dust particles, allowing for rapid suction of the swept dust into the tube, solving the problems of inconvenient dust collection and easy dust scattering. A cleaning brush 43 is installed between each pair of suction holes 42. The cleaning brush 43 is made of a flexible and wear-resistant material, enabling thorough cleaning. The cleaning brush removes dust and stains from the surface of the protective net 7 without scratching it, thus extending its service life. This solves the problems of traditional cleaning brushes that easily damage the protective net and fail to clean thoroughly. The suction holes 42 are connected in pairs by slots 411, with snap-fit ​​parts 431 tightly engaged within each slot. These snap-fit ​​parts 431 are fixedly connected to the cleaning brush 43, facilitating disassembly, replacement, and maintenance. When the cleaning brush 43 wears out, it can be quickly replaced without disassembling the entire cleaning assembly 4, reducing maintenance costs and solving the problems of inconvenient fixed installation and maintenance of traditional cleaning brushes.

[0025] Please see Figure 1 and Figure 2 The micro motor 6 is connected to the two reciprocating lead screws 32 through a synchronous transmission design, which ensures that the two reciprocating lead screws 32 rotate at the same speed and in sync, so that the cleaning component 4 is subjected to uniform force at both ends and runs smoothly, avoiding problems such as deviation and jamming, and ensuring the stability of the cleaning and vacuuming process. A fan is provided at the rear end of the outer frame 23. The fan can actively draw in cool air from the outside to quickly cool down the bionic fins 21. At the same time, the heat on the bionic fins 21 is quickly discharged to the outside of the power distribution box 1 through the air duct 11, forming a closed-loop collaborative system of "heat conduction-heat dissipation-dust cleaning-vacuuming".

[0026] In summary, the heat pipe 22 rapidly conducts heat from inside the distribution box 1 to the bionic fins 21, utilizing the large surface area of ​​the bionic fins 21 to achieve rapid heat dissipation. Combined with the airflow circulation of the fan and air duct 11, this effectively solves the problems of low heat dissipation efficiency and high internal temperature in traditional distribution boxes, ensuring stable operation of electrical components. The protective net 7 provides high-level dust protection, blocking dust intrusion. The reciprocating component 3 drives the cleaning component 4 to move back and forth and rotate, achieving comprehensive and thorough cleaning of the protective net 7. The reversing component 5 adaptively adjusts the direction of the fan blades 54, ensuring that dust is effectively sucked into the hollow round tube 41 and discharged, completely solving the problem of dust accumulation and blockage in the protective net 7 and the need for manual cleaning, thus reducing maintenance costs. All components are integrated into the outer frame 23, with a compact structure that fits the air inlet space of the distribution box 1. It can be installed without additional modifications, balancing high protection level and efficient heat dissipation, improving the service life and environmental adaptability of the distribution box 1, and can be stably applied in dusty, high-temperature, and complex outdoor and industrial environments.

[0027] When using this invention: First, the distribution box 1 is started. The heat generated by the internal electrical components is quickly conducted to the surface of the bionic fins 21 through the heat pipe 22. At the same time, the fan at the rear of the outer frame 23 starts simultaneously, actively drawing in cool air from the outside. The cool air passes through the gaps between the bionic fins 21, making full contact with the fins and quickly carrying away the surface heat. The heated air is then discharged from the air outlet of the distribution box 1 through the air duct 11, achieving continuous and efficient heat dissipation and preventing the internal high temperature from affecting the operation of the electrical components. During the process of the fan drawing in cool air, the protective net 7 at the front end filters the cool air, effectively preventing external dust and debris from entering the distribution box 1, ensuring the cleanliness and safety of the internal components.

[0028] As the device continues to operate, dust gradually accumulates on the surface of the protective net 7, leading to a decrease in air intake efficiency and affecting heat dissipation. At this time, the micro motor 6 at the bottom of the outer frame 23 is activated. The micro motor 6 drives the two reciprocating lead screws 32 to rotate synchronously. The reciprocating lead screws 32 convert the rotational motion into the reciprocating linear motion of the slider 35. The slider 35 drives the cleaning component 4 to move back and forth along the surface of the protective net 7. At the same time, the transmission gear 51 at the upper end of the cleaning component 4 meshes with the rack 33, causing the cleaning component 4 to rotate as it moves, so that the cleaning brush 43 on the hollow round tube 41 rotates in all directions to clean the dust on the surface of the protective net 7, ensuring no cleaning dead corners.

[0029] During the cleaning process, the reversing assembly 5 works synchronously, and the fan blades 54 inside the fixing part 53 rotate continuously, generating directional airflow that blows into the hollow tube 41, creating negative pressure inside the tube. The dust swept down by the cleaning brush 43 is sucked into the tube through the suction holes 42 on the outer wall of the hollow tube 41 and finally discharged through the lower end of the hollow tube 41, preventing secondary dust re-entrainment. When the cleaning assembly 4 moves to both ends of the rack 33, the transmission gear 51 enters the toothless part 331, and the cleaning assembly 4 stops rotating. At this time, the reversing rod 52 abuts against the reversing push rod 34 on the rack 33. Under the force of the continuous movement of the slider 35, the reversing push rod 34 pushes the reversing rod 52 to rotate. The reversing rod 52 drives the reversing column 56 to rotate. The reversing column 56 drives the fan blades 54 to adjust their direction synchronously through the reversing gear 55, ensuring that the fan blades 54 always blow air into the hollow tube 41, ensuring the continuous and effective dust collection function.

[0030] After the dust on the surface of the protective net 7 is cleaned, the micro motor 6 can be turned off, the cleaning component 4 stops working, and the fan continues to run to maintain normal heat dissipation of the power distribution box 1. If the cleaning brush 43 is worn, it can be quickly disassembled and replaced through the snap-fit ​​structure of the slot 411 and the snap-fit ​​part 431 without disassembling the entire cleaning component 4, making maintenance convenient. Throughout the entire process, the components work together to achieve a closed-loop operation of "heat dissipation-dust prevention-dust cleaning-dust suction", requiring no frequent manual intervention, greatly reducing operation and maintenance costs, and ensuring long-term stable operation of the device.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
