Description

Technical Field

[0001] This invention relates to the field of hub technology, and more particularly to a modular high and low voltage circuit combination smart hub. Background Technology

[0002] With the rapid development of information technology, electronic devices are increasingly widely used in various fields, and the requirements for their performance and stability are also becoming higher. Modular high- and low-voltage circuit combination intelligent hubs, as an important type of electronic device, undertake key tasks such as data transmission and signal distribution; their operational stability and reliability directly affect the performance of the entire system.

[0003] Hubs generate a significant amount of heat during operation. If this heat cannot be dissipated promptly, the internal temperature of the hub will rise, affecting the performance and lifespan of electronic components and potentially causing equipment malfunction. Traditional hub cooling methods typically employ simple cooling fans to remove heat through air convection. However, this method has several limitations. Firstly, relying solely on air convection has limited cooling efficiency, making it difficult to meet the cooling requirements of high-power, highly integrated hubs. Secondly, in environments with high humidity or dust, traditional cooling methods cannot effectively handle moisture and dust. Moisture can cause short circuits or corrosion, while dust can easily clog heat dissipation channels, further reducing cooling efficiency and affecting the normal operation of the hub.

[0004] Therefore, this application proposes a modular high and low voltage circuit combination intelligent hub. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned technical problems by proposing a modular high and low voltage circuit combination intelligent hub.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A modular high and low voltage circuit combination intelligent hub includes a housing, a top cover is installed on the upper end of the housing, and a hub module is installed inside the housing;

[0008] A thermally conductive rubber plate is installed inside the housing. A cooling fan is installed at one end of the housing, and a dust removal and heat dissipation mechanism is installed at the other end of the housing. The dust removal and heat dissipation mechanism includes an installation box fixed to and connected to the housing. The bottom of the installation box is open, and an air inlet mesh plate is fixed to the inner wall. A support plate is fixed inside the installation box. A dust removal heat exchange cylinder is fixedly connected through the support plate. A dust filter mesh plate rotates at the bottom of the dust removal heat exchange cylinder, and an air outlet mesh plate is fixed at the top. The dust removal heat exchange cylinder contains steel balls, and a serpentine heat exchange tube rotates to agitate and exchange heat with the steel balls. The steel balls agitated by the serpentine heat exchange tube form a three-dimensional filter mesh that works with the dust filter mesh plate to filter the air. A heat exchange channel communicating with the serpentine heat exchange tube is provided inside the thermally conductive rubber plate. Clean water flows in the serpentine heat exchange tube and the heat exchange channel to exchange heat with the hub module and the steel balls. After passing through the dust removal heat exchange cylinder, the air is heated by the steel balls and the serpentine heat exchange tube, and the heated air enters the housing.

[0009] Preferably, the upper end of the serpentine heat exchange tube passes through the air outlet mesh plate and is rotatably connected to it, and the lower end of the serpentine heat exchange tube passes through the dust filter mesh plate and is fixedly connected to it.

[0010] Preferably, the lower end of the serpentine heat exchange tube is rotatably connected to a vertical tube, the bottom of the vertical tube is connected to a bent tube, and the bent tube is connected to the heat exchange channel.

[0011] Preferably, the system further includes a pumping mechanism for conveying clean water into the serpentine heat exchange tube and the heat exchange channel. The pumping mechanism includes a water tank installed at the top of the installation box, a motor installed at the bottom of the water tank, a drive shaft fixed at the output end of the motor, a circular plate fixed at the bottom of the drive shaft, and a connecting rod eccentrically hinged to the bottom of the circular plate. A piston cylinder is installed inside the installation box, and a movable piston is slidably connected inside the piston cylinder. The movable piston is hinged to the connecting rod. The piston cylinder is connected to the water tank through an inlet pipe, and an inlet check valve is installed on the inlet pipe. An outlet pipe is installed on the piston cylinder, and an outlet check valve is installed on the outlet pipe. A connecting pipe is fixed at the upper end of the serpentine heat exchange tube, and the outlet pipe is rotatably connected to the connecting pipe. A return pipe is connected to the heat-conducting rubber plate, and the return pipe is connected to the heat exchange channel and the water tank.

[0012] Preferably, it further includes a transmission mechanism for driving the serpentine heat exchange tube to rotate. The transmission mechanism includes two transmission wheels fixed on the drive shaft and the connecting pipe, and the two transmission wheels are connected by a belt.

[0013] Preferably, a semiconductor cooling chip is installed on the water tank, and a heat sink is installed on the semiconductor cooling chip.

[0014] Preferably, the system further includes a dust removal mechanism, which includes a reciprocating screw rotatably mounted in a mounting box. Both the reciprocating screw and the vertical tube are fixed with bevel gears, which mesh with each other. A sliding block is fitted onto the reciprocating screw, and a U-shaped tube is fixed to the sliding block. A connecting thin tube is fixed to the upper end of the U-shaped tube, with the upper end of the thin tube positioned near the bottom of the dust filter plate without contact between them. An air inlet pipe is connected to the U-shaped tube, and a pressure relief valve is installed on the air inlet pipe. The upper end of the air inlet pipe is positioned above the water surface in the water tank. A collection net is installed through the mounting box, and an exhaust pipe is connected to the collection net. The exhaust pipe is slidably connected inside the U-shaped tube.

[0015] Preferably, a guide rod is fixed to the inner wall of the mounting box, and the guide rod passes through the slider and is slidably connected to it.

[0016] Preferably, an air intake pipe is installed on the piston cylinder, and an air intake check valve is installed on the air intake pipe.

[0017] Preferably, a flexible hose is installed on the air intake pipe, and the flexible hose is connected to a U-shaped pipe.

[0018] Compared with the prior art, the beneficial effects of this invention are as follows:

[0019] 1. The rotating serpentine heat exchange tube agitates the steel balls inside the dust removal heat exchange cylinder, causing the steel balls to form a dynamic three-dimensional filter screen. This three-dimensional filter screen continuously changes shape during rotation, which not only greatly enhances the filtration effect, but also greatly increases the contact area and contact time between the air and the steel balls, which is conducive to the full heat exchange.

[0020] 2. As air passes through the three-dimensional filter formed by the steel balls, it undergoes thorough heat exchange with the steel balls. The steel balls have excellent thermal conductivity, enabling them to quickly absorb heat from the air and rapidly lower its temperature. Simultaneously, the rotating steel balls continuously collide with the surrounding air and other steel balls, further promoting heat transfer and dispersion, improving heat exchange efficiency, and facilitating heat dissipation for the hub module.

[0021] 3. In humid environments, the cooled serpentine heat exchange tubes and steel balls can condense humid air. Water vapor in the humid air quickly condenses into water droplets as it passes through the low-temperature serpentine heat exchange tubes and steel balls, adhering to the steel balls. During rotation, the steel balls, through centrifugal force and collision, expel the water droplets from the system, effectively reducing the amount of moisture entering the housing. This lowers the risk of short circuits or corrosion within the hub module due to excessive humidity, improving the reliability and stability of the hub in humid environments.

[0022] 4. The transmission mechanism drives the serpentine heat exchange tube to rotate, which in turn drives the vertical tube to rotate. The vertical tube, through a bevel gear, drives the reciprocating screw to rotate, causing the slider to move the U-shaped tube and the thin tube back and forth. During the reciprocating motion of the piston cylinder, when the pressure inside the water tank exceeds the threshold of the pressure relief valve, high-speed, high-pressure air is discharged through the air inlet pipe. At the thin tube, a negative pressure is generated according to Bernoulli's principle, which sucks away the dust filtered at the bottom of the dust filter plate and transports it to the exhaust pipe, where it is finally collected by the collection net.

[0023] 5. The agitation of the steel balls causes the dust filter plate to vibrate. Combined with negative pressure cleaning, this can thoroughly remove stubborn dust adhering to the dust filter plate, effectively preventing dust from clogging the heat dissipation channels, ensuring the normal operation of the heat dissipation system, and further improving the stability and reliability of the hub.

[0024] 6. The steel balls are more effective at dust collection when they are wet, thus improving the air filtration effect. When the steel balls are no longer wet, the collision between them can clean and crush the dust on their surface. Combined with the negative pressure adsorption of the fine tube, the dust located at the top of the dust filter plate can be cleaned.

[0025] In summary, this invention enables efficient heat dissipation, air dehumidification, and dust removal for hub modules, ensuring stable and reliable operation of the hub modules. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Reference Figures 1-9 A modular high and low voltage circuit combination smart hub includes a housing 1, a top cover 2 installed on the upper end of the housing 1, and a hub module installed inside the housing 1. The electrical contact pieces used in the hub module are made of gold-nickel alloy or gold-palladium alloy, which have good conductivity. Since the hub module has USB plugs or other plugs with input and output ends, the metal pieces on the plugs are also made of gold-nickel alloy or gold-palladium alloy.

[0038] A heat-conducting rubber plate 5 is installed inside the housing 1. A cooling fan is installed at one end of the housing 1, and a dust removal and heat dissipation mechanism is installed at the other end of the housing 1. The dust removal and heat dissipation mechanism includes a mounting box 4 fixed on the housing 1 and connected to the housing 1. Ventilation slots are provided through the mounting box 4 and the housing 1. A protective cover 3 is provided on the housing 1. The protective cover 3 is located outside the mounting box 4 and has ventilation slots.

[0039] The bottom of the mounting box 4 is open and the inner wall is fixed with an air inlet mesh plate 8. A support plate 11 is fixed inside the mounting box 4. A dust removal heat exchange cylinder 12 is fixedly connected through the support plate 11. A dust filter mesh plate 20 is rotatably mounted at the bottom of the dust removal heat exchange cylinder 12 and an air outlet mesh plate 31 is fixed at the top. The upper end of the serpentine heat exchange tube 41 passes through the air outlet mesh plate 31 and is rotatably connected to it. The lower end of the serpentine heat exchange tube 41 passes through the dust filter mesh plate 20 and is fixedly connected to it.

[0040] The dust removal heat exchange cylinder 12 contains steel balls and is equipped with a serpentine heat exchange tube 41 that rotates to agitate and exchange heat with the steel balls. It also includes a transmission mechanism that drives the serpentine heat exchange tube 41 to rotate. The transmission mechanism includes two transmission wheels 36 fixed on the drive shaft 34 and the connecting pipe 32. The two transmission wheels 36 are connected by a belt 35.

[0041] The steel balls agitated by the serpentine heat exchange tube 41 form a three-dimensional filter screen to filter the air in conjunction with the dust filter plate 20. The heat-conducting rubber plate 5 is provided with a heat exchange channel 7 that communicates with the serpentine heat exchange tube 41. The lower end of the serpentine heat exchange tube 41 is rotatably connected to a vertical tube 23. The bottom of the vertical tube 23 is connected to a bent tube 25, which is connected to the heat exchange channel 7.

[0042] Clean water flows in the serpentine heat exchange tube 41 and heat exchange channel 7 to exchange heat with the hub module and steel balls. Air passes through the dust removal heat exchange cylinder 12 and is then heated by the steel balls and serpentine heat exchange tube 41. The heated air then enters the shell 1.

[0043] It also includes a pumping mechanism for conveying clean water into the serpentine heat exchange tube 41 and the heat exchange channel 7. The pumping mechanism includes a water tank 9 installed at the top of the installation box 4. A semiconductor cooling chip 37 is installed on the water tank 9. A heat sink is installed on the semiconductor cooling chip 37. The semiconductor cooling chip 37 is used to cool and reduce the water in the water tank 9. The heat sink can dissipate heat from the semiconductor cooling chip 37 to ensure its stable operation.

[0044] A motor 33 is installed at the bottom of the water tank 9. A drive shaft 34 is fixed at the output end of the motor 33. A circular plate 38 is fixed at the bottom of the drive shaft 34. A connecting rod 40 is eccentrically hinged to the bottom of the circular plate 38. A piston cylinder 13 is installed inside the mounting box 4. A movable piston 39 is slidably connected inside the piston cylinder 13. The movable piston 39 is hinged to the connecting rod 40. The piston cylinder 13 is connected to the water tank 9 through a water inlet pipe 16. A water inlet check valve 17 is installed on the water inlet pipe 16. The water inlet check valve 17 only allows water in the water inlet pipe 16 to flow into the piston cylinder 13.

[0045] A water outlet pipe 18 is installed on the piston cylinder 13, and a one-way valve 19 is installed on the water outlet pipe 18. The one-way valve 19 only allows water in the piston cylinder 13 to flow into the water outlet pipe 18. A connecting pipe 32 is fixed to the upper end of the serpentine heat exchange tube 41. The water outlet pipe 18 is rotatably connected to the connecting pipe 32. A return pipe 21 is connected to the heat-conducting rubber plate 5. The return pipe 21 is connected to the heat exchange channel 7 and the water tank 9.

[0046] It also includes a dust removal mechanism, which includes a reciprocating screw 27 rotatably installed in the mounting box 4. Both the reciprocating screw 27 and the vertical tube 23 are fixed with bevel gears 24. The two bevel gears 24 mesh with each other. A sliding block 26 is fitted on the reciprocating screw 27 and is connected to it. A guide rod 28 is fixed on the inner wall of the mounting box 4. The guide rod 28 passes through the sliding block 26 and is slidably connected to it to ensure the stable movement of the sliding block 26.

[0047] A U-shaped tube 29 is fixed on the slider 26. A thin tube 22 is fixed to the upper end of the U-shaped tube 29. The upper end of the thin tube 22 is located near the bottom of the dust filter plate 20 and the two do not contact each other. An air inlet pipe 10 is connected to the U-shaped tube 29. A flexible hose is installed on the air inlet pipe 10 and connected to the U-shaped tube 29. A pressure relief valve is installed on the air inlet pipe 10, and the upper end of the air inlet pipe 10 is located above the water surface in the water tank 9. An air intake pipe 14 is installed on the piston cylinder 13. An air intake check valve 15 is installed on the air intake pipe 14. The air intake check valve 15 only allows air to be drawn into the piston cylinder 13 through the air intake pipe 14. The position of the air intake pipe 14 is not limited to the position shown in the figure and can also be in other positions.

[0048] A collection net 6 is installed through the mounting box 4, and an exhaust pipe 30 is connected to the collection net 6. The exhaust pipe 30 is slidably connected inside the U-shaped tube 29, so that the two can move relative to each other.

[0049] The working principle of this invention is as follows: When the hub starts working, the cooling fan starts simultaneously, quickly creating a stable negative pressure environment inside the housing 1. Due to the negative pressure inside the housing 1, external air is drawn in from the opening at the bottom of the mounting box 4 at a relatively uniform and stable flow rate.

[0050] Air first passes through the air inlet mesh plate 8, which can not only effectively intercept larger floating objects in the air, such as paper scraps, but also block some larger insects and other foreign objects to a certain extent, preventing them from entering the installation box 4 and avoiding damage or blockage to the subsequent filtration and heat dissipation components.

[0051] The air, after initial filtration, smoothly enters the dust removal and heat exchange cylinder 12. At this point, the airflow velocity is relatively stable and uniform, providing ideal conditions for subsequent filtration and heat exchange processes. The dust filter plate 20 can effectively filter fine dust and impurities in the air.

[0052] The motor 33 is started, and after starting, it drives the drive shaft 34 to rotate. Under the precise drive of the transmission mechanism, the serpentine heat exchange tube 41 begins to rotate stably and orderly. The rotating serpentine heat exchange tube 41 agitates the steel balls inside the dust removal heat exchange cylinder 12, causing the steel balls to form a dynamic three-dimensional filter screen. This three-dimensional filter screen continuously changes shape during rotation, which not only greatly enhances the filtration effect but also significantly increases the contact area and contact time between the air and the steel balls, which is conducive to the full heat exchange.

[0053] As air passes through the three-dimensional filter formed by steel balls, it undergoes thorough heat exchange with the balls. The steel balls have excellent thermal conductivity, enabling them to rapidly absorb heat from the air and quickly lower its temperature. Simultaneously, the rotating steel balls continuously collide with the surrounding air and other steel balls, further promoting heat transfer and dispersion, thus improving heat exchange efficiency.

[0054] The drive shaft 34, through the cooperation of the circular plate 38, connecting rod 40, and moving piston 39, achieves efficient reciprocating suction of clean water in the piston cylinder 13. When the moving piston 39 moves close to the circular plate 38, a stable negative pressure is formed in the piston cylinder 13. At this time, the inlet check valve 17 opens, and clean water is quickly and smoothly drawn into the piston cylinder 13 from the water tank 9 through the inlet pipe 16.

[0055] When the moving piston 39 moves away from the circular plate 38, the clean water in the piston cylinder 13 is compressed evenly. At this time, the outlet check valve 19 opens, and the clean water enters the serpentine heat exchange tube 41 through the outlet pipe 18 at a certain pressure.

[0056] As the water flows within the serpentine heat exchange tube 41, it undergoes thorough heat exchange with the steel balls and the air. The steel balls efficiently transfer the absorbed heat to the water, raising its temperature. Simultaneously, the water absorbs heat from the air, further lowering the air temperature.

[0057] After heat exchange, the air enters the housing 1 through the ventilation slot, which can effectively dissipate heat from the hub module.

[0058] After cooling, the clean water enters the heat-conducting rubber plate 5 through the bend 25 and heat exchange channel 7. The heat-conducting rubber plate 5 has a special heat-conducting channel and structure inside, which enables the heat in the clean water to be transferred evenly and quickly to the hub module, achieving efficient heat dissipation for the hub module. After cooling, the clean water flows back to the water tank 9 through the return pipe 21, completing a complete clean water cycle. The design of the return pipe 21 takes into account the smooth flow of water back and the prevention of backflow, ensuring that the clean water can smoothly return to the water tank 9.

[0059] When the water temperature in water tank 9 rises, the thermoelectric cooler 37 on water tank 9 begins to operate, cooling the water. The cooling efficiency of the thermoelectric cooler 37 has been optimized and adjusted to quickly lower the water temperature, ensuring effective heat dissipation. The thermoelectric cooler 37 generates heat during operation; the radiator uses a combination of high-efficiency heat dissipation fins and a fan to dissipate heat from the thermoelectric cooler 37 in a timely and effective manner, ensuring stable operation. The fan speed of the radiator automatically adjusts according to the temperature of the thermoelectric cooler 37, achieving a balance between energy saving and efficient heat dissipation.

[0060] If the air humidity is high, the cooled serpentine heat exchange tube 41 and steel balls can condense the humid air. Because the serpentine heat exchange tube 41 and steel balls are at a low temperature, the water vapor in the humid air quickly condenses into water droplets as it passes through, adhering to the steel balls. During the rotation of the steel balls, centrifugal force and collisions accelerate the discharge of the water droplets. The water droplets, along with the movement of the steel balls and gravity, fall into the drainage area at the bottom of the dust removal heat exchange cylinder 12 and are discharged through a dedicated drainage pipe. This dehumidifies the air, reduces the impact on the hub module, and avoids problems such as short circuits or corrosion inside the hub module due to excessive humidity.

[0061] The vertical tube 23 is rotatably connected to the lower end of the serpentine heat exchange tube 41 and rotates along with the serpentine heat exchange tube 41. The rotation of the vertical tube 23 is precisely transmitted to the reciprocating screw 27 via the bevel gear 24. Driven by the bevel gear 24, the reciprocating screw 27 rotates stably, causing the slider 26 on the reciprocating screw 27 to perform reciprocating linear motion under the precise guidance of the guide rod 28, thereby driving the U-shaped tube 29 and the thin tube 22 to move reciprocally. The material and surface treatment of the guide rod 28 ensure the smoothness and stability of the slider 26's movement, reducing friction and wear.

[0062] The movement of slider 26 drives U-shaped tube 29 and thin tube 22 to move horizontally back and forth. During the reciprocating movement of moving piston 39, air is drawn in through air inlet pipe 10, and then the air-water mixture is delivered to serpentine heat exchange tube 41, and finally flows into water tank 9.

[0063] When the pressure inside water tank 9 exceeds the threshold of the pressure relief valve, the valve opens precisely, and air is discharged through the air inlet pipe 10. The high-speed, high-pressure air flows to the U-shaped tube 29. According to Bernoulli's principle, as air passes through the thin tube 22, the air velocity is lower and the pressure is higher at the upper end of the thin tube 22, while the air velocity is higher and the pressure is lower at the lower end. Therefore, a significant pressure difference is formed between the upper and lower ends of the thin tube 22, generating negative pressure at the upper end of the thin tube 22 (Bernoulli's principle).

[0064] In this way, the negative pressure can suck away the dust filtered at the bottom of the dust filter plate 20 and transport it into the exhaust pipe 30. As the thin tube 22 moves back and forth, it can thoroughly clean the dust at the bottom of the dust filter plate 20 without leaving any dead corners.

[0065] Meanwhile, the steel balls are agitated by the serpentine heat exchange tube 41, which causes the dust filter plate 20 to vibrate. This vibration, combined with negative pressure cleaning, can further enhance the cleaning effect on the dust filter plate 20 and completely remove the stubborn dust attached to the dust filter plate 20.

[0066] The steel balls are more effective at dust collection when they are wet, thus improving the air filtration effect. When the steel balls are no longer wet, the collision between them can clean and crush the dust on their surface. Combined with the negative pressure adsorption of the fine tube 22, the dust located on the top of the dust filter plate 20 can be cleaned.

[0067] Finally, the dust is carried by the air through the exhaust pipe 30 to the collection net 6. The collection net 6 is made of special materials and structure, which can effectively intercept the dust and prevent it from re-entering the system, thus achieving efficient cleaning and collection of the dust.

[0068] Through the coordinated operation of the above components, the heat dissipation system of this modular high and low voltage circuit combination smart hub can achieve efficient heat dissipation, air dehumidification, and dust removal for the hub module, ensuring that the hub module can work stably and reliably in various environments.

[0069] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
