Description

Technical Field

[0001] The present invention relates to the technical field of distribution boxes, and particularly to an intelligent temperature-controlled heat dissipation distribution box. Background Art

[0002] In the power system, as the core equipment for power distribution, the heat dissipation performance of the distribution box directly affects the operation stability and service life. When the traditional distribution box adopts the air-cooling scheme, it relies on forced convection of the fan, and it is easy for the heat dissipation efficiency to decrease due to dust clogging the filter screen. Moreover, the long-term operation of the fan has the risk of mechanical failures (such as bearing wear and motor burnout), with high maintenance costs, and it cannot cope with high power density scenarios, easily causing local hot spots, leading to the aging of electrical components or even fires. For the liquid-cooling scheme, it mostly adopts fixed-flow pumping, which cannot dynamically adjust according to the real-time temperature, may lead to "over-cooling" or "insufficient heat dissipation", with significant energy consumption waste, and the system integration degree is low. It requires additional configuration of temperature control valves, sensors, and electronic control units, with a complex structure and high cost. Especially in outdoor or harsh environments, electronic components are easily damaged by electromagnetic interference or moisture. Therefore, it is necessary to design an intelligent temperature-controlled heat dissipation distribution box to meet the heat dissipation requirements of high power outdoors.

Through holes communicating with the inside of the protective shell are opened on the hollow bottom plate.

[0007] Preferably, heat exchange fins are connected to the outer side of the heat exchange tube. The upper end of the heat exchange tube passes through the water storage tank and is located at the inner bottom of the water storage tank. A movable frame is arranged at the top of the water storage tank. A positioning tube is fixedly connected to the movable frame.

The lower end of the positioning tube is sleeved on the outer side of the heat exchange tube. An inlet communicating with the water storage tank is arranged at the upper part of the positioning tube.

[0008] Preferably, a thermal expansion bag is connected between the middle part of the movable frame and the water storage tank.

[0009] Preferably, vertical grooves corresponding to the back plate are arranged on the inner side of the cabinet body. Both sides of the back plate are respectively slidably connected to the vertical grooves. The back plate is connected to the inner bottom of the cabinet body through a gas spring rod.

[0010] Preferably, the return water pipe vertically passes through the water supply tank.

[0013] For the intelligent temperature-controlled heat dissipation distribution box described in the present invention, when the heat-expanded fluid in the heat conduction seat expands due to heat, it drives the transmission rack to move, thereby controlling the opening degree of the regulating valve, and automatically controlling the heat dissipation effect of the corresponding cabinet body; For the intelligent temperature-controlled heat dissipation distribution box described in the present invention, as the number of electrical equipment on the back plate increases and the weight of the back plate increases, the automatic downward movement can also drive the transmission rack to move downward, thereby further adjusting the opening degree of the regulating valve.

After the lower end of the positioning pipe is separated from the heat exchange pipe, the water in the water storage tank will flow downward through the heat exchange pipe, so as to ensure the heat dissipation effect of the combined distribution box in a short time and realize the emergency cooling work; when the movable frame moves upward, it pulls the steel cable upward, thereby driving the sealing plug to move upward to squeeze the sealing ring, driving the movable pipe to move upward to be squeezed against the limiting ring. At this time, the sealing plug cooperates with the sealing ring and the limiting ring to block the return water pipe; after the movable ring moves upward, the water return port is opened, and the water in the water supply tank can enter the lower part of the return water pipe through the water return port, further facilitating the return of the water in the water storage tank to the ground.

[0017] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0018] As an embodiment of the present invention, as Figures 1 to 8 shown, an intelligent temperature-controlled heat dissipation distribution box of the present invention includes a water storage tank 1, a combined distribution box 2, and a water supply tank 3 arranged from top to bottom. The combined distribution box 2 includes cabinets 4 distributed circumferentially. The bottoms of the cabinets 4 are all connected to a hollow bottom plate 5. The hollow bottom plate 5 is communicated with the water supply tank 3 through a regulating valve 6. The water supply tank 3 is connected to the groundwater through a water pump 7. Heat exchange tubes 8 are arranged at the corners of the cabinets 4. The lower ends of the heat exchange tubes 8 are communicated with the hollow bottom plate 5, and the upper ends of the heat exchange tubes 8 are communicated with the water storage tank 1. The water storage tank 1 is connected to the ground through a return pipe 9.

[0019] During use, the water supply tank 3 extracts groundwater through the water pump 7. After the flow rate is controlled by the regulating valve 6, it flows into the heat exchange tubes 8 in the cabinets 4 through the hollow bottom plate 5. After absorbing the heat generated by the operation of the distribution box, the heated water flows through the heat exchange tubes 8 into the water storage tank 1, and finally returns to the ground through the return pipe 9, reducing water resource waste and effectively coping with high-temperature environments.

[0020] It should be noted that the water storage tank 1 and the water supply tank 3 need to be made of corrosion-resistant materials (such as 304 stainless steel or engineering plastic PP), and the inner walls of the pipes in contact with the groundwater need to be rust-proof treated (such as coated with epoxy resin); the hollow bottom plate 5 needs to have sufficient pressure-bearing capacity (it is recommended to use aluminum alloy with a thickness ≥ 5mm) to prevent deformation due to long-term water flow impact.

[0021] In order to facilitate the control of the regulating valve 6, as an embodiment of the present invention, a vertically arranged back plate 10 is installed inside the cabinet 4. A heat conduction seat 11 is installed on the back of the cabinet 4. The heat conduction seat 11 passes through the cabinet 4 and is connected to the back plate 10. A piston cavity 12 with an opening downward and filled with a thermally expandable fluid is provided in the heat conduction seat 11. A piston 13 is slidably connected in the piston cavity 12. A piston rod 14 and a transmission rack 15 are sequentially connected to the lower part of the piston 13. The valve stem of the regulating valve 6 is connected to an adjusting gear 16 that meshes with the transmission rack 15. It should be added that the side of each group of cabinets 4 is hinged with a cabinet door 38 through a hinge, and the cabinet door 38 is in a closed state during use.

[0022] During use, when the temperature of the cabinet 4 rises, the fluid expands and pushes the piston 13 downward. The piston rod 14 drives the transmission rack 15. The transmission rack 15 meshes with the adjusting gear 16 of the regulating valve 6, driving the valve stem to rotate, increasing the opening of the regulating valve 6, increasing the water supply flow rate, and enhancing the heat dissipation effect inside the corresponding cabinet 4.

[0023] Among them, the thermally expandable fluid can be paraffin.

[0024] In order to improve the heat dissipation effect inside the cabinet body 4, as an embodiment of the present invention, a protective shell 17 is installed on the upper part of the hollow bottom plate 5. The middle part of the protective shell 17 is rotatably connected to a rotating shaft 18. The upper end of the rotating shaft 18 is connected to a paddle 19. The lower part of the rotating shaft 18 is a hollow structure and is connected to a rotary joint 40. The rotary joint 40 is communicated with a regulating valve 6 through a pipeline penetrating the hollow bottom plate 5. The side surface of the lower part of the rotating shaft 18 is communicated with a circumferentially distributed nozzle 20. A through hole 34 communicating with the inside of the protective shell 17 is opened on the hollow bottom plate 5.

[0025] During use, water flows through the rotary joint 40 and enters the hollow structure of the rotating shaft 18, and is ejected from the side nozzle 20 at high speed, pushing the paddle 19 to rotate. The paddle 19 pushes the air at the bottom of the cabinet body 4 to move rapidly upward, thereby promoting the rapid flow of the air inside the cabinet body 4, so as to better contact with the heat exchange tube 8, thereby improving the heat dissipation effect inside the cabinet body 4; at the same time, it can also address the problem that the heat dissipation efficiency is difficult to meet the rapid temperature rise of local components.

[0026] It should be noted that, in order to improve the service life of the equipment, the groundwater needs to be filtered (the filter screen accuracy ≤ 100 meshes) to prevent sediment from entering the nozzle 20 or the through hole 34 and causing blockage. A filtering facility can be set at the water inlet position of the water pump 7.

[0027] In order to facilitate the water body of the heat exchange tube 8 to enter the water storage tank 1, as an embodiment of the present invention, heat exchange fins 21 are connected to the outside of the heat exchange tube 8. The upper end of the heat exchange tube 8 passes through the water storage tank 1 and is located at the inner bottom of the water storage tank 1. A movable frame 22 is arranged at the top of the water storage tank 1. A positioning tube 23 is fixedly connected to the movable frame 22. The lower end of the positioning tube 23 passes through the water storage tank 1 and is slidably connected to the water storage tank 1. The lower end of the positioning tube 23 is sleeved on the outside of the heat exchange tube 8. An inlet 39 communicating with the water storage tank 1 is provided on the upper part of the positioning tube 23.

[0028] During use, in the initial state, the positioning tube 23 is sleeved on the heat exchange tube 8. The water body discharged upward by the heat exchange tube 8 enters the positioning tube 23 and is discharged through the inlet 39 of the positioning tube 23 and falls into the water storage tank 1, thereby preventing the water body in the water storage tank 1 from reversely entering the heat exchange tube 8 through the inlet 39; When the water pump 7 is not working, the movable frame 22 can be lifted upward, thereby pulling all the positioning tubes 23 to move upward. After the lower end of the positioning tube 23 is separated from the heat exchange tube 8, the water body in the water storage tank 1 will flow downward through the heat exchange tube 8, thereby ensuring the heat dissipation effect on the combined distribution box 2 in a short time and realizing emergency cooling work.

[0029] In order to facilitate the automatic driving of the movable frame 22 to move upward, as an embodiment of the present invention, a thermal expansion bag 24 is connected between the middle part of the movable frame 22 and the water storage tank 1.

[0030] During use, if the water pump 7 malfunctions, it is difficult to ensure the water guiding and cooling effect, and the temperature inside the combined water storage tank 1 is too high. The thermal expansion bag 24 expands enough to push the movable frame 22 upward, thereby automatically pulling the positioning pipe 23 upward, causing the water in the water storage tank 1 to move downward through the heat exchange pipe 8 to achieve heat dissipation inside the cabinet body 4.

[0031] It should be noted that the thermal expansion bag 24 of the present invention can be replaced with other thermal expansion structures or with an electric control device to achieve automatic control of the movable frame 22. For example, the automatic lifting of the movable frame can be achieved through an electric telescopic rod cooperating with a temperature detection system.

[0032] To facilitate pre-controlling the state of the regulating valve 6 according to the state of the electrical equipment installed on the back panel 10, as an embodiment of the present invention, a vertical groove 25 corresponding to the back panel 10 is provided inside the cabinet body 4. The two sides of the back panel 10 are respectively slidably connected to the vertical groove 25. The back panel 10 is connected to the inner bottom of the cabinet body 4 through a gas spring rod 26. A slot 35 corresponding to the heat conduction seat 11 is provided on the back of the cabinet body 4, and the heat conduction seat 11 is connected to the inner wall of the slot 35 through a sealing gasket 27.

[0033] During use, as the number of electrical equipment installed on the back panel 10 increases, the weight of the back panel 10 increases, thereby directly driving the heat conduction seat 11 to move downward, driving the transmission rack 15 to move downward and driving the adjustment gear 16 to rotate, further increasing the opening degree of the regulating valve 6. In this way, the opening degree of the regulating valve 6 can be automatically controlled according to the number of electrical equipment installed on the back panel 10. The heat conduction seat 11 is sealed with the slot 35 of the cabinet body 4 through the sealing gasket 27 to prevent dust and water vapor from entering the cabinet body 4, and at the same time ensure effective heat conduction to the piston chamber 12.

[0034] To facilitate controlling the flow direction of the water in the water storage tank 1 to meet the use in case of emergency, as an embodiment of the present invention, the return pipe 9 vertically passes through the water supply tank 3. A return water port 36 communicating with the water supply tank 3 is provided on the side of the return pipe 9. An activity pipe 28 is hermetically and slidably connected inside the return pipe 9. A supporting ring 29 is connected to the inner wall of the return pipe 9. When the activity pipe 28 is pressed against the supporting ring 29, the return water port 36 is closed. The upper part inside the activity pipe 28 is connected with a sealing ring 30. A sealing plug 31 is arranged below the inner side of the sealing ring 30. The upper end of the sealing plug 31 is connected to the movable frame 22 through a steel cable 32. The steel cable 32 passes through the water storage tank 1. A limiting ring 37 fixedly connected to the inner wall of the return pipe 9 is arranged above the sealing ring 30. It should be noted that the contact surface between the lower end surface of the activity pipe 28 and the supporting ring 29 needs to be ground and polished to improve the sealing performance.

[0035] During use, when the movable frame 22 moves upward, it pulls the steel cable 32 upward, thereby driving the sealing plug 31 upward to squeeze the sealing ring 30, and driving the movable pipe 28 upward to be squeezed against the limit ring 37. At this time, the sealing plug 31 cooperates with the sealing ring 30 and the limit ring 37 to block the return water pipe 9; after the movable ring moves upward, the water return port 36 is opened, and the water body in the water supply tank 3 can enter the lower part of the return water pipe 9 through the water return port 36. When the movable frame 22 moves upward, it pulls all the positioning pipes 23 upward. After the lower end of the positioning pipe 23 is separated from the heat exchange pipe 8, the water body in the water storage tank 1 will flow downward through the heat exchange pipe 8 into the hollow bottom plate 5, and then enter the protective shell 17, and pass through the nozzle 20, the rotary joint 40, and the regulating valve 6 into the water supply tank 3, and then flow back to the ground through the return water pipe 9, so as to ensure the heat dissipation effect of the combined distribution box 2 in a short time and realize the emergency cooling work.

[0036] In order to facilitate the cooling treatment of the water body in the water storage tank 1, as an embodiment of the present invention, heat dissipation fins 33 are connected to the side of the water storage tank 1.

[0037] During use, the heat dissipation fins 33 can realize the heat dissipation treatment of the water body in the water storage tank 1, so that when the water body in the water storage tank 1 reversely enters the heat exchange pipe 8, it can still play a certain heat dissipation effect on the heat exchange pipe 8.

[0038] The working principle of the present invention is as follows: During normal operation, the water supply tank 3 pumps groundwater through the water pump 7. After the flow rate is controlled by the regulating valve 6, it flows into the hollow bottom plate 5 at the bottom of the cabinet body 4; the cold water enters the heat exchange pipe 8 at the corner of the cabinet body 4 through the hollow bottom plate 5, absorbs the heat generated by the operation of the distribution box, and the water temperature rises; the heated water flows upward along the heat exchange pipe 8 to the water storage tank 1, releases heat through the heat dissipation fins 33 on the side of the water storage tank 1, and finally flows back to the ground through the return water pipe 9 to form a closed-loop cycle. Among them, when the internal temperature of the cabinet body 4 rises, the thermal expansion fluid in the heat conduction seat 11 expands, pushing the piston 13 downward, driving the transmission rack 15 through the piston 13 rod, and meshing with the adjusting gear 16 to increase the opening of the regulating valve 6, increasing the water supply flow rate and strengthening the heat dissipation; moreover, when the number of electrical equipment installed on the back panel 10 increases, the weight of the back panel 10 increases, and the heat conduction seat 11 is pushed downward through the air spring rod 26 to adjust the opening of the regulating valve 6 in advance to adapt to higher heat dissipation requirements; in the protective shell 17 above the hollow bottom plate 5, the water flows into the hollow structure of the rotating shaft 18 through the rotary joint 40 and is sprayed out at high speed from the nozzle 20, pushing the paddle 19 to rotate, accelerating the upward flow of the air at the bottom of the cabinet body 4, and promoting the heat exchange between the air and the heat exchange pipe 8 to cope with the problem of rapid temperature rise of local components.

[0039] The positioning pipe 23 is sleeved on the upper end of the heat exchange pipe 8, and the heated water flow enters the water storage tank 1 through the water inlet 39 of the positioning pipe 23, preventing the water body in the water storage tank 1 from flowing reversely into the heat exchange pipe 8.

[0040]

[0040] In the emergency state of the failure of the water pump 7, the temperature in the water storage tank 1 rises, causing the thermal expansion bag 24 to expand, pushing the movable frame 22 upward. The positioning tube 23 is disengaged from the heat exchange tube 8, and the water in the water storage tank 1 flows reversely into the cabinet body 4 along the heat exchange tube 8 under the action of gravity, and is quickly dissipated through structures such as the hollow bottom plate 5 and the nozzle 20; At the same time, the movable frame 22 moves upward, pulling the sealing plug 31 and the movable tube 28 upward through the steel cable 32, blocking the main channel of the return water pipe 9, and at the same time opening the water return port 36, so that the water in the water storage tank 1 flows directly back to the ground through the heat exchange tube 8, the water supply tank 3, and the water return port 36 after passing through the heat exchange tube 8 and the water supply tank 3, realizing power-free emergency heat dissipation. Ensure that when the active circulation fails, gravity flow is used to maintain short-term heat dissipation and prevent the distribution box from being damaged due to overheating.
