Description

Technical Field

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

[0002] In power systems, distribution boxes are core equipment for power distribution. Their heat dissipation performance directly impacts operational stability and service life. Traditional distribution box cooling solutions rely on fans for forced convection when using air cooling. This can lead to dust clogging the filters, reducing heat dissipation efficiency. Long-term fan operation also carries the risk of mechanical failure (such as bearing wear and motor burnout), resulting in high maintenance costs. The fans are also unable to cope with high-power density scenarios and can easily cause local hot spots, leading to component aging and even fires.

[0003] Liquid cooling solutions often use fixed-flow pumping, which cannot be dynamically adjusted based on real-time temperature. This can lead to "overcooling" or "undercooling", resulting in significant energy waste. Furthermore, the system has low integration and requires additional configuration of temperature control valves, sensors, and electronic control units. This results in a complex and costly structure. Electronic components are particularly susceptible to electromagnetic interference and moisture damage, especially in outdoor or harsh environments.

[0015] The intelligent temperature-controlled heat dissipation distribution box described in the present invention utilizes the natural cold source of groundwater to continuously remove heat from the distribution box through water circulation, thereby avoiding local overheating, effectively reducing water resource waste, and effectively ensuring the heat dissipation effect of the combined distribution box.

[0016] The intelligent temperature-controlled heat dissipation distribution box described in the present invention controls the opening of the regulating valve by driving the transmission rack to move due to the thermal expansion of the thermal expansion fluid in the heat-conducting seat, thereby automatically controlling the heat dissipation effect of the corresponding cabinet;

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] As an embodiment of the present invention, Figures 1 to 8 As shown, the intelligent temperature-controlled heat dissipation distribution box described in 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 a circumferentially distributed cabinet 4, and the bottom of the cabinet 4 is connected to a hollow bottom plate 5. The hollow bottom plate 5 is connected to 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 pipes 8 are provided at the corners of the cabinet 4. The lower end of the heat exchange pipe 8 is connected to the hollow bottom plate 5, and the upper end of the heat exchange pipe 8 is connected to the water storage tank 1. The water storage tank 1 is connected to the underground through a return pipe 9.

[0031] During use, the water supply tank 3 draws groundwater through the water pump 7, and after the flow is controlled by the regulating valve 6, it flows into the heat exchange pipe 8 in the cabinet 4 through the hollow bottom plate 5. After absorbing the heat from the distribution box, the heated water flows into the water storage tank 1 through the heat exchange pipe 8, and finally flows back to the ground through the return pipe 9, reducing water resource waste and effectively coping with high temperature environments.

[0032] It should be pointed out 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 groundwater need to be treated with rust-proof treatment (such as coating with epoxy resin); the hollow bottom plate 5 must have sufficient pressure-bearing capacity (aluminum alloy with a thickness of ≥5mm is recommended) to prevent deformation caused by long-term water impact.

[0033] To facilitate control of the regulating valve 6, as an embodiment of the present invention, a vertically arranged back panel 10 is installed on the inner side of the cabinet body 4, and a heat conducting seat 11 is installed on the back side of the cabinet body 4. The heat conducting seat 11 passes through the cabinet body 4 and is connected to the back panel 10. A piston chamber 12 with a downward opening and filled with a thermal expansion fluid is provided in the heat conducting seat 11. A piston 13 is slidably connected in the piston chamber 12. The lower part of the piston 13 is connected to the piston rod 14 and the transmission rack 15 in sequence. The valve stem of the regulating valve 6 is connected to the regulating gear 16 meshing with the transmission rack 15. It should be added that the side of each set of cabinet bodies 4 is hinged with a cabinet door 38 by a hinge, and the cabinet door 38 is in a closed state when in use.

[0034] During use, when the temperature of the cabinet 4 rises, the fluid expands and pushes the piston 13 downward, driving the transmission rack 15 through the piston rod 14. The transmission rack 15 engages with the regulating 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, and increasing the heat dissipation effect inside the corresponding cabinet 4.

[0035] The thermal expansion fluid may be paraffin.

[0036] In order to improve the heat dissipation effect in the cabinet 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 the rotating shaft 18, the upper end of the rotating shaft 18 is connected to the blade 19, and the lower part of the rotating shaft 18 is a hollow structure connected to the rotary joint 40. The rotary joint 40 is connected to the regulating valve 6 through a pipe passing through the hollow bottom plate 5. The lower side of the rotating shaft 18 is connected to the circumferentially distributed nozzles 20, and a through hole 34 connected to the inner side of the protective shell 17 is opened on the hollow bottom plate 5.

[0037] During use, water flows through the rotary joint 40 into the hollow structure of the rotating shaft 18, and is ejected at high speed from the side nozzle 20, pushing the paddle 19 to rotate. The paddle 19 pushes the air at the bottom of the cabinet 4 to move upward quickly, thereby promoting the rapid flow of air in the cabinet 4, thereby better contacting the heat exchange tube 8, thereby improving the heat dissipation effect inside the cabinet 4; at the same time, it can also address the problem that the heat dissipation efficiency is difficult to meet the rapid heating of local components.

[0038] It should be pointed out that in order to increase the service life of the equipment, the groundwater needs to be filtered (filter accuracy ≤ 100 mesh) 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.

[0039] In order to facilitate the water in the heat exchange tube 8 to enter the water storage tank 1, as an embodiment of the present invention, the outer side of the heat exchange tube 8 is connected to the heat exchange fin 21, 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, and a movable frame 22 is provided on the top of the water storage tank 1. A positioning tube 23 is fixedly connected to the movable frame 22, and 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 outer side of the heat exchange tube 8, and the upper part of the positioning tube 23 is provided with a water inlet 39 connected to the water storage tank 1.

[0040] When in use, in the initial state, the positioning tube 23 is sleeved on the heat exchange tube 8. The water discharged upward from the heat exchange tube 8 enters the positioning tube 23 and is discharged through the water inlet 39 of the positioning tube 23 and falls into the water storage tank 1, thereby preventing the water in the water storage tank 1 from reversely entering the heat exchange tube 8 through the water inlet 39.

[0041] When the water pump 7 is not working, the movable frame 22 can be lifted upward, thereby pulling all the positioning tubes 23 upward. After the lower end of the positioning tube 23 is separated from the heat exchange tube 8, the water in the water storage tank 1 will flow downward through the heat exchange tube 8, thereby ensuring the heat dissipation effect of the combined distribution box 2 in a short time and realizing emergency cooling work.

[0042] In order to facilitate the automatic upward driving of the movable frame 22 , as an embodiment of the present invention, a thermal expansion bag 24 is connected between the middle portion of the movable frame 22 and the water storage tank 1 .

[0043] During use, if the water pump 7 fails, the water guiding and cooling effect cannot be guaranteed, the temperature inside the combined water storage tank 1 is too high, and the thermal expansion bag 24 expands enough to push the movable frame 22 upward, thereby automatically pulling the positioning tube 23 upward, so that the water in the water storage tank 1 moves downward through the heat exchange tube 8, thereby realizing heat dissipation inside the cabinet 4.

[0044] It should be noted that the thermal expansion bag 24 of the present invention can be replaced with other thermal expansion structures or with electronic control equipment to achieve automatic control of the movable frame 22, such as automatic lifting of the movable frame through an electric telescopic rod combined with a temperature detection system.

[0045] In order to facilitate the pre-control of 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 on the inner side of the cabinet body 4, and 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 the gas spring rod 26. The back side of the cabinet body 4 is provided with a groove 35 corresponding to the thermal conductive seat 11, and the thermal conductive seat 11 is connected to the inner wall of the groove 35 through a sealing gasket 27.

[0046] 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 thermal seat 11 to move downward, thereby driving the transmission rack 15 to move downward and driving the adjusting gear 16 to rotate, further increasing the opening of the regulating valve 6; in this way, the opening of the regulating valve 6 can be automatically controlled according to the number of electrical equipment installed on the back panel 10; the thermal seat 11 is sealed with the groove 35 of the cabinet body 4 through the sealing gasket 27 to prevent dust and water vapor from entering the cabinet body 4, while ensuring that heat is effectively conducted to the piston chamber 12.

[0047] In order to facilitate the control of the flow direction of water in the water storage tank 1 and meet the needs of emergency use, as an embodiment of the present invention, the return water pipe 9 vertically passes through the water supply tank 3, and the side of the return water pipe 9 is provided with a return water port 36 connected to the water supply tank 3. The return water pipe 9 is sealed and slidably connected to the movable pipe 28, and the inner wall of the return water pipe 9 is connected to the supporting ring 29. When the movable pipe 28 is squeezed on the supporting ring 29, the return water port 36 is closed. The upper inner part of the movable pipe 28 is connected to the sealing ring 30, and a sealing plug 31 is provided on the lower inner side of the sealing ring 30. The upper end of the sealing plug 31 is connected to the movable frame 22 by 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 water pipe 9 is provided above the sealing ring 30. It should be pointed out that the contact surface between the lower end face of the movable pipe 28 and the supporting ring 29 needs to be ground and polished to improve the sealing performance.

[0048] During use, when the movable frame 22 moves upward, the steel cable 32 is pulled upward, thereby driving the sealing plug 31 upward to squeeze the sealing ring 30, and driving the movable tube 28 upward to squeeze the limiting ring 37. At this time, the sealing plug 31 cooperates with the sealing ring 30 and the limiting ring 37 to block the return pipe 9; after the movable ring moves upward, the return port 36 is opened, and the water in the water supply tank 3 can enter the lower part of the return pipe 9 through the return port 36;

[0049] When the movable frame 22 moves upward, it pulls all the positioning tubes 23 upward. After the lower end of the positioning tube 23 is separated from the heat exchange tube 8, the water in the water storage tank 1 will flow downward through the heat exchange tube 8 into the hollow bottom plate 5, and then enter the protective shell 17, enter the water supply tank 3 through the nozzle 20, the rotary joint 40, and the regulating valve 6, and then flow back to the underground through the return pipe 9, thereby ensuring the heat dissipation effect of the combined distribution box 2 in a short time and realizing emergency cooling work.

[0050] In order to facilitate the cooling of the water in the water tank 1 , as an embodiment of the present invention, a heat dissipation fin 33 is connected to the side of the water tank 1 .

[0051] During use, the heat dissipation treatment of the water in the water tank 1 can be achieved through the heat dissipation fins 33, so that when the water in the water tank 1 reversely enters the heat exchange tube 8, it can still have a certain heat dissipation effect on the heat exchange tube 8.

[0052] The working principle of the present invention is as follows:

[0053] During normal operation, the water supply tank 3 draws groundwater through the water pump 7, and after the flow is controlled by the regulating valve 6, it flows into the hollow bottom plate 5 at the bottom of the cabinet 4; the cold water enters the heat exchange tube 8 at the corner of the cabinet 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 along the heat exchange tube 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 pipe 9, forming a closed loop circulation;

[0054] Among them, when the temperature inside the cabinet 4 rises, the thermal expansion fluid in the heat-conducting seat 11 expands, pushing the piston 13 downward, and driving the transmission rack 15 through the piston 13 rod, engaging the adjusting gear 16 to increase the opening of the regulating valve 6, increase the water supply flow, and enhance heat dissipation; and, when the number of electrical equipment installed on the back panel 10 increases, the weight of the back panel 10 increases, and the gas spring rod 26 pushes the heat-conducting seat 11 downward, and adjusts the opening of the regulating valve 6 in advance to adapt to higher heat dissipation requirements; in the protective shell 17 on the upper part of the hollow bottom plate 5, water flows through the rotary joint 40 into the hollow structure of the rotating shaft 18, and is ejected at high speed from the nozzle 20, pushing the blade 19 to rotate, accelerating the upward flow of air at the bottom of the cabinet 4, promoting heat exchange between the air and the heat exchange tube 8, and coping with the problem of rapid heating of local components.

[0055] The positioning tube 23 is sleeved on the upper end of the heat exchange tube 8 , and the heated water flows into the water storage tank 1 through the water inlet 39 of the positioning tube 23 , preventing the water in the water storage tank 1 from flowing back into the heat exchange tube 8 .

[0056] In the emergency state of a water pump 7 failure, the temperature in the water tank 1 rises, causing the thermal expansion bag 24 to expand, pushing the movable frame 22 upward, and the positioning tube 23 to separate from the heat exchange tube 8. Under the action of gravity, the water in the water tank 1 flows back along the heat exchange tube 8 into the cabinet 4, and quickly dissipates heat through the hollow bottom plate 5, nozzle 20 and other structures;

[0057] At the same time, the movable frame 22 moves upward, pulling the sealing plug 31 and movable pipe 28 upward via the steel cable 32, blocking the main channel of the return pipe 9. At the same time, the return port 36 is opened, allowing the water in the water storage tank 1 to flow directly back into the ground through the return port 36 after passing through the heat exchange pipe 8 and the water supply tank 3, thus achieving unpowered emergency heat dissipation. This ensures that if the active circulation fails, gravity flow can maintain short-term heat dissipation to prevent overheating and damage to the distribution box.

[0058] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention.
