Description
Technical Field
[0001] This utility model relates to the field of power distribution cabinet technology, specifically a low-voltage power distribution cabinet with temperature control capability. Background Technology
[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.
[0003] Currently, different numbers of electronic components are installed in different locations within existing power distribution cabinets. When the cabinet is in operation, these components generate varying amounts of heat, which accumulates within the cabinet. Existing power distribution cabinets primarily rely on cooling fans, which are fixed at a specific height. While these fans provide some cooling, they cannot adjust the temperature of different areas based on the actual temperature within the cabinet. This results in some areas of the electronic components experiencing continuous temperature increases, affecting their lifespan. Therefore, we propose a low-voltage power distribution cabinet with temperature control capabilities. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Please see Figures 1 to 5 This utility model provides a technical solution: a low-voltage distribution cabinet with temperature control, comprising a low-voltage distribution cabinet body 1, a cabinet door on one side of the low-voltage distribution cabinet body 1, an air inlet box 2 inside one side of the low-voltage distribution cabinet body 1, several air intakes 3 inside the other side of the low-voltage distribution cabinet body 1, a connecting box 4 fixedly installed on the outside of the low-voltage distribution cabinet body 1, the air intakes 3 communicating with the interior of the connecting box 4, an exhaust fan 5 inside one side of the connecting box 4, temperature sensors 6 on the inner wall of the low-voltage distribution cabinet body 1 and on one side of the several air intakes 3, several equipment mounting plates 7 inside the low-voltage distribution cabinet body 1, and a temperature controller 20 at the bottom inside the low-voltage distribution cabinet body 1. The temperature controller 20 is prior art. Electrically connected to temperature sensor 6, exhaust fan 5, and liquid pump, the equipment mounting plate 7 has a serpentine tube 8 inside. A water tank 9 is installed at the bottom of the low-voltage distribution cabinet body 1. A water distributor 10 is installed at the bottom of one side of the water tank 9. A liquid pump is installed inside the water tank 9. The output end of the liquid pump is fixedly connected to the input end of the water distributor 10. A connecting pipe 11 is fixedly installed at the output end of the water distributor 10. One end of the connecting pipe 11 is fixedly connected to one end of the serpentine tube 8. The connecting pipe 11 is a flexible hose that can deform when the equipment mounting plate 7 moves up and down. A pre-reserved length of the connecting pipe 11 is provided during installation. The serpentine tube 8 is a copper pipe to facilitate heat exchange. A collecting pipe 12 is installed on one side of the water tank 9. The other end of the serpentine tube 8 is fixedly connected to the input end of the collecting pipe 12.
[0018] The equipment mounting plate 7 includes two mounting plate bodies 71 and two side connecting plates 72. The two side connecting plates 72 are fixedly installed on the corresponding sides of the two mounting plate bodies 71. The mounting plate bodies 71 have grooves inside that mate with the serpentine tube 8. The mounting plate bodies 71 also have screw mounting holes for installing electrical components. These screw mounting holes are offset from the grooves that mate with the serpentine tube 8, exposing part of the serpentine tube 8 to facilitate direct heat exchange with the air inside the distribution cabinet. When electrical components are installed on the mounting plate bodies 71, they are closer to the serpentine tube 8, making heat exchange even easier. Side mounting strips 21 are fixedly installed on the corresponding sides inside the low-voltage distribution cabinet body 1. The two side mounting strips 21 each have side adjustment grooves 22 inside. The side connecting plates 72 are inserted into the side adjustment grooves 22 and slidably connected to them. Screw holes are provided inside the side connecting plates 72 and the side mounting strips 21 to facilitate adjustment of the position of the mounting plate bodies 71.
[0019] The air intake box 2 has several snap-fit plates 13 inside. A moisture-proof particle board 14 is snapped into the inside of the manifold 12 above the snap-fit plates 13. A door 15 is hinged to one side of the air intake box 2. A dustproof net 16 is installed inside the door 15. The air intake box 2 and the door 15 are provided with a locking structure that cooperates with each other, so as to facilitate opening the door 15 to disassemble and replace the moisture-proof particle board 14. The moisture-proof particle board 14 contains moisture-proof desiccant particles. The air intake box 2 is connected to the interior of the low-voltage distribution cabinet body 1. It should be noted that this distribution cabinet is suitable for indoor use, but not for harsh environments such as outdoor use. The back of the low-voltage distribution cabinet body 1 is provided with a cable routing hole.
[0020] Both sides of the water tank 9 are equipped with heat dissipation fins 17. A liquid filling port is provided on one side of the water tank 9 for adding coolant. A sealing cap is provided on the top of the liquid filling port. The heat dissipation fins 17 extend into the interior of the water tank 9 to exchange heat with the coolant. Both sides of the low-voltage distribution cabinet body 1 are fixedly installed with support legs 18. The support legs 18 adopt a hollow design. A base plate 19 is fixedly installed at the bottom of the support legs 18. The heat dissipation fins 17 can dissipate heat from the coolant in the water tank 9 by contacting the outside air. Of course, if it is necessary to increase the heat dissipation efficiency, a fan can also be installed on one side of the support legs 18 for heat dissipation, depending on the actual situation.
[0021] In summary, this temperature-controlled low-voltage distribution cabinet, when in use, allows air to be expelled from the main body 1 of the cabinet through several air intakes 3 by turning on the exhaust fan 5. During the airflow, the temperature sensor 6 monitors the air temperature in each area. When the temperature in a certain area is too high and needs to be controlled, the liquid pump in the water tank 9 can be turned on by the temperature controller 20 to input coolant into the water distributor 10 connected to that area, and then into the serpentine tube 8 through the connecting pipe 11. The coolant circulates in the serpentine tube 8 to remove heat from the electronic components in that area, thus achieving temperature control. The coolant in the serpentine tube 8 flows back into the water tank 9 through the collecting pipe 12 and is then cooled by the heat dissipation fins 17. When the exhaust fan 5 is turned on to expel air from the main body 1 of the low-voltage distribution cabinet, outside air enters the main body 1 of the low-voltage distribution cabinet through the air intake box 2. When the air enters the air intake box 2, the moisture-proof particle board 14 and the dustproof net 16 filter the dust and moisture in the air, thus achieving the function of dust and moisture prevention.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
