Description
Technical Field
[0001] This utility model relates to the field of outdoor power distribution cabinet technology, specifically an outdoor power distribution cabinet with temperature regulation function. Background Technology
[0002] When in use, outdoor power distribution cabinets can be installed next to the green belt of the road, and their positioning settings can be configured. Depending on the usage requirements, they can supply power or provide electrical signals to nearby road devices, facilitating the location control and use of nearby devices.
[0003] For example, Chinese patent CN220710967U discloses an outdoor power distribution cabinet with temperature regulation function, featuring a cabinet body designed for easy positioning and assembly outdoors. It includes a semiconductor cooling plate nested and connected to the lower inner surface of the cabinet body, with an external fan connected to the outer surface of the semiconductor cooling plate via a heat sink. An air inlet is nested and assembled on the inner surface of the cabinet body and the upper side of the semiconductor cooling plate, with cooling fins connected to the outer side of the air inlet. This outdoor power distribution cabinet with temperature regulation function, equipped with a semiconductor cooling plate for easy cooling, works in conjunction with an external fan and external heat sink to cool the heating end of the semiconductor cooling plate. The cooling end, combined with the cooling fins and the built-in fan bracket, provides cooling during summer use of the cabinet body. Assembled at the bottom of the cabinet body, it effectively improves the internal cooling effect.
[0004] While the aforementioned patent effectively improves the cooling effect inside outdoor power distribution cabinets, the heating efficiency is generally low due to the heat generated by the self-heating of electrical appliances, which creates a heat cycle within the cabinet body and reduces its practicality.

It solves the problem that heating through the self-heating of electrical appliances to form a heat cycle inside the power distribution cabinet results in generally low heating efficiency and reduced practicality.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an outdoor power distribution cabinet with temperature regulation function, including a power distribution cabinet body, a cabinet door rotatably connected to the front of the power distribution cabinet body via a hinge, a heating mechanism on the upper surface of the power distribution cabinet body, and a cooling mechanism on the right side of the power distribution cabinet body.
[0007] The heating mechanism includes a protective frame installed on the upper surface of the power distribution cabinet body. A sealing plate is fixed to the upper surface of the protective frame with bolts. A fan and a heating box are installed on the bottom wall of the inner cavity of the protective frame. The heating box is located on the right side of the fan. The air outlet of the fan is connected to the left side of the heating box through a pipe. The right side of the heating box is connected to the protective frame and the power distribution cabinet body through pipes and extends into the interior of the power distribution cabinet body. A connecting pipe is installed at the air inlet of the fan. The bottom end of the connecting pipe is connected to the protective frame and the power distribution cabinet body and extends into the interior of the power distribution cabinet body.
[0008] The heating mechanism also includes a controller installed on the right side wall of the inner cavity of the protective frame. A temperature sensor is installed on the top wall of the inner cavity of the power distribution cabinet. The temperature sensor is electrically connected to the controller via a wire. The fan and the heating box are both electrically connected to the controller via wires.
[0009] Furthermore, a fixing cylinder is provided on both the left and right sides of the top wall of the inner cavity of the power distribution cabinet body, and a second fan is provided inside the fixing cylinder. The front and back of the fixing cylinder are provided with no less than two air inlets.
[0010] Furthermore, the cooling mechanism includes a frame fixed to the right side of the distribution cabinet body by bolts. A semiconductor cooling plate is provided on the right side wall of the inner cavity of the distribution cabinet body. The hot end of the semiconductor cooling plate passes through the distribution cabinet body and the frame and extends into the interior of the frame. The hot end of the semiconductor cooling plate is provided with at least two L-shaped fins. A protective net is provided on the right side of the frame. A fixing opening is provided through the lower surface of the distribution cabinet body.
[0011] Furthermore, the cooling mechanism also includes a first fan disposed inside the fixed port, a third filter screen disposed inside the fixed port, the third filter screen being located below the first fan, and the semiconductor cooling plate being electrically connected to the controller via wires.
[0012] Furthermore, the temperature sensor is located on the longitudinal central axis of the power distribution cabinet body.
[0013] Furthermore, the heating box is equipped with at least two heating wires inside.
[0014] Furthermore, at least two of the air inlets are evenly distributed on the front and back of the fixed cylinder.
[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0016] 1. This outdoor power distribution cabinet with temperature regulation function can sense the internal temperature of the cabinet body through a temperature sensor in winter. When the internal temperature of the cabinet body is lower than the threshold set by the temperature sensor, the temperature sensor sends a signal to the controller. The controller then turns on the fan and heating box to heat the inside of the cabinet body. When the internal temperature of the cabinet body is higher than the threshold set by the temperature sensor, the temperature sensor sends a signal to the controller, which then turns off the fan and heating box. This allows for rapid heating and provides a stable constant temperature environment for the electrical equipment inside the cabinet body.
[0017] 2. This outdoor power distribution cabinet with temperature regulation function, in summer, uses a temperature sensor inside the cabinet to sense the internal temperature. When the internal temperature exceeds the threshold set by the temperature sensor, the sensor sends a signal to the controller. The controller then activates the first fan and the semiconductor cooling plate. The left cold end of the semiconductor cooling plate cools the cabinet, thus lowering the internal temperature. When the temperature sensor detects that the internal temperature is below the threshold, it sends a signal to the controller, which then shuts off the semiconductor cooling plate and the first fan. The semiconductor cooling plate has at least two L-shaped fins at its hot end, which dissipate heat through the first fan. This regulates the internal temperature of the power distribution cabinet, preventing overheating and providing a stable, constant-temperature environment for the electrical equipment within the cabinet.

The right side of the power distribution cabinet body 1 is provided with a cooling mechanism 4, which can regulate the temperature inside the power distribution cabinet body 1 to prevent the internal temperature of the power distribution cabinet body 1 from overheating and causing damage to the electrical equipment inside the power distribution cabinet body 1. The cooling mechanism 4 is fixed to the front of the power distribution cabinet body 1 by a fixing lock.
[0025] In this embodiment, a fixing cylinder 5 is provided on both the left and right sides of the top wall of the inner cavity of the power distribution cabinet body 1. A second fan 6 is provided inside the fixing cylinder 5. At least two air inlets 7 are provided on the front and back of the fixing cylinder 5. The at least two air inlets 7 are evenly distributed on the front and back of the fixing cylinder 5.
[0026] It should be noted that when heating and cooling, the second fans 6 on the left and right sides can be started by the controller 306, which can improve the air circulation inside the power distribution cabinet body 1 and achieve uniform heating and cooling. Electrical equipment is installed on the back wall of the inner cavity of the power distribution cabinet body 1.
[0027] Please see Figure 2 In order to improve heating efficiency and provide a stable constant temperature environment for the electrical equipment inside the distribution cabinet body 1, the heating mechanism 3 in this embodiment includes a protective frame 301 set on the upper surface of the distribution cabinet body 1. A sealing plate 302 is fixed to the upper surface of the protective frame 301 by bolts. A fan 303 and a heating box 304 are set on the bottom wall of the inner cavity of the protective frame 301. The heating box 304 is located on the right side of the fan 303. The air outlet of the fan 303 is connected to the left side of the heating box 304 through a pipe. The right side of the heating box 304 is connected to the protective frame 301 and the distribution cabinet body 1 through a pipe and extends into the interior of the distribution cabinet body 1. A connecting pipe 305 is set at the air inlet of the fan 303. The bottom end of the connecting pipe 305 is connected to the protective frame 301 and the distribution cabinet body 1 and extends into the interior of the distribution cabinet body 1.
[0028] In this embodiment, the heating mechanism 3 also includes a controller 306 disposed on the right side wall of the inner cavity of the protective frame 301. A temperature sensor 307 is disposed on the top wall of the inner cavity of the power distribution cabinet body 1. The temperature sensor 307 is electrically connected to the controller 306 via a wire. The fan 303 and the heating box 304 are both electrically connected to the controller 306 via wires. The temperature sensor 307 is located on the longitudinal central axis of the power distribution cabinet body 1. The heating box 304 is provided with at least two heating wires inside. In winter, the temperature sensor 307 can sense the temperature value inside the power distribution cabinet body 1. When the temperature value inside the power distribution cabinet body 1 is lower than the threshold set by the temperature sensor 307, the temperature sensor 307 sends a signal to the controller 306. The controller 306 turns on the fan 303 and the heating box 304 to heat the inside of the power distribution cabinet body 1.
[0029] It should be noted that when the temperature inside the power distribution cabinet body 1 is higher than the threshold set by the temperature sensor 307 during the heating process, the temperature sensor 307 sends a signal to the controller 306. The controller 306 then shuts down the fan 303 and the heating box 304. During the heating process, a stable constant temperature environment can be provided for the electrical equipment inside the power distribution cabinet body 1. The threshold set by the temperature sensor 307 can be 5℃ to 35℃.
[0030] Please see Figures 3 to 4 In order to regulate the temperature inside the power distribution cabinet body 1 and prevent overheating that could damage the electrical equipment inside, the cooling mechanism 4 in this embodiment includes a frame 401 fixed to the right side of the power distribution cabinet body 1 by bolts. A semiconductor cooling plate 402 is provided on the right side wall of the inner cavity of the power distribution cabinet body 1. The hot end of the semiconductor cooling plate 402 passes through the power distribution cabinet body 1 and the frame 401 and extends into the interior of the frame 401. The hot end of the semiconductor cooling plate 402 is provided with at least two L-shaped loose pieces 403. A protective net 404 is provided on the right side of the frame 401. A fixing port 405 is provided through the lower surface of the power distribution cabinet body 1.
[0031] In this embodiment, the cooling mechanism 4 also includes a first fan 406 disposed inside the fixing port 405. In summer, the temperature sensor 307 inside the power distribution cabinet body 1 senses the temperature inside the power distribution cabinet body 1. When the temperature inside the power distribution cabinet body 1 is higher than the threshold set by the temperature sensor 307, the temperature sensor 307 sends a signal to the controller 306. The controller 306 turns on the first fan 406 and the semiconductor cooling plate 402. The left cold end of the semiconductor cooling plate 402 performs cooling, which can cool the temperature inside the power distribution cabinet body 1. A third filter 407 is disposed inside the fixing port 405. The third filter 407 is located below the first fan 406. The semiconductor cooling plate 402 is electrically connected to the controller 306 through a wire.
[0032] It should be noted that when the temperature sensor 307 detects that the internal temperature of the power distribution cabinet body 1 is lower than the threshold set by the temperature sensor 307, the temperature sensor 307 sends a signal to the controller 306. The controller 306 turns off the semiconductor cooling plate 402 and the first fan 406. The semiconductor cooling plate 402 has at least two L-shaped fins 403 at its hot end, which can dissipate heat through the first fan 406. This can regulate the temperature inside the power distribution cabinet body 1, prevent the internal temperature of the power distribution cabinet body 1 from overheating, and provide a stable constant temperature environment for the electrical equipment in the power distribution cabinet body 1.
[0033] The working principle of the above embodiments is as follows:
[0034] (1) In winter, the temperature value inside the power distribution cabinet body 1 can be sensed by the temperature sensor 307. When the temperature value inside the power distribution cabinet body 1 is lower than the threshold set by the temperature sensor 307, the temperature sensor 307 sends a signal to the controller 306. The controller 306 turns on the fan 303 and the heating box 304 to heat up the inside of the power distribution cabinet body 1. When the temperature value inside the power distribution cabinet body 1 is higher than the threshold set by the temperature sensor 307, the temperature sensor 307 sends a signal to the controller 306. The controller 306 turns off the fan 303 and the heating box 304. When heating up, a stable constant temperature environment can be provided for the electrical equipment inside the power distribution cabinet body 1.
[0035] (2) In summer, the temperature sensor 307 inside the power distribution cabinet 1 senses the temperature inside the power distribution cabinet 1. When the temperature inside the power distribution cabinet 1 is higher than the threshold set by the temperature sensor 307, the temperature sensor 307 sends a signal to the controller 306. The controller 306 turns on the first fan 406 and the semiconductor cooling plate 402. The left cold end of the semiconductor cooling plate 402 is cooled, and the temperature inside the power distribution cabinet 1 is cooled. When the temperature sensor 307 senses that the temperature inside the power distribution cabinet 1 is lower than the threshold set by the temperature sensor 307, the temperature sensor 307 sends a signal to the controller 306. The controller 306 turns off the semiconductor cooling plate 402 and the first fan 406. The number of L-shaped fins 403 at the hot end of the semiconductor cooling plate 402 is not less than two. They can dissipate heat through the first fan 406, which can regulate the temperature inside the power distribution cabinet 1 and prevent the temperature inside the power distribution cabinet 1 from overheating. This provides a stable constant temperature environment for the electrical equipment in the power distribution cabinet 1.
