The side of the temperature-conducting plate 42 away from the air inlet shell 41 is fixedly connected to the outer wall of the cabinet 1. The function of the drip nozzle 46 is to guide the water droplets to flow more smoothly into the drawer 47, ensuring that the water droplets can be collected in time, and further ensuring the safe operation of the electrical equipment inside the cabinet 1.
[0022] The connecting assembly 3 includes a connecting pipe 32, with a flexible hose 31 fixedly connected to the top of the connecting pipe 32.

[0023] Working principle:
[0024] The entire distribution cabinet mainly consists of cabinet 1, stepper motor 5, air guide assembly 2, connecting assembly 3, and air intake assembly 4. Cabinet 1 serves as the main body for housing various electrical equipment. Stepper motor 5 is installed on its top, acting as a power source to provide power support for the ventilation system. Air guide assembly 2 is connected to the output end of stepper motor 5 and is responsible for guiding and distributing the airflow direction. Connecting assembly 3 is used to achieve a quick connection between air intake branch pipe 6 and air intake assembly 4, ensuring the smooth construction of the ventilation channel. Air intake assembly 4 is installed on the outer walls on both sides of cabinet 1. Its main function is to introduce processed outside air into the interior of cabinet 1, providing an air source for heat dissipation of electrical equipment.
[0025] When the power distribution cabinet needs ventilation and heat dissipation, the stepper motor 5 is started first. The stepper motor 5 starts to rotate, and its output end is fixedly connected to the air guide assembly 2. As the stepper motor 5 rotates, the air guide assembly 2 also rotates synchronously. Air inlet branch pipes 6 are inserted into the outer walls on both sides of the air guide assembly 2. During the rotation of the air guide assembly 2, a certain air pressure difference will be formed around it, so that outside air is drawn into the air guide assembly 2.
[0026] The connecting component 3 plays a crucial connecting role in the entire ventilation system. It consists of components such as a flexible hose 31, a connecting pipe 32, a connecting branch pipe 33, a positioning ring 34, and a magnet 35. The outer wall of the air inlet branch pipe 6 is fixedly connected to the outer wall of the connecting pipe 32 at the top of the connecting component 3. The top of the connecting pipe 32 is connected to the flexible hose 31, which has a certain degree of flexibility. The inner wall of the connecting pipe 32 is fixedly connected to the connecting branch pipe 33, and the connecting branch pipe 33 is distributed in a linear array along the central axis of the connecting pipe 32. The side of the connecting branch pipe 33 away from the connecting pipe 32 is fixedly connected to the positioning ring 34 and the magnet 35, wherein the magnet 35 is distributed in a ring array along the central axis of the connecting branch pipe 33.
[0027] When it is necessary to connect the connecting component 3 to the air inlet component 4, the connecting branch pipe 33 is inserted into the fixed pipe 44 of the air inlet component 4. At this time, the outer wall of the positioning ring 34 will slide and connect with the inner wall of the fixed pipe 44, which plays a role in positioning and guiding, ensuring that the connecting branch pipe 33 can be accurately inserted into the fixed pipe 44. At the same time, the outer wall of the fixed pipe 44 and the inner wall of the connecting branch pipe 33 will also form a sliding connection, further stabilizing the connection.
[0028] The magnet 35 is designed to enhance the stability of the connection. When the connecting branch pipe 33 is inserted into the fixed pipe 44, the outer wall of the magnet 35 will come into contact with the inner wall of the iron ring 45 that is fixedly connected to the inner wall of the fixed pipe 44. Due to the magnetic force between the magnet 35 and the iron ring 45, the connection between the connecting branch pipe 33 and the fixed pipe 44 can be made tighter, preventing the connection from loosening due to airflow impact during ventilation, and ensuring that air can be smoothly transmitted from the connecting component 3 to the air intake component 4.
[0029] The air intake assembly 4 is a key component that introduces outside air into the cabinet 1 and processes it. It consists of components such as an air intake shell 41, a temperature-conducting plate 42, temperature-conducting fins 43, a fixing pipe 44, an iron ring 45, a drip nozzle 46, and a drawer 47. When outside air enters the air intake shell 41 of the air intake assembly 4 through the connecting assembly 3, it first comes into contact with the temperature-conducting plate 42, which is fixedly connected to the inner wall of the air intake shell 41. The temperature-conducting plate 42 is arranged in a linear array along the inner wall of the air intake shell 41, and its outer wall is also fixedly connected with temperature-conducting fins 43, which are arranged in a linear array along the outer wall of the temperature-conducting plate 42.
[0030] The main function of the temperature-conducting plate 42 and the temperature-conducting fins 43 is to regulate the temperature of the incoming air. In some cases, the temperature of the outside air may not match the required heat dissipation temperature inside the cabinet 1. For example, if the outside air temperature is too low, it may cause condensation on the electrical equipment inside the cabinet 1. Through the temperature-conducting plate 42 and the temperature-conducting fins 43, the heat emitted by the cabinet 1 itself and the heat emitted by the electrical components inside the cabinet 1 during operation can be conducted to the cabinet 1. Because the side of the temperature-conducting plate 42 away from the air inlet shell 41 is fixedly connected to the outer wall of the cabinet 1, the incoming air is appropriately heated or cooled to make its temperature more suitable for the heat dissipation of the electrical equipment, avoiding adverse effects on the electrical equipment due to excessive temperature differences.
[0031] Meanwhile, a fixed pipe 44 is fixedly connected to the inner wall of the air inlet shell 41, and the fixed pipe 44 is distributed in a linear array along the outer wall of the air inlet shell 41. An iron ring 45 is fixedly connected to the outer wall of the fixed pipe 44. The iron ring 45 not only plays a cooperating role in the connection process between the connecting component 3 and the air inlet component 4, but also enhances the structural strength of the air inlet shell 41.
[0032] A drawer box 47 is slidably connected to the inner wall at the bottom of the air inlet housing 41. The function of the drawer box 47 is to collect impurities such as water droplets that may be generated during the air handling process. For example, when the outside air humidity is high, after the temperature is regulated by the temperature guiding plate 42 and the temperature guiding fins 43, the water vapor in the air may condense into water droplets. These water droplets will slide down the inner wall of the air inlet housing 41 to the bottom and are eventually collected in the drawer box 47 to prevent water droplets from entering the cabinet 1 and damaging the electrical equipment.
[0033] In addition, a drip nozzle 46 is fixedly connected to the inner wall at the bottom of the air inlet shell 41, and the drip nozzle 46 is arranged in a linear array along the inner wall of the air inlet shell 41. The function of the drip nozzle 46 is to guide the water droplets to flow more smoothly into the drawer box 47, ensuring that the water droplets can be collected in time, and further ensuring the safe operation of the electrical equipment inside the cabinet 1.
[0034] During the ventilation and heat dissipation process of the power distribution cabinet, the components work closely together. First, the stepper motor 5 starts and drives the air guide component 2 to rotate, drawing outside air into the air guide component 2 through the air inlet branch pipe 6. Then, the drawn-in air is transmitted through the connecting component 3. The connecting component 3 ensures a stable connection with the air inlet component 4 through components such as the positioning ring 34 and the magnet 35, allowing the air to smoothly enter the air inlet component 4. The air entering the air inlet component 4 undergoes temperature regulation under the action of the temperature guiding plate 42 and the temperature guiding fins 43, making its temperature more suitable for heat dissipation of electrical equipment. At the same time, any water droplets or other impurities that may be generated are guided by the drip nozzle 46 to the drawer 47 for collection. Finally, the treated air is introduced into the cabinet 1 through the air inlet component 4, where it exchanges heat with the electrical equipment inside the cabinet 1, carrying away the heat generated by the electrical equipment. This achieves effective ventilation and heat dissipation of the power distribution cabinet, ensuring that the electrical equipment operates normally in a suitable temperature environment.
