[0013] In use, the user increases the area of ​​the filter plate to ensure that the airflow speed after passing through the filter plate meets the user's requirements. The air guide plate directs the airflow to multiple fans. When the fans start, they create a negative pressure zone at the top of the fans, allowing air to rush into the filter frame. The fans then send the air into the air duct, which in turn sends the filtered air into multiple installation cavities to maintain the temperature of the electronic components installed inside the cabinet. In addition, the filter plate has a dehumidification layer, which reduces the humidity of the airflow, thus ensuring the working environment of the electronic components. Attached Figure Description

[0019] Example 1

[0020] like Figures 1-4 As shown in the figure, the centrally located switch cabinet proposed in this embodiment includes a cabinet body 1, an air duct 8, and a filter assembly. The cabinet body 1 is provided with a foot pedal assembly 14 and multiple partition plates 13. The cabinet body 1 also has multiple mounting cavities 101. The foot pedal assembly 14 and multiple partition plates 13 are distributed one-to-one between the multiple mounting cavities 101. The air duct 8 is provided on the cabinet body 1 and is connected to each of the multiple mounting cavities 101. The filter assembly includes a filter frame 3 provided on the cabinet body 1, a filter plate 4 detachably provided on the filter frame 3, and an air guide plate 5 inclined on the filter frame 3. Multiple fans 6 are provided on the filter frame 3. Multiple closed doors 2 are hinged on the cabinet body 1 and are distributed one-to-one at the multiple mounting cavities 101. The filter frame 3 is connected to the air duct 8. After the filter plate 4 is slidably placed on the filter frame 3, the user screws bolts into the filter plate 4 and the filter 3 from below to fix the filter plate 4, thereby reducing the difficulty of replacing the filter plate.

[0021] In this embodiment, the user increases the area of ​​the filter plate 4 to ensure that the airflow speed after passing through the filter plate 4 meets the user's requirements. The air guide plate 5 guides the air to multiple fans 6. When the fans 6 are started, they create a negative pressure zone at the top of the fans 6, allowing air to rush into the filter frame 3. The fans 6 send the air into the air duct 8, and the air duct 8 sends the filtered air into multiple mounting cavities 101 to maintain the temperature of the electronic components installed inside the cabinet 1. In addition, the filter plate 4 has a dehumidification layer, which reduces the humidity of the air flowing through it, thereby ensuring the working environment of the electronic components.

[0022] Example 2

[0023] like Figure 1 , Figure 2 and Figure 4As shown in this embodiment, a centrally located switchgear is proposed. Compared to Embodiment 1, in this embodiment, the cabinet 1 is equipped with multiple sets of exhaust assemblies, each corresponding to and connected to multiple mounting cavities 101. Each exhaust assembly includes an exhaust frame 10 mounted on the cabinet 1, a baffle plate 11 rotatably mounted on the exhaust frame 10, a return spring mounted on the baffle plate 11, and an electromagnetic block 12 mounted on the exhaust frame 10; the baffle plate 11 is made of magnetic metal. The air duct 8 is connected to multiple continuously curved air outlet pipes 9, each with a uniformly distributed air outlet hole, and the multiple air outlet pipes 9 are distributed within the multiple mounting cavities 101.

[0024] In this embodiment, after air is blown into multiple mounting cavities 101, the air force drives multiple baffles 11 to rotate. At the same time, the power supply and the electromagnetic block 12 are energized, allowing the electromagnetic block 12 to attract the baffles 11. When the environment inside the mounting cavity 101 meets the user's needs, the fan 6 is turned off, and the electromagnetic block 12 is disconnected from the power supply. The reset spring drives the baffles 11 to reset, thereby preventing unfiltered air from directly contacting the electrical components and ensuring the service life of the electrical components.

[0025] Example 3

[0026] like Figures 1-3 As shown, this embodiment proposes a centrally located switch cabinet. Compared to Embodiment 1, in this embodiment, the foot pedal assembly 14 includes a mounting bracket 141 mounted on the cabinet 1, a foot pedal 142 slidably mounted on the mounting bracket 141 and the cabinet 1, a movable frame 143 slidably mounted on the foot pedal 142, movable wheels 144 mounted at both ends of the movable frame 143, and a support plate 145 damped and rotatably mounted on the movable frame 143; the movable wheels 144 are in rolling contact with the movable frame 143. Multiple temperature sensors are also mounted on the cabinet 1, and a display assembly 15 is mounted on the filter frame 3. All the multiple temperature sensors are electrically connected to the display assembly 15.

[0027] In this embodiment, the user pulls the mounting bracket 141 out of the cabinet 1 until the support plate 145 is fully extended out of the cabinet 1. Then, according to the direction of pulling out, the user moves the movable bracket 143 to the position furthest from the cabinet, rotates the support plate 145 to contact the ground, and then the user steps on the foot pedal 142 to replace the filter plate 4, thereby reducing the maintenance difficulty of the filter assembly.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
