[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides a low-voltage reactive power compensation cabinet with convenient heat dissipation, such as Figures 1-4 As shown, it includes a cabinet body 1, a cabinet door 2 is installed on the front of the cabinet body 1, air inlet components 3 are installed on the bottom of both sides of the cabinet body 1, and an air outlet component 4 is installed on the top of the cabinet body 1. The air inlet component 3 includes an air inlet channel 31, and air inlet channels 31 connected to the interior of the cabinet body 1 are installed on the bottom of both sides of the cabinet body 1. Several louvers 311 are installed at the outer openings of the air inlet channels 31, and a dustproof net 32 ​​is installed on the inner side of the air inlet channel 31. An air inlet fan 33 is installed on the side of the dustproof net 32 ​​away from the louver 311. The bottom of the air inlet channel 31 is connected to a dust exhaust pipe 34, and a sealing cover 341 is installed at the outer end of the dust exhaust pipe 34.

[0024] The present invention realizes efficient heat dissipation and effective dust prevention inside the cabinet through a carefully designed air inlet assembly. Several louvers installed at the outer opening of the air inlet channel not only allow air circulation, but also effectively prevent external dust from directly entering the cabinet. The dust screen installed on the inner side of the air inlet channel further blocks the dust in the air, ensuring that the air entering the cabinet is relatively clean. The air inlet fan installed on the side of the dust screen away from the louver 311 provides a continuous and stable airflow to the inside of the cabinet, ensuring the heat dissipation effect. In addition, the dust exhaust pipe connected to the bottom of the air inlet channel and the sealing cover installed at its outer end facilitate regular cleaning of accumulated dust, keeping the air inlet channel unobstructed and the interior of the cabinet clean. In summary, the low-voltage reactive compensation cabinet with convenient heat dissipation of the present invention performs well in both heat dissipation and dust prevention, effectively improving the stability and service life of the equipment.

[0025] In this embodiment, the plurality of louvers 311 are all arranged at an angle, and the plurality of louvers 311 are arranged at equal intervals. The height of the outer ends of the louvers 311 is lower than the height of the inner ends thereof, so as to block external dust.

[0026] Specifically, the inner wall of the outer end of the dust exhaust pipe 34 is provided with an internal thread, and the sealing cover 341 is provided with an external thread. The sealing cover 341 is threadedly connected to the dust exhaust pipe 34 to facilitate the sealing and opening of the dust exhaust pipe 34.

[0027] Furthermore, a dust inlet 342 is provided at the top of the dust exhaust pipe 34 , and the dust inlet 342 is connected to the bottom end of the air inlet channel 31 , so that the dust blocked by the dustproof net can fall into the dust exhaust pipe 34 through the dust inlet 342 .

[0028] Furthermore, the air outlet assembly 4 includes a convex cover 41, both sides of which are provided with air outlets 411, and an air outlet fan 412 is installed below the inner portion of the convex cover 41. By turning on the air outlet fan 412, the hot air inside the cabinet 1 is drawn to the outside.

[0029] Furthermore, the air outlet 411 is arranged obliquely, and the outer side height is lower than the inner side height to prevent external dust or water stains from entering.

[0030] Furthermore, a number of mounting plates 5 are sequentially installed inside the cabinet 1 from top to bottom, and a vent 51 is provided in the middle of the mounting plate 5 to facilitate the passage of air from bottom to top.

[0031] Furthermore, the bottom of both sides of the convex cover 41 are equipped with plug rods 413, and the top of the cabinet 1 is provided with sockets on both sides, and the plug rods 413 are plugged into the sockets. By inserting the plug rods 413 into the sockets, the convex cover 41 is easily positioned and removed, so as to facilitate the subsequent maintenance and replacement of the air outlet assembly 4.

[0032] When the low-voltage reactive power compensation cabinet with convenient heat dissipation of the present invention is in use, the air inlet component 3 and the air outlet component 4 work together to achieve efficient heat dissipation inside the cabinet 1. Several inclined and evenly spaced louvers 311 are installed at the outer opening of the air inlet channel 31, allowing external air to circulate in while effectively blocking dust from directly entering the cabinet. The dust net 32 ​​further filters dust in the air to ensure that the air entering the cabinet is relatively clean. The continuous operation of the air inlet fan 33 and the air outlet fan 412 provides a stable airflow inside the cabinet, taking away the heat generated by the electrical components and achieving a heat dissipation effect.

[0033] As time goes by, when the dust blocked by the dustproof net 32 ​​falls into the dust exhaust pipe 34 and accumulates to a certain amount, the sealing cover 341 can be rotated to open and the dust accumulated in the dust exhaust pipe 34 can be discharged to keep the air inlet channel unobstructed and the interior of the cabinet clean.

[0034] Several mounting plates 5 with vents 51 are installed sequentially from top to bottom within the cabinet 1. This not only facilitates the installation and wiring of electrical components but also promotes uniform heat distribution and removal. Airflow enters the cabinet from the air inlet assembly 3, passes through the vents 51 of the mounting plates 5, and then flows upwards, finally being discharged through the air outlet assembly 4.

[0035] The side of the raised cover 41 of the air outlet assembly 4 is provided with an oblique air outlet 411, which is lower than the inner side. This design effectively prevents dust and water from entering the cabinet. An air outlet fan 412 is installed underneath the raised cover 41 and continuously operates to draw hot air from the cabinet and discharge it out of the cabinet through the air outlet 411, completing the heat dissipation process.

[0036] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
