[0025] See also Figure 1-5The utility model provides an embodiment: a distribution box with enhanced heat dissipation and dust removal capabilities, including a distribution box body 10, in which four dust removal heat dissipation pipes 16 are embedded and installed on the left and right side walls of the inner cavity of the distribution box body 10 at equal intervals, and the lower end of each of the dust removal heat dissipation pipes 16 extends downward through the bottom of the distribution box body 10, the base 18 and the concentrated hollow plate 20, and enters the inner cavity of the concentrated hollow plate 20, so that the inner cavity of the dust removal heat dissipation pipe 16 is connected to the inner cavity of the concentrated hollow plate 20, and an air suction machine 19 is fixedly connected to the bottom end surface of the concentrated hollow plate 20, and the air suction output end of the air suction machine 19 is connected to the inner cavity of the concentrated hollow plate 20, The centralized hollow plate 20 is fixed to the concave end surface of the base 18, and each of the dust removal and heat dissipation tubes 16 is evenly spaced with dust suction ports 22, and the outer semicircular surface of the dust removal and heat dissipation tube 16 is provided with heat absorption holes 17 between the two dust suction ports 22. A connecting plate 15 is fixedly installed on the rear side wall of the inner cavity of the distribution box body 10, and each of the connecting plates 15 is hollow inside, and interface parts 23 are respectively provided on the left and right end surfaces of the connecting plate 15, and each of the interface parts 23 is respectively inserted into the corresponding dust suction port 22, and the upper end surface of the connecting plate 15 is fixedly connected with a cover plate 13, and strip holes 14 are distributed on the left and right sides of the cover plate 13;

[0026] When the distribution box is running, the air suction machine 19 is started to suction air, so that negative pressure is generated in each of the dust removal and heat dissipation pipes 16, thereby suctioning air through the heat absorption holes 17 on the surface, driving the air in the distribution box body 10 to be replaced, and absorbing the heat generated by the electrical appliances in the distribution box body 10. The dust attached to some electrical equipment fixedly installed on the cover plate 13 will also be in a certain active state due to the turbulence of the internal airflow, and will not cause dust accumulation. At the same time, it can also fall into the inner cavity of the connecting plate 15 through the strip holes 14, and be sucked into the dust removal and heat dissipation pipe 16 through the dust suction port 22, thereby achieving a dust removal effect.

[0027] It should be noted that, in order to facilitate the dust suction port 22 to absorb the dust falling into the inner cavity of the connecting plate 15, in this embodiment, a protrusion 24 is provided at the bottom of the inner cavity of the connecting plate 15, and both sides of the protrusion 24 are inclined.

[0029] In addition, in one embodiment, in order to facilitate the collection of dust and impurities absorbed by the dust removal and heat dissipation tube 16, an opening is provided on the front end face of the concentrated hollow plate 20 at the position of the dust removal and heat dissipation tube 16, and a collection frame 21 is slidably connected to the opening, so that the dust and impurities sucked into the dust removal and heat dissipation tube 16 fall into the collection frame 21 for collection.

[0030] During specific implementation, the electrical equipment is installed on the cover plate 13, and when the distribution box is running, the air sucker 19 is started to make the air sucker 19 suck air, so that negative pressure is generated in each of the dust removal and heat dissipation pipes 16, thereby sucking air through the heat absorption holes 17 on the surface, driving the air in the distribution box body 10 to be replaced, and absorbing the heat generated by the electrical appliances in the distribution box body 10. The dust attached to some electrical equipment fixedly installed on the cover plate 13 will also be in a certain active state due to the turbulence of the internal airflow, and will not cause dust accumulation. At the same time, it can also fall into the inner cavity of the connecting plate 15 through the strip holes 14, and be sucked into the dust removal and heat dissipation pipe 16 through the dust suction port 22, thereby achieving a dust removal effect.
