[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Reference Figure 1-4 A moisture-proof, dense busbar trunking system includes a busbar trunking body 1. The busbar trunking body 1 has an internal ventilation cavity 7. Heat dissipation plates 5 are installed on both sides of the ventilation cavity 7. Several conductive copper busbars 6 are installed inside the heat dissipation plates 5. Several fixing bolts 4 are threaded onto one side of the heat dissipation plates 5, with one end of each fixing bolt 4 located on the outer surface of the busbar trunking body 1. Ventilation openings 10, communicating with the ventilation cavity 7, are opened on both sides of the upper surface of the busbar trunking body 1. A lower ventilation mesh 8 is installed between the ventilation openings 10 and the ventilation cavity 7. An upper ventilation mesh 11 is installed above the ventilation openings 10. A moisture-absorbing port 9 is installed on one side of the ventilation openings 10. Moisture-absorbing boxes 3, corresponding to the moisture-absorbing ports 9, are installed on both sides of the internal interior of the busbar trunking body 1. Through this design, the moisture-absorbing boxes 3 can absorb moisture entering the ventilation openings 10 from the external environment, keeping the air inside the ventilation cavity 7 dry, preventing damage to the conductive copper busbars 6 from moisture, and improving moisture resistance and safety.

[0026] Reference Figure 1-2The moisture-absorbing box 3 contains a moisture-absorbing material 13. A sealing cover 2 is provided on the upper surface of the moisture-absorbing box 3. A pull rod 12 is provided on the upper surface of the sealing cover 2. Insert plates 15 are provided on both sides of the lower surface of the sealing cover 2. The busbar trunking body 1 has a slot 14 corresponding to the insert plate 15. The insert plate 15 is inserted into the slot 14. The sealing cover 2 can be pulled by the pull rod 12 to remove the insert plate 15, which facilitates the replacement of the moisture-absorbing material 13, improves convenience and maintains the working effect of the moisture-absorbing box 3.

[0027] Reference Figure 2-3 A magnetic block 16 is installed on the lower surface of the insert plate 15, and a magnetic block 17 corresponding to the magnetic block 16 is installed inside the slot 14. The magnetic attraction between the magnetic block 16 and the magnetic block 17 improves the stability of the insert plate 15 when it is inserted into the slot 14.

[0028] Reference Figure 1 and Figure 4 A waterproof sleeve 18 is fitted onto the outer surface of the conductive copper busbar 6. The waterproof sleeve 18 can protect the conductive copper busbar 6, improve its waterproof and moisture-proof ability, avoid damage from water vapor, and extend its service life.

[0029] Reference Figure 1 and Figure 4 The outer surface of the heat sink 5 is coated with polyurethane coating, which has good water resistance and corrosion resistance. After drying, it forms a smooth surface, which helps to reduce the adhesion of moisture and thus avoids the adverse effects of water vapor on the conductive copper busbar 6.

[0030] The implementation principle of a moisture-proof dense busbar trunking embodiment of this application is as follows:

[0031] When the external environment is relatively humid, the moisture-absorbing box 3 can absorb the moisture entering the ventilation port 10, keeping the air inside the ventilation cavity 7 dry, preventing moisture from damaging the conductive copper busbar 6, and improving moisture resistance and safety. After the moisture-absorbing material 13 has been absorbing moisture for a long time, the sealing cover 2 can be pulled by the pull rod 12 to remove the inside of the insert plate 15, making it convenient to replace the moisture-absorbing material 13. After replacement, under the action of gravity, the insert plate 15 is inserted into the slot 14. The magnetic attraction between the magnetic block 16 and the magnetic block 17 further improves the stability of the insert plate 15 inserted into the slot 14.
