[0002] The distribution box is an important component in the power system, mainly used for the distribution and management of electric energy.

An operation panel 4 is fixedly installed at the center position on the front side of the box door 3. A handle 5 is fixedly connected to the right end on the front side of the box door 3.

[0021] Specifically, a heat dissipation elbow 6 is fixedly connected to the front end of the upper side of the box body 1, and a blower 7 is fixedly installed at the front end inside the heat dissipation elbow 6, effectively dissipating heat from the distribution box through air circulation. A plurality of ventilation openings 8 are respectively formed through the lower ends of the left and right sides of the box body 1, and a plurality of heat dissipation openings 9 are formed through the upper end of the rear side of the box body 1. An installation plate 10 is fixedly connected to the rear end inside the box body 1, and an installation cavity 11 is formed between the inside of the box body 1 and the front side of the installation plate 10. Temperature sensors 12 are fixedly installed at the upper ends of the left and right sides of the installation cavity 11 to detect the temperature inside the installation cavity 11 in real time and prevent the temperature from being too high. First dust-proof nets 13 are fixedly connected to the lower ends of the left and right sides of the installation cavity 11, and a second dust-proof net 14 is fixedly connected to the lower end of the heat dissipation elbow 6 after passing through the upper side of the box body 1, effectively preventing dust from entering the installation cavity 11 and damaging the electronic components.

[0022] Specifically, a plurality of heat conducting sheets 15 are fixedly connected to the front side of the installation plate 10 to effectively absorb heat. A plurality of mounting brackets 16 are fixedly connected between the front side of the installation plate 10 and the adjacent heat conducting sheets 15. A plurality of heat conducting rods 17 are fixedly connected to the rear side of the installation plate 10. The front ends of the heat conducting rods 17 penetrate through the rear side of the installation plate 10 and are fixedly connected to the rear sides of the heat conducting sheets 15, effectively conducting heat. The rear ends of the plurality of heat conducting rods 17 are fixedly connected to a heat dissipation plate 18. A liquid inlet pipe 19 is fixedly connected to the upper end of the right side of the heat dissipation plate 18, and a liquid discharge pipe 20 is fixedly connected to the lower end of the right side of the heat dissipation plate 18.
