[0041] Working principle:

[0042] When the power distribution cabinet body 1 is used, the heat dissipation exhaust fan 2 is installed at the bottom of the plurality of electronic components 101, and the air guide fan 202 is installed at the top of the plurality of electronic components 101. The heat dissipation exhaust fan 2, the plurality of electronic components 101 and the air guide fan 202 are all spaced apart from the inside of the power distribution cabinet body 1, ensuring that air can flow and be discharged when the heat dissipation exhaust fan 2 and the air guide fan 202 blow and guide air to dissipate heat. When the plurality of electronic components 101 are working, the heat generated will be dispersed in the power distribution cabinet body 1. At this time, the heat dissipation exhaust fan 2 and the air guide fan 202 are started to work. The heat dissipation exhaust fan 2 sucks in air from the air inlet pipe 201 to generate negative pressure and blow air to the electronic components 101, blowing the heat generated by the electronic components 101 upwards to the air guide fan 202. The air guide fan 202 absorbs the blowing heat gas and blows it out of the air outlet hole 203, so that the heat gas can be discharged from the power distribution cabinet body 1 to the outside. Through air flow, the heat is taken away. The heat dissipation exhaust fan 2 can generate an air flow from bottom to top in the power distribution cabinet body 1, and the air guide fan 202 can absorb the hot air flow and discharge it from the power distribution cabinet body 1 to the outside. This speeds up the circulation of air in the power distribution cabinet body 1, preventing heat from accumulating around the electronic components 101, and improving the heat dissipation and cooling effect of the electronic components 101 in the power distribution cabinet body 1.

[0043] The dust cover 204 and the dust screen 205 can prevent dust from entering the inside of the power distribution cabinet body 1 from the air outlet hole 203, prevent the electronic components 101 inside the power distribution cabinet body 1 from accumulating dust, and avoid poor contact of the electronic components 101 during use. When the dust screen 205 is used, the dust screen 205 accumulates dust in the mesh, and the dust cover 204 can be removed from the top of the power distribution cabinet body 1 for cleaning and washing to prevent dust from blocking the mesh of the dust screen 205, and to ensure that the heat inside the power distribution cabinet body 1 can be normally dissipated and discharged.

[0044] During use of the power distribution cabinet body 1, the dry bag is placed in the storage box 3, and the air-permeable net 301 is installed outside the storage box 3 to prevent the dry bag from falling out. The dry bag is made of silica gel desiccant material, which can absorb the moisture inside the power distribution cabinet body 1. The dry bag helps to maintain a dry environment inside the power distribution cabinet body 1, and prevents moisture from causing metal parts to rust and corrode the conductors, contactors and other metal parts inside the power distribution cabinet body 1.
