The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
 Reference Figure 1-3 , An outdoor heat dissipation and dustproof power distribution cabinet, comprising a right cabinet door 9, a cabinet body 14, a left cabinet door 16 and a controller outer box 21. The top of the cabinet 14 is provided with a top plate 4, and the surface of the top plate 4 is provided with LED lights 6, A left cabinet door 16 and a right cabinet door 9 are respectively arranged on both sides of the front face of the cabinet body 14, a controller outer box 21 is arranged on the front face of the left cabinet door 16, and an observation window 10 and a top plate are arranged on the front face of the right cabinet door 9 4 A temperature sensor 5 is provided on the lower surface. The cabinet body 14 is respectively connected to the left cabinet door 16 and the right cabinet door 9 through a hinge 8. A filter screen 1 is provided on one side of the inner wall of the cabinet body 14 and cold air is provided on the right side of the filter screen 1 The drying chamber 3 is provided on the right side of the air cooler 2, and the condensing coil 7 is provided on one end of the inner wall of the cabinet 14, the cooling fin 12 is provided under the condensing coil 7, and the dust collecting plate 15 is provided at the bottom of the cabinet 14 to collect A dust box 13 is provided on the lower side of the dust plate 15.
 A control panel 19 is provided on the front face of the controller outer box 21. The surface of the control panel 19 is provided with a display screen 18 and a control button 20. The display screen 18 is located above the control button 20. The rear face of the cabinet 14 is evenly provided with heat dissipation holes 22 The inside of the heat dissipation hole 22 is provided with a filter plate 23, the left cabinet door 16 is connected with the right cabinet door 9 through an electromagnetic lock 17, the top plate 4 gradually increases from the front and rear sides to the middle, and the inner wall of the cabinet 11 is provided with a layer of temperature insulation layer 11 .
 In the present invention, since the left cabinet door 16 and the right cabinet door 9 are provided with an electromagnetic lock 17 on the inner wall side, and a control button 20 is provided under the controller outer box 21, the staff can use the card to open the cabinet 14 and the staff can pass The observation window 10 can be used to observe whether there is any problem with the internal circuit. The filter screen 1, the air cooler 2 and the drying chamber 3 are arranged on the inner wall of the cabinet 14 to ensure that the air cooler 2 avoids the introduction of impurities, dust and moisture during the working process. Dust and water vapor corrode the circuit. Through the arrangement of the air cooler 2, the dust collecting plate 15 and the dust collecting box 13, the dust inside the cabinet 14 can be collected on the dust collecting plate 15 through electrostatic dust removal and slide down into the dust collecting box 13. It is convenient for the staff to collect and clean up in time. The temperature sensor 5, the condensing coil 7, the controller outer box 21 and the cooling fin 12 are provided on the inner wall of the cabinet 14. When the temperature sensor 5 senses that the temperature reaches a certain value, the controller outer box 21 Arrange the refrigeration fins 12 to work, and cool and dissipate heat inside the cabinet 14. The invention has good heat dissipation effect, good dustproof effect, and enhances the safety of the power distribution cabinet.
