[0025] like Figure 1-5 It is a schematic diagram of the structure of a power distribution cabinet with temperature control in a preferred embodiment of the utility model. In this embodiment, a power distribution cabinet with temperature control includes a cabinet body 1, a mounting cavity 6 is opened in the cabinet body 1, and a connecting block 12 is fixedly installed around the rear end of the inner wall of the mounting cavity 6. A mounting plate 9 is fixedly installed on the connecting block 12, so that a space is formed between the mounting plate 9 and the inner wall of the mounting cavity 6, which is convenient for heat to be dissipated from the ventilation hole 11. In addition, a first heat dissipation port 7 and a second heat dissipation port 8 are respectively opened on both sides of the inner wall of the mounting cavity 6, and a heat dissipation device is provided in the first heat dissipation port 7 and the second heat dissipation port 8. 2, and a plurality of ventilation holes 11 are opened on the rear end surface of the inner wall of the installation cavity 6, and a dustproof net is installed in the ventilation hole 11. Since the power distribution cabinet will be installed against the wall, the heat cannot be dissipated from the ventilation hole 11, so a fixing block 13 is fixedly connected to the rear end surface of the outer wall of the cabinet body 1, and a fixing plate 3 is fixedly connected to the fixing block 13, so that a space is formed between the outer wall of the cabinet body 1 and the fixing plate 3, which is convenient for heat to be dissipated from the ventilation hole 11. Combined with the design of the above structure, the temperature inside the power distribution cabinet body is cooled by the cooperation of the ventilation hole 11 and the heat dissipation device 2, thereby improving the stability and safety of the power distribution cabinet body.

[0026] In this embodiment, a temperature sensor 10 is fixedly installed on the top of the inner wall of the installation cavity 6 to monitor the temperature change inside the installation cavity 6. The door body 4 is fixedly connected to the front end of the outer wall of the cabinet body 1 through a hinge.

[0027] In this embodiment, the first heat dissipation port 7 and the second heat dissipation port 8 are staggered in design, and the first heat dissipation port 7 is located above the second heat dissipation port 8. At the same time, connection holes 14 are opened on the outer wall of the cabinet 1 around the first heat dissipation port 7 and the second heat dissipation port 8, and a controller 5 is fixedly installed on the outer wall of the cabinet 1 just below the first heat dissipation port 7 to play a control role.

[0028] In this embodiment, the heat dissipation device 2 includes a fixing frame 22, a baffle 21 and an exhaust fan 23. The fixing frame 22 is arranged on the inner wall of the installation cavity 6, the baffle 21 is arranged on the outer wall of the cabinet 1, and a dust net is installed in the baffle 21. The fixing frame 22 is threadedly connected to the baffle 21 by bolts passing through the connecting hole 14. The setting of this structure strengthens the connection strength between the fixing frame 22 and the baffle 21, and also reduces the parts required for installation. An exhaust fan 23 is fixedly installed between the fixing frame 22 and the baffle 21, and the heat in the cabinet 1 can be discharged from both sides of the cabinet 1 through the exhaust fan 23.

[0029] In this embodiment, the controller 5 is electrically connected to the temperature sensor 10 and the exhaust fan 23. Through this structural design, the temperature inside the cabinet 1 is monitored in real time by the temperature sensor 10 and transmitted to the controller 5 in real time. The controller 5 automatically controls the speed of the exhaust fan 23 according to the set parameters.
