The interior of the electric control box is not connected to the outside world, so as to prevent external dust or moisture from entering the electric control box and causing damage to the internal components. The heat dissipation fan 203 and the air intake hole 202 are provided to cooperate with each other, so as to increase the air circulation speed on the side of the heat dissipation fin 205, and the cross-sectional shape of the heat dissipation fin 205 is not set to be "S"-shaped, so as to increase the contact area between the heat dissipation fin 205 and the outside air, thereby improving the heat dissipation effect of the heat dissipation fin 205.

[0029] like Figure 3 As shown, an electric control box shell structure, the disassembly and assembly component 3 is used to complete the disassembly and installation of the shell heat dissipation component 2, the limit pin 304 and the second fixed block 306 form a locking structure, and the second fixed block 306 and the fan support frame 201 are integrated, the limit pin 304 and the first fixed block 301 and the first circular gasket 302 are all slidably connected, and the first fixed block 301 and the electric control box shell body 1 are integrated, by pulling the limit pin 304, the shell heat dissipation component 2 can be installed and disassembled, and then it is convenient to clean the internal heat dissipation fins 205 or repair the heat dissipation fan 203, and it is convenient to prevent dust from accumulating on the heat dissipation fins 205 or the heat dissipation fan 203 cannot rotate normally, affecting the heat dissipation effect, and the structure is simple and easy to operate.

[0030] like Figure 4 and Figure 5As shown, an electric control box shell structure, the electric control box sealing component 4 includes a rotating shaft 401, and a sealing door plate 402 is rotatably connected to the side of the rotating shaft 401, and a sealing ring 403 is fixedly connected to the inner wall of the sealing door plate 402, a clamping hole 404 is opened on the other side of the sealing door plate 402, and a clamping block 405 is tightly fitted on the outer wall of the clamping hole 404, a rotating pin 406 is fixedly connected to the side of the clamping block 405, and the end of the rotating pin 406 is rotatably connected to a rotating base 407, the clamping block 405 forms a rotating structure with the rotating base 407 through the rotating pin 406, and the shape of the clamping block 405 is set to be a rectangular parallelepiped, and the cross-sectional area of ​​the clamping block 405 is smaller than the cross-sectional area of ​​the clamping hole 404, and a sealing ring 403 is arranged between the sealing door plate 402 and the electric control box shell body 1, so as to enhance the sealing of the electric control box and prevent external dust or moisture from entering the interior of the electric control box and affecting the service life of its internal electrical components.

[0031] Working principle: the heat generated by the electrical components inside the electric control box housing body 1 during operation will be conducted to the heat dissipation fins 205 that fit tightly to the electric control box housing body 1. The heat dissipation fins 205 will also dissipate the heat to the surrounding air through heat exchange. The temperature relay 204 installed on the inner wall of the heat dissipation fan 203 can monitor the temperature inside the fan support frame 201 in real time. When the temperature reaches a preset threshold, the temperature relay 204 will control the start of the heat dissipation fan 203 to work. The rotating blades of the heat dissipation fan 203 will discharge the hot air inside the fan support frame 201 to the outside. At the same time, new air from the outside will enter the fan support frame 201 through the air inlet holes 202 at the upper and lower ends of the fan support frame 201, and the incoming airflow will flow through the sides of the heat dissipation fins 205 and be discharged again through the heat dissipation fan 203, forming an airflow cycle. During the cycle, the heat on the heat dissipation fins 205 is taken out.

[0032] After a long period of operation, if dust adheres to the heat dissipation fins 205, or the heat dissipation fan 203 is damaged and needs to be disassembled for maintenance, the device only needs to pull the limit pin 304 to disengage the end of the limit pin 304 from the second fixing block 306. At this time, the limit fixation of the limit pin 304 is lost, and the fan support frame 201 can be removed, and then the heat dissipation fins 205 can be cleaned or the heat dissipation fan 203 can be repaired. If it is necessary to open the main body 1 of the electric control box shell to inspect the internal parts, it is only necessary to rotate the locking block 405 to align the locking block 405 with the locking hole 404 so that the locking block 405 can pass through the locking hole 404, and then the sealing door panel 402 can be rotated open.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
