[0027] Through the above technical scheme, the heat dissipation fan 203 can be operated to draw in the outside air, and the filter 206 can block the impurities in the outside air. The heat dissipation fan 203 blows air into the cabinet 1 to dissipate the installed electrical components. When the filter 206 needs to be removed, the filter 206 is pulled out of the fan housing 201 by the handle. The operation is simple and convenient, and the disassembly time is short, which meets people's needs. By providing a plurality of mounting holes 304, the installation of electrical components is convenient. The heat generated by the electrical components when working is transferred to the heat dissipation fins 305 through the heat conduction plate 303. The heat dissipation fan 203 blows air to the heat dissipation fins 305, and the wind will take away the heat on the heat dissipation fins 305, which can dissipate heat and cool down well. The structure is simple and easy to use.

[0028] Specifically, a cabinet door 4 is hinged on the outer wall of the cabinet 1, and an exposed wire groove 5 is fixedly connected to the inner wall of the cabinet 1. A temperature sensor 6 is provided on the inner wall of the cabinet 1, and a lighting lamp 7 is installed on the inner wall of the cabinet 1. A support rod 8 is fixedly connected to the top of the cabinet 1, and a protective top 9 is fixedly connected to one end of the support rod 8.

[0029] Through the above technical scheme, a controller is arranged on the cabinet door 4, and an exposed wire groove 5 is arranged to facilitate the installation personnel to arrange the wires when installing electrical components. It is a common product on the market. A temperature sensor 6 is arranged to facilitate people to monitor the temperature inside the cabinet 1. A lighting lamp 7 is arranged to provide lighting for operators when installing or repairing at night. There are four support rods 8, which can well support the protective top 9. The protective top 9 plays a protective role to prevent falling objects from high altitude from damaging the filter 206 in the fan casing 201 or the cabinet 1. The outer wall of the cabinet 1 is provided with a heat dissipation groove to facilitate the dissipation of heat. The setting of the support frame 204 facilitates the sliding of the filter 206 and well supports the filter 206. There is a through groove in the middle of the support frame 204 to facilitate ventilation.

[0030] Specifically, the cabinet 1 forms a fixed structure with the fan housing 201 through the fixing bolt 202, and one end of the fixing bolt 202 is threadedly passed through the fan housing 201 and extends into the cabinet 1 for connection.

[0031] Through the above technical solution, there are multiple fixing bolts 202, which can well fix the fan housing 201 on the cabinet 1. There are two fan housings 201, which are symmetrically installed on the top of the cabinet 1.

[0032] Specifically, the fan housing 201 forms a sliding structure with the filter screen 206 through the slide groove 205, and one end of the filter screen 206 extends into the slide groove 205 for connection.

[0033] Through the above technical solution, the connection effect between the fan housing 201 and the slide groove 205 and the filter 206 is strengthened, which facilitates the sliding installation of the filter 206 in the slide groove 205. When disassembling, it is convenient for the operator to pull the handle to pull the filter 206 out of the slide groove 205. The outer wall of the filter 206 is provided with a handle.

[0034] Specifically, the filter screen 206 forms an elastic structure through the spring 208 and the round head 209 , and one end of the round head 209 extends into the circular groove 207 to be connected with the spring 208 .

[0035] Through the above technical solution, the connection effect between the filter 206, the spring 208 and the round head 209 is strengthened. The round head 209 is pressed against the slide groove 205 by the elastic force of the spring 208, so that the filter 206 can be inserted into the slide groove 205 for installation more stably and not easy to fall off.

[0036] Specifically, the cabinet 1 forms a fixed structure with the fixing frame 301 through the fastening bolt 302, and one end of the fastening bolt 302 is threaded through the fixing frame 301 and extends into the cabinet 1 for connection.

[0037] Through the above technical solution, the number of the fastening bolts 302 is multiple, which can well fix the fixing frame 301 on the cabinet 1, making it easy to install and disassemble.

[0038] Specifically, there are multiple heat dissipation fins 305 , and the multiple heat dissipation fins 305 are arranged on the heat conducting plate 303 at equal distances.

[0039] Through the above technical solution, by providing a plurality of heat dissipation fins 305, better heat dissipation is facilitated.

[0040] When in use, firstly, by providing a plurality of mounting holes 304, the operator can mount the electrical components on the heat conducting plate 303. By providing an open wire groove 5, it is convenient to arrange the wires when installing the electrical components. When in use, the device is connected to an external power supply, and the external power supply supplies power to the device. When the electrical components are working, the heat dissipation fan 203 works, and the heat dissipation fan 203 draws air from the outside. The air from the outside passes through the filter 206, and the filter 206 blocks impurities in the outside air. The heat dissipation fan 203 blows air into the cabinet 1 for heat dissipation. The heat generated when the electrical components are working is transferred to the heat dissipation fins 305 through the heat conducting plate 303. The wind blown by the heat dissipation fan 203 will blow onto the heat dissipation fins 305, and the wind will take away the heat on the heat dissipation fins 305, which can dissipate heat and cool down well. When it is necessary to disassemble When cleaning or replacing the filter 206, the operator pulls the filter 206 by pulling the handle, and pulls the filter 206 out of the slide slot 205 for disassembly. The operation is simple and convenient, and the disassembly time is short, which meets people's needs. During installation, the operator inserts the filter 206 into the slide slot 205 of the fan housing 201. During the insertion process, the inner wall of the slide slot 205 squeezes the round head 209, and the round head 209 moves to contract the spring 208. The spring 208 rebounds after contraction, causing the round head 209 to move. The round head 209 is pressed against the slide slot 205 by the elastic force of the spring 208, so that the filter 206 is installed more stably, the operation is simple and easy to use, and all the work is completed. The content not described in detail in this manual belongs to the existing technology known to professional and technical personnel in this field.
