High temperature can affect the performance of the components, shorten the service life of the components, and even cause the components to malfunction. Therefore, a fan is needed to set up in the power supply cabinet for heat dissipation. The existing fan is installed at the air inlet position in the power supply cabinet, and the fan blows air inward and directly discharges through the outlet.

A protective cover is provided on the installation hole of the base to form a containing cavity with the installation hole. A heat dissipation fan is arranged in the containing cavity. The protective cover prevents dust or water from entering the electric appliance cabinet. The side surface of the protective cover is provided with a heat dissipation hole, which also communicates with the containing cavity. Hot air in the electric appliance cabinet is discharged from the electric appliance cabinet through the installation hole, the containing cavity and the heat dissipation hole under the action of the heat dissipation fan.

[0056] Example 2

[0057] The communication cabinet with the flow guiding function further comprises a processor, the processor is configured with a control system for controlling the movement of the electric cylinder 200, and the control system comprises:

[0058] An input module for inputting a cleaning instruction;

[0059] A work module comprising:

[0060] An adjustment mode for controlling the electric cylinder 200 to stretch and retract to adjust the angle of the flow guide plate 205;

[0061] A cleaning mode for controlling the electric cylinder 200 to stretch and retract to clean the second shell 104;

[0062] Further comprising dividing the stroke of the electric cylinder 200 into regions, including an adjustment section and a cleaning section, wherein the adjustment section represents the movement interval of the output end of the electric cylinder 200 when the moving frame 203 is on the top of the guide block 201, and the cleaning section represents the movement interval of the output end of the electric cylinder 200 when the piston 303 moves in the air pipe 300;

[0063] The input module comprises a judgment strategy, based on which the working mode of the electric cylinder 200 is changed, when no cleaning instruction is obtained, the electric cylinder 200 enters the adjustment mode, and when a cleaning instruction is obtained, the electric cylinder 200 enters the cleaning mode;

[0064] The adjustment mode comprises obtaining the rotation angle of the deflector 205 and the temperature of the hot air flow blown by the fan 108, obtaining the rotation angle of the deflector 205 based on the temperature of the hot air flow, and controlling the electric cylinder 200 to move in the adjustment section, when the temperature of the hot air flow is high, driving the electric cylinder 200 to control the deflector 205 to rotate to one side to enhance heat dissipation, and when the temperature of the hot air flow is low, driving the electric cylinder 200 to control the deflector 205 to rotate to the other side to enhance the flow rate of the hot air flow.

[0065] The cleaning mode comprises controlling the electric cylinder 200 to move in the cleaning section, and further comprises controlling the electric cylinder 200 to perform one-time reciprocating motion in the cleaning section when the cleaning instruction is obtained.

[0066] The implementation principle of the communication cabinet with the deflection function in the embodiment is as follows: when working, the fan 108 blows out the hot air in the communication cabinet to the fifth deflection surface 107, the hot air flow enters the space on one side of the second deflection surface 102 along the fourth deflection surface 106 and the third deflection surface 105, and is discharged under the guidance of the first deflection surface 101.

[0067] When the temperature is low, the electric cylinder 200 starts to extend and drives the guide block 201 to move, in the moving process of the guide block 201, the spring 207 abuts against the fixed block 206 to make the moving frame 203 always abut against the guide block 201, so that the moving frame 203 moves and drives the deflector 205 to move through the connecting rod 204 in the moving process, the gap between the deflector 205 and the second deflection surface 102 is reduced, the hot air flow enters the second deflection surface 102 through the action of the deflector 205, and is discharged along the first deflection surface 101, and because the gap between the deflector 205 and the second deflection surface 102 is reduced, the speed of the air flow is increased, and for the same reason, when the temperature is high, the electric cylinder 200 starts to contract, so that the gap between the deflector 205 and the second deflection surface 102 is increased, thereby enhancing the heat dissipation effect.

[0068] When it is needed to clean the first shell 100, the electric cylinder 200 is controlled to extend, when the stop rod 307 driven by the electric cylinder 200 abuts against the connecting frame 305, the electric cylinder 200 continues to extend, at this time, the moving frame 203 abuts against the output end of the electric cylinder 200, in this state, the deflector 205 keeps the maximum inclination angle, that is, the gap between the deflector 205 and the second deflection surface 102 is the smallest, the electric cylinder 200 pushes the piston 303 to move while continuing to move, the piston 303 squeezes the air in the air pipe 300 in the moving process, and the air enters the connecting pipe 406 through the connecting head 407, then enters the inner pipe body 402 through the air inlet groove 404 and the adapter cavity 405, and is blown to the second shell 104 through the air outlet formed by the straight groove 401 and the overlapping section of the spiral groove 403.

[0069] During the movement of the piston 303, the air pipe 300 rotates under the double action of the guide protrusion 302 and the guide groove 304, and in the process of rotation, the first transmission assembly 408 drives the rotating shaft 409 to rotate, the rotating shaft 409 drives the inner pipe body 402 to rotate through the second transmission assembly 411, the inner pipe body 402 drives the helical groove 403 to rotate in the process of rotation, and the helical groove 403 moves in the coincident section of the straight groove 401 in the process of rotation, so that the air outlet moves to clean different areas of the second shell 104.

[0070] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and all of them should be covered in the scope of the claims of the present application.
