Embodiment 1

[0056] Please refer to figure 1 , the fan in the embodiment of the present application first includes a driving structure.

[0057] Specifically, in the embodiment of the present application, the driving structure provides rotational power for the fan. The force generated by the magnetic field in the driving structure on the winding has a great influence on the rotational speed of the fan blade structure 1 . If the force is large, the fan will rotate faster, and if the force is small, the fan will rotate slowly. Therefore, the control of the fan speed can be realized by controlling the drive structure.

[0058] In a specific implementation process, the driving structure may be a DC motor, a DC brushless motor, or the like. After the direct current or alternating current in the electronic equipment passes through the transformer circuit and / or the rectification circuit, under the control of the control circuit, it is input into the drive structure, so that the drive structur...

Embodiment 2

[0115] The electronic equipment in the embodiment of this application includes:

[0116] device body.

[0117] Specifically, the device body may be a host computer of a desktop computer, a keyboard body of a notebook computer, a display body of an all-in-one computer, and the like. The main body of the device includes at least one electronic component, and after the working time of the at least one component exceeds a threshold time, the surface temperature of the at least one electronic component exceeds a threshold temperature.

[0118] Since electronic components need to be connected to electric energy to work, and electronic components cannot use 100% of the incoming electric energy, therefore, the unused electric energy will be converted into internal energy of electronic components and maintained in the form of heat release. energy balance. Therefore, the threshold time in the embodiment of the present application can be 20 minutes, 30 minutes, etc., and the threshold ...
