The output end of the motor 10 is fixedly connected with the rotating shaft 11. The rotating shaft 11 is fixedly connected with the fan blade 12. The fan blade 12 is located above the horizontal plane. In this way, when dissipating heat, the motor 10 drives the rotating shaft 11 to drive the fan blade 12 to rotate at a high speed.
