[0017] (Three) beneficial effects

[0018] Compared with the prior art, the energy-saving heat dissipation fan has the following beneficial effects:

[0019] 1. The energy-saving heat dissipation fan, when the support shaft is running, can drive the guide disc to rotate, at this time the guide disc drives the guide vane to rotate, at this time the arc-shaped guide vane drives the air inlet in the first machine frame, so that the air passes through the through hole to promote the air inlet process, which can make the internal heat dissipation component run quickly, reduce the useless work when inhaling, save the energy waste during operation, and the support shaft can drive the connecting frame to rotate synchronously with the guide cylinder, so as to cooperate with the guide vane and the guide disc to rotate quickly.
