An air guiding apparatus includes a duct, a guiding unit, and a turbine. The duct defines a through-hole therein to form an inside wall. The duct includes an inlet, and an outlet. The guiding unit is mounted to the inside wall of the duct and located in the through-hole of the duct to divide the through-hole of the duct into an expanding part at the inlet of the duct, and a narrow flow channel connecting the inlet and the outlet of the duct. The turbine is mounted to the duct and located in the flow channel.
