Abstract
Disclosed is a fan with multilayer fan blades, including a fan frame and a motor. Multilayer fan blades are arranged in the fan frame; the multilayer fan blades are connected to the motor, and the multilayer fan blades are arranged with at least two fan blade connection rings. According to the above solution, by utilizing the design of blade shapes and the number of different curved surfaces of the multilayer fan blades, an inner layer has a faster wind speed than an outer layer, and the fan is changed from a smooth wind suction flow field to a spiral flow field with a funneling effect, reducing the attenuation of long-distance wind flow and improving the heat dissipation efficiency at a far working point.
