ABSTRACT:
A heat dissipating fan includes a casing, a stator seat, a fan wheel, and a lid. The casing includes a compartment for receiving the fan wheel, and a bottom wall that defines the compartment has an axle tube formed thereon. The casing further includes an air outlet defined in an end edge thereof and communicated with the compartment. The fan wheel includes a number of blades and an axle that is rotatably received in the axle tube. The lid is engaged on top of the casing and includes an air inlet. Each blade includes an upper section extended beyond the air inlet, while a lower section of each blade is below the lid. When the fan wheel rotates, ambient air is driven into the casing via the air inlet of the lid to carry heat in the casing away via the air outlet of the casing. The heat dissipating fan may drive more air by increasing an active area of the blades with reduced noise.
