Abstract
A slim fan structure includes a fan frame, a top cover closed to a top of the fan frame to define a receiving space in the fan frame, a stator assembly mounted in the receiving space, and a hub fitted around the stator assembly. The fan frame has opposite first and third sides forming an air inlet and an air outlet, respectively, and opposite second and fourth sides having a first and a second side wall formed thereon, respectively. The first side wall includes a protruded portion laterally extended toward the air inlet, and the second side wall includes a stop portion located adjacent to the air outlet. With the air inlet and the air outlet formed on two lateral sides of the fan frame, the slim fan structure has an effectively reduced overall thickness and does not produce noise during operation to largely upgrade the operational performance thereof.
