Abstract: A fan impeller structure includes an annular body. The annular body has a top section and a receiving space. At least one first bending section is formed between the top section and the annular body. At least one recess is formed at the first bending section. At least one flow guide hole is formed between the first bending section and the recess in communication with the receiving space. In operation, the airflow conducted into the receiving space is increased. Moreover, no matter whether the fan impeller structure is clockwise rotated or counterclockwise rotated, the airflow can be conducted into the receiving space through the flow guide hole. Accordingly, the heat dissipation effect will not be affected by the rotational direction of the fan impeller structure.

Abstract: A hub structure includes an annular body and a flow guide unit. The annular body has a top end and a receiving space. The flow guide unit is disposed at the top end of the annular body. At least one raised section is formed on one face of the flow guide unit opposite to the receiving space. A motor set is disposed in the receiving space. When the motor set operates, the annular body and the flow guide unit are driven to rotate around the axis of a shaft rod. At this time, airflow is conducted through the raised section into the receiving space to dissipate the heat generated by the motor set. Accordingly, the temperature of the motor set can be effectively lowered to prolong the lifetime of the motor set.
