Abstract: A fan blade structure comprises primarily an axle seat and plural vanes. Each vane is connected to the axle seat and includes a vane body. The vane body is provided an air pressure structure which is extended from the axle seat, and an air flow structure which is extended from an end of the air pressure structure. The angle of air pressure structure is smaller than that of air flow structure. By the air pressure structure, turbulent air can be pushed to a farther distance. On the other hand, as the tilt angle of air flow structure is larger than the angle of air pressure structure, the range of push to the turbulent aft can be increased, so as to improve the heat dissipation effect.

Abstract: A heat dissipation structure includes primarily plural cooling fins. A flow space for air flow is defined between every two cooling fins, and at least a through-hole which is connected with the flow space is defined on each cooling fin. Therefore, the air speed can be increased, so that heat will not be accumulated easily and can be removed out rapidly, thereby improving the heat removal efficiency of the heat dissipation structure. In addition, as each cooling fin is provided with plural through-holes, the weight of entire finished product can be decreased indirectly.
