摘要
A heat dissipation fan blade structure and a heat dissipation fan thereof. The heat dissipation fan blade structure includes a main fan blade and a subsidiary fan blade. The main fan blade has a root section and a free end section. The root section is connected with a hub. The free end section radially extends in a direction away from the hub. A main body section is formed between the root section and the free end section. The subsidiary fan blade extends from the free end section of the main fan blade toward the root section of the main fan blade to the main body section. The subsidiary fan blade and the main fan blade together form a loop structure defining a flow way between the main fan blade and the subsidiary fan blade.
