[0016] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] In the description of this utility model, it should be noted that the terms "upper," "lower," "left," "right," "front," "rear," "inner," "outer," "vertical," and "horizontal," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] like Figure 1-2 This is a schematic diagram of a fan blade with high-efficiency heat dissipation according to a preferred embodiment of the present invention. In this embodiment, a fan blade with high-efficiency heat dissipation includes a wheel housing 1, a disc 2 disposed on the outer wall of the wheel housing 1, and a wheel arch 3 disposed on the outer wall of the disc 2. The wheel arch 3 and the disc 2 are connected by an outer impeller 4, which dissipates heat. The disc 2 and the wheel housing 1 are fixedly connected by several connecting ribs 6, with an included angle of 72° between two connecting ribs 6. This structural design increases the connection strength between the disc 2 and the wheel housing 1, making the fan blade rotate more stably. The setting of the connecting ribs 6 enhances the connection between the disc 2 and the wheel housing 1. At the same time, the opening 7 formed between two connecting ribs 6 can assist the heat dissipation effect of the outer impeller 4 through the opening 7, thereby achieving the purpose of rapid heat dissipation.

[0019] In this embodiment, a first inner impeller 5 and a second inner impeller 10 are respectively installed on the top and bottom of the surface of the disk 2. The positions of the first inner impeller 5 and the second inner impeller 10 are staggered. Both the first inner impeller 5 and the second inner impeller are composed of a number of inner blades 9. The number of inner blades 9 of the first inner impeller 5 and the second inner impeller 10 are different. The inner blades 9 are designed to surround the disk 2. When the inner impeller 5 is rotated by the wheel housing 1, it guides the airflow to the outer impeller 4 and the opening 7. The arrangement of the inner blades 9 of the first inner impeller 5 and the second inner impeller 10 increases the air volume and air pressure, and improves the heat dissipation effect.

[0020] In this embodiment, the outer impeller 4 is composed of a plurality of outer blades 8, and the outer blades 8 are designed to surround the wheel arch 3.

[0021] In this embodiment, the number of outer blades 8 is greater than the number of inner blades 9. This structural design allows the inner blades 9 to rotate and guide the airflow to the outer blades 8. By using a larger number of outer blades 8, the airflow and wind speed are increased, thereby achieving a rapid heat dissipation effect.

[0022] The above description provides a more detailed explanation of the present invention in conjunction with specific embodiments. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present invention.
