Fan, motor and blade thereof

Abstract

A turbine wheel and a motor driven by a stator structure, and a fan having this turbine wheel. The turbine wheel includes a conduction case, wheel hub and a plurality of flabellums. At least one side of the stator structure is covered by the conduction case, the wheel hub covers the conduction case, and at least one air gap is provided between the wheel hub and the stator structure. An opening is provided on top of the wheel hub, which exposes part of the conduction case top. At least one air current passage is formed between inner wall of the wheel hub and outer surface of the conduction case, which is provided with at least one air inlet and outlet. The air inlet communicates with the opening, and the outlet communicates with the air gap. The flabellum rings are provided on periphery of the wheel hub. An air current passage is provided between inner wall of the wheel hub and the conduction case, heat produced by operation of the stator structure is conducted to air current passing through the air current passage via the conduction case, thereby being brought out of the fan, motor and the turbine wheel by the air current, hence, self-dissipation effect and operation efficiency of the fan, motor and the turbine wheel can be improved. Because there is no opening on top of the conduction case, damage of inner elements of the fan and the motor for invasion of foreign matters can be avoided.

Description

Technical field [0001] The present invention relates to fans, motors and impellers, in particular to fans, motors and impellers with excellent heat dissipation effects. Background technique [0002] With the rapid development of electronic products in the direction of high performance, high frequency, high speed and thinness, the heating temperature of electronic products is getting higher and higher, which is prone to instability and affect product reliability. Therefore, existing electronic products Fans are often used as heat sinks. [0003] Please refer to Figure 1. As shown in FIG. 1, a conventional fan 1 includes an impeller 11, a motor 12 and a fan frame 13. The impeller 11 includes a hub 111 and a plurality of fan blades 112 circling around and connected to the periphery of the hub 111. The motor 12 is accommodated in the hub 111, and is connected to and drives the impeller 11 to rotate. The impeller 11 and the motor 12 are installed in the fan frame 13. To protect the mo...
