Abstract

A radiator fan comprises a frame and a motor, wherein the frame comprises a carrying part, an enclosed part and a side wall part, wherein an accommodation space is formed among the carrying part, the enclosed part and the side wall part; and at least one side air inlet and at least one side air outlet are arranged on the side wall part; the motor is combined in the accommodation space of the frame, the motor comprises a stator and an impeller (namely a rotor), the impeller is rotatably combined with the stator, a hub and a plurality of blades are arranged on the impeller, the impeller is provided with a top surface, the top surface faces to the enclosed part, between the top surface and the enclosed part, a lateral flow passage is formed in the accommodation space through partitioning, and each blade is positioned inside the lateral flow passage. Therefore, the phenomenon of turbulence is effectively prevented, and the radiating effect is improved.

Description

technical field

[0001] The present invention relates to a heat dissipation fan, in particular to a heat dissipation fan capable of introducing and exporting air flow in a radial direction on the radial direction of the fan wheel. Background technique

[0002] Existing heat dissipation fans generally include two types: axial flow heat dissipation fans and blower heat dissipation fans. Among them, the axial flow cooling fan has an axial air inlet and an axial air outlet opposite to each other in the axial direction, so that the airflow can be introduced through the axial air inlet, and then the airflow can be exported through the axial air outlet to provide heat dissipation. ; Also, the blast cooling fan has an axial air inlet in the axial direction, and a radial air outlet in the radial direction, so that the airflow can be introduced through the axial air inlet, and then pass through the radial air outlet side. The guide guides the airflow, but also has the function of cool...
