Problems solved by technology

[0007] Yet, because the rotor base 91 and the fan wheel 92 of the existing cooling fan 9 are all located in the airflow channel formed between the air inlet 931 and the air outlet 932, the airflow guided by the fan wheel 92 is also easily affected. The impediment of the rotor base 91 results in turbulent flow; moreover, the fan wheel 92 must be assembled with the rotor base 91, which also causes a lot of inconvenience in assembly and use.

Embodiment Construction

[0037] In order to make the above-mentioned and other objects, features and advantages of the present invention more comprehensible, the preferred embodiments of the present invention are specifically cited below, together with the accompanying drawings, as follows:

[0038] Please refer to image 3 and 4 As shown, the cooling fan according to the first embodiment of the present invention includes a fan frame 1 and a motor 2 . The fan frame 1 is a frame structure capable of allowing airflow to flow in a radial direction; the motor 2 is combined inside the fan frame 1 .

[0039] The fan frame 1 can be any hollow frame structure capable of accommodating the motor 2 and allowing air flow to be introduced and exported in a radial direction. Wherein the fan frame 1 at least includes a receiving portion 1a, a closing portion 1b and a side wall portion 1c, the receiving portion 1a is spaced opposite to the closing portion 1b, and the side wall portion 1c is located between the rece...

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...
