Problems solved by technology

Please also see figure 2 , when the known fan frame 1 operates with fan blades (not shown in the figure), the airflow driven by the fan blades will generate turbulent flow at the air outlet of the fan frame 1, resulting in the airflow being unable to effectively dissipate heat against the heat source; Especially when operating under high back pressure, the airflow generated by the fan blade will generate turbulent flow on the curved surface of the stator blade 12, which will easily cause the fan blade to stall, the airflow will not be able to work effectively, and will generate relatively loud noise

Embodiment Construction

[0017] see image 3 , The fan with guide vanes of the present invention includes a fan frame 3 and an impeller set 2 arranged inside the fan frame 3, and the impeller set 2 has a plurality of upwardly inclined blades. The fan frame 3 includes a roughly square outer frame 30, a circular base 31 inside the outer frame, a plurality of stationary vanes 32 connecting the outer frame and the base, and a plurality of vanes 32 from the inner edge of the outer frame. The deflector 33 extends toward the center, wherein the vanes 32 and the deflector 33 are arranged at intervals.

[0018] Both the vane 32 and the air guide 33 are wing-shaped, but the air guide 33 is not in substantial contact with the base 31 to avoid excessively affecting the air volume output from the fan frame 3; in addition, the air guide 33 The height of the vane is preferably 1 / 4 to 3 / 4 of the height of the vane 32 .

[0019] Please also see Figure 4 When the impeller set 2 rotates to generate airflow, the airf...

Abstract

The present invention relates to a kind of fan frame with flow-guiding static blades and its fan. It is mainly characterized by that between static blades of said fan frame a shaped flow-guiding component is set, the combination of said static blade and said flow-guiding component can make air flow be more smoothly flowed, can reduce the production of turbulent flow, raise radiation effect and can reduce noise produced by turbulent flow.

Description

technical field [0001] The invention relates to a fan frame and a fan with flow guiding vanes, in particular to a fan frame and a fan with wing-shaped stationary vanes and flow guiding parts. Background technique [0002] Known axial flow fan frame such as figure 1 As shown, it includes an outer frame 10 , a base 11 inside the outer frame 10 and a plurality of vanes 12 connecting the outer frame 10 and the base 11 . Please also see figure 2 , when the known fan frame 1 operates with fan blades (not shown in the figure), the airflow driven by the fan blades will generate turbulent flow at the air outlet of the fan frame 1, resulting in the airflow being unable to effectively dissipate heat against the heat source; Especially when operating under high back pressure, the airflow generated by the fan blade will generate turbulent flow on the curved surface of the stator blade 12, which will easily cause the fan blade to stall, the airflow will not be able to work effectively,...
