New description: Supplement ^_____ [New technical field] This creation is about a fan frame with a guide vane and a fan, especially for a kind of guide flow extending on the wing vane Fan frame and fan. [Prior Art] As shown in Fig. 1, the conventional axial fan fan frame includes an outer frame (1〇), a base (Π) in the = frame (10), and a plurality of connections to the outer frame ( 10) The vane (12) with the base (u). Please also refer to Fig. 2, when the fan frame (1) is operated with the fan blade (2), the airflow driven by the blade (2) will be in the fan frame (1) due to the rotational inertia. Turbulence is generated at the air outlet, and the air volume cannot be concentrated, which causes the airflow to be unable to effectively dissipate heat from the heat source; especially when operating under high back pressure, the airflow generated by the fan blades will generate turbulence on the surface of the vane (12) ( As shown in Figure 3, it is easy to cause the fan blade (2) to stall, and the airflow cannot work effectively' and produce a large β-sound. This creation proposes a fan fan frame with a guide vane for the above-mentioned lack, which can effectively guide the flow of airflow so that the airflow does not cause turbulence. The following is a brief description of the creation. [New content] The main purpose of the present invention is to provide a fan frame and a fan with a guide vane, which extends at least one flow guide in a circumferential direction on each vane surface, the side wall of the guide member The flow direction of the airflow can be changed, and the airflow of the air outlet is concentrated to dissipate heat for the heat source; in addition, the flow guide has a rectifying effect, which can reduce the generation of the turbulent flow field on the air outlet and the curved surface, and can reduce The noise generated by turbulence. To achieve the above object, the fan of the present invention includes a frame and an impeller set disposed inside the frame. The fan frame includes an outer frame, a base in the outer frame, a plurality of vanes connecting the outer frame and the base, and a plurality of at least one flow guiding member extending circumferentially on the vanes. The vane system has a wing shape and includes an upper curved surface and a curved surface. The flow guiding member may extend from the upper curved surface or may extend from the lower curved surface without contacting adjacent vanes. The flow guiding member uses its side wall to change the flow direction of the airflow by the fan blade M287387, and can concentrate the airflow on the heat source to dissipate the turbulent flow field on the wind tunnel and the vane surface of the factory. It can reduce the noise generated by turbulence. In addition, the design of the flow guiding members can also prevent external foreign matter from entering the air outlet of the fan frame to protect the internal components of the fan frame. The above and other objects, features, and advantages of the present invention will become more apparent and obvious. The following detailed description of the preferred embodiments, together with the accompanying drawings, will be described in detail as follows: [Embodiment] 第And in the figure 5, the fan frame of the present invention has a square-shaped outer frame (30), a circular base (3丨) in the outer frame, and a plurality of connecting the outer frame and The stationary vane (32) of the base and the plurality of at least one flow guiding member (33) extending circumferentially on the vanes, the present embodiment extends two guiding members on each vane (32) (33) To explain. The vane (32) is in the shape of a wing, and includes an upper curved surface (321) and a lower curved surface (322). The flow guiding member (33) mainly extends from the top of the lower curved surface (322); The deflector (33) does not make substantial contact with the adjacent vanes (32) to avoid occupying too much space and not facilitating the flow of the airflow. Referring to Figures 6 and 7, when a leaf (4) is rotated to generate an air flow, the air flow can be redirected by the side wall of the flow guide (33) to change the original flow direction, thereby concentrating out of the frame ( 3) The air outlet can reduce the generation of the turbulent flow field of the fan frame (3) and the surface of the vane (32), and reduce the noise generated by the turbulence. In addition, the design of the flow guiding members (33) can also prevent foreign matter from entering from the air outlet of the fan frame (3), and can protect the internal components of the fan frame (3). 〃 + Please refer to Figures 8 and 9. Another embodiment of the present invention is that the flow guiding member (33) includes a reinforcing portion (331) and a flow guiding portion (332), and the reinforcing portion (331) is coupled thereto. The curved surface (322) is connected from the vane (32), and the flow guiding portion (332) extends from the bottom of the reinforcing portion (331). The reinforcing portion (331) not only strengthens the overall strength of the flow guiding member (33), but also increases the sidewall area of the flow guiding member (33), thereby increasing the effect of rectification, and the air flow is by the flow guiding member ( 33) The side walls are guided to concentrate out of the fan frame (3). 6 M287387 The flow guide (33) can also be designed to extend from the upper curved surface (32丨) because the airflow will flow along the curved surface (321) of the vane (32). Please refer to FIG. 1 and FIG. 2, which shows that the flow guiding member (33) extends from the bottom of the curved surface (321) of the vane (32), and the rectification principle is the same as the foregoing, and Let me repeat. Of course, the flow guiding member (33) of this embodiment can also extend from the top of the upper curved surface (321). The focus of this creation is to extend at least one flow guide on the surface of the stationary vane. The side wall of the flow guide can effectively guide the flow of the airflow. Therefore, the shape and size of the flow guide are not particularly limited as in the case of I2 and As shown in Fig. 13, the flow guiding member (33) extends from the vane (32) and the upper surface (321) to increase the sidewall area for increasing the flow guiding effect; wherein ί = machine ^ (33) The top surface of the windward is an inclined surface along the flow direction of the airflow, which can reduce the loss of the raft. In order to respond to the fan blades of different sizes, sizes and shapes, and the wind and direction of the wind deflector, the size and shape of the deflector are also different, so that the description is only a preferred embodiment of the present invention. The examples are only for the scope of the patent application for the exclusive application of the Shenshe.
