New Description: [New Technology Field] This creation is about a "motor base with a wind guiding effect", especially a motor that allows fluid to flow along the base to eliminate the stagnant zone behind the base. Base structure 0 [Prior Art] A conventional fan motor includes a wheel and a frame. The fan frame is provided with a base for pivoting the fan wheel. One side of the fan frame defines an air inlet, and the other side defines An air outlet is facing the heating element, and at least the fixing element locks the fan wheel and the fan frame to the heat generating 7G piece J1. Since the base has a certain area and is formed into a plane body or a bluff body, it will form under the volume. - Low-pressure stagnation zone, when the airflow flows out from the air outlet, it will generate backflow, and will not flow to the area where the heating element is covered by the base, thereby greatly reducing the heat dissipation effect. Therefore, in order to solve the above-mentioned problems of the prior art, the Republic of China Public Publication No. 200622111 5 tiger "fan guide device" invention case, a fan guide device is provided at the wind side of the fan. The wind-flow device comprises a flow guiding cover and a guiding body disposed in the flow guiding cover. The flow guiding cover has a nozzle-like structure, and the inner surface of the inner surface is formed into a grasping curved surface structure, and one of the larger diameter ends is formed into the air inlet. One of the smaller diameters forms an air outlet, and the human air outlet of the shroud is provided with the aforementioned body in the region corresponding to the hub, the engraved conductor is a tapered structure, and the outer surface forms a streamlined structure. When the fan runs to generate a forced air flow, the airflow enters the fan-fed flow device M323762 through the air inlet, and the flow discharges the material to the convection. When the airflow flows out of the air outlet, a uniform high-speed jet is formed. However, there are problems in the use of the above technology. Due to the air outlet of the shroud and a certain area, the flow of the airflow is limited, and only a certain area of the radiator can be exchanged for heat, and no other area can be used. The flow of fluid from the fan to the fan guide will cause paving or chattering between the two, which will increase the noise, and the addition of the fan deflector will increase the cost and weight; therefore, it is necessary to know the secret. The shortcomings of technology to improve. The reason is that there are some shortcomings arising from the above-mentioned goods, and the creation of this case is 遂. θ ′ has been researching and innovating and improving the experience of the property industry for many years. Finally, it successfully developed this “Motor Base with Wind Guide Effect” case, which is an effective creation.

[Embodiment] Other advantages, objects, technical features and effects of the present invention can be understood by the following detailed description of the preferred embodiment of the present invention: Please refer to Figures 1 and 2 A frame u and a wheel 12 having two opposite sides m and 112 and a flow path 113 on the opposite side of the communication frame. A base 13 is disposed in the flow path 113. The base π includes An integral portion 131 and a shoulder portion 132 having a streamlined configuration (as shown in FIG. 3 ) extending along one side of the body portion 131 toward one side Π 1 of the fan frame 11 and as in the third As shown, a concave curved surface portion 133 that is tapered relative to the central axis 14 of the body portion 131 is formed, and the concave curved surface 133 forms a convex protrusion 134 at the center of the body portion 131. As shown in Fig. 2, the base 13 is connected to the inner wall of the frame u via a plurality of connecting portions 15 (indicated by three in the illustration of the present invention) so that the base 13 is in the flow path ι13 of the frame U. As shown in Fig. 4, the above-mentioned fan wheel η is pivotally disposed on the other side of the body 131, so that the fan wheel 12 is rotatably placed on the base 13; and the convex curved surface portion 133 is configured to protrude. The end 134 is more than 1 U on the side of the frame m, that is, the portion M of the concave and convex surface M323762 extends so that the convex end 134 is parallel or slightly shorter than the side 111 of the frame. As shown in the second and fourth figures, in the embodiment, the inner wall of the fan frame is further provided with a plurality of flow guiding portions 16 opposite to the base 13, the per-conducting flow (four) and the connecting end 161 and - free end 162, the connecting end 161 is coupled to the inner wall of the fan frame, the free end 162 is convex toward the base 13 and forms a space - the space - between the outer end of the free end 162 In addition, a second space 172 is formed between each of the guides. 1 If the 4th and 5th rides are set, the u u u group is disposed on the 赖 (4), so that the base 13 is opposite to the heat sink 18, the protruding end 134 faces the heat sink 18 corresponding to the lower area of the base 13 After the _, the body flows from the side 112 of the frame I to the radiator 18 of the other side, and the fluid passing through the first space (7) and the second six 172 is guided by the female base 13 of the flow guiding portion 16 Then, the shoulder portion is formed along the concave curved surface portion 133 to the convex end portion 134 corresponding to the heat sink 17 region, where the plum is present behind the 総13, and the heat dissipation domain that was previously covered by the base is solved. It is impossible to generate a sensitive change, and it is expected to increase the heat dissipation effect' and the fluid does not immediately flow to the fan frame u because of the needle, thereby enhancing the wind pressure 0. Further, the fluid flows along the concave curved surface portion 133, thereby reducing backflow generation. , enter 8 M323762 to reduce the noise generated by the fluid. In addition, the above description is performed by providing the flow guiding portion on the inner wall of the frame. However, the present invention is not limited thereto. If the arrangement of the flow guiding portion is omitted, the base can also generate a function of concentrating the fluid and generate the same as described above. The effect of the example.
