The heat source generated by J is increased. This is because if the heat source cannot be effectively discharged by the wind, the electronic device will not be able to process the electronic device. use. / In order to solve the problem of heat dissipation of the electronic device, the method frequently used is to install a heat-dissipating fan for the heating element of the electronic device (such as the device, the towel processor, the dragon circuit, etc.) to borrow The air flow phenomenon is achieved by the operation of the cooling fan, so that the heating element can maintain its operating efficiency within a certain temperature range. At the same time, in order to consider the cost of manufacturing heat dissipation and fine manufacturing, it is generally used as the cooling fan type of the bearing. The cooling fan of such a self-lubricating bearing, the operation of the fan rotor is supported by a rotating shaft pivotally disposed in the oil-impregnated bearing, and after the fan is assembled, a c-rotating end is fastened via the bottom of the sleeve. The retaining ring and the rib prevent the blade from coming out of the bearing due to the centrifugal force during operation. At the same time, in order to avoid the friction of the fan shaft seat and the C ^ buckle at the end of the rotating shaft, the fan must be kept empty at the upper and lower ends of the bearing, Λ, 丨, and the setting of the empty team causes the rotating shaft to lose a fixed position. Pivot. After a long period of operation, the rotating shaft will be too large due to the excessive force between the c-type buckle, so that the 5 M351277 c-type buckle is fatigued and worn, and it is easy to move up and down when loose. The problem of yaw and TM rafts results in a shorter heat dissipation 吏 life.

The secret of the noise generated by the base is ugly and the movement between the cover and the cover is explained by the above description of the creation and the following embodiments. M351277 is based on the principle of demonstration and entanglement, and provides further explanation of the patent of Lai. [Embodiment] The positioning structure of the fan disclosed in the present application is applicable to an electronic heat dissipation structure such as a display card chipset, a memory module, a mobile phone, a personal digital assistant, and a complementary digital camera. The above is only an example. Not limited to this. Please refer to "FIG. 1" for an exploded view of the first embodiment of the present invention. According to the positioning structure of the fan of the present invention, the base includes a base, a cover 20 and a fan 30. The base 1 has an accommodating space, and one end of the base is provided with a stop portion 12, a bearing 13 and a stator 14. The bearing is disposed above the shackle portion and has a shaft hole 131 for the portion of the damper portion 12 Exposed to the shaft hole 131, the die 14 has an opening 141 and is sleeved on the bearing by the opening ,4, and the bottom (four) is provided with a plurality of sets of buckles on the other side of the accommodating space „ a plurality of slots 16; the cover 2 has a limiting member 21, a connecting rib 22 and a truss 25. The position of the limiting member 21 corresponds to the stop of the base 1 and is connected by the connecting rib 22 The connecting rib 22 is connected to the frame 25, and the connecting rib 22 is arranged in a wavy shape. (10) The side edge of the body 20 is provided with a plurality of snap segments 23 and inserts 24, and the snap segments and the inserts 24 are separated from the wire 1G. The group of buckles 15 and 15; the 3〇 has 'one rotation (four) and - rotor 32, and the rotor 32 has - perforation % 31 = this wear (four) transmission buckle. Among them, the stator 14 and _23 like white know The technology is not a feature of this creation technique, so its detailed structural composition will not be described. Figure 2 and Figure 3 show the combination of the first embodiment of the creation and the M351277 profile: Fig. According to the first embodiment of the present invention, the end of the rotating shaft η of the fan 3q is sighed in the shaft hole 131 of the bearing 13, and is abutted against the finger n of the base (7), so that the rotor 32 of the fan 3G is at the bottom of the money. Above the stator 14, the fan 3 is rotatable within the accommodating space n of the base 10. Then, the buckles and the inserts 24, which are disposed on the edge of the cover body, are correspondingly fastened to the group of the base 10! 5 and the fittings == the groove 16 of the base 10, so that the cover body 2Q is stably shackled to the base 10, at this time: the limit member 21 on the basin 2 () is in contact with the fan 30 relative to the fan 30 At the other end of the Department 12. The end of the rotating shaft 31 is abutted against the stopping portion of the base 10, and the other end is abutted against the limiting member 21 of the cover 20, so that the fan 3 is clamped to the base 10 and the cover in the receiving space. Stable rotation between the bodies 2〇 does not cause the fan % to move in the same axial direction as the rotating shaft 31 between the base 10 and the cover 20 as the fan rotates. Meanwhile, if the positioning structure of the fan of the present embodiment is reversed, the horizontal flip is taken as an example, as shown in FIG. 4, since the fan 3G is sandwiched by the rotary shaft 31. Between the base and the cover body 20, therefore, the fan 3〇曰 can maintain the phase between the cover body 20 and the base 1〇 according to the different angles of the laying, thereby effectively avoiding the fan 3 due to the flip angle. The difference is caused by the axial movement between the cover 2 〇 and the base 10. In addition, please refer to the "Fig. 1" and "Fig. 2" again, the connecting rib 22 of the cover body is arranged in a wave shape, and is connected between the limiting member 21 and the frame, when the fan 30 Rotating and driving the surrounding air to generate a vertical flow direction from the base 1 into the accommodating space 11 and discharging from the cover 2 于 outside the accommodating space n, when the air is discharged from the cover 20, due to the undulation The linear guide 9 M351277 of the connecting rib 22 is introduced so that the discharged airflow is not provided between the fan 3〇 and the cover 20 or in the county where the cover 20 is disturbed by the outer surface of the base 1 (four), and provides a smooth air force. The sub-, in turn, effectively reduces the formation of spoiler and wind-cut noise. Please refer to the "Fiveth Image" and "Pixel Figure" for the second embodiment of the creation. The second embodiment of the present invention is structurally different from the first embodiment, and only the differences between the two embodiments will be described below. According to the positioning structure of the wind 4 of the present invention, the fan 3 has a holding portion 322, a two groove cut, a rotation _ 31 and a rotor 32, and the top portion 32:: On the side, the end of the rotating shaft 31 is disposed in the groove I: = 30. The hunting portion 322 is supported by the top portion 322 against the limit of the cover body 31 323 i3 and abuts against the stop portion 12 of the base 1 (). , with the cover 20 door (four) 7 fan 30 is clamped between the base 1 〇 U0, and avoid the fan 3 squatting on the base (four) reciprocating movement. For example, as shown in "Fig. 7", one of the third embodiment of the creation is made third, and the second embodiment is structurally ... L. The differences between the creations are explained. According to the present creation / I, only the two real positioning structures 'where the accommodation space „ is set; ^ the disclosed fan and the limit member 21 of the product body 20 has a mouthpiece of the peach set in the limit piece paste In the case of the fan 30, when the bump 211 is assembled to the base 10, the cover body 2 〇 幻 幻 盍 盍 盍 〇 〇 〇 〇 风扇 风扇 322 322 322 322 322 322 322 322 322 The wind* is lost between the bottom 10 M351277 seat 10 and the body 20. Wherein, in the first embodiment and the second embodiment, when the fan 3 turns, the ambient air is generated to generate a flow from the base into the accommodating space η, and then discharged from the body 20 in the vertical direction of the airflow outside the accommodating space π, according to In the third embodiment of the present invention, the flow direction of the airflow when the fan 30 rotates is from the cover body 20 into the accommodating space, and is discharged from the flow port to the horizontal flow direction outside the accommodating space 11. Therefore, The positioning structure of the fan disclosed in the creation can be applied to both the vertical flow direction of the airflow and the fan type flowing in the horizontal direction. The positioning structure of the fan disclosed in the present application is based on the rotation axis of the fan, or _ and the combination of the weighing part, so that the two ends of the fan are divided into the stop part of the base and the limit piece against the cover body, so that the fan is clamped to the position of the base and the cover body, no _ help C The setting of the type buckle can prevent the fan from generating a reciprocating displacement between the base and the cover body and rotating the shaft, and the friction between the rotating shaft and the bearing is low, so that the rotation is stabilized by the bearing. And solve The problem of noise generated when the fan rotates. The corrugated material rib provided on the stomach at the same time provides the first-class Yang's mechanical reduction when the fan is running, which can effectively call the low airflow disturbance and help the noise. The embodiments of the present invention are disclosed as described above, but are not intended to limit the ingenuity of any of the skilled artisans, without departing from the spirit and scope of the present invention, the shape, structure, characteristics and spirit of the application for the application of the model.
