New description: [New technical field] This creation is about a cooling fan, especially a centrifugal fan. [Prior Art] With the development of technology, the development of electronic products and electronic components has become more and more important, and the problem of heat dissipation is particularly important. The heat dissipation problem not only affects the internals of electronic products or electronic components. The operation will affect the service life of electronic products or electronic components. Therefore, current electronic products or electronic components use a fan to remove the heat generated by them. As shown in the first figure, it is a three-dimensional exploded view of a conventional centrifugal fan. As shown in the figure, the centrifugal fan is composed of a socket 1a, a cover 2a, an impeller group 30a, and a plurality of The bracket 4 comprises a bottom plate na, a surrounding plate 12a extending from the bottom plate 11a, and a plurality of screw holes 13&; the cover plate 20a has a plurality of fixing holes 21a, the fixing holes 21a are disposed corresponding to the screw holes 13a, and the fixing holes 21 & are inserted into the fixing holes 21 & to lock the cover plate 20a to the socket 10a; the impeller group 3〇 & then set = on the bottom plate 11a. However, in the design of the centrifugal fan described above, there is still a problem in that the combination of the cover plate 20a and the socket 10a is locked by the screw inspection 40a, so that it is locked. In the process, there will be time-consuming and laborious problems, and the cumbersome and inconvenient locking will be caused. In addition, the 5 M339902 screw-in 4Ga δ will be added, which will also increase the material cost of the centrifugal fan production; 'When the centrifugal fan is in use, the vibration caused by the operation of the impeller 30a makes it easy for the bolts to be detached from the screw holes 13a to cause the cover plate 2a to vibrate and generate noise. . In view of this, the creator has made great efforts to improve and solve the above-mentioned shortcomings, and has devoted himself to the study and the use of academics, and finally proposed a design that is reasonable in design and effective in improving the above-mentioned defects. [New content] In view of this, one of the purposes of the present invention is to provide a heat dissipating fan which is fastened to the socket by heating and pressing the studs on the socket. It is fast, simple and saves group time on the group exhibition. Another object of the present invention is to provide a heat dissipating fan which has the advantages of material cost saving and shock absorbing effect by the studs made of plastic material. Another object of the present invention is to provide a cooling fan that breaks the stud by heating and pressing, so that the cover is tightly coupled to the socket and avoids the joint between the cover and the socket. The gap is such that when the impeller of the impeller group is operated, the cover plate vibrates and generates noise, so the creation has a low-pitched sound effect. Therefore, the present invention provides a cooling fan, which is composed of a socket, a plate, and an impeller group; the socket includes a bottom plate, a surrounding plate extending from the bottom plate, and a molding on the surrounding plate. a plurality of studs, the cover has a plurality of fixing holes, and the fixing holes are correspondingly sleeved and 6 • M339902 pressurizes the studs to deform them, so that the core diameters are larger than The aperture of the hole is defined to be coupled to the socket, and an accommodating area is formed between the cover and the socket; the group is received in the accommodating area. [Embodiment] -u under the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ One " Please refer to the second figure, the creation of the cooling fan is specific to the fan; and the creation of the cooling fan is composed of - bearing (four) one and an impeller group 30. 1 The holder ίο includes a bottom plate n, a panel 12 extending from the bottom plate, and a plurality of studs 13 formed on the panel 12, wherein the shape of the 12 is c-shaped. The ice _ τ ^ 卜, the socket 1 〇 is further provided with a cylinder 14 extending from the outside of the siding 12, and the cylindrical body 14 is formed on the cylinder 14 , the cylinder The body 14 can be an approximately circular hollow cylinder, and the socket 10 can be made of a plastic material, and is formed by a force of forming, wherein the plastic can be The plastic or thermosetting plastic is taught, and the seat can also be made of a material, and is integrally formed by extrusion molding. The cover plate 20 is provided with an air inlet 24, a plurality of fixing holes and a lug 2^3, and one of the fixing lugs 23t is fixed (four), and the fixing holes 21 are correspondingly convex. The column 13 is sleeved and the columns are twisted to be deformed, and the diameters of the convex (four) deformations are respectively larger than the diameters of the 7·M33 9902 fixing holes 2i to cover the cover 2 The cover plate 20 can be a metal cover plate 2, and the fixing hole 21 can be a circular hole corresponding to the outer shape of the protrusion 13; An accommodating area 4 is formed between the cover plate 20 and the socket 1 , and a blowing port 25 is disposed on the weeping side of the accommodating area. The impeller group 30 is housed in the accommodating area, and is disposed in the air inlet 24, and the air σ25 is connected to the accommodating unit (4) and located in the yoke group. One side, wherein the impeller group 3 is. The utility model comprises an impeller Μ and a driver 32 connected to the impeller 31. The driver 32 is used for driving the impeller 31 to rotate; however, the structure of the driver 32 is composed of a certain substructure and a mouthpiece at 5 hai. The structure of one of the rotor structures on the structure of the rafter is a constructor of the prior art, and therefore will not be described in detail herein. When assembling the present creation, as shown in the third to sixth figures, firstly, the name of the cover plate 20 is correspondingly positioned in the protrusions a of the socket 1,, and the convexities are made. The top surface of the column 13 is exposed and protrudes from the top surface of the cover plate 2, and the material of the socket 10 is made of plastic, and can be processed by means of, for example, ultrasonic waves to thermally melt the top of the column 13 And pressing, so that the outer diameter of the top surface of the stud 13 is larger than the diameter of the fixing hole 21, and if the material of the socket 1 is aluminum, the post can be processed by, for example, stamping. 13 The top stamping damage is such that the outer diameter of the top surface of the stud 13 is also larger than the diameter of the fixing hole 俾, and the cover plate 2 is quickly and tightly coupled to the socket 1 , to cost the creator Therefore, the present invention is quick and simple in assembly and saves assembly time, and is different from the lack of the bolt-on method in the prior art. M339902 In addition, during the use of the present invention, a gap can be avoided between the cover plate 2 and the coaming plate 12, so that when the impeller group 3 is operated, the cover plate 20 is generated. Vibration and noise generation. In addition, the studs 13 are made of plastic materials, so they are low in cost and have the effect of shock absorption. Therefore, the use of the present invention has low noise, material cost and shock absorption. , low ° voice, already available
