New description: [New technical field] This creation relates to a fan module, especially a fan module used in a server. [Prior Art] ^ With the rapid development of the electronics industry and the continuous advancement of computer technology, the server processing capability as a computer high-performance product has become stronger and stronger. The server structure has many similarities with the computer, such as CPU (central processing unit), memory, hard disk drive, various bus bars, etc., but it can provide various shared services (network, database, file). , printing, etc., and other high-performance applications, its high performance is mainly reflected in high-speed computing power, long-time reliable operation, strong external data throughput, etc., for the network backbone and information core. Once the server fails, the economic loss will be unpredictable. * To maintain uninterrupted server operation, the internal heat dissipation capability of the server is critical. When using high frequency CPU and disk array technology in the server, the heat dissipation problem becomes more important. When the fan runs for a long time, it is very easy to damage. In this case, the fan needs to be replaced in time to maintain the normal operation of the server. A servo fan fixing device includes a receiving frame for accommodating a fan and a fixing frame. The receiving frame is provided with at least one fastening portion, and the fan fixing device further comprises a pivoting fixing to the fixing frame. The upper bracket elastically connects the bracket to the fixing bracket, and the bracket forms a stopping portion corresponding to the fastening portion of the receiving bracket. When installing, first place the fan into the 6 M315854 rack, and then insert the fan and the rack combination into the holder horizontally. The structure of the fan fixing device is complicated, and when the server is running, the replacement fan component can easily contact other components of the server and affect the operation of the server. [New content] In view of the above, it is necessary to provide a server fan module with a simple structure and convenient installation. A fan module includes a fan fixing bracket and at least one air guiding unit mounted in the fixing bracket, the fixing bracket includes two parallel side B walls, and each side wall has at least one air guiding unit open at least one a venting opening, at least one fixing hole is formed on one side of each vent; the air guiding unit includes a fan and a first locking component that can be buckled to the fan, and the first locking component is fixed to the two sides of the first locking component The fixing holes of the two side walls are respectively provided with at least one elastic arm, and each elastic arm end is provided with a protrusion which can be buckled with the corresponding fixing hole. Compared with the prior art, the fan module of the present invention has a locking member fixed on the fan Φ, and the locking member is pulled upward to unlock the protruding block and the fixing hole, so that the fan can be disassembled, and the module has a simple structure and is used. Convenience. The fan module 20 includes a fixing bracket 30 and a plurality of air guiding units 40 mounted on the fixing bracket 30. The fixing bracket 30 includes an elongated bottom wall and is vertically bent upwardly along the two opposite sides of the bottom wall to form two side walls 31. Each side wall 31 is provided with a plurality of substantially circular vents 311 at equal intervals. Two fixing holes 313 are defined in each M315854 on each side of each vent 311. The bottom wall and the two side walls 31 surround the accommodating space for guiding the air guiding unit 40. Referring to FIG. 2, each air guiding unit 40 includes a fan 50 and a pair of locking members 60 that can be respectively hooked on both sides of the fan 50. A cylindrical wind wheel is arranged in the middle of each fan 50, and each end of each fan 50 is respectively provided with a fixing plate 51 of a square shape. Each of the fixing plates 51 is provided with four locking holes 511 near the four corners. The pair of locking members 60 have a symmetrical structure so as to be respectively fastened from the two sides of the fan 50. Each of the locking members 60 includes a square body portion 61 and a horizontal extension along the upper edge of the body portion 61. The edge 63 defines an operation opening 64 at the intersection of the main body portion 61 and the upper flange 63. The main body portion 61 is adjacent to the four corners and is convexly disposed with four lugs 65 on the side of the fan 50, and the distance between the outer sides of the two lugs 65 on the same height of the main body portion 61 is substantially equal to the two fixing plates of the fan 50. At a distance of 51, each lug 65 has a protrusion 651 corresponding to the locking hole 511 of the fan 50. The main body portion 61 includes two side edges 62. The upper and lower ends of each side edge 62 respectively extend from a pair of φ pairs to a resilient arm 67. Each elastic arm 67 and the main body portion 61 are separated by a section to allow the elastic arm 76 to be elastic. The distance between the outer sides of the two elastic arms 67 of the two sides 62 of the main body portion 61 is substantially equal to the distance between the two side walls 31 of the fixing bracket 30, and the end of each elastic arm 67 corresponds to the fixing bracket 30. The fixing hole 313 is convexly provided with a bump 671 having a semi-circular convex surface. Referring to Figure 3, the fixing bracket 30 is first fixed in the casing 10 during assembly. Then, a fan 50 and a pair of locking members 60 are respectively pressed, and the four lugs 65 of the pair of locking members 60 are respectively pressed inwardly to respectively engage the lugs 65 between the two fixing plates 51 of the M315854 and The protrusions 651 of each of the lugs 65 are respectively engaged in the corresponding locking holes 511 of the fan 50. At this time, the two locking members 60 are respectively buckled on both sides of the fan 50 to form a wind guiding unit. 40. Finally, the plurality of air guiding units 40 are respectively inserted into the accommodating spaces of the fixing brackets 30, so that the bumps 671 on both sides of each of the air guiding units 40 are respectively fastened to the fixing holes 313 corresponding to the side walls 31 of the fixing brackets 30. Inside. When one or more of the fans 50 are damaged, the fan 50 is pulled upwards, and the protrusion 671 of the air guiding unit 40 having the curved outer edge is pressed by the upper edge of the corresponding fixing hole 313 to make the protrusion 671 elastic. The arm 67 is elastically deformed inwardly. At this time, the protrusion 671 gradually disengages from the corresponding fixing hole 313, and the air guiding unit 40 is unlocked with the fixing bracket 30. Finally, the air guiding unit 40 is replaced or repaired to maintain normal operation of the server. In the preferred embodiment of the present invention, each of the air guiding units 40 can be provided with the locking member 60 only on the side of the fan 50, and the fan 50 is fixed in the fixing bracket 30, and the other side of the fan 50 can be correspondingly disposed. Easy to handle. In summary, this creation meets the requirements of the new patent and submits a patent application in accordance with the law.
