Description of the Invention: [Technical Field] The present invention relates to a fan device, and more particularly to a fan device suitable for heat dissipation of a heat-generating electronic component. [Prior Art] [0002] With the rapid development of the computer industry, the heat dissipation problem derived from the pursuit of high speed and multi-function of the CPU is becoming more and more serious. Therefore, heat must be dissipated in a timely and effective manner, otherwise it will greatly affect The working performance of electronic components. [0003] A blower is commonly used inside a computer mainframe and a server to dissipate heat from a heating electronic component such as a CPU. Normally, the blower is directly fixed to the casing of the computer mainframe or the servo, and the air outlet of the blower is aligned with the heating electronic component. When the blower is running, an air flow is generated, and the airflow is discharged through the air outlet, and the heat is blown to the heat-generating electronic component. Electronic components dissipate heat. [0004] However, the replacement of the motherboard during system upgrade may cause the position of the heat-generating electronic components to change. The blower is directly fixed to the casing, and the position of the air outlet is fixed. Accordingly, the direction of the air outlet is also fixed, and cannot be adjusted according to the position of the heat-generating electronic component. Poor, the replacement of the blower at the same time as the replacement of the motherboard, resulting in increased costs and waste of resources. SUMMARY OF THE INVENTION [0005] In view of the above, it is necessary to provide a fan device that can easily adjust the direction of the wind as needed.

The chute 221 extends from one end of the long rib 222 to the other end and communicates with the outside at both ends of the long rib 222. The cross section of the chute 221 has an inverted "T" shape, that is, the width of the bottom of the chute 221 is larger than the width of the top portion thereof. A locking hole 223 is defined in each of the two ends of each of the long ribs 222. A screw (not shown) can be engaged with the screw hole on the casing through the locking hole 223 to fix the base 22 to the casing. [0011] Referring to FIG. 3 together, the guide ring 24 has an annular shape and is disposed above the base 22. The center of the guide ring 24 defines an annular channel 242 that is concentric with the guide ring 24. The section of the channel 242 also has an inverted "T" shape, i.e., the bottom of the channel 242 is wider than the top, forming a structure that is narrower and wider. A gap 244 is formed in the rail ring 24 through which the fixing member 26 can enter the channel 242 of the rail ring 24. [0012] The bottom of the guide ring 24 is provided with four fasteners 25. These fasteners 25 have the same shape and structure. Each fastener 25 includes a cylindrical connecting portion 252 and a fastening portion 254 connected to the bottom end of the connecting portion 252. The engaging portion 2 5 4 has a disk shape. The outer diameter of the fastening portion 254 is larger than the outer diameter of the connecting portion 252. The outer diameter of the engaging portion 2 54 is equivalent to the bottom width of the sliding groove 221 of the base 22, and the outer diameter of the connecting portion 252 is equivalent to the width of the top portion of the sliding groove 221. 2 and FIG. 4, the two fixing members 26 have the same shape and structure. Each fixing member 26 includes a columnar body portion 262, a thin rod portion 264 formed at the bottom of the body portion 262, and A joint portion 266 is attached to the bottom of the thin rod portion 264. The outer diameter of the main body portion 262 is the largest, and the thin portion 264 between the main body portion 262 and the joint portion 266 is the smallest. The outer diameter of the joint portion 266 is equivalent to the width of the bottom portion of the channel 242 of the guide rail 24, and the outer diameter of the thin rod portion 264 of the fixing member 26 is less than or equal to the 098131844. Form No. A0101 Page 6 / Total 18 pages 0982054651-0 201111645 The width of the top of the channel 242. [0015] 组装 [0015] When assembling, the four fasteners 25 of the guide ring 24 are firstly inserted into the sliding slot 221 from one end of a long rib 222 of the base 22, and the fastening of each fastener 25 is performed. The portion 254 is received in the bottom portion of the corresponding slot 221, and the connecting portion 252 is fixedly coupled to the bottom of the rail ring 24 to fasten the rail ring 24 to the base 22. The fastener 25 can drive the rail ring 24 to move horizontally along the extending direction of the chute 221 . The two fasteners 26 are then snapped into the annular channel 242 of the rail ring 24 from the notch 244 of the rail ring 24. The engaging portion 266 of each fixing member 26 is received in the bottom portion of the annular channel 242 having a larger width, and the thin rod portion 264 is received in the top of the annular channel 242 having a smaller width, so that the two fixing members 26 and The rail ring 24 is coupled and prevents the retaining member 26 from disengaging upwardly from the rail ring 24. The ' Finally, the two fixing members 26 are respectively aligned with the positions of the fixing holes 180 of the two lugs 18 of the air blower 10, and the body portion 262 of the fixing member 26 is passed through the lug 18 of the air blower 10 from the bottom to the top. Thus, the blower 1 is fixed to the guide ring 24, and the blower 10 is fixed to the casing of the system. 6 Since the fixing member 26 is circumferentially movable along the annular groove 242 of the guide ring 24, The blower 10 rotates along the axis of the guide ring 24 as the fixed member 26 moves circumferentially along the guide ring 24, and the position of the air outlet 160 is rotated correspondingly while the blower is rotating. Adjust the direction of the air blower 1 出. As shown in FIG. 5, the blower 10 of the fan unit 1 can be rotated along its axis. Thus, when the position of the heat-generating electronic component on the main board of the system changes, the direction of the air blower 10 can be easily adjusted to cause the heat to be aligned. The electronic components, so that the fan device 1 〇〇 has better compatibility with 098131844 Form No. A0101 Page 7 / Total 18 Page 0982054651-0 201111645. In addition, since the fastener 25 can drive the guide ring 24 to move horizontally along the extending direction of the sliding slot 221 of the base 2 2 , the air blower 10 can move horizontally along the extending direction of the sliding slot 221 along with the guide ring 24 . Thereby, the position of the blower 10 can be adjusted to make it easier to adjust the relative position with the heat-generating electronic components for better compatibility. [0016] FIG. 6 shows a second embodiment of the fan device of the present invention. The fan device 200 is different from the first embodiment in that the base 22 is provided with two guide rings 24 and are respectively disposed on the two. Two blowers 10 on the rail ring 24. The structure of the guide ring 24 and the blower 10 is the same as that of the guide ring 24 and the blower 10 in the first embodiment, respectively. Since the guide ring 24 is attached to the base 22 by means of a snap, the base is The plurality of rail rings 24 and the blower 10 can be expanded on the seat 22 as needed, or one or a plurality of rail rings 24 and the blower 10 can be detached as needed, so that the fan unit of the present invention has excellent expandability. [0017] In summary, the present invention complies with the requirements of the invention patent, and submits a patent application according to law.
