[0002] A cooling fan consists of fan blades, bearings, a motor, a circuit board, and a housing. To improve the cooling effect of a cooling fan, heat dissipation fins are usually added to it.

[0003] Existing cooling fans are generally detachably mounted on the side wall of the heat sink fins using clips. After the cooling fan is installed, its direction cannot be adjusted on the heat sink fins. The clips need to be removed to adjust the position of the cooling fan, which greatly reduces the practicality of the equipment. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] refer to Figure 1-3As shown, the present invention provides a cooling fan with heat dissipation fins, comprising: a fan body 13 and a heat dissipation fin body 6. A hollow mounting base 4 is detachably provided on the heat dissipation fin body 6. A rotating pipe clamp 3 is rotatably provided on the mounting base 4. A 45-degree bend 2 is provided between the rotating pipe clamp 3 and the fan body 13. The rotating pipe clamp 3 allows the fan body 13 to be adjusted in multiple directions on the mounting base 4 based on rotation.

[0021] Combination Figure 2 As shown, a rotating block 14 is provided on the outer wall of the top of the mounting base 4, and a rotating groove 8 is provided on the inner wall of the rotating pipe clamp 3 to accommodate the rotation of the rotating block 14.

[0022] Combination Figure 2 As shown, the mounting base 4 includes an integral hollow structure connecting pipe and a mounting flange. A connecting piece is provided between the mounting flange and the heat dissipation fins for fixed connection. The rotating block 14 is located on the outside of the hollow pipe at the end away from the mounting flange.

[0023] As described above, using the fan body 13, heat dissipation fin body 6, mounting base 4, rotating pipe clamp 3, and 45-degree bend 2 provided by this utility model, the heat dissipation fin body 6 is installed in the predetermined installation position, the mounting flange on the mounting base 4 is detachably installed on the heat dissipation fins through the connector, and the 45-degree bend 2 is rotatably installed on the connecting pipe through the mounting pipe clamp. When the rotating pipe clamp 3 rotates on the connecting pipe, it can drive the fan body 13 on the 45-degree bend 2 to adjust the installation direction.

[0024] Furthermore, to facilitate the detachable mounting of the fan body 13 onto the 45-degree bend 2, refer to... Figure 1-2 As shown, the end of the 45-degree bend 2 is also provided with a mounting frame 1. The inner wall of the mounting frame 1 is provided with a mounting slot 9 to accommodate the fan body 13. Each of the four corners of the fan body 13 is provided with a fixing screw 15 that is screwed into the mounting slot 9. The mounting frame 1 provides a mounting position for the fan body 13 on the 45-degree bend 2. The fan body 13 can be detachably mounted on the mounting frame 1 through the mounting slot 9 and the four fixing screws 15.

[0025] Furthermore, to facilitate the detachable mounting of mounting bracket 4 onto the heat sink fins, refer to... Figure 1-2 As shown, the connector includes four connecting bolts 5. Each of the four corners of the mounting flange and the four corners of the heat sink fins has a coaxial through hole 11 and a first threaded hole 10. One end of each connecting bolt 5 is inserted into the coaxial through hole 11 and the first threaded hole 10. The mounting flange is placed on the heat sink fins, aligning the through holes 11 at the four corners of the mounting flange with the four first threaded holes 10 on the heat sink fins. Then, the four connecting bolts 5 are installed in the coaxial through holes 11 and the first threaded holes 10, thereby detachably mounting the connecting pipe onto the heat sink fins.

[0026] In this utility model, combined with Figure 1-3 As shown, the rotating clamp 3 of this embodiment is also provided with an adjusting bolt 7 for rotation limit on the outside. The outer wall of the rotating clamp 3 is provided with a second threaded hole 12 that communicates with the rotating groove 8. One end of the adjusting bolt 7 is threaded through and screwed into the second threaded hole 12, and the other end of the adjusting bolt 7 abuts against the rotating block 14.

[0027] As described above, when using the rotating adjusting bolt 7 provided by this utility model, the adjusting bolt 7 reciprocates in the second threaded hole 12. When the adjusting bolt 7 moves outward in the second threaded hole 12, it disengages from the rotating block 14. At this time, the rotating clamp 3 can be rotated and adjusted on the mounting base 4. When the adjusting bolt 7 moves inward in the second threaded hole 12, one end of the adjusting bolt 7 abuts against the rotating block 14. At this time, the rotating clamp 3 cannot rotate on the mounting base 4, thereby preventing the rotating clamp 3 from being rotated and adjusted on the mounting base 4.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
