Description

Technical Field

[0001] This utility model belongs to the field of cooling fan technology, and in particular relates to an adjustable-angle cooling fan. Background Technology

[0002] Cooling fans, as a key heat dissipation device, are widely used in various electronic devices, computers and electrical products. Their core function is to effectively dissipate heat and cool down, ensuring that these devices can operate stably within a suitable temperature range.

[0003] When the cooling fan starts, the rotation of the fan blades drives the flow of surrounding air, creating a continuous airflow. This airflow not only accelerates the heat exchange between the heat source and the surrounding air, but also carries heat from inside the equipment to the external environment through convection, achieving effective heat dissipation, reducing the operating temperature of the equipment, and extending its service life.

[0004] Currently, conventional cooling fans and cooling modules are fixed together with screws, achieving efficient heat dissipation through a combination. However, after prolonged operation, dust accumulates on the fan blades. Since the cooling fan and cooling module are fixed with screws, cleaning the cooling fan requires removing each screw individually, which is a complex and time-consuming process. Furthermore, repeated removal of the screws can cause stripping between the screws and the cooling module, resulting in gaps between them and preventing a tight fit between the cooling fan and the cooling module.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0031] In one embodiment of this utility model, such as Figures 1-5 As shown, an adjustable-angle cooling fan is provided, including a fan body 10 and a water-cooling assembly 20. A rotating block 11 is provided at the top of the fan body 10, and a connecting portion 111 extending outwards is provided on one side of the rotating block 11. The water-cooling assembly 20 is disposed on one side of the fan body 10, and a rotating seat 21 is provided at the top of the water-cooling assembly 20. The connecting portion 111 is disposed within the rotating seat 21, and a rotating shaft 211 is provided between the connecting portion 111 and the rotating seat 21. One end of the rotating shaft 211 is rotatably connected to the rotating seat 21 and connected to the connecting portion 111. The other end of the rotating shaft 211 passes through one side of the rotating seat 21 and is connected to a rotating component 30 for controlling the rotation of the rotating shaft 211.

[0032] A fixing component 40 for fixing the fan body 10 and the water-cooling assembly 20 is also provided between the fan body 10 and the water-cooling assembly 20. The fixing component 40 includes a fixing base 41 and a fixing block 42. The fixing base 41 is located on the outside of the fan body 10. The fixing block 42 is movably located on the outside of the water-cooling assembly 20, and the fixing block 42 can enter or leave the fixing base 41.

[0033] By setting up a rotating connection between the fixed component 40, the rotating part 30, and the rotating block 11 and the rotating seat 21, the fan body 10 can be quickly released from the water cooling component 20 by quickly disassembling the fixed seat 41 and the fixed block 42 without having to unscrew each screw. Then, by rotating the rotating part 30, the fan body 10 can be rotated upward along the fan-shaped arc, making it easy for the user to clean all the dust inside the fan body 10. Since the fan body 10 rotates upward along the fan-shaped arc, it ensures that the cleaned dust will not fall directly into the water cooling component 20, thus avoiding the dust contamination problem of the water cooling component 20.

[0034] Preferably, the rotating component 30 includes a mounting base 31 and a rotation damper 32. The rotation damper 32 is sleeved on the outside of the rotating shaft 211 and located between the rotating shaft 211 and the rotating base 21. The mounting base 31 is located on the outside of the rotating base 21. A first gear 33a and a second gear 33b are provided inside the mounting base 31. The other end of the rotating shaft 211 passes through the mounting base 31 and is fixedly connected to the center of the first gear 33a. The second gear 33b is meshed with one side of the first gear 33a, and a control lever 34 for controlling the rotation of the second gear 33b is provided on the second gear 33b. By setting the rotation damper 32, the control lever 34 is rotated, and the rotation damper 32 provides appropriate resistance, allowing the fan body 10 to stop at any angle, which is convenient for the user to adjust as needed for dust cleaning of the fan body 10. In addition, by using gear transmission between the first gear 33a and the second gear 33b, the rotation is more precise, reducing errors caused by manual rotation, and further improving the stability and durability of the cooling fan.

[0035] Specifically, the control lever 34 includes a connecting shaft 341 and a connecting cap 342. One end of the connecting shaft 341 is fixed to the center of the second gear 33b, and the other end passes through the mounting base 31 and extends to the outside of the mounting base 31, and is connected to an external toothed portion 341a, which is connected to the connecting cap 342. The connecting cap 342 has an internal toothed portion 342a that meshes with the external toothed portion 341a. The connecting cap 342 has a cavity 342b inside, the inner diameter of which is larger than the outer diameter of the external toothed portion 341a. The external toothed portion 341a can enter the internal toothed portion 342a and mesh with it or disengage from the internal toothed portion 342a to move into the cavity 342b, so that the connecting cap 342 can engage or disengage from the connecting shaft 341.

[0036] The outer toothed part 341a is provided with a first magnet 341b at its top end, and the inner wall of the connecting cap 342 is provided with a second magnet 342c that is attracted to the first magnet 341b at its top end.

[0037] By setting an external toothed part 341a and an internal toothed part 342a, when the control lever 34 does not need to adjust the fan body 10, the connecting cap 342 is pressed towards the connecting shaft 341, causing the external toothed part 341a and the internal toothed part 342a to disengage from each other. That is, the external toothed part 341a moves into the cavity 342b, preventing accidental rotation of the connecting cap 342 from causing the fan body 10 to rotate and affecting its tilt angle. At the same time, by setting a first magnet 341b and a second magnet 342c, the first magnet 341b and the second magnet 342c attract each other, further ensuring that the fan body 10 will not rotate accidentally when the control lever 34 does not need to adjust the fan body 10, thus improving the stability of the fan body 10.

[0038] Furthermore, a connecting hole is provided in the connecting part 111. The rotating shaft 211 is located in the connecting hole and is tightly connected to the connecting hole. The tight connection between the connecting hole and the rotating shaft 211 ensures the stability and reliability of the fan body 10 during rotation and reduces loosening caused by rotation.

[0039] Preferably, a movable seat 43 is provided between the fixed block 42 and the water-cooling assembly 20. The movable seat 43 is provided with a sliding groove for the fixed block 42 to slide. By setting the movable seat 43 and the sliding groove, the fixed block 42 can easily slide on the water-cooling assembly 20, thereby realizing quick fixing and unlocking between the fan body 10 and the water-cooling assembly 20, simplifying the operation steps.

[0040] Furthermore, the mounting base 41 is provided with a snap-fit ​​hole for one end of the mounting block 42 to enter or disengage. The mounting base 41 has an upwardly protruding first limiting part 411 on the side away from the mounting block 42. By providing the first limiting part 411, the mounting block 42 is prevented from falling off or loosening during the movement of the mounting base 41, thereby ensuring a tight fit and stability between the cooling fan and the cooling module.

[0041] Furthermore, the fixing block 42 has an upwardly protruding second limiting part 421 on the side away from the fixing base 41. By providing the second limiting part 421, the fixing block 42 is limited.

[0042] Preferably, the fan body 10 is provided with a first filter 12, and the first filter 12 is connected to the fan body 10 by screws. By providing the first filter 12, it helps to prevent dust and impurities in the air from entering the fan body 10, thereby extending the service life of the cooling fan.

[0043] Preferably, the water-cooling assembly 20 includes a water-cooling shell. The water-cooling shell contains water-cooling pipes 24 and multiple sets of equally spaced heat dissipation fins 23, with the water-cooling pipes 24 passing through each set of heat dissipation fins 23. A second filter 22 is provided on the side of the water-cooling shell away from the fan body 10. The water-cooling pipes 24 and multiple sets of heat dissipation fins 23 within the water-cooling shell can quickly remove heat and dissipate it into the air, thereby ensuring the stable operation of the cooling fan in high-temperature environments and improving the performance of the cooling fan.

[0044] Furthermore, the water-cooling pipe 24 includes multiple sets of equally spaced U-shaped pipes 241, with the ends of the multiple sets of U-shaped pipes 241 connected together. The first set of water-cooling pipes 24 is connected to an inlet head 242 at its first end. The last set of water-cooling pipes 24 is connected to an outlet head 243 at its last end. By setting up the U-shaped pipes 241, inlet head 242, and outlet head 243, the circulation and replacement of coolant are facilitated, thereby ensuring the continuous and efficient operation of the water-cooling assembly 20, improving the heat dissipation efficiency of the cooling fan, and also providing it with a longer service life and better maintainability.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
