[0002] A switch is a hardware device used in computer networks, primarily for connecting multiple network nodes such as computers, servers, and printers, and for efficiently forwarding and exchanging data frames. It improves network transmission efficiency and performance by identifying the destination address in the data frame and accurately transmitting data to the designated receiving device. Switches support various Ethernet standards and speeds and feature functions such as Virtual LANs (VLANs), Spanning Tree Protocol (STP), and Quality of Service (QoS) to enhance network flexibility, reliability, and security. Widely used in LANs, data centers, enterprise networks, and industrial automation, switches are a core component in building modern network infrastructure.

[0003] With the rapid development of data center operations, the demand for data center switches has increased dramatically. The switching capacity, number of ports, and speed of these devices are also constantly increasing, leading to a significant increase in power consumption. To ensure stable operation under high loads, heat dissipation has become a critical issue. As a core component for heat dissipation in data center switches, the performance of fans directly affects the reliability and lifespan of the equipment. Traditional fan installation and removal methods typically involve screw locking, which is complex and inefficient. Especially in high-density data center environments, this design increases maintenance difficulty and time costs. Utility Model Content

[0004] The main purpose of this invention is to provide a cooling fan and a switch, specifically a cooling fan for a switch that can be quickly disassembled and reassembled.

[0005] To achieve the above objectives, the present invention proposes a cooling fan for use in a switch, comprising:

[0006] The fan body has a housing on one side, the housing having a downward-opening receiving groove, and a rotating shaft is housed within the receiving groove; and

[0007] A rocker arm is rotatably mounted on the rotating shaft. The rocker arm includes a power arm and a resistance arm. The power arm is located outside the housing, and the resistance arm is located inside the receiving groove. The resistance arm has a snap-fit ​​part on the side facing away from the receiving groove, which is used to snap-fit ​​with the slot on the switch.

[0008] In one embodiment, the inner wall of the receiving groove is provided with a limiting member, which is located below the resistance arm.

[0009] In one embodiment, the cooling fan further includes a torsion spring sleeved on the rotating shaft. The torsion spring has a first abutting end and a second abutting end. The first abutting end is disposed on the limiting member, and the second abutting end abuts against the power arm.

[0010] In one embodiment, the latching portion includes at least one latching protrusion for engaging with a slot on the switch.

[0011] In one embodiment, the snap-fit ​​portion includes two snap-fit ​​protrusions, which are spaced apart along the extension direction of the rotating shaft.

[0012] In one embodiment, the outer casing has a handle on the side facing away from the fan body, the handle enclosing a receiving space, and the power arm is located in the receiving space.

[0013] In one embodiment, the cooling fan further includes a pressure plate, the pressure plate having a fixing groove, and the power arm being disposed in the fixing groove;

[0014] The pressure plate is located within the accommodating space.

[0015] In one embodiment, the pressure plate and the rocker are integrally formed.

[0016] In one embodiment, the cooling fan further includes a light guide, one end of which is exposed from the housing.

[0017] This utility model also proposes a switch, including the cooling fan described above.

[0018] This utility model proposes a cooling fan and a switch. The cooling fan mainly consists of a fan body and a rocker arm. One side of the fan body has a housing with a downward-facing receiving groove. A rotating shaft is installed within this groove. The rocker arm is rotatably mounted on the rotating shaft, and a snap-fit ​​part facing downwards is provided on the rocker arm. This snap-fit ​​part engages with a slot on the switch, thus fixing the cooling fan to the switch. When the cooling fan needs to be disassembled, the power arm of the rocker arm is manually pressed, causing it to rotate downwards around the axis and the resistance arm to rotate upwards around the axis.

[0032] With the rapid development of data center operations, the demand for data center switches has increased dramatically. The switching capacity, number of ports, and speed of these devices are also constantly increasing, leading to a significant increase in power consumption. To ensure stable operation under high loads, heat dissipation has become a critical issue. As a core component for heat dissipation in data center switches, the performance of fans directly affects the reliability and lifespan of the equipment. Traditional fan installation and removal methods typically involve screw locking, which is complex and inefficient. Especially in high-density data center environments, this design increases maintenance difficulty and time costs.

[0033] To address the aforementioned problems, this utility model proposes a cooling fan 100, aiming to provide a cooling fan 100 for a switch 200 that can be quickly installed and removed. Figures 1 to 6 This is a schematic diagram of one embodiment of the cooling fan 100 of this utility model.

[0034] Please refer to Figures 1 to 6This utility model proposes a cooling fan 100 for use in a switch 200. It includes a fan body 1 and a rocker arm 2. The fan body 1 has a housing 11 on one side. The housing 11 has a downward-facing receiving groove 1b. A rotating shaft 12 is provided in the receiving groove 1b. The rocker arm 2 is rotatably mounted on the rotating shaft 12. The rocker arm 2 includes a power arm 21 and a resistance arm 22. The power arm 21 is located outside the housing 11, and the resistance arm 22 is located in the receiving groove 1b. The side of the resistance arm 22 facing away from the receiving groove 1b has a snap-fit ​​part, which is used to snap-fit ​​with the slot 210 on the switch 200.

[0035] The present invention proposes a cooling fan 100 and a switch 200. The cooling fan 100 mainly comprises a fan body 1 and a rocker arm 2. The fan body 1 has a housing 11 on one side, and the housing 11 has a downward-facing receiving groove 1b. A rotating shaft 12 is set in the receiving groove 1b. The rocker arm 2 is rotatably mounted on the rotating shaft 12, and the rocker arm 2 has a downward-facing locking part. The locking part engages with the locking groove 210 on the switch 200, thereby fixing the cooling fan 100 to the switch 200. When it is necessary to disassemble the cooling fan 100, the power arm 21 of the rocker arm 2 is manually pressed, so that the power arm 21 rotates downward around the axis, and the resistance arm 22 rotates upward around the axis, thereby driving the locking part to move upward until it disengages from the locking groove 210 on the switch 200, thereby achieving disengagement and disassembling the cooling fan 100. The cooling fan 100 in this solution can be disassembled without the aid of external tools, which greatly facilitates the maintenance and repair of the equipment.

[0036] In the technical solution of this application, the rocker arm 2 is locked to the switch 200 by engaging with the slot 210 on the switch 200 through a snap-fit ​​part at one end of its resistance arm 22. The snap-fit ​​part includes two snap-fit ​​protrusions 23. For details, please refer to further details. Figure 3 and Figure 5 Two snap-fit ​​protrusions 23 engage with two slots 210 on the switch 200 to achieve positioning. This design provides more reliable fixing and positioning. The engagement of the two snap-fit ​​protrusions 23 with the slots 210 distributes force, preventing structural loosening or damage due to single-point stress, thus ensuring the stability of the cooling fan 100 under high load. Simultaneously, this dual-snap-fit ​​structure enhances locking reliability, reduces the risk of the fan accidentally falling off due to vibration or external force, and improves equipment safety and reliability. Furthermore, the dual-snap-fit ​​protrusion design facilitates installation and disassembly, further improving maintenance efficiency.

[0037] To prevent the locking protrusion 23 from moving further downwards and exceeding its predetermined position, making it difficult to disengage, a limiting member 5 is provided on the inner wall of the receiving groove 1b. For details, please refer to further documentation. Figure 3The limiting component 5 is located below the resistance arm 22. The limiting component 5 prevents the rocker arm 2 from rotating beyond its travel range and precisely controls the rotation angle of the rocker arm 2, preventing the locking protrusion 23 from exceeding its predetermined position due to excessive rotation, thus avoiding difficulty or damage to its disengagement from the slot 210 on the switch 200. By limiting the rotation range of the rocker arm 2, it ensures that the locking protrusion 23 can accurately engage or disengage from the slot 210, improving the reliability and consistency of the disassembly and assembly process. Simultaneously, the presence of the limiting component 5 enhances the stability of the entire structure, extends the service life of the cooling fan 100, and ensures the stability and safety of the equipment during frequent disassembly and assembly and long-term operation.

[0038] To achieve the reset of rocker arm 2, the locking protrusion 23 engages with the slot 210 of switch 200, preventing the locking protrusion 23 from disengaging from the slot 210 under external force. The cooling fan 100 also includes a torsion spring 3. For details, please refer to further documentation. Figure 3 A torsion spring 3 is sleeved on the rotating shaft 12. The torsion spring 3 has a first abutment end and a second abutment end. The first abutment end is located on the limiting member 5, and the second abutment end abuts against the power arm 21. This ensures that after the power arm 21 of the rocker arm 2 is manually pressed to disengage from the slot 210 of the switch 200, once the external force is released, the elastic force of the torsion spring 3 will automatically restore the rocker arm 2 to its initial position, allowing the locking protrusion 23 to re-engage tightly with the slot 210. This reset mechanism not only improves the installation and disassembly efficiency of the cooling fan 100, but also avoids the risk of accidental disengagement of the locking protrusion 23 from the slot 210 due to external force, enhancing the stability and reliability of the equipment. At the same time, the design of the torsion spring 3 simplifies the operation process, reduces maintenance difficulty, and reduces failures caused by improper human operation, further improving the practicality and durability of the cooling fan 100 in high-density deployment environments such as data centers.

[0039] To facilitate handling of the disassembled cooling fan 100, a handle 13 is provided on the side of the outer casing 11 facing away from the fan body 1. This allows staff to more easily control the direction and force of movement of the cooling fan 100, preventing slippage or damage caused by direct contact with the fan body 1. Especially in high-density equipment environments such as data centers, frequent maintenance and replacement operations require quick and safe handling of the cooling fan 100. Furthermore, the handle 13 encloses a receiving space where the power arm 21 is located. The cooling fan 100 also includes a pressure plate 4 with a fixing groove 4a, in which the power arm 21 is positioned. The pressure plate 4, located within the receiving space, securely restrains the power arm 21 within the space via the fixing groove 4a, further enhancing structural stability and ensuring that the power arm 21 will not shift or loosen due to external forces during use. This design not only improves the overall reliability of the cooling fan 100 but also simplifies the assembly process, reduces production costs, and enhances the product's aesthetics and user experience.

[0040] In the technical solution of this application, the pressure plate 4 is located within the accommodating space formed by the handle 13 and the outer casing 11, which further facilitates the disassembly operation by the staff. When it is necessary to disassemble the cooling fan 100, hold the handle 13 with one hand and press the pressure plate 4 downward with four fingers, so that the pressure plate 4 moves downward and drives the power arm 21 of the rocker 2 to rotate downward around the pivot 12. At this time, the resistance arm 22 of the rocker 2 also rotates upward around the pivot, thereby causing the locking protrusion 23 to disengage from the slot 210 on the switch 200. This series of actions is highly continuous and conforms to ergonomic design, which helps to achieve efficient disassembly and assembly.

[0041] In one embodiment of this application, the switch 200 has multiple cooling fans 100, each of which provides forced air cooling to different wiring boxes. A light guide 14 is also installed on the cooling fans 100 of the switch 200. Its main function is to evenly distribute and guide the light emitted by a light source (such as an LED strip), thereby achieving a more uniform lighting effect. Simultaneously, the light guide 14 can also serve as a status indicator, displaying the fan's operating status through different colors or flashing patterns of light, facilitating maintenance personnel to quickly determine whether the equipment is working properly, thereby improving the maintainability of the equipment and the user experience.

[0042] This utility model also proposes a switch 200, which includes a cooling fan 100. The specific structure of the cooling fan 100 is as described in the above embodiments. Since this switch 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0043] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
