Description

Technical Field

[0001] This invention relates to the field of server fans, specifically a foldable server fan structure. Background Technology

[0002] With the rapid development of information technology, the computing power and integration of servers are constantly improving, and the heat generated during operation is also increasing. An efficient heat dissipation system has become the key to ensuring the stable operation of servers.

[0003] Currently, servers typically use fans for cooling. However, traditional server fan structures have many problems. On the one hand, traditional fans have fixed structures and take up a lot of space when not in use or when they need to be stored, which is not conducive to the movement and storage of servers and the rational planning of data center space. On the other hand, their cooling methods are limited and cannot meet the needs of servers of different sizes and cooling requirements. When faced with high-heat components or large servers, the cooling effect is poor.

[0004] In addition, the installation position of traditional fans is relatively fixed, making it difficult to adjust flexibly according to the internal structure of the server and failing to fully utilize the heat dissipation efficiency. Moreover, the fans are prone to drawing in dust during operation, and existing dust prevention measures are often inadequate, causing dust to enter the fan and affecting its lifespan and heat dissipation performance. Therefore, there is an urgent need to develop a new type of server fan structure to address the shortcomings of traditional fans in terms of space utilization, heat dissipation flexibility, installation adaptability, and component protection. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a foldable server fan structure.

[0006] The technical solution adopted by this invention to solve its technical problem is: a foldable server fan structure, including two first fan housings and a first fan, the first fan being rotatably connected inside the first fan housing, a mounting frame being fixed to the outer wall of the first fan housing, a strip-shaped groove being hollow inside the mounting frame, a support member being slidably connected inside the strip-shaped groove, a fixing member being threaded to the top of the support member, a connecting shaft being rotatably connected to the side of the support member away from the mounting frame, an auxiliary heat dissipation component being fixed to the bottom end of the connecting shaft, a limiting partition being fixed inside the hinge assembly, a light rod being slidably connected inside the limiting partition, a reset component being fixed to one side wall of the limiting partition, a first limiting plate being fixed to the outer wall of the light rod, and a second limiting plate and a knob being fixed to both ends of the light rod, respectively.

[0007] Furthermore, a screw is fixed to one side of the top of the support member, the screw passes through the strip groove of the mounting frame and is threadedly connected to the fixing member, and a rotating shaft is fixed to the bottom of the connecting shaft.

[0008] Furthermore, the auxiliary heat dissipation component includes a second fan housing, a second fan is rotatably connected inside the second fan housing, a circular magnet is fixed at the connection between the second fan housing and the first fan housing, and the top of the second fan housing is connected to a rotating shaft.

[0009] Furthermore, a hinge is fixed at the connection between the two mounting frames, and a bar magnet is fixed on the front surface of the mounting frame away from the hinge.

[0010] Furthermore, the reset assembly includes a spring, which is fixed to one side wall of the limiting partition. A spring pressure plate is fixed to the end of the spring away from the limiting partition, and the interior of the spring pressure plate is connected to the light rod.

[0011] Furthermore, the connecting shaft has symmetrically formed limiting grooves on its outer wall near the first limiting plate, and the first limiting plate is connected to the light rod by a slider passing through the limiting groove.

[0012] Furthermore, a first dustproof mesh is connected to one side wall of the first fan housing via a clip, and a second dustproof mesh is connected to one side wall of the second fan housing via a clip.

[0013] The beneficial effects of this invention are: Flexible folding, saving space: The two first fan housings are connected by hinges, which can be folded. When not in use or stored, the bar magnets can firmly fix the two first fan housings after folding, greatly reducing the space occupied. When in use, they can be unfolded, which is suitable for servers of different sizes and heat dissipation requirements, effectively increasing the heat dissipation area and improving the space adaptability and usage flexibility of the fan structure.

[0014] Dual cooling: Both the first fan inside the first fan housing and the second fan inside the second fan housing are axial fans. In the folded state, the second fan housing and the second fan fit tightly against the first fan housing and the first fan, which helps to increase airflow and significantly improve heat dissipation efficiency. When unfolded, it can cover a larger heat dissipation area to meet diverse heat dissipation needs and ensure stable operation of the server.

[0015] Easy installation: The strip groove on the mounting frame cooperates with the support, allowing the support to slide smoothly within the groove. The support is then fixed in place by a screw threaded to the top of the support via a fastener. The support is connected to the auxiliary heat sink via a rotatable connecting shaft. By pressing the knob to push the rod, the auxiliary heat sink can be easily folded and unfolded for easy storage and adjustment. After folding, the spring can drive the limit plate to reset and fix it, ensuring stability and making fan installation and adjustment simple and efficient. Attached Figure Description

[0026] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0027] See Figures 1-9This is a schematic diagram of the structure of the present invention, a foldable server fan structure, including two first fan housings 1 and a first fan 2. The first fan housing 1 is made of high-strength engineering plastic material, which has good insulation and corrosion resistance. Its shape is a flat square shell, and the first fan 2 is rotatably connected inside to provide sufficient heat dissipation airflow for the server. The outer wall of the first fan housing 1 is fixed with a mounting frame 4, and the top of the frame 4 has a hollow strip groove. The size of the strip groove matches the support member 5, which can ensure that the support member 5 slides smoothly in it. The support member 5 is slidably connected inside the strip groove. The top of the support member 5 is provided with an internal screw for threaded connection with a fixing member 6. The fixing member 6 is used to fix the support member 5. The side of the support member 5 away from the mounting frame 4 is rotatably connected to a connecting shaft 7. An auxiliary heat dissipation component is fixed at the bottom of the connecting shaft 7. The connecting shaft 7 is used to fold the auxiliary heat dissipation component to the top and back of the first fan housing 1.

[0028] The hinge assembly has an internal fixed limiting plate 11, which provides support for the guide rod 12 and provides an installation position for the reset component. It has a smooth through hole for sliding connection of the guide rod 12. A reset component is fixed on one side wall of the limiting plate 11. The guide rod 12 is cylindrical to ensure smooth sliding. A first limiting plate 15 is fixed on its outer wall. The first limiting plate 15 is slidably connected to the outer wall of the connecting shaft 7 in an annular shape. A second limiting plate 16 and a knob 17 are fixed at both ends of the guide rod 12, respectively. The first limiting plate 15 and the second limiting plate 16 can adjust the height of the connecting shaft 7 after it rotates on the support 5. The knob 17 is made of engineering plastic and has anti-slip texture on its surface.

[0029] A screw is fixed to one side of the top of the support member 5. During the sliding process of the support member 5 in the strip groove on the mounting frame 4, the support member 5 is fixed by the fixing member 6 and the screw. A rotating shaft is fixed to the bottom of the connecting shaft 7. The rotating shaft is used to connect the auxiliary heat dissipation component to realize the rotation function of the auxiliary heat dissipation component.

[0030] The auxiliary heat dissipation component includes a second fan housing 8, which is also made of high-strength engineering plastic. Its shape matches that of the first fan housing 1, making it easy to fold and store. A second fan 9 is rotatably connected inside the second fan housing 8. The second fan 9 has a similar structure and performance to the first fan 2, and is also an axial fan that can provide additional cooling airflow. A circular magnet is fixed at the connection between the second fan housing 8 and the first fan housing 1. It has a strong magnetic force and can ensure that the two fan housings fit tightly in the folded state. In the folded state, the second fan housing 8 and the second fan 9 can assist the first fan housing 1 and the first fan 2 in increasing airflow and improving heat dissipation efficiency. When unfolded, it is suitable for servers of different sizes and heat dissipation requirements, increasing the heat dissipation area. The top of the second fan housing 8 is connected to a rotating shaft to realize the rotation function of the second fan housing 8.

[0031] A hinge is fixed at the connection of the two mounting frames 4. The hinge is made of stainless steel and has good rotation flexibility, which can ensure that the two first fan housings 1 can be folded. A bar magnet is fixed on the front surface of the mounting frame 4 away from the hinge, which can firmly fix the two first fan housings 1 together when they are folded.

[0032] The reset assembly includes a spring 13, which has good elasticity and fatigue resistance and can maintain stable elasticity during long-term use. The spring 13 is fixed to one side wall of the limiting partition 11. A spring pressure plate 14 is fixed to the end of the spring 13 away from the limiting partition 11. The spring pressure plate 14 is used to fix one end of the spring 13. The spring pressure plate 14 compresses the spring 13 and evenly transmits the spring force to the light rod 12. The interior of the spring pressure plate 14 is connected to the light rod 12.

[0033] The connecting shaft 7 has symmetrically formed limiting grooves on its outer wall near the first limiting plate 15. The size of the limiting grooves matches the slider of the first limiting plate 15. The first limiting plate 15 is connected to the light rod 12 through the slider passing through the limiting groove, thereby limiting the connecting shaft 7.

[0034] A first dustproof net 3 is connected to one side wall of the first fan housing 1 via a clip. The first dustproof net 3 is made of fine metal mesh, which can effectively block dust from entering the fan and has good ventilation performance. The clip is made of engineering plastic and has a certain degree of elasticity, which facilitates the installation and removal of the first dustproof net 3. A second dustproof net 10 is connected to one side wall of the second fan housing 8 via a clip. The structure and function of the second dustproof net 10 are the same as those of the first dustproof net 3, and it is used to protect the second fan 9.

[0035] When using this invention: When this foldable server fan structure is in operation, it first utilizes two first fan housings 1 connected by stainless steel hinges to achieve the folding function. When not in use or needing to be stored, the two first fan housings 1 can be folded together and firmly fixed with bar magnets to reduce space occupation. When in use, it is unfolded, making it suitable for servers of different sizes and heat dissipation requirements, increasing the heat dissipation area. In the folded state, the first fan housing 1 and the second fan housing 8 fit tightly together. The second fan housing 8 and the second fan 9 assist the first fan housing 1 and the first fan 2 in increasing airflow and improving heat dissipation efficiency.

[0036] The strip groove on the mounting frame 4 cooperates with the support member 5, allowing the support member 5 to slide smoothly within it. The support member 5 is fixed in a suitable position by the screw threaded connection between the fixing member 6 and the top of the support member 5. The support member 5 is connected to the second fan housing 8 and the second fan 9 through the connecting shaft 7. The connecting shaft 7 is rotatable. The folding push knob 17 is needed to push the light rod 12 to slide inside the connecting shaft 7. During the sliding process, the spring pressure plate 14 compresses the spring 13. While sliding, the light rod 12 drives the first limit plate 15 and the second limit plate 16 to separate from the support member 5 and cancel the fixation. After the fixation is canceled, the second fan housing 8 and the second fan 9 can be folded above and behind the first fan housing 1 for easy storage and adjustment of the usage state. After the spring 13 is compressed, the spring force is evenly transmitted to the light rod 12 through the spring pressure plate 14, so that the first limit plate 15 and the second limit plate 16 are reset and engaged with the support member 5, thereby completing the fixation after folding.
