Description

Technical Field

[0001] This utility model relates to the field of cooling fans, specifically a cooling fan for servers. Background Technology

[0002] As a key component of the server cooling system, the server cooling fan is primarily used to quickly dissipate the heat generated during server operation, maintaining the internal components of the server within a suitable temperature range and ensuring stable and efficient server operation. During server operation, internal components such as the processor, graphics card, and power supply generate a significant amount of heat. If this heat cannot be dissipated in time, it can lead to decreased component performance, shortened lifespan, or even malfunctions, affecting the normal operation of the entire server system.

[0003] Existing cooling fans often rely solely on fan blades for heat dissipation, lacking auxiliary cooling structures such as cooling pipes and heat sink fins. The high heat generated by servers is insufficient to meet their cooling needs with simple air convection alone. Especially under high loads, heat cannot be dissipated quickly and efficiently, resulting in poor cooling and persistently high internal server temperatures. A single fan blade primarily relies on airflow generated by its rotation to remove heat from the server surface. However, the direct cooling area is limited to the surface of the server's heat-generating components and the area reached by the fan blades; the airflow distribution is uneven, easily leading to localized overheating. This single-blade cooling method suffers from low efficiency and poor cooling performance. Most existing server cooling fans are mounted on the server using screws. This method requires the use of screwdrivers and other tools to tighten each screw hole on both the fan and the server. In situations with limited internal space and a compact layout, the limited operating space and inconvenient screwdriver use make the installation process time-consuming. Furthermore, over-tightening or under-tightening the screws can affect the stability and cooling performance of the fan. Furthermore, removing the screws is cumbersome when replacing the cooling fan, increasing maintenance costs and time. Therefore, existing server cooling fans suffer from low cooling efficiency, poor heat dissipation, and difficulty in quick installation, requiring further improvement. Utility Model Content

Detailed Implementation

[0017] 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.

[0018] The following is combined Figures 1-4 This invention provides a detailed description of a cooling fan for a server:

[0019] A cooling fan for a server includes a heatsink base 1. Two mounting brackets 2 are screwed to one end of the heatsink base 1, symmetrically arranged between each bracket. Each bracket 2 houses a rotating motor 18 and fan blades 6 connected to the output of the rotating motor 18. The heatsink base 1 contains several heatsink fins 4 arranged equidistantly along its interior. A cooling pipe 3 passes through the side of the heatsink fins 4 at one end of the heatsink base 1. The bottom of the heatsink base 1 also has several snap-fit ​​components 10, each including a snap-fit ​​block 11 and a snap-fit ​​connector 15. One end of the snap-fit ​​block 11 extends outward to form an arc-shaped elastic portion 12. A guide strip 13 is provided on the side of the snap-fit ​​connector 15. The guide strip 13 extends along the side of the snap-fit ​​connector 15. One end of the snap-fit ​​connector 15 extends outward to form a snap-fit ​​part 14. The fixing frame 2 is provided with a load-bearing plate 19. The side of the load-bearing plate 19 extends outward to form several connecting rods 16. The connecting rods 16 are fixedly connected to the side of the fixing frame 2. One end of the load-bearing plate 19 extends outward to form a cylinder 17. The rotating motor 18 is located inside the cylinder 17. Several bolts 5 are provided on the surface of the fixing frame 2. A protective net 7 is also provided on the surface of the fixing frame 2. The protective net 7 is threadedly connected to the fixing frame 2 by the bolts 5. One end of the cooling pipe 3 is provided with a liquid inlet 8, and the other end of the cooling pipe 3 is provided with a liquid outlet 9. The heat dissipation fins 4 and the heat dissipation base 1 are both made of copper. Through the evenly distributed fin structure, the heat dissipation area is expanded, forming a high-efficiency heat convection channel, avoiding local heat accumulation, and improving the overall heat dissipation efficiency. The elastic part 12 provides adaptive snap-fit ​​pressure, and the guide bar 13 guides precise positioning, enabling quick installation / removal, reducing assembly difficulty and improving maintenance efficiency; the snap-fit ​​part 14 ensures a stable connection, prevents vibration-induced disengagement, and enhances mechanical reliability.

[0020] In this embodiment, the load-bearing plate 19 and cylinder 17 of the fixed frame 2 provide stable support for the rotating motor 18, ensuring the stability of the fan blades 6 during high-speed rotation. The rotating motor 18 inside the cylinder 17 is rationally arranged, saving space while improving the overall structural compactness. The design of the inlet 8 and outlet 9 of the cooling pipe 3 allows the coolant to circulate, continuously removing heat and ensuring the efficient heat dissipation performance of the cooling fan. The heat dissipation fins 4 and the heat dissipation base 1 are made of copper. Utilizing the excellent thermal conductivity of copper, heat is quickly conducted from the server to the heat dissipation fins 4 and dissipated, significantly improving heat dissipation efficiency and extending the service life of the server. The heat dissipation fins 4, evenly arranged inside the heat dissipation base 1, greatly increase the heat dissipation area and can quickly conduct the heat generated by the server. The cooling pipe 3 passes through the side of the heat dissipation fins 4, allowing direct heat exchange between the coolant inside the pipe and the fins. Combined with the fan blades 6 driven by the rotating motor 18, this forms a "liquid cooling + air cooling" composite heat dissipation mode. Compared with single air cooling, the heat is removed faster, effectively preventing the server from crashing due to high temperature. In the design of the bottom snap-fit ​​10, the arc-shaped elastic part 12 has a certain deformation capability, which can reduce the difficulty of docking during installation and facilitate quick snap-fit ​​into the corresponding mounting position of the server; the guide bar 13 can guide the snap-fit ​​connector 15 to accurately dock and avoid installation misalignment; the snap-fit ​​part 14 can form a stable limit after installation, preventing the fan from loosening during server operation vibration and ensuring long-term stability.

[0021] This embodiment of a cooling fan for a server utilizes equidistantly arranged heat dissipation fins 4 within a heatsink base 1 to effectively increase the heat dissipation area and improve heat dissipation efficiency. Cooling pipes 3 pass through the heatsink fins 4, rapidly conducting and dissipating the temperature of the coolant, further enhancing the cooling effect. The snap-fit ​​connector 10 allows the cooling fan to be directly snapped into place, enabling quick and stable installation on the server. In use, an external cooling source is connected, and coolant or cooling oil is introduced into the cooling pipes 3. The fan blades 6 are rotated by the motor 18 to dissipate heat. Heat is transferred through the heatsink base 1 and heatsink fins 4, while the coolant in the cooling pipes 3 also carries away some heat, allowing the server to cool down quickly and significantly improving heat dissipation efficiency.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
