[0002] Silent graphics card cooling fan blades are a type of fan blade specifically designed for graphics card cooling systems. They aim to provide efficient heat dissipation while minimizing noise. As graphics card performance continues to improve, the demand for heat dissipation is also increasing. These fan blades can significantly reduce noise levels while ensuring effective heat dissipation.

[0003] Existing fan blades accumulate dust and dirt over time, affecting heat dissipation and even causing them to malfunction or become damaged. Furthermore, the non-removable blades make it difficult for users to thoroughly clean the blades and surrounding area, reducing ease of use.

[0004] To address the aforementioned problems, this utility model document proposes a silent cooling fan blade for graphics cards. Utility Model Content

[0005] This invention provides a silent cooling fan blade for graphics cards, which solves the problems of existing technology where dust and dirt accumulate on the fan blades after long-term use, affecting the heat dissipation effect and even causing the fan blades to malfunction or be damaged. In addition, the non-removable fan blades make it difficult for users to thoroughly clean the fan blades and the surrounding area, reducing the convenience of use.

[0006] This utility model provides the following technical solution:

[0007] A silent cooling fan blade for a graphics card, comprising:

[0008] The bottom frame and the top frame are provided. A mounting bracket is fixedly installed on the inner wall of the bottom frame. A motor is fixedly installed on the top of the mounting bracket. A turntable is fixedly installed on the output end of the motor through a coupling. Multiple fan blade bodies are provided on the outside of the turntable.

[0009] The disassembly and assembly mechanism is located on the turntable to facilitate the disassembly and installation of the fan blade body.

[0010] In one possible design, the disassembly and assembly mechanism includes multiple inserts, an outer ring, a slot, a fixing screw, and a fixing hole. Each insert is fixedly disposed at one end of the fan blade body. The slot is opened on the outer wall of the turntable for the insert to be inserted and positioned. The outer ring is fixedly disposed on the outer wall of the insert. Each fixing screw passes through one side of the outer ring. The fixing hole is opened on the outer wall of the turntable for the fixing screw to be threaded.

[0011] In one possible design, positioning rods are symmetrically fixedly installed on the top side of the bottom frame in pairs, and positioning holes for positioning and insertion of the positioning rods are symmetrically opened on the bottom side of the top frame in pairs.

[0012] In one possible design, the top of the bottom frame has two symmetrical bottom screw holes, and the bottom of the top frame has two symmetrical top screw holes. Each bottom screw hole and top screw hole corresponds and matches, for use by threaded bolts for fixing.

[0013] In one possible design, four silicone rings are provided on the bottom side of the bottom frame and the top side of the top frame, and each silicone ring is connected to the bottom screw hole and the top screw hole.

[0014] In one possible design, a protective frame is provided on the top of the top frame, and mounting screws are symmetrically inserted through the top side of the protective frame in pairs for fixing the protective frame to the top frame.

[0015] In one possible design, each of the fan blades is shaped like a dolphin fin.

[0016] In this application, during use, the main structure of the cooling fan blade consists of a bottom frame and a top frame. A motor is fixedly installed on the top of the mounting bracket, which serves as the power source. Its output end is fixedly connected to the turntable via a coupling, thereby driving the turntable to rotate. Multiple fan blade bodies are evenly distributed on the outside of the turntable. As the multiple fan blade bodies rotate under the drive of the turntable, airflow is generated to achieve the cooling function. Each fan blade body has a fixed insertion block at one end. The insertion block matches the slot on the outer wall of the turntable, achieving initial limiting insertion. A fixing screw passes through one side of the outer ring and is threadedly connected to the fixing hole on the outer wall of the turntable, ensuring the stable installation of the fan blade body. This not only makes the installation and disassembly of the fan blade body simple and quick, but also ensures the stability and reliability of the fan blade body during rotation through the tightening effect of the fixing screw. After long-term use, it is easy to clean the dust and dirt accumulated on the fan blade, achieving a thorough cleaning effect and avoiding the fan blade from running poorly or being damaged, thus improving the convenience of use.

[0017] In addition, a positioning rod and positioning hole mating structure, as well as a combination of bottom screw holes, top screw holes, and mounting bolts, are designed between the bottom frame and the top frame to further enhance the structural stability and installation convenience of the entire heat dissipation fan blade. It also makes it easy to disassemble and remove the bottom frame and fan blade body for later cleaning. The mounting bolts not only connect and fix the bottom frame and the top frame, but also make it easy to install and fix the entire device to the corresponding graphics card position to achieve the purpose of heat dissipation for the graphics card. The silicone ring helps to reduce noise and vibration and improve the quietness effect. A protective frame is also set on the top of the heat dissipation fan blade, which is fixed to the top frame with mounting screws. The main function of the protective frame is to prevent external objects from accidentally entering the fan blade area and causing safety hazards. Each fan blade body adopts a dolphin fin-shaped design, which can effectively reduce air resistance and improve airflow efficiency, thereby further reducing the noise level while ensuring heat dissipation effect.

[0018] In this utility model, the silent cooling fan blade for graphics cards, through the disassembly and assembly mechanism, ensures the stable installation of the fan blade body, which not only makes the installation and disassembly of the fan blade body simple and quick, but also ensures the stability and reliability of the fan blade body during rotation.

[0019] In this utility model, the silent heat dissipation fan blade for graphics cards, through the setting of a positioning rod, positioning hole, bottom screw hole and top screw hole, further enhances the structural stability and installation convenience of the entire heat dissipation fan blade. It can not only connect and fix the bottom frame and the top frame, but also facilitate the installation and fixation of the entire device to the corresponding graphics card position to achieve the purpose of heat dissipation of the graphics card.

[0020] This invention not only makes the installation and disassembly of the fan blade body simple and quick, but also ensures the stability and reliability of the fan blade body during rotation. As a result, after long-term use, it is easy to clean the dust and dirt accumulated on the fan blades, achieving a thorough cleaning effect and avoiding fan blade malfunction or damage, thus improving the convenience of use.
