[0002] A heat sink is a device that dissipates heat generated by equipment or systems to the surrounding environment through heat conduction, convection, and radiation. Its main purpose is to prevent equipment from overheating, ensuring stable operation and extending its lifespan. It consists of a heat-conducting medium, heat sink fins, a fan or water pump, and common types include air-cooled, water-cooled, and passive heat sinks, widely used in computers, automobiles, home appliances, and industrial equipment. However, the fan blades inside traditional air-cooled heat sinks often require a complex process to disassemble and assemble, often involving specialized tools and technical knowledge. This complex disassembly and assembly process can lead to additional time costs and risks, such as equipment damage or personal injury due to improper operation. Therefore, there is an urgent need for a fan blade that is easy to replace.

[0003] Currently, existing fan blades that are easy to replace cannot be adjusted in number to meet different cooling needs, making it difficult to adapt to different cooling requirements. Furthermore, when existing fan blades are damaged, the entire fan needs to be replaced, making it difficult to save on maintenance costs. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fan blade that is easy to replace, comprising an installation sleeve, wherein a plurality of blades are evenly distributed on the outer periphery of the installation sleeve, and a positioning block is provided on the inner side of the plurality of blades; the outer wall of the installation sleeve is provided with a slot adapted to the positioning block; the plurality of blades are tenon-and-mortise connected to the installation sleeve through the slot of the positioning block; and slots are symmetrically distributed on both sides of the positioning block.

[0006] Preferably, the inner walls on both sides of the card slot are provided with limiting grooves that communicate with the slot. The limiting grooves are provided with locking components, which include fixing blocks. The inner wall of the fixing blocks is connected to the outer wall of a movable rod that is adapted to it.

[0007] Preferably, one end of the movable rod is provided with a trapezoidal insert, the trapezoidal insert is disposed inside the slot, and one side of the trapezoidal insert is connected to one end of a spring.

[0008] Preferably, the other end of the spring is connected to one side of the fixed block, and the other end of the movable rod is connected to one side of the toggle block.

[0009] Preferably, a mounting frame is provided on the outer periphery of a plurality of the blades, and a protective cover is provided on one side of the mounting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This easily replaceable fan blade allows for easy installation. When blades need to be installed, the positioning block is aligned with the slot and inserted. The number of blades can be increased or decreased as needed to adapt to different heat dissipation requirements. During the insertion process, the positioning block pushes the trapezoidal insert inward, compressing the spring and engaging with the slot. The spring releases energy after engagement, causing the trapezoidal insert to automatically reset and lock into the slot. This eliminates the need for complicated installation steps to complete the blade installation. 2. The easily replaceable fan blades can be removed by extending the locking block to both sides when a single blade is damaged, requiring only the replacement of the damaged part, thus saving maintenance costs. During use, the mounting frame provides a stable support platform for the motor, and the protective net effectively prevents direct contact between the human body and the blades, thereby ensuring personnel safety.
