[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0017] As Figs. 1-3As shown, the detachable cooling fan blade of this utility model includes a support assembly, a fan blade assembly, and a limiting assembly. The fan blade assembly is located on the inner wall of the support assembly and is used to dissipate heat from the inside of the chassis. The limiting assembly is located on the inner wall of the support assembly and is used to limit the fan blade assembly. The limiting assembly includes a limiting frame 31, with two limiting frames 31 located at one end of the support assembly. The limiting frame 31 extends inward and has a groove 32 on its inner wall. The groove 32 extends outward and has a cooperating connecting block 33 on one side wall of the support assembly, which facilitates flexible switching between the front and back sides of the support assembly and the fan blade assembly.

[0018] Specifically, once the fan blade assembly is installed in place, the limiting bracket 31 and the connecting block 33 work together to further limit the fan blade assembly, ensuring that the fan blade body 21 remains stable during operation and will not shift or fall off due to wind or other factors.

[0019] It also includes a mounting slot 301, which is formed on the inner side wall of the support assembly to facilitate the placement of the fan blade assembly.

[0020] Specifically, the fan blade body 21 in the fan blade assembly is disposed on the upper surface of the bracket 11 of the support assembly, and the mounting groove 301 is formed in the inner side wall of the frame 13 of the support assembly, providing a placement space for the fan blade assembly. During installation, the fan blade body 21 is placed in the mounting groove 301, and the frame 13 is used to initially limit the fan blade body 21 to prevent it from moving at will.

[0021] The fan blade assembly includes a fan blade body 21, which is located on the upper surface of the support assembly to facilitate heat dissipation from the chassis.

[0022] Specifically, because the groove 32 of the limiting frame 31 and the connecting block 33 cooperate with each other, and the connecting block 33 is located on one side wall of the frame 13, this structural design allows the support assembly and the fan blade assembly to flexibly switch between the front and back sides. When the equipment needs to adjust its working mode under different operating conditions, such as when high wind pressure is required for centralized heat dissipation in a confined space, the fan blade body 21 can be turned to face the wind on one side; while in an open environment where a large air volume is required for air circulation, the fan blade body 21 can be flipped to face the wind on the other side. By releasing the cooperation between the limiting frame 31 and the connecting block 33, flipping the fan blade assembly, and then re-limiting it, the switching between the front and back sides can be completed, allowing the equipment to maintain a high energy efficiency ratio under different operating conditions.

[0023] It also includes a contact body 22, which is located at one end of the support assembly and is used to make an electrical connection with an external power source.

[0024] Specifically, the contact body 22 is located at one end of the bracket 11 of the support assembly and is used for electrical connection with an external power supply. When the cooling fan is installed in the device, the contact body 22 contacts the power interface inside the device to provide power to the cooling fan, enabling it to operate normally and achieve the heat dissipation function.

[0025] The support assembly includes a bracket 11 and a frame 13. The frame 13 is located on the upper surface of the bracket 11 and is used to limit the position of the fan blade body 21. A connecting block 33 is located on one side wall of the frame 13, and a mounting groove 301 is located on the inner side wall of the frame 13. The fan blade body 21 is located on the upper surface of the bracket 11, and the contact body 22 is located at one end of the bracket 11. One end of the frame 13 is provided with a positioning frame 12 corresponding to the bracket 11. The positioning frame 12 is located on the upper surface of the frame 13, and two limiting frames 31 are located at one end of the bracket 11.

[0026] Specifically, the bracket 11 serves as the basic support structure, and the frame 13 is located on the upper surface of the bracket 11. Together, they provide a stable mounting platform for the fan blade assembly. The positioning frame 12 is located on the upper surface of the frame 13 and corresponds to the bracket 11, further enhancing the stability and positioning accuracy of the overall structure, ensuring the accurate positioning of the fan blade assembly during operation, and reducing vibration and displacement.

[0027] The limiting frame 31 extends outward and has an arc-shaped edge 1, which is located at one end of the limiting frame 31.

[0028] Specifically, the outward extension of the arc-shaped edge 1 of the limiting bracket 31 not only increases the structural strength of the limiting component, but may also play a certain role in guiding airflow during the rotation of the fan blade assembly, thus optimizing the heat dissipation effect.

[0029] By using the groove 32 of the limiting component and the connecting block 33 in combination, the front and back of the fan blade assembly can be quickly switched, so that the same fan can have two working modes: high wind pressure centralized heat dissipation and large air volume circulation. This significantly improves the energy efficiency ratio of the equipment in different application scenarios, and is especially suitable for the adaptive needs of enclosed spaces and open environments.

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.
