[0002] With the rapid development of computer technology, the integration and processing speed of electronic components are constantly improving, and the heat generated during operation is also increasing. In order to ensure the stable operation of the computer and extend its service life, it is often necessary to install a chassis fan to dissipate the internal heat.

[0003] In existing technologies, fans are often secured to pre-drilled holes in the chassis with nuts. While this ensures fan stability to some extent, cleaning or replacing the chassis fan requires the user to shut down the computer and remove the side or front panel of the chassis to access and operate the fan, making the entire disassembly process cumbersome. Secondly, since the fan is usually located inside the chassis and is closely connected to many electrical components, the internal components are easily subjected to bumps and vibrations during fan removal and reinstallation, which may cause them to loosen, make poor contact, or even be damaged, ultimately affecting the overall performance and stability of the computer.

Detailed Implementation

[0022] 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.

[0023] Example 1

[0024] like Figures 1 to 4 The illustrated non-disassembly chassis fan includes a housing 1, with symmetrical mounting slots 2 on the front side of the housing 1. A mounting frame 3 is slidably mounted within the mounting slots 2, and a fan 4 is mounted within the mounting frame 3. Two fixing plates 51 are provided on the front side of the inner wall of the housing 1. Y-shaped grooves 52 are provided on the fixing plates 51, and a first sliding rod 53 and a second sliding rod 54 are slidably mounted within the Y-shaped grooves 52. A lifting plate 55 connects the first sliding rod 53 and the second sliding rod 54. A first rotating shaft 58 is rotatably mounted on the outer fixing plate 51, and a second swing rod 59 is provided inside the first rotating shaft 58. The bottom of the mounting frame 3... The mounting plate 51 is symmetrically provided, and the rear side of the mounting plate 51 is connected to the lifting plate 55 through the connecting block 62; the Y-shaped groove 52 is divided into a horizontal groove 521 and an arc groove 522. The horizontal groove 521 is opened on the upper part of the fixing plate 51, and the arc groove 522 extends downward from the middle of the horizontal groove 521; the second swing rod 59 and the first swing rod 57 are rotatably connected by a second rotating shaft 60; the first slide rod 53 is located in front of the second slide rod 54; the fixing plate 51 is located on the left and right sides of the mounting groove 2; the first rotating shaft 58 extends outward through the outer shell 1 and is provided with a screwing part 7; the mounting frame 3 has heat dissipation holes 8.

[0025] This invention, by incorporating a lift-out component 5, allows users to easily remove the fan 4 from the chassis without disassembling the side or front panel, or other components around the fan 4. This greatly simplifies the cleaning and replacement process of the fan 4. Furthermore, the lift-out component 5 can operate on a single fan 4, allowing users to repair or replace specific fans as needed without extensive chassis disassembly, thus improving maintenance flexibility and efficiency. The non-disassembly design reduces the impact of chassis cover removal on internal electrical components, minimizing the risk of loosening, poor contact, or even damage. This ensures the stability of other internal components during fan 4 maintenance, guaranteeing overall computer performance. The connection between the screw-on component 7 and the lift-out component 5 allows for quick removal and installation of the fan 4 with simple operation, reducing maintenance difficulty. Even non-professional users can easily clean or replace the fan 4.

[0026] Example 2

[0027] like Figures 1 to 4The illustrated non-removable chassis fan includes a chassis shell 1, which provides robust protection for internal components such as the motherboard, processor, memory, and hard drive, preventing them from external physical impacts. It is primarily made of a metal material with good electromagnetic shielding properties. The front of the shell 1 has symmetrical mounting slots 2, within which a mounting frame 3 slides. The four corners of the mounting frame 3 can be fastened with nuts or other fasteners to install the fan 4. After installation, the fan 4 is located on the inner wall of the chassis, dissipating heat generated inside the computer, maintaining the internal electrical components at suitable operating temperatures, thereby extending the lifespan of the components and improving system stability. Therefore, the mounting frame 3 has fan-shaped annular ventilation holes 8, which, compared to ordinary perforated ventilation, can guide airflow more evenly, forming a smoother airflow channel and improving heat dissipation. It also increases the heat dissipation surface area, allowing more heat to be dissipated to the outside of the chassis through the ventilation holes 8. Furthermore, optimizing the airflow channel reduces noise generated by the fan 4 during high-speed operation, achieving a noise reduction effect.

[0028] Furthermore, the bottom of the mounting frame 3 is symmetrically equipped with insertion plates 61. The distance between the insertion plates 61 is consistent with the groove spacing of the mounting slot 2. Therefore, the mounting frame 3 can be completely inserted into the mounting slot 2 through the insertion plates 61, ensuring that the fan 4 installed on it is fixedly extended into the chassis, providing stable heat dissipation. At the same time, a lift-out component 5 is provided on the inner wall of the outer casing 1. After connecting with the insertion plates 61, the lift-out component 5 moves the insertion plates 61 and their components outward a certain distance, moving the insertion plates 61 out of the mounting slot 2. Then, it rotates the insertion plates 61 upward by 90°, exposing the fan 4, facilitating maintenance and replacement operations for the fan 4. In practical applications, the lift-out component 5 is installed according to the number of fans 4, that is, the lift-out component 5 is symmetrically installed on the inner wall of the chassis. Operators can also choose to lift out a single fan 4, making maintenance and replacement more flexible.

[0029] Example 3

[0030] like Figures 1 to 4 The illustrated non-disassembly chassis fan utilizes a lift-out component 5 installed on the inner wall of the outer casing 1. This component 5 connects to a mounting plate 61. Upon operation, it moves the mounting plate 61 and its components outwards a short distance, removing it from the mounting slot 2. Subsequently, it rotates the mounting plate 61 upwards by 90°, exposing the fan 4. This facilitates maintenance and replacement of the fan 4 by the operator. Specifically, the lift-out component 5 includes:

[0031] Fixing plates 51 are provided on the front side of the inner wall of the outer casing 1 and on both sides of the mounting groove 2. The fixing plates 51 have Y-shaped grooves 52. Specifically, the upper part of the fixing plate 51 has a horizontal groove 521, and the middle of the horizontal groove 521 extends downward to form an arc groove 522. When the first slide rod 53 and the second slide rod 54 are slidably arranged in the Y-shaped groove 52, the first slide rod 53 can be limited to the intersection of the horizontal groove 521 and the arc groove 522, while the second slide rod 54 is located at the innermost side of the horizontal groove 521, and the first slide rod 53 is located in front of the second slide rod 54. A lifting plate 55 is connected between the first slide rod 53 and the second slide rod 54. The lifting plate 55 is bent and its rear side is connected to the rear side of the insert plate 61 through a connecting plate. That is, the operation of the lifting plate 55 can drive the insert plate 61 and the fan 4 to move and lift out.

[0032] Understandably, the lifting plate 55 moves forward until the second slide rod 54 is at the front end of the transverse groove 521. At this time, the first slide rod 53 moves forward to the intersection of the transverse groove 521 and the arc groove 522. The insert plate 61 and the mounting frame 3 also move forward until the insert plate 61 is no longer located in the mounting groove 2. Then, the first slide rod 53 is rotated to slide in the arc groove 522, which drives the lifting plate 55 to rotate outward with the second slide rod 54 as the center point, and finally realizes the lifting of the lifting plate 55 and the fan 4 in the connected mounting frame 3.

[0033] Thus, a rotating rod 56 is rotatably connected between the second sliding rod 54. A first swing rod 57 is provided on the outside of the rotating rod 56. At the same time, a first rotating shaft 58 is rotatably provided on the outer fixed plate 51, located below the lifting plate 55. A second swing rod 59 is provided on the inside of the first rotating shaft 58. The second swing rod 59 and the first swing rod 57 are rotatably connected through the second rotating shaft 60. A screwing part 7 is provided through the outer shell 1 of the first rotating shaft 58. For ease of understanding, the operator can drive the first rotating shaft 58 to rotate through the screwing part 7. Then, the rotation of the first swing rod 57 will drive the second swing rod 59 and the lifting plate 55 to move forward. When the first sliding rod 53 can no longer move, the first swing rod 57 will continue to rotate, which will drive the second swing rod 59 to start rotating. That is, the lifting plate 55 will drive the fan 4 in the mounting frame 3 to be exposed, so as to cooperate with the staff to repair and replace the fan 4.
