[0002] Most server chassis on the market currently have their cooling mechanisms installed directly inside the chassis. When the internal temperature of the chassis cannot be dissipated in time, the cooling mechanism will increase its output power to dissipate the heat inside the chassis. However, the increased output power of the cooling mechanism will generate vibration, causing the cooling mechanism to collide with the server chassis and generate noise. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides a low-noise server chassis. By setting a noise reduction mechanism, the noise reduction mechanism absorbs the vibration generated when the heat dissipation mechanism is working, so as to reduce the noise generated by the collision of the heat dissipation mechanism.

[0009] Preferably, two adjacent cooling fan mounting positions are provided with a partition, and the partition is provided with an H-shaped rib.

[0019] This invention reduces noise generated by the collision of the heat dissipation mechanism by absorbing vibrations generated during its operation from multiple directions through a noise reduction mechanism provided on the side wall of the heat dissipation mechanism. Furthermore, the noise reduction mechanism includes a reset part and a telescopic frame. During operation, the heat dissipation mechanism compresses the telescopic frame, which in turn stretches the reset spring.

Detailed Implementation

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Figure 1 This diagram shows a first structural schematic of the low-noise server chassis of this invention. Figure 2 This diagram shows a second structural schematic of the low-noise server chassis of this invention. Figure 3 It shows Figure 2 Enlarged view of point A in the image. Figure 4 A schematic diagram of the noise reduction mechanism in this utility model is shown. Figure 5A cross-sectional view of the low-noise server chassis of this utility model is shown. The server chassis includes: a chassis body 1; the chassis body 1 has a mounting cavity 10, in which a heat dissipation mechanism 11 and a plurality of noise reduction mechanisms 12 disposed on the side wall of the heat dissipation mechanism 11 are arranged; the noise reduction mechanism 12 includes a telescopic frame 121 and a reset part 122, the top of the telescopic frame 121 is connected to the side wall of the noise reduction mechanism 12, and the bottom of the telescopic frame 121 is connected to the mounting cavity 10; the telescopic frame 121 has a plurality of hinges, and the two ends of the reset part 122 are respectively connected to two opposite hinges among the plurality of hinges to form a buffer space to absorb the vibration generated by the noise reduction mechanism 12. In this embodiment, two types of noise reduction mechanisms 12 are provided within the mounting cavity 10. These mechanisms consist of two sidewall noise reduction mechanisms 12 and four bottom noise reduction mechanisms 12. The two sidewall noise reduction mechanisms 12 are located at opposite ends of the heat dissipation mechanism 11. One end of one of the sidewall noise reduction mechanisms 12 is connected to the heat dissipation mechanism 11, and the other end is connected to the sidewall of the mounting cavity 10. One end of each of the four bottom noise reduction mechanisms 12 is connected to the bottom of the heat dissipation mechanism 11, and the other end is connected to the bottom of the mounting cavity 10. The three noise reduction mechanisms 12 are connected to the heat dissipation mechanism 11 from three different locations, which helps absorb the vibrations generated by the heat dissipation mechanism 11 during operation, thereby reducing the noise generated by the collision of the heat dissipation mechanism 11. The reset part 122 is used to reset the telescopic frame 121. When the heat dissipation mechanism 11 shakes during operation, the heat dissipation mechanism 11 pushes the noise reduction mechanism 12, causing the telescopic frame 121 in the noise reduction mechanism 12 to compress. After the telescopic frame 121 is compressed, it exerts a force on the reset part 122. The reset part 122 absorbs this force and exerts a reaction force on the telescopic frame 121, causing it to reset to the position when the noise reduction mechanism 12 is not in operation. The three noise reduction mechanisms 12 absorb the vibration generated by the heat dissipation mechanism 11 during operation from three positions simultaneously to reduce the noise generated by the collision of the heat dissipation mechanism 11.

[0029] Furthermore, the telescopic frame 121 has four hinge points, which can be divided into a first hinge point, a second hinge point, a third hinge point, and a fourth hinge point. The first and third hinge points are symmetrical about the lines on which the second and fourth hinge points lie, and the second and fourth hinge points are also symmetrical about the lines on which the first and third hinge points lie. That is, both ends of the reset part 122 are connected to the first and third hinge points respectively to form buffer spaces to absorb the vibrations generated by the noise reduction mechanism 12, or both ends of the reset part 122 are connected to the second and fourth hinge points respectively to form buffer spaces to absorb the vibrations generated by the noise reduction mechanism 12.

[0030] It should be noted that the reset part 122 can be a reset spring or a drive cylinder, and the bottom noise reduction mechanism 12 will be used as an example for explanation. When the two ends of the reset spring are connected to the first hinge and the third hinge respectively, the telescopic frame 121 is compressed by the heat dissipation mechanism 11. The compression of the telescopic frame 121 further compresses the reset spring, and the reset spring exerts a force on the telescopic frame 121, causing it to reset to the position where the noise reduction mechanism 12 is in its natural, non-operating state. During this process, the reset spring absorbs the vibration generated by the heat dissipation mechanism 11 during operation, thereby reducing the noise generated by the collision of the heat dissipation mechanism 11. Similarly, when the two ends of the reset spring are connected to the second hinge and the fourth hinge respectively, the telescopic frame 121 is compressed and then stretches the reset spring. The reset spring exerts a force on the telescopic frame 121, causing it to reset to the position where the noise reduction mechanism 12 is in its natural, non-operating state. During this process, the reset spring absorbs the vibration generated by the heat dissipation mechanism 11 during operation, thereby reducing the noise generated by the collision of the heat dissipation mechanism 11. Similarly, the working principle of the drive cylinder is similar to that of the return spring, so it will not be described in detail here.

[0031] Furthermore, the heat dissipation mechanism 11 is provided with multiple cooling fan mounting slots 111, which are arranged in a row, with equal distances between adjacent cooling fan mounting slots 111. In this embodiment, the heat dissipation mechanism 11 is provided with six cooling fan mounting slots 111, meaning six cooling fans can be installed on the heat dissipation mechanism 11. The simultaneous operation of the six cooling fans can promptly blow the dissipated heat out of the server chassis, which is beneficial for timely reducing the temperature of the server chassis. The arrangement of the six cooling fans in a row and the equal distance between adjacent cooling fan mounting slots 111 can significantly enhance the airflow inside the chassis by increasing the number of fans and the area covered by the cooling fans, thereby more effectively removing the heat inside the chassis. Moreover, this layout can form a continuous airflow channel within the chassis body 1, ensuring that heat can be quickly expelled from the chassis and reducing the internal temperature.

[0032] Furthermore, a partition 112 is provided between adjacent fan mounting slots 111, and the partition 112 is provided with H-shaped ribs. The partition 112 separates each fan, allowing each fan to focus more on its assigned cooling area, avoiding mutual airflow interference and the formation of eddies and turbulence. This helps ensure a smoother and more orderly airflow, thereby improving cooling efficiency. The H-shaped ribs on the partition 112 strengthen the connection between the partition 112 and the corresponding fan, enhancing the stability of the internal structure of the chassis. This prevents structural loosening or deformation caused by fan vibration or airflow impact, which could lead to the fan detaching from the mounting slot 111 and causing repeated collisions and noise from the fan. This reduces the risk of the fan detaching from the mounting slot and reduces the noise generated by the collisions of the cooling mechanism 11.

[0033] Furthermore, a buffer pad is provided on each sidewall where the heat dissipation mechanism 11 and the noise reduction mechanism 12 abut. The buffer pad is used to absorb and disperse vibration energy. When the heat dissipation mechanism 11 operates, it generates vibrations, which are directly transmitted to the noise reduction mechanism 12, causing resonance and thus generating noise. By providing buffer pads on the abutting sidewalls, the transmission of such vibrations can be effectively reduced, thereby reducing noise generation. The buffer pad forms a flexible connecting layer between the heat dissipation mechanism 11 and the noise reduction mechanism 12, which helps to enhance the connection stability between the two and reduce loosening or damage caused by vibration or external forces.

[0034] Furthermore, the noise reduction mechanism 12 also includes multiple limiting rods 123, which are located on both sides of the telescopic frame 121; a rubber strip is provided at the top of each limiting rod 123. In this embodiment, the noise reduction mechanism 12 is also provided with two limiting rods 123, which are used to limit the extension and retraction of the telescopic frame 121, preventing the telescopic frame 121 from being compressed to an excessively long stroke, causing the reset part 122 to be subjected to excessive force, resulting in the reset part 122 exceeding its elastic limit and failing to return to its original size. This helps to extend the service life of the reset part 122, that is, to extend the service life of the noise reduction mechanism 12. The rubber strip forms a flexible connecting layer between the limiting rod 123 and the telescopic frame 121, reducing the risk of damage to the limiting rod 123 caused by external forces.

[0035] Furthermore, the mounting cavity 10 is also provided with a hard disk assembly rack 13 and a functional module mounting rack 14. The hard disk assembly rack 13 is installed at one end of the mounting cavity 10, and the functional module mounting rack 14 is installed at the other end of the mounting cavity 10. The hard disk assembly rack 13 is used to install the hard disks required by the server, and the functional module mounting rack 14 is used to install various functional modules of the server, ensuring that the server has the corresponding functions to operate.

[0036] Furthermore, the heat dissipation mechanism 11 is located between the hard disk assembly rack 13 and the functional module mounting rack 14, with the input end of the heat dissipation mechanism 11 facing the hard disk assembly rack 13 and the output end of the heat dissipation mechanism 11 facing the functional module mounting rack 14. This layout ensures that the heat dissipation mechanism 11 can effectively absorb the heat generated on the hard disk assembly rack 13 and transfer it to the functional module mounting rack 14 area, while also blowing away the heat generated on the functional module mounting rack, which is beneficial for timely heat dissipation inside the server chassis.

[0037] It should be noted that the noise reduction mechanism 12 raises the heat dissipation mechanism 11 to a preset height, and the input end of the heat dissipation mechanism 11 is directly aligned with the area of ​​the hard drive that is generating significant heat on the hard drive mounted on the hard drive assembly rack 13. This allows it to directly utilize airflow to carry away a large amount of heat, thereby quickly reducing the temperature of the hard drive. Similarly, the noise reduction mechanism 12 raises the heat dissipation mechanism 11 to a preset height, and the output end of the heat dissipation mechanism 11 directly corresponds to the area of ​​the functional module that is generating significant heat. This allows it to directly utilize airflow to carry away a large amount of heat, thereby quickly reducing the temperature of the functional module.

[0038] Furthermore, a plurality of dustproof nets 15 are provided on the side of the enclosure body 1 near the functional module mounting bracket 14. In this embodiment, seven dustproof nets 15 are provided on the enclosure body 1, and the seven dustproof nets 15 are located in different positions, effectively blocking external dust and particles from entering the server interior, avoiding problems such as hardware malfunction, power failure, and reduced heat sink performance caused by dust entering the chassis, which is beneficial to improving the reliability of the server.

[0039] Furthermore, a mounting clip 16 is provided on the side of the enclosure body 1 near the hard drive assembly point, and the mounting clip 16 has multiple engaging protrusions. The mounting clip 16 has four engaging protrusions, which are equidistant from each other, and a engaging gap is formed between adjacent engaging protrusions. When the enclosure body 1 is installed in the corresponding position, the engaging gap is filled. This increases the contact area with the mounting clip 16 and the friction between the enclosure body 1 and the mounting clip 16, which is beneficial for strengthening the connection between the two.

[0040] Furthermore, the server chassis also includes a cover 2, which is detachably mounted on top of the chassis body 1. The detachable cover 2 allows users to easily access the interior of the chassis, facilitating regular cleaning of the cooling fans, heat sinks, and dust inside the chassis. By removing the cover 2, users can inspect the layout of the cooling fans and the airflow path, and readjust the internal layout to optimize heat dissipation.

[0041] In summary, this utility model reduces noise generated by the collision of the heat dissipation mechanism by absorbing the vibration generated during its operation from multiple directions through a noise reduction mechanism provided on the side wall of the heat dissipation mechanism. Furthermore, the noise reduction mechanism includes a reset part and a telescopic frame. During operation, the heat dissipation mechanism compresses the telescopic frame, which in turn stretches the reset spring. The reset spring exerts a force on the telescopic frame, causing it to reset to its natural, non-operating position. During this process, the reset spring absorbs the vibration generated during the operation of the heat dissipation mechanism, thereby reducing noise generated by the collision of the heat dissipation mechanism.
