[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model. It can be understood that the accompanying drawings are only for reference and illustration, and are not used to limit the present utility model.

[0031] Please refer to Figures 1 to 8 , a server chassis of the present application includes multiple components such as a housing 100, a heat dissipation fan assembly 200, and a cover body 300 in its overall composition. These components are ingeniously designed to optimize the heat dissipation performance of the server and ensure a simple and efficient installation and maintenance process.

[0032] Specifically, the housing 100 is provided with an accommodation cavity 101, which provides physical protection for the entire server and its related hardware as well as a closed operating space, enabling the internal components to be arranged in an orderly manner and helping to control the internal environment to ensure the stability and safety of the operation of electronic components.

[0033] Refer to Figure 1 , Figure 3 and Figure 6 , the heat dissipation fan assembly 200 is disposed inside the accommodation cavity. It includes a frame for supporting each heat dissipation fan - the support frame 201, and a plurality of accommodation grooves 2011 for placing independent heat dissipation fans are formed at intervals within the support frame 201. This setting not only improves the air circulation efficiency but also facilitates the individual replacement and maintenance of the heat dissipation fan 202. More importantly, by installing special buckle structures 203 on both sides of the support frame 201, this assembly can be easily fixed into the chute 204 inside the housing.

[0034] Specifically, the chute 204 is not directly provided on the inner wall of the housing 100, but at a specific position on an independently provided mounting plate 102. This can reduce the pressure of the heat sink fan assembly on the outer shell wall and make the installation of the heat sink fan more stable and reliable. The design of the chute also allows the snap structure 203 to be slidably installed from top to bottom, as Figure 2 shown. For this purpose, an inlet 2041 with a larger opening is specially provided above the chute, making the entire heat dissipation system easy to disassemble and assemble.

[0035] Refer to Figure 4 . To ensure the installation accuracy and take into account possible operation errors and material expansion and contraction changes, each pair of snap structures 203 for locking is designed as a connecting column 2031 combined with a clamping portion 2032, and the size of the clamping portion 2032 is slightly larger than that of the connecting column 2031. This can ensure that the clamping portion 2032 is located inside the chute 204, making the heat sink fan assembly 200 in a laterally locked state in the housing 100, as Figure 5 shown.

[0036] Continue to refer to Figure 4 . A silicone rubber ring 2033 with elasticity is provided between the clamping portion 2032 and the connecting column 2031, and the silicone rubber ring is designed with a double-layer structure. The small space between the double-layer designs reserves space for mechanical components and effectively isolates vibrations caused by long-term use or environmental temperature differences, increasing the pressure distribution balance degree in the contact area between the snap structure and the support frame, thereby improving the connection firmness.

[0037] Furthermore, as Figure 6 shown, positioning holes 2012 are provided on both inner sides of the receiving groove 2011 of the support frame 201 where each heat sink fan 202 is placed. These positioning holes can be combined with the corresponding positioning protrusions 2021 installed on each heat sink fan to ensure that each heat sink fan can be accurately placed in the predetermined space area.

[0038] As Figure 2 and Figure 3 shown, in order to better position and stably support the structure of the entire heat sink fan assembly 200, the design of a limiting plate 205 is added on the basis of the installation structure. The limiting plate 205 is located on the left and right sides of the support frame 201 and is connected to the corresponding limiting holes (not shown in the figure) on the upper part inside the housing 100 through fasteners 206. This mechanism further increases the system stability. This can ensure that the heat sink fan assembly is in a longitudinally locked state in the housing.

[0039] It should be noted that a spring 207 is provided in the matching method of screws or other fasteners between the limiting holes and the corresponding limiting plate 205. This enables the heat sink fan assembly to adapt to different expansions of the housing or the slight movements of different materials due to temperature changes.

[0040] As Figure 7 and Figure 8 shown. The server chassis further includes a cover 300 for sealing the housing. A row of right-angled grooves - the limiting grooves 302 are provided on both side edges of the housing, and the structure of the limiting grooves 302 can be accurately matched with the limiting posts 301 provided on the inner edge of the cover.

[0041] Finally, in order to strengthen the bonding force between the cover 300 and the housing 100 and improve its covering effect, elastic latches 303 with automatic rebound properties are installed on both outer sides of the cover as an additional safety locking means, ensuring the overall enclosure of the machine and reducing the risk of unnecessary external intrusion. Through the above detailed design solutions, a server housing product integrating functionality and maintainability is formed.

[0042] During the actual operation process, when this device is in use, the overall structure of the server chassis is first observed. The server chassis includes a housing, and a certain space is formed inside the housing for installing various electronic devices, and a receiving cavity is provided for placing key components such as a cooling fan. In order to ensure that the heat can be effectively dissipated during the operation of the device, a cooling fan assembly is provided inside the housing. This cooling fan assembly includes a specially designed support frame and a plurality of cooling fans fixed on the support frame. The inside of the support frame is divided into a plurality of independent small spaces or called accommodation grooves, and each groove contains a single cooling fan to better position and protect the cooling fan unit.

[0043] The operation of the cooling fan is realized through its fixed support frame. The ingenious part of this design is that the support frame is equipped with a specific buckle structure, and corresponding chutes are provided on both sides of the inner wall of the housing. When the support frame is inserted into the chute along the vertical direction, the assembly of the cooling fan assembly can be completed through simple and convenient operations. Specifically, these chutes are provided on an independent mounting plate, and the mounting plate is connected to the inner wall of the housing, and this design ensures the structural stability and the position accuracy of the cooling fan assembly. The top of the chute is designed with an inlet for the buckle mechanism to smoothly insert into the chute, and in order to adapt to different assembly situations and ensure good contact effects, the buckle mechanism is further divided into a connecting column and a positioning part, and the latter is larger than the former to prevent the cooling fan frame from falling off.

[0044] A more detailed design is to add a silicone ring with a double-layer structure and a gap. The silicone ring is located between the clamping part and the connecting column. Through the elasticity and buffering effect provided by this silicone material, the clamping action becomes smoother, and at the same time, the problem of the position deviation of the radiator fan assembly caused by vibration is avoided. In addition, when the radiator fan is installed into the accommodating groove, the positioning protrusions that match the positioning holes ensure that the radiator fan can be accurately and firmly positioned, further improving the stability of the system. There is also an additional measure of setting a limiting plate outside the support frame. When interacting with the limiting holes and appropriate fasteners on the mounting plate, it realizes a more robust support for the entire assembly. Springs are introduced in some design versions to enhance the ability of the entire system to remain intact when facing external forces.

[0045] In addition to the cooperation between these main components, a closed system is designed between the cover and the housing: the inner edge of the cover is equipped with limiting columns to cooperate with the limiting grooves located on the edge of the housing but with a right-angled shape. In addition, the elastic latches provided on both sides of the cover plate provide additional safety guarantees, ensuring that the device cover can be safely and reliably locked in any operating environment, thereby effectively protecting the internal precision equipment and ensuring the functional requirements for the normal operation of the entire server chassis.
