Detailed Implementation

[0032] 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 scope of protection of the present utility model.

[0033] Figure 1 This invention provides a schematic diagram of the server chassis structure. Figure 2 A schematic diagram of the box structure in this utility model is shown. Figure 3 It shows Figure 2 Enlarged view at point A in the middle. Figure 4 It shows Figure 2 Enlarged view at point B in the middle. Figure 5 A top view of the housing in this utility model is shown. Figure 6A schematic diagram of the module bracket in this utility model is shown. Figure 7 The diagram shows the structural schematic of the server chassis cover of this utility model. The server chassis includes: a chassis 1; the chassis 1 has a mounting cavity 11 and a heat dissipation cavity 12. A first dustproof net 13 is provided on the side of the mounting cavity 11 away from the heat dissipation cavity 12, and a second dustproof net 14 is provided on the side of the heat dissipation cavity 12 away from the mounting cavity 11; a fan bracket 15 is provided in the heat dissipation cavity 12, and a plurality of fan mounting positions are provided on the fan bracket 15, each of which is equipped with a cooling fan 16; the input end of any cooling fan 16 faces the first dustproof net 13, and the output end of the cooling fan 16 faces the second dustproof net 14. When the cooling fan 16 is running, the gas in the chassis 1 flows from the first dustproof net 13 to the second dustproof net 14 to form a heat dissipation airflow. In this embodiment, both the first dustproof mesh 13 and the second dustproof mesh 14 have honeycomb-shaped mesh openings. The interior of the housing 1 is connected to the external environment through these honeycomb-shaped mesh openings, increasing the area of ​​interaction between the interior and exterior environments and improving the heat dissipation efficiency of the server chassis. The fan bracket 15 is equipped with four fan mounting positions, each corresponding to a cooling fan 16. That is, the fan bracket 15 has four cooling fans 16. The simultaneous operation of all four cooling fans 16 accelerates the airflow speed inside the housing 1, further improving the heat dissipation efficiency of the server chassis. The input end of the cooling fan 16 faces the first dustproof net 13, i.e., the mounting cavity 11, and the output end of the cooling fan 16 faces the second dustproof net 14, i.e., the external environment. Under the influence of the cooling fan 16, the gas inside the enclosure 1 flows along the cooling airflow path from the first dustproof net 13 to the second dustproof net 14 and then to the external environment. This allows the hot gas inside the enclosure 1 to flow along the cooling airflow path to the external environment. At the same time, the cooler air in the external environment enters the enclosure 1 through the first dustproof net 13. This cycle keeps the airflow inside the server enclosure, allowing the continuous airflow to carry away the heat inside the enclosure 1, which helps to accelerate the heat dissipation efficiency of the server enclosure.

[0034] Furthermore, a mounting plate 17 is provided at the bottom of the heat dissipation cavity 12, and the fan bracket 15 is fixed to the bottom of the heat dissipation cavity 12 based on the mounting plate 17. The fan bracket 15 has a mounting groove, through which the mounting plate 17 passes. The mounting plate 17 exerts a force on the fan bracket 15 under the influence of gravity, pressing the fan bracket 15 against the bottom of the heat dissipation cavity 12. This ensures that the fan bracket 15 is fixed in the corresponding position, thereby ensuring that the cooling fan 16 can drive the heated gas inside the chassis 1 to flow along the heat dissipation path to the external environment, accelerating the heat dissipation efficiency of the server chassis.

[0035] Furthermore, the mounting plate 17 has multiple grooves 171, which are distributed in parallel. In this embodiment, the mounting plate 17 has three grooves 171, which can be divided into a first groove 171, a second groove 171, and a third groove 171. The first groove 171 and the second groove 171 are located on opposite edges of the mounting plate 17, and the third groove 171 is located between the first groove 171 and the second groove 171. The first groove 171 and the second groove 171 are used to fix the fan bracket 15. A fixing part is inserted into the third groove 171 and locked in the third groove 171, so that the mounting plate 17 fits against the bottom of the mounting cavity 11. At the same time, the mounting plate 17 presses down on the bottom of the fan bracket 15, so that the fan bracket 15 is fixed in the corresponding position. This prevents the cooling fan 16 from vibrating when it is running, which would cause the fan bracket 15 to shift slightly. This helps the fan bracket 15 to remain fixed in the corresponding position.

[0036] Furthermore, the bottom of the fan bracket 15 is provided with multiple snap-fit ​​protrusions 151, which engage with corresponding grooves 171. The bottom of the fan bracket 15 has two snap-fit ​​protrusions 151, which engage with the first groove 171 and the second groove 171 on the mounting plate 17. The limiting portion restricts the movement range of the mounting plate 17, and the mounting plate 17 also restricts the movement range of the fan bracket 15. The two mutually restrict each other, fixing the fan bracket 15 in its corresponding position. Each snap-fit ​​protrusion 151 has a limiting portion at its top, which is an arc-shaped locking part. The snap-fit ​​protrusion 151 passes through the corresponding first groove 171 or second groove 171, causing the mounting plate 17 to be located below the limiting portion. When the mounting plate 17 is subjected to force and swings upward, it abuts against the limiting part, and the limiting part exerts a force on the mounting plate 17, preventing it from swinging upward further. This helps to ensure that the mounting plate 17 can be fixed on the fan bracket 15. When the cooling fan 16 rotates, it generates vibration, causing the fan bracket 15 to vibrate. The snap-fit ​​protrusion 151 on the fan bracket 15 abuts against the side wall of the first groove 171 or the second groove 171, so that when the fan bracket 15 vibrates, it can only swing in the vertical direction and cannot move in the horizontal direction. This helps to keep the fan bracket 15 fixed in the corresponding position.

[0037] Furthermore, the bottom of the mounting cavity 11 is provided with a plurality of protrusions 111 of not exactly the same shape. In this embodiment, the bottom of the mounting cavity 11 is provided with seven protrusions 111 of not exactly the same shape. The seven protrusions 111 are arranged such that they change the direction of airflow inside the housing 1, so that after part of the airflow collides with the protrusions 111, the protrusions 111 change the airflow direction towards the bottom of the circuit board, thereby allowing the airflow to contact the circuit board and carry away the heat generated by the circuit board during operation, which helps to accelerate the heat dissipation efficiency of the circuit board.

[0038] Furthermore, the bottom of the mounting cavity 11 is provided with a plurality of positioning pins 112, which are distributed between two adjacent protrusions 111. Each positioning pin 112 is used to fix the circuit board to be installed in the mounting cavity 11. Each positioning pin 112 corresponds to a fixing hole 211 on the circuit board, thereby fixing the circuit board in a designated position. The positioning pins 112 also fix the circuit board at a certain height, preventing direct contact between the bottom of the circuit board and the bottom of the mounting cavity 11. Since there is a lack of protective components such as capacitors and resistors between the circuit board and the bottom of the mounting cavity 11, it is impossible to effectively isolate and release static electricity and high-frequency interference signals, thus reducing the risk of damage to the circuit board during use.

[0039] Furthermore, a module bracket 18 is provided within the mounting cavity 11. The module bracket 18 is located on one side of the first dustproof net 13 and is connected to the first dustproof net 13. The module bracket 18 includes a first bracket 181 and a first fixing plate 182. The first fixing plate 182 is located above the first bracket 181. The first bracket 181 is provided with a plurality of spring pieces 1811. The plurality of spring pieces 1811 are used to clamp corresponding electronic components on the module bracket 18. When the corresponding electronic component is inserted into the mounting area formed by the first bracket 181, the plurality of spring pieces 1811 deform under the pressure of the electronic component and move away from the corresponding electronic component. After the corresponding electronic component is inserted into the corresponding position, the plurality of spring pieces 1811 move towards the corresponding electronic component due to their own elasticity. The plurality of spring pieces 1811 abut against the corresponding electronic component and clamp the corresponding electronic component within the mounting area. The first fixing plate 182 is provided with a triangular fixing bracket. When the corresponding electronic component is inserted into the triangular fixing bracket, the triangular fixing bracket fixes the corresponding electronic component from two sides. This is beneficial for installing the electronic component into the designated position in one step during the installation process, reducing the need for position calibration steps and improving installation efficiency.

[0040] Furthermore, the housing 1 also includes two side plates 19, each side plate 19 having a receiving platform 191; each side plate 19 has a plurality of L-shaped locking slots 192 recessed on its edge near the receiving platform 191. The two side plates 19 are symmetrically distributed on the housing 1, the receiving platform 191 is used to support components covering the housing 1, and the L-shaped locking slots 192 are used to limit the movement range of the components covering the housing 1. In this embodiment, each side plate 19 is provided with five L-shaped locking slots 192, the distance between two adjacent L-shaped locking slots 192 is equal, and the housing 1 has ten L-shaped locking slots 192. The L-shaped locking slot 192 includes a vertical groove and a horizontal groove, wherein the end of the vertical groove is connected to the beginning of the horizontal groove to form an L-shape, and the included angle between the vertical groove and the horizontal groove is 90°. The horizontal groove is used to limit the vertical movement range of the corresponding component, and the vertical groove is used to limit the horizontal movement range of the corresponding component. When the two work together, the corresponding component can only move along the side wall of the L-shaped locking position 192, preventing the corresponding component from being directly removed from the housing 1, reducing the risk of the corresponding component accidentally opening on its own, and protecting the safety of the electronic components inside the housing.

[0041] Furthermore, the server chassis also includes a cover 2, which extends from the edges of the two side panels 19 to form a connecting plate 21. The distance between two adjacent fixed protrusions is equal. When the cover 2 is closed on the chassis 1, the connecting plate 21 abuts against the receiving platform 191, that is, the receiving platform 191 supports the connecting plate 21, increasing the contact area between the connecting plate 21 and the receiving platform 191, thereby increasing the friction between the connecting plate 21 and the receiving platform 191, that is, increasing the friction between the cover 2 and the chassis 1. This prevents the cover 2 from sliding directly along the end face of the receiving platform 191, reducing the risk of the cover 2 accidentally opening on its own, and protecting the safety of the electronic components inside the chassis.

[0042] Furthermore, the connecting plate 21 is provided with the same number of fixing holes 211 as the L-shaped locking slot 192, and each fixing hole 211 is provided with a fixing boss. Each fixing hole 211 is provided with a fixing boss, which is used to cooperate with the L-shaped locking slot 192. When the fixing boss is located at the end of the horizontal groove, the side wall of the horizontal groove abuts against the fixing boss, restricting the movement range of the fixing boss, and thus restricting the movement range of the box cover 2. This ensures that the fixing boss can only move along the side wall of the L-shaped locking slot 192, preventing the box cover 2 from being directly removed from the box body 1, reducing the risk of the corresponding component opening accidentally, and protecting the safety of the items inside the box. Furthermore, when the lid 2 covers the box body 1 and the fixing boss engages with the L-shaped locking position 192, there are ten connection points between the lid 2 and the box body 1, which can increase the contact area and friction between the lid 2 and the box body 1, thereby effectively reducing the possibility of the lid 2 becoming loose or falling off during use.

[0043] In summary, this utility model, by installing a cooling fan between the first and second dustproof nets, allows gas to flow from the first dustproof net to the second dustproof net, forming a cooling airflow path. Influenced by the cooling fan, the gas inside the enclosure flows along this path from the first dustproof net to the second dustproof net and then to the external environment. This allows the heated gas inside the enclosure to flow to the external environment, while cooler air from the external environment enters the enclosure through the first dustproof net. This cycle maintains airflow inside the server enclosure, allowing continuous airflow to carry away heat from the enclosure and improve the server enclosure's heat dissipation efficiency.

[0044] Furthermore, the above description provides a detailed overview of a server chassis provided by the embodiments of this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
