[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Example

[0033] See also Figure 1 , Figure 2 and Figure 3 A server chassis structure includes a chassis shell 1, which is generally in a rectangular shape and consists of a front plate 11, a rear plate 12, two side plates 13 and a cover plate 14, wherein the cover plate 14 includes a front cover 14a and a rear cover 14b, the front cover 14a is located on the front of the chassis shell 1, and the rear cover 14b is located on the rear of the chassis shell 1. The front cover 14a and the rear cover 14b are connected by a safety lock to ensure the convenience and safety of the chassis during daily maintenance or upgrades.

[0034] A front-end fan module 2 is provided on the inner side of the front plate 11 of the chassis shell 1, which is used to suck external air into the cavity of the chassis shell 1; a rear-end fan module 3 is installed on the outer side of the rear plate 12 of the chassis shell 1, which is used to discharge the air in the cavity of the chassis shell 1 to the outside of the chassis shell 1; an intermediate fan module 4 is also provided in the cavity of the chassis shell 1, and the intermediate fan module 4 divides the cavity of the chassis shell 1 into a front space and a rear space, and the intermediate fan module 4, the front-end fan module 2 and the rear-end fan module 3 are basically parallel, and the function of the intermediate fan module 4 is to quickly flow the air of the chassis shell 1 from its front space to the rear space; the above-mentioned front-end fan module 2, intermediate fan module 4 and rear-end fan module 3 are respectively connected to the intelligent control module to constitute a three-stage relay heat dissipation system of the server chassis 1, and its intelligent control module can adjust the wind strength of the control fan module in an intelligent manner.

[0035] like Figure 3 , Figure 4 and Figure 5 As shown, the middle fan module 4 includes a vertical partition 41, and the two ends of the vertical partition 41 are respectively snap-fitted with the inner walls of the two side panels 13 of the chassis shell 1, and a plurality of windows 42 are opened on the vertical partition 41, and fans 44 are installed on the windows 42. A plug interface 43 is provided on the vertical partition 41 and at the edge of each window 42. The plug interface 43 is electrically connected to the fan 44, so that the fans 44 are each powered separately.

[0036] When in use, the front fan module 2 and the middle fan module 4 can dynamically adjust the fan speed through the intelligent control module, while the fan of the rear fan module 3 can run at full speed. Therefore, the heat generated inside the chassis shell 1 can be quickly exported to the outside of the chassis through the three-stage relay cooling system to achieve a sufficient cooling effect. Each group of fan modules supports fan redundancy configuration. Even if an individual fan fails, the remaining fans can still maintain sufficient cooling capacity to ensure uninterrupted operation of the server, achieve efficient heat dissipation, and effectively prevent overheating.

[0037] Beneficial effects: The three sets of fan modules at the front, middle and rear ends of the chassis shell 1 form an efficient three-stage fan relay heat dissipation. The front and middle fans realize intelligent control functions and dynamically adjust the fan speed according to the chassis temperature to achieve heat dissipation and energy saving effects. The front fan is responsible for inhaling external cold air, and the middle fan forms a strong air duct in the cavity of the chassis shell 1 to accelerate the flow of hot air. The rear fan is responsible for discharging the hot air out of the chassis to form a three-dimensional heat dissipation cycle; it can not only guide the heat flow generated by the graphics card and various electronic components to be discharged smoothly, but also enhance the heat exchange efficiency of the entire cavity, effectively control the server operating temperature, and extend the service life of the server.

[0038] like Figure 5 , Figure 6 and Figure 7 As shown, in the front space of the chassis shell 1, a pull-out motherboard tray 5 is arranged, which can be pulled out from the opening 11a at the lower part of the front plate 11 of the chassis shell 1. Specifically, the pull-out motherboard tray 5 includes: a horizontal bottom plate 51, a vertical panel 53 and two vertical side panels 53. Among them, the horizontal bottom plate 51 of the pull-out motherboard tray 5 is parallel to the bottom wall of the chassis shell 1 and is used to install the server motherboard; a vertical panel 52 is provided at the front end of the horizontal bottom plate 51, and the vertical panel 52 is matched with the opening 11a at the lower part of the front plate 11 of the chassis shell 1, and a variety of server interfaces are arranged on the vertical panel 52; two vertical side panels 53 extend upward on both sides of the horizontal bottom plate 51, and the front end of each vertical side panel 53 is fixedly connected to the inner side of the vertical panel 52 respectively. Furthermore, two horizontal slide grooves 531 are provided on the outer wall of each vertical side panel 52, and the horizontal slide grooves 531 cooperate with the horizontal slide bars on the inner wall of the side panel 13 of the chassis shell 1, so as to slide the pull-out motherboard tray 5 and the inner wall of the side panel 13 of the chassis shell 1. In addition, pull rings 54 are provided at both ends of the outer side of the frame of the vertical panel 52 of the pull-out motherboard tray 5, respectively, so that the pull-out motherboard tray 5 can be easily pulled out from the opening 11a at the lower part of the front panel 11 of the chassis shell 1.

[0039] When installing the server motherboard, the pull-out motherboard tray 5 can be pulled out from the opening 11a at the lower part of the front plate 11 of the chassis shell 1 for motherboard installation by loosening the two screws on the server motherboard. After the installation is completed, the pull-out motherboard tray 5 is pushed into the chassis shell 1 and locked.

The preferred composite layer is a polymer material. The two ends of each crossbeam 61 are respectively fixed to the upper part of the inner wall of the side plate 13 of the chassis shell 1. Two horizontal brackets 62 are provided between the two crossbeams. Each horizontal bracket 62 includes an upper frame 62a. On the lower surface of the upper frame 62a, a side frame 62b of the horizontal bracket 62 is extended downward. The opening of the side frame 62b of the horizontal bracket 62 faces the bottom wall of the chassis shell 1. The GPU module is located in the side frame 62b of the horizontal bracket 62. The GPU module is installed in a suspended manner to facilitate heat dissipation.

[0041] Furthermore, a vertical block 62 c is provided on the outer side of the side frame 62 b of the horizontal bracket 62 , and the vertical block 62 c cooperates with a slot on the side plate 13 of the chassis shell 1 to fix the suspension device 6 to the chassis shell 1 .

Furthermore, above the extension bracket 7, two partition bars 8 are arranged, and the two ends of each partition bar 8 are respectively fixedly connected to the inner wall of the side plate 13 of the chassis shell 1, and are used for isolating the extension bracket 7 from the cover plate 14 of the chassis shell 1.

[0043] The expansion bracket 7 used to install the server graphics card adopts a clamping fixing method to ensure the safe and stable installation of the graphics card, which not only simplifies the installation process, but also improves the connection stability between the graphics card and the PCIE adapter board, avoiding poor contact problems caused by vibration.

[0044] Furthermore, the rear end of the chassis shell has four power supply bays for installing four independent power supplies, which support redundancy and hot-swap functions, allowing users to replace faulty power supply units without interrupting server operation, greatly improving the reliability and maintenance efficiency of the system.
