The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0028] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] The embodiment of the present invention provides a slide rail type quick loading and unloading server, referring to Figure 1-Figure 2 As shown, it includes a chassis 1, a computing device 2, a main controller 3, a fan 4 and a power supply 5. A detachable upper cover 501 is provided on the top of the chassis 1, and a power supply 5 is installed on the upper cover 501. The main controller 3 is installed on the outer wall of the chassis 1. A fan 4 for exhausting air outwards is provided on the back of the chassis 1. A fixed guide rail 6 is provided on the bottom of the chassis 1. A computing device 2 is provided in the chassis 1. The computing device 2 is installed on the guide rail 6 for sliding loading and unloading. The power supply 5 is electrically connected to the main controller 3 and the fan 4, and the main controller 3 is communicatively connected to the computing device 2.

[0030] When an existing server burns out, the entire server needs to be disassembled, which is troublesome and time-consuming to repair. In addition, the server is suspended during the repair process, resulting in a reduction in the total number of original servers and a decrease in computing speed, which affects the company's benefits.

[0031] In view of the above problems, the computing board 203 including the liquid cooling plate 201 is designed as an integral computing device 2 in this embodiment, and the guide rail 6 is used to assist loading and unloading. During maintenance, the computing device 2 can be directly removed for replacement, without the need to move the entire server down and then disassemble the computing boards 203 one by one for maintenance. The replaced server can be put into use quickly, so that the operating efficiency of the enterprise is effectively guaranteed. Among them, the problematic computing device 2 (for example, a computing chip 8 is burned out) can be repaired in the maintenance room later.

[0032] It should be noted that due to the variety of server models, corresponding models of computing devices 2 are pre-stored for different models of servers. During maintenance, it is only necessary to replace the problematic computing device 2 in the corresponding server with a new computing device 2.

[0033] Specifically, refer to Figure 3As shown, the computing device 2 includes a liquid cooling plate 201, a cover plate 202, a computing plate 203, a support plate 204, a front baffle 205, an upper water separator 206 and a lower water separator 207. The outer side of the bottom of the support plate 204 is provided with a guide groove 208 that matches the guide rail 6. The guide groove 208 slides relative to the guide rail 6. A plurality of liquid cooling plates 201 with a cavity 7 structure are installed on the support plate 204. The front of each liquid cooling plate 201 is airtightly covered with a cover plate 202, and a computing plate 203 is installed on the back. The computing plate 203 A plurality of computing chips 8 connected in series are embedded on the front side. A water inlet joint 209 and a water outlet joint 210 connected to the inner wall of the cavity 7 are respectively provided at the upper and lower parts of the side of the liquid cooling plate 201. An upper water divider 206 is sleeved on the water inlet joint 209, and a lower water divider 207 is sleeved on the water outlet joint 210. The water inlet joint 209 is waterproofly connected to the upper water divider 206, and the water outlet joint 210 is waterproofly connected to the lower water divider 207. A front baffle 205 is sleeved between the side of the liquid cooling plate 201 and the upper water divider 206 and the lower water divider 207.

[0034] In this embodiment, the liquid cooling plate 201, the cover plate 202, the computing plate 203, the front baffle 205, the upper water distributor 206 and the lower water distributor 207 are connected into an assembly in the order of assembly, and then the connected assembly is placed on a pallet 204. The pallet 204 is provided with a plurality of screw holes for locking the liquid cooling plate 201 which is erected laterally. The liquid cooling plate 201 is provided with threaded holes on one side of the pallet 204. The liquid cooling plate 201 can be detachably locked on the pallet 204 to form a computing device 2. The computing device 2 can be installed on the guide rail 6 in the chassis 1 for quick loading and unloading.

[0035] Among them, reference Figure 4 As shown, the computing board 203 integrates multiple FPGA computing chips 8 with super computing capabilities and is connected in series. Since the computing chips 8 will continuously generate heat during operation, a liquid cooling plate 201 is installed on the back of the computing board 203 to cool the computing chips 8.

[0036] For further reference, Figure 5 As shown, in order to improve the cooling and heat dissipation of the computing board, reduce the risk of burning of the computing chip, and reduce the frequency of server maintenance, the present invention further optimizes and improves the structure of the liquid cooling plate. Specifically, the bottom surface of the cavity 7 of the liquid cooling plate 201 is provided with a plurality of isolation strips 701 that are arranged at intervals and protrude upward to form a flow channel 702 for the computing chip 8 to dissipate heat. One end of the isolation strip 701 near the water outlet joint 210 is integrally connected to the inner wall of the cavity 7, and the other end is separated from the inner wall of the cavity 7 to form a confluence 703, so that the cold water in each of the flow channels 702 is collected in the confluence hole and flows out from the water outlet joint 210.

[0037] In this embodiment, the liquid cooling plate 201 is a cavity 7 structure made of aluminum profiles through a die-casting process. A confluence port 703 is provided in the cavity 7. The confluence port 703 is connected to the water outlet joint 210, and the cold liquid flowing into the cavity 7 from the water inlet joint 209 is evenly distributed to each flow channel 702, and is collected at the confluence port 703 and discharged from the water outlet joint 210. Among them, since each flow channel 702 is short (for example, length = 180mm), compared with the existing "S"-shaped water tank structure (for example, length = 1000mm), the time for the cold liquid to flow from one end of the flow channel 702 to the other end is very short, that is, in each flow channel 702, the same cold liquid temperature can be used to dissipate heat and cool down all the computing chips 8 on the computing board 203, effectively avoiding the defect of the existing "S"-shaped water tank structure with a large temperature difference between the cold liquid before and after, reducing the risk of burning the computing board 203, further protecting the server, and reducing the frequency of server maintenance.

[0038] The liquid cooling plate 201 is made of aluminum, which has a significant heat conduction effect. The thickness between the bottom surface of the cavity 7 and the back surface of the locked liquid cooling plate 201 should not be too thick. The thickness is usually set to 3-10mm, and the preferred thickness is 5mm, so that the computing chip 8 can be better cooled and dissipated.

[0039] Furthermore, a liquid cooling box (which can provide circulating cold water, not shown in the figure) is provided on the outside of the chassis 1, and the liquid cooling box is respectively connected to the upper water separator 206 and the lower water separator 207 to circulate the supply of cold liquid.

[0040] In an optional embodiment, when multiple liquid cooling plates 201 (for example, 3) are installed in the chassis 1, in order to better transport the cold night and reduce the complexity of installing the cold liquid transport pipe, a through hole is provided in the middle of the water inlet joint 209 and the water outlet joint 210, and the through hole can be connected with the existing water distributor structure to simultaneously divert and supply multiple liquid cooling plates 201. Specifically, the upper water distributor 206 and the lower water distributor 207 are used in this embodiment, one end of the upper water distributor 206 is connected to the liquid cooling box, and the other end is connected to the through hole of the water inlet joint 209; one end of the lower water distributor 207 is connected to the liquid cooling box, and the other end is connected to the through hole of the water outlet joint 210, so as to form a circulating supply of cold liquid.

[0041] Furthermore, the number of guide rails 6 provided in the chassis 1 is 2, and the number of guide rails 6 cooperating with the guide rails 6 is also 2, which are respectively provided on the left and right sides of the chassis 1. The left and right outer sides of the chassis 1 are respectively provided with screw through holes 101, and the left and right sides of the support plate 204 are provided with internal threaded holes 211 corresponding to the screw through holes 101, so as to lock and assemble the computing device 2. The left and right sides of the bottom of the chassis 1 are both extended outward with mounting plates 102, and each mounting plate 102 is provided with an assembly hole 103 for screw fastening.
