DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and drawings. The schematic implementation modes and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual development and use stage.

[0019] A dual-way server is a dual-CPU (central processing unit) server, also known as a dual-slot server. It is a server with two CPU slots on the server motherboard, which can be installed with two processors at the same time. The two CPUs equipped with it can process multiple tasks at the same time, which improves the calculation and operation speed; in addition, the two CPUs of a dual-way server usually have hot-swap functions. In the event of a failure of one of the two CPUs, the other server can take over the task processing, and the faulty hardware components can be replaced without interrupting the normal operation of the server, which improves the reliability of the server. However, as the performance of the CPU increases, the heat it generates also increases. In the case of poor heat dissipation, it is very easy to cause the CPU temperature to be too high, resulting in a decrease in data processing speed.

[0020] To this end, the present invention proposes a dual-channel server and a connection structure thereof, which can provide a design of a heat dissipation component to solve the problem of poor heat dissipation of the existing dual-channel server, thereby ensuring that the dual-channel server can continuously and quickly process data.

[0021] Embodiment 1: like Figures 1 to 5As shown, this embodiment provides a dual-way server, which includes a box body 1, a first CPU 21 and a second CPU 22, a first refrigeration grid plate 31 and a second refrigeration grid plate 32 are provided in the box body 1 parallel to the side plate 13 of the box body 1, and a first vertical suction fan 41 and a second vertical suction fan 42 are also provided in the box body 1, the first suction fan 41 is located on a side of the first refrigeration grid plate 31 away from the second refrigeration grid plate 32, and the second suction fan 42 is located on a side of the second refrigeration grid plate 32 away from the first refrigeration grid plate 31; The first CPU 21 is parallel to the side plate 13 and is located between the first suction fan 41 and the first refrigeration mesh plate 31 , and the second CPU 22 is parallel to the side plate 13 and is located between the second suction fan 42 and the second refrigeration mesh plate 32 ; An air intake hole 111 is provided on the bottom plate 11 of the box body 1 between the first refrigeration mesh plate 31 and the second refrigeration mesh plate 32; A first door 121 and a second door 122 that can be opened and closed are provided on the panel 12 side of the box body 1. When the first door 121 is closed, the first suction fan 41 can only suck air from between the first refrigeration grid plate 31 and the second refrigeration grid plate 32; when the second door 122 is closed, the second suction fan 42 can only suck air from between the first refrigeration grid plate 31 and the second refrigeration grid plate 32.

[0022] A vertical first rotating shaft 411 is fixedly provided on the air inlet side of the first suction fan 41, and the first suction fan 41 is rotatably connected to the box body 1 via the first rotating shaft 411; A vertical second rotating shaft 421 is fixedly provided on the air inlet side of the second suction fan 42, and the second suction fan 42 is rotatably connected to the box body 1 via the second rotating shaft 421; In the case of a failure of the first CPU 21, the first box door 121 is opened to take out the first CPU 21. At this time, the first suction fan 41 can be rotated 180° along the first rotating shaft 411 to make the first suction fan 41 blow air toward the first refrigeration mesh plate 31. In case the second CPU 22 fails, the second box door 122 is opened to take out the second CPU 22 . At this time, the second suction fan 42 can be rotated 180° along the second rotating shaft 421 to blow air toward the second refrigeration grid plate 32 .

[0023] Please refer to Figures 1 to 5It should be noted that the figure shows a scenario in which the first door 121 is unlocked and the first suction fan 41 is rotated 180° along the first rotation axis 411 when the first CPU 21 fails. When the first CPU 21 and the second CPU 22 are both working properly, the diagram on the side corresponding to the first CPU 21 can refer to the side of the second CPU 22. When the first CPU 21 and the second CPU 22 are both working properly, the first door 121 and the second door 122 are both in a closed state (at this time, the first door 121 and the second door 122 hermetically seal one side of the panel 12 of the box body 1). Figure 3 When the second suction fan 42 is sucking, in the box body 1, the air flow enters from the air inlet hole 111, then passes through the second refrigeration mesh plate 32 to be cooled, and then flows through the second CPU 22 and exchanges heat with it, so that the second CPU 22 is cooled. Thereafter, the air flow with increased temperature is sent to the outside of the box body 1 by the second suction fan 42. The air flow path on the side of the first CPU 21 participates in the heat exchange as on the side of the second CPU 22, and will not be repeated.

[0024] As for the case where the first CPU 21 fails as shown in the figure, the first CPU 21 needs to be repaired or replaced. For this purpose, the first CPU 21 is taken out. After the first CPU 21 is taken out, the data originally assigned to the first CPU 21 for processing needs to be processed by the second CPU 22, which increases the load of the second CPU 22 and dissipates more heat. If the heat dissipation condition of the second CPU 22 is not improved, the temperature may continue to rise until the second CPU 22 is damaged.

[0025] In the present embodiment, in the case of a failure of the first CPU 21, by opening the first box door 121, the airflow source of the second suction fan 42 can be partly from the air inlet through hole 111 and partly from the open side formed after the first box door 121 is opened. The airflow from the open side will first pass through the first refrigeration mesh plate 31 for primary cooling, and then pass through the second refrigeration mesh plate 32 for secondary cooling before reaching the second CPU 22. As a result, the airflow temperature reaching the second CPU 22 will be lower, which is conducive to achieving a stronger cooling effect for the high-load second CPU 22. In addition, by fixing a vertical first rotating shaft 41 on the air inlet side of the first suction fan 41 1. A vertical second rotating shaft 421 is fixedly provided on the air inlet side of the second suction fan 42. When the first CPU 21 fails, the first suction fan 41 can be rotated 180° along the first rotating shaft 411, and then the first suction fan is used to force air to the first refrigeration grid plate 31. Under the blowing action of the first suction fan, the proportion of the airflow that flows through the first refrigeration grid plate 31 and enters between the first refrigeration grid plate 31 and the second refrigeration grid plate 32 increases, that is, the proportion of the airflow that has been cooled twice in the airflow that finally reaches the second CPU 22 is larger, so that the temperature of the airflow reaching the second CPU 22 is lower, and the cooling effect brought to the second CPU 22 is better.

[0026] Embodiment 2: like Figures 1 to 7 As shown, this embodiment is based on Embodiment 1, with the difference that, in the dual-path server provided in this embodiment, a liquid collecting tank 51 is provided below the first refrigeration grid plate 31 and the second refrigeration grid plate 32, and for any liquid collecting tank 51, a derivation pipe 52 extending to the outside of the housing 1 is connected to the bottom of the liquid collecting tank 51, and one end of the derivation pipe 52 located outside the housing 1 is lower than the top of the liquid collecting tank 51, and the liquid collected in the liquid collecting tank 51 can be discharged to the outside of the housing 1 via the derivation pipe 52.

[0027] When the airflow outside the box body 1 enters the inside of the box body 1 and flows through the first refrigeration grid plate 31 and the second refrigeration grid plate 32, small water droplets will condense. By setting a collecting tank 51 and a guide pipe 52, the small water droplets can be collected and guided to the outside of the box body 1, thereby preventing them from causing harm to the first CPU 21 and the second CPU 22.

[0028] Furthermore, there is at least one sinking section in the outlet pipe 52, and the sinking section is lower than one end of the outlet pipe 52 located outside the box body 1; The air intake hole 111 is connected to two air intake pipes 53 . Any of the air intake pipes 53 passes through an outlet pipe 52 , and one end of the air intake pipe 53 away from the air intake hole 111 is located outside the box 1 .

[0029] like Figure 5 , Figure 6 As shown, the airflow enters between the first refrigeration mesh plate 31 and the second refrigeration mesh plate 32 through the air inlet pipe 53. By inserting the air inlet pipe 53 into the outlet pipe 52 and providing the outlet pipe 52 with a sinking section, the small water droplets formed by condensation can be gathered into a water accumulation area in the sinking section, and the airflow flowing through the air inlet pipe 53 can be precooled by the water in the water accumulation area, thereby helping to enhance the cooling effect of the airflow on the first CPU 21 and the second CPU 22. It should be understood that in order to enhance the precooling effect, the sinking section can be set very long.

[0030] Optionally, the section of any of the air inlet pipes 53 located inside the housing 1 is arranged in the corresponding liquid collecting tank 51. It should be understood that, in this case, the end of the outlet pipe 52 located outside the housing 1 is lower than the upper end of the liquid collecting tank 51 and higher than the bottom of the liquid collecting tank 51, so that water accumulation of a certain depth can be formed in the liquid collecting tank 51. As a result, the airflow in the air inlet pipe 53 can be pre-cooled more fully.

[0031] Preferably, vertical fins 33 are provided on both sides of the first refrigeration mesh plate 31 and both sides of the second refrigeration mesh plate 32. For any fin 33, the projection of the fin 33 along the vertical direction is located in the liquid collecting tank 51 corresponding to the fin 33. It should be understood that there are multiple fins 33 on either side of the first refrigeration mesh plate 31 and on either side of the second refrigeration mesh plate 32. The provision of the fins 33 helps to increase the "low-temperature" surface area of ​​the refrigeration mesh plate, thereby increasing the contact area between the airflow and the "low-temperature object (referring to the refrigeration mesh plate and the fins 33)", thereby enhancing the refrigeration effect on the airflow.

[0032] Preferably, Figure 7 As shown, an air distribution pipeline 54 is provided between the first refrigeration grid plate 31 and the second refrigeration grid plate 32, and the air inlet port 541 of the air distribution pipeline 54 is connected to the air inlet hole 111; the air distribution pipeline 54 can evenly distribute the air entering the box body 1 through the air inlet hole 111 between the first refrigeration grid plate 31 and the second refrigeration grid plate 32. It should be understood that the air distribution pipeline 54 is in the shape of a pipe network, and a plurality of air outlet holes are opened on each branch pipe. Accordingly, the air entering the box body 1 through the air inlet pipe 53 is distributed by the air distribution pipeline 54, so that the air entering the box body 1 can be more evenly distributed between the first refrigeration grid plate 31 and the second refrigeration grid plate 32, and the "low temperature" of each part of the refrigeration grid plate can be evenly utilized.

[0033] Embodiment 3: like Figures 1 to 7 As shown, this embodiment provides a connection structure of a dual-way server, based on the aforementioned dual-way server, specifically, Two CPU sockets (not shown in the figure) are arranged on the inner side of the back plate of the box body 1; A first slide groove 71 is provided on the top plate and / or the bottom plate 11 of the box body 1, and the first CPU 21 is slidably connected to the box body 1 through the first slide groove 71; A second slide groove 72 is provided on the top plate and / or the bottom plate 11 of the box body 1, and the second CPU 22 is slidably connected to the box body 1 through the second slide groove 72; During the process of inserting the first CPU 21 into the box 1 along the first slide groove 71, the first CPU 21 can be connected to the corresponding CPU socket. During the process of inserting the second CPU 22 into the box 1 along the second slide groove 72, the second CPU 22 can be connected to the corresponding CPU socket.

[0034] Thus, by slidingly installing the first CPU 21 and the second CPU 22 , the first CPU 21 and the second CPU 22 can be smoothly connected to the socket.

[0035] More preferably, a third slide groove 73 and a fourth slide groove 74 parallel to the first slide groove 71 are opened in the box body 1; A first gear 75 is fixedly disposed on the first rotating shaft 411 , and a second gear 76 is fixedly disposed on the second rotating shaft 421 ; A first rack 77 meshing with the first gear 75 is slidably installed in the third slide groove 73, and a second rack 78 meshing with the second gear 76 is slidably installed in the fourth slide groove 74; By sliding the first rack 77 along one end of the third sliding groove 73 to the other end, the first suction fan 41 can be switched between sucking air from the first refrigeration mesh plate 31 and blowing air to the first refrigeration mesh plate 31; The second suction fan 42 can be switched between sucking air from the second refrigeration mesh plate 32 and blowing air toward the second refrigeration mesh plate 32 by sliding the second rack 78 along one end of the fourth slide slot 74 to the other end.

[0036] More specifically, the projection of the first rack 77 along the vertical direction is located between the projection of the first gear 75 along the vertical direction and the projection of the first slide slot 71 along the vertical direction; A first connecting rod 211 is fixedly installed on the side of the first CPU 21 facing the first suction fan 41, and a first connecting portion 771 is provided on the first rack 77. When the first CPU 21 is inserted into the box body 1 along the first slide groove 71, the first connecting rod 211 can be connected to the first connecting portion 771 and push the first rack 77 to one end of the third slide groove 73. When the first CPU 21 is pulled out along the first slide groove 71, the first connecting rod 211 can pull the first rack 77 to the other end of the third slide groove 73. The projection of the second rack 78 along the vertical direction is located between the projection of the second gear 76 along the vertical direction and the projection of the second slide slot 72 along the vertical direction; A second connecting rod 221 is fixedly installed on the side of the second CPU 22 facing the second suction fan 42, and a second connecting portion 781 is provided on the second rack 78. In the process of inserting the second CPU 22 into the box body 1 along the second slide groove 72, the second connecting rod 221 can be connected to the second connecting portion 781 and push the second rack 78 to one end of the fourth slide groove 74. In the process of pulling the second CPU 22 out along the second slide groove 72, the second connecting rod 221 can pull the second rack 78 to the other end of the fourth slide groove 74.

[0037] Therefore, in the event of a failure of the first CPU 21, after opening the first box door 121, by pulling out the first CPU 21, the first rack 77 can be pulled along the third slide groove 73, thereby causing the first gear 75 to rotate. The rotation of the first gear 75 causes the first suction fan 41 to rotate 180° along the first shaft 411, thereby only providing the pulling-out action of removing the first CPU 21, and quickly switching the first fan to a mode of blowing air toward the first refrigeration grid plate 31, thereby promptly enhancing the heat dissipation of the second CPU 22 with a sudden increase in load; in the case of inserting a new first CPU 21, after inserting the new first CPU 21, the first connecting rod 211 can be connected to the first connecting portion 771, and then the first rack 77 can be pushed along the third slide groove 73 through the insertion action of the first CPU 21, thereby causing the first suction fan 41 to turn back to a mode of sucking air from the first refrigeration grid plate 31. It should be understood that in order to enable the first CPU 21 to pull the first rack 77 when it is pulled out, the connection between the first connecting rod 211 and the first connecting portion 771 should be a pre-tightening connection, such as a magnetic connection, a snap button, etc., which can disconnect the connection between the first connecting rod 211 and the first connecting portion 771 when the first connecting rod 211 is pulled outward to stop the first rack 77. The situation where the second CPU 22 fails and needs to be pulled out and replaced is similar to the situation where the first CPU 21 is pulled out and replaced, and will not be repeated here.

[0038] It should be understood that, in the present application, "rotational connection" means that the two can only rotate relative to each other, such as the rotational connection between the hole and the shaft rod, and the axial relative movement can be restricted by setting a shoulder on the shaft and a limit groove in the hole; "sliding connection" and "sliding installation" mean that the two can only slide relative to each other, such as dovetail grooves, T-slots and other structures.
