Description

Technical Field

[0001] The present invention relates to the field of liquid cooling technology, and in particular to a liquid cooling pipeline for a liquid cooling cabinet and a liquid cooling cabinet. Background Art

[0002] With the rapid development of information technology, the demand for computing power in fields such as data centers, high-performance computing, and artificial intelligence training clusters has exploded, and the power density of equipment has continued to rise. The power consumption of a single cabinet has soared from the traditional few kilowatts to tens of kilowatts or even higher. Traditional air cooling can no longer meet the high heat demand. In order to improve the heat dissipation effect, liquid cooling is needed.

[0003] The liquid cooling heat dissipation devices of existing cabinets are mostly composed of heat exchangers, shunt pipes, liquid cooling pipes and cooling plates. Their working principle is as follows: the shunt pipes are first connected to the external heat exchanger. The heat exchanger transports the cold liquid through the shunt pipes to the inside of each liquid cooling pipe. The liquid cooling pipes are connected to the cooling plates, and the liquid cooling pipes then transport the cold liquid to the inside of the cooling plates. At this time, the temperature of the cooling plates themselves drops and is transferred to the server, thereby achieving the purpose of liquid cooling heat dissipation.

[0004] However, if the connection between the liquid cooling pipe and the cooling plate becomes loose or broken, the coolant will leak along the connection. Although the liquid flow in the diversion pipe can be shut off in time, the remaining coolant inside the liquid cooling pipe will still leak along the gap, thereby causing damage to the electronic components. Therefore, the present application proposes a liquid cooling pipeline and a liquid cooling cabinet for a liquid cooling cabinet. Summary of the Invention

[0012] Optionally, a pair of limiting rods are provided, and the pair of limiting rods are symmetrically distributed on both sides of the side plate.

[0020] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0023] like Figure 1-Figure 5As shown, the present invention proposes a liquid cooling pipeline for a liquid cooling cabinet, comprising a plurality of liquid cooling tubes 1 for conveying liquid and a cooling plate for transferring temperature. The liquid cooling tube 1 is connected to a shunt tube 2. An external heat exchanger conveys the cooling liquid to the interior of the shunt tube 2 (the heat exchanger is not shown in this embodiment. It is a prior art and the technology is mature, so it will not be elaborated on in detail). The shunt tube 2 then conveys the cooling liquid to the interior of the plurality of liquid cooling tubes 1. In this embodiment, only one group of liquid cooling tubes 1 is shown. A support frame 3 for supporting the liquid cooling tube 1 is provided on the outside of the liquid cooling tube 1. The frame 3 supports the middle section of the liquid cooling tube 1 and also includes: a metal tube 4 connected to the liquid cooling tube 1, which then transfers the coolant to the interior of the metal tube 4. A liquid cooling tube 2 5 is installed at the end of the metal tube 4 away from the liquid cooling tube 1. The liquid cooling tube 2 5 is connected to the interface of the cooling plate, and the metal tube 4 then transfers the coolant to the interior of the liquid cooling tube 2 5. The liquid cooling tube 2 5 then transfers the coolant to the interior of the cooling plate, thereby achieving the function of heat dissipation. It should be noted that the liquid cooling tube 2 5 is made of silicone rubber and can be deformed when the pressure is above 1.5 MPa.

[0024] As an implementation method, Figure 5 and Figure 6 As shown, the liquid cooling pipeline of this embodiment also includes a pressure plate 6 and a base plate 8 for squeezing the liquid cooling tube 2 5. The base plate 8 is fixedly connected to the outer side of the metal tube 4. The trigger actuator is connected to the pressure plate 6, which is used to detect liquid leakage in the liquid cooling tube 2 5 and control the pressure plate 6 to move downward to squeeze and block the internal channel of the liquid cooling tube 2 5. When the trigger actuator senses liquid leakage at the connection between the liquid cooling tube 2 5 and the cooling plate, it will drive the pressure plate 6 to move downward, and the pressure plate 6 will move toward the base plate 8 at this time.

[0025] Further, such as Figure 6 and Figure 7 As shown, this embodiment also includes a pressure roller 7 that is rotatably installed in the pressure plate 6 and generates friction with the liquid cooling tube 2 5 when rotating, driving the liquid cooling tube 2 5 to move. When the pressure plate 6 moves down, the pressure plate 6 will synchronously drive the pressure roller 7 to move down. The pulling mechanism is connected to the pressure roller 7. When the pressure plate 6 moves down, the pulling mechanism will synchronously pull the pressure roller 7, so that the pressure roller 7 moves in a Figure 6The rotation of the pressure roller 7 will also generate a rotational friction force between the liquid cooling tube 25 and the liquid cooling tube 25 during the squeezing process. The rotational friction force can drive the liquid cooling tube 25, which has not been fully contracted, to move closer to the cooling plate before the liquid cooling tube 25 is deformed and contracted to the limit distance (similar to the working principle of the existing clamping and conveying mechanism), thereby avoiding the risk of the liquid cooling tube 25 falling off from the cooling plate when the middle part of the liquid cooling tube 25 is deformed and the distance between the two ends is shortened.

[0026] Furthermore, Figure 5 and Figure 6 As shown, the trigger actuator includes a visual sensor 9, a controller and a small cylinder 10. The trigger actuator is described in detail below: The visual sensor 9 and the controller are both installed on the outside of the pressure plate 6. The output end of the visual sensor 9 is connected to the controller. When the visual sensor 9 detects liquid leakage, it will transmit the signal to the controller. The output end of the small cylinder 10 is fixed to the top of the pressure plate 6. The output end of the controller is connected to the small cylinder 10. When the controller receives the signal, it will control the operation of the small cylinder 10 (the visual sensor 9, the controller and the small cylinder 10 are all existing technologies, and the technology is mature, so no further explanation will be given). The operation of the small cylinder 10 will drive the pressure plate 6 to move downward and move toward the direction close to the bottom plate 8.

[0027] Among them, such as Figure 6 and Figure 7 As shown, the pulling mechanism includes a traction rope 11, a pair of guide wheels 12, a pair of guide wheels 2 13, a fixing plate 14 and a through hole 15. The pulling mechanism is described in detail below: The end of the traction rope 11 is fixedly connected to the outer side of the pressure roller 7. In the initial state, the traction rope 11 is wound around the outer side of the pressure roller 7. The pair of guide wheels 1 12 are fixedly connected to the top of the pressure plate 6. The fixed plate 14 is fixedly connected to the outer side of the metal tube 4. The pair of guide wheels 2 13 are fixedly connected to the outer side of the fixed plate 14. The fixed plate 14 supports the pair of guide wheels 2 13. The outer sides of the traction rope 11 are respectively fitted with a pair of guide wheels 1 12 and a pair of guide wheels 2 13. The guide wheels 13 both guide the traction rope 11, so that the traction rope 11 is pulled in the specified direction. The through hole 15 is opened at the top of the pressure plate 6, and the traction rope 11 passes through the through hole 15. The through hole 15 provides a movable space for the traction of the traction rope 11. When the pressure plate 6 moves downward, the position of the pressure roller 7 changes synchronously, and the pressure roller 7 will apply tension to the traction rope 11. Since the distance of the traction rope 11 is limited, the traction rope 11 will move downward with the pressure roller 7, thereby driving the pressure roller 7 to rotate.

[0028] As an implementation method, Figure 6 As shown, a coil spring 28 is fixed to the outer side of the pressure roller 7, and the end of the coil spring 28 away from the pressure roller 7 is fixed to the inner wall of the pressure plate 6. When the pressure roller 7 rotates, the pressure roller 7 will apply pressure to the coil spring 28, causing the coil spring 28 to deform and generate elastic potential energy. When the pressure roller 7 moves up and resets, the coil spring 28 will release the elastic potential energy, thereby driving the pressure roller 7 to rotate in the opposite direction, and the traction rope 11 will be wrapped around the outer side of the pressure roller 7 again, so that it maintains its initial state, providing a basis for the next operation.

[0029] Further, such as Figure 8As shown, both sides of the liquid cooling tube 2 5 are provided with clamping plates 16. In the initial state, a pair of clamping plates 16 are attached to both sides of the liquid cooling tube 2 5. Both ends of the clamping plates 16 are fixed with inclined plates 17. When the pressure plate 6 moves downward, the pressure plate 6 will squeeze the inclined surface of the inclined plate 17. The inclined plate 17 will move when it is subjected to force. The outer side of the metal tube 4 is provided with an elastic clamping mechanism for supporting and resetting the clamping plate 16. The movement of the inclined plate 17 will drive the clamping plate 16 to squeeze the elastic clamping mechanism. The elastic clamping mechanism is deformed under force at this time, and the clamping plate 16 moves synchronously with the movement of the inclined plate 17, providing a movable space for the downward movement of the pressure plate 6. After the tube 2 5 is finished, when the liquid-cooling tube 2 5 itself is deformed and reset, it may cause incomplete reset, resulting in an "elliptical" shape, which in turn affects the internal flow rate of the liquid-cooling tube 2 5. The clamping plate 16 of this embodiment, after the pressure plate 6 finishes squeezing the inclined plate 17, the elastic clamping mechanism will push the clamping plate 16 to reset. When the clamping plate 16 is reset, it will contact the "elliptical" edge of the liquid-cooling tube 2 5 and apply pressure to it, so that the liquid-cooling tube 2 5 is deformed and reset to form a "circle" again, ensuring that the liquid-cooling tube 2 5 and the metal tube 4 have the same posture, avoiding the situation where the liquid inside the metal tube 4 reaches the liquid-cooling tube 2 5 and resistance occurs, thereby accelerating the flow rate of the internal liquid.

[0030] Furthermore, Figure 8 As shown, the elastic clamping mechanism includes a limit rod 18, a side plate 19, a baffle 20, a spring 21 and an L rod 22. The elastic clamping mechanism is described in detail below: The limiting rod 18 is fixedly connected to the end of the clamping plate 16 away from the liquid cooling tube 25. When the clamping plate 16 moves, it drives the limiting rod 18 to move synchronously. The side plate 19 is slidably connected to the outside of the limiting rod 18. Since the position of the side plate 19 is fixed, the limiting rod 18 moves along the inside of the side plate 19 when it moves. The baffle 20 is fixed to the end of the limiting rod 18 away from the clamping plate 16, and the baffle 20 is in contact with the end of the side plate 19 away from the limiting rod 18. The baffle 20 limits the limiting rod 18. The spring 21 is fixed between the clamping plate 16 and the side plate 19, and the two ends of the L rod 22 are fixed to the metal tube 4 and the side plate 19 respectively. When the clamping plate 16 moves, it will cooperate with the side plate 19 to apply pressure to the spring 21, causing the spring 21 to deform and generate elastic potential energy. When the clamping plate 16 finishes moving, the spring 21 will release the elastic potential energy, pushing the clamping plate 16 to reset and fit the outer side of the liquid cooling tube 2 5 again.

[0031] In addition, if Figure 8As shown, a pair of limit rods 18 are provided, and the limit rods 18 are symmetrically distributed on both sides of the side plate 19. The limit rods 18 are provided in a pair to stabilize the clamping plate 16 and avoid shaking of the clamping plate 16 when moving.

[0032] Further, such as Figure 8 As shown, the pressing roller 7 is made of silicone rubber, which has a certain hardness and a moderate friction coefficient, and is suitable for an environment in which the liquid cooling tube 2 5 is squeezed, rotated and pulled.

[0033] In addition, if Figure 7 As shown, the traction rope 11 is made of polyamide fiber and has a certain tensile strength, which is suitable for the pulling environment in this embodiment.

[0034] As an implementation method, Figures 1-8 As shown, the present application provides a liquid cooling cabinet, including a cabinet body 23, an access door 24, multiple groups of partition frames 25, a cooling plate, a slide 26, a slider 27, a liquid cooling pipe 1, a shunt pipe 2, a support frame 3, a metal pipe 4, a liquid cooling pipe 2 5, a pressure plate 6, a bottom plate 8, a trigger actuator, a pressure roller 7 and a pulling mechanism; The inspection door 24 is rotatably connected to the outside of the cabinet body 23, and the inspection door 24 can protect the interior of the cabinet body 23. Multiple groups of the partition frames 25 are fixed to the interior of the cabinet body 23. Multiple groups of partition frames 25 can be used to place cooling plates and servers. It should be noted that the server is a prior art and is not shown in this embodiment. However, no further explanation is given. The slide 26 is provided at the bottom end of the partition frame 25, and the slider 27 slides inside the slide 26. The slider 27 supports the small cylinder 10. When disassembling the server or the cooling plate, the small cylinder 10 can be separated from the interior of the cabinet body 23 by moving along the slide 26 through the slider 27, thereby avoiding the obstruction of the small cylinder 10. The trigger actuator is installed at the bottom end of the slider 27, and the cooling plate is installed at the top of the partition frame 25. The cooling plate plays a liquid cooling and heat dissipation function for the server. The liquid cooling tube 1 is installed on the outside of the shunt tube 2, and the shunt tube 2 is installed inside the cabinet body 23. The cabinet body 23 provides installation space for the internal structure. The metal tube 4 is fixedly connected to the end of the liquid cooling tube 1 away from the shunt tube 2, and the liquid cooling tube 2 5 is fixedly connected to the end of the metal tube 4 away from the liquid cooling tube 1. The liquid enters the interior of the liquid cooling tube 1 through the shunt tube 2, and then enters the interior of the cooling plate from the liquid cooling tube 1, the metal tube 4 and the liquid cooling tube 2 5. The pressure plate 6 is arranged on the outside of the liquid cooling tube 2 5, and the bottom plate 8 is fixedly connected to the outside of the metal tube 4. The trigger actuator is connected to the pressure plate 6 for detecting liquid leakage of the liquid cooling tube 2 5 and controlling the pressure plate 6 to move down to squeeze and block the internal channel of the liquid cooling tube 2 5. The pressure roller 7 is rotatably installed inside the pressure plate 6, and the pulling mechanism is used to drive the pressure roller 7 to rotate when the pressure plate 6 descends.

[0035] In this embodiment, the external heat exchanger transports the coolant to the inside of the shunt pipe 2, and the shunt pipe 2 then transports the coolant to the inside of multiple groups of liquid cooling pipes 1 respectively, and the liquid cooling pipe 1 then transfers the coolant to the inside of the metal pipe 4, and the metal pipe 4 then transfers the coolant to the inside of the liquid cooling pipe 2 5, and the liquid cooling pipe 2 5 then transfers the coolant to the inside of the cooling plate, thereby achieving the heat dissipation function. When the visual sensor 9 detects liquid leakage, it will transmit a signal to the controller, and when the controller receives the signal, it will control the operation of the small cylinder 10. The operation of the small cylinder 10 will drive the pressure plate 6 to move downward and move toward the direction close to the bottom plate 8. When the pressure plate 6 moves downward, the pressure plate 6 will synchronously drive the pressure roller 7 to move downward. In the initial state, the traction rope 11 is wrapped around the outside of the pressure roller 7. When the pressure roller 7 moves downward, the position of the pressure roller 7 changes synchronously, and the pressure roller 7 applies tension to the traction rope 11. Since the distance of the traction rope 11 is limited, the traction rope 11 will move downward with the pressure roller 7, thereby driving the pressure roller 7 to rotate. At this time, the pressure roller 7 squeezes the liquid cooling tube 2 5, and when the pressure roller 7 is squeezing, its own rotation will also drive the liquid cooling tube 2 5 toward the cooling plate, avoiding the risk of the liquid cooling tube 2 5 falling off the cooling plate when the middle part of the liquid cooling tube 2 5 is deformed to shorten the distance between the two ends. When the pressure roller 7 rotates, the pressure roller 7 applies pressure to the coil spring 28, causing the coil spring 28 to deform and generate elastic potential energy. When the pressure roller 7 moves upward and resets, the coil spring 28 will release the elastic potential energy, thereby driving the pressure roller 7 to rotate in the opposite direction, and winding the traction rope 11 around the outside of the pressure roller 7 again; When the pressure plate 6 moves downward, the pressure plate 6 will squeeze the inclined surface of the inclined plate 17, and the inclined plate 17 will move under the force. The movement of the inclined plate 17 will drive the clamping plate 16 to squeeze the spring 21, causing the spring 21 to deform and generate elastic potential energy. When the clamping plate 16 finishes moving, the spring 21 will release the elastic potential energy, pushing the clamping plate 16 to return to its original position and fit the outer side of the liquid cooling tube 2 5 again.

[0036] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
