Description

Technical Field

[0001] The present application relates to the field of liquid cooling and heat dissipation, and in particular to a liquid cooling circulation system. Background Art

[0002] In today's world of rapid technological advancement, as computer hardware performance continues to improve, heat dissipation issues have become a key factor restricting its further development. Although traditional air cooling can meet the needs of daily use to a certain extent, its heat dissipation efficiency and stability are insufficient when facing high-intensity application scenarios such as high-performance computing, gaming entertainment, and data centers. It is in this context that liquid cooling technology came into being, and with its excellent heat dissipation performance and stability, it has become the new favorite for heat dissipation in the future technology field.

[0003] Liquid cooling uses liquid as a heat transfer medium to carry heat away from the heat source and dissipate it into the external environment through the flow of liquid. Compared with traditional air cooling, liquid cooling has higher heat transfer efficiency and greater heat capacity, which can more effectively reduce the hardware temperature and ensure the stable operation of the equipment. Specifically, the liquid cooling circulation system is usually composed of coolant, cooling pipes, radiators, water pumps and other components. Driven by the water pump, the coolant flows through the heat source (such as CPU, GPU, etc.) through the cooling pipe, absorbs and carries away the heat, and then dissipates the heat into the air through the radiator.

[0004] The advantages of liquid cooling are as follows: 1. Efficient heat dissipation: Liquid cooling has a much higher heat conduction efficiency than air, which can quickly remove heat from the heat source and effectively reduce the temperature of the hardware. According to experimental data, under the same conditions, the heat dissipation efficiency of the liquid cooling circulation system can be more than 30% higher than that of the traditional air cooling system.

[0005] 2. Low noise: Since the liquid cooling circulation system does not need to rely on fans for heat dissipation, its operating noise is much lower than that of the traditional air cooling system. This is undoubtedly a great blessing for users who pursue the ultimate silent experience.

[0006] 3. Extend the life of hardware: High temperature is one of the main reasons for the aging of electronic equipment. The liquid cooling circulation system can significantly extend the service life of the hardware by effectively reducing the temperature of the hardware and reduce the performance degradation and failure rate caused by overheating.

[0007] 4. Strong adaptability: The liquid cooling circulation system is not only suitable for consumer products such as personal computers and game consoles, but also widely used in high-end fields such as data centers and supercomputers. Its powerful heat dissipation capacity can meet the needs of various high-intensity application scenarios.

[0008] In recent years, with the continuous maturity of liquid cooling technology and the gradual reduction of costs, more and more manufacturers have begun to apply it to their own products. For example, in the field of high-end gaming notebooks, some well-known brands have launched products equipped with liquid cooling circulation systems. These products not only have excellent heat dissipation performance, but also can achieve lower noise and longer battery life while ensuring performance. In addition, in the field of data centers, liquid cooling technology has also been widely used. By adopting a liquid cooling circulation system, data centers can more effectively reduce energy consumption, improve heat dissipation efficiency and reduce the impact on the environment.

[0009] The liquid cooling system mainly consists of pipes, circulation pumps and heat exchangers (radiators) as basic components. However, in order to save space inside the liquid cooling box, the common method is to place the heat exchanger outside the liquid cooling box. However, this method is limited by the flow rate of the circulation pump (too fast a flow rate will cause disturbances to the server), and its heat dissipation efficiency is low, so it is only suitable for low-power liquid-cooled servers. Summary of the invention

[0010] In order to improve the problem of low heat dissipation efficiency, the present application provides a liquid cooling circulation system.

[0011] A liquid cooling circulation system provided in the present application adopts the following technical solution: a liquid cooling circulation system, including an immersion chamber; the immersion chamber is connected to a heat dissipation circulation system, the heat dissipation circulation system includes a heat exchanger, a circulation pump, and a circulation pipeline, the heat exchanger and the circulation pump are connected in series through the circulation pipeline, the heat exchanger is located in the immersion chamber, the immersion chamber is filled with coolant, and a heat exchange medium is arranged in the heat exchanger.

[0012] Optionally, the heat exchanger includes one of a fin tube, a coil, or a fin coil.

[0013] By adopting the above technical scheme, the finned tube is mainly to add fins to the outer surface or inner surface of the ordinary tube to increase the outer surface area or inner surface area of ​​the tube, thereby increasing the heat exchange area and improving the heat exchange efficiency. The fins are in various forms, such as spiral, straight, corrugated, etc. The finned tube material generally uses stainless steel, titanium alloy, etc. to improve the corrosion resistance and high temperature resistance of the finned tube. The coil consists of a series of pipes bent into a spiral or serpentine shape. This design is not only compact and efficient, but also maximizes the contact area between the fluid and the pipe wall, thereby improving the heat exchange efficiency. Depending on the application, the coil can be divided into many types, such as spiral coil, U-shaped coil, corrugated coil, etc. Each type has its own unique advantages, such as spiral coil has better pressure resistance and heat exchange efficiency, while U-shaped coil is easier to install and maintain. Finned coil is to add fins on the basis of the coil, and the heat dissipation effect is better than that of simple finned tubes and coils.

[0014] Optionally, the heat exchanger comprises a first tube body extending in the height direction of the immersion chamber, a second tube body connected to the first tube body and extending horizontally in the length direction, and at least two groups of second tube bodies are arranged in the height direction of the immersion chamber, and a server placement space is formed between two adjacent groups of second tube bodies. The heat exchanger or part of the heat exchanger can be turned over or translated by a driving device to avoid the server.

[0015] By adopting the above technical solution, the second tube body and the coolant are both provided above and below the server for heat exchange, and the heat exchange efficiency is high. The heat exchanger or part of the heat exchanger is driven by the driving device to avoid the server so as to facilitate the removal of the server.

[0016] Optionally, the first tube body has a connecting tube extending horizontally along the width direction, and a docking port is provided on the connecting tube. Both ends of the second tube body have sliding parts that are sealed and slidably matched with the connecting tube. The immersion chamber is provided with a driving device for driving the sliding part to move, and the sliding part has a sealing part that is always in close contact with the connecting tube to include the docking port.

[0017] In order to fully exchange heat with the coolant in the immersion chamber and take away the heat of the coolant, a large number of heat exchange tubes are arranged in the existing heat exchanger in the immersion chamber. For a vertical cabinet, a multi-layer distribution is generally adopted, and the server is located between two layers of heat exchange tubes. In this way, when maintaining the server, the coolant in the immersion chamber needs to be drained first, and then the side door is opened to take out the server, and the maintenance time is long. By adopting the above technical solution, when maintaining the server, the circulation pump is first turned off, and the driving device drives the second tube body to move to the edge of the side wall of the immersion chamber to make way for the channel so that the server can be lifted out.

[0018] Optionally, the first tube body has a connecting tube that extends horizontally along the width direction as a whole, the connecting tube has an elastic deformation section, the second tube body is connected to the elastic deformation section, a guide rod is fixed in the immersion chamber, the second tube body has a sliding portion corresponding to the guide rod, and the immersion chamber is provided with a translational drive device that can drive the second tube body along the width direction.

[0019] By adopting the above technical solution, the elastic deformation section is a hollow tubular structure, and the translation drive device drives the sliding part to slide, thereby driving the second tube body to translate. When the second tube body translates, the elastic deformation section is deformed, compressed or bent. When the second tube body is close to the side wall of the immersion chamber, there is no longer any restriction on the server, and the server can be lifted at this time.

[0020] Optionally, the translation drive device includes a motor located outside the immersion chamber and a screw that rotates synchronously with an output shaft of the motor, and the screw passes through the sliding part and is threadedly connected to the sliding part.

[0021] By adopting the above technical solution, the sliding part of the second tube body can be driven to slide quickly by the motor driving the screw to rotate.

[0022] Optionally, a water-oil separator and a cache box are installed on the circulation pipeline, and the oil circuit of the water-oil separator is connected to the immersion chamber.

[0023] By adopting the above technical solution, when the seal is moved in translation, the circulation pump is turned off, and the heat exchange medium in the radiator flows into the buffer box due to gravity. In this way, when the seal fails to slide, only the oil-based coolant will enter the first pipe and the circulation pipe, and water will not enter the coolant. Optionally, both ends of the circulation pipeline extending into the immersion chamber have elastic connecting sections, and both ends of the heat exchanger are sealed and connected to the two elastic connecting sections respectively, and the heat exchanger is driven to rotate by a rotary drive device.

[0024] By adopting the above technical solution, the hoisting space for the server can be made by driving the heat exchanger to rotate.

[0025] Optionally, the coolant is an oil-based coolant or a water-based coolant or a fluorinated liquid or water, and the heat exchange medium is water.

[0026] Optionally, a radiator is installed on the circulating heat exchange path. The setting of the radiator can make the cooling medium quickly recover and improve the heat exchange effect.

[0027] Optional In summary, the present application includes at least one of the following beneficial technical effects: 1. In this solution, the heat exchanger is built into the immersion chamber, so that the coolant can directly exchange heat with the heat exchanger; 2. By setting the heat exchanger to be movable or flippable, it is convenient for the server to be hoisted and maintained. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-12 This application is described in further detail.

[0031] Embodiment 1: A liquid cooling circulation system includes an immersion chamber 1 and a heat dissipation circulation system. The immersion chamber 1 is a vertical box structure, wherein a server 2 and other heat-dissipating components are placed in the immersion chamber 1, and there is a coolant in the immersion chamber 1. There are many types of coolants, which can be divided into multiple types according to different use environments and requirements. Common coolants include water, mineral oil (including natural mineral oil, synthetic oil, silicone oil), fluorinated liquid, water-based coolant, oil-based coolant, etc.

[0032] The heat dissipation circulation system includes a heat exchanger 3, a circulation pump 4, and a circulation pipeline 5. The heat exchanger 3 and the circulation pump 4 are connected in series through the circulation pipeline 5. The heat exchanger 3 is located in the immersion chamber 1, and the immersion chamber 1 is filled with a coolant. A heat exchange medium is provided in the heat exchanger 3, and the heat exchange medium is generally water. The heat exchanger 3 or a part of the heat exchanger 3 can be turned over or translated by a driving device to avoid the server 2.

[0033] The heat exchanger 3 is preferably an aluminum alloy tube or a copper tube or a finned tube. Preferably, the heat exchanger 3 includes a first tube body extending along the height direction of the immersion chamber 1, and a second tube body 9 connected to the first tube body and extending horizontally along the length direction, and at least two groups of second tube bodies 9 are arranged along the height direction of the immersion chamber 1, and a space for placing the server 2 is formed between two adjacent groups of second tube bodies 9. The number and shape of the second tube bodies 9 here are not limited. For servers 2 with little heat, one group of second tube bodies 9 can be set. When selecting finned tubes, the number, position and shape of the fins can be designed as needed.

[0034] For example, in this embodiment, four groups of second tube bodies 9 are arranged along the height direction, and each group includes two second tube bodies 9. The first tube body has a connecting tube 10 extending horizontally along the width direction, and the first tube body is divided into a first inlet tube body 7 and a first outlet tube body 8. Both the first inlet tube body 7 and the first outlet tube body 8 have a connecting tube 10, and the connecting tube 10 is a rectangular tube. Each connecting tube 10 has two docking ports 11, and both ends of the second tube body 9 have sliding parts 12 that are sealed and slidably matched with the connecting tube 10, and the sliding part 12 has a sealing part that is always close to the connecting tube 10 and includes the docking port 11. In this embodiment, the sliding part 12 includes a rectangular frame 13 and a sliding plate 14 fixed on the rectangular frame 13, and the rectangular frame has an opening 38 connected to the second tube body 9. When working, the opening 38 completely overlaps with the docking port 11. The sealed sliding connection is mainly realized by the sealing part. In this embodiment, the sealing part is a sealing ring 15, which is embedded in the groove provided in the sliding part 12. The sealing ring 15 extends outward from the rectangular frame 13 to the sliding plate 14. The docking port 11 is always located in the sealing ring 15 during the sliding process of the sliding part 12.

[0035] Four groups of second tube bodies 9 are arranged along the height direction. In this embodiment, a server 2 is arranged between two adjacent groups of second tube bodies 9. Each server 2 is placed on a support frame 16. In this embodiment, the support frame 16 includes a first plate body 17 and a second plate body 18. The first plate body 17 is fixed to the inner wall of the immersion chamber 1. The second plate body 18 is hinged to the first plate body 17 and the intersection point is located at the upper end, so that when the first plate body 17 and the second plate body 18 are in a horizontal state on a line, the second plate body 18 can only be flipped upwards but not downwards. When the second plate body 18 is in a horizontal state in contact with the first plate body 17, the server 2 can be placed because the second plate body 18 cannot be flipped downwards. When the server 2 is taken out, the second plate body 18 flips upwards and does not interfere with the server 2. In order to facilitate the positioning of the server 2, a positioning plate 19 is fixed on the second plate body 18, and the positioning plate 19 abuts against the side wall of the server 2.

[0036] In this embodiment, the sliding parts 12 of the four second tube bodies 9 on the same straight line along the height direction of the immersion chamber 1 (i.e., the sliding parts 12 in the same vertical row) are connected together through a connecting plate 20. The translation drive device includes a motor 21 located outside the immersion chamber 1, and a screw 22 that rotates synchronously with the output shaft of the motor 21, and the screw 22 passes through the sliding part 12 and is threadedly connected to the sliding part 12. In this embodiment, since the sliding parts 12 are connected together through the connecting plate 20, only one set of motor 21 screws 22 is required. And because two of each set of second tube bodies 9 are set along the width direction of the immersion chamber 1, the screw 22 needs to be set as a bidirectional screw 22, with threads with opposite spiral directions at both ends, so as to achieve the synchronous approach or distance of the two vertical rows of second tube bodies 9. In order to make the second tube body 9 move smoothly, two bidirectional screws 22 are set, and pulleys 23 (with teeth) are fixed on the two bidirectional screws 22, and the transmission is through a toothed synchronous belt 24.

[0037] A first elastic guide sleeve 25 is installed in the docking port 11 on the connecting pipe 10 close to the first inlet pipe body 7. The first elastic guide sleeve 25 has openings at both ends, one end of which is fixedly connected to the inner wall of the docking port 11 and the other end is a free end.

[0038] The second tube body 9 is provided with a second elastic guide sleeve 26 at one end close to the first outflow tube body. The second elastic guide sleeve 26 is open at both ends, one end is fixedly connected to the inner wall of the second tube body 9, and the other end is a free end. The first elastic guide sleeve 25 and the second elastic guide sleeve 26 are made of the same material, elastic rubber. When water does not enter, the first elastic guide sleeve 25 is located in the connecting pipe 10, and the second elastic guide sleeve 26 is located in the second tube body 9. When water enters the second tube body 9 from the first inflow tube body through the connecting pipe 10, the first elastic guide sleeve 25 unfolds and partially passes through the docking port 11 to extend into the second tube body 9. The second elastic guide sleeve 26 unfolds and partially passes through the docking port 11 to extend into the connecting tube 10.

[0039] A cache box 27 is also installed on the circulation pipeline 5. The cache box has a water inlet pipe and a water outlet pipe. The first solenoid valve 28 and the first one-way valve 29 are installed on the water inlet pipe, and the second solenoid valve 30 and the second one-way valve 31 are installed on the water outlet pipe. One end of the water outlet pipe is inserted into the cache box 27 near the bottom. When the sealing test is initially performed, the first solenoid valve 28 is opened, and water flows from the cache box 27 through the second one-way valve 31 in the circulation pipe and the radiator 37 to see if there is any leakage. If there is no leakage, add coolant to the immersion chamber 1. If there is a leakage, open the first solenoid valve 28, and the water flows back to the cache box 27 through the first one-way valve 29. After the inspection is completed, test it again.

[0040] Embodiment 2: A liquid cooling circulation system, which is different from Embodiment 1 in that the first tube body has a connecting tube 10 that extends horizontally along the width direction as a whole, and the connecting tube 10 has an elastic deformation section 32, and the second tube body 9 is connected to the elastic deformation section 32. Specifically, the first tube body here is also the same as Embodiment 1, having a first inlet tube body 7 and a first outlet tube body. The meaning of the overall width direction is that while extending along the width direction, it may partially extend along the length direction of the immersion chamber 1 to form a stepped pipeline structure. The elastic deformation section 32 is also an elastic pipeline structure, and the material is consistent with the rubber band, which is a mixed material of rubber and latex. The connection between the elastic deformation section 32 and the connecting tube 10 and the second tube body 9 is sealed and connected, which can be formed by interference fit, hot melt connection, bonding or one-piece injection molding. Generally, one-piece injection molding is adopted, but for the convenience of assembly, interference fit can also be adopted.

[0041] A guide rod is fixed in the immersion chamber 1, the second tube 9 has a sliding portion 12 corresponding to the guide rod, and a translation driving device capable of driving the second tube 9 in the width direction is provided on the immersion chamber 1. Similarly, the connecting plate 20 of embodiment 1 can be used to connect the sliding portions 12 in the same vertical row together, and the driving device is the same as that of embodiment 1.

[0042] When the driving device drives the second tube body 9 to move toward the side wall of the immersion chamber 1 through the connecting plate 20 , the elastic deformation section 32 bends and deforms.

[0043] Embodiment 3: A liquid cooling circulation system, which is different from Embodiment 1 in that there are only two groups of second pipelines, which are located above and below the server 2, respectively, and the upper group of second pipelines is set to a rotatable structure, specifically as follows: both ends of the circulation pipeline 5 extending into the immersion chamber 1 have elastic connecting sections 33, and the two ends of the heat exchanger 3 are sealed and connected with the two elastic connecting sections 33 respectively. The heat exchanger 3 drives the heat exchanger 3 to rotate through a rotary drive device. The material of the elastic connecting section 33 here is consistent with the material of the rubber band, which is a mixed material of rubber and latex. The elastic connecting section 33 is a pipeline structure, which is connected to the circulation pipeline 5 and the heat exchanger 3 by an integral injection molding method. In this embodiment, the heat exchanger 3 is a serpentine coil 34 (fins can be installed on the serpentine coil 34). When the server 2 needs to be taken out, the upper heat exchanger 3 is rotated from horizontal to vertical, and the elastic connecting section 33 is located at the edge of the side wall of the immersion chamber 1. When the heat exchanger 3 is rotated to vertical, it will also be close to the edge of the side wall to make room for the server 2 to be hoisted. The rotation drive device can be a winch 35, and one end of the pull rope 36 is fixed to the side of the heat exchanger 3 away from the elastic connection section 33. When the heat exchanger 3 is in a horizontal state, the elastic connection section 33 is in a naturally expanded state, and when the heat exchanger 3 rotates, the elastic connection section 33 twists. The support frame 16 of the server 2 of this structure can be directly fixed on the inner wall of the immersion chamber 1 in a fixed manner, without the need to set a rotatable one. It can be simply understood that the second plate body 18 with the positioning plate 19 in Example 2 can be directly fixed on the inner wall of the immersion chamber 1, and the first plate body 17 can be omitted.

[0044] Embodiment 4, a liquid cooling circulation system, based on any one of the above embodiments 1-3, a radiator 37 is further installed on the external circulation pipeline, or the circulation pipeline passes through the radiator 37, and the radiator 37 can be a water cooling tower, an air cooling tower, a finned tube, etc.

[0045] In Example 1, the heat exchange medium and the cooling medium are preferably water, but this is not limited. In other embodiments, the cooling liquid and the heat exchange medium are not limited.

[0046] Other embodiments: A liquid cooling circulation system, based on any one of the above embodiments 1-4, a heat pipe 6 can also be provided on the heat exchanger 3, one end of the heat pipe 6 is connected to the heat exchanger 3, and the other end extends into a position where heat is easily accumulated.
