Description

Technical Field

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

[0002] In today's world of rapid technological advancement, as computer hardware performance continues to improve, heat dissipation has become a key factor restricting its further development. Although the traditional air cooling method 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 away heat 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, a liquid cooling system usually consists of coolant, cooling pipes, radiators, and water pumps. Driven by a water pump, the coolant flows through the heat source (such as CPU, GPU, etc.) through the cooling pipe, absorbs and carries away 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 system can be more than 30% higher than that of the traditional air cooling system.

[0005] 2. Low noise: Since the liquid cooling 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. Liquid cooling system can significantly extend the service life of hardware by effectively reducing the temperature of hardware and reduce the performance degradation and failure rate caused by overheating.

[0007] 4. Strong adaptability: Liquid cooling systems are not only suitable for consumer products such as personal computers and game consoles, but are 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 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 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 is mainly composed of pipelines, circulation pumps and heat exchangers (radiators) as basic components. The function of the heat exchanger is to take away the heat in the high-temperature coolant after absorbing heat and transfer it to the air. This method causes the working environment near the heat exchanger to become hotter, thereby affecting the heat transfer efficiency. Although the heat exchanger is generally equipped with a fan to assist in taking away the heat in the working environment, on the one hand, the work of the fan itself will also generate heat, and on the other hand, the ambient temperature will still rise after it works for a long time. The function of the fan is only to slow down the rate of increase of the ambient temperature. Summary of the invention

[0010] In order to improve the problem of reduced heat dissipation efficiency due to ambient temperature rise, the present application provides a liquid cooling system.

[0011] The liquid cooling system provided in this application adopts the following technical solution: A liquid cooling heat dissipation system comprises an immersion chamber; two heat dissipation circulation systems are arranged outside the immersion chamber, and the two heat dissipation circulation systems are located at two relatively far positions so that the two do not interfere with each other; the heat dissipation circulation system comprises 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, and one end of the circulation pipeline is connected to the inlet of the immersion chamber, and the other end is connected to the outlet of the immersion chamber, and electric valves or solenoid valves are arranged at both ends of the circulation pipeline close to the immersion chamber, and when working, only one of the heat dissipation circulation systems works and the two systems switch to work.

[0012] By adopting the above technical solution, two sets of heat dissipation circulation systems are arranged at two relatively distant positions, which can generally be arranged at both ends of the immersion chamber. The outer wall of the immersion chamber is generally covered with heat insulation material to prevent heat from the external environment from being transferred to the immersion chamber, and then transferred to the other set of heat dissipation circulation system through the immersion chamber; when one of the heat dissipation circulation systems has low heat dissipation efficiency due to an increase in the working environment temperature, the other set of heat dissipation circulation system is replaced. The increase in the working environment temperature here is the increase in the working environment temperature caused by the heat exchanger dissipating heat to the air.

[0013] Optionally, the heat exchanger includes at least one of a fin tube, a coil, a fin coil, and a condenser.

[0014] 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.

[0015] Optionally, the heat dissipation circulation system further includes a fan, and an air outlet of the fan faces the heat exchanger.

[0016] By adopting the above technical solution, the setting of the fan can improve the heat dissipation effect on the one hand, so that the coolant dissipates heat faster, and on the other hand, it can slow down the temperature rise rate of the working environment.

[0017] Optionally, the immersion chamber is connected to a drain pipe, and a control valve is installed on the drain pipe.

[0018] By adopting the above technical solution, during maintenance, the coolant can be discharged from the drain pipe by opening the control valve, and the drain pipe can be connected to the external collecting tank.

[0019] Optionally, the liquid cooling system further includes a controller, and a plurality of temperature sensors are arranged around the heat exchanger. When the temperature sensor detects that the temperature is higher than a set value, the controller controls the switching of another cooling circulation system to operate.

[0020] By adopting the above technical solution, temperature sensors are set around the heat exchanger to detect the temperature of the working environment. When the temperature exceeds the set value, another heat dissipation circulation system is switched. This method is more intelligent and does not require manual switching.

[0021] Optionally, a heat insulation plate is fixed on the outer wall of the immersion chamber, and the heat insulation plate is located between the two heat dissipation circulation systems.

[0022] By adopting the above technical solution, the setting of the heat insulation board can avoid mutual interference between the two heat dissipation circulation systems as much as possible.

[0023] Optionally, the immersion chamber is a heat-insulating structure, and two sets of heat dissipation circulation systems are respectively located at two ends of the immersion chamber.

[0024] Optionally, a liquid-cooled heat dissipation system is provided with a heat dissipation circulation system outside the immersion chamber, the heat dissipation circulation system includes a heat exchanger, a circulation pump, and a circulation pipeline, wherein one end of the circulation pump is connected to the immersion chamber, and the other end is sealed and rotatably connected to one end of the circulation pipeline, the other end of the circulation is sealed and rotatably connected to the immersion chamber, the heat exchanger is installed on the circulation pipeline and can rotate with the circulation pipeline, and a driving device for driving the rotation of the circulation pipeline is installed outside the immersion chamber.

[0025] By adopting the above technical solution, the circulation pipeline and the heat exchanger are driven to rotate together through the driving device, so that the circulation system can be switched from one working environment to another working environment. In this way, when the temperature of the current working environment exceeds the set value, it can be switched to a new working environment through the above method.

[0026] Optionally, the driving device includes a first gear fixed on the circulation pipeline, a motor installed outside the immersion chamber, and a second gear rotating synchronously with the electric output shaft, and the first gear is meshed with the second gear.

[0027] By adopting the above technical solution, the gear transmission method is relatively simple, and a larger torque is obtained by adjusting the gear tooth ratio to drive the circulation pipeline and the heat exchanger to rotate together.

[0028] Optionally, the radiator is a finned tube. The rotating method is more suitable for the finned tube, which is light in weight and more suitable for this method.

[0029] In summary, the present application includes at least one of the following beneficial technical effects: 1. This embodiment reduces the impact of the working environment by alternately using two heat dissipation circulation systems that are set far away from each other and installing a heat insulation board; 2. The rotation method allows a heat dissipation circulation system to switch between two relatively distant positions, reducing the impact of the working environment.

[0030] 3. The heat exchange is carried out outside the immersion chamber, so that the immersion chamber can accommodate more heat dissipation devices; 4. When rapid heat dissipation is required, two heat dissipation circulation systems can be started at the same time; 5. When one of the cooling systems is damaged, the other cooling system can be used as a backup, making the system more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is combined with Figure 1-6 This application is described in further detail.

[0034] Embodiment 1: A liquid cooling system includes an immersion chamber 1, wherein a server or other heat-dissipating element is placed in the immersion chamber 1, and the immersion chamber 1 contains a coolant, and 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, fluorinated liquid, water-based coolant, oil-based coolant, etc.

[0035] Two heat dissipation circulation systems are arranged outside the immersion chamber 1. The two heat dissipation circulation systems are located at two relatively far positions so that they do not interfere with each other. When one of the heat dissipation circulation systems has low heat dissipation efficiency due to an increase in the working environment temperature, the other heat dissipation circulation system is replaced. The increase in the working environment temperature here is caused by the heat exchanger dissipating heat to the air.

[0036] The immersion chamber 1 is connected to a drain pipe 2, and a control valve 3 is installed on the drain pipe 2. During maintenance, the coolant can be discharged from the drain pipe 2 by opening the control valve 3, and the drain pipe 2 can be connected to a header tank. The control valve 3 is generally a manual valve, specifically a ball valve.

[0037] Specifically, the immersion chamber 1 is preferably in the shape of a horizontal rectangular parallelepiped, and its two heat dissipation circulation systems are located at both ends of the immersion chamber 1 along the length direction, so that the two maintain a sufficient distance and do not affect each other. For a vertical immersion chamber 1, it is best to add a heat insulation plate 4 between the two heat dissipation circulation systems. The heat insulation plate 4 can be directly fixed to the outer wall of the immersion chamber 1 (for example, bonding or welding), or it can be connected in a detachable manner for easy transportation. The detachable manner can be a plug-in or bolt connection. For example, a connecting plate is fixed on the outer wall of the immersion chamber 1, and the heat insulation plate 4 can be connected to the connecting plate by bolts and nuts. The immersion chamber 1 is a heat-insulating structure, in which the outer wall of the immersion chamber 1 is also covered with heat-insulating materials to prevent heat from the external environment from being transferred to the immersion chamber 1, and then transferred to another heat dissipation circulation system through the immersion chamber 1.

[0038] The heat dissipation circulation system includes a heat exchanger, a circulation pump 5, and a circulation pipeline 6. The heat exchanger and the circulation pump 5 are connected in series through the circulation pipeline 6, and one end of the circulation pipeline 6 is connected to the inlet of the immersion chamber 1, and the other end is connected to the outlet of the immersion chamber 1. Both ends of the circulation pipeline 6 close to the immersion chamber 1 are provided with electric valves or solenoid valves 7. In this embodiment, solenoid valves 7 are selected. When working, only one of the heat dissipation circulation systems works and the two systems switch to work. When the heat dissipation circulation system is not working, its corresponding solenoid valve 7 is closed.

[0039] The heat exchanger in this embodiment is a finned tube 8. The finned tube 8 is mainly a fin mounted on the outer surface or inner surface of an 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 material of the finned tube 8 is generally stainless steel, titanium alloy, etc. to improve the corrosion resistance and high temperature resistance of the finned tube 8. In this embodiment, the fin is in a circular shape.

[0040] The heat dissipation circulation system can be switched manually, but the best way is to use automatic switching. Specifically, multiple temperature sensors 9 are arranged around the heat exchanger. When the temperature sensor 9 detects that the temperature is higher than the set value, the controller controls to switch to another heat dissipation circulation system. For example, one can be arranged at each end of the heat exchanger, and when any temperature sensor 9 is higher than the set value, another heat dissipation circulation system is switched to work.

[0041] Since the heat dissipation efficiency of the cooling liquid using only the fin tube 8 is low, a fan 10 is configured to assist in removing the heat on the surface of the fin tube 8. The air outlet of the fan 10 faces the heat exchanger.

[0042] Embodiment 2: A liquid cooling system includes an immersion chamber 1, wherein a server or other heat-dissipating element is placed in the immersion chamber 1, and the immersion chamber 1 contains a coolant, and 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, fluorinated liquid, water-based coolant, oil-based coolant, etc.

[0043] Two heat dissipation circulation systems are arranged outside the immersion chamber 1. The two heat dissipation circulation systems are located at two relatively far positions so that they do not interfere with each other. When one of the heat dissipation circulation systems has low heat dissipation efficiency due to an increase in the working environment temperature, the other heat dissipation circulation system is replaced. The increase in the working environment temperature here is caused by the heat exchanger dissipating heat to the air.

[0044] The immersion chamber 1 is connected to a drain pipe 2, and a control valve 3 is installed on the drain pipe 2. During maintenance, the coolant can be discharged from the drain pipe 2 by opening the control valve 3, and the drain pipe 2 can be connected to a header tank. The control valve 3 is generally a manual valve.

[0045] Specifically, the immersion chamber 1 is preferably in the shape of a horizontal rectangular parallelepiped, and its two heat dissipation circulation systems are located at both ends of the immersion chamber 1 along the length direction, so that the two maintain a sufficient distance and do not affect each other. For a vertical immersion chamber 1, it is best to add a heat insulation plate 4 between the two heat dissipation circulation systems. The heat insulation plate 4 can be directly fixed to the outer wall of the immersion chamber 1 (for example, bonding or welding), or it can be connected in a detachable manner for easy transportation. The detachable manner can be a plug-in or bolt connection. For example, a connecting plate is fixed on the outer wall of the immersion chamber 1, and the heat insulation plate 4 can be connected to the connecting plate by bolts and nuts. The immersion chamber 1 is a heat-insulating structure, in which the outer wall of the immersion chamber 1 is also covered with heat-insulating materials to prevent heat from the external environment from being transferred to the immersion chamber 1, and then transferred to another heat dissipation circulation system through the immersion chamber 1.

[0046] The heat dissipation circulation system includes a heat exchanger, a circulation pump 5, and a circulation pipeline 6. The heat exchanger and the circulation pump 5 are connected in series through the circulation pipeline 6, and one end of the circulation pipeline 6 is connected to the inlet of the immersion chamber 1, and the other end is connected to the outlet of the immersion chamber 1. Electric valves or solenoid valves 7 are provided at both ends of the circulation pipeline 6 close to the immersion chamber 1. In this embodiment, solenoid valves 7 are selected. When working, only one of the heat dissipation circulation systems works and the two systems switch to work.

[0047] The heat exchanger selected in this embodiment is a coil 11. The coil 11 is composed of a series of pipes bent into a spiral or serpentine shape. This design is not only compact and efficient, but also can maximize the contact area between the fluid and the pipe wall, thereby improving the heat exchange efficiency. Depending on the application, the coil 11 can be divided into various types, such as a spiral coil 11, a U-shaped coil 11, a corrugated tube coil 11, etc. In this embodiment, a U-shaped coil 11 that bends back and forth is used to form a serpentine pipe.

[0048] The heat dissipation circulation system can be switched manually, but the best way is to use automatic switching. Specifically, multiple temperature sensors 9 are arranged around the heat exchanger. When the temperature sensor 9 detects that the temperature is higher than the set value, the controller controls to switch to another heat dissipation circulation system. For example, one can be arranged at each end of the heat exchanger, and when any temperature sensor 9 is higher than the set value, another heat dissipation circulation system is switched to work.

[0049] Since the heat dissipation efficiency of the cooling liquid using only the fin tube 8 is low, a fan 10 is configured to assist in removing the heat on the surface of the fin tube 8. The air outlet of the fan 10 faces the heat exchanger.

[0050] Embodiment 3: A liquid cooling heat dissipation system, which is different from Embodiment 2 in that the heat exchanger is replaced by a finned coil 12, that is, fins are added to the coil 11, and the heat dissipation effect is better than that of simple finned tubes 8 and coils 11.

The immersion chamber 1 adopts a heat insulation structure as in Embodiment 1, and a heat insulation board 4 is provided. A heat dissipation circulation system is provided outside the immersion chamber 1, and only one set of the heat dissipation circulation system is provided. The heat dissipation circulation system includes a heat exchanger, a circulation pump 5, and a circulation pipeline 6, wherein one end of the circulation pump 5 is connected to the immersion chamber 1, and the other end is sealed and rotatably connected to one end of the circulation pipeline 6, and the other end of the circulation is sealed and rotatably connected to the immersion chamber 1. The heat exchanger is installed on the circulation pipeline 6 and can rotate with the circulation pipeline 6. A driving device for driving the rotation of the circulation pipeline 6 is installed outside the immersion chamber 1. It should be noted that the circulation pump 5 and the immersion chamber 1 are stationary. The circulation pipeline 6 is in a use state when it is in a horizontal state, and a supporting device is provided at the bottom. The supporting device includes a bottom plate 14, and a U-shaped support ring 15 is fixed on the bottom plate 14. When it is necessary to move to another working position, it needs to be rotated 180 degrees.

[0054] The driving device uses a motor 16, a first gear 17 and a second gear 18. The first gear 17 is fixed on the circulation pipeline 6, and the second gear 18 is fixed on the output shaft of the motor 16. The first gear 17 is meshed with the second gear 18, and the circulation pipeline 6 and the heat exchanger on the circulation pipeline 6 are driven by gear transmission. In this way, the heat exchanger is generally selected to be light in weight, such as the radiator is a finned tube 8. The gear ratio of the first gear 17 to the second gear 18 is less than 1. The rotary seal adopts a multiple sealing method, such as a combination of multiple sealing rings, or a labyrinth seal. The sealing ring is made of polytetrafluoroethylene material and is wear-resistant.
