Description

Technical Field

[0001] This invention belongs to the field of chip cooling technology, specifically, it relates to a modular immersion cooling device with isolation and recovery functions. Background Technology

[0002] Immersion liquid cooling technology, especially two-phase immersion cooling, has become a key technology for cooling high-performance computing chips due to its extremely high heat dissipation efficiency. In this technology, electronic components are directly immersed in a low-boiling-point fluorinated liquid, and a large amount of heat is carried away by the boiling of the liquid. However, existing immersion cooling systems, whether using simple cooling towers or traditional chiller units, ultimately release a large amount of low-grade heat energy generated by the chips directly into the atmosphere. This not only causes huge energy waste but also contradicts the global "dual-carbon" goals, especially in northern winters, where data centers consume electricity and emit heat while building heating requires large amounts of gas or electricity, creating a huge contradiction in energy utilization.

[0003] To achieve lower boiling temperatures, existing technologies typically place the entire cooling chamber under negative pressure. However, maintaining high negative pressure places extreme demands on the chamber's sealing. During long-term operation, factors such as aging of sealing materials and vibration can easily lead to the intrusion of external air and moisture into the chamber. Air intrusion forms non-condensable gases, creating an insulating layer on the heat exchange surface and severely degrading heat dissipation efficiency; moisture intrusion reacts with the fluorinated liquid, generating acidic substances that corrode components and cause coolant deterioration. Although existing technologies employ purification devices such as vacuum pumps and molecular sieves to remove intruding air and moisture, this is a "post-hoc" measure, increasing system complexity and energy consumption, and failing to fundamentally solve the pollution problem caused by initial intrusion. With the development of technologies such as artificial intelligence and high-performance computing, the power density and total power consumption of computing centers are rising sharply, and traditional air-cooling and single-phase immersion technologies are approaching their limits.

[0004] While two-phase immersion cooling technology can effectively solve the problem of heat dissipation in high heat flux density environments, it faces challenges in its promotion to large-scale computing centers: 1. System bloat and lack of scalability: Existing solutions often treat the entire rack or multiple racks as a single large cooling chamber. This system is bulky, difficult to expand, and once deployed, it is difficult to adjust flexibly according to computing power requirements.

[0005] 2. Concentrated reliability risks: Large cavities have numerous sealing surfaces and interfaces. Failure at any node could lead to contamination of the fluorinated fluid in the entire system, causing large-scale business interruptions, resulting in highly concentrated risks.

[0006] 3. Difficult to maintain: When a single server node fails and needs repair, it may require complex operations such as draining and repressurizing the entire large cooling system, resulting in a long maintenance window and complex operations.

[0007] 4. Difficulty in optimizing energy efficiency: Each large cavity requires a complex pressure control and condensation system, which leads to a bottleneck in optimizing the overall energy efficiency (PUE) of the system.

[0008] Therefore, a system architecture is needed that retains the high performance of immersion cooling while meeting the modularity, scalability, and high reliability requirements of data centers. There is an urgent need in this field for an immersion cooling solution that can fundamentally prevent air intrusion, prevent leaks, and employ multiple measures to ensure foolproof performance, while also maintaining high heat dissipation. However, even with a modular design, how to quickly and safely handle the expensive and pure fluorinated liquid inside a module when a leak occurs and repair or replacement is needed presents a new challenge. Traditional manual pumping methods are cumbersome, time-consuming, and carry the risk of secondary contamination and loss of the working fluid. This, to some extent, offsets the maintenance convenience brought by modularity.

[0009] In view of this, the present invention is proposed. Summary of the Invention

By setting up a positive pressure chamber, it physically isolates moisture in the air, preventing it from entering the negative pressure chamber and hydrolyzing and corroding the sealing gasket with fluorinated liquid, thus extending the service life of the sealing gasket in the negative pressure chamber. By modularizing components such as the outer shell, individual modules can be repaired or replaced in case of failure without affecting the normal operation of other modules. The generated heat can be transferred to the heat-using terminal after being transported by the chiller, achieving efficient energy utilization.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0025] Example 1:

[0026] like Figures 1 to 4 As shown, a modular immersion cooling device with isolation and recovery functions includes an inner shell 102, an electronic component 104 is disposed inside the inner shell 102, and a positive pressure protection mechanism. The positive pressure protection mechanism includes an outer shell 100, with the inner shell 102 placed inside the outer shell 100. The positive pressure protection mechanism also includes a first sealing component and a second sealing component. The first sealing component is used to seal the outer shell 100, and the second sealing component is used to seal the inner shell 102. A positive pressure cavity is formed between the outer shell 100 and the inner shell 102, and the pressure of the positive pressure cavity is greater than the standard atmospheric pressure. A negative pressure cavity is formed inside the inner shell 102, and the pressure of the negative pressure cavity is less than the standard atmospheric pressure.

[0027] like Figure 3 As shown, in a specific embodiment, the first sealing assembly includes a first sealing cover 101, and the second sealing assembly includes a second sealing cover 103. The first sealing cover 101 is adapted to the outer shell 100, and the second sealing cover 103 is adapted to the inner shell 102. An inflation pipe 111 is installed on one side of the outer shell 100. In this configuration, the inner shell 102 is filled with fluorinated liquid, and the inflation pipe 111 is used to fill the space between the outer shell 100 and the inner shell 102 with fluorinated liquid vaporized fluid. Using fluorinated liquid vaporized fluid reduces pollution when leaking into the external environment and avoids pollution to the negative pressure chamber. The inner shell 102 and the side wall of the outer shell 100 are respectively equipped with a first sealing element 109 and a second sealing element 110 for sealing the cable.

[0028] like Figures 3 to 4As shown, further, a draining mechanism is provided at the bottom of the outer shell 100. The draining mechanism includes a storage tank 117. A drain pipe 112 is installed between the storage tank 117 and the inner shell 102. A first electronic valve 113 and a second electronic valve 114 are installed on the drain pipe 112. A circulation pipe 115 is installed between the first electronic valve 113 and the second electronic valve 114 on the drain pipe 112. One end of the circulation pipe 115 is connected to the storage tank 117. A circulation pump 116 is installed on the circulation pipe 115. In this configuration, when draining, the first electronic valve 113 and the second electronic valve 114 are opened to allow the fluorinated liquid in the negative pressure chamber to enter the drain pipe 112. When transporting the fluorinated liquid, the first electronic valve 113 is opened and the second electronic valve 114 is closed. The circulation pump 116 transports the fluorinated liquid in the storage tank 117 to the negative pressure chamber through the circulation pipe 115 and the drain pipe 112, while the second electronic valve 114 remains closed so that the fluorinated liquid can no longer flow into the storage tank 117.

[0029] like Figures 1 to 2 As shown, a vacuum tube 105 is further installed on one side of the top of the inner shell 102. One end of the vacuum tube 105 passes through the outer shell 100 and is connected to a vacuum pump 106. The vacuum tube 105 and the outer shell 100 are sealed together. A valve is installed on the vacuum tube 105 to seal the vacuum tube 105 after vacuuming, so as to prevent external gas from entering the negative pressure chamber through the vacuum tube 105. A heat dissipation mechanism is provided on one side of the outer casing 100. The heat dissipation mechanism includes a heat dissipation copper pipe 118 installed inside the inner casing 102. Both ends of the heat dissipation copper pipe 118 pass through the inner casing 102 and the outer casing 100 and are connected to a refrigerator 108. The refrigerator 108 includes an evaporator 107, and the heat dissipation copper pipe 118 is connected to the evaporator 107. In this configuration, the refrigerator 108 can be connected to a heat-using terminal. After heat exchange with the evaporator 107, the heat from the heat dissipation copper pipe 118 is transported by the refrigerator 108 to the heat-using terminal to meet the heat demand and achieve efficient energy utilization.

[0030] In this embodiment, the outer casing 100 and its internal structure are a module, and multiple modules are arranged in parallel. When a single module fails, it does not affect the operation of other modules. Furthermore, the vacuum tube 105 and the drain pipe 112 of each module are set separately and connected by quick-connect connectors, which can realize the function of quickly replacing a single module.

[0031] The implementation principle of a modular immersion cooling device with isolation and recovery functions in this embodiment is as follows: During operation, the positive pressure chamber maintains a positive pressure state, and the negative pressure chamber maintains a negative pressure state. The fluorinated liquid in the inner shell 102 maintains a lower boiling point in the negative pressure environment. When the electronic component 104 is working, the heat emitted causes the fluorinated liquid to vaporize, and the heat is carried away during the vaporization process. After contacting the heat dissipation copper pipe 118, it condenses and liquefies, realizing the circulation of the gas phase and liquid phase of the fluorinated liquid. At the same time, the heat dissipation copper pipe 118 is cooled after exchanging heat with the evaporator 107 of the refrigerator 108, and the heat can be transported to the heat-using terminal through the refrigerator 108 to realize the effective utilization of energy. The fluorinated liquid vaporized fluid filling the positive pressure chamber keeps the positive pressure chamber at a state higher than atmospheric pressure, so that outside air cannot enter the positive pressure chamber, physically isolating the air and preventing it from entering the negative pressure chamber. When the first sealing cover 101 leaks, the fluorinated liquid will not cause pollution to the external environment. When the second sealing cover 103 leaks, the fluorinated liquid entering the negative pressure chamber will also not cause pollution. When electronic component 104 malfunctions and requires emergency repair, disconnect the heat dissipation copper pipe 118 at the corresponding location and open the first electronic valve 113 and the second electronic valve 114. At this time, the fluorinated liquid in the negative pressure chamber enters the storage tank 117 through the drain pipe 112. After emptying, the worker can quickly replace or repair it. After completion, start the vacuum pump 106 and draw a vacuum in the negative pressure chamber through the vacuum tube 105. After reaching a certain vacuum level, open the first electronic valve 113 and close the second electronic valve 114. Start the circulation pump 116. The circulation pump 116 delivers the fluorinated liquid supplied in the storage tank 117 to the negative pressure chamber through the circulation pipe 115.

[0032] Example 2:

[0033] A modular immersion cooling device with isolation and recovery functions, further comprising a control system, the control system including; The fault analysis unit cyclically executes the fault analysis process based on the temperature and pressure changes of the positive and negative pressure chambers, determines the fault type, performs the corresponding fault troubleshooting operation based on the fault type, and re-executes the fault analysis process.

[0034] The fault analysis process includes obtaining the actual pressure change and temperature change values ​​of the positive pressure chamber, and distinguishing the fault type as temperature abnormality or leakage abnormality based on the actual pressure change and temperature change values.

[0035] The types of faults include: The theoretical pressure change of the positive pressure chamber corresponding to the temperature change is calculated based on the ideal gas law, and a pressure change threshold is set. When the positive pressure chamber experiences a temperature change due to heat transfer from the negative pressure chamber, the theoretical pressure change corresponding to the temperature difference can be calculated using the ideal gas law PV=nRT. Here, P is the pressure of the positive pressure chamber, V is the volume of the gas in the positive pressure chamber, which is equal to and remains constant with the volume of the positive pressure chamber, n is the amount of substance of the gas, which remains constant in the absence of leakage in the positive pressure chamber, R is the ideal gas constant, and T is the temperature of the gas. When the difference between the actual pressure change value and the theoretical pressure change value is less than the pressure change threshold, it is judged as a temperature anomaly, indicating that no leakage has occurred in the positive pressure chamber. When the difference between the actual pressure change and the theoretical pressure change is greater than or equal to the pressure change threshold, it is judged as a leakage anomaly, indicating that a leak has occurred in the positive pressure chamber.

[0036] The pressure change threshold is used to reduce the impact of volume changes caused by the liquefaction of fluorinated liquid vaporized fluid due to actual factors such as pressure and temperature. The fluorinated liquid vaporizing fluid in the positive pressure chamber and the fluorinated liquid in the negative pressure chamber can be of different types, so as to maintain the fluorinated liquid in the positive pressure chamber in the gas phase while keeping the fluorinated liquid in the negative pressure chamber in the liquid phase.

[0037] When the fault type is temperature abnormality, it indicates that there is only temperature abnormality and no leakage abnormality. When the fault type is leakage abnormality, it includes leakage abnormality or leakage abnormality and temperature abnormality. When a leakage anomaly occurs, the difference between the actual pressure change and the theoretical pressure change is greater than or equal to the pressure change threshold. The cause of this result may be a leak in the positive pressure chamber, or it may be accompanied by an abnormal temperature. The possibility of an abnormal temperature cannot be directly ruled out.

[0038] Leakage anomalies include positive pressure chamber leakage and negative pressure chamber leakage. Positive pressure chamber leakage indicates leakage of the first sealing cover 101, and negative pressure chamber leakage indicates leakage of the second sealing cover 103. When a temperature anomaly is detected, temperature anomaly regulation is performed based on the root cause analysis results of the fault analysis unit. Temperature anomaly regulation includes adjusting the operating parameters of the heat dissipation mechanism or electronic component 104 to eliminate the temperature anomaly. When a leakage anomaly is detected, the temperature parameter is used to verify whether it is accompanied by a temperature anomaly. If it is, the temperature anomaly adjustment is performed first, and then the root cause analysis of the leakage anomaly is performed to determine the type of leakage anomaly.

[0039] The fault analysis unit also includes acquiring the actual pressure change value of the negative pressure chamber and configuring the pressure fluctuation threshold. When the actual pressure change value is lower than the pressure fluctuation threshold, it indicates that the negative pressure chamber has not leaked, while the positive pressure chamber has leaked. When the actual pressure change value is higher than the pressure fluctuation threshold, it indicates that the negative pressure chamber has leaked. When the negative pressure chamber is not leaking, only the positive pressure chamber needs to be opened for maintenance. When the negative pressure chamber is leaking, since the negative pressure chamber is located inside the positive pressure chamber, the positive pressure chamber needs to be opened for maintenance, so there is no need to confirm whether the positive pressure chamber is leaking.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
