[0031] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0032] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0033] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0034] The utility model provides a refrigeration system, which can be used in a cold plate liquid cooling system of a data center and can perform heat exchange and cooling on a refrigeration terminal, wherein the refrigeration terminal is also a server, which can include chips such as a CPU (central processing unit), a GPU (graphics processing unit), etc.

[0035] like Figures 1 to 3 As shown, the refrigeration system provided by the embodiment of the utility model includes:

[0036] A magnetic levitation compression module 1, a heat dissipation module 2, a power module 3 and a cold storage module 4, wherein one end of the magnetic levitation compression module 1 is connected to the outlet of the refrigeration terminal, the other end of the magnetic levitation compression module 1 is connected to the inlet of the heat dissipation module 2, and the outlet of the heat dissipation module 2 is connected to the inlet of the power module 3;

[0037] The power module 3 includes two outlets, one outlet pipeline of the power module 3 is connected to the inlet of the refrigeration end, and cools the refrigeration end, the other outlet pipeline of the power module 3 is connected to one end of the cold storage module 4, and the other end pipeline of the cold storage module 4 is connected to the outlet of the refrigeration end, and refrigerant flows in the pipeline of the refrigeration system, and low-temperature water is stored in the cold storage module 4.

[0038] The utility model provides an efficient and stable refrigeration system, which mainly comprises a magnetic suspension compression module 1, a heat dissipation module 2, a power module 3 and a cold storage module 4.

[0039] Among them, the magnetic levitation compression module 1 is the core component of the refrigeration system. The inlet of the magnetic levitation compression module 1 is connected to the outlet of the refrigeration terminal through a pipeline, and the outlet pipeline of the magnetic levitation compression module 1 is connected to the inlet of the heat dissipation module 2, so that the magnetic levitation compression module 1 can transfer the heat generated during its compression process to the heat dissipation module 2. The magnetic levitation compression module 1 uses magnetic levitation technology to achieve high-speed and stable operation of the compressor, thereby reducing the friction loss during the operation of the compressor and improving the compression efficiency of the magnetic levitation compression module 1. In addition, the module operates stably, has low noise, and has little interference with the surrounding environment.

[0040] After the heat dissipation module 2 receives the heat from the magnetic suspension compression module 1, the heat can be quickly discharged from the system through the outdoor fan 22, thereby ensuring the stable operation of the refrigeration system. The outlet pipeline of the heat dissipation module 2 is connected to the inlet of the power module 3, so that the heat dissipation module 2 can transport the refrigerant after heat exchange and cooling to the power module 3.

[0041] like Figures 1 to 3 As shown, the power module 3 is a circulating drive device for the refrigerant, which includes two outlets. One of the outlet pipes is connected to the inlet of the refrigeration terminal, and the refrigerant is circulated to cool the refrigeration terminal. The other outlet is connected to the inlet of the cold storage module 4 by a pipe, so that the refrigerant can be transported to the cold storage module 4 for cold storage, so that the cold stored in the cold storage module 4 can be used for refrigeration when the power is off, thereby achieving continuous refrigeration.

[0042] Specifically, low-temperature water is stored in the cold storage module 4. When the load of the refrigeration terminal is low or the refrigeration terminal does not need refrigeration, the cold storage module 4 can absorb the coldness in the refrigerant from the power module 3, further cool the low-temperature water and store it. When the refrigeration system is powered off, the cold storage module 4 can release the stored coldness and connect to the outlet of the refrigeration terminal through a pipeline to achieve cooling of the refrigeration terminal, thereby balancing the refrigeration demand of the refrigeration system and ensuring the refrigeration continuity of the refrigeration system.

[0043] Among them, in the pipeline of the entire refrigeration system, the refrigerant can circulate in the pipeline, thereby achieving continuity and stability of the refrigeration effect. In addition, the operating status of each module can be adjusted according to the actual refrigeration demand to achieve optimized operation of the system.

[0044] Optionally, the cold storage module 4 includes a cold storage tank 41 , and low-temperature water is stored in the cold storage tank 41 .

[0045] like Figures 1 to 3As shown, the introduction of the cold storage tank 41 enables the refrigeration system to better manage the cold. When the load at the refrigeration terminal is low or the refrigeration terminal does not need refrigeration, the refrigeration system can cool the low-temperature water through the power module 3 and store it in the cold storage tank 41. When the refrigeration system is powered off, the refrigeration system can use the cold stored in the cold storage tank 41 for refrigeration, thereby reducing the refrigeration system's dependence on the power grid and ensuring the refrigeration continuity of the refrigeration system.

[0046] In addition, the design of the cold storage tank 41 also makes the refrigeration system more flexible and expandable. According to the actual refrigeration demand of the refrigeration terminal, the capacity and number of the cold storage tank 41 can be adjusted to meet the refrigeration needs of different occasions and scales. In addition, the cold storage tank 41 can also be integrated with other refrigeration equipment or systems to form a more complex and efficient refrigeration solution.

[0047] Optionally, the cold storage module 4 further includes a first valve, and the first valve is used to control the working state of the cold storage module 4.

[0048] Specifically, by setting the first valve, the working state of the cold storage module 4 can be accurately controlled. When the load at the refrigeration end is high, the first valve can be closed, and the cold storage module 4 does not work at this time, and the refrigeration system performs a normal refrigeration mode, such as Figure 1 When the refrigeration terminal load is low or the refrigeration terminal does not need refrigeration, or the refrigeration system is powered off, the first valve can be opened. At this time, the refrigeration system can cool the low-temperature water through the power module 3 and store it in the cold storage module 4, as shown. Figure 2 As shown, or the cold storage module 4 can release the stored cold and achieve auxiliary refrigeration, such as Figure 3 This precise control can ensure that the cold storage module 4 can play the maximum role at the right time and improve the overall performance of the refrigeration system.

[0049] In addition, the first valve can be used to quickly switch the working state of the cold storage module 4, so that the refrigeration system can respond quickly when faced with emergencies or failures. For example, when the refrigeration system is powered off and natural cooling is insufficient, the first valve can be quickly opened to quickly release the cold stored in the cold storage module 4 to cope with the increase in refrigeration demand at the refrigeration terminal. This rapid response capability helps to improve the stability and reliability of system operation and reduce the risks caused by refrigeration interruption.

[0050] Optionally, the cold storage module 4 includes a first working state and a second working state. When the cold storage module 4 is in the first working state, the first valve is opened, and the refrigerant flowing out of the power module 3 flows to the magnetic suspension compression module 1 after being stored in the cold storage tank 41;

[0051] When the cold storage module 4 is in the second working state, the first valve is opened, and the refrigerant flowing out of the outlet of the refrigeration terminal is cooled by the cold storage tank 41 and then flows to the power module 3 .

[0052] like Figure 2 As shown, when the cold storage module 4 is in the first working state, the first valve is opened, and the refrigerant flowing out of the power module 3 is stored in the cold storage tank 41, and then flows to the magnetic suspension compression module 1 for compression. At this time, the cold storage module 4 is in the cold storage state. Such a design can store the cold amount of the refrigerant during the circulation process, thereby improving the utilization efficiency of the refrigerant.

[0053] like Figure 3 As shown, when the cold storage module 4 is in the second working state, the high-temperature gaseous refrigerant flowing out of the outlet of the refrigeration terminal can be cooled through the cold storage tank 41, and the cooled low-temperature liquid refrigerant flows to the refrigeration terminal for refrigeration after passing through the power module 3. At this time, the cold storage module 4 is in a cooling state. In this process, the low-temperature water in the cold storage tank 41 can effectively cool the refrigerant flowing through, thereby enhancing the refrigeration effect of the refrigerant.

[0054] Optionally, the cold storage module 4 further includes a third working state, and when the cold storage module 4 is in the third working state, the first valve is closed.

[0055] like Figure 1 As shown, when the cold storage module 4 is in the third working state, the first valve is closed to stop the cold storage module 4 from working, and the direct exchange between the cold storage module 4 and the refrigerant is also stopped, thereby avoiding unnecessary energy loss. This design allows the refrigeration system to close the cold storage module 4 in time when the refrigeration end load is high, thereby reducing energy consumption and improving the overall energy efficiency of the refrigeration system.

[0056] In addition, after closing the first valve, the circulation path between the cold storage module 4 and the refrigerant is cut off, which also helps prevent the refrigerant from leaking or mixing with impurities, thereby improving the safety of the refrigeration system. Moreover, the third working state also provides convenience for the maintenance and repair of the refrigeration system. When the cold storage module 4 needs to be repaired or replaced, it can be adjusted to the third working state, which can ensure the safety and convenience of the repair process.

[0057] Optionally, the magnetic levitation compression module 1 includes a magnetic levitation compressor 11 and a second valve 12 , the pipeline of the magnetic levitation compressor 11 is connected between the outlet of the refrigeration end and the inlet of the heat dissipation module 2 , and the second valve 12 is connected in parallel to both ends of the magnetic levitation compressor 11 .

[0058] like Figures 1 to 3As shown, the magnetic levitation compressor 11, as the core component of the refrigeration system, can achieve high-speed and stable operation by using magnetic levitation technology, significantly reducing friction loss during operation and improving the compression efficiency of the magnetic levitation compressor 11. This efficient and stable operation mode not only improves the overall performance of the refrigeration system, but also reduces energy consumption and achieves energy-saving effects.

[0059] In addition, the introduction of the second valve 12 also provides additional protection and fault response mechanism for the refrigeration system. When the magnetic levitation compressor 11 fails or needs maintenance, the second valve 12 can be opened to short-circuit the magnetic levitation compressor 11 to isolate it from the system without affecting the normal operation of the entire refrigeration system, thereby improving the reliability and stability of the refrigeration system.

[0060] Optionally, the magnetic levitation compression module 1 further includes an air intake filter, and the air intake filter is arranged on a side of the magnetic levitation compressor 11 away from the heat dissipation module 2 .

[0061] Specifically, the setting of the air intake filter can filter impurities and particulate matter entering the magnetic levitation compressor 11, thereby protecting the operating parts of the magnetic levitation compressor 11 from wear and damage, helping to extend the service life of the magnetic levitation compressor 11, and also improving the stability and reliability of the entire refrigeration system.

[0062] In addition, if impurities and particulate matter enter the magnetic levitation compressor 11, they may adhere to the internal surface of the magnetic levitation compressor 11, affecting the flow and heat transfer effect of the refrigerant, thereby reducing the refrigeration efficiency. The use of the air intake filter can effectively reduce the occurrence of this situation, keep the refrigerant pure and flow smoothly, thereby improving the refrigeration efficiency and reducing the energy consumption of the refrigeration system.

[0063] Optionally, the heat dissipation module 2 includes a condenser 21 and an outdoor fan 22, the condenser 21 pipeline is connected between the magnetic levitation compression module 1 and the power module 3, the outdoor fan 22 is opposite to the condenser 21, and the outdoor fan 22 is used for heat exchange with the external environment.

[0064] like Figures 1 to 3 As shown, the condenser 21, as the core component of the heat dissipation module 2, is connected between the magnetic levitation compression module 1 and the power module 3 through a pipeline, and can effectively condense the high-temperature and high-pressure refrigerant gas discharged from the magnetic levitation compression module 1 into liquid. The outdoor fan 22 is opposite to the condenser 21, and can quickly take away the heat generated by the condenser 21 and dissipate it to the external environment through strong convection. This efficient heat dissipation mechanism ensures that the refrigeration system can still operate stably in a high-temperature environment, avoiding performance degradation or failure due to overheating.

[0065] Among them, the introduction of the outdoor fan 22 significantly enhances the heat exchange efficiency between the condenser 21 and the external environment. By adjusting the speed and wind direction of the outdoor fan 22, the heat dissipation of the condenser 21 can be controlled, thereby optimizing the energy consumption of the refrigeration system. When the refrigeration demand is low, the speed of the outdoor fan 22 can be reduced to reduce the heat dissipation and save energy; when the refrigeration demand is at a peak, the speed of the outdoor fan 22 can be increased to ensure the heat dissipation effect of the condenser 21 and meet the refrigeration demand.

[0066] Optionally, the power module 3 includes a liquid storage tank 31 and a refrigerant pump 32, the liquid storage tank 31 pipeline is connected between the heat dissipation module 2 and the cold storage module 4, the liquid storage tank 31 stores refrigerant, and the refrigerant pump 32 is connected between the cold storage module 4 and the inlet of the refrigeration terminal.

[0067] like Figures 1 to 3 As shown, the liquid storage tank 31 serves as a storage and buffer device for the refrigerant, which can ensure a stable supply of refrigerant in the refrigeration system. During the refrigeration cycle, a certain amount of refrigerant is stored in the liquid storage tank 31, and can be released in time when needed, thereby avoiding the degradation of the refrigeration system performance caused by insufficient or fluctuating refrigerant supply. This stable refrigerant supply helps to improve the overall performance of the refrigeration system and ensure that it can operate efficiently under various working conditions.

[0068] In addition, by connecting the refrigerant pump 32 between the cold storage module 4 and the inlet of the refrigeration terminal, the refrigerant flow rate can be flexibly adjusted. According to the refrigeration demand and the system operation status, the speed and output pressure of the refrigerant pump 32 can be adjusted in time to change the circulation speed and flow rate of the refrigerant. This flexible adjustment method enables the refrigeration system to better adapt to the refrigeration needs of different occasions and scales, and also improves the flexibility and adaptability of the system.

[0069] In addition, the power module 3 may also include a fluorine pump 33, which is connected between the outlet of the heat dissipation module 2 and the inlet of the refrigeration terminal. In the refrigeration mode of the fluorine pump 33, the magnetic suspension compression module 1 can be stopped, that is, the natural cold source is fully utilized, and the energy efficiency ratio is greatly improved.

[0070] Optionally, it also includes a first electric valve 5 and a second electric valve 6, the first electric valve 5 is arranged on the side of the magnetic levitation compression module 1 away from the heat dissipation module 2, and the second electric valve 6 is arranged on the side of the power module 3 away from the heat dissipation module 2, and the first electric valve 5 and the second electric valve 6 are respectively used to adjust the amount of refrigerant flowing through.

[0071] like Figures 1 to 3As shown, by introducing the first electric valve 5 and the second electric valve 6, accurate control of the refrigerant flow rate can be achieved. According to the refrigeration demand and the system operation status, the opening of the first electric valve 5 and the second electric valve 6 can be adjusted in time to change the flow path and flow rate of the refrigerant in the refrigeration system. This precise control allows the refrigerant to be more evenly distributed to each component, improves the refrigeration effect, and avoids performance degradation caused by uneven distribution of the refrigerant.

[0072] In addition, by adjusting the opening of the first electric valve 5 and the second electric valve 6, the circulation path and flow of the refrigerant can be optimized to reduce unnecessary energy loss. When the cooling demand is low, the opening of the two electric valves can be appropriately reduced to reduce the circulation of the refrigerant and reduce the energy consumption of the system; when the cooling demand is peak, the opening of the two electric valves can be increased to ensure sufficient supply of refrigerant to meet the cooling demand. This flexible adjustment method helps to improve the energy efficiency ratio of the refrigeration system and reduce overall energy consumption.

[0073] The utility model also provides a data center, comprising the above-mentioned refrigeration system.

[0074] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment.
