[0027] [Example 1]

[0028] The inventor of the present solution has found that in the prior art, commonly used cooling technologies, such as indirect air cooling, water cooling or air conditioning systems, use air conditioning systems to exhaust hot air from the computer room. Although the cost is low and the technology is mature, the heat capacity of air is low and the heat transfer performance is poor. It is usually difficult to effectively cool down when running at high load. Furthermore, existing cooling systems usually discharge a large amount of heat generated by data centers as waste heat, and do not reuse the waste heat, resulting in energy waste. In addition, traditional air conditioning systems consume a lot of electricity, which increases energy consumption while also increasing operating costs, which is not conducive to sustainable development. The embodiments of the present invention provide the following solutions:

[0029] like Figure 1 As shown, an embodiment of the present invention provides a liquid-cooled data center heat dissipation system, including a plurality of server modules 11 placed in a data center computer room 1, the server modules 11 are immersed in a heat dissipation container 12 filled with insulating liquid, and also includes a solar photovoltaic and thermal integrated collector 2, a latent heat storage 3, a sensible heat storage 4, an air source heat pump unit 5, and an absorption refrigeration unit 6. The solar photovoltaic and thermal integrated collector 2 is respectively connected to the latent heat storage 3 and the sensible heat storage 4 through heat exchange pipes, and the solar photovoltaic and thermal integrated collector 2 is connected to the electrical equipment through a wire. The air source heat pump unit 5 is connected to the latent heat storage 3 through a heat exchange pipe, the absorption refrigeration unit 6 is connected to the sensible heat storage 4 through a heat exchange pipe, the latent heat storage 3 is connected to the sensible heat storage 4 through a heat exchange pipe, and the heat dissipation container 12 is connected to the sensible heat storage 4 through a heat exchange pipe.

[0030] It should be noted that the heat dissipation container 12 can be a container. By using insulating liquid to directly discharge the heat of the server module, it can effectively cope with the heat generated by the high-load computing center. The discharged heat is stored in the latent heat storage 3 and the sensible heat storage 4 through the waste heat recovery device. The solar photovoltaic and thermal integrated collector 2 emits heat while providing electricity to the electrical equipment, and is stored in the latent heat storage 3 and the sensible heat storage 4. The heat stored in the latent heat storage 3 and the sensible heat storage 4 is used to drive the air source heat pump unit 5 and the absorption refrigeration unit 6 to cool the data center room 1. In addition, when the server module 11 is in the high-load operation stage, the heat stored in the sensible heat storage 4 drives the absorption refrigeration unit 6 to cool the data center room 1; when the server module 11 is in the low-load operation stage, the heat stored in the latent heat storage 3 drives the air source heat pump unit 5 to cool the data center room 1. At the same time, it is detected whether the outdoor temperature exceeds the preset threshold. If the outdoor temperature exceeds the preset threshold, the heat stored in the latent heat storage device 3 drives the absorption refrigeration unit 6 to cool the data center room 1 at the same time, thereby ensuring a continuous and stable cooling effect indoors.

[0031] It is understandable that the system fully integrates the waste heat generated by the server module 11 and the solar photovoltaic thermal integrated collector 2, as well as the cooling capacity of the air source heat pump unit 5 and the absorption refrigeration unit 6, reducing dependence on traditional energy, improving the overall energy efficiency of the system, and creating an energy-saving and carbon-reducing data center efficient refrigeration system. Through the combination of the solar photovoltaic thermal integrated collector 2 with the air source heat pump unit 5 and the absorption refrigeration unit 6, a large amount of waste heat generated by the data center server is converted from waste heat into efficient refrigeration power, significantly reducing the refrigeration load of the data center under high load operation and high temperature environment. This system uses the latent heat storage device 3 and the sensible heat storage device 4 to work in parallel, not only realizing multi-level storage of thermal energy, but also driving the absorption refrigeration unit 6 through thermal energy during high temperature periods, optimizing the working efficiency of the air source heat pump unit 5, ensuring that the refrigeration system can still operate efficiently when the external temperature is high, ensuring the stable operation of the data center and reducing overall energy consumption.

[0032] In some embodiments, the heat exchange pipelines of the solar photovoltaic and thermal integrated collector 2, the latent heat storage device 3, the sensible heat storage device 4, the air source heat pump unit 5, and the absorption refrigeration unit 6 are all wrapped with thermal insulation materials to reduce heat loss.

[0033] In some embodiments, the server module 11 is displayed in the form of a container, and the liquid inside the container is anti-conductive, highly thermally conductive and corrosion-resistant.

[0034] In some embodiments, the heat storage material in the latent heat storage device 3 includes but is not limited to phase change materials, metals, and molten salts, etc., which are used to make up for the intermittent deficiency of solar energy and assist the refrigeration of the air source heat pump unit.

[0035] In some embodiments, a water level sensor is provided inside the sensible heat storage tank 4, and the water level is judged to determine whether to replenish the water from the outside.

[0036] In some embodiments, the solar photovoltaic and thermal integrated collector 2 includes a photovoltaic cell 21, a heat absorbing medium 22, a controller 23, a battery 24, and an inverter 25. The heat absorbing medium 22 is respectively connected to the two ends of the heat exchange coils of the latent heat storage 3 and the sensible heat storage 4 through a heat exchange pipeline. The photovoltaic cell 21 is connected to the controller 23, and the battery 24 is connected to the photovoltaic cell 24. The input end of the inverter 25 is connected to the battery 24, and the output end of the inverter 25 is connected to the electrical equipment.

[0037] It should be noted that the photovoltaic cell 21 charges the storage battery 24 after sending a control signal through the controller 23, and the storage battery 24 outputs 220V through the inverter 25 to supply power to the electrical equipment, which can be the electrical equipment in the data center room 1 or the electrical equipment in the office adjacent to the data center room 1. The heat absorbing medium 22 is collected through the heat exchange pipeline and stored in the latent heat storage 3 and the sensible heat storage 4, and the heat exchange medium circulating inside can be water, heat transfer oil or nanofluid.

[0038] It can be understood that the system makes full use of clean solar energy to generate high-temperature heat and green electricity. On the one hand, it combines the recovered heat of the server module 11 to meet the cascade utilization of energy and assists the air source heat pump unit 5 to improve the cooling efficiency. On the other hand, it generates green electricity to assist the power demand of the data center and the refrigeration system, which can not only achieve the goal of maximizing energy utilization efficiency, but also promote energy conservation and carbon reduction in the data center.

[0039] In some embodiments, a first heat exchange pump 26 , a first valve 27 and a second valve 28 are provided in the heat exchange pipeline connecting the heat absorbing medium 22 with the latent heat storage device 3 and the sensible heat storage device 4 .

[0040] It should be noted that when the first valve 27 is opened, the heat generated by the solar photovoltaic integrated thermal collector 2 is transported to the latent heat storage 3 for storage through the first heat exchange pump 26. When the second valve 28 is opened, the heat generated by the solar photovoltaic integrated thermal collector 2 is transported to the sensible heat storage 4 for storage through the first heat exchange pump 26. By adjusting the first valve 27 and the second valve 28, a large amount of heat that is temporarily unused in the sensible heat storage 4 can be transferred to the latent heat storage 3 for storage.

[0041] In some embodiments, the air source heat pump unit 5 includes a first condenser 51 and a first evaporator 52. The first evaporator 52 is connected to both ends of the heat exchange coil of the latent heat storage device 3 through a heat exchange pipeline, and the first condenser 51 is connected to a fan coil 53 leading to the data center room 1 through a pipeline. The first evaporator 52 is connected to the first condenser 51 through a condensation pipeline, and a compressor 54 and a third valve 55 are provided in the condensation pipeline.

[0042] It should be noted that the refrigerant evaporates in the first evaporator 52 in the air source heat pump unit 5, absorbs the heat of the air, and then enters the compressor 54 and the first condenser 51 to complete the refrigeration process, and cools the data center room 1 through the fan coil 53.

[0043] In some embodiments, a second heat exchange pump 56 and a fourth valve 57 are provided in the heat exchange pipe connecting the first evaporator 52 and the latent heat storage 3 .

[0044] It should be noted that when the fourth valve 57 is opened, heat is transported to the air source heat pump unit 5 through the second heat exchange pump 56 to drive the air source heat pump unit 5 .

[0045] In some embodiments, the absorption refrigeration unit 6 includes a second evaporator 61, an absorber 62 and a second condenser 63. The second evaporator 63 is connected to both ends of the heat exchange coil of the sensible heat storage device 4 through a heat exchange pipeline. The second evaporator 61, the absorber 62 and the second condenser 63 are connected in sequence through pipelines. The second condenser 63 is connected to a floor air supply duct 64 leading to the data center computer room 1 through a pipeline.

[0046] It should be noted that during the refrigeration process of the absorption refrigeration unit 6, the second evaporator 61 absorbs heat to generate cold air. After the refrigerant evaporates, it is absorbed by the absorbent in the absorber 62, and then enters the second condenser 63 to complete the refrigeration process, and then cools the data center room 1 through the floor air supply duct 64.

[0047] In some embodiments, a third heat exchange pump 65 and a fifth valve 66 are provided in the heat exchange pipe connecting the second evaporator 61 and the sensible heat storage 4 .

[0048] It should be noted that when the fifth valve 66 is opened, heat is transported to the absorption refrigeration unit 6 through the third heat exchange pump 65 to drive the absorption refrigeration unit 6 .

[0049] In some embodiments, a fourth heat exchange pump 121 and a sixth valve 122 are provided in the heat exchange pipe connecting the heat dissipation container 12 and the sensible heat storage device 4 .

[0050] It should be noted that when the sixth valve 122 is opened, the heat is transported to the sensible heat storage device 4 through the fourth heat exchange pump 121 , and the heat is stored in the sensible heat storage device 4 .

[0051] In some embodiments, the sensible heat storage device 4 is connected to the water terminal 7 through a water pipe. A filter 8 is provided on the water pipe. The filter 8 is used for filtering and disinfecting so that the water can be used as daily water.

[0052] [Example 2]

[0053] like Figure 2 As shown, an embodiment of the present invention further provides a liquid-cooled data center heat dissipation method, including the liquid-cooled data center heat dissipation system in embodiment 1, and the method includes:

[0054] Step 101 , immersing the server module 11 in a heat dissipation container 12 filled with insulating liquid, and storing the heat generated by the heat dissipation container in the sensible heat storage device 4 .

[0055] Step 102, supply electricity to the electrical equipment through the solar photovoltaic and thermal integrated collector 2, and store the heat generated by the power supply in the latent heat storage 3 and the sensible heat storage 4 respectively.

[0056] It should be noted that the photovoltaic cell 21 in the solar photovoltaic and thermal integrated collector 2 charges the storage battery 24 after the controller 23 sends a control signal, and the storage battery 24 outputs 220V through the inverter 25 to supply power to the electrical equipment, which can be the electrical equipment in the data center room 1 or the electrical equipment in the office adjacent to the data center room 1. The heat absorbing medium 22 is collected through the heat exchange pipeline and stored in the latent heat storage 3 and the sensible heat storage 4, and the heat exchange medium circulating inside can be water, heat transfer oil or nanofluid.

[0057] Step 103: When the server module 11 is in the high-load operation stage, the heat stored in the sensible heat storage device 4 drives the absorption refrigeration unit 6 to cool the data center room 1.

[0058] It should be noted that during the refrigeration process of the absorption refrigeration unit 6, the second evaporator 61 absorbs heat to generate cold air. After the refrigerant evaporates, it is absorbed by the absorbent in the absorber 62, and then enters the second condenser 63 to complete the refrigeration process, and then cools the data center room 1 through the floor air supply duct 64.

[0059] Step 104, when the server module 11 is in the low-load operation stage, the heat stored in the latent heat storage device 3 drives the air source heat pump unit 5 to cool the data center room 1; detects whether the outdoor temperature exceeds the preset threshold. If the outdoor temperature exceeds the preset threshold, the heat stored in the latent heat storage device 3 drives the absorption refrigeration unit 6 to cool the data center room 11 at the same time.

[0060] It should be noted that when the outside ambient temperature is too high in summer, the outdoor air temperature is high, and the cooling efficiency of the air source heat pump unit 5 is easily affected. Therefore, the system requires the latent heat storage device 3 to provide auxiliary support to maintain a stable cooling effect. At this time, the heat stored in the latent heat storage device 3 can be used to drive the absorption refrigeration unit 6. The cold energy generated by the absorption refrigeration unit 6 through the lithium bromide or ammonia-water cycle can be transported through the heat exchange pipeline and work in parallel with the air source heat pump unit 5, thereby reducing the working pressure of the air source heat pump unit 5 alone at high temperatures. With the assistance of the latent heat storage device 3, the system can effectively deal with the problem of decreased efficiency of the air source heat pump unit 5 when the outside temperature is high, and ensure a continuous and stable indoor cooling effect.

[0061] In summary, embodiments 1-2 of the present invention provide a liquid-cooled data center heat dissipation system and method, which directly removes and stores the heat of the server module by using insulating liquid, provides electricity and stores the dissipated heat by using solar photovoltaics, and then stores heat by using latent heat storage devices and sensible heat storage devices to flexibly drive air source heat pump units and absorption refrigeration units for cooling, thereby greatly improving the cooling effect when the server is running at high load, reducing power consumption and operating costs, achieving efficient reuse of thermal energy, and reducing dependence on traditional energy sources.
