Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] During the operation of the data center computer room, a large amount of waste heat is generated. This heat is mainly eliminated by the computer room air conditioner, resulting in a large air conditioning load and energy waste.

[0032] A plant factory is an industrialized agricultural system for producing plant products. Plant products require photosynthesis during their growth. However, in the low room temperature environment in winter, the photosynthesis of plant products is weakened, affecting their growth.

[0033] In order to ensure the normal growth of plant products in winter, plant factories need to adopt heating measures such as heating lamps, independent air conditioners and stoves in winter. These measures increase the cost of plant factories and are not conducive to the implementation of energy conservation and emission reduction.

[0034] Therefore, how to utilize the waste heat of the data center room for the winter heat supply of the plant factory is a technical problem that needs to be solved urgently by those skilled in the art.

[0035] The plant factory heat supply system based on waste heat recovery from a data center computer room provided in an embodiment of the present invention, by arranging a heat transfer device between the data center computer room and the plant factory, and utilizing the heat transfer medium in the heat transfer device to transfer the heat absorbed by the evaporation unit of the heat transfer device along the heat transfer channel to the condensation unit of the heat transfer device for heat release, thereby realizing the use of the heat of the data center computer room for heat supply to the plant factory in winter. Compared with the existing data center computer room in which most of the waste heat is directly discharged into the atmosphere and the plant factory is heated by heating lamps, independent air conditioners and stoves in winter, on the one hand, it reduces the operating cost of the data center computer room and converts waste heat into "negative carbon"; on the other hand, it can also promote the growth of plants in the plant factory and improve the yield and quality of agricultural products.

[0036] like Figure 1 As shown, some embodiments of the present invention provide a plant factory heat supply system based on the recovery of waste heat from a data center computer room, in which the waste heat from the data center computer room 1 is used to supply heat to the plant factory 2 in winter, thereby promoting plant growth in the plant factory 2 and improving the yield and quality of agricultural products. At the same time, it can also effectively solve the current problem of waste heat recovery from the data center computer room 1. Compared with my country's data center computer room 1, where most of the waste heat is directly discharged into the atmosphere, which is a huge waste, the plant factory 2 uses heating lamps, independent air conditioners, and stoves to heat up in winter, which not only increases costs but also increases carbon emissions. Based on the use of waste heat from the data center computer room 1 for the supply of heat to the plant factory 2 in winter, the construction of a green data center computer room 1 and a green plant factory 2 can be promoted.

[0037] In order to achieve the above-mentioned use of waste heat from the data center room 1 for supplying heat to the plant factory 2 in winter, effectively transform "waste heat" into "negative carbon" and promote the growth of plants in the plant factory 2, some embodiments of the present invention provide a plant factory heat supply system based on recovering waste heat from the data center room, including a data center room 1, a plant factory 2 and a heat transfer device 3. The data center room 1 can generate heat, the plant factory 2 can consume heat, and the heat transfer between the data center room 1 and the plant factory 2 is achieved through the heat transfer device 3.

[0038] The heat transfer device 3 has an evaporation unit and a condensation unit. The evaporation unit can absorb heat, and the condensation unit can release heat. The evaporation unit and the condensation unit are connected through a heat transfer channel 31. A heat transfer medium is provided in the heat transfer channel 31. The heat transfer medium can transfer the heat absorbed by the evaporation unit along the heat transfer channel 31 to the condensation unit for heat release. Therefore, the evaporation unit is arranged in the data center computer room 1, and the condensation unit is arranged in the plant factory 2.

[0039] The evaporation unit can be arranged in the heat dissipation channel of the data center room 1, or can be arranged to achieve heat exchange with the cooling fan of the data center room 1, so that the evaporation unit can absorb the heat generated by the data center room 1. Similarly, the condensation unit can be arranged in the heating channel of the plant factory 2, or can be arranged to achieve heat exchange with the heating fan of the plant factory 2, so that the condensation unit can release heat to heat the air environment of the plant factory 2.

[0040] Specifically, the heat transfer device 3 can be set as a heat pipe device, one end of the heat pipe device is the evaporation end, and the other end is the condensation end. The evaporation end of the heat pipe device forms an evaporation unit, and the condensation end of the heat pipe device forms a condensation unit. The heat pipe device uses the phase change process of the heat transfer medium evaporating at the evaporation end and condensing at the condensation end (that is, using the evaporation heat absorption and condensation heat release of the heat transfer medium) to quickly conduct heat. The inside of the heat pipe device is in a negative pressure state, and is filled with a suitable heat transfer medium. The heat transfer medium can be selected from supercritical fluids or liquids, such as water, methanol, etc. These heat transfer mediums have low boiling points and are easy to volatilize. The tube wall of the heat pipe device has a liquid wick, which is composed of a capillary porous material. When the evaporation end is heated, the heat transfer medium vaporizes rapidly, and the vapor flows to the condensation end under the power of heat diffusion, and releases heat at the condensation end. The heat transfer medium condenses into liquid again and flows back to the evaporation end along the porous material by capillary action. This cycle continues, and heat can be transmitted continuously.

[0041] The heat transfer channel 31 can also be set as an inner and outer sleeve structure, in which one pipe is a steam channel and the other pipe is a liquid channel to achieve cyclic heat transfer, or a groove structure is opened in the circumferential direction of the inner wall of the heat transfer channel 31 to form a liquid channel for the heat transfer medium that is re-condensed into liquid to reflux and continue heat transfer.

[0042] In this embodiment, a heat transfer device 3 is provided between the data center room 1 and the plant factory 2, and the heat transfer medium in the heat transfer device 3 is used to transfer the heat absorbed by the evaporation unit of the heat transfer device 3 along the heat transfer channel 31 to the condensation unit of the heat transfer device 3 for heat release, thereby realizing the use of the heat of the data center room 1 for supplying heat to the plant factory 2 in winter. Compared with the existing data center room 1 in which most of the waste heat is directly discharged into the atmosphere and the plant factory 2 is heated by heating lamps, independent air conditioners and stoves in winter, on the one hand, the operating cost of the data center room 1 is reduced and the waste heat is converted into "negative carbon"; on the other hand, it can also promote the growth of plants in the plant factory 2 and improve the yield and quality of agricultural products.

[0043] In some other embodiments of the present invention, the evaporation unit includes an evaporator 32, and the evaporator 32 has a first heat exchange passage and a second heat exchange passage, the first heat exchange passage and the second heat exchange passage can exchange heat, and the second heat exchange passage is connected to the heat transfer passage 31. The first heat exchange passage is connected to the heat dissipation passage or the cooling fan of the data center room 1. By introducing the heat of the data center room 1 into the first heat exchange passage, the first heat exchange passage exchanges heat with the second heat exchange passage, and the evaporation heat absorption of the heat transfer medium is realized.

[0044] In some other embodiments, the condensing unit includes an air cooler 33, the air cooler 33 has a third heat exchange passage and a fourth heat exchange passage, the third heat exchange passage and the fourth heat exchange passage can exchange heat, and the fourth heat exchange passage is connected to the heat transfer passage 31. The third heat exchange passage is connected to the heating passage or the heating fan of the plant factory 2. By exchanging heat in the fourth heat exchange passage with the third heat exchange passage, condensation and heat release of the heat transfer medium are achieved.

[0045] The heat transfer medium can be gas, liquid or supercritical fluid, such as carbon dioxide, water or methanol.

[0046] Furthermore, in order to improve the heat transfer efficiency between the data center room 1 and the plant factory 2, in some embodiments of the present invention, the heat transfer channel 31 includes a first channel 311 and a second channel 312, the inlet of the second heat exchange passage is connected to the outlet of the fourth heat exchange passage through the first channel 311, and the outlet of the second heat exchange passage is connected to the inlet of the fourth heat exchange passage through the second channel 312. The purpose of such a setting is to make the steam transmission channel of the heat transfer medium and the condensed liquid transmission channel completely independent, the steam transmission of the heat transfer medium is carried out in the second channel 312, and the condensed liquid of the heat transfer medium is carried out in the first channel 311, thereby improving the heat transfer efficiency.

[0047] At the same time, a compressor 34 is provided on the second channel 312, and the compressor 34 is used to compress the heat transfer medium in the second channel 312, and compress the low-pressure heat transfer medium to a high-temperature and high-pressure state, which can further improve the heat transfer efficiency. A throttle valve 35 is provided on the first channel 311, and the throttle valve 35 is used to further reduce the pressure and temperature of the heat transfer medium in the first channel 311, and can also stabilize the pressure fluctuation of the heat transfer medium in the first channel 311.

[0048] In some other embodiments of the present invention, the specific structure of cooling the data center room 1 is as follows: a cooling unit 11 is provided in the data center room 1, and the cooling unit 11 is used to cool the data center room 1. The cooling unit 11 includes a first water tank 111, a first water pump 112, a first valve 113 and a cooling water pipeline 114, and the cooling water pipeline 114 sequentially connects the data center room 1, the first heat exchange path of the evaporator 32, the first water tank 111, the first water pump 112 and the first valve 113 in series to form a cooling circuit.

[0049] The first valve 113 controls the operation and stop of the cooling unit 11. Cold water is stored in the first water tank 111. The cold water enters the data center room 1 through the first water pump 112 and the first valve 113 to cool the data center room 1. The temperature of the cooled water increases and enters the first heat exchange path of the evaporator 32. The first heat exchange path exchanges heat with the second heat exchange path. The heat transfer medium in the second heat exchange path evaporates and absorbs heat, which can cool the water in the first heat exchange path. The cooled water enters the first water tank 111 and waits for the next cooling cycle.

[0050] In some other embodiments, the specific structure for heating and raising the temperature in the plant factory 2 is as follows: the plant factory 2 is provided with a heating unit 21, and the heating unit 21 is used to heat the plant factory 2. The heating unit 21 includes a second water tank 211, a second water pump 212, a second valve 213 and a heating water pipeline 214. The heating water pipeline 214 connects the plant factory 2, the third heat exchange path of the air cooler 33, the second water tank 211, the second water pump 212 and the second valve 213 in series in sequence to form a heating circuit.

[0051] Similarly, the second valve 213 controls the operation and stop of the heating unit 21. The second water tank 211 stores hot water. The hot water enters the plant factory 2 through the second water pump 212 and the second valve 213 to heat the plant factory 2. The water temperature after heating is reduced and enters the third heat exchange path of the air cooler 33. The third heat exchange path exchanges heat with the fourth heat exchange path. The heat transfer medium in the fourth heat exchange path condenses and releases heat, which can heat the water in the third heat exchange path. The heated water enters the second water tank 211 and waits for the next heating cycle.

[0052] The specific operation process of the plant factory heat supply system based on the recovery of waste heat from the data center room is explained by taking carbon dioxide as the heat transfer medium:

[0053] The second channel 312 inputs low-temperature and low-pressure gaseous carbon dioxide, which enters the compressor 34 and is compressed to a high-temperature and high-pressure supercritical state. The carbon dioxide at the outlet of the compressor 34 enters the fourth heat exchange passage in the air cooler 33, and the fourth heat exchange passage exchanges heat with the third heat exchange passage, and the water with a lower temperature returned in the heating water pipeline 214 of the plant factory 2 absorbs the compression heat of the carbon dioxide, and the water in the heating water pipeline 214 is heated, and the heated water enters the second water tank 211 for storage. The carbon dioxide in the fourth heat exchange passage in the air cooler 33 is cooled to form normal-temperature and high-pressure carbon dioxide, which then enters the throttle valve 35 to reduce the pressure, and the temperature further decreases, and then enters the second heat exchange passage of the evaporator 32 through the first channel 311, and the second heat exchange passage exchanges heat with the first heat exchange passage, and the carbon dioxide with a lower temperature is heated by the water with a higher temperature returned in the cooling water pipeline 114 of the data center computer room 1, and absorbs the heat from the water in the data center computer room 1, and then undergoes a new round of compression. This cycle eventually realizes the use of the heat from the data center room 1 to supply heat to the plant factory 2 in winter. Compared with the existing situation where most of the waste heat from the data center room 1 is directly discharged into the atmosphere and the plant factory 2 is heated by heating lamps, independent air conditioners and stoves in winter, on the one hand, it reduces the operating cost of the data center room 1 and converts waste heat into "negative carbon"; on the other hand, it can also promote the growth of plants in the plant factory 2 and increase the yield and quality of agricultural products.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
