Description

Technical Field

[0001] The invention relates to a green cavern-type data center operated by hydraulic power and a construction method and an operation method thereof, belonging to the technical field of cavern-type data center construction. Background Art

[0002] As a carrier of massive data, the demand for data centers has increased significantly, and the construction market will be in a rapid development stage for a long period of time. In order to meet the needs of data center security performance, Guizhou Province proposed and built a cave-type data center that is completely buried inside the mountain. It uses the external mountain as a shelter, which is significantly better than other types of data centers in terms of structural protection capabilities and has become a new direction for the development of data centers. However, the mountain outside the cave-type data center is relatively closed and cannot meet the rapid heat dissipation needs of the data center's IT equipment.

[0003] A Chinese patent document with publication number CN118292682A discloses a combined ecological building complex of a cavern-type data center. During operation, the computers inside the cavern of the horizontal data center continuously generate heat when working, causing the air to rise steadily and gather in the arch of the cavern of the horizontal data center. At this time, the hot air gathered at the top of the cross-section of the cavern of the horizontal data center is absorbed by the ceiling suction fan, and transmitted to the first heat exchanger through the hot air delivery pipe. The first heat exchanger converts the hot air into cold air through heat absorption treatment, and transmits it to the outside through the cold air delivery pipe, and then diffuses it relatively evenly into the cavern of the horizontal data center through the side vertical blower arranged on the side wall of the cavern of the horizontal data center, thereby realizing temperature control and regulation of the cavern of the horizontal data center.

[0004] However, the cave-type data center still has the following shortcomings: First, the air temperature in the horizontal data center cave is regulated to dissipate heat and cool down the IT equipment in the data center. This indirect temperature control method has a very limited effect on the heat dissipation and cooling of IT equipment. Second, the air in the horizontal data center cavern is used for heat exchange with IT equipment, the first heat exchanger, and inside the first heat exchanger, which has low heat exchange efficiency, further reducing the heat dissipation and cooling effect of the air in the horizontal data center cavern on IT equipment, and will lead to an increase in the energy consumption of the cavern-type data center; Third, the continuous operation of the added ceiling suction fans and side supply fans will also lead to an increase in the operating energy consumption of the cave-type data center.

[0011] A plurality of equipment storage tunnels are arranged side by side in the mountain, and one end of all the equipment storage tunnels is connected to the river water storage tunnel through a slope connecting tunnel.

[0012] The mountain is located on the convex bank side of the river channel bend, the river water storage tunnel is arranged between the slope connection tunnel and the river channel, and the two ends of the river water storage tunnel are connected to the two ends of the river channel bend in a one-to-one correspondence.

[0013] A water retaining dam is provided in the middle of the curved section of the river channel, the normal water storage level elevation of the water retaining dam is higher than the elevation of the top surface of the concrete partition in the river water storage tunnel, and the maximum water storage level elevation of the water retaining dam is lower than the elevation of the bottom surface of the equipment storage tunnel.

[0014] It also includes an electric power cavern, which is located inside the mountain and connected with the equipment storage tunnel. Hydropower generating equipment and a dam reserved channel are arranged in the water retaining dam. A pipeline layout channel is arranged on the top of the inner side of the river water storage tunnel, and the pipeline layout channel is connected with the dam reserved channel. Voltage conversion equipment, a distribution box and electric power storage equipment are arranged in the electric power cavern. The voltage conversion equipment is electrically connected to the hydropower generating equipment through a waterproof cable whose one end passes through the electric power cavern, the equipment storage tunnel, the slope connecting tunnel, the pipeline layout channel and the dam reserved channel in sequence.

[0015] It also includes roads and supporting buildings. The road is connected to one end of the equipment storage tunnel away from the river water storage tunnel. The supporting buildings are located on one side of the road and arranged close to the road.

[0016] A construction method of a green cavern-type data center using hydraulic power comprises the following steps: Step 1: Select the river and mountain where the cave-type data center is to be built, and then build roads and construction access roads; Step 2: Number all equipment storage tunnels, and then divide them into the first batch and the second batch according to odd and even numbers to construct the equipment storage tunnels.

[0017] A method for operating a green cavern-type data center using hydraulic power comprises the following steps: Step A, closing both ends of the equipment storage tunnel and filling the equipment storage tunnel with non-flammable gas; Step B, diverting the river water in the river channel to the river water storage tunnel through the inner water storage tank, and the excess river water in the inner water storage tank directly overflows into the outer drainage tank; Step C, starting the coolant circulation pump to allow the coolant to circulate in the jacket on the outer wall of the equipment cabinet, the coolant cold pipe, the coolant heat pipe and the liquid heat exchanger; Step D, start the river water circulation pump to pump the river water in the inner water storage tank to the liquid heat exchanger for heat exchange with the coolant. The coolant that has completed heat exchange in the liquid heat exchanger flows back to the jacket on the outer wall of the equipment cabinet to cool down and dissipate heat for the equipment cabinet. The river water that has completed heat exchange in the liquid heat exchanger is discharged into the outer drainage trough through the river water heat pipe.

[0018] After the equipment storage tunnel is filled with non-flammable gas, the internal oxygen concentration is lower than 15%.

[0019] The beneficial effects of the present invention are: 1. The river water storage tunnel stores river water diverted from the river channel. The river water in the river water storage tunnel is transported to the liquid heat exchanger through the river water transport component. The river water exchanges heat with the coolant in the liquid heat exchanger. The coolant cooled by the river water is transported to the equipment cabinet through the coolant transport component to directly cool and dissipate the heat of the equipment cabinet. This direct temperature control method significantly improves the heat dissipation and cooling effect of the IT equipment cabinet.

[0020] 2. The heat exchange between river water and the coolant in the liquid heat exchanger is carried out to achieve effective utilization of natural resources and reduce the operating costs of the cave-type data center. In addition, the continuous flow of river water can continuously maintain a relatively low temperature, ensuring the heat exchange efficiency and heat exchange effect between it and the coolant, and further ensuring the heat dissipation and cooling effect of the coolant on the IT equipment cabinet; the river water that completes the heat exchange with the coolant in the liquid heat exchanger is discharged to the outer drainage trough through the river water heat pipe, and then flows naturally to the downstream of the river channel along the outer drainage trough, with low energy consumption. At the same time, it avoids discharging the river water that has completed the heat exchange into the inner water storage tank, causing the internal river water temperature to rise, ensuring the cooling effect of the river water in the inner water storage tank on the coolant.

[0021] 3. Compared with the existing method of using air to exchange heat with air, the heat exchange between river water and coolant is high in heat exchange efficiency, which can improve the cooling effect of coolant on IT equipment cabinets, and also help reduce the operating energy consumption of cave-type data centers. There is no need to add suction fans and supply fans to dissipate heat and cool equipment cabinets, which further reduces the operating energy consumption of cave-type data centers.

[0022] 4. The main structure of the data center is set inside the mountain, and the hydropower generation equipment is placed inside the water retaining dam, so that the structural protection capability of the entire data center is significantly improved, which can effectively meet the information data security protection needs during wartime.

[0023] 5. The hydroelectric power generation equipment installed in the water retaining dam cooperates with the voltage conversion equipment, distribution box and power storage equipment in the power cavern to provide the electrical equipment in the data center with the required electric energy for operation, thus realizing the green and low-carbon operation of the data center.

[0024] 6. Fill the equipment storage tunnel with harmless and non-flammable gases such as nitrogen, and ensure that the oxygen concentration in the equipment storage tunnel is lower than 15%, so as to avoid fire in the equipment storage tunnel and significantly improve the operational safety of the cave-type data center.

[0025] 7. Construction of equipment storage tunnels in the first and second batches shall be divided into odd and even numbers, and construction of the second batch of equipment storage tunnels shall be started after the construction length of the first batch of equipment storage tunnels exceeds 50 meters, both of which can reduce mutual interference between adjacent equipment storage tunnels during the construction process.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0029] like Figures 1 to 5As shown, a green cave-type data center operated by hydraulic power described in the present invention comprises a river channel 1 and a mountain 2, wherein a river water storage tunnel 3 and a plurality of equipment storage tunnels 4 are arranged in the mountain 2, wherein the river water storage tunnel 3 is connected with the river channel 1, and the plurality of equipment storage tunnels 4 are connected with the river water storage tunnel 3 through slope connection tunnels 5 respectively, wherein the bottom elevation of the equipment storage tunnel 4 is higher than the top elevation of the river water storage tunnel 3, and one end of the slope connection tunnel 5 close to the river water storage tunnel 3 is inclined downward relative to the other end, wherein an equipment cabinet 7 and a liquid heat exchanger 8 are arranged in the equipment storage tunnel 4, wherein the liquid heat exchanger 8 is connected with the equipment cabinet 7 through a coolant delivery component 81, wherein a river water delivery component 83 is connected to the liquid heat exchanger 8, and an end of the river water delivery component 83 away from the liquid heat exchanger 8 passes through the slope connection tunnel 5 and extends into the river water storage tunnel 3. When in use, the bottom elevation of the equipment storage tunnel 4 is higher than the top elevation of the river water storage tunnel 3, and one end of the slope connection tunnel 5 close to the river water storage tunnel 3 is inclined downward relative to the other end; river water in the river water storage tunnel 3 is prevented from flowing into the equipment storage tunnel 4, effectively ensuring that the equipment installed in the equipment storage tunnel 4 can operate safely. The river water storage tunnel 3 stores river water diverted from the river channel, and the river water in the river water storage tunnel 3 is transported to the liquid heat exchanger 8 through the river water transport component 83. The river water exchanges heat with the coolant in the liquid heat exchanger 8. The coolant cooled by the river water is transported to the equipment cabinet 7 through the coolant transport component 81, and the equipment cabinet 7 is directly cooled and dissipated. This direct temperature control method significantly improves the heat dissipation and cooling effect of the IT equipment cabinet 7. Compared with the air-to-air heat exchange method in the prior art, the river water-to-coolant heat exchange method has high heat exchange efficiency, which can improve the cooling effect of the coolant on the IT equipment cabinet 7, and also help reduce the operating energy consumption of the cave-type data center. There is no need to add suction fans and supply fans to continuously operate to dissipate heat and cool the equipment cabinet 7, which further reduces the operating energy consumption of the cave-type data center.

[0030] The bottom of the inner side of the river water storage tunnel 3 is provided with a concrete partition 33 along its longitudinal direction. One side of the concrete partition 33 is the inner water storage tank 31, and the other side is the outer drainage tank 32. The inner water storage tank 31 is located between the outer drainage tank 32 and the slope connection tunnel 5. One end of the inner water storage tank 31 and the outer drainage tank 32 is provided with a blocking wall, and the other end is connected to the river channel 1. The connection point between the inner water storage tank 31 and the river channel 1 is located upstream of the connection point between the outer drainage tank 32 and the river channel 1. Figure 4As shown, a blocking wall is provided at the downstream end of the inner water storage tank 31, and a blocking wall is provided at the upstream end of the outer drainage tank 32. The river water in the river channel 1 flows into the inner water storage tank 31 through the upstream opening of the inner water storage tank 31 and is stored therein. Then, the river water in the inner water storage tank 31 is pumped to the liquid heat exchanger 8 by the river water circulation pump 833. The river water exchanges heat with the coolant in the liquid heat exchanger 8, thereby achieving the purpose of cooling the coolant. The heat exchange between the river water and the coolant in the liquid heat exchanger 8 realizes the effective utilization of natural resources and reduces the operating cost of the cavern-type data center. In addition, the continuous flow of river water can continuously maintain a relatively The lower temperature ensures the heat exchange efficiency and effect with the coolant, and further ensures the heat dissipation and cooling effect of the coolant on the IT equipment cabinet 7; the river water that completes the heat exchange with the coolant in the liquid heat exchanger 8 is discharged to the outer drainage trough 32 through the river water heat pipe 832, and then flows naturally along the outer drainage trough 32 to the downstream of the river channel 1, with low energy consumption. At the same time, it avoids discharging the river water that has completed the heat exchange into the inner water storage tank 31, which causes the internal river water temperature to rise, and ensures the cooling effect of the river water in the inner water storage tank 31 on the coolant.

[0031] The height of the concrete partition 33 is 1 / 2 to 2 / 3 of the height of the river water storage tunnel 3 , so that the excess river water in the inner water storage tank 31 can overflow into the outer drainage tank 32 through the concrete partition 33 .

[0032] The inner water storage tank 31 is provided with a valve and a filter 34 at one end thereof which is connected to the river channel 1. The valve is used to adjust the flow of river water entering the inner water storage tank 31, and the filter 34 is used to filter the incoming river water to prevent suspended matter in the river water from entering the inner water storage tank 31 and causing blockage thereof.

[0033] The river water transport component 83 includes a river water cooling pipe 831 and a river water heat pipe 832. One end of the river water cooling pipe 831 is connected to the water inlet of the liquid heat exchanger 8, and a river water circulation pump 833 is provided in the middle, and the other end extends to the inner water storage tank 31. One end of the river water heat pipe 832 is connected to the water outlet of the liquid heat exchanger 8, and the other end extends to the outer drainage tank 32.

[0034] A jacket is provided on the outer wall of the equipment cabinet 7; The cooling liquid delivery component 81 includes a cooling liquid cooling pipe 811 and a cooling liquid heat pipe 812. The cooling liquid cooling pipe 811 and the cooling liquid heat pipe 812 are both connected to the jacket on the outer wall of the equipment cabinet 7 and the liquid heat exchanger 8, and a cooling liquid circulation pump 813 is provided on the cooling liquid cooling pipe 811.

[0035] A plurality of equipment storage tunnels 4 are arranged side by side in the mountain 2 , and one end of all the equipment storage tunnels 4 is connected to the river water storage tunnel 3 through a slope connection tunnel 5 .

[0036] The mountain 2 is located on the convex bank side of the curved section of the river channel 1, and the river water storage tunnel 3 is arranged between the slope connection tunnel 5 and the river channel 1, and the two ends of the river water storage tunnel 3 are connected to the two ends of the curved section of the river channel 1 in a one-to-one correspondence. Figure 1 As shown, the river water storage tunnel 3 is arranged between the slope connecting tunnel 5 and the river channel 1, and the two ends of the river water storage tunnel 3 are connected to the two ends of the curved section of the river channel 1 one by one, which can reduce the excavation volume of the river water storage tunnel 3 and help reduce the project investment.

[0037] A water retaining dam 6 is provided in the middle of the curved section of the river channel 1. The normal water level elevation of the water retaining dam 6 is higher than the elevation of the top surface of the concrete partition 33 in the river water storage tunnel 3, and the maximum water level elevation of the water retaining dam 6 is lower than the elevation of the bottom surface of the equipment storage tunnel 4. It is ensured that the river water in the water retaining dam 6 can flow naturally into the river water storage tunnel 3, so as to facilitate the drainage of the river water in the river channel 1 into the inner water storage tank 31, but cannot flow naturally into the equipment storage tunnel 4, so as to prevent the river water from entering the equipment storage tunnel 4 and flooding the equipment cabinet 7. In addition, if the maximum water level elevation of the water retaining dam 6 is not lower than the elevation of the bottom surface of the equipment storage tunnel 4, the flow rate and the highest liquid level of the river water drained into the river water storage tunnel 3 can also be adjusted by adjusting the elevation of the connection port between the inner water storage tank 31 and the river channel 1, or adjusting the size of the connection port.

[0038] It also includes an electric power cavern 9, which is arranged in the mountain 2 and connected with the equipment storage tunnel 4. A hydroelectric power generation equipment 61 and a dam reserved channel 62 are arranged in the water retaining dam 6. A pipeline layout channel 35 is arranged on the top of the inner side of the river water storage tunnel 3, and the pipeline layout channel 35 is connected with the dam reserved channel 62. A voltage conversion device 91, a distribution box 92 and an electric power storage device 93 are arranged in the electric power cavern 9. The voltage conversion device 91 is electrically connected to the hydroelectric power generation equipment 61 through a waterproof cable whose one end passes through the electric power cavern 9, the equipment storage tunnel 4, the slope connection tunnel 5, the pipeline layout channel 35 and the dam reserved channel 62 in sequence. The distribution box 92 and the electric power storage device 93 are both electrically connected to the voltage conversion device 91, and the distribution box 92 is electrically connected to the electric power storage device 93. When in use, the hydroelectric power generation equipment 61 includes a hydroelectric generator set and a step-up transformer, the voltage conversion equipment 91 is a step-down transformer, and the power storage equipment 93 includes a rectifier, a battery, and an inverter. The electricity output by the hydroelectric generator set is stepped up by the step-up transformer and transmitted to the step-down transformer through a cable. The electricity stepped down by the step-down transformer is directly transmitted to the distribution box 92 in one way to supply power to the electrical equipment of the present invention, and is transmitted to the rectifier in the other way and stored in the battery after being rectified by the rectifier. When a short-term fault occurs in the hydroelectric power generation equipment 61, the DC power output by the battery is converted into AC power by the inverter and then transmitted to the distribution box 92 to supply power to the electrical equipment of the present invention, thereby ensuring the continuous, safe, and stable operation of the cave-type data center. In addition, if Figure 5 As shown, the step-up transformer is also externally connected to a grid line to transmit electricity to other electrical devices through the grid line.

[0039] It also includes a road 10 and supporting buildings 11. The road 10 is connected to one end of the equipment storage tunnel 4 away from the river water storage tunnel 3. The supporting buildings 11 are arranged on one side of the road 10 and close to the road 10. The supporting buildings 11 include dormitories, canteens, and the like.

[0040] A construction method of a green cavern-type data center using hydraulic power comprises the following steps: Step 1: Select the river channel 1 and mountain 2 where the cave-type data center is to be built, and then build the road 10 and the construction access road. When selecting, the river water in the river channel 1 is required to be abundant in all seasons to meet the heat dissipation and cooling needs of the data center and the power generation needs of the hydroelectric power generation equipment 61. The mountain 2 should not have major adverse geological bodies to ensure construction safety and controllable construction costs, and the size of the mountain 2 should be moderate to ensure that the equipment storage tunnel 4 is not too long or too short. The length of the mountain 2 should be controlled between 200m and 500m.

[0041] Step 2: Number all equipment storage tunnels 4, and then divide them into the first batch and the second batch according to odd and even numbers to construct equipment storage tunnels 4. During the construction of equipment storage tunnels 4, gradually advance from the road 10 side to the river channel 1 side. Divide the equipment storage tunnels 4 into the first batch and the second batch according to odd and even numbers to reduce the mutual interference of adjacent equipment storage tunnels 4 during the construction process.

[0042] Step 3: After the construction length of the first batch of equipment storage tunnels 4 exceeds 50 meters, start construction of the second batch of equipment storage tunnels 4 to reduce mutual interference between the first batch of equipment storage tunnels 4 and the second batch of equipment storage tunnels 4 during construction.

[0043] Step 4: After the first batch of equipment storage tunnels 4 are excavated to the designed length, continue to construct the slope connection tunnel 5 corresponding to the first batch of equipment storage tunnels 4; Step 5: Using the first batch of equipment storage tunnels 4 and slope connection tunnels 5 that have been completed as construction channels, multiple working surfaces are used to construct the main structure of the river water storage tunnel 3; Step 6: After the second batch of equipment storage tunnels 4 are excavated to the designed length and the main structure of the river water storage tunnel 3 is completed, the slope connection tunnel 5 corresponding to the second batch of equipment storage tunnels 4 is constructed; Step 7: After the construction of all slope connection tunnels 5 is completed, the auxiliary structure inside the river water storage tunnel 3 is constructed; Step 8: Relying on the road 10 and the construction access road, the water retaining dam 6 is constructed; Step nine: construct the power cavern 9 and supporting buildings 11, and complete the equipment installation and connection work in the equipment storage tunnel 4, the slope connection tunnel 5, the river water storage tunnel 3 and the water retaining dam 6.

[0044] A method for operating a green cavern-type data center using hydraulic power comprises the following steps: Step A, closing both ends of the equipment storage tunnel 4, and filling the equipment storage tunnel 4 with non-flammable gas; Step B: draining the river water in the river channel 1 into the river water storage tunnel 3 through the inner water storage tank 31, and the excess river water in the inner water storage tank 31 directly overflows into the outer drainage tank 32; Step C, start the coolant circulation pump 813 to circulate the coolant in the jacket on the outer wall of the equipment cabinet 7, the coolant cold pipe 811, the coolant heat pipe 812 and the liquid heat exchanger 8; Step D, start the river water circulation pump 833, pump the river water in the inner water storage tank 31 to the liquid heat exchanger 8 for heat exchange with the coolant, the coolant that has completed heat exchange in the liquid heat exchanger 8 flows back to the jacket on the outer wall of the equipment cabinet 7 to cool down and dissipate heat of the equipment cabinet 7, and the river water that has completed heat exchange in the liquid heat exchanger 8 is discharged into the outer drainage tank 32 through the river water heat pipe 832.

[0045] After the non-combustible gas is filled into the equipment storage tunnel 4, the oxygen concentration inside it is lower than 15%. When in use, the minimum oxygen concentration for combustion of electrical equipment is 15%. The combustion of combustibles is an oxidation reaction, which requires an oxygen concentration above the minimum to proceed. When it is lower than 15%, combustion cannot be maintained and the fire is extinguished.

[0046] Therefore, nitrogen and other harmless and non-flammable gases are filled into the equipment storage tunnel 4, and the oxygen concentration in the equipment storage tunnel 4 is ensured to be lower than 15%, thereby avoiding fire in the equipment storage tunnel 4. There are usually fewer staff in the data center, and if they need to enter the equipment storage tunnel 4, they can enter after wearing oxygen supply equipment.

[0047] Embodiment 1: The IT equipment cabinet 7 of the present invention adopts liquid cooling to cool down. Compared with the air cooling, the ventilation demand of the equipment storage tunnel 4 is greatly reduced. In order to meet the daily ventilation demand of the equipment storage tunnel 4, axial flow fans are installed on the top of the equipment storage tunnel 4, the slope connection tunnel 5 and the river water storage tunnel 3. Figure 6 As shown, when the wind is changed, the wind flows longitudinally along the equipment storage tunnel 4 into the slope connecting tunnel 5, then flows longitudinally along the slope connecting tunnel 5 into the river water storage tunnel 3, and finally is discharged outside the mountain 2 along the river water storage tunnel 3.
