Description

Technical Field

[0001] The invention relates to an ecological cavern-type data center based on island arrangement 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] In order to ensure the normal operation of the cavern-type data center, an air-cooling and heat dissipation solution using a ventilation shaft group has been proposed and successfully implemented. For example, 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 outward 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.

[0005] Based on this, in order to meet the green and low-carbon operation needs of cave-type data centers, combined with the environmental characteristics of islands in lakes or islands on the sea, it is of great practical significance to study an ecological cave-type data center based on island layout and its construction method and operation method.

The heat dissipation water pool is arranged on the island and connected to one end of the hot wastewater drainage channel located outside the data tunnel. One end of the concealed water pool drainage channel is connected to the heat dissipation water pool, and the other end slopes downward and extends to the external waters on the gentle slope side of the mountain.

[0014] The mountain is also equipped with a fuel storage tunnel, a fuel generator tunnel, a command center tunnel, a power cavern and a communication channel. The fuel storage tunnel is located near the edge of the mountain, the fuel generator tunnel is arranged next to the fuel storage tunnel, the command center tunnel and the power cavern are both arranged between the fuel generator tunnel and the data tunnel group, and the communication channel connects the fuel storage tunnel, the fuel generator tunnel, the command center tunnel, the power cavern and all the data tunnels.

[0015] One end of the command center tunnel and the power cavern both penetrate the mountain, and windproof doors are provided at the entrances of the data tunnel, fuel storage tunnel, fuel generator tunnel, command center tunnel and power cavern.

[0016] A ventilation shaft is provided at the top of the fuel generator tunnel, and a fuel generator is provided in the fuel generator tunnel; The command center tunnel is provided with an office area and a rest area, and the office area is provided with offices, meeting rooms and a monitoring room.

[0017] The power cavern is provided with a voltage conversion device, a distribution box and a power storage device. The voltage conversion device is electrically connected to an external high-voltage power grid. The distribution box and the power storage device are both electrically connected to the voltage conversion device, and the distribution box is electrically connected to the power storage device.

[0018] It also includes a ship berthing wharf and a water power generation planning area. The ship berthing wharf is located on the island and on the gentle slope of the mountain. The water power generation planning area is set around the island and leaves a channel for ships to enter and exit; The water power generation planning area is equipped with clean energy power generation equipment, and the clean energy power generation equipment is one or more of a wind power generation system, a tidal power generation system and a solar power generation system.

[0019] The priority order of using the external high-voltage power grid, power storage equipment, clean energy power generation equipment and fuel generator to power the ecological cavern-type data center is: power supply from clean energy power generation equipment, power supply from external high-voltage power grid, power supply from fuel generator and power storage equipment.

[0020] A construction method of an ecological cavern-type data center based on island layout, comprising the following steps: Step 1, selecting an island and a mountain where an ecological cavern-type data center is to be constructed through survey, and constructing a ship berthing pier and an island road on the island; Step 2: uniformly number the fuel storage tunnel, fuel generator tunnel, command center tunnel, power cavern and all data tunnels, and then divide the tunnels into the first batch and the second batch according to odd and even numbers; Step 3: After the construction length of the first batch of tunnels exceeds 50 meters, start the construction of the second batch of tunnels, and reserve the intersection with the connecting channel during the tunnel construction process; Step 4: After all tunnels are constructed, construct the communication channel; Step 5: construct a heat dissipation pool and a buried pool drainage channel on the gentle slope platform of the island, and connect the heat dissipation pool with the hot wastewater drainage channel; Step 6: Determine the type of clean energy power generation equipment according to the environmental conditions of the island, install the clean energy power generation equipment in the water power generation planning area, and then complete the connection between the voltage conversion equipment and the external high-voltage power grid; Step 7: Complete the installation and connection of indoor equipment in the data tunnel, fuel storage tunnel, fuel generator tunnel, command center tunnel and power tunnel.

[0021] An operation method of an ecological cavernous data center based on island layout comprises the following steps: Step A, closing the windproof door at the entrance of the data tunnel and filling the data tunnel with non-flammable gas; Step B, start the coolant circulation pump to circulate the coolant 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 C, start the water pump to transport the water in the external water area on the steep slope side of the mountain to the liquid heat exchanger for heat exchange with the coolant. The coolant that has completed the heat exchange in the liquid heat exchanger flows back to the jacket on the outer wall of the equipment cabinet to continue cooling and dissipating the equipment cabinet. The water that has completed the heat exchange in the liquid heat exchanger is discharged into the hot wastewater drainage channel through the hot wastewater discharge pipe, and then flows through the heat dissipation water pool and the buried water pool drainage channel in turn and is discharged into the external water area on the gentle slope side of the mountain.

[0022] The non-flammable gas filled into the data tunnel is nitrogen, and after the data tunnel is filled with nitrogen, the oxygen concentration inside the data tunnel is lower than 15%.

[0023] When the data tunnel needs to be ventilated, the windproof door at the opening can be opened.

[0024] The beneficial effects of the present invention are: 1. Water from the external water area is transported to the liquid heat exchanger through the water transport component. The water exchanges heat with the coolant in the liquid heat exchanger. The coolant after water cooling 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 equipment cabinet.

[0025] 2. Using water and coolant for heat exchange has high heat exchange efficiency, which can improve the heat dissipation and cooling effect of the coolant on the equipment cabinet, and also help to reduce the operating energy consumption of the cave-type data center.

[0026] 3. Make full use of the natural, cold water in the external waters around the island to exchange heat with the coolant in the liquid heat exchanger, and finally use the coolant to dissipate heat and cool the equipment cabinets, significantly reducing the operating costs of the cave-type data center.

[0027] 4. The data tunnel is set with a longitudinal slope of not less than 0.3% to ensure that the hot wastewater drainage channel can naturally and smoothly drain the hot wastewater, which helps to reduce the operating costs of the ecological cave data center.

[0028] 5. One end of the cold water delivery pipe extends to the external waters on the steep slope side of the mountain through the cold water pipe inlet channel, so as to protect the cold water delivery pipe through the cold water pipe inlet channel to prevent the cold water delivery pipe from being damaged by waves or human factors.

[0029] 6. The liquid heat exchanger takes water from the external water area on the steep slope side of the mountain through the cold water inlet component to exchange heat with the coolant flowing through it. The hot water formed is discharged to the external water area on the gentle slope side of the mountain through the hot wastewater discharge component, the heat dissipation pool and the buried water pool drainage channel. It can be seen that the water intake points and drainage points are distributed on both sides of the mountain, which can avoid the hot water discharged from the discharge point causing the water temperature at the water intake point to rise, ensuring that the water transported to the liquid heat exchanger by the cold water inlet component continues to maintain a low temperature, further ensuring the heat exchange effect between water and coolant in the liquid heat exchanger, and ultimately ensuring the heat dissipation and cooling effect of the coolant on the equipment cabinet.

[0030] 7. In the daily working mode, clean energy power generation equipment is used to power the ecological cavern data center. If there is excess power, it is stored in batteries. When the power supply capacity of the clean energy power generation equipment is insufficient, the external high-voltage power grid is used first. If there is no external high-voltage power grid or the external high-voltage power grid is out of power, fuel generators are used for power supply. Batteries are used as the last means of power supply. Ensure that the ecological cavern data center operates green, low-carbon, continuous, safe and stable.

[0031] 8. Constructing tunnels in the first and second batches according to odd and even numbers, and constructing the second batch of tunnels after the construction length of the first batch of tunnels exceeds 50 meters, can reduce mutual interference between adjacent tunnels during the construction process.

[0032] 9. Fill the data tunnel with harmless and non-flammable gases such as nitrogen, and ensure that the oxygen concentration in the data tunnel is less than 15% to avoid fire in the data tunnel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0036] like Figures 1 to 6 As shown, an ecological cave-type data center based on island layout described in the present invention includes an island 1, a mountain 2 is disposed on the island 1, a group of data tunnels 3 are disposed in the mountain 2, and the data tunnel 3 runs through the mountain 2, an equipment cabinet 10 and a liquid heat exchanger 9 are disposed in the data tunnel 3, the liquid heat exchanger 9 is connected to the equipment cabinet 10 through a coolant delivery component 91, a water delivery component 93 is connected to the liquid heat exchanger 9, and the water delivery component 93 is connected to the external water area 15 surrounding the island 1.

[0037] Specifically, the island 1 may be an island in a lake 1 or an island on the sea 1. Figure 3 As shown, when there are multiple liquid heat exchangers 9 and multiple equipment cabinets 10 in the data tunnel 3, the liquid heat exchangers 9 and the equipment cabinets 10 are arranged alternately in the longitudinal direction of the data tunnel 3 so that one liquid heat exchanger 9 can achieve heat exchange with two equipment cabinets 10 at the same time.

[0038] When in use, water from the external water area 15 is transported to the liquid heat exchanger 9 through the water transport component 93, and the water exchanges heat with the coolant in the liquid heat exchanger 9. The coolant after water cooling is transported to the equipment cabinet 10 through the coolant transport component 91, and the equipment cabinet 10 is directly cooled and dissipated. This direct temperature control method significantly improves the heat dissipation and cooling effect of the equipment cabinet 10. Compared with the method of using air to air for heat exchange in the prior art, the use of water and coolant for heat exchange has a high heat exchange efficiency, which can improve the heat dissipation and cooling effect of the coolant on the equipment cabinet 10, and also helps to reduce the operating energy consumption of the cave-type data center. There is no need to add equipment such as suction fans and supply fans to continuously operate to dissipate heat and cool the equipment cabinet 10, which further reduces the operating energy consumption of the cave-type data center.

[0039] The water in the natural, cold external waters 15 surrounding the island 1 is fully utilized to exchange heat with the coolant in the liquid heat exchanger 9, and finally the equipment cabinet 10 is cooled and cooled by the coolant, which significantly reduces the operating cost of the cave-type data center.

[0040] The water delivery component 93 includes a cold water inlet component 931 and a hot waste water discharge component 932. One end of the cold water inlet component 931 is connected to the liquid heat exchanger 9, and the other end extends to the external water area 15 on the steep slope side of the mountain 2. The hot waste water discharge component 932 is connected to the liquid heat exchanger 9 and extends from the lower end hole of the data tunnel 3 to the outside of the data tunnel 3. When in use, the cold water in the external water area 15 on the steep slope side of the mountain 2 is delivered to the liquid heat exchanger 9 through the cold water inlet component 931 to exchange heat with the coolant, and the hot water formed by the heat exchange in the liquid heat exchanger 9 is discharged to the outside of the data tunnel 3 through the hot waste water discharge component 932.

When in use, IT equipment such as equipment cabinets 10 are installed in the data tunnel 3; the data tunnel 3 is set with a longitudinal slope of not less than 0.3% to ensure that the hot wastewater drainage channel 9322 can naturally and smoothly realize the hot wastewater drainage, which helps to reduce the operating cost of the ecological cave data center.

[0043] The inner wall of the data tunnel 3 is provided with a lining 31, and the inner wall of the lining 31 is provided with a partition 32, and the partition 32 divides the space inside the lining 31 into two parts, an upper part and a lower part, and a support frame 33 is provided on the inner wall of the lining 31 above the partition 32. When in use, the partition 32 is used as a force-bearing platform for equipment installation, and equipment such as the liquid heat exchanger 9 and the equipment cabinet 10 are all installed on the partition 32. The support frame 33 is used to support the cold water delivery pipe 9311 and other pipelines passing through the data tunnel 3.

[0044] A cold water pipe inlet channel 35 is inclined at the bottom of the data tunnel 3 near its upper end, and the lower end of the cold water pipe inlet channel 35 passes through the mountain 2 and extends to the external water area 15 on the steep slope side of the mountain 2, and the upper end passes through the bottom plate of the lining 31.

[0045] The cold water inlet assembly 931 includes a cold water delivery pipe 9311 and a water pump 9312. One end of the cold water delivery pipe 9311 is connected to the liquid heat exchanger 9, the middle part is erected on the support frame 33, and the other end is arranged along the data tunnel 3 and the cold water pipe inlet channel 35, and extends to the external water area 15 on the steep slope side of the mountain 2. The water pump 9312 is installed on the cold water delivery pipe 9311 and is located in the data tunnel 3. When in use, one end of the cold water delivery pipe 9311 extends to the external water area 15 on the steep slope side of the mountain 2 through the cold water pipe inlet channel 35, so as to form a protection for the cold water delivery pipe 9311 through the cold water pipe inlet channel 35, and prevent the cold water delivery pipe 9311 from being damaged by waves or human factors. After starting the water pump 9312, the water in the external water area 15 on the steep slope side of the mountain 2 can be pumped to the liquid heat exchanger 9 along the cold water delivery pipe 9311.

One end of the hot wastewater discharge pipe 9321 is connected to the liquid heat exchanger 9, and the other end passes through the partition 32 and extends to the top of the hot wastewater drainage channel 9322 or to the inside of the hot wastewater drainage channel 9322. When in use, the cold water in the external water area 15 is converted into hot water after heat exchange with the coolant in the liquid heat exchanger 9. Then the hot water is discharged into the hot wastewater drainage channel 9322 through the hot wastewater discharge pipe 9321, and flows to the outside of the data tunnel 3 through the hot wastewater drainage channel 9322.

[0047] It also includes a heat sink 11 and a buried pool drainage channel 12 arranged on the gentle slope platform of the island 1.

[0053] It also includes a ship berthing wharf 13 and a water power generation planning area 14.

The water power generation planning area 14 is provided with clean energy power generation equipment, and the clean energy power generation equipment is one or more of a wind power generation system, a tidal power generation system and a solar power generation system.

[0054] When the wind power in the area where the island 1 is located is sufficient, a wind power generation system can be installed on the gentle slope platform of the island 1, the mountain 2 or / and the water power generation planning area 14.

[0055] When the tidal effect in the area where the island 1 is located is relatively obvious, a tidal power generation system can be installed in the water power generation planning area 14.

[0056] When the area where the island 1 is located has sufficient sunshine, a solar power generation system can be installed at a suitable location such as a gentle slope platform of the island 1, a mountain 2 or / and a water power generation planning area 14.

[0057] The electricity generated by the clean energy power generation equipment is first supplied to the power consumption equipment in the data center, and then stored in the power storage device 73. Finally, if there is excess electricity, it can be transmitted to other power consumption equipment through the external high-voltage power grid 74. Wind power generation systems, tidal power generation systems and solar power generation systems are all existing technologies and will not be described in detail here.

[0058] The above-mentioned clean energy power generation methods can be selected in one or more combinations, which are mainly used to meet the self-operation requirements of the ecological cavern-type data center. In addition, when the area where the island 1 is located is close to the external high-voltage power grid 74, the external high-voltage power grid 74 can be electrically connected to the voltage conversion device 71 as a power supply preparation method for the ecological cavern-type data center.

[0059] The priority order of using the external high-voltage power grid 74, power storage device 73, clean energy power generation equipment and fuel generator 52 to power the ecological cavern data center is: power supply by clean energy power generation equipment, power supply by external high-voltage power grid 74, power supply by fuel generator 52, and power supply by power storage device 73. In the daily working mode, the clean energy power generation equipment is used to power the ecological cavern data center, and if there is excess power, it is stored by batteries; when the power supply capacity of the clean energy power generation equipment is insufficient, the external high-voltage power grid 74 is used for power supply first; if there is no external high-voltage power grid 74 or the external high-voltage power grid 74 is out of power, the fuel generator is used for power supply; the battery is used as the last means of power supply to ensure the green, low-carbon, continuous, safe and stable operation of the ecological cavern data center.

[0060] A construction method of an ecological cavern-type data center based on island layout includes the following steps: Step 1: select an island 1 and a mountain 2 where an ecological cavern-type data center is to be constructed through survey, and construct a ship berthing pier 13 and an island road on the island 1. The mountain 2 should not have major adverse geological bodies to ensure construction safety and controllable construction costs, and the size of the mountain should be moderate to ensure that the data tunnel 3 is not too long or too short. The length of the data tunnel 3 should be controlled between 200m and 500m.

[0061] Step 2: uniformly number the fuel storage tunnel 4, fuel generator tunnel 5, command center tunnel 6, power cavern 7 and all data tunnels 3, and then divide the tunnels into the first and second batches according to odd and even numbers. Divide the tunnels into the first and second batches according to odd and even numbers to reduce mutual interference between adjacent tunnels during construction.

[0062] Step 3: After the construction length of the first batch of tunnels exceeds 50 meters, the second batch of tunnels will be constructed, and the intersection with the communication channel 8 will be reserved during the tunnel construction process to reduce the mutual interference between the first batch of tunnels and the second batch of tunnels during the construction process.

[0063] Step 4: After all tunnels are constructed, construct the communication channel 8.

[0064] Step 5: construct a heat dissipation pool 11 and a concealed pool drainage channel 12 on the gentle slope platform of the island 1, and connect the heat dissipation pool 11 with the hot wastewater drainage channel 9322.

[0065] Step 6: Determine the type of clean energy power generation equipment according to the environmental conditions of the island 1 , install the clean energy power generation equipment in the water power generation planning area 14 , and then complete the connection between the voltage conversion equipment 71 and the external high-voltage power grid 74 .

[0066] Step seven: Complete the installation and connection of equipment in the data tunnel 3, fuel storage tunnel 4, fuel generator tunnel 5, command center tunnel 6 and power cavern 7.

[0067] An operation method of an ecological cavernous data center based on island layout comprises the following steps: Step A, closing the windproof door at the entrance of the data tunnel 3, and filling the data tunnel 3 with non-flammable gas; Step B, start the coolant circulation pump 913 to circulate the coolant in the jacket on the outer wall of the equipment cabinet 10, the coolant cooling pipe 911, the coolant heat pipe 912 and the liquid heat exchanger 9; Step C, start the water pump 9312, and transport the water in the external water area 15 on the steep slope side of the mountain 2 to the liquid heat exchanger 9 for heat exchange with the coolant. The coolant that has completed the heat exchange in the liquid heat exchanger 9 flows back to the jacket on the outer wall of the equipment cabinet 10 to continue cooling and dissipating the equipment cabinet 10. The water that has completed the heat exchange in the liquid heat exchanger 9 is discharged into the hot waste water drainage channel 9322 through the hot waste water discharge pipe 9321, and then flows through the heat dissipation water pool 11 and the buried water pool drainage channel 12 in turn and is discharged into the external water area 15 on the gentle slope side of the mountain 2.

[0068] The non-combustible gas filled in the data tunnel 3 is nitrogen, and after the nitrogen is filled in the data tunnel 3, the oxygen concentration inside is less 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 less than 15%, the combustion cannot be maintained and the fire is extinguished.

[0069] Therefore, nitrogen and other harmless and non-flammable gases are filled into the data tunnel 3, and the oxygen concentration in the data tunnel 3 is ensured to be lower than 15%, so as to avoid fire in the data tunnel 3. There are usually fewer staff in the data center. If they need to enter the data tunnel 3, they can enter after wearing oxygen supply equipment.

[0070] When the data tunnel 3 needs to be ventilated, the windproof door at the opening thereof can be opened.
