Description

Technical Field

[0001] The present invention relates to a green cave-type data center operated by hydraulic power, its construction method and operation method, and belongs to the technical field of cave-type data center construction. Background Art

[0002] As a carrier of massive data, the demand for data centers has increased significantly, and its construction market will be in a rapid development stage for a long time. To meet the requirements of the security performance of data centers, Guizhou region has proposed and constructed a cave-type data center integrally buried inside the mountain body. Using the external mountain body as a shelter, its structural protection ability is significantly better than that of other types of data centers, and it has become a new direction for the development of data centers. However, the mountain body outside the cave-type data center is relatively enclosed and cannot meet the rapid heat dissipation requirements of the IT equipment in the data center.

[0003] Chinese patent document with the publication number CN118292682A discloses a combined ecological building complex of a cave-type data center. During operation, when the computers in the horizontal data center chamber work, heat is continuously generated, causing the air to rise steadily and accumulate in the arch of the horizontal data center chamber. At this time, the ceiling suction fan absorbs the hot air accumulated at the top of the cross-section of the horizontal data center chamber and transmits it 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 horizontal data center chamber through the side-standing air supply fans arranged at the side walls of the horizontal data center chamber, thereby realizing the temperature control adjustment of the horizontal data center chamber.

[0004] However, the cave-type data center still has the following deficiencies:

[0005] First, by regulating the air temperature in the horizontal data center chamber to achieve the purpose of dissipating heat and cooling the IT equipment in the data center, this indirect temperature control method has extremely limited effects on the heat dissipation and cooling of the IT equipment.

[0006] Second, the air in the horizontal data center chamber exchanges heat with the IT equipment, the first heat exchanger, and inside the first heat exchanger all by air, with low heat exchange efficiency, further reducing the heat dissipation and cooling effects of the air in the horizontal data center chamber on the IT equipment, and causing an increase in the operating energy consumption of the cave-type data center.

[0007] Third, the continuous operation of the additional ceiling suction fan and side-standing air supply fans will also cause an increase in the operating energy consumption of the cave-type data center. Summary of the Invention

[0008] To solve the above technical problems, the present invention provides a green cave - type data center operated by hydraulic power, as well as its construction method and operation method.

[0009] The present invention is achieved through the following technical solutions:

[0010] A green cave - type data center operated by hydraulic power, comprising a river course and a mountain body. Inside the mountain body, there are a river water storage tunnel and several equipment storage tunnels.

The bottom elevation of the equipment storage tunnel is higher than the top elevation of the river water storage tunnel, and one end of the slope - connecting tunnel close to the river water storage tunnel slopes downward relative to the other end. Inside the equipment storage tunnel, there are equipment cabinets and liquid heat exchangers. The liquid heat exchangers are connected to the equipment cabinets through a coolant delivery assembly, and a river water delivery assembly is connected to the liquid heat exchangers. The end of the river water delivery assembly far from the liquid heat exchanger passes through the slope - connecting tunnel and extends into the river water storage tunnel;

[0011] At the bottom of the inner side of the river water storage tunnel, a concrete partition is longitudinally provided along it. One side of the concrete partition is an inner water storage tank, and the other side is an outer drainage tank. The inner water storage tank is located between the outer drainage tank and the slope - connecting tunnel. One end of the inner water storage tank and the outer drainage tank is provided with a blocking wall, and the other end is connected to the river course. And the connection point of the inner water storage tank with the river course is upstream of the connection point of the outer drainage tank with the river course.

[0012] The height of the concrete partition is 1 / 2 to 2 / 3 of the height of the river water storage tunnel.

[0013] At the end of the inner water storage tank connected to the river course, there are a valve and a filter.

[0014] The river water delivery assembly includes a river water cold pipe and a river water heat pipe. One end of the river water cold pipe is connected to the water inlet of the liquid heat exchanger, a river water circulation pump is provided in the middle, and the other end extends into the inner water storage tank.

[0017] A plurality of equipment storage tunnels are arranged side by side inside the mountain body, and one end of all the equipment storage tunnels is respectively connected to the river water storage tunnel through slope - connecting tunnels.

[0018] The mountain body is located on the convex bank side of the curved section of the river channel. The river water storage tunnel is arranged between the slope connecting tunnel and the river channel, and both ends of the river water storage tunnel are correspondingly connected to both ends of the curved section of the river channel.

[0019] A water retaining dam is provided in the middle of the curved section of the river channel. The normal storage water 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 storage water level elevation of the water retaining dam is lower than the elevation of the bottom surface of the equipment storage tunnel.

[0020] It further includes a power chamber, which is arranged in the mountain body and is connected to the equipment storage tunnel. A hydroelectric power generation device and a reserved passage for the dam are provided in the water retaining dam. A pipeline layout passage is provided at the top inside the river water storage tunnel, and the pipeline layout passage is connected to the reserved passage for the dam. A voltage conversion device, a distribution box and a power storage device are provided in the power chamber. The voltage conversion device is electrically connected to the hydroelectric power generation device through a waterproof cable that sequentially passes through the power chamber, the equipment storage tunnel, the slope connecting tunnel, the pipeline layout passage and the reserved passage for the dam at one end. 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.

[0021] It further includes a road and supporting buildings. The road is connected to the end of the equipment storage tunnel far from the river water storage tunnel, and the supporting buildings are arranged on one side of the road and close to the road.

[0022] A construction method for a green cave-type data center operated by hydropower includes the following steps:

[0023] Step 1: Select the river channel and mountain body for the proposed cave-type data center, and then build a road and a construction access road.

[0024] Step 2: Number all the equipment storage tunnels, and then construct the equipment storage tunnels in the first batch and the second batch according to odd and even numbers. When constructing the equipment storage tunnels, gradually advance from the road side to the river channel side.

[0025] Step 3: After the construction length of the first batch of equipment storage tunnels exceeds 50 meters, start constructing the second batch of equipment storage tunnels.

[0026] Step 4: After the first batch of equipment storage tunnels are excavated to the designed length, continue to construct the slope connecting tunnels corresponding to the first batch of equipment storage tunnels.

[0027] Step 5: Take the first batch of equipment storage tunnels and slope connecting tunnels that have been completed as construction channels, and construct the main structure of the tunnel body of the river water storage tunnel with multiple working faces.

[0028] Step 6: After the second batch of equipment storage tunnels are excavated to the designed length and the main structure of the river water storage tunnel is completed, start construction of the slope connection tunnel corresponding to the second batch of equipment storage tunnels;

[0029] Step 7: After the construction of all slope connection tunnels is completed, the auxiliary structures inside the river water storage tunnel are constructed;

[0030] Step 8: Relying on roads and construction access roads, carry out water retaining dam construction;

[0031] Step 9: Construct the power cavern and supporting buildings, and complete the equipment installation and connection work in the equipment storage tunnel, slope connection tunnel, river water storage tunnel and water retaining dam.

[0032] A method for operating a green cavern-type data center using hydraulic power comprises the following steps:

[0033] Step A, closing both ends of the equipment storage tunnel and filling the equipment storage tunnel with non-flammable gas;

[0034] 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;

[0035] 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;

[0036] 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.

[0037] After the equipment storage tunnel is filled with non-flammable gas, the internal oxygen concentration is lower than 15%.

[0038] The beneficial effects of the present invention are:

[0039] 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.

[0040] 2. Heat exchange is carried out between the river water and the coolant in the liquid heat exchanger, realizing the effective utilization of natural resources and reducing the operating cost of the cave-type data center. In addition, the continuous river water can continuously maintain a relatively low temperature, ensuring the heat exchange efficiency and effect between it and the coolant, and further guaranteeing the heat dissipation and cooling effect of the coolant on the IT equipment cabinets; the river water that has completed heat exchange with the coolant in the liquid heat exchanger is discharged into the outer drainage trough through the river heat pipe, and then naturally flows to the downstream of the river along the outer drainage trough, with low energy consumption. At the same time, it avoids discharging the river water that has completed heat exchange into the inner water storage trough, resulting in an increase in the temperature of the river water inside, ensuring the cooling effect of the river water in the inner water storage trough on the coolant.

[0041] 3. Compared with the existing heat exchange method using air-to-air heat exchange, using river water-to-coolant heat exchange has a high heat exchange efficiency, can improve the heat dissipation and cooling effect of the coolant on the IT equipment cabinets, and also helps to reduce the operating energy consumption of the cave-type data center. There is no need to add suction fans and supply fans to dissipate heat and cool the equipment cabinets, further reducing the operating energy consumption of the cave-type data center.

[0042] 4. The main structure of the data center is set inside the mountain, and the hydraulic power generation equipment is installed in the water retaining dam, significantly improving the structural protection ability of the entire data center and effectively meeting the information data security protection requirements during wartime.

[0043] 5. The hydraulic power generation equipment installed in the water retaining dam, in cooperation with the voltage conversion equipment, distribution box and power storage equipment in the power tunnel, provides the electrical energy required for the operation of the electrical equipment in the data center, thus realizing the green and low-carbon operation of the data center.

[0044] 6. Inert and non-flammable gases such as nitrogen are filled into the equipment storage tunnel, and the oxygen concentration in the equipment storage tunnel is ensured to be lower than 15%, thus avoiding fires in the equipment storage tunnel and significantly improving the operation safety of the cave-type data center.

[0045] 7. The equipment storage tunnel is constructed in the first batch and the second batch according to odd and even numbers. After the construction length of the first batch of equipment storage tunnels exceeds 50 meters, the construction of the second batch of equipment storage tunnels is started, both of which can reduce the mutual interference between adjacent equipment storage tunnels during the construction process.

Detailed implementation manners

[0053] The technical solution of the present invention will be further described below, but the scope of protection is not limited thereto.

[0054] As Figures 1 to 5As shown in the figure, a green cave - type data center using hydraulic operation according to the present invention includes a river channel 1 and a mountain body 2. Inside the mountain body 2, there are a river water storage tunnel 3 and a plurality of equipment storage tunnels 4. The river water storage tunnel 3 is connected to the river channel 1. The plurality of equipment storage tunnels 4 are respectively connected to the river water storage tunnel 3 through slope - connecting tunnels 5. 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 - connecting tunnel 5 close to the river water storage tunnel 3 slopes downward relative to the other end. Inside the equipment storage tunnel 4, there are equipment cabinets 7 and liquid heat exchangers 8. The liquid heat exchangers 8 are connected to the equipment cabinets 7 through coolant delivery components 81. A river water delivery component 83 is connected to the liquid heat exchangers 8. One end of the river water delivery component 83 far from the liquid heat exchanger 8 passes through the slope - connecting tunnel 5 and extends into the river water storage tunnel 3. During 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 - connecting tunnel 5 close to the river water storage tunnel 3 slopes downward relative to the other end, preventing the river water in the river water storage tunnel 3 from flowing into the equipment storage tunnel 4 and effectively ensuring the safe operation of the equipment installed in the equipment storage tunnel 4. The river water storage tunnel 3 stores river water diverted from the river channel 1. The river water in the river water storage tunnel 3 is delivered to the liquid heat exchanger 8 through the river water delivery component 83. The river water exchanges heat with the coolant in the liquid heat exchanger 8. The coolant cooled by the river water is delivered to the equipment cabinets 7 through the coolant delivery component 81 to directly cool and dissipate heat from the equipment cabinets 7. This direct temperature control method significantly improves the heat dissipation and cooling effect on the IT equipment cabinets 7. Compared with the prior art method of heat exchange between air and air, using river water to exchange heat with the coolant has a high heat exchange efficiency, can improve the heat dissipation and cooling effect of the coolant on the IT equipment cabinets 7, 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 for heat dissipation and cooling of the equipment cabinets 7, further reducing the operating energy consumption of the cave - type data center.

[0055] At the bottom of the inner side of the river water storage tunnel 3, a concrete partition 33 is provided longitudinally. One side of the concrete partition 33 is an inner water storage tank 31, and the other side is an outer drainage tank 32. The inner water storage tank 31 is located between the outer drainage tank 32 and the slope - connecting 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 of the inner water storage tank 31 and the river channel 1 is upstream of the connection point of the outer drainage tank 32 and the river channel 1. As 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; by using the river water to exchange heat with the coolant in the liquid heat exchanger 8, the effective utilization of natural resources is realized, and the operation cost of the cave-type data center is reduced. In addition, the continuous river water can continuously maintain a relatively low temperature, ensuring the heat exchange efficiency and heat exchange effect with the coolant, and further ensuring the heat dissipation and cooling effect of the coolant on the IT equipment cabinet 7; the river water that has completed heat exchange with the coolant in the liquid heat exchanger 8 is discharged into the outer drainage tank 32 through the river water heat pipe 832, and then naturally flows downstream along the outer drainage tank 32 to the river channel 1. The energy consumption is low, and at the same time, it is avoided that the river water that has completed heat exchange is discharged into the inner water storage tank 31, resulting in an increase in the internal river water temperature, ensuring the cooling effect of the river water in the inner water storage tank 31 on the coolant.

[0056] The height of the concrete partition 33 is 1 / 2 to 2 / 3 of the height of the river water storage tunnel 3. The excess river water in the inner water storage tank 31 can overflow into the outer drainage tank 32 through the concrete partition 33.

[0057] One end of the inner water storage tank 31 communicating with the river channel 1 is provided with a valve and a filter 34. It is convenient to adjust the flow rate of the river water entering the inner water storage tank 31 through the valve, and the incoming river water is filtered through the filter 34 to prevent suspended substances in the river water from entering the inner water storage tank 31 and causing blockage.

[0058] The river water conveying assembly 83 includes a river water cold pipe 831 and a river water heat pipe 832. One end of the river water cold pipe 831 is connected to the water inlet of the liquid heat exchanger 8, a river water circulation pump 833 is provided in the middle, and the other end extends into 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 into the outer drainage tank 32.

[0059] A jacket is provided on the outer wall of the equipment cabinet 7;

[0060] The coolant conveying assembly 81 includes a coolant cold pipe 811 and a coolant heat pipe 812. The coolant cold pipe 811 and the coolant 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 coolant circulation pump 813 is provided on the coolant cold pipe 811.

[0061] A plurality of equipment storage tunnels 4 are arranged side by side in the mountain body 2, and one end of all the equipment storage tunnels 4 is respectively communicated with the river water storage tunnel 3 through a ramp connecting tunnel 5.

[0062] The mountain body 2 is located on the convex bank side of the curved section of the river channel 1. 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 correspondingly connected to the two ends of the curved section of the river channel 1. As Figure 1 shown, arranging the river water storage tunnel 3 between the slope connecting tunnel 5 and the river channel 1, and correspondingly connecting the two ends of the river water storage tunnel 3 to the two ends of the curved section of the river channel 1 can reduce the excavation amount of the river water storage tunnel 3 and help reduce the project investment.

[0063] A water retaining dam 6 is provided in the middle of the curved section of the river channel 1. The normal storage 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 storage water level elevation of the water retaining dam 6 is lower than the elevation of the bottom surface of the equipment storage tunnel 4. Ensure that the river water in the reservoir of the water retaining dam 6 can flow naturally into the river water storage tunnel 3, facilitating the diversion of the river water in the river channel 1 into the inner water storage tank 31, but unable to flow naturally into the equipment storage tunnel 4, avoiding the river water entering the equipment storage tunnel 4 and flooding the equipment cabinet 7. In addition, if the maximum storage 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 diverted 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, etc.

[0064] It further includes a power chamber 9 which is arranged in the mountain body 2 and communicated with the equipment storage tunnel 4. A hydroelectric power generation device 61 and a dam reserved passage 62 are arranged in the water retaining dam 6. A pipeline layout passage 35 is arranged at the top inside the river water storage tunnel 3, and the pipeline layout passage 35 is communicated with the dam reserved passage 62. A voltage conversion device 91, a distribution box 92 and a power storage device 93 are arranged in the power chamber 9. The voltage conversion device 91 is electrically connected with the hydroelectric power generation device 61 through a waterproof cable which sequentially passes through the power chamber 9, the equipment storage tunnel 4, the slope connection tunnel 5, the pipeline layout passage 35 and the dam reserved passage 62 at one end. Both the distribution box 92 and the power storage device 93 are electrically connected with the voltage conversion device 91, and the distribution box 92 is electrically connected with the power storage device 93. During use, the hydroelectric power generation device 61 includes a hydroelectric generating set and a step-up transformer, the voltage conversion device 91 is a step-down transformer, and the power storage device 93 includes a rectifier, a storage battery and an inverter. The electricity output by the hydroelectric generating 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 for supplying power to the electrical equipment of the present invention on one hand, and transmitted to the rectifier on the other hand, and stored in the storage battery after being rectified by the rectifier. When the hydroelectric power generation device 61 has a short-term fault, the direct current output by the storage battery is converted into alternating current by the inverter and then transmitted to the distribution box 92 for supplying power to the electrical equipment of the present invention, ensuring the continuous, safe and stable operation of the cave depot type data center. In addition, as Figure 5 shown, the step-up transformer is also externally connected to a power grid line to transmit electricity to other electrical equipment through the power grid line.

[0065] It further includes a road 10 and supporting buildings 11. The road 10 is connected to the end of the equipment storage tunnel 4 far from the river water storage tunnel 3, and the supporting buildings 11 are arranged on one side of the road 10 and are arranged close to the road 10. The supporting buildings 11 include dormitories, canteens and so on.

[0066] A construction method of a green cave depot type data center using hydraulic operation includes the following steps:

[0067] Step 1: Select a river course 1 and a mountain body 2 where the cave depot type data center is to be built, and then build a road 10 and a construction access road. When selecting, it is required that the river water in the river course 1 is relatively abundant throughout the year to meet the heat dissipation and cooling requirements of the data center and the power generation requirements of the hydroelectric power generation device 61. The mountain body 2 should have no major bad geological bodies to ensure construction safety and controllable construction costs, and the size of the mountain body 2 should be appropriate to ensure that the equipment storage tunnel 4 is neither too long nor too short. The length of the mountain body 2 should be controlled between 200m and 500m.

[0068] Step 2: Number all the equipment storage tunnels 4, and then divide the equipment storage tunnels 4 into the first batch and the second batch for construction according to odd and even numbers. When constructing the equipment storage tunnels 4, gradually advance from the side of the road 10 towards the side of the river 1. 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 between adjacent equipment storage tunnels 4 during construction.

[0069] Step 3: After the construction length of the first batch of equipment storage tunnels 4 exceeds 50 meters, start the construction of the second batch of equipment storage tunnels 4. This is to reduce the mutual interference between the first batch of equipment storage tunnels 4 and the second batch of equipment storage tunnels 4 during construction.

[0070] Step 4: After the first batch of equipment storage tunnels 4 is excavated to the designed length, continue to construct the ramp connection tunnel 5 corresponding to the first batch of equipment storage tunnels 4;

[0071] Step 5: Take the already completed first batch of equipment storage tunnels 4 and ramp connection tunnels 5 as construction channels, and carry out the construction of the main body structure of the water storage tunnel 3 in multiple working faces;

[0072] Step 6: After the second batch of equipment storage tunnels 4 is excavated to the designed length and the main body structure of the water storage tunnel 3 is completed, start the construction of the ramp connection tunnel 5 corresponding to the second batch of equipment storage tunnels 4;

[0073] Step 7: After all the ramp connection tunnels 5 are completed, carry out the construction of the auxiliary structures inside the water storage tunnel 3;

[0074] Step 8: Relying on the road 10 and the construction access road, carry out the construction of the water retaining dam 6;

[0075] Step 9: Construct the power tunnel chamber 9 and the supporting building 11, and complete the equipment installation and connection work in the equipment storage tunnels 4, ramp connection tunnels 5, water storage tunnels 3 and water retaining dam 6.

[0076] An operation method of a green cave-type data center using hydraulic operation, including the following steps:

[0077] Step A: Seal both ends of the equipment storage tunnel 4 and fill the equipment storage tunnel 4 with non-combustible gas;

[0078] Step B: Drain the river water in the river 1 into the 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;

[0079] Step C: Start the coolant circulation pump 813 to make the coolant circulate 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;

[0080] 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 into the jacket on the outer wall of the equipment cabinet 7 to cool and dissipate heat from the equipment cabinet 7. 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.

[0081] After the non-combustible gas is filled into the equipment storage tunnel 4, the oxygen concentration inside is lower than 15%. During use, the minimum oxygen concentration for electrical equipment combustion is 15%. The combustion of combustibles is an oxidation process and can only occur above the minimum oxygen concentration. When it is lower than 15%, combustion cannot be maintained and the fire is extinguished.

[0082] Therefore, fill the equipment storage tunnel 4 with harmless non-combustible gases such as nitrogen, and ensure that the oxygen concentration in the equipment storage tunnel 4 is lower than 15%, thereby avoiding fires in the equipment storage tunnel 4. There are usually few staff in the data center. If it is necessary to enter the equipment storage tunnel 4, they can enter after wearing oxygen supply equipment.

[0083] Embodiment 1:

[0084] The IT equipment cabinet 7 of the present invention uses a liquid cooling method for cooling. Compared with the air cooling method, the ventilation demand of the equipment storage tunnel 4 is greatly reduced. To meet the daily air change requirements of the equipment storage tunnel 4, axial fans are installed on the tops of the equipment storage tunnel 4, the slope connection tunnel 5, and the river water storage tunnel 3. As Figure 6 shown, during air change, the air flows longitudinally into the slope connection tunnel 5 along the equipment storage tunnel 4, then longitudinally into the river water storage tunnel 3 along the slope connection tunnel 5, and finally is discharged outside the mountain 2 along the river water storage tunnel 3.
