Description

Technical Field

[0001] This utility model relates to a data tunnel structure for a cavern-type data center, belonging to the technical field of cavern-type data centers. Background Technology

[0002] Because they are entirely buried underground, cavern-style data centers possess typical advantages such as high security, high concealment, high protection, and high energy efficiency, thus becoming a major new direction in data center development. However, considering the relatively enclosed structure of cavern-style data centers, it is necessary to focus on studying the ventilation requirements of their core component, the data tunnel, during daily operation.

[0003] Chinese patent document CN116648044A discloses an explosion-proof horizontal ventilation system suitable for cavern-type data centers. In this system, the temperature and humidity inside the data center cavern are regulated through a fresh air supply subsystem to meet the daily ventilation needs of the data center cavern.

[0004] However, since the fresh air supply subsystem is independent of the data center cavern and is buried underground or set up in the mountain in the form of a tunnel, it will not only increase the amount of excavation for the cavern-type data center and increase the project investment, but also be detrimental to the heat dissipation of the fresh air supply subsystem. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a data tunnel structure for a cavern-type data center.

[0006] This utility model is achieved through the following technical solution:

[0007] A data tunnel structure for a cavern-type data center includes a mountain and a data cavern located within the mountain. One end of the data cavern is connected to the surface of the mountain. The top of the interior of the data cavern is provided with an upper air duct, and the bottom is provided with a lower air duct. The middle parts of both the upper and lower air ducts are connected to the interior of the data cavern. An air conditioning temperature control room is provided at the end of the data cavern that is connected to the mountain surface. An air conditioning unit is provided in the air conditioning temperature control room. One end of the upper air duct is connected to the air conditioning unit, and this end is provided with an external end pipe switch A and an exhaust fan A. One end of the lower air duct is connected to the air conditioning unit, and this end is provided with an external end pipe switch B and an exhaust fan A.

[0008] The upper air duct is equipped with an inner end pipe switch A and a suction fan B at the end away from the suction fan A.

[0009] The lower air duct is equipped with an inner end pipe switch B and an exhaust fan B at the end away from the exhaust fan A.

[0010] The data cavern is equipped with side air ducts on both the left and right sides. One end of the side air duct is connected to the outside of the mountain and is equipped with an external end pipe switch C and an air filter. The other end terminates at the end face of the data cavern, and the middle part of the side air duct is connected to the inside of the data cavern.

[0011] The data cavern also includes an equipment storage room, and both the equipment storage room and the air conditioning temperature control room are located within the space enclosed by the upper air duct, the lower air duct, and the side air duct.

[0012] The upper air duct, lower air duct, and side air duct are all provided with multiple ventilation holes for connecting to the equipment storage room.

[0013] The equipment storage room is equipped with IT equipment.

[0014] The equipment storage room has two rows of IT equipment, with an aisle between the two rows of IT equipment.

Detailed Implementation

[0023] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0024] like Figures 1 to 4 As shown in the figure, the present invention discloses a data tunnel structure for a cavern-type data center, comprising a mountain body 8 and a data cavern 1 located within the mountain body 8. One end of the data cavern 1 is connected to the surface of the mountain body 8. An upper air duct 13 is provided at the top of the inner side of the data cavern 1, and a lower air duct 17 is provided at the bottom. The middle parts of both the upper and lower air ducts 13 and 17 are connected to the interior of the data cavern 1. An air conditioning temperature control chamber 11 is located at the end of the data cavern 1 that is connected to the surface of the mountain body 8. An air conditioning unit is installed in the air conditioning temperature control chamber 11. One end of the upper air duct 13 is connected to the air conditioning unit, and this end is equipped with an external end pipe switch A and an exhaust fan A131. One end of the lower air duct 17 is connected to the air conditioning unit, and this end is equipped with an external end pipe switch B and an exhaust fan A171. In use, the air conditioning unit adopts a data center-specific constant temperature and humidity air conditioner. Figure 3 As shown, when the data tunnel is operating in temperature control mode, the air conditioning unit in the air conditioning control room 11 is started, the outer end pipe switch A and the suction fan A131 of the upper air duct 13 are opened, and the outer end pipe switch B and the exhaust fan A171 of the lower air duct 17 are opened. The hot air in the upper air duct 13 enters the air conditioning unit, is cooled by the air conditioning unit to form cold air, and the cold air is sent into the data tunnel 1 through the lower air duct 17. Then, it carries away the heat generated by the equipment in the data tunnel 1 and forms hot air that enters the upper air duct 13. This cycle repeats to achieve the purpose of temperature and humidity control inside the data tunnel 1.

[0025] Integrating the upper air duct 13, lower air duct 17, and air conditioning control room 11 into the data cavern 1 reduces the amount of excavation required for the cavern-type data center and lowers project investment. Furthermore, placing the air conditioning control room 11 at the end of the data cavern 1 that connects to the surface of the mountain 8 facilitates heat dissipation for the air conditioning unit.

[0026] The upper air duct 13 is equipped with an inner end pipe switch A and a suction fan B132 at the end away from the suction fan A131.

[0027] The lower air duct 17 is equipped with an inner end pipe switch B and an exhaust fan B172 at the end away from the exhaust fan A171.

[0028] The data cavern 1 is equipped with side air ducts 14 on both the left and right sides. One end of the side air duct 14 connects to the outside of the mountain 8, and this end is equipped with an external end pipe switch C and an air filter. The other end terminates at the end face of the data cavern 1, and the middle part of the side air duct 14 connects to the interior of the data cavern 1. In use, an air filter is installed at the end of the side air duct 14 that connects to the outside of the mountain 8 to filter out dust and other particles in the air entering the data cavern 1 and adjust the air humidity to the range required by the data center.

[0029] The data cavern 1 also includes an equipment storage room 12, and the equipment storage room 12 and the air conditioning temperature control room 11 are both located within the space enclosed by the upper air duct 13, the lower air duct 17 and the side air duct 14.

[0030] The upper air duct 13, lower air duct 17 and side air duct 14 are all provided with multiple ventilation holes for communicating with the equipment storage room 12.

[0031] The equipment storage room 12 is equipped with IT equipment.

[0032] The equipment storage room 12 is equipped with two rows of IT equipment, with an aisle 16 between them. The aisle 16 is positioned between the two rows of IT equipment to facilitate the passage of staff.

[0033] A fireproof isolation door is provided between the air conditioning temperature control room 11 and the equipment storage room 12.

[0034] An explosion-proof isolation door is installed at one end of the data cavern 1 near the air conditioning temperature control room 11.

[0035] Specifically, the mountain body 8 is also equipped with a ventilation hub chamber 2 and an exhaust shaft 3. The lower end of the exhaust shaft 3 is connected to the ventilation hub chamber 2, and the upper end is connected to the top of the mountain body 8.

[0036] The ventilation hub cavern 2 includes a cavern support structure 21, a gas supply pipeline, and a duct 24. An equipment compartment 22 is located at the top inner side of the cavern support structure 21, and a fire extinguishing gas storage compartment 23 is located at the bottom inner side of the cavern support structure 21. One end of the gas supply pipeline is connected to the fire extinguishing gas storage compartment 23, and the other end extends outside the mountain 8, with a gas pipeline switch at that end. The duct 24 is located inside the cavern support structure 21, with its lower end connected to the top plate of the fire extinguishing gas storage compartment 23 and its upper end extending into the equipment compartment 22. The gas supply pipeline serves as a supply pipeline for non-flammable gas within the fire extinguishing gas storage compartment 23. The fire extinguishing gas storage compartment 23 contains non-flammable gas, which is nitrogen, argon, or an IG541 mixture.

[0037] Multiple air inlets 241 are evenly distributed in the circumferential direction on the air duct 24. The air inlets 241 are located between the equipment compartment 22 and the fire extinguishing gas storage compartment 23, and air dampers are provided at the air inlets 241.

[0038] The lower part of the exhaust shaft 3 is connected to the top of the cavern support structure 21, and the lower end of the exhaust shaft 3 extends into the equipment compartment 22, and is connected to the upper end of the air duct 24 through the axial flow fan 7. The axial flow fan 7 provides power for the exhaust of the exhaust shaft 3 to accelerate the internal airflow and improve its exhaust efficiency.

[0039] One end of the upper air duct 13, equipped with a suction fan B132, is connected to the air duct 24 via a ventilation pipe 5. The end of the data chamber 1 furthest from the air conditioning control room 11 is connected to the chamber support structure 21 via a ventilation cross passage 4. The connection between the ventilation cross passage 4 and the chamber support structure 21 is located between the equipment compartment 22 and the fire extinguishing gas storage compartment 23. Both ends of the ventilation cross passage 4 are equipped with fireproof isolation doors. One end of the lower air duct 17, equipped with an exhaust fan B172, is connected to the fire extinguishing gas storage compartment 23 via a concealed pipe 6.

[0040] like Figure 1 As described above, when the data tunnel is operating in ventilation mode, the outer end pipe switch C, the fireproof isolation doors at both ends of the ventilation cross passage 4, and the axial flow fan 7 are opened. Air from outside the mountain body 8 flows through the air filter and enters the side air duct 14, then diffuses into the equipment storage room 12. Next, it enters the ventilation hub chamber 2 through the ventilation cross passage 4, and finally is discharged to the top of the mountain body 8 through the air guide pipe 24 and the exhaust shaft 3, thus replacing the air inside the equipment storage room 12. The equipment storage room 12 uses the end of the side air duct 14 connected to the mountain body 8 as an air inlet, and simultaneously utilizes the ventilation hub chamber 2 and the exhaust shaft 3 to exhaust the air inside, thereby achieving air replacement within the equipment storage room 12.

[0041] like Figure 2As shown, when the data tunnel 1 is in fire exhaust mode, first open the inner end pipe switch B and exhaust fan B172 at one end of the lower air duct 17, and close the outer end pipe switch B and exhaust fan A171 at the other end of the lower air duct 17.

[0042] The non-flammable gas in the fire extinguishing gas storage chamber 23 enters the lower air duct 17 through the buried pipe 6, and then enters the equipment storage room 12 from the lower air duct 17 to extinguish the fire. Next, the inner end pipe switch A and the suction fan B132 at one end of the upper air duct 13 are opened, and the outer end pipe switch A and the suction fan A131 at the other end of the upper air duct 13 are closed. The axial flow fan 7 is then started. The smoke generated during the fire extinguishing process flows sequentially through the upper air duct 13 and the ventilation pipe 5 before entering the air guide pipe 24, and finally is discharged to the top of the mountain 8 through the exhaust shaft 3. The non-flammable gas in the fire extinguishing gas storage chamber 23 enters the lower air duct 17 through the buried pipe 6, and then enters the equipment storage room 12 from the lower air duct 17 to reduce the oxygen content in the air in the equipment storage room 12, thereby achieving the purpose of fire extinguishing. When the lower air duct 17 is in operating temperature control mode and fire smoke exhaust mode, the airflow direction inside it is inconsistent. The airflow direction is controlled by the exhaust fans A171 and B172 at both ends.
