[0024] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0025] like Figures 1 to 5 As shown, this utility model discloses a ventilation hub chamber 2 suitable for a cavern-type data center. The ventilation hub chamber 2 is located within a mountain 1 and includes a chamber support structure 21 and a ventilation duct 24. The chamber support structure 21 is ellipsoidal, and the ventilation duct 24 is located inside the chamber support structure 21. Because the ventilation hub chamber 2 is located within the mountain 1, and its chamber support structure 21 is ellipsoidal, when multiple data tunnels 5 are arranged within the mountain 1, one end of each data tunnel 5 can be connected to the ventilation hub chamber 2, while the other end extends and radiates in different directions from the ventilation hub chamber 2 until it connects to the surface of the mountain 1. The air and smoke that need to be discharged from the data tunnels 5 enter the ventilation hub chamber 2, are collected by the ventilation duct 24, and transported to the exhaust shaft 4 for discharge to the top of the mountain 1. Therefore, it can be seen that the ventilation hub chamber 2 connects multiple data tunnels 5 without penetrating the mountain 1, and its excavation volume is small, which can reduce the engineering investment of the cavern-type data center. After the ventilation hub chamber 2 collects the air and smoke that need to be discharged from multiple data tunnels 5, it is then uniformly transported to the exhaust shaft 4 and discharged to the top of the mountain 1. One exhaust shaft 4 can meet the exhaust needs of multiple data tunnels 5, which helps to reduce the number of exhaust shafts 4 to be built, thereby achieving the goal of reducing the engineering investment of the cavern-type data center.

[0026] The cavern support structure 21 includes an initial support layer 211 and a secondary lining layer located inside the initial support layer 211. The initial support layer 211 is an elliptical spherical steel arch frame structure. The secondary lining layer inside the initial support layer 211 serves as a permanent support to ensure the structural stability of the ventilation hub cavern 2.

[0027] The top of the inner side of the cavern support structure 21 is provided with an equipment compartment 22, and the bottom of the inner side of the cavern support structure 21 is provided with a fire extinguishing gas storage compartment 23.

[0028] The fire extinguishing gas storage chamber 23 contains a non-flammable gas, which may be nitrogen, argon, or a mixture of IG541 gases. In the event of a fire in the data tunnel 5, the non-flammable gas stored in the fire extinguishing gas storage chamber 23 can be supplied to the data tunnel 5 to reduce the oxygen content in the data tunnel 5 and achieve the purpose of extinguishing the fire.

[0029] The mountain 1 is also provided with a gas supplement pipeline, one end of which is connected with the fire extinguishing gas storage bin 23, and the other end extends outside the mountain 1, and the end is provided with a gas pipeline switch. In use, the gas supplement pipeline is used as a supplement pipeline for the non-combustible gas in the fire extinguishing gas storage bin 23.

[0030] The lower end of the air guide pipe 24 is connected with the top plate of the fire extinguishing gas storage bin 23, and the upper end extends into the equipment bin 22.

[0031] A plurality of air inlets 241 are arranged on the air guide pipe 24 in a circumferential direction, the air inlets 241 are located between the equipment bin 22 and the fire extinguishing gas storage bin 23, and air doors are arranged at the air inlets 241. In use, the opening and closing of the air inlets 241 are controlled by the air doors, and the wind or smoke entering the cavern support structure 21 from the data tunnel 5 enters the air guide pipe 24 through the air inlets 241.

[0032] The shape and size of the outer wall of the air guide pipe 24 between the top of the air inlet 241 and the fire extinguishing gas storage bin 23 gradually expand from top to bottom. The wind flow discharged from the data tunnel 5 is smoothly guided into the air guide pipe 24 through the outer wall of the air guide pipe 24, and the axial flow fan 3 can quickly suck and guide the wind discharged from the data tunnel 5 into the air guide pipe 24.

[0033] The upper end of the air guide pipe 24 is provided with an axial flow fan 3, and the axial flow fan 3 is located on the inner side of the cavern support structure 21. In use, the axial flow fan 3 provides power for the air guide pipe 24 to discharge air, so as to accelerate the wind speed in the air guide pipe 24 and improve the air discharge efficiency.
