Exhaust shaft suitable for cave depot type data center

Abstract

The utility model discloses an exhaust shaft suitable for a cave depot type data center, and belongs to the technical field of cave depot type data centers. The exhaust shaft is arranged in a mountain and comprises a centralized air duct section and a distributed exhaust structure, and the distributed exhaust structure is connected with the upper end of the centralized air duct section and communicated with the top of the mountain. Due to the fact that the multiple air outlets are formed in the top of the mountain body of the distributed air exhaust structure, when part of the air outlets are struck to be damaged and blocked, the remaining air outlets can still operate normally to conduct air exhaust and smoke exhaust, and therefore the anti-striking capacity and survivability of the air exhaust vertical shaft can be further improved through the distributed air exhaust structure.

Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of exhaust shaft suitable for cave-type data center, belong to cave-type data center technical field. BACKGROUND

[0002] Because overall bury in underground, cave-type data center has the typical advantage of high security, high concealment, high protection, high energy efficiency, and then become a new direction of data center development. However, considering the relative closedness of cave-type data center structure, it is necessary to study its ventilation and smoke exhaust demand in fire accident in daily operation state, and cave-type data center usually uses ventilation system or exhaust system for ventilation and smoke exhaust.

[0003] For example, the Chinese patent document with publication number CN118292682A discloses a cave-type data center combined ecological building group, which includes a longitudinal connecting channel and horizontal data center caverns arranged in order on both sides of the longitudinal connecting channel. A roof building is provided above the horizontal data center caverns, and the horizontal data center caverns are connected to the roof building through a zigzag ventilation shaft. By excavating a foundation pit near the ground of the roof, a structural corner is added to the upper end of the ventilation shaft using the foundation pit, and the vertical shaft structure above ground is integrated into the structure as a column, which can effectively increase the impact resistance of the ventilation shaft.

[0004] The zigzag ventilation shaft in the above-mentioned patent improves the impact resistance by adding a structural corner to its upper end. However, the zigzag ventilation shaft uses a single air outlet structure, and when the air outlet is damaged by impact, it may cause the zigzag ventilation shaft to be blocked and lose its function, so its impact resistance needs to be further improved. UTILITY MODEL CONTENTS

[0005] To solve the above technical problems, the utility model provides an exhaust shaft suitable for cave-type data center.

[0006] The utility model is realized by the following technical solutions:

[0007] An exhaust shaft suitable for cave-type data center is provided, which is arranged in a mountain. The exhaust shaft includes a centralized air duct section and a decentralized exhaust structure. The decentralized exhaust structure is connected to the upper end of the centralized air duct section and communicates with the top of the mountain.

[0008] The lower end of the centralized air duct section is provided with an axial flow fan.

[0009] The distributed exhaust structure comprises an explosion-proof plate, a backfill cover layer and a plurality of zigzag air ducts, the explosion-proof plate is arranged in the mountain and located directly above the centralized air duct section, the backfill cover layer is arranged on the explosion-proof plate, one end of each of the plurality of zigzag air ducts is communicated with the upper end of the centralized air duct section, and the other end is exposed on the top of the mountain as an exhaust outlet.

[0010] The exhaust outlets of the plurality of zigzag air ducts are irregularly distributed around the centralized air duct section.

[0011] The explosion-proof plate is buried in the mountain with a depth of not less than 5m.

[0012] Trees are planted around the zigzag air ducts on the top of the mountain.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. Since the distributed exhaust structure has a plurality of exhaust outlets on the top of the mountain, when some of the exhaust outlets are damaged and blocked by impact, the remaining exhaust outlets can still normally operate to exhaust air and smoke, so it can be seen that the distributed exhaust structure can further improve the anti-impact ability and survival ability of the exhaust shaft.

[0015] 2. Compared with the arrangement mode that all the exhaust outlets of the zigzag air ducts are regularly distributed around the centralized air duct section, the arrangement mode that all the exhaust outlets of the zigzag air ducts are irregularly distributed around the centralized air duct section can further improve the survival ability of the exhaust outlets of the zigzag air ducts in the distributed exhaust structure.

[0019] The technical scheme of the utility model will be further described below, but the scope of protection is not limited to the description.

[0020] For example, Figure 1 and Figure 2The utility model discloses a kind of exhaust shafts suitable for cave-type data center, the exhaust shaft 2 is located in mountain 1, the exhaust shaft 2 includes centralized air duct section 21 and dispersed exhaust structure 22, the dispersed exhaust structure 22 is connected with the upper end of centralized air duct section 21, and is communicated with the top of mountain 1.In use, the data tunnel of cave-type data center is transported to centralized air duct section 21 with the wind and smoke needed to discharge, then the wind and smoke in centralized air duct section 21 are discharged to the top of mountain 1 by dispersed exhaust structure 22, since there are multiple air outlets on the top of mountain 1 for dispersed exhaust structure 22, when part of air outlet is damaged and blocked by attack, the remaining air outlet can still operate normally to discharge wind and smoke, so it can be seen that the use of dispersed exhaust structure 22 can further improve the anti-attack ability and survivability of exhaust shaft 2.

[0021] The lower end of the centralized air duct section 21 is provided with an axial flow fan 3.In use, the axial flow fan 3 provides power for the exhaust of the exhaust shaft 2 to accelerate the wind speed inside and improve the exhaust efficiency.
