## Abstract

A data center system includes an infrastructure unit including a public area and a bridge area and at least one computer room. The computer room is disposed along an extending direction of the bridge area, and a length of the bridge area is matched with a length of computer rooms arranged along the bridge area, so that a number of computer rooms may be increased according to the needs. The computer room includes a plurality of layers of data centers stacked on each other. Cold passage areas and hot passage areas of two neighboring layers of data centers form a cold air passage and a hot air passage so that cold air produced by a cooling module may be directed to each data center, and hot air in each data center may be directed to the cooling module to enable devices in each data center to operate under appropriate temperature.

## Claims

### Claim 1

A first data center comprising:
a main computer room area including a separation plate having an opening, the separation plate being disposed along a horizontal direction of the main computer room area separating the main computer room area into an accommodation space at a lower layer and an air exhaust passage at an upper layer, the accommodation space being connected with the air exhaust passage through the opening;
a cold passage area disposed on a side of the main computer room area, the cold passage area being connected with the accommodation space;
a hot passage area disposed on another side of the main computer room area, the hot passage area being connected with the air exhaust passage and isolated from the cold passage area; and
a plurality of hollow structures corresponding to the cold passage area and the hot passage area respectively.

### Claim 2

A data center system comprising:
an infrastructure unit including a public area and a bridge area, a side of the bridge area being connected with the public area, another side of the bridge area extending toward a direction away from the public area; and
at least one computer room disposed along a extending direction of the bridge area and connected with the bridge area, the computer room comprising a plurality of layers of data centers, each layer of the plurality of layers of data centers comprising:
a main computer room area including a separation plate having an opening, the separation plate being disposed along a horizontal direction of the main computer room area separating the main computer room area into an accommodation space at a lower layer and an air exhaust passage at an upper layer, the accommodation space being connected with the air exhaust passage through the opening;
a cold passage area disposed on a side of the main computer room area, the cold passage area being connected with the accommodation space;
a hot passage area disposed on another side of the main computer room area, the hot passage area being connected with the air exhaust passage and isolated from the cold passage area; and
a plurality of hollow structures corresponding to the cold passage area and the hot passage area respectively,
wherein:
the cold passage areas of two neighboring layers of data centers are in connection with each other through a corresponding hollow structure of the plurality of hollow structures, which forms a cold air passage running through the plurality of layers of data centers in the computer room; and
the hot passage areas of two neighboring layers of data centers are in connection with each other through another corresponding hollow structure of the plurality of hollow structures, which forms a hot air passage running through the plurality of layers of data centers in the computer room, and
a length of the bridge area is matched with a length of the at least one computer room arranged along the bridge area.
