[0002] As science and technology advance towards the information age of rapid development, the huge amount of data information generated by the communication equipment we use every day needs to be processed by the server. In order to facilitate the management and maintenance of the server, it is usually necessary to build an independent data room for the storage of the server and act as a data center. At present, most data rooms are placed in a fixed space. For example, companies or units usually use the method of building walls to build a room specifically for placing servers. During the construction process, all the required equipment needs to be purchased and transported back to the location where the data room is built, and then the subsequent assembly and construction work is carried out. However, during the transportation process, all the equipment needs to be packed and transported, and then unpacked after transportation, and finally assembled and built. The whole process is cumbersome, and the entire construction cycle is relatively long, which seriously affects the start-up efficiency of the project. Therefore, further improvements can be made.

[0003] At present, a Chinese patent with the authorization announcement number CN118250981B discloses a container-type data center, including a data container body, a computer module, a control center and a heat dissipation system. The heat dissipation system includes a circulating water circuit, a fin-tube heat exchanger and a heat dissipation fan. The data container body and the heat dissipation container rack are stacked. The fin-tube heat exchanger and the heat dissipation fan are both installed in the heat dissipation container rack. The circulating water circuit is arranged in the data container body and cooperates with the fin-tube heat exchanger and the heat dissipation fan to water-cool the computer modules on the shelf. At the same time, the use of the data container body, the heat dissipation container rack and the stacked arrangement structure of the two to form a modular construction method not only significantly shortens the installation time, thereby speeding up the entire process from the equipment being in place to being put into operation, but also greatly improves the startup efficiency of the project.
