The invention relates to a server cabinet.

With the development of information technology, the knowledge economy is exploding. For the storage and computing data needs, various data storage and computing centers are established in large numbers. When multiple servers are simultaneously loaded into a server cabinet, it not only saves space and It is easy to manage, and it can make multiple servers work together to execute large computing projects. Therefore, the server cabinet is widely used in building data storage and computing centers. The appearance of the server is usually designed according to the unified standard. Its height is U (1U = 1.75 inches = 44.45 mm), including 1U, 2U, 3U, 4U, 5U, 6U, 7U and other standards, so the server The dimensions of the cabinet are also based on common industry standards.

Generally, the server cabinet has a rectangular shape, and includes a top plate, a bottom plate, and four side plates respectively connected between the top plate and the bottom plate. The top plate, the bottom plate and the side plates are collectively arranged to form a space for storing network devices such as a server, a hub, and a disk array cabinet. The plurality of servos are respectively arranged on the left and right side plates in the axial direction, and each of the servers is provided with a plurality of suction fans. A plurality of perforations are formed on the front and rear side plates of the server cabinet. In use, the aspirating fan operates so that the cooling airflow is blown from the front of the server cabinet through the perforations on the front side panel to the server to carry away the heat generated by the server, forming a high temperature airflow flowing out from the perforations on the rear side panel of the server cabinet. .

However, in order to make the server cabinet easy to provide good function scalability and ease of assembly, the height of the server cabinet design is usually greater than the sum of the heights of a certain number of servers when the server is mounted on the servo. After the cabinet is installed, a certain height interval is usually formed between the uppermost server and the top plate of the cabinet. The height of this gap in some server cabinets is even greater than 1U. Due to the existence of the interval, a part of the high-temperature airflow which should originally flow from the perforation on the rear side panel of the server cabinet is returned from the interval to the front of the server, and the temperature of the airflow in front of the server rises as the usage time increases. The high temperature causes the internal temperature of the server cabinet to rise, which affects the efficiency of the internal and external airflow exchanges in the server cabinet. As a result, a large amount of heat accumulates in the server cabinet, and even the server is overheated and stops running.

In view of this, it is necessary to provide a server cabinet that facilitates heat dissipation of a server installed therein.
