technical field

The invention relates to a fan rack, in particular to a fan rack suitable for server racks.

Background technique

The server is the core computer serving each computer in the network system. It can provide functions such as disk and printing services required by network users, and also allows each client to share various resources in the network environment with each other. The basic structure of the server is roughly the same as that of a general personal computer. It is composed of a central processing unit (CPU), a memory (Memory) and an input/output (I/O) device, and is internally connected by a bus (Bus). Connected, the central processing unit and the memory are connected through the north bridge chip, and the input/output devices are connected through the south bridge chip. According to the structure of the chassis, the server has gone through three evolutionary processes: from the early tower chassis to the rack type that emphasizes centralized performance, and then to the blade server with high-density computing.

Here, a rack server is taken as an example. A rack server is a server whose appearance is designed according to a uniform standard and used in conjunction with a cabinet. It can be said that the rack type is a tower server with an optimized structure, and its design purpose is mainly to reduce the server space occupation as much as possible. Many professional network devices are rack-mounted, and most of them are flat, just like drawers. Such as switches, routers, hardware firewalls, etc. The width of the rack server is 19 inches, and the height is in U (1U = 1.75 inches = 44.45 mm). There are usually several standard servers of 1U, 2U, 3U, 4U, 5U, and 7U.

The size of the cabinet is also a common industry standard, usually ranging from 22U to 42U. There are detachable sliding brackets in the cabinet according to the height of U. Users can flexibly adjust the height according to the height of their own servers to store network equipment such as servers, hubs, and disk array cabinets. After the server is placed, all its I/O lines are drawn from the rear of the cabinet (all interfaces of the rack server are also at the rear), and are uniformly placed in the wire slots of the cabinet, usually with labels for easy management.

Generally speaking, the plurality of fans of the existing rack server are not independently assembled in the rack, so that each fan is inconvenient to be disassembled and repaired quickly. In addition, the multiple fans of the existing rack server are not independently electrically connected to the rack, and cannot be hot-swapped independently. Therefore, it is inconvenient to stop all the fans when performing maintenance on a single fan.
