Fan unit

The present invention relates to a fan unit, and more particularly to a fan unit suitable for use in an electronic device.

The server is the core computer that serves each computer in the network system. It can provide the functions of the disk and printing services required by the network users, and also allows each client to share 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 consists of a central processing unit (CPU), a memory, and an input/output (I/O) device, and is connected by a bus. It is connected internally, connected to the central processing unit and memory through the north bridge chip, and connected to the input/output device through the south bridge chip. The server has undergone three evolutions in terms of chassis architecture: from early tower chassis to rack servers that emphasize centralized performance to high-density computing.

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

The dimensions of the cabinets are also based on common industry standards, usually ranging from 22U to 42U. The height of the U in the cabinet has a detachable sliding trailer. Users can flexibly adjust the height according to the elevation of their own servers to store network devices such as servers, hubs, and disk array cabinets. After the server is placed, all its I/O lines are taken out from the rear of the cabinet (all interfaces of the rack server are also at the rear), and are uniformly placed in the trunking of the cabinet, generally labeled with labels for easy management.

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

The present invention provides a fan unit that facilitates disassembly and maintenance independently.

The invention provides a fan unit suitable for use in an electronic device. The electronic device includes a fan tray. The fan frame has a first connector.
