The cabinets look almost the same, but there are still several types. The common ones are the cabinet for wiring and the cabinet for placing servers. The cabinet used for wiring is generally used to place multiple terminal switches, so there will be a lot of network cables to be connected out. This kind of cabinet is inconvenient to set doors and looks more like a rack. Some cabinet manufacturers call this product wiring rack; The cabinet used to place servers must have doors and locks. Expensive routers and firewalls are generally placed in this cabinet.
An ordinary server cabinet has four cooling fans, which are installed on the top of the cabinet, and the bottom of the cabinet is hollowed out, so as to provide a good constant temperature environment for the interior of the cabinet. The cooling effect of the server at the top of the cabinet is very good, but the cooling effect of the server in the middle and lower part is not ideal. The high-end server cabinet can be ventilated and dissipated through the dense air holes on the front and rear doors. It can even be distributed around each server in the cabinet by expanding the accessories of the built-in air conditioner, which has high requirements for the material, anti-corrosion, anti rust and load-bearing capacity of the cabinet.
