Description

A kind of communication system outdoor cabinet
Technical field
The invention belongs to the communication equipment technical field, relate to the rack of the outdoor comprehensive distribution of a kind of communication system, be specifically related to the pullable communication system outdoor cabinet of a kind of blower fan.
Background technology
At present, it is a lot of to be used for communication system outdoor cabinet kind, and the type of rack is different and different with function because of the purposes of the inner communication equipment of installing of rack.The radiating mode of rack is divided into air conditioner type, fan is forced air-exhaust type and natural ventilation type etc.Fan forces that air-exhaust type is simple in structure, cost is low, good heat dissipation effect and extensively being adopted.Rack is installed the occasion major part and is chosen in outdoor installation, can receive the radiation of the sun inevitably, adds the heat that communication equipment produces in the rack, can make the rack internal temperature under the air-tight state too high.The inner too high temperature of rack can influence the operate as normal and the useful life of communication equipment, so the air discharging and radiating performance of rack is very important to the rack serviceability.The cooling machine cabinet mode is: the air channel of cabinet or ventilating opening are the inner and ambient atmosphere environment passages of rack, and rack is provided with automatic temperature control switch and blower fan, when the rack internal temperature reaches design temperature (generally setting 45 ℃); Temperature detect switch (TDS) is closed; Blower fan is started working, and the high temperature air that rack is inner is forced to discharge, the inner negative pressure that produces of rack; Extraneous cold air is inhaled into rack inside through the air channel, reaches the cooling purpose.Can the performance of ventilating of blower fan and state are directly connected to communication equipment operate as normal, and summer temp is high, and blower fan is in normal start operating state, breaks down easily, need often clean, keep in repair or ventilating fan more.The blower fan installation position of prior art rack and mounting means are unfavorable under the communication equipment running status, changing; Safeguard or more need earlier communication equipment is shut down during ventilating fan; Remove the rack intercom set, just can safeguard or change operation, influence the normal operation of communication system.
Summary of the invention
For overcoming the deficiency of above-mentioned prior art, the present invention provides a kind of communication system outdoor cabinet, makes blower fan under the situation that does not influence the normal operation of communication equipment, safeguard and change, and improves the serviceability of rack.
Communication system outdoor cabinet of the present invention comprises cabinet, cabinet door and fan unit.Fan unit comprises machine frame, blower fan pallet, blower fan dust cover and 1~5 typhoon machine, and machine frame is fixedly mounted on the top of rack, and chute is equipped with in the bottom of machine frame.The blower fan pallet is the drawer-like structure, and blower fan is installed on the tray substrate of blower fan pallet, and blower fan pallet bottom is provided with slide rail, and the blower fan pallet links to each other through slideway with machine frame, and the blower fan pallet can be extracted out from machine frame or push.The upper and lower wind direction position that blower fan is corresponding is provided with the wind hole, the diameter in wind hole and the equal diameters of fan leaf, and protection network is equipped with at place, wind hole, and the blower fan dust cover is positioned at the top of air outlet on the blower fan.
The connecting portion of blower fan and blower fan pallet posts rubber cushion, is used to slow down the noise that fan vibration produces.Blower fan is in-line in the blower fan pallet arranges, and does not get rid of other arrangement mode.Protection network is a metal wire structure, and the protection network of other material also is protection scope of the present invention.After the integral installation of blower fan pallet put in place, the blower fan pallet did not take off screw with pine and is fixed on the machine frame.The blower fan dust cover is provided with ventilation window, and ventilation window is provided with the aluminium foil cover plate.Aluminium foil cover plate and ventilation window are through the hinged installation of rivet, but the aluminium foil cover plate is an open and-shut mode.
The present invention is through being installed in blower fan in the drawer type blower fan pallet; The blower fan pallet is connected through slideway with machine frame, when needing replacing or safeguarding blower fan, operation is safeguarded or changed in the extraction of blower fan pallet; After the completion blower fan pallet is pushed machine frame; Do not take off screw with pine and fix, realized under the communication equipment running status or do not influenced in the rack carrying out the blower fan maintenance, safeguard and more changing jobs under the normal situation about moving of communication equipment, improved the serviceability of rack.Fan unit is installed in the top of rack, and air draft is effective, and the space that takies rack is little, does not influence the installation and the use of communication equipment in the rack.The connecting portion of blower fan and blower fan pallet posts rubber cushion, can slow down the noise that fan vibration produces, and helps reducing the noise pollution of blower fan to surrounding environment.The blower fan dust cover that can open and close plays the dustproof effect, reduces and avoids dust to get into blower fan and rack.
