Description
Technical field
The present invention relates to a kind of equipment cabinets, it has the air cooling system for apparatus cools being arranged in cabinet inside volume.
Background technology
Normally work and safety in order to ensure electronic equipment, especially those electronic equipments be arranged in outdoor environment, this equipment is installed in cabinet usually.This cabinet is used in telecommunications application usually, such as mobile communication base station and switching equipment, and also in other outdoor utility, such as electronic equipment needs to apply with other street furnitures at the traffic signalization case of outside work.The design of this equipment cabinets needs to adapt to the environment that this equipment is installed.
Because electronic equipment operationally inevitably produces heat, a kind of approach is therefore needed this heat to be discharged from cabinet.This has come with cooling device through cabinet by controlling air stream usually.Can flow directly in cabinet by making air stream and flow out cabinet and flow through cooling around this equipment, also indirectly can carry out, such as, pass through heat exchanger.Can also conditioner be used, but this significantly increases the volume of equipment cabinets and total cost and operating cost, therefore avoid when avoiding as far as possible.
GB2333185 discloses polytype base station apparatus, and wherein mobile telephone equipment is arranged in the cabinet of street corner building article form.Enter cabinet by ordering about air to make it pass inlet grid and make hot-air pass outlet cells or other openings and flow out the external realization cooling of cabinet.
GB2354066 discloses a kind of cabinet with heat-sink unit, and it comprises the support for installing electronic equipment, also comprises fan unit, arrives exhaust chamber discharge for ordering about air from plenum chamber through this equipment.Machine box door provides filter, and air is driven in cabinet by this filter.
The focus of said system is concentrated and is that pressure Air flow is carried out in equipment cabinets inside.The particular problem relevant to existing system is the air bells laid of the particulate matter entering cabinet, such as earth and dust, and these particulate matters can affect the operation of internal unit.Therefore generally use air cleaner, this filter is arranged to extract air bells laid particulate matter at least partially before air bells laid particulate matter arrives the equipment of cabinet inside.But use air cleaner can inevitably occur potential blockage problem, the air stream caused through cabinet reduces by this problem, consequently reduce the working temperature rising of cooling effectiveness, equipment.In extreme situations, plugged sereen will cause equipment to exceed safe working temperature, and this will cause this equipment automatically to close to prevent any damage or fault.This can cause loss of service, and needs calling engineer to keep in repair this equipment and to change arbitrary plugged sereen.Therefore, in order to reduce equipment fault or inefficacy, can under wider condition of work scope, keep cooling effectiveness to be very important as far as possible for a long time, as far as possible.
US 2001/0052412 A1 solves the problem of plugged filter by using air-air heat exchanger, the internal capacity that this air-air heat exchanger makes equipment install and external environment condition isolated.Do not provide the extreme case of enough cooling at heat exchanger under, the second cooling system is started working, and to impel air directly through internal container, this second cooling system has filter on air intake, enters to prevent Air settlement matter.But this solution partly can only solve the problem of blocking, because still need plugged sereen the most at last.In addition, the cooling that heat exchanger can provide is subject to the restriction of the required temperature difference.
WO 2009/090405 discloses a kind of air cleaner, comprise feed tube, this feed tube is formed in the passage extended between the entrance and exit of air cleaner, and comprise the seta (bristle) extended at least partially crossing passage from carrier wall, to remove from through in the air of this feed tube the particle carried secretly.Such filter combines seta, substitutes traditional foam filter element with seta, can reduce and eliminate the blocking of filter in some cases.This heat and be particularly useful in environment dusty, air bells laid particle makes air stream normally work in such a case.But, in order to make filter work expeditiously, needing larger entrance section to amass, to reduce the speed of intake air stream, reaching the level that entrained particles is captured by the seta of filter.Be in the application of the form of street furniture in equipment cabinets, do not select the external filter unit of large volume, because the occupy-place size of cabinet can be very restricted, such as, be subject to the restriction of local planning requirement.
Another problem of street corner Application in Building is intentional destruction; it causes the conflict of two aspects below: require on the one hand to guarantee that equipment safe enough in cabinet is to prevent damaged (burst accident or other), and guarantee that the cooling-air of q.s is through cabinet on the other hand.The target that can become trasher for the larger external grid improving air stream on this cabinet, therefore the outside looks of cabinet need inconspicuous as much as possible.
In order to solve the subject matter of cooling, a solution increases the volume entering the air stream of cabinet.But, increase the speed entering the air stream of cabinet and can cause even more air bells laid particulate matter, thus reduce the life-span of any inlet filter.Although be effective with regard to short-term, this solution inevitably causes needs to change filter more continually.
Summary of the invention
Therefore the object of the invention is to solve one or more the problems referred to above.
According to a first aspect of the invention, a kind of equipment cabinets with air cooling system is provided, comprises:
Air intake, extends through the outer wall of described cabinet;

Described air intake filter preferably includes one or more panel, and described panel has the seta array extended from one or both sides.The type of this panel can be such as type disclosed in WO 2009/090405, comprises plug-in unit, this plug-in unit is applied with one deck filtering material.
By described first and second side panels lower edge between gap the air intake entering cabinet is provided.In this form, air intake is manufactured into least noticeable, and even under normal observation, also cannot see this entrance.Therefore the entrance of this form is conducive to reducing the risk causing damage by deliberately destroying.
Equipment cabinets can comprise the pipeline limiting inlet air flow path, and described pipeline is between the outlet side of described air intake filter and the bottom of the described internal capacity of described cabinet.Because filter extends through the outer wall of cabinet, therefore it is conducive to guiding air to wander about as a refugee the backward bottom down to cabinet of opened filter, thus the cooling effect of the equipment held in cabinet is maximized because the heat produced by equipment the warm air that heats trend towards rising and order about cold air through internal capacity.
Equipment cabinets can comprise the relative outer wall extending through described cabinet first and second described in air intake and described air intake filter.This is conducive to the cross-sectional area propagating through filter, makes the additional space shared by filter minimize simultaneously.
When using two air intake filters on relative outer wall, pipeline can form air flow path between each outlet side of air intake filter and the bottom of the internal capacity of cabinet, to guarantee that cooling-air arrives the bottom of the internal capacity of cabinet, to improve cooling effectiveness.
In order to improve cooling effectiveness further, especially when attracting a fan fails in air passes through inlet filter, pipeline can be isolated thing and be divided into two parts, air flow from described first and second air intake filters is become Part I and Part II by described spacer, this Part I extends between the described outlet side and the bottom of described internal capacity of described first filter, and this Part II extends between the described outlet side and the bottom of described internal capacity of described second filter.If a fan fails, spacer can guarantee that air is still attracted the bottom of inwardly volume, instead of flows out cabinet by another filter, can this thing happens when not using this spacer.
The pipeline extended between the outlet and the bottom of internal capacity of each filter advantageously can extend through the cabinet outer wall between the first and second filters, what make occupied by pipeline thus is space-minimized, and the available space for equipment in cabinet is maximized.
