Abstract
The invention relates to a cabinet for communication equipment. The cabinet comprises a communication equipment containing cavity and an air exhaust airflow channel which is defined in the cabinet and extends along a second direction, wherein one or more communication equipment units are arranged in the communication equipment containing cavity along a first direction; and a communicating opening opposite to the one or more communication equipment units is formed on the air exhaust airflow channel of the cabinet and is used for connecting the airflow channel and an airflow outlet of the communication equipment containing cavity. Therefore, cooling airflow entering the communication equipment containing cavity from an open side surface air inlet airflow channel of the cabinet flows through and cools the one or more communication equipment units along the first direction, and then the cooling airflow is changed into heat carried airflow to enter the air exhaust airflow channel of the cabinet through the communicating opening and flow out of the cabinet from the air exhaust airflow channel along the second direction.
Description
Technical field
The present invention relates to a kind of rack that is used for communication equipment.
Background technology
The operator of telecommunication apparatus uses jumbo equipment in the past always, but its demand growth for compact size equipment now is very fast.The equipment of these compact sizes normally internal circuit board slot is designed to along continuous straight runs and is installed on the rack to the cold mode of crosswind with side, this be with preceding arrive after the difference of maximum of air-cooled traditional large capacity equipment.
If with side to the cold equipment of crosswind be installed to generally held standard simply preceding to after rack in cool off; This will cause air-flow confusion in the rack; Because hot and cold air mixes mutually, cause cooling effectiveness to reduce, this is disadvantageous for requiring the high equipment of reliability.
Have three kinds of types of cooling in the prior art: installation again behind directly installation, the vertical heat-dissipating space of increase, tilting are installed.The two kinds of defective appropriateness mitigation scheme that are based on first kind in back.
Shown in Figure 1A; It shows directly, and the communication equipment unit that the side offside is air-cooled is installed in the rack of standard; The disadvantage of this scheme is; Because the discharge air-flow of the heat of cooling blast and the expection of expectation mixes fully, this means the expectation cooling blast relatively hot always that flows into the equipment entrance place, even the interior air-conditioning of machine room is being supplied cold air always in the space around the rack.Discover that will reduce 50% the useful life of part parts (for example alminium electrolytic condenser) if the every rising 10 of ambient temperature is spent then.
Shown in Figure 1B; Increase the vertical space between the air-cooled communication equipment unit of side offside; Thereby the surface of communication equipment unit more is exposed in the air-flow, and to improve radiating efficiency, the radiating efficiency of this mode is more better than the shown example of Figure 1A; But under the situation of compulsory convection current, still there is turbulence state.Even accidental be favourable, for example, natural heat dissipation. this mode is favourable to low-energy equipment only.
Other example shown in Fig. 1 C is installed the communication equipment unit obliquely with respect to the front of rack, thus at the cooling air of the new inflow of rack front, near the cooling of parts be favourable.The effect of this scheme also receives the restriction of following several aspects: the flow of cooling blast is increased but is not enough; This mounting means occupies more space; Certain customers do not accept this mounting means.
As shown in Figure 2, it shows the whole situation of rack of hot and cold air motion.Shown in Fig. 2 A, precedingly be installed on the rack to air-cooled communication equipment unit, back with traditional.Cooling blast enters into the inlet of communication equipment unit from the front side of rack, flow through the space between the communication equipment unit after, take the outlet that thermal current is discharged the communication equipment unit at last.In the space that the communication equipment unit is not installed of rack; Dividing plate is installed so that the front space and the back space of rack are isolated; Thereby; Make the air pressure difference between inlet air flow and the exit flow high as much as possible, thereby guide more cooling blast through the communication equipment unit, to reach good equipment cooling effect.The cooling charge air flow with take the thermal exhaust air-flow and isolate basically.
Shown in Fig. 2 B; It shows the communication equipment unit of new side to the sidewind cooling is installed on the conventional rack; Because the forced draft effect that the fan of equipment provides; Cooling blast after heat is taken away from the communication equipment unit, is taken the left side that thermal current is discharged to unit through the right side of the communication equipment unit of porch.Regrettably; After taking thermal current and leaving equipment, stopped by the side panel of rack; Thereby the thermal current of taking of discharging has to flow to the equiprobable place, preceding/back/top/end of communication equipment unit; The cooling blast of some in these air-flows and unit inlet mixes, and cooling blast no longer is a cooling blast and become cold and hot mixed airflow.By air-conditioning further before the cooling, some mixed airflows shuttling movement in rack produces harmful turbulent flow, is owing to turbulent flow causes shortcoming leaving rack: working under the environment of high-temperature very in the communication equipment unit, causes the high failure rate of equipment; The operator of communication equipment must dispose lower air-conditioner temperature, thereby causes the energy of consumption every day more; Maintenance cost increases: the air-conditioning deficiency of existing quantity satisfies high refrigeration capacity requirement; The humidity that turns back to the air-flow in the air-conditioning reduces, and this meaning need be carried out this extra evaporation process measure in air-conditioning, and this will waste more.
To the problems referred to above, as shown in Figure 1, prior art has proposed different solutions.
