Description
Technical field
The utility model relates to a kind of rack, particularly a kind of transmission heat radiation rack.
Background technology
In order to satisfy increasing transfer of data requirement, but telecom operators improve constantly the requirement of the big capacity business of transmission equipment bearer network, therefore, the volume of business of transmission system equipment is also in continuous increase, and in order to place more equipment in limited cabinet space, the density of equipment, power cause the caloric value of sub-frame to present the trend that straight line rises also in continuous increase, equipment needs bigger ventilation quantity, lower ambient temperature, satisfies the requirement of operate as normal.
Transmission sets up and is placed on fully in the dark rack of 300mm more, generally places 3～4 sub-framves in 2.2 meters high racks.Transmit sub-frame and in rack, mainly contain two kinds of draft types, air intake under first kind of employing, go up the draft type of air-out, in rack, place 3 sub-framves, as shown in Figure 1, cold air enters from sub-frame bottom, and the driving by sub-frame internal fan makes hot-air discharge from enclosure top, the air-flow smoothness, do not have obviously and reflux, heat radiation is better, as shown in Figure 2; Second kind is the transversal ventilation mode of ventilating about sub-frame adopts in rack, about many horizontal subracks that ventilate are placed on when working in the dark rack of 300mm, as shown in Figure 3, because rack left and right sides sidewall does not have perforate, and be subjected to rack to lean on wall and the also influence of cabinet placement, the rack rear side can not air-out, hot-air is back to air inlet by the gap between the sub-frame, form hot air reflow, heat is difficult to shed from rack, its wind direction as shown in Figure 4, at this moment, sub-frame inlet temperature can exceed about 5～15 ℃ of ambient temperature, and fan will full-speed operation, brings energy consumption to increase thus, the problem that noise increases, the equipment long-term work also can cause fan to damage in hot environment, the adverse effect that reduce equipment life.
Past is because data business volume is low, the sub-frame power consumption of ventilating about being placed in the rack is all little, even backflow is arranged, the phenomenon that the temperature superelevation also seldom occurs, and the influence that increased by traffic carrying capacity, the height of horizontal subrack, caloric value also constantly increase, and cause a large amount of hot air reflow to sub-frame air inlet, whole sub-frame temperature superelevation, promptly use more powerful fan to increase ventilation quantity, heat also is difficult to shed in rack.In addition, telecom operators are in order to cut down the consumption of energy, to control cost, building environment temperature by air-conditioning control also has trend of rising, the heat-sinking capability of ventilation transmission equipment was had higher requirement about this gave, therefore, be badly in need of the phenomenon that a kind of new rack level heat radiation solution is avoided horizontal subrack temperature superelevation in rack.
Existing transmission cabinets can not more and more can not satisfy the growth requirement of data service well to the left and right sides ventilation equipment radiating and cooling in the rack.
