Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work belongs to the scope of protection of the invention.
As shown in Figure 2, the structural representation of the communication single-board that provides for the embodiment of the invention, the panel 22 that be used for to show index signal that this communication single-board has printed circuit board (PCB) 21 and is positioned at printed circuit board (PCB) 21 front sides, panel 22 preferably with printed circuit board (PCB) 21 vertical settings; The both sides of printed circuit board (PCB) 21 broad wayss are provided with Handle Bar 23, and also preferred and printed circuit board (PCB) 21 vertical setting of Handle Bar 23 are extracted it with making things convenient for protection printed circuit board (PCB) 21 from rack.In order to give the power module that is arranged on communication single-board rear heat radiation, the embodiment of the invention will get up to form air channel 26 by the space-closed that printed circuit board (PCB) 21, panel 22 and Handle Bar 23 surround, and in the front side in this space air inlet of air duct 24 is set, rear side arranges duct outlet 25.
The communication single-board that the embodiment of the invention provides is inserted in the rack in use, be arranged on power module in the rack to the communication single-board feed so that its normal operation.When work, the cold wind by air inlet of air duct 24 is come in through air channel 26, blows to power module from duct outlet 25 discharges, and the hot blast after then the fan of power module will heat takes away to reach the purpose to the power module heat radiation.The air channel 26 of the communication single-board that the embodiment of the invention provides is the enclosure space that is surrounded by the existing structural member that comprises printed circuit board (PCB) 21, panel 22, Handle Bar 23, do not take the plate face of communication single-board and the space of floor height, communication single-board can the more subsystem of layout like this, improve level of integrated system, reduce cost.
As shown in Figures 2 and 3, as the further improvement of above-described embodiment, air inlet of air duct 24 is for being opened in the through hole on the panel 22.Cold wind directly enters air channel 26 from the through hole on the panel 22 like this, and transmission path is straight line, and windage is less, is beneficial to cold wind to the transmission of duct outlet 25.
Referring to Fig. 2 and shown in Figure 3, as the preferred version of above-described embodiment, through hole 24 is a plurality of again, and is evenly distributed on the panel 22 zone corresponding with air channel 26.Under the prerequisite that does not reduce panel 22 rigidity, can realize larger incoming air area like this, and be conducive to evenly entering of cold wind.
As the preferred version of above-described embodiment, described air channel, air inlet of air duct and duct outlet can by casting integrated moulding, also can be distinguished moulding by welding procedure and hole opening technology.Casting integrated moulding can be simplified moulding process.
As shown in Figure 3, preferred version as above-described embodiment, duct outlet 25 links to each other with backboard 46 by air guide structure 42, offer ventilation hole 44 on the backboard 46, be used for air-flow lead to backboard 46 on need the operational module 45 that dispels the heat, the air-flow at duct outlet 25 places by the ventilation hole 44 on the backboard 46 with the air-flow operational module 45 that leads, to give operational module 45 heat radiations.
As shown in Figure 3, the embodiment of the invention also provides a kind of communication equipment, comprise above-mentioned communication single-board 2 and be connected to the backboard 46 at communication single-board 2 rears and the operational module 45 of needs heat radiation, communication single-board 2 is connected with operational module 45 by backboard 46, backboard 46 is provided with the ventilation hole 44 that is connected with duct outlet 25, is used for air-flow is led to operational module 45.
The communication equipment that the embodiment of the invention provides, used above-mentioned communication single-board 2, cold wind is through after the air channel 26 of communication single-board 2, ventilation hole 44 from backboard 46 blows to operational module 45, and the hot blast after then the fan of operational module 45 will heat takes away to reach the purpose to operational module 45 heat radiations.
As shown in Figure 3, as the further improvement of above-described embodiment, be provided with air guide structure 42 between communication single-board 2 and the backboard 46, the air inlet 41 of air guide structure 42 connects duct outlet 25, and the air outlet 43 of air guide structure 42 connects the ventilation hole 44 of backboard 46.If when there is deviation the position of the ventilation hole 44 on duct outlet 25 and the backboard like this, can eliminate this deviation by air guide structure 42, cold wind is guided to operational module smoothly, to realize the cooling heat dissipation to operational module.
As shown in Figure 4 and Figure 5, as the further improvement of above-described embodiment, the cross-sectional area of the air outlet 43 of air guide structure 42 is greater than the cross-sectional area of the air inlet 41 of air guide structure 42.Cold wind is diminishing through pressure behind the trumpet-shaped air guide structure 42 like this, and film-cooled heat increases, and can realize power module 45 even cooling in a big way.
As shown in Figure 5, as the further improvement of above-described embodiment, operational module 45 is power module, comprises power supply 451 and power supply fan 452, and power supply fan 452 is positioned at the rear of power supply 451.So alternately carrying out at same straight line of cold wind and hot blast, windage is less, more is conducive to the cooling heat dissipation of power module.
As the preferred version of above-described embodiment, described air channel and described air guide structure can by casting integrated moulding, also can be distinguished moulding by welding procedure and hole opening technology.Casting integrated moulding can be simplified moulding process.
The above; be the specific embodiment of the present invention only, but protection scope of the present invention is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of described claim.
