Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, all belongs to the scope of protection of the invention.
As shown in Figure 2, for the structural representation of the communication single-board that the embodiment of the present invention provides, this communication single-board has printed circuit board (PCB) 21 and is positioned at the panel 22 for showing index signal on front side of printed circuit board (PCB) 21, and panel 22 is preferably vertical with printed circuit board (PCB) 21 to be arranged; The both sides of printed circuit board (PCB) 21 broad ways are provided with Handle Bar 23, and Handle Bar 23 is also preferably vertical with printed circuit board (PCB) 21 to be arranged, to protect printed circuit board (PCB) 21 and conveniently it to be extracted from rack.In order to dispel the heat to the power module being arranged on communication single-board rear, the space-closed surrounded with Handle Bar 23 by printed circuit board (PCB) 21, panel 22 is got up to be formed air channel 26 by the embodiment of the present invention, 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 present invention provides, is inserted in rack in use, and the power module be arranged in rack normally works to make it to communication single-board feed.Operationally, the cold wind of being come in by air inlet of air duct 24, through air channel 26, discharges from duct outlet 25 and blows to power module, and then the hot blast after heating is taken away to reach the object to power module heat radiation by the fan of power module.The air channel 26 of the communication single-board that the embodiment of the present invention provides is by the enclosure space that surrounds of existing structural member comprising 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, such communication single-board can the more subsystem of layout, improve level of integrated system, reduce costs.
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 panel 22.Such cold wind directly enters air channel 26 from the through hole panel 22, and transmission path is straight line, and windage is less, is beneficial to the transmission of cold wind to duct outlet 25.
Again referring to shown in Fig. 2 and Fig. 3, as the preferred version of above-described embodiment, through hole 24 is multiple, and is evenly distributed on region corresponding with air channel 26 on panel 22.Larger incoming air area can be realized like this under the prerequisite not reducing panel 22 rigidity, 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 shaping, also can be distinguished shaping by welding procedure and hole opening technology.Casting integratedly shapingly moulding process can be simplified.
As shown in Figure 3, as the preferred version of above-described embodiment, duct outlet 25 is connected with backboard 46 by air guide structure 42, backboard 46 offers ventilation hole 44, for air-flow is led to backboard 46 on need the operational module 45 that dispels the heat, air-flow to be led operational module 45 by the ventilation hole 44 on backboard 46 by the air-flow at duct outlet 25 place, dispels the heat to give operational module 45.
As shown in Figure 3, the embodiment of the present invention additionally 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 rear 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 be connected with duct outlet 25, for air-flow is led to operational module 45.
The communication equipment that the embodiment of the present invention provides, employ above-mentioned communication single-board 2, cold wind is after the air channel 26 of communication single-board 2, blow to operational module 45 from the ventilation hole 44 backboard 46, then the hot blast after heating is taken away to reach the object of dispelling the heat to operational module 45 by the fan of operational module 45.
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 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 a deviation position of the ventilation hole 44 like this on duct outlet 25 and backboard, this deviation can be eliminated 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.Such cold wind diminishes at pressure after trumpet-shaped air guide structure 42, and film-cooled heat increases, and can realize power module 45 Homogeneous cooling in a big way.
As shown in Figure 5, as the further improvement of above-described embodiment, operational module 45 is power module, and comprise power supply 451 and power supply fan 452, power supply fan 452 is positioned at the rear of power supply 451.Alternately carrying out on the same line of such cold wind and hot blast, windage is less, is more 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 shaping, also can be distinguished shaping by welding procedure and hole opening technology.Casting integratedly shapingly moulding process can be simplified.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change 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.
