Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Present embodiment is a kind of implementation on optical transport platform, and optical transport platform is the backbone equipment in the television network broadcast system, is responsible for the sending and receiving of laser signal, is typical modular apparatus.Most of optical transport platform can be installed tens modules, and each module class is like the books shape, because density is high, module is difficult for heat radiation, and good cooling system is the key of optical platform steady operation.
Such as Fig. 1, shown in 2, the utility model comprises airduct 1, airduct 1 is that a cross section is the tubular structure of opening rectangle, and airduct 1 inboard opening part is installed printed circuit board 6, and printed circuit board 6 surrounds into closed tube with airduct 1, airduct 1 outside has one and discharges the air port, and the bottom has row's air inlet.The air outlet in airduct 1 outside is equipped with a plurality of fans 5, fan 5 is electrically connected with described printed circuit board 6, airduct 1 bottom has a plurality of air inlets, each air inlet is provided with a choke plate 2, choke plate 2 rotates is fixed on airduct 1 bottom, when choke plate 2 is closed, with the air inlet sealing of described airduct 1 bottom correspondence, when choke plate 2 was opened, described airduct 1 bottom was communicated with exhaust vent 8 on the need radiating module 7.Airduct 1 becomes the air channel that a multimode shares thus.Can realize the opening and closing of air inlet by the rotation of choke plate 2.
Described choke plate 2 is fixed on the mount pad 9 in the airduct 1 by rotating shaft 4, also is provided with locating part 3 on the mount pad 9, and described locating part 3 is positioned at choke plate 2 tops, stops that choke plate 2 rotates up to fixed angle, as shown in Figure 2.Choke plate 2 both can rotarily open the air channel smoothly like this, can prevent again its excessively electronic circuit of unlatching collision printed circuit board 6.
As shown in Figure 3, described choke plate 2 comprises a shield 2-1 and a baffle plate 2-2 who becomes fixed angle with described shield 2-1 who covers airduct 1 bottom air inlet mouth; When described shield 2-1 covered airduct 1 bottom air inlet mouth, baffle plate 2-2 stretched out airduct 1, and when the insertion of airduct 1 below needed radiating module 7, baffle plate 2-2 was headed into airduct 1 inside, and shield 2-1 upwards lifts, and unclamps described air inlet.Shield 2-1 and baffle plate 2-2 have flanging 2-3 away from rotating shaft 4 one ends, consist of a kind of counter weight construction that uses metal crimping to process, and can make choke plate 2 utilize the gravity self-resetting, close the air channel.
Fan 5 is installed in the air inlet in airduct 1 outside, will make the airduct 1 inner negative pressure that forms behind the fan work.Need radiating module 7 rear upper lateral parts to have exhaust vent 8, as shown in Figure 4, independent fan is not installed.After needing radiating module 7 correctly to enter the position, the exhaust vent of rear side and the air inlet of airduct just in time align, and air-flow will enter module from the module front side, leave module from rear side and enter airduct, discharge machine frame at last under fan 5 drives and finish heat sinking function.
Described fan 5 is connected with printed circuit board 6 by the lead-in wire with plug, can plug the lead-in wire of fan 5, replacing fan 5 in the situation that main frame does not cut off the power supply by airduct 1 air outlet.
Such as Fig. 5,6 are depicted as the utility model is installed on state in the rack, and airduct 1 is fixed on the rack rear, to the slot that provides a registration to use in the rack.Need radiating module 7 to insert in turn rack.Below introduce in detail action principle of the present utility model.
1. choke plate 2 is by a simple rotating shaft 4, i.e. the iron wire that unification runs through a plurality of mount pads 9 is fixed on airduct 1 inboard, can be rotated action around the rotating shaft iron wire.Locating part 3 also is the unified iron wire that runs through airduct 1 interior a plurality of mount pads 9.The effect of spacing iron wire is the anglec of rotation of restriction choke plate 2.
2. under the initial condition, such as Fig. 5, choke plate 2 is affected by self gravitation, is covered on the rectangle air inlet of airduct 1 and has covered air inlet, the closed condition of Here it is choke plate 2.During 5 work of airduct 1 rear side fan, the negative pressure of airduct 1 inside was lost efficacy, reduce rate of heat dissipation.For guaranteeing that choke plate 2 can not picked up by the negative pressure in the airduct, carried out bending at afterbody and the rotating shaft position of choke plate 2, play the counterweight effect.
3. when whole air inlets were closed, the negative pressure in the airduct 1 became obviously, and choke plate 2 can be because " pressure release " be carried out in obviously and slightly opening of negative pressure appearance." pressure release " phenomenon helps to reduce fan load, has protected the normal operation of fan.
4. after needing radiating module 7 to enter the position, such as Fig. 6, need radiating module 7 heads will clash into the baffle plate 2-2 of choke plate 2, cause choke plate 2 to rotate and be opening.
5. the airduct 1 framework outside is provided with a plurality of fans 5, each fan 5(common shaft flow fan) be fixed in airduct 1 outside by 4 screw axials.For air-flow between fan 5 and the airduct 1 is unimpeded, airduct 1 has been opened a plurality of big holes as air outlet.By big hole, the lead-in wire of fan 5 can directly be installed to the PCB 6 on its opposite.Big hole had both been realized ventilation, and the loading and unloading that realized fan 5 lead-in wires are arranged.In loading and unloading fan 5 processes, device systems need not outage, and the fan 5 that newly changes judges whether normal operation after plugging PCB by connecting line, if working properly can going again is mounted to the airduct 1 framework outside.
