Abstract
The utility model provides a radiation structure for a communication machine cabinet, which is used for overcoming the problem that the radiation effect of the prior art is not good and comprises a machine cabinet and a first radiation fan unit arranged on the communication machine cabinet. The utility model is characterized in that the direction of a rotary shaft of the first radiation fan unit is in the oblique state, corresponding to the top plane of the machine cabinet. When the communication machine cabinet of the utility model is used, as air is smoothly expelled out of the communication machine cabinet, the airflow noise can be notably reduced and the radiation effect can be improved.
Description
Technical field
The utility model relates to communication cabinet, particularly the radiator structure of communication cabinet.
Background technology
Along with the power of communication equipment constantly increases, its heat that is produced in running also constantly increases, and the ambient temperature that the increase of heat will cause electronic component or veneer to move rises, when temperature surpasses the temperature that electronic component or veneer allowed, will cause electronic component or veneer normally not to move, even damage electronic component or veneer, so it is just very necessary that communication equipment is dispelled the heat.
In the prior art, radiator fan is usually adopted in the heat radiation of communication equipment, drive air flowing between the rack interior circuit board to reach the forced air cooling effect of electronic system by fan unit.When concrete the application, following several concrete scheme is arranged:
Scheme one: as shown in Figure 1, axial fan unit places the plenum chamber on rack top, air stream enters in the rack from the air inlet of position, rack bottom plenum chamber, through groove bit space between each circuit board, the final air-flow slave cashier's office in a shop air outlet of portion's plenum chamber is discharged, thereby the heat of the components and parts of working on the circuit board is discharged outside the rack.Because the air intake and the air-out of aerofoil fan are same directions, when air flowed from the rack air-out, air flowed in the rapid break-in of upper plenum an angle of 90 degrees degree, caused windage to increase, and influenced the system radiating effect and produced big noise.
Scheme two: as shown in Figure 2, fan unit adopts centrifugal fan, and the air intake of centrifugal fan is vertical mutually with air-out, so just the end view of the air current flow form when fan unit is placed on the rack upper plenum presents the situation as Fig. 2.Centrifugal fan with air from axial suction, from radially discharging.Because the air intake of centrifugal fan is vertical mutually with air-out, feasible many row's centrifugal fans are difficult to carry out the parallel placement of coplane as aerofoil fan.So for the rack of the common degree of depth, single centrifugal fan is difficult to guarantee that the air flow field in circuit board layout zone, rack middle part is even, and radiating effect is exerted an influence.
The utility model content
The utility model provides the radiator structure of the good and low noise communication cabinet of a kind of radiating effect.
For achieving the above object, the utility model provides following technical scheme:
A kind of radiator structure of communication cabinet comprises: rack and be installed in the first radiator fan unit on the described communication cabinet, it is characterized in that: the rotor shaft direction of the described first radiator fan unit is inclined with respect to the top plan of rack.
The radiator structure of described communication cabinet is characterized in that, described radiator structure further comprises the second radiator fan unit.
The radiator structure of described communication cabinet is characterized in that, the rotor shaft direction of the described second radiator fan unit with respect to the top plan of rack in vertical state.
The radiator structure of described communication cabinet is characterized in that, described first, second radiator fan unit is respectively the fan group that is made of two radiator fans at least.
The radiator structure of described communication cabinet is characterized in that, described first, second radiator fan unit is arranged on the communication cabinet top, adopts the working forms of exhausting that the air in the communication cabinet is extracted out.
Communication cabinet of the present utility model, air stream have overcome the big and big shortcoming of noise of windage of prior art scheme one outside the more smooth-going discharge rack in top.Simultaneously, this fan unit also adapts to the bigger application of cabinet depth especially, has guaranteed by the air-flow of circuit board even.

Embodiment
Please refer to Fig. 3, fan unit schematic diagram of the present utility model, the scheme of fan unit is for to be divided into two groups with a plurality of aerofoil fans, the fan group 9 ' that one group of fan axis normal or near normal cabinet sidewalls are placed, another group for the fan axis with respect to the tilted-putted fan group 9 of cabinet sidewalls.The fan unit main body is by flap 13, the peripheral sheet metal support frame 12 of flap, the inclination that is installed on the flap 13 inclined-plane bcc ' b ' is placed fan group 9 and is installed in flap 13 vertical plane dgg ' d " vertical placement fan group 9 ' on (g ' point is on the corresponding medial surface of g point, Fig. 3 does not mark) forms.
Please refer to Fig. 4, the schematic diagram of the utility model scheme one.Fan unit is arranged on the top of rack 14, uses fan unit exhausting form work on the whole, and inclination placement fan group 9 deflates formation from rack air-flow is discharged from the air outlet corresponding with it 2 '; The vertical fan group 9 ' air-flow that forms that deflates from rack of placing is discharged from the air outlet corresponding with it 2.After two strands of air-flows come out from aerofoil fan, be to isolate mutually before discharging rack.Because air stream outside the more smooth-going discharge rack 14 in top, has overcome the big and big shortcoming of noise of windage of prior art.
As shown in Figure 5, be appreciated that to speeding ventilation velocity, further improve radiating effect, fan group 9 is placed in the inclination of fan unit can distinguish tandem fan group 19 and fan group 19 ' in the space according to cooling machine cabinet amount demand in position with vertical placement fan group 9 '.Certainly, if flap inclined plane bcc ' b ' has enough areas, can on the plate face, increase coplane or fan group in parallel.
In addition, please refer to Fig. 6, the utility model scheme two is in the application of rack bottom, and fan unit is arranged on the rack bottom, with the work of blowing form, can reach the purpose of this utility model equally, and this no longer is described in detail.
