Embodiment
The present invention is elaborated below in conjunction with accompanying drawing.
It is present system equipment composition and air channel schematic diagram, including machine case body 1, backboard 2, plug-in unit such as Fig. 1 and Fig. 2
Plate 3, the first wind deflector 4a, the second wind deflector 4b, air channel 5, air ejector fan 6, air inlet 15 and air outlet 16, backboard 2 and plug-in unit
Plate 3 is arranged in machine case body 1, and front portion is in one end using at case air inlet, and cabinet front lower ends are provided with air inlet 15, air inlet
15 rear ends are provided with the first wind deflector 4a, and cabinet rear upper end is provided with air outlet 16, and the rear end of air outlet 16 is provided with the second wind deflector 4b,
Air ejector fan 6 is additionally provided with air outlet 16, electronic cabinet uses the radiating mode of anterior air intake rear portion air-out, and cabinet inside is provided with
Backboard 2, backboard 2 mainly provides a kind of bus communication function, different boards can be made to be interconnected by backboard, due to machine
The operating of case aft fan cause cabinet inside formation negative pressure, cabinet in addition to fresh air inlet is left in front portion remaining be closure designs,
Cold air is merely able to the air inlet before cabinet and enters cabinet inside.Because the fan used is aerofoil fan, so shape
Into air channel be parallel air paths, the stops of cabinet inside parts and bending air channel form windage, in order to improve cabinet inside
Cooling effect, wind deflector 4 is added up and down inside electronic cabinet so that cabinet inside forms taper air channel 5, taper wind
Road 5 can ensure that cabinet fore-and-aft direction air enters or the blast of exclusion cabinet inside is roughly the same, improve the uniform of case radiation
Property.
Such as Fig. 3 and Fig. 4, including deep bead 7 and radiator 8, deep bead 7 is arranged on the lower end of radiator 8, is not increasing gear
Before aerofoil 7, the cold air of bottom is largely directly excluded along the less space without device of windage, causes short-circuit of air,
Radiating effect is not reached.Increase after deep bead 7, the cold air that bottom enters can only be along the radiator or other yuan on card
Device direction is flowed through, and device heat is discharged by fan by convection current, radiating effect is reached.
Such as Fig. 5 and Fig. 6, including pressing plate 9, spring assembly 10, sliding-tongue 11, slideway 12, collision bead 13 and collision bead locking apparatus 14,
Pressing plate 9 is fixed on machine case body 1, and collision bead locking apparatus 14 is located at the contact surface of sliding-tongue 11 and pressing plate 9, and pressing plate 9 is with keeping out the wind
Plate 7 blocks fixation by ratchet, and the bottom of deep bead 7 is provided with spring assembly 10, and the other end of spring assembly 10 is fixed on cabinet sheet
On body 1, when deep bead is changed, deep bead 7 only need to be pressed downwards, the ratchet on deep bead is departed from ratchet on pressing plate 9, sliding-tongue
11 smoothly pull out along slideway 12, and the collision bead 13 and collision bead locking apparatus 14 on slideway 12 ensure that suitable when deep bead is pulled out
It is sliding, prevent sliding-tongue 11 from blocking.
Air-exhaust type radiating electronic cabinet is forced the invention provides one kind, the method and approach of the technical scheme is implemented
A lot, described above is only the preferred embodiment of the present invention, it is noted that come for those skilled in the art
Say, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should be regarded as
Protection scope of the present invention.Each part being not known in the present embodiment can use prior art to be realized.
