The radiating effect of this cabinet.
In the present embodiment, the quantity of described fresh air inlet is 2, and two fresh air inlet symmetry intervals are formed on sidewall, heat radiation
The quantity of fan is 2, further increases the radiating effect of this cabinet.
The operation principle of the desktop communication devices cabinet of this oriented heat dissipating substantially can be such that
By the fan being installed in case side wall, cool exterior air is imported in cabinet by the fan at sidewall fresh air inlet
Portion, introduces enough air, and stop and the first exhaust vent, the second exhaust vent by case side wall guide air through whole machine
Case, produces windstream, at the upper radiator of installing of high thermal element (or all of heating element) to obtain enough radiating surfaces
Long-pending, the heat produced during cabinet inside height thermal element (or all of heating element) work is entered with windstream by radiator
Row heat exchange, windstream direction and flow velocity are controlled by air inlet and the first air outlet and the position of the second air outlet and size
System so that spreader surface obtains enough gas and carries out heat exchange, when heating element is at gas flow blind angle,
Forming gas flow channel by the second exhaust vent of enclosure top and carry out auxiliary heat dissipation, the element heating solving position, dead angle is asked
Topic.
In conjunction with Fig. 1 and Fig. 2, a kind of structure of the desktop communication devices cabinet of this oriented heat dissipating is explained further as follows:
Heating element on circuit board is respectively mounted Aluminium Radiator 31,32,33, unit's device according to heat condition during work
In the air that the heat produced during part work is dispersed in casing by radiator 31,32,33, the air outside cabinet pass through into
Under the effect of air holes 11 and fan 12, it flow on radiator 31,32,33 along cabinet length direction, heat is taken away, by
One air outlet 15 is discharged into outside cabinet, plays the effect reducing cabinet inside temperature, prevents cabinet inside components and parts due to ring
Border temperature too high causing damages.
The position of the heater element (it is high thermal element) on the position of the first exhaust vent 15 and the circuit board 21 of cabinet inside
Put corresponding setting, for cabinet inside without the circuit board 22 of heater element, corresponding at the cabinet side board of the first exhaust vent homonymy
Do not output air holes on position, the invalid of cabinet inside air-flow can be avoided to scatter and disappear, guide air-flow to go out to the first exhaust vent and second
Air holes flow, air first exhaust vent near is effectively ensured enough flow velocitys and air pressure so that be in the first exhaust vent and
Radiator 32 and 33 between fresh air inlet is in optimum Working.
For being in the radiator 31 within cabinet inside dead space, because it is in air inlet 11 and radiator fan 12
Far-end, present position cannot obtain enough radiating conditions, on cabinet top cover by the first air outlet 15 owing to structure limits
Opening the second exhaust vent 16, the position of the second exhaust vent 16 is corresponding with radiator 31, guides cabinet internal gas flow to pass through radiator
31 and upwards discharge cabinet from the second air outlet 16.
Extraneous air passes through air inlet 11 along cabinet length direction successively laterally across each circuit board of whole cabinet inside, electricity
Components and parts installation site on road plate 23 is along cabinet length direction, identical with cabinet inside airflow direction, opening of Aluminium Radiator
Groove direction is also identical with airflow direction so that cooling air-flow is completely covered whole circuit board.
Above-mentioned it is embodied as merely to the clearly explanation citing done of this utility model, and is not for this practicality newly
The restriction of the embodiment of type.For those of ordinary skill in the field, can make on the basis of the above description
The change of other multi-forms or variation.Technology of the present utility model can extend to other kinds of desktop communication easily
In equipment.Here without all of embodiment is given exhaustive.And that these belong to that this utility model spirit amplified out is aobvious
And within the change being clear to and variation are still in protection domain of the present utility model.
