Stating shutter has arrangement up and down and not higher than the opening of vent height, and the shutter is in opening's edge under the opening of bottom
It is flushed with the lower wall surface in the air duct.
The lower wall surface in the air duct is set diagonally downward from inside to outside.
Gauze is covered in the opening inner side of the shutter.
Filter cotton is equipped in the ventilation opening outside mask.
The invention also discloses a kind of outdoor cabinet using above-mentioned dustproof and waterproof structure, the technical solutions of the outdoor cabinet
It is：A kind of outdoor cabinet, including cabinet, until less than more than two ventilation openings are vertically equipped at intervals on the side side wall of cabinet,
It is covered with shutter respectively outside each ventilation opening, is enclosed between each ventilation opening and corresponding shutter equipped with air duct, the shutter has
It arranges up and down and not higher than the opening of corresponding vent height, the lower opening's edge of the shutter bottom opening and corresponding air duct
Lower wall surface flushes.
The lower wall surface in each air duct is set diagonally downward from inside to outside.
Gauze is also covered on the inside of the shutter.
Filter cotton is also covered on the outside of the ventilation opening.
The ventilation opening positioned at cabinet top is exhaust outlet, and the ventilation opening positioned at cabinet lower part is air inlet, in institute
It states and axial flow blower is additionally provided on the inside of air inlet.
The present invention is to move down the shutter being set to outside ventilation opening on outdoor cabinet side wall, opens the shutter lowest level
The lower opening's edge of mouth and the lower wall surface in air duct are flush, and are discharged, avoided in time so as to which the water condensed in air duct be made to pass through shutter
Water stops in air duct, simple in structure, not only effectively extends the service life of cabinet, but also ensures to be mounted in cabinet
Electrical equipment operates under good internal environment always so that the class of safety protection of outdoor cabinet is further carried
It is high.
Description of the drawings
Fig. 1 is the partial structural diagram of outdoor cabinet specific embodiment of the present invention；
Fig. 2 is the A portions enlarged drawing in Fig. 1.
Specific embodiment
As shown in Figure 1 and Figure 2, the outdoor cabinet is at least in one side side wall for the specific embodiment of the outdoor cabinet of the present invention
It is set on 100 by what bottom to top was vertically spaced there are three the ventilation device being used for for cooling machine cabinet, wherein, positioned at the logical of top
Wind apparatus is the air exhausting device 101 for the high temperature in cabinet to be discharged, and two ventilation devices of middle part and lower part are to cabinet
The air-intake device 102 of interior air feed, air-intake device 102 are respectively provided with the ventilation opening offered in cabinet sidewalls 100 with air exhausting device 101
And shutter outside corresponding ventilation opening is covered at, wherein, the ventilation opening in air-intake device 102 is air inlet, positioned at air draft
Ventilation opening in device 101 is exhaust outlet, be equipped in air exhausting device 101 and air-intake device 102 for prevent water vapour and
The impurity such as dust enter the dustproof and waterproof structure inside cabinet by first corresponding ventilation opening.
The present embodiment is by taking the dustproof and waterproof structure in air-intake device 102 as an example, as shown in Fig. 2, in the present embodiment, the air inlet
Device 102 is the groove 1 that indent is dug in cabinet sidewalls 100, and air inlet is offered on the groove bottom wall top in groove 1
Mouth 2, the shutter 3 concordant with cabinet sidewalls 100 is covered in the notch of groove 1,3 lower part of shutter offers what is arranged up and down
Opening, there are gap between air inlet 2 and shutter 3, the cell wall of 1 surrounding of groove surrounds the wind of connection shutter 3 and air inlet 2
Road 4, each opening of shutter 3 are not higher than air inlet 2, wherein, under the lower opening's edge of the opening of 3 bottom of shutter and air duct 4
Wall surface 5 flushes, so as to which the water condensed in air duct 4 is discharged in time.Gauze is also covered in the opening inner side of shutter 5
（Not depending on going out in figure）, filter cotton 6 is equipped in the outside mask of air inlet 2.For the ventilation of reinforcement interior of equipment cabinet, radiating efficiency is improved,
It is further fixed on axial flow blower 7 on the inside of air inlet.
Air exhausting device 101 and the structure of air-intake device 102 are essentially identical, between the two differ only in air exhausting device
In 101 exhaust outlet axial flow blower is not installed.
When cabinet works outdoors, the extraneous air containing impurity such as water vapour, dust enters air duct by shutter 3
In 4, the larger dust of particle stops that the smaller dust of particle and water vapour are by air inlet 2 by the gauze that 3 inside of shutter is set
The filter cotton 6 of outer setting stops, so as to which dry, clean air only be allowed to enter in cabinet, after water vapour condenses in air duct 4
The droplet of formation, which flows to be open by 3 bottom of shutter on the lower wall surface 5 in air duct 4, to flow out, and water is avoided to be retained in air duct 4.
After the temperature in cabinet reaches certain limit, the axial flow blower 7 in air-intake device 102 is started to work, air from cabinet, under
The air-intake device 102 in portion, which enters in cabinet, drives the heat generated during electronic device works flowing to rise, finally by most upper
Exhaust outlet and shutter discharge cabinet in the exhaust apparatus 101 of side, form air circulation, reduce and made due to heat concentration of local
The damage of pairs of component, so as to extend the service life of outdoor cabinet.
