Abstract
This invention is used as protective structure in outdoor cabinet / box of duct. Its structure is: the inside shutter is welded to doors or wall of the cabinet; the interceptor is installed hermetically in the door or wall after spraying; wind road store is installed hermetically in the door or wall; dust prevention network is installed under the wind road warehouse. When the cabinet forms negative pressure, the flow will be from outside cabinet ministry into interceptor and then from the dust prevention network at the bottom of the road wind store into cabinet through wind road. The advantages are as following: because the air inlet position's increase and the wind direction's changing, the possibility of the masons and large dust particles can be eliminated into the cabinet or blockage of dust network, and the amount of the fine dust particles into cabinet can be greatly reduced, the dust prevention effect can be greatly improved. Because of the addition of inside shutter and interceptor, the flow spray to the inside of the outer shutter will be reflected and pool to interceptor and then flow out of the cabinet, and will not flow into the cabinet. This fully meet IP55 level of GB4208 standard protection required.
Description
Technical field
What the present invention relates to is a kind of novel air duct safeguard structure that is used for outdoor cabinet/case, belongs to outdoor cabinet/case manufacturing technology field
Background technology
It is through type mostly that existing outdoor cabinet/case adopts the air channel safeguard structure of draft type heat radiation, and its weak point is: the air inlet position is low, and is overhead very near, is very easy to into ash when fine; The muddy water that rainwater or ground splash during the rainy day also is easy to enter.In addition, dust or muddy water can be blocked on the Air Filter, and it is not smooth to cause outdoor cabinet/case to ventilate, and influences the equipment operate as normal.The GB4208 standard code requirement of IP degree of protection, usually active equipment is had relatively high expectations to residing operational environment, requires to reach the IP55 grade standard.Obviously the direct through type air flue safeguard structure can not meet the demands.
Summary of the invention
The objective of the invention is to the defective at above-mentioned existence, propose a kind of novel air duct safeguard structure that is used for outdoor crate/cabinet, it can effectively overcome above-mentioned existing in prior technology outdoor cabinet/case and intake, advances defectives such as ash easily.It is based on following operation principle: two containers that connect mutually, the end that pressure is high when arbitrary end has pressure reduction will flow to the low end of pressure.
Technical solution of the present invention: its structure is that interior shutter is welded on cabinet door or the sidewall; Damming bucket sealing is installed on the rack/chamber door or sidewall after the spraying; The sealing of storehouse, air channel is installed on cabinet door/case or the sidewall; The Air Filter assembly is installed in the lower end in storehouse, air channel.
Advantage of the present invention: because the raising of air inlet position and the change of airflow direction; stopped the possibility that muddy water and bulky grain dust enter rack or stop up Air Filter; simultaneously also significantly reduced the amount that fine particle shape dust enters rack, dustproof effect is greatly improved.Owing to increased interior shutter and the bucket that dams, the current that are injected in outer shutter inboard flow out rack after the reflection of interior shutter is pooled to the bucket that dams, can not flow into rack.Reach the requirement of shelter of IP55 level in the GB4208 standard fully.
Description of drawings
Accompanying drawing 1 is user mode figure of the present invention.
Among the figure 1 is the cabinet door (or sidewall), the 2nd that has shutter, storehouse, air channel, the 3rd, interior shutter, the 4th, the bucket, the 5th that dams, wind direction, the 6th, outer shutter (on door or the wall), the 7th, air channel, the 8th, the rack outside, the 9th, rack inboard.
Embodiment
The contrast accompanying drawing, its structure is that interior shutter 3 is welded on cabinet door or the sidewall 1; Bucket 4 sealings of damming are installed on the rack/chamber door or sidewall after the spraying; 2 sealings of storehouse, air channel are installed on cabinet door/case or the sidewall; The Air Filter assembly is installed in the lower end in storehouse, air channel 2.
Improve the position of rack/case shutter air inlet, in shutter plane of symmetry layout one and former shutter consistent size, inside and outside shutter is symmetrical arranged, the few interior shutter in lower end.The bucket 4 that dams that more inboard shutter 3 usefulness upper ends is opened wide is sealed, and storehouse, air channel 2 sealings that at last bottom had Air Filter are installed in cabinet door inboard 9.
The air channel is in the assembling on the rack and the course of work: interior shutter 3 is welded on cabinet door or the sidewall 1.Bucket 4 sealings of will damming are installed on the cabinet door or sidewall after the spraying.2 sealings of storehouse, air channel are installed on cabinet door or the sidewall 1.The Air Filter assembly is installed in 2 lower ends, storehouse, air channel.
Dustproof: under the effect of negative pressure, the air-flow in the rack outside enters the storehouse, air channel through the shutter and the bucket upper end of damming, and the Air Filter assembly through lower end, storehouse, air channel enters rack inside downwards along the storehouse, air channel.Because the position of having improved shutter, the bulky grain dust can not enter shutter and storehouse, air channel, and the granule dust drops on inside, storehouse, air channel in the process of tenesmus or be blocked in inside, storehouse, air channel by the Air Filter assembly.
Waterproof: when rainwater was directly beaten outside around the shutter, the part rainwater can be splashed into outer shutter inside, and this part rainwater is stopped to launch downwards by interior shutter and dropping on outside the bucket outflow rack that dams.
Claims (1)
