Description
Technical field
The present invention relates to communication field, particularly a kind of dustproof case and router chassis thereof.
Background technology
At present, in order to prevent circuit board laying dust in router chassis and corrosion, the dustproof design of cabinet installs a fixing Air Filter, for tackling dust in the air inlet of cabinet.
The similar door and window structure of existing Air Filter, after after a while, dust is attached on wire side more and more, and after Air Filter blocking, change not in time or remove laying dust, air is difficult to circulation and enters cabinet, causes temperature in chassis too high, can cause online accident.Generally take manually to change Air Filter.Also have by relay, control to pat Air Filter, carry out dedusting.Drive Air Filter to carry out closed loop moving by motor, dedusting brush is positioned at below, and Air Filter, through out-of-date, gets final product dedusting.
Realizing in process of the present invention, inventor finds that prior art at least exists following problem: the maintenance cost that Air Filter is changed in periodic cleaning is higher.By relay, control the apparatus structure more complicated of patting Air Filter dedusting, take up room large, dust removing effects is poor.The two-layer Air Filter that the device air outlet driving Air Filter to carry out dedusting by motor is installed, radiating effect is bad, and uses brush dust removing effects poor, and the time, long dust was still piled up seriously.
Summary of the invention
The object of the embodiment of the present invention is the defect for above-mentioned prior art, provides a kind of cost low, the dustproof case of good dedusting effect.
The technical scheme that the present invention takes to achieve these goals is: a kind of dustproof case, comprise casing, be provided with circuit board in described casing, described casing one end is provided with opening, and the other end is provided with ventilation hole, induced draught fan and fan blowing is provided with in described opening, form air channel between described opening and described ventilation hole, the device on described circuit board is positioned at described air channel, wherein, when described induced draught fan is opened, described fan blowing is closed; When described fan blowing is opened, described induced draught fan is closed.
Another technical scheme that the embodiment of the present invention provides is: dustproof case is router chassis.
The beneficial effect that the technical scheme that the embodiment of the present invention provides is brought is: use casing structure of the present invention, when using induced draught fan heat radiation, because the device on circuit board stops wind direction, dust can be deposited near the pin of device, when needing the dust removing pin accumulation, stop induced draught fan, open fan blowing, then dry outward from ventilation hole, blow away dust near pin.By air draught and blowing the recycling of two kinds of radiating modes, can greatly reduce dust accumulation on circuit boards, good dedusting effect, prevents circuit board corrosion, reduce market return rate, and without the need to frequently changing Air Filter, use cost is low.
Accompanying drawing explanation
Fig. 1 is a kind of dustproof case structural representation provided in the embodiment of the present invention;
Fig. 2 is the another kind of dustproof case structural representation provided in the embodiment of the present invention.
In figure:
1 casing, 2 circuit boards, 3 openings, 4 induced draught fans, 5 fan blowings, 6 ventilation holes.
Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
See Fig. 1, a kind of dustproof case, comprises casing 1, is provided with circuit board 2 in casing 1, casing 1 one end is provided with opening 3, the other end is provided with ventilation hole 6, is provided with induced draught fan 4 and fan blowing 5, forms air channel between opening 3 and ventilation hole 6 in opening 3, device on circuit board 2 is positioned at described air channel, wherein, when induced draught fan 4 is opened, fan blowing 5 is closed; When fan blowing 5 is opened, induced draught fan 4 is closed.
The present invention does not use Air Filter, carries out dust removal process by the wind direction controlled in cabinet to circuit board surface.Case radiation mode is controlled, can realize air draught heat radiation and blowing heat radiation by switch induced draught fan and fan blowing.When long-time use induced draught fan heat radiation, because the device on circuit board stops wind direction, dust can be deposited near the pin of device, thus dust can near the accumulation of ventilation hole side on the pin of device, when needing the dust removing these accumulation, stop induced draught fan rotating, fan blowing is started working, then dry outward from ventilation hole, blow away dust near pin.When after dedusting end-of-job, recover normal mode of operation, close fan blowing, open induced draught fan.By recycling of these two kinds of radiating modes, can greatly reduce dust accumulation on circuit boards, good dedusting effect, prevents circuit board corrosion, reduces market return rate.
See Fig. 1, for ease of obtaining better dust removing effects, the wind direction of induced draught fan 4 and fan blowing 5 and the plane parallel of circuit board 2 mask placement device.
Be conducive to like this forming wind direction circulation, when induced draught fan runs, dust is scavenged into casing from opening, and when fan blowing runs, dust major part is scavenged into casing from ventilation hole.
See Fig. 1, induced draught fan 4 and fan blowing 5 can be placed side by side before and after opening 3, namely when opening 3 is provided with induced draught fan 4, induced draught fan 4 rear end is provided with fan blowing 5, also can select, when opening 3 is provided with fan blowing 5, fan blowing 5 rear end is provided with induced draught fan 4.Wherein, induced draught fan 4 can be the series connection of multiple induced draught fan, and fan blowing 5 can be the series connection of multiple fan blowing.
Select front and back side-by-side configuration, each fan work area is comparatively large, and heat radiation dust removing effects is relatively good.
See Fig. 2, induced draught fan 4 and fan blowing 5 can in opening 3 placements side by side up and down, and select to arrange induced draught fan 4 and fan blowing 5 with time-division upper and lower side on opening 3, namely opening 3 upper end is provided with induced draught fan 4, and induced draught fan 4 lower end is provided with fan blowing 5.Also can be provided with fan blowing 5 in opening 3 upper end, fan blowing 5 lower end is provided with induced draught fan 4.
See Fig. 1 and Fig. 2, in order to reach better dust removing effects, ventilation hole 6 is arranged on casing 1 side corresponding with opening 3, namely induced draught fan 4 and fan blowing 5 are set in casing 1 side, opposite side arranges ventilation hole 6, ventilation hole 6 can be multiple, arrange between the side of induced draught fan 4 and fan blowing 5 and the opposite side that ventilation hole 6 is set and form air channel, can by induced draught fan 4 and the wind direction of fan blowing 5 and the plane parallel of circuit board 2 mask placement device, device on circuit board 2 is positioned at air channel, work is carried out when induced draught fan 4 is different with fan blowing 5, by air draught and blowing the recycling of two kinds of radiating modes, can remove being deposited on device pin dust stratification, greatly reduce dust accumulation on circuit boards.See Fig. 2, ventilation hole 6 can certainly be set in the upside of casing 1.
When fan blowing runs, face formation air channel on circuit boards, dust is discharged outside casing by the ventilation hole of air channel through side.
Dustproof case of the present invention is particularly useful for router chassis, can reduce dust accretions in casing, reduces circuit board corrosion, reduces market return rate.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
