Abstract
The utility model relates to a dust-proof computer case. An air filter is additionally arranged on an air inlet hole of a computer case which is originally provided with an air inlet, an air outlet and a fan, and a dust-block sheet is additionally arranged on the air outlet hole. The utility model can carry off heat which is emitted by computer hardwares, and can also prevent harmful matters in air such as dust, etc. from disturbing the normal running of computers. The utility model can be used for chassises and cabinets of hardware devices of large, medium and small-sized computers.
Description
The utility model relates to the dustproof casing of a kind of computing machine.
At present, the structure that has of known computer housing be by bring into, the engine housing of air outlet, fan constitute.Air filter is not established in housing air intake aperture, can't prevent that nuisance such as dust from entering casing, is easy to make computing machine to be subjected to nuisance infringements such as dust.The casing that has adopts totally-enclosed, the dustproof cooling structure of semiconductor refrigerating, cost height, power consumption are big, are difficult to promote.
The purpose of this utility model provides a kind of dustproof computer housing, and not only result of ventilating heat dissipation is good for it, and can prevent nuisance such as dust infringement computer hardware, and cost is lower again.
The purpose of this utility model is achieved in that and has into and out of the air port that air filter is equipped with in the air intake aperture on engine housing; The dust-break sheet is equipped with in the air-out aperture; Advancing or the air-out aperture is provided with fan.During computer operation, fan and dust-break sheet are opened, the housing outer air enters in the housing behind the nuisances such as air filter elimination dust of air inlet, discharge outside the casing through hardware, air-out aperture again, both the heat that computer hardware can be given out was taken away, and can prevent nuisance infringement computing machines such as dust again.During the computing machine off working state, air filter and dust-break sheet can stop nuisances such as dust to enter casing.
Owing to adopt such scheme, air filter and dust-break sheet outside the casing, can prevent nuisance harm computer security such as dust with nuisances such as dust in air retaining effectively.
Air filter can be selected filtering, absorption, absorption for use, and preferably is easy to unpick and wash, change the structure of filter material.For guaranteeing dustproof effect,, bonding or spray sealing strip, fibre fluff at the surface of contact of each parts joining place of housing and housing and hardware device joining place.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the horizontal dustproof casing side of a utility model computing machine negative pressure longitudinal profile organigram.
Fig. 2 is the horizontal dustproof casing side of a utility model computing machine malleation longitudinal profile organigram.
Among the figure (1). be computer housing body (2). be hardware device (3). the air filter (4) that is mounted in housing air intake aperture is that fan (5) is a canopy formula dust-break sheet
When computer operation, exhaust fan (4) work, dust-break sheet (5) is blown afloat and air draft outside casing (1), be negative pressure in the casing, the shell outer air enters casing, again through hardware device (2) behind nuisances such as the overanxious device of air (3) filtering dust, fan (4) is carrying the heat that hardware gives out and is discharging outside the casing.When computing machine cut out, the air filter (3) and the retaining that hangs down can prevent that at the dust-break sheet (5) of housing (1) air outlet dust etc. from entering casing.
In embodiment illustrated in fig. 2, modes such as the overanxious device of air (3) adopts and inserts, card seal on the air inlet that is installed in engine housing (1), and suction-type fan (4) is facing to the air intake (2) of engine housing (1), and the air outlet of engine housing (1) adopts the concave type structure.
When computer operation, fan (4) work, the air of nuisances such as dust that sucked device (3) filtering after filtration is malleation in the shell, clean air is discharged outside the casing through the air-out aperture of hardware device (2) and housing (1), and the heat that hardware gives out is taken away.Shut down computer, because the interior airless of casing (1) produces, dust in air also is difficult to enter in the casing by air intake aperture that filtration unit (3) is housed and casing (1) concave type air-out aperture.
Because fan (4) air draught work, casing (1) internal gas pressure is higher than the external world, nuisances such as dust can't be from the air-out aperture and other slit of chassis shell enter in the casing.Adopt this kind technical pattern, the joining place of housing each several part need not seal also can guarantee dustproof preferably effect.
When adopting present technique to make large and medium-sized computer cabinet, rack,, can establish several or the some groups of corresponding turnover wind apertures that are provided with air filter (3), fan (4), dust-break sheet (5) according to the structure and the heat radiation needs of hardware device.
Claims (4)
1. the dustproof casing of a computing machine, bring into, the computer housing body in air-out aperture advance or air outlet on fan, air filter, dust-break sheet are housed, it is characterized in that: on the air intake aperture of engine housing, air filter is installed.
2. the computing machine according to claim 1 casing that prevents dust, it is characterized in that: fan is directly installed on advancing of casing or the air-out aperture, casing advance or the air-out aperture facing to the fan of establishing in the casing.
3. according to claim 1 and the dustproof casing of 2 described computing machines, it is characterized in that: the dust-break sheet is established in the air-out aperture of engine housing.
4. according to claim 1 and the dustproof casing of 2 described computing machines, it is characterized in that: the dust-break sheet is not established in the air-out aperture of engine housing.
