Abstract

The utility model discloses a dustproof computer case; a counter bore is formed at the lower part of the front panel of the case; the bore wall of the counter bore extends backwards and stretches into the case; the rear end of the counter bore is contracted; the aperture of the contracted part is smaller than that of the counter bore; a tubular filter element tube is mounted in the counter bore; an air inlet duct is arranged in the circumferential direction on the wall of the tubular filter element tube; the front end of the tubular filter element tube is sealed; and an outward extending ear is arranged at the sealed end. The ear is matched with the counter bore part; and air inlets communicated with the counter bore are formed in the circumferential direction on the ear; the rear end of the filter element tube is in threaded connection with a step; a fan is mounted at the rear end of the filter element tube; and a filter screen is sleeved on the outer surface of the filter element tube. Compared with the prior case, the filtration system of the dustproof computer case has a larger filtration surface, and the air intake amount is increased; moreover, an independent air intake fan is added, thereby ensuring that a large amount of air can enter the case and the air intake amount of the case can not be influenced when the air is filtered.

Description

The Dust-proof computer cabinet

Technical field

The utility model relates to a kind of Dust-proof computer cabinet, specifically, is a kind of Dust-proof computer cabinet.

Background technology

At present, common air-cooled computer housing is the air admission hole in side, back and dead ahead by computer housing, and the formation of the fan on power supply cross-ventilation, dispels the heat for CPU, video card.Yet dust in air is accompanied by air and enters together in the cabinet, accumulates on the heating radiator of CPU, video card and north and south bridge, reduced the heat transfer effect of aluminium alloy heat radiator, directly influence the effect of wind-cooling heat dissipating, made each element job insecurity, shortened the serviceable life of parts; Even when air is moist, make the dust conduction form short circuit and burn electronic component; And when making in the slots such as internal memory, video card, can cause slot and accessory loose contact when dust accumulation.

In order to address the above problem, Chinese patent CN200420007472.1 discloses " a kind of computer housing ", the front panel of this cabinet is provided with dismountable air inlet panel, be densely covered with most fresh air inlets on the described air inlet panel, fresh air inlet communicates with cabinet inside by the passage on the front panel, between described air inlet panel and front panel dustproof filtering device is installed also.Adopt this filtration unit filtering dust in air to a certain extent, but, the surface area of the filter screen of this filtration unit is little, the density of filter opening is big on the filter screen, and filter effect is limited, and, because this cabinet adopts passive air intake, intake is little, will reduce the cold air inlet, influences radiating effect.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of Dust-proof computer cabinet, this computer housing good dustproof effect, and air inflow is big.

In order to address the above problem, the technical solution of the utility model is:

A kind of Dust-proof computer cabinet comprises front panel, is provided with counterbore in the bottom of described front panel, and the hole wall of this counterbore extends back, and stretches in the cabinet, closes up in the rear end of this counterbore, and the aperture of this mouth is less than the aperture of counterbore; The tubulose filter tube is housed in described counterbore, wall upper edge at this filter tube circumferentially is provided with air inlet duct, the front end sealing of this filter tube, be provided with outwardly directed ear at this blind end, this ear divides with the countersink region of described counterbore and cooperates, and being circumferentially with the air admission hole that communicates with described counterbore in this ear upper edge, the rear end of described filter tube is threaded with described step, in the rear end of this filter tube fan is housed; Outside surface at described filter tube is set with filter screen.

As preferred embodiment of the present utility model, be circumferentially with four camber air admission holes in described ear upper edge.Described air inlet duct is a rectangle, and the length direction of this air inlet duct is consistent with the axial direction of described filter tube.

Compared with prior art, the beneficial effects of the utility model are:

(1) filter area of the utility model filtering system is big, has increased air inflow; And, also increased independently supply fan, guarantee that a large amount of cold airs enters in the cabinet, make in filtered air, can not influence the air inflow of cabinet;

(2) cold air enters from the bottom in cabinet the place ahead, after carrying out heat interchange with hot-air, be discharged to the cabinet outside, formed the hot switching path of " from bottom to top " through the exhaust fan of power supply, the effect of heat radiation obviously improves, and lowers 3～5 degree than common computer cabinet inside temperature;

(3) filter tube is threaded with counterbore, and installation and removal are convenient; And filter screen set is contained in the outside surface of filter tube, after using a period of time, can easily filter screen be taken out, and is convenient to clean.

Fig. 2 is that A along Fig. 1 is to view;

Fig. 3 is the decomposing schematic representation of the utility model panel and filtration unit.

Embodiment

Further the utility model is illustrated below in conjunction with drawings and Examples.

As shown in Figures 1 to 3, the Dust-proof computer cabinet, front panel 3 by cabinet 1 and cabinet 1 front side is formed, on each side plate of cabinet 1 air intake opening is set no longer, only with counterbore 3a through hole is set relatively on the header board 8 of cabinet 1, the middle position, bottom of plate 3 is provided with counterbore 3a in front, and the hole wall of this counterbore 3a extends back, and stretch in the cabinet 1, by this counterbore 3a the inside of cabinet is in communication with the outside.Close up in the rear end of counterbore 3a, the aperture of this mouth 3b is less than the aperture of counterbore 3a, and be provided with screw thread at the inwall of mouth 3b; Tubulose filter tube 5 is housed in counterbore 3a, the front end sealing of this filter tube 5, and be provided with outwardly directed ear 5a at this blind end, this ear 5a divides with the countersink region of described counterbore 3a front end and cooperates, be circumferentially with four camber shape air admission hole 5b in described ear 5a upper edge, the rear end of described filter tube 5 is connected with the inner thread of described step, on the wall of this filter tube 5, be provided with rectangle air inlet duct 5c, the length direction of this air inlet duct 5c is consistent with the axial direction of described filter tube 5, in the rear end of this filter tube 5 fan 7 is housed; Outside surface at described filter tube 5 is set with filter screen 6.

Work as booting computer, fan 7 gets electric work, beginning is drawn into air to cabinet 1 inside, air enters in the computer housing through four camber air admission hole 5b, filter screen 6, four air inlet duct 5c, based on the hot-air principle lighter than cold air, the cabinet that do not stop from the cabinet lower curtate of fan makes the Hot air quilt cold air of generations such as CPU, video card be lifted to the top of cabinet to being drawn into clean cold air in addition, fan by computer power 4 is discharged to the cabinet outside, arrives the purpose of cooling like this.Because all computer powers 4 all are to outside air draft, exhaust air rate is all in 0.5～0.9 cubic meters per minute.The utility model filtrator mounted fan is 2000～3000 rev/mins of diameter 10CM rotating speeds, 1.1～0.9 cubes/minute of its airsheds after installing screen pack additional, because air inflow to have surpassed air capacity, therefore, can not reduce the air inflow of cabinet behind installation the utility model.
