Description

The air-cooled dust guard of the malleation of main frame

The utility model relates to the air-cooled dust guard of malleation of the anti-dust protecting device of the air-cooled microelectronic product of a kind of machinery, particularly a kind of main frame.

Main frame internal heat dissipating problem solves according to the exhaust ventilation principle in the market, its inner wind path flow process is to be positioned at the hot-air that axial fan in the host power supply box discharges cabinet inside, cause the air pressure in the cabinet to be lower than external pressure, make it in case, to form negative pressure state, the cold air of cabinet outside is under this suction function, from be distributed in cabinet everywhere air vent and the slit of component-assembled enter inside, give the cooling of the parts be in febrile state.Though can improve some radiating effects like this, because the air intake passage on the cabinet is dispersed in casing everywhere, the assembling slit of each parts junction also can become the inlet of cooling air, thereby dust in air also will be along with cooling air is gone into from accompanying everywhere.The dustproof requirement of microelectronic product is generally all very high, but the environment for use of general family expenses and commercial computer is difficult to reach the desired dustproof standard of computer manufacturer.The slot that falls to expiring dust can make the expansion card of newly plugging produce the fault of loose contact, so that walked detour in maintenance job; Particularly locate at floppy drive door, CD-ROM drive door etc., heap block dust to come off after, can be absorbed by cold wind and damage disc or read/write head, the fault that causes read-write difficulty or disc to scrap.Accumulate in the very easily moisture absorption and the influence heat radiation of dust on the circuit board in addition, but also can reduce the insulation degree between circuit and the element, the added burden when having increased the weight of some parts operations has been quickened the aging degree journey of element, has increased the rate of breakdown of complete machine.

The purpose of this utility model is the air-cooled dust guard of malleation of a kind of main frame of developing at above problem, and it has adopted positive draft dedusting wind path technology, and promptly the air pressure of cabinet inside is higher than its peripheral outer atmospheric pressure.This technology can prevent the pollution invasion and attack of dust to the main frame internal electronic component effectively under the prerequisite that guarantees the main frame radiating effect.

The utility model is achieved in that the air-cooled dust guard of the malleation of main frame comprises axial fan 1, wherein the cooling air air inlet 3 on the cyclone dust collector 2 is located on the surface of main frame casing, axial fan 1 is housed in cyclone dust collector 2, axial fan 1 and cyclone dust collector 2 are contained on the same axis, hot blast baffle assembly 7 is contained on the interior upper space position of main frame casing, there is exhaust of hot air mouth 8 the main frame casing both sides on hot blast baffle assembly 7 tops, on the main frame casing and and the position of host power supply box 5 correspondences exhaust of hot air mouth 6 is arranged.

The utility model can be achieved in that also hot blast baffle assembly 7 is made of the V-type plate sheet.

The utility model can also be achieved in that four cooling air air inlets 3 on the cyclone dust collector 2; Fly-ash separator handle 4 is arranged on the cyclone dust collector 2.

Good effect of the present utility model is:

1, this product usable range is wide, and it can not only be applied on the main frame, also is applicable in the air-cooled microelectronic product of other kind.

2, this product adopts positive draft heat radiation dedusting air path system, and promptly the air pressure of cabinet inside is higher than its external pressure on every side, under the prerequisite that guarantees the computer to dissipate heat effect, can prevent the invasion and attack of dust to computer-internal effectively.

3, this product structure is simple, air intake is concentrated, can effectively reduce after the use because of dust, moist and a series of problems of causing, it can improve the working environment state of microelectronic device, prolong its serviceable life, improved the degree of reliability of the safe operation of equipment, this is even more important for the electronic equipment that operates in important industry and key departments.

Description of drawings.

Fig. 1 is that the utility model is assemblied in the structural representation front view in the main frame.

Fig. 2 is the vertical view of the utility model Fig. 1.

Fig. 3 is the side view of the utility model Fig. 1.

The utility model is described in further detail below in conjunction with accompanying drawing.

Referring to Fig. 1,2,3, as shown in Figure 1.The air-cooled dust guard of the malleation of main frame mainly is by axial fan 1, cyclone dust collector 2 and hot blast baffle assembly 7 are formed, under the effect of axial fan 1, cold air outside the main frame is through cooling air air inlet 3, after cyclone dust collector 2 udst separations, after entering cabinet inside and carrying out heat interchange, drain into outside the case via each air vent and each assembling slit again, play the effect of each electronic devices and components in the cooling mainframe box with the electronic devices and components of heating.Four cooling air air inlets 3 are arranged on the cyclone dust collector 2, scribble viscous coating on the inwall of cyclone dust collector 2.The dust in air particle is done irregular circular motion and separated under the blade effect of axial fan 1, stick on the inwall of cyclone dust collector 2, and the air that enters in the computer host box is purified.The fly-ash separator handle is housed 4 on the cyclone dust collector 2, treats that the dust of cyclone dust collector 2 accumulates more for a long time, can pull out cyclone dust collector 2 easily by fly-ash separator handle 4 and clean, to guarantee the dust removing effects of cyclone dust collector 2.Hot blast baffle assembly 7 is made of the V-type plate sheet, each air port is up-small and down-big, hot-air in the computer host box flows from bottom to top, during through the air port, flow velocity is by accelerating slowly, and according to the principle that fluid mechanics flow velocity and pressure are inversely proportional to, bottom, air port pressure is greater than the air port upper pressure, be that hot-air can only be up, can not reflux.Accumulate in the hot-air on hot blast baffle assembly 7 tops, be discharged to the casing outside by exhaust of hot air mouth 8.On the main frame casing and and the exhaust of hot air mouth 6 established of the position of power pack 5 correspondences are downward-sloping air outlets, it is used to discharge the hot-air in the power pack 5.

Each several part establishment of component of the present utility model is simple, easy for installation.Referring to Fig. 1, for horizontal main frame, only need the fan in the host power supply box 5 is moved to the mainframe box bottom, and change air supply direction (by the outside blowing hot-air in inside, change is blown a cold wind over to inside by the outside, the direction of arrow is represented the direction of air flow among the figure), it is just passable to install hot blast baffle assembly 7 on the upper space position in the main frame casing additional, can also use for the vertical type machine main frame.
