Description
Technical field
The present invention relates to Box of electric machine technical field, particularly relate to a kind of for the electrostatic precipitation dust guard in cabinet.
Background technology
In Box of electric machine or rack technical field, the important index that guarantee electronic device normally runs is the temperature of whole cabinet inside, such as in machine room, in order to ensure the normal operation of electrical equipment, often adopting and installing air-conditioning temperature-reducing additional, or increasing the power of fan, after being corroded by dust, more easily produce high temperature at prior art electronic device and cause unnecessary loss, although installed screen pack on some cabinet, filter screen is meticulous easily to have got clogged, impact heat radiation; Filter screen does not excessively slightly reach dust-proof effect; Especially in the area that a few thing environment is poor, this phenomenon is even more serious, therefore needs a kind of technical scheme badly and solves the defect existed in Box of electric machine heat radiation and dedusting.
The dedusting technology of current main flow has sedimentation (industry is except bulky grain dust); cyclonic separation (is applied to industry the earliest; now some dust catcher with; require higher to wind pressure and wind speed; fan in cabinet does not reach the requirement of cyclonic separation); filter screen (such as extra large handkerchief filter screen, although can filter PM2.5, windage is large).Also the case be applied to by electrostatic precipitation in cabinet is had, as air purifier, but first the electrostatic precipitation be used at present in purification of air will produce high-pressure electrostatic by a series of booster circuit, defect is complex structure, take up room large, professional technique requires high, and needs additionally to provide electric power, is generally difficult to carry out repacking upgrading to existing cabinet.
Summary of the invention
The present invention aims to provide a kind of electrostatic precipitation dust guard, solves cabinet inside electronic device blocked by dust erosion, anti-dust filter mesh, the problem that radiating effect declines.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of cabinet electrostatic precipitation dust guard, comprise chassis body, chip cooling sheet, at cabinet air intake vent, place arranges metal screen, and metal screen is connected with conductive material with chip cooling sheet.
At cabinet inside, especially computer cabinet, at least has a high-frequency semiconductor chip (such as CPU) for calculating, and this chip caloric value is comparatively large, can be used for heat radiation by covering metal fin above.Due to the in harness electric capacity of cabinet inside, inductance, high frequency semiconductor chip, metal fin then can because of electrostatic charge on antenna effect band.With wire, fin is connected with metal screen, then metal screen also can brings electrostatic charge.Metal screen is arranged on cabinet air intake vent place, utilizes electrostatic absorption principle, filters out the dust entered in cabinet air, thus alleviates cabinet inside and each device dust stratification situation, ensures the smooth heat radiation of electronic device thus normally runs.
Use insulating materials to install between described metal screen and cabinet, avoid electric charge to be transmitted on cabinet.
The two ends of described conductive material are flexibly connected with fin and metal screen respectively, are conveniently disassembled from fin and metal screen by conductive material, also facilitate and directly carry out repacking upgrading to existing cabinet; Described flexible connection can use movable metal holder or buckle.
Described conductive material can be wire, conducting strip or contact tube etc.
Described conductive material preferred cross sectional area is the copper core cable of 4 square millimeters.
Described metal screen mesh can be various shape, as square, circular, polygon, random shape etc.
Described metal screen mesh size is 25 square millimeters to 1000 square millimeters, preferably 25 square millimeters, and it is comparatively large that mesh does, and can avoid being blocked by dust; And owing to adopting Electrostatic Absorption dust, can't be excessive and do not reach dust removing effects due to mesh.
Described metal screen thickness is 10 millimeters to 30 millimeters, preferably 25 millimeters, and suitably thickening metal screen can increase dust containing capacity.
The lower wind direction of described metal screen can also arrange at least 1 layer of additional metal filter screen, and to strengthen dust suction filter dirt effect, each layer metal screen connects successively, guarantees to receive to transmit by conductive material the electrostatic charge come.The mesh size of described additional metal filter screen is for being less than or equal to 10 square millimeters; The mesh of additional metal filter screen is less than the metal screen mesh be directly connected with metal material, with further filter dust; When adopting multilayer additional metal filter screen, each metal screen can adopt the arrangement mode that reduces successively along wind direction direction mesh to arrange, with filter dust to greatest extent.
Described metal screen can make pattern for convenience detach, regularly to pull down wiping or flushing.
In computing chip field of radiating, all can use metal and carry out transferring heat, such as use metal fin.Metal is except there being good thermal conductivity, also conductive.When using as fin, the thermal conductivity of metal is required for us, helpful to heat radiation.The electric conductivity of metal then can make fin bring electrostatic charge because of antenna effect.The dust of Electrostatic Absorption can cover and cause heat radiation bad on a heat sink.For notebook computer, the upper covering metal fin of CPU, is connected with radiating fin by metal heat pipe.The Main Function of this structure is heat radiation, also can dust stratification on radiating fin, but dust stratification is negative interaction, and heat radiation can be caused bad.So when using as fin, the electric conductivity of metal can bring negative interaction.
The present invention utilize the electric conductivity of metal electrostatic from fin conductive to the metal screen of cabinet air intake vent.Then dust can be deposited on the metal screen of air intake vent because of the suction-operated of electrostatic, and no longer toward cabinet inside motion, therefore reduces the dust on the electronic device of cabinet inside.Simultaneously, the dust of device absorption of the present invention also can neutralize the electrostatic of generation, thus reduces the carried charge on radiating tube and radiating fin, when air intake vent own does not bring dust into, more difficultly on radiating tube and radiating fin gather dust, ensure good radiating effect.Therefore, device of the present invention transforms this negative interaction of metal fin static electrification in computing chip field of radiating, has both carried out dedusting to cabinet and has kept cabinet inside to clean, also removed the electrostatic of generation, create unforeseeable technique effect, overcome technology prejudice.
In sum, relative to prior art, electrostatic precipitation dust guard of the present invention possesses following beneficial effect:
The first, solve the problem that cabinet inside electronic device is corroded by dust, and it is blocked to solve anti-dust filter mesh in prior art, the problem that radiating effect declines, ensure that the clean and tidy of cabinet inside, also strengthen the radiating effect of cabinet.
The second, utilize the electrostatic precipitation that the antenna effect of metal fin produces, only need static guiding on metal screen, can not expend extra electricity, be the process of a refuse reclamation.
3rd, with low cost, structure is simple, saves space, without the need to special processing mode, can carry out repacking upgrading voluntarily to cabinet.
