Abstract
The invention relates to an outdoor electrical control cabinet, especially relates to an outdoor electrical control cabinet with a cooling device and an operating method for a filter fan thereof. The outdoor electrical control cabinet comprises a cabinet body, an air inlet is arranged on the upper part of the cabinet body, an air outlet is arranged on the bottom part of the cabinet body, filter screens are embedded in the cabinet body at the outside of the air outlet and the air inlet, and a motor arranged on the air outlet is a forward-counter-rotating filter fan. According to the invention, only one filter fan and the mounting position are changed, all of the other parts are unchanged, the cooling effect can not be influenced at all, the probability that the dusts outside enter in the cabinet is greatly reduced, and the application prospect is wide.
Description
Technical field
The present invention relates to a kind of outdoor electrical control cabinet, particularly relate to a kind of outdoor electrical control cabinet carrying heat abstractor and the method for work of filtering blower fan.
Background technology
The heat radiation of electric control cabinet generally adopts filter fan, industrial air-conditioning device, heat exchanger etc.Outdoor electric cabinet considers cost, nobody guards the consideration with safe antitheft specially, does not generally adopt industrial air-conditioning device and heat exchanger, generally adopts the method for fan cooling.
Because hot-air is lighter than cold air, in cabinet, air flow is general from lower to upper.Therefore, under normal circumstances, should using the below of the Qianmen of cabinet or sidewall paneling as air inlet, top is as exhaust outlet.If undesirable at work-yard environment, containing dust, mist of oil, aqueous vapor etc., that just should select filtration blower fan, and prior art is all select filter grid, to prevent dust, mist of oil, aqueous vapor etc. from entering control cubicle at the air inlet filtering blower fan.But because be in negative pressure state during electrical control cubicles air draft always, single gas flow direction makes dust enter in electrical control cubicles with air-flow from the various gaps such as electrical control cubicles crack between a door and its frame, be adsorbed on for a long time on the filter screen of import and export, final and filter screen tied up in knots simultaneously, be difficult to remove.
Summary of the invention
The object of the present invention is to provide a kind of self radiation type outdoor electrical control cabinet and filter the method for work of blower fan, overcoming dust in prior art, defect that aqueous vapor, corrosive substance can not be completely isolated the air inlet at control cubicle.
For achieving the above object, the technical scheme taked of the present invention is: comprise cabinet, and described cabinet top has air inlet, and bottom has air outlet, cabinet outside air outlet and air inlet is inlaid with filter screen, and the motor that described air outlet place installs is that blower fan is filtered in rotating.
In such scheme, the whole outside of described cabinet is all coated with sealing skin.
In such scheme, the order number of described filter screen is greater than 100 orders.
In such scheme, the lower end of described cabinet is also provided with base.
Present invention also offers the method for work that a kind of self radiation type outdoor electrical control cabinet air inlet filters blower fan, stop 30s after first rotating forward 60 points, and then stop 30s after the 30s that reverses, cycle operation like this.
Beneficial effect of the present invention: the present invention has only changed a kind of filtration blower fan and installation site thereof, other parts are all constant, cooling effect lacks at all unaffected, greatly can also reduce the probability that external dust impurity enters Electric Appliance Cabinet, be with a wide range of applications.
Accompanying drawing explanation
Fig. 1 is the structural representation of apparatus of the present invention.
In figure: 1. cabinet; 2. air inlet; 3. filter screen; 4. air outlet; 5. base.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in detail.
As shown in Figure 1, a kind of self radiation type outdoor electrical control cabinet of the present invention, comprises cabinet 1, described cabinet 1 top has air inlet 2, bottom has air outlet 4, and the cabinet outside air outlet 4 and air inlet 2 is inlaid with filter screen 3, and the motor that described air outlet 4 place installs is that blower fan is filtered in rotating.Preferably, the whole outside of described cabinet 1 is all coated with sealing skin, improves the sealing property of electrical control cubicles, prevents dust from entering into electrical control cubicles inside when electrical control cubicles internal negative pressure from the gap of electrical control cubicles outside.Preferably, the order number of described filter screen 3 is greater than 100 orders, improves filter effect, reduces fine dust particles and enters electrical control cubicles from inlet and outlet.Preferably, the lower end of described cabinet 1 is also provided with base 5.
Operation principle of the present invention is: filter after blower fan first rotates forward 60 points and stop 30s, and then stop 30s after the 30s that reverses, cycle operation like this.Because the electrical control cubicles of this equipment comparatively greatly, is dispelled the heat and is not substantially a problem in space in design.When blower fan rotates forward (to canyon), keep malleation in control cubicle, the gap air-flow of control cubicle is outwards blown, and dust cannot enter from gap.The object of fan reversion (to blowing up) allows the dust being adsorbed on electrical control cubicles Inlet Network outer surface can be reversed air-flow blowout in time, the dust being adsorbed on filter screen outer surface is just blown away in time when not sticking together with filter screen, decrease the chance that itself and filter screen tangle, what ensure that into, air draft is unimpeded, and effectively prevents entering of dust.
Through above transformation, the dust of the interior accumulation of electrical control cubicles obviously reduces, electrician's every 15 days clean electrical control cubicles before transformation, and its internal dust is a lot, and transform within latter 6 months, do not do clean all very clean.Simultaneously due to enter air draft smooth and easy after, the internal temperature of electrical control cubicles obviously reduces, and runs for two years so far from transformation, and all do not occur to crash and the phenomenon of the electric elements damages such as CPU, equipment failure rate obviously reduces.
