Abstract
The utility model discloses an exhaust passage protection structure for an outdoor cabinet/box top, which is characterized in that a baffle welded on the passage is of a V shape, both sides of the passage are provided with two symmetrical air outlets; and air outlet hinges are arranged above the passage through hinge shafts. The protection structure has the advantages that a deflector is arranged on the passage, which avoids the direct impact loss of gas to the top of the passage; and the air outlet hinges are arranged at an angle of 45 degrees, which ensures that the air outlet hinges are easier to be blown up, thereby ensuring that inside hot air is easier to get out. When a fan stops working, the air outlet hinges can automatically fall off to completely cover the air outlets, prevent dust outside a cabinet from entering the cabinet, and avoid the heat inside the cabinet from dissipating in cold winter season. Certain steps are reserved at the air outlets on both sides of the passage, thereby preventing external rainwater from flowing into the cabinet through the passage. The exhaust passage protection structure for the outdoor cabinet/box top completely achieves the IP55 class protection requirement in GB4208 standard.
Description
Technical field
The utility model relates to a kind of novel air duct safeguard structure that is used for outdoor cabinet/case top, belong to outdoor cabinet/case manufacturing technology field.
Background technology
It is directly the air-out loose-leaf to be blown open mostly that existing rack/case adopts the case top air-out air channel protection of ventilation and heat, its weak point is: gas is directly aimed at the air-out loose-leaf and is blown out in the time of air-out, the impact loss of air-flow is too big to influence the shedding of hot-air of rack inside, do not meet the aerology principle, when the air-out loose-leaf blows afloat rear fan and decommissions sometimes, the air-out loose-leaf can not fall timely, causes the dust of outside to be easy to enter in the rack.Stipulated the requirement of IP degree of protection in the GB4208 standard, active equipment is had relatively high expectations to residing working environment usually, requires to reach the IP55 rank and requires standard.The safeguard structure of obvious existing air-out loose-leaf can not meet the demands.
Summary of the invention
The purpose of this utility model is at above-mentioned defective, a kind of air channel safeguard structure that is used for outdoor crate/cabinet is proposed, its air channel is in the shape of the letter V, it can effectively overcome above-mentioned existing in prior technology outdoor cabinet/box top and enter dust easily, winter, heat easily scattered and disappeared, and the air-out loose-leaf is not easy to fall defectives such as lid is not tight.
Technical solution of the present utility model: its structure is to weld the deflector of the shape that is in the shape of the letter V on the air channel, has the exhaust vent of two symmetries in the both sides in air channel; The air-out loose-leaf passes through hinge axis
Be installed in above the air channel.Guiding device of welding makes distributing that gas is more prone on the air channel.With the oblique placement at 45 of air-out loose-leaf, make being blown afloat that the air-out loose-leaf is more prone to.
Inside on rack casing top is equipped with axial flow blower, pushes up outside installation shaft flow fan corresponding section at the rack casing this air channel is installed.
Advantage of the present utility model: the both sides in air channel are tilted to place two air-out loose-leaves that thin aluminum sheet is done respectively, respectively two air-out loose-leaves are fixed on above the air channel with two thin axles, are more prone to distribute thereby the flange of doing a water conservancy diversion on the air channel makes air-out more meet the heat that hydromechanical principle makes rack inside.When the blower fan of rack inside begins to move, blower fan blows the air-out loose-leaf above the air channel open, the hot-air of rack inside is blown out outside the rack, and the inner air-flow that forms the negative pressure outside of rack will be above cabinet door shutter and enter rack inside by screen pack.Form a circulation like this.Owing on the air channel, add the device of a water conservancy diversion, avoided the direct impact loss of gas to the top, air channel, the oblique placement at 45 of air-out loose-leaf makes the air-out loose-leaf be more prone to blow afloat, thereby inner hot blast is more prone to away.The wind of having avoided early stage air channel is gone out and impact loss is excessive along a straight line, and the wind in the air channel blows out under v-shaped structure now.Aerodynamic principle and be beneficial to shedding of heat more.The air-out loose-leaf can fall automatically air outlet is covered completely when blower fan stops to move, prevents that the dust of rack outside from entering rack inside, and avoid the rack internal heat to run off cold in the winter time season.And the air outlet in the both sides, air channel leaves certain step.Thereby prevent that outside rainwater from flowing into rack inside by the air channel.Reach the requirement of shelter of IP55 level in the GB4208 standard fully.
Description of drawings
Accompanying drawing 1 be blower fan when not moving the air-out loose-leaf above the air channel be in the schematic diagram of closed condition.
Accompanying drawing 2 is view that the air-out loose-leaf on both sides, air channel was blown afloat after blower fan began to move.
Among the figure 1 is air channel, the 2nd, air-out loose-leaf, the 3rd, hinge axis.
The specific embodiment
Contrast accompanying drawing, its structure are the deflectors that welds the shape that is in the shape of the letter V on the air channel 1, have the exhaust vent of two symmetries in the both sides in air channel; Air-out loose-leaf 2 is installed in above the air channel 1 by hinge axis 3.
Guiding device of welding makes distributing that gas is more prone on the described air channel 1.
With the oblique placement at 45 of air-out loose-leaf, make being blown afloat that the air-out loose-leaf is more prone to.
Inside on rack casing top is equipped with axial flow blower, pushes up outside installation shaft flow fan corresponding section at the rack casing this air channel is installed.
Dustproof: when blower fan stopped to move, the air-out loose-leaf covered the air outlet in air channel fully, and the dust of outside can not enter.The air-out loose-leaf is blown afloat when blower fan begins to move, and outwards the dust of blowing outside is difficult for being blown in the rack.
Waterproof: when a spot of rainwater enters rack casing top by the top cover shutter,, between bottom, air channel and casing top, stamped fluid sealant owing to be provided with certain step in the ducting outlet bottom.Rainwater can not enter rack inside.
Claims (2)
1, is used for the air channel safeguard structure that outdoor cabinet/case pushes up, it is characterized in that on the air channel, welding the deflector of the shape that is in the shape of the letter V, have the exhaust vent of two symmetries in the both sides in air channel; The air-out loose-leaf is installed in above the air channel by hinge axis.
2, the air channel safeguard structure on a kind of outdoor cabinet according to claim 1/case top is characterized in that the oblique placement at 45 of air-out loose-leaf.
