Description
Technical field
The utility model is related to electrical equipment technical field, more particularly to a kind of distribution box top cover.
Background technology
When distribution box works, electric elements can distribute amount of heat, and these heats are in existing distribution box structure
It can not discharge in time, therefore after the distribution box work long period, these heats that can not be discharged in time will influence distribution box
Normal work, and consumption the energy also accordingly increase.
To solve the above problems, Publication No. CN201142526 Chinese utility model discloses a kind of power distribution panel
Top cover, including substrate and the ledge plate of ridge-roof type, the bottom of substrate are provided with exhaust fan, and ledge plate is buckled on substrate, ledge plate
Heat dissipation channel is reserved with the side wall formed between substrate.Because heat dissipation channel is more narrow, and ventilating fan promotes air
Negotiability is limited, and the heat produced in above-mentioned distribution box by electric elements is easily accumulated in arch after rising in the form of hot-air
It can not in time be discharged between cover plate and substrate, will if things go on like this cause temperature inside the box further to raise.
Utility model content
The purpose of this utility model is to provide a kind of distribution box top cover, can accelerate the row of the interior hot-air of distribution box top cover
Go out, improve distribution box radiating efficiency.
Above-mentioned purpose of the present utility model technical scheme is that：A kind of distribution box top cover, including
Substrate and being located in is set on the ledge plate in ridge-shaped on substrate, and the side seal board located at ledge plate two opposite sides, substrate
There is ventilating fan, ajutage is provided between the ledge plate and substrate, ajutage is located at the underface of ledge plate, and parallel to ledge
The ridge line of plate is set, and is provided with two exhausting holes on ajutage along its length, and distribution box top cover and company are stretched out in ajutage one end
Pressure fan is connected to, the other two opposite sides of ledge plate are equipped with the positive shrouding with substrate connection, two blocks of positive shroudings and are equipped with ventilation
Mouthful, two exhausting holes on ajutage are respectively facing ventilating opening at two and set.
By using above-mentioned technical proposal, by setting ajutage in distribution box top cover, and opened up on ajutage can
Hot-air in distribution box is incorporated into distribution box top by the ventilating fan on two exhausting holes dried respectively to both sides ventilating opening, substrate
After in lid, the air-flow for blowing to ventilating opening from ajutage drives hot-air to flowing at ventilating opening, and due to two rows from ajutage
The air-flow velocity of through hole blowout is very fast, and the hot-air flow velocity driven by ventilating fan is slower, two kinds of air-flow boundary different in flow rate
There is pressure difference in place, can accelerate the mixing of hot-air and pressure fan air-flow.
It is preferred that, the substrate cross sectional shape is trapezoidal, and the two sides of substrate are parallel with ledge plate two sides difference.
By using above-mentioned technical proposal, the substrate two sides of trapezoid cross section are parallel with ledge plate two sides difference, then it
Between the passage that surrounds everywhere apart from equal, be not likely to produce vortex, contribute to the smooth of air-flow to pass through.
It is preferred that, two pieces of deflectors are set in "eight" shape below two exhausting holes in the air-out pipe outer wall.
By using above-mentioned technical proposal, by setting two pieces of deflectors in "eight" shape below two exhausting holes, draw
The air-flow discharged from ajutage is led to flowing at the ventilating opening of both sides, also with the good effect of keeping out the wind, is prevented to a certain extent
The air-flow blown out from two exhausting holes blows down the hot-air drunk up by ventilating fan.
It is preferred that, two pieces of deflectors are 15 degree ~ 45 degree with horizontal plane angulation.
By using above-mentioned technical proposal, it can cause to blow out from warm-air pipe because the angle of deflector and horizontal plane is too small
Lift too high on air-flow, influence and the mixing of hot-air in distribution box top cover, and angle crosses conference and stops up at ventilating fan
Hot-air, so deflector and horizontal plane angle are set into moderate 15 degree ~ 45 degree.
It is preferred that, cover body one is covered with the ventilating opening on two blocks of positive shroudings, cover body one includes arc and bottom plate,
Bottom plate is located between arc bottom and positive shrouding, and projection covering ventilating opening of the arc on positive shrouding is set, on bottom sealing plate
Provided with multiple air vents.
By using above-mentioned technical proposal, the waterproof and dustproof at distribution box top cover ventilating opening can be improved by cover body one, is prevented
The performances such as toy, projection covering ventilating opening of the arc on positive shrouding, then dust, rainwater, fallen leaves etc. can not be from distribution boxs
Top and with ventilating opening with entering distribution box at height.
It is preferred that, cover body two is covered with the ventilating opening on two blocks of positive shroudings, cover body two includes sloping baffle, tilts
Baffle plate is below ventilating opening, and sloping baffle is provided with multiple air vents.
By using above-mentioned technical proposal, the waterproof and dustproof at distribution box top cover ventilating opening can be improved by cover body two, is prevented
The baffle plate being obliquely installed on the performances such as toy, cover body two is tilted down equivalent to by ventilating opening so that rainwater, dust, debris
Etc. being difficult to be blown into distribution box by ventilating opening by wind.
It is preferred that, two ventilating openings are directly long opening, and the length of ventilating opening is more than the 3/4 of positive shrouding length.
By using above-mentioned technical proposal, the length of limitation ventilating opening is more than the 3/4 of positive shrouding length so that ventilating opening
Length as close possible to positive shrouding length, to increase the air mass flow at ventilating opening, so as to improve scavenging efficiency.
It is preferred that, multiple supporting plates vertical with the positive shrouding are equidistantly provided with two ventilating openings.
By using above-mentioned technical proposal, by being equally spaced multiple supporting plates in ventilating opening, to increase positive shrouding
Structural strength at ventilating opening.
In summary, the utility model has the advantages that：
1st, the hot-air in distribution box top cover can be discharged in time, may additionally facilitate the air flow in distribution box, be conducive to
The cooling of electric elements in distribution box, fundamentally solves the problem of distribution box heat is gathered；
2nd, pressure fan be sent into outside distribution box distribution box air themperature it is lower than the air themperature in distribution box, therefore necessarily
The situation that heat is gathered in distribution box is alleviated in degree.
