The purpose of this utility model is to provide a kind of distribution box top cover, will can accumulated in time hot empty at the top of distribution box
Gas is discharged, and promotes the air circulation in distribution box, improves 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 is provided with ventilating fan, institute be located in the ledge plate on substrate, and the side seal board located at ledge plate two opposite sides, substrate
State the other two opposite sides of ledge plate and be equipped with positive shrouding with substrate connection, two pieces of positive shrouding outer walls are equipped with and distribution box top cover
It is equipped with that multiple shapes are identical in the casing that inside is communicated, two casings, the dividing plate of different sizes, between leaving between adjacent separator
Away from dividing plate includes plate one, the plate two of orthogonal connection, and the plate one of multiple dividing plates is each perpendicular to positive shrouding and set, many
The plate two of individual dividing plate is each perpendicular to be connected to pressure fan, induced-draught fan on the setting of casing one end, the end of two casings.
By using above-mentioned technical proposal, enclosed by substrate and side seal board below ledge plate and set out separate space, substrate
On ventilating fan the hot-air in distribution box is led in the space, two casings respectively have ecto-entad blowing, by introversion
Outer suction wind action, with pressure fan balanced ventilation into distribution box top cover through casing, is sent into distribution box top cover by pressure fan
Air is discharged outside distribution box after being mixed with the hot-air in distribution box top cover by induced-draught fan.Multiple shapes are identical, not of uniform size
Casing is separated into multiple ventilating ducts by dividing plate, because dividing plate is formed by connecting by mutually perpendicular plate one and plate two, so by phase
The ventilating duct that adjacent dividing plate is surrounded is into " L " shape, by the entrance concentrated setting of multiple " L " shape ventilating ducts in casing one end, beneficial to sending
The connection of blower fan or induced-draught fan, the outlet of multiple " L " shape ventilating ducts is distributed on casing length direction, beneficial to distribution box top cover
Interior uniform air-out.
It is preferred that, offered on two blocks of positive shroudings with casing length and width identical long through-hole, provided with many in long through-hole
Individual supporting plate.
By using above-mentioned technical proposal, by setting supporting plate to be opened up to improve positive shrouding at long through-hole in long through-hole
Structural strength.
It is preferred that, the plate one is corresponded with the supporting plate, and corresponding plate one is in same flat with supporting plate
In face.
By using above-mentioned technical proposal, every piece of plate one is located in same plane with corresponding supporting plate, can be reduced
Supporting plate is hindered air flow, is caused air flow through more smoothly.
It is preferred that, two casings are set to open, and the open side of casing inside distribution box top cover with communicating.
By using above-mentioned technical proposal, the side of two casings towards positive shroudings is set to open, on the one hand can make company
The casing air-out for picking blower fan is smooth, and the casing air draught of connection induced-draught fan on the other hand can be made smooth.
It is preferred that, the plate one of multiple dividing plates is placed equidistant, and the plate two of multiple dividing plates is also equidistantly set
Put.
By using above-mentioned technical proposal, multiple plates one, multiple plates two are placed equidistant, can make it is multiple by it is adjacent every
Air mass flow of the ventilating duct that plate is surrounded in corresponding position is roughly the same, enables the casing balanced ventilation of connection pressure fan, makes connection
The casing of induced-draught fan can uniform air draft.
It is preferred that, the dividing plate also includes arc, and arc one end is connected with plate one, and the other end connects with plate two
Connect.
By using above-mentioned technical proposal, plate one and plate two are connected by arc, junction can smooth transition, sky
Gas flows out-of-date more unimpeded on dividing plate, is obstructed smaller.
It is preferred that, the cross sectional shape of the substrate is trapezoidal, and the inclined side on substrate both sides is put down with the two sides of ledge plate
OK.
By using above-mentioned technical proposal, the substrate two sides of trapezoid cross section are parallel with ledge plate two sides difference, then he
The passage surrounded between them apart from equal, is not likely to produce vortex everywhere, contributes to the smooth of air-flow to pass through.
It is preferred that, the substrate extends on the inclined side of the side of the pressure fan to the substrate center direction
Provided with deflector, deflector be arranged in parallel with the substrate inclined side where it.
By using above-mentioned technical proposal, when the casing for being provided with pressure fan is dried into distribution box top cover, air-flow via
The guiding of deflector tilts upward flowing, so as to avoid at the ventilating fan on substrate just in up hot-air, it is possible to decrease to heat
The up influence of air.
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.
