Specific embodiment

The present invention will be further described with reference to the accompanying drawings and detailed description.

Shown in as shown in Figure 1 to Figure 4,

A kind of distribution box, including

Heat radiation box 1, exhaust cabinet 2, distributing box 3 and the distribution box door being arranged on distributing box;

Diaphragm plate 31 is equipped in the distributing box, diaphragm plate will be separated into upper air cavity 3a and be in inside distributing box Distribution chamber 3b below air cavity, distributing box be equipped with several the first air inlet 3c being connected to distribution chamber and several and distribution+ First venthole 3d of chamber connection, heat radiation box are equipped with several and one-to-one second air inlet 1a of the first venthole, the One venthole is connected to corresponding second air inlet;

The exhaust cabinet is equipped with third air inlet 2a and third venthole, is equipped with water-proof fan in fumer body, prevents The air guide direction of Water fan is by third air inlet to third venthole, and the outgassing direction of third venthole is horizontal, heat radiation box It is equipped with the second venthole 1b, the second venthole is connected to third air inlet;

The distributing box is equipped with the enterprising stomata 3e being connected to the upper air cavity and upper venthole 3f being connected to upper air cavity, Heat radiation box is equipped with the interstitial hole 1c being connected to upper venthole.

Electrical equipment can be only fitted in distribution chamber.Water-proof fan continues working, and forms two kinds of radiating airflows.The first gas Stream is direct radiating airflow, from the external world the first air inlet 3c, distribution chamber 3b, the first venthole 3d, the second air inlet 1a, heat dissipation Box house, the second venthole 1b, third air inlet 2a are simultaneously finally discharged from third venthole, and direct radiating airflow is directly over Distribution chamber more can directly take away internal heat, persistently radiate;Second air-flow is indirect radiating airflow, from outer Boundary through inside enterprising stomata 3e, upper air cavity 3a, upper venthole 3f, interstitial hole 1c, heat radiation box, the second venthole 1b, third into Stomata 2a is simultaneously finally discharged from third venthole.

The diaphragm plate is equipped with several heat conducting bars 32 across diaphragm plate, and heat conducting bar upper end is in air cavity, thermally conductive It is intracavitary that bar lower end is in distribution, seals and fixes between heat conducting bar and diaphragm plate.The intracavitary relative temperature highest of distribution, because electrically setting It is standby all wherein, and indirectly radiating airflow when by upper air cavity, can also take away by heat conducting bar transmit in distribution chamber Heat, improve heat dissipation effect.

The enterprising stomata and upper venthole are coaxially arranged, and heat conducting bar is equipped with thermally conductive sheet 33, and thermally conductive sheet is in air cavity Interior, upper air axially bored line is parallel to thermally conductive sheet.Thermally conductive sheet can increase the time of contact with indirect radiating airflow, further be promoted Heat-sinking capability, enhances heat dissipation effect.

Each first air inlet is from top to bottom sequentially arranged, perpendicular between the first air inlet and heat radiation box bottom of bottom Directly apart from 1/5th for heat radiation box height to a quarter.It can prevent ponding from entering distribution chamber from the first air inlet.

The sink of upper end opening is equipped at the top of the heat radiation box, sink includes groove bottom wall 41 and sequentially connected left side wall 42, front side wall 43, right side wall 44 and rear wall, sink is interior to be equipped with floating body 5, and front side wall lower part is equipped with draining seam 43a, sink top Equipped with the lid 6 for covering sink opening, lid includes cover board 61 and web plate 62, and heat radiation box, which is equipped with, can seal the first air inlet Vertical closure plate 7, vertical closure plate and heat radiation box be slidingly sealed cooperation, and vertical closure plate is equipped with several one-to-one with the first air inlet Venthole 7a, venthole are connected to corresponding first air inlet, and cover board is connect by connector 8 with floating body, connector and front side wall It is slidably connected, connector glide direction is vertical, is gone up on vertical closure plate equipped with blow vent 7b, front side wall is equipped with limit body 431;It is floating When body contacts bottom of gullet, venthole is connected to corresponding first air inlet, and vertical closure plate seals blow vent;Floating body contacts limit body When, enterprising stomata is connected to blow vent, and vertical closure plate seals each first air inlet.

Direct radiating airflow can first pass through venthole 7a before entering the first air inlet 3c.

Other than feature described in background technology, there are one features for electrical equipment, should not exactly be in the long period In environment more than aqueous vapor, especially the air of excessive rainwater or excessive moisture to be avoided to continue into distribution box, otherwise hold and lead Send a telegraph road, the electrical equipment service life seriously shortens, be also easy to cause short circuit.Conventional distribution box, once encounter the rainy day (very little, when Between very short rain ignore because influence time is short and influences small), the air of external extreme humidity, which will be flowed through constantly, electrically to be set Standby, this is totally unfavorable.In addition, rainwater is also easy to enter distribution chamber, it is easier to go wrong.

And in the present embodiment, when not raining or rainy, but the feelings of rainwater very little (very little, time very short rain) Under condition, rainwater can enter sink by web plate, but the water in sink will not be accumulated, and quickly discharge can be all stitched from draining.It is straight at this time Connect radiating airflow proper flow, indirect radiating airflow be blocked (direct radiating airflow effect is strong, thus direct radiating airflow just Often when flowing, it is little that indirect radiating airflow is blocked influence).

And once rainfall is slightly larger, draining seam will have little time Quick drainage, floating body can rise at this time, drive vertical closure plate on It rises, floating body can touch limit body, and enterprising stomata is connected to blow vent at this time, and vertical closure plate seals each first air inlet, radiate indirectly Air-flow constant flow can be radiated indirectly, while can be avoided rainwater and a large amount of aqueous vapors enter distribution chamber, and completion is cut automatically It changes, also, cools down as caused by rainfall, the heat radiation function of a part of directly radiating airflow can be made up.After rain stops, in gravity Under effect, each structure resets.

Limit body halftone contact screen bottom, web plate are horizontally disposed.

The web plate and cover board are hinged;When floating body contacts bottom of gullet, a side frame of the web plate far from cover board is on left side wall top Portion;When floating body contacts limit body, a side frame of the web plate far from cover board is at the top of left side wall.When floating body rises, web plate is also to rise , so buoyancy also needs to overcome the whole gravity of web plate, and in the present embodiment, using lever principle, web plate is far from cover board Side always frame at the top of left side wall, it is only necessary to the power of very little is provided, the side that web plate closes on cover board can be smoothly lifted.
