Abstract
The utility model relates to an outdoor air cooling low-voltage power distribution box which comprises a cabinet body and a cabinet door. A rainproof cover is disposed at the top end of the cabinet body. The left side and the right side of the cabinet body are both hollow double-layer structures. An outer layer of each double-layer structure is provided with a rainproof groove. The rainproof groove is provided with uniformly and densely distributed air holes. An inner layer of each double-layer structure is provided with two heat radiation grooves, wherein heat radiation holes are uniformly and densely distributed in the heat radiation grooves. Heat radiation apparatuses are disposed inside the cabinet body and are disposed between the two heat radiation grooves in the left side and between the two heat radiation grooves in the right side respectively. A shelf is disposed in a lower part of the cabinet body. A ventilation opening is disposed in a lower end of the cabinet body. According to the outdoor air cooling low-voltage power distribution box, good encapsulation performance and heat radiation performance are ensured, water is prevented from flooding the power distribution and the rainwater is prevented from sprinkling into the power distribution box, and thus the service life of the power distribution box is prolonged.
Description
Technical field
The utility model belongs to low pressure equipment for power transmission and distribution, relates to a kind of outdoor air-cooled low-tension distribution box.
Background technology
Low-voltage distribution cabinet is arranged on indoor conventionally, and its construction packages is poor, cannot be used for outdoor installing and using, and has limited the scope of application of low-voltage distribution apparatus.While application out of doors, when running into rainy weather, in the situation that being flooded, water can enter power distribution cabinet inside from the shell gap of power distribution cabinet, element in power distribution cabinet is soaked in water, thereby causes electric equipment normally to move, also can cause serious potential safety hazard simultaneously.
The common object that adopts hermetic power distribution cabinet or realize anti-water logging at power distribution cabinet outer cover one bucker in prior art.
The general can that adopts of hermetic power distribution cabinet, is carrying out after electrical equipment assembling, cabinet door is sealed fixing.And electric elements in power distribution cabinet are in the time of workpiece, can produce a large amount of heats, cannot realize efficiently radiates heat.Solve heat dissipation problem even heat abstractor is set in full seal type distribution box, but this also requires the continuous operation of heat abstractor, causes the loss of energy.
At power distribution cabinet outer cover one bucker, because of water logging degree of depth difference, the air space difference of retaining above distribution cabinet.Under actual conditions, because of the reason of atmospheric pressure support water column, the air of power distribution cabinet top retains highly very little, that is to say, utilizes pressure principle cannot realize the object of anti-water logging completely at all.
Utility model content
Technical problem to be solved in the utility model is, overcome the shortcoming of prior art, a kind of outdoor air-cooled low-tension distribution box is provided, can guarantee good encapsulation and thermal diffusivity, and can anti-water logging and prevent that rainwater from swilling into distribution box inside, increase the life-span of distribution box.
In order to solve above technical problem, the utility model provides a kind of outdoor air-cooled low-tension distribution box, comprises cabinet and cabinet door, and cabinet top is provided with rain cover; Cabinet limit, left side and right edge are the double-decker of hollow, and double-deck skin is provided with rainproof groove, is evenly densely covered with air-vent on rainproof groove, and double-deck internal layer is provided with two radiating grooves, is evenly distributed with louvre on radiating groove; Cabinet inside is provided with heat abstractor, and heat abstractor is arranged on respectively between limit, left side and two radiating grooves of right edge, and in cabinet, bottom is provided with shelf, and cabinet door lower end is provided with ventilating opening.
The technical scheme that the utility model further limits is:
Aforementioned heat abstractor comprises fan and evaporator.
Aforementioned shelf is selected insulating heat-conduction material.
The distance of aforementioned shelf and cabinet bottom is 5cm-10cm.
Four limits of aforementioned cabinet door are provided with sealing strip.
The beneficial effects of the utility model are: the utility model adopts air-cooled method heat radiation, can reduce power consumption, and good heat radiation is provided; The cabinet of the utility model left and right sides is double layer design, the outer slotted eye that adopts, can reduce rainwater swills in cabinet, internal layer adopts radiating groove, can accelerate heat radiation, there is gap in inside and outside two-layer centre, can guarantee that rainwater does not enter in cabinet from internal layer, the rain phenomenon of swilling while effectively having avoided rainy weather; The utlity model has good encapsulation, and there is longer useful life.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Reference numeral: 1-rain cover, 2-cabinet, 3-cabinet door, the rainproof groove of 4-, 5-radiating groove, 6-heat abstractor, 7-ventilating opening, 8-shelf.
Embodiment
