Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows the composition related with the utility model.
Embodiment 1
A kind of low-voltage distribution cabinet as depicted in figs. 1 and 2 has to install electronics member device including babinet, in the babinet
The inner cavity of part, the babinet is by top plate, bottom plate, front side board（It is not shown）, back side panel, left plate, right plate composition, the front side
Plate, back side panel, left plate, right plate are respectively provided with hypostracum 1 and outer shell 2, between the hypostracum 1 and outer shell 2 have every
Gap 3 is sowed discord, average mark is furnished with several first ventholes 4 on the hypostracum 1, and average mark is furnished with several on the outer shell 2
Two ventholes 5, first venthole 4 are mutually staggered with orthographic projection of second venthole 5 on same perpendicular, the top
The middle position of plate is equipped with the first ventilation hole 6, and the first fan blowing dried straight down is equipped at first ventilation hole 6
61。
Arrow instruction direction in Fig. 1, is that route is illustrated in the flowing of gas；First fan blowing is located at centre, gas
Flowing should squeeze flowing simultaneously to four sides, therefore also portion gas is from front side board or back side panel
It flows away in first venthole 4, but this two-part gas flowing signal route is not shown in Fig. 1.
The operation principle of the present embodiment is that back side panel and the left and right side plate of babinet may be incorporated for installation electronic component,
Front side board hingedly forms chamber door with left plate or right plate；Certainly in other embodiments or other side plate
Chamber door is hingedly formed for hinge, belongs to conventional mounting structure, no longer repeats herein；Four side plates of babinet be all provided with being set to every
The structure of gap 3 is sowed discord, the first 4 holes of ventilation on hypostracum 1 are set, second venthole 5, and the first venthole 4 are set on outer shell 2
Mutually staggered with the second venthole 5 so that after dust is externally entering the second venthole 5, because of dislocation setting and be not easy into
Enter in the first venthole 4；First ventilation hole 6 and the first fan blowing 61, the first blowing are set in the middle position of box roof
The air of external wind is blown into inner cavity by fan 61, and outside air forms air pressure, the heat being pressed down against in the middle part of inner cavity in inner cavity
Air makes hot-air be discharged into the first venthole 4 from four side plates, heat is taken away with this；Simultaneously under the action of air-flow,
It is further that dust is avoided to enter in inner cavity from the first venthole 4；It, not only can be effective using the design of inside and outside bivalve layer
Reinforcement low-voltage distribution cabinet dirt exclusion capabilities, anticollision, the shatter-resistant protective capability of low-voltage distribution cabinet, effective protection can also be enhanced
Internal electronic component can preferably work.A kind of low-voltage distribution cabinet of the present embodiment, the first air-out fan are constantly brought into
Extraneous low-temperature airflow；Internal high-temperature gas is squeezed out, so as to take away a large amount of heat, radiating rate is faster, more efficient.

Plate 41 is connected to the upside of the first venthole 4, and arc opening is downward.The setting of arc directing plate 41 avoids the first fan blowing
61 wind blown down are directly entered in the first venthole；Meanwhile air pressure inside, in cycle, thermal current againsts side wall from the bottom up
Also be more prone to be captured by arc directing plate 41 during rising, hence into the first venthole 4, be more prone to make heat with
It radiates the circulating system discharge inner cavity of air pressure inside.
In the present embodiment, the described one end of first ventilation hole 6 far from inner cavity is equipped with filter screen 7.Avoid dust logical from first
Enter in inner cavity with the exhausting of fan in air holes 6.
In the present embodiment, filter screen 7 is equipped in first venthole 4.Further dust is avoided from the first ventilation hole 4
It is middle to enter inner cavity.
Embodiment 2, the present embodiment 2 and embodiment 1 the difference lies in：
As depicted in figs. 1 and 2, the middle position of the bottom plate is equipped with the second ventilation hole 8, is set at second ventilation hole 8
There is the second fan blowing 81 dried straight up.Second fan blowing 81 is dried straight up, and the first fan blowing 61 is vertical
Blowing downwards, and person dries mutually relatively, air-flow generates fierce collision, and internal gas is made to generate violent extruding and collision,
Accelerate speed to discharge from the first venthole 4, radiating rate is faster.The pneumatic flow signal route of embodiment 2 is not in Fig. 1
Display.
Using the above-mentioned desirable embodiment according to the utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real
