Abstract
The invention relates to a power distribution box, comprising a box body. The box is characterized in that the box body is internally provided with a fan, and the box body is provided with an air-out hole of the fan and a plurality of air-intake holes. The box body is also provided with a plurality of trough-type sealing plates. The trough-type sealing plates respectively cover the air-out hole and the air-intake holes on the box body. The upper end of the trough-type sealing plate is sealed. The lower end of the trough-type sealing plate is open. The trough-type sealing plates and the side wall of the box body form air-intake channels of the air-intake holes. The power distribution box is good in heat radiation and waterproofness.
Description
Technical field
The present invention relates to technical field of electric appliances, specifically a kind of distribution box.
Background technology
Usually distribution box can be used in factory work process; and the distribution box used normally is positioned at outdoor; for rainproof damp proof; distribution box mostly does comparatively seal; this heat radiation for the electronic component in distribution box is very unfavorable; and when running into the situation that rainwater infilters in distribution box, also more difficult drying.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of heat radiation water resistance good distribution box.
The technical solution adopted in the present invention is: provide a kind of distribution box, comprise casing, fan is provided with in described casing, casing is provided with air outlet hole and several air intake through holes, casing is also provided with several grooved sealing plates, described grooved sealing plate covers air outlet hole on casing and air intake through hole respectively, grooved sealing plate upper end closed, grooved sealing plate lower ending opening, grooved sealing plate and wall box form the air intake passage of air intake through hole.
After adopting above structure, distribution box of the present invention forms negative pressure by operating in casing of fan, exogenous wind enters in casing via air intake passage, air intake through hole, and by air outlet hole air-out, make the environment forming air flowing in casing, good effect played to the heat radiation of electronic component, grooved sealing plate vibrational power flow make water be not easy to enter in casing from air intake through hole, structure is simple, and water resistance is good.
As improvement, described air intake through hole is provided with screen pack, impurity that can be larger in filtering inlet air, the electronic component in protection casing.
Accompanying drawing explanation
Fig. 1 is the structural representation of distribution box of the present invention.
In figure, 1, casing, 1.1, air intake through hole, 1.2, air outlet hole, 2, grooved sealing plate, 3, fan.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1, distribution box of the present invention, comprise casing 1, top in casing 1 is provided with fan 3, the casing 1 at fan 3 place is provided with air outlet hole 1.2, the wind being convenient to fan 3 blows out casing 1 from air outlet hole 1.2, the bottom of casing 1 is provided with several air intake through holes 1.1, casing 1 is also provided with several grooved sealing plates 2, grooved sealing plate 2 is located on the lateral wall of casing 1, grooved sealing plate 2 covers air outlet hole 1.2 and the air intake through hole 1.1 of the fan 3 on casing 1 respectively, the upper end closed of grooved sealing plate 2, the lower ending opening of grooved sealing plate 2, namely the sidewall of grooved sealing plate 2 and casing 1 forms the air intake passage of air intake through hole 1.1.Air intake through hole 1.1 on casing 1 of the present invention is provided with screen pack.
The present invention is when specifically using, negative pressure is formed by operating in casing 1 of fan 3 in distribution box, exogenous wind enters in casing 1 via air intake passage, air intake through hole 1.1, and by air outlet hole 1.2 air-out, make the environment forming air flowing in casing 1, good effect is played to the heat radiation of electronic component, in addition, the vibrational power flow of grooved sealing plate 2 makes water be not easy to enter in casing 1 from air intake through hole 1.1, and structure of the present invention is simple, and water resistance is good.
Claims (2)
