Abstract

The utility model discloses an outdoor LED display screen installation box, which comprises a box body, and an embedded air inlet/outlet and a convex heat dissipation hole which are arranged on the side wall of the box body. A lower inclined baffle and an upper inclined baffle stretch out from the air passage of the air inlet/outlet in the opposite directions and divide the air passage to ensure that the air passage has no straight passage. The convex heat dissipation hole comprises an outer rain baffle and side plates, wherein the outer rain baffle protrudes outward from the side wall of the box body and extends downward, and the side plates are arranged between the two sides of the outer rain baffle and the side wall of the box body. An air window is arranged on the side wall of the box body at a position corresponding to the outer rain baffle. An inner rain baffle is arranged on the lower edge of the air window. The inner rain baffle comprises vertical rain barrier strips. The lower edge of the vertical barrier strips are connected with the lower edge of the air window. The upper edge of the vertical rain barrier strips is turned over and extends towards the direction of the outer rain baffle. Compared with the prior art, the utility model has the advantages that the heat dissipation effect is good, the anti-backward-rainwater-pouring capacity is strong and the installation box can effectively withstand heavy wind and rain.

Description

A kind of outdoor LED display install bin

Technical field

The utility model relates to the electric equipment install bin, relates in particular to a kind of outdoor LED display install bin.

Background technology

Present outdoor LED display is widely used in station terminal, commercial medium street, scenic spot, park etc. and locates.Outdoor owing to being located in, water-tight device is proposed high requirement.Power supply heat sinking mouth on the electric fan exhaust outlet on LED display install bin top, the air inlet of install bin bottom, the install bin sidewall all has waterproof construction, and Fig. 2,4,6 shows the cut-open view of exhaust outlet, louvre, air inlet respectively.Their common features are that air flue is straight unobstructed, and when having typhoon to attack in the coastland, it is weak that these waterproof constructions seem, exists rainwater to pour in down a chimney phenomenon, causes internal wetted, and life-span of product has seriously been shortened in harm such as short circuit.

The utility model content

The utility model is the problems referred to above that will solve prior art, proposes a kind of high wind rain of taking precautions against, outdoor LED display install bin that radiating effect is good.

For solving the problems of the technologies described above, the technical scheme that the utility model proposes is: a kind of outdoor LED display install bin, comprise casing, being located at embedded on the wall box advances/exhaust outlet, raised type louvre, describedly advance/air flue of exhaust outlet is tilted to, air flue comprises vertical plane, dip plane and two sides, the downward-sloping baffle plate that has a down dip that extends of air flue vertical plane, the air flue dip plane is inclined upwardly and extends the baffle plate that tilts, the baffle plate that has a down dip is cut apart air flue with the baffle plate that tilts, and makes the tortuous no beeline channel of air flue; Described raised type louvre comprises by the outer outer weather shield that protrudes and extend downwards on the wall box, is located at the side plate between outer weather shield both sides and the wall box, and the outer weather shield place of wall box correspondence has transom window, and the transom window lower edge is provided with interior weather shield; Weather shield comprises vertical wiper bar in described, and vertically the lower edge of wiper bar is connected with the transom window lower edge, and vertically the outside weather shield direction turnover in the upper edge of wiper bar is extended.

In one embodiment, a horizontal-extending portion is extended to air flue vertical plane direction in the upper edge of the described baffle plate that tilts.Described horizontal-extending portion and the described baffle plate that has a down dip are overlapping to some extent in vertical.

Compared with prior art, the utility model radiating effect is good, and the anti-rainwater ability of pouring in down a chimney gets by force, can take precautions against high wind rain effectively and blow.
