Abstract
The utility model provides a light emitting diode (LED) display screen provided with a fan air opening device. The LED display screen has a structure capable of preventing crawlers such as cockroaches from entering an LED box body so as to avoid damage to the box body and adverse influence of the crawlers on the box body. The LED display screen comprises a fan arranged on the box body, a connecting pipe is arranged at the air outlet of the fan, the connecting pipe is connected with a three-way pipe through a locking ring, the three-way pipe comprises a main pipe and branch pipes, and the branch pipes are perpendicular to the main pipe and connected with the connecting pipe; the inner wall of the main pipe is smooth; and an air inlet is formed in the box body and below the fan, and a cover with a net is arranged at the orifice of the air inlet. The LED display screen can effectively prevent the crawlers such as the cockroaches from entering the box body, prevent the crawlers from gnawing components on a circuit board in the box body, prevent crawler remains from being accumulated in the box body and improve the heat dissipation environment of an LED.
Description
Technical field
The utility model relates to a kind of LED display.
Background technology
LED display is formed by box body splicing.Because the LED thermal value is bigger, and can not in hot environment, work, thus at the back side of casing fan need be set, to strengthen heat radiation.
All there is this insect in the very suitable cockroach breeding of China's weather existence in the office space of various buildingss.Cockroach is liked weak thermal source, by it electromagnetic heat source, circuit board thermal source is had a passion for, and therefore, the LED casing of fan is installed, and becomes the place of living away from home of cockroach easily.Cockroach can climb into the LED casing along the inlet of fan, within it breeding.A large amount of cockroaches can damage electrical equipment in casing, and dead cockroach in casing, after corpse is piled up within it, have long-pending thermal effect, are unfavorable for very much the heat radiation of casing.In China south, the cockroach breeding is very fast, also is very rapidly so LED display is threatened.
The utility model content
The utility model technical matters to be solved is: a kind of LED display is provided, and it has a kind of structure that can prevent this type of cockroach reptile entering LED casing, avoids destruction and the adverse effect of reptile to casing.
In order to solve above-mentioned technical matters, the utility model proposes a kind of LED display that loads the fan tuyere device, comprises the fan that is located on the casing, and
Air outlet at fan has connecting pipe, and connecting pipe is connected with a three-way pipe through binding ring, and three-way pipe comprises to be responsible for and arm, and arm is vertical with the person in charge, and is connected with connecting pipe; Said person in charge's inner wall smooth;
On the casing, fan below be provided with air admission hole, the aperture of air admission hole is provided with the cover of band net.
Preferably: the aperture of said air admission hole is provided with swivel nut, and said cover is threaded with swivel nut.
Preferably: on the said person in charge, face on the said arm position and be provided with pore.
The beneficial effect of the utility model:
Compare prior art, the utility model is provided with a three-way pipe on the air port of fan, this three-way pipe inner wall smooth.Such structure can prevent that this type of cockroach reptile from being climbed in the casing by the air port of fan, and three-way pipe is fixed on the connecting pipe through securing member, and it is replaceable structure, use a period of time after, can remove and clean or change.The utility model technical scheme can prevent effectively that this type of cockroach reptile from getting into casing, prevents that them from biting gnawing of components and parts on the casing interior circuit board, and prevents the accumulation of reptile corpse in casing, improves the heat dissipation environment of LED.Owing to be responsible for the wall face arm, the air-flow that can rebound causes a part of hot-air can be in three-way pipe back and forth; Influence radiating effect, therefore, at the above-mentioned pore that is provided with of this wall; Help preventing the amplitude of air-flow resilience; Part hot gas is directly discharged from pore, other above being responsible for below discharge, and then increase radiating effect.
