Abstract

The application provides an LED (Light Emitting Diode) display screen. The LED display screen provided by the application comprises a display screen box body, an air inlet pipe, an air outlet pipe and a circulating air path, wherein the air inlet pipe is arranged in the display screen box body and an air inlet fan is arranged at the air inlet of the air inlet pipe; the air outlet pipe is arranged in the display screen box body and an air outlet fan is arranged at the air outlet of the air outlet pipe; and the circulating air path is formed between the air inlet pipe and the air outlet pipe. By arranging the air inlet pipe and the air outlet pipe in the display screen box body and arranging the fans at the air outlets, the air flowing speed is accelerated, the distributed heat dissipation in the display screen box body is realized, the heat is not accumulated, the heat of the display screen is evenly dissipated and the heat dissipating efficiency is high.

Description

LED display

Technical field

The application relates to the LED display field, especially, relates to a kind of LED display.

Background technology

In prior art, LED display work produces amount of heat, at LED display upper end increase exhaust fan, the bottom is driven pore into and is carried out circulation cooling, but the LED display internal cavity is large, Air Flow is slow, dispel the heat inhomogeneous, and local parts are in the anxious thermal environment that produces in a short time amount of heat for a long time, have a strong impact on use safety and the serviceable life of LED display.

The utility model content

The application's purpose is to provide a kind of LED display, and large to solve the LED display internal cavity, Air Flow is slow, the inhomogeneous technical matters of dispelling the heat.

For achieving the above object, the application provides a kind of LED display, comprises display screen box body; Blast pipe is arranged in display screen box body, and the air inlet place of blast pipe is provided with air intake blower fan; Discharge pipe is arranged in display screen box body, and the air outlet place of discharge pipe is provided with air-out blower fan; Form circulation air path between blast pipe and discharge pipe.

Further, be provided with air vent on blast pipe and discharge pipe.

Further, blast pipe is connected by wind channel tube with discharge pipe.

Further, blast pipe is connected by one or more wind channel tubes with discharge pipe, and the two ends of wind channel tube are connected respectively on the air vent of blast pipe and discharge pipe.

Further, blast pipe is arranged on the middle part of display screen box body, and discharge pipe is arranged on the both sides of display screen box body.

Further, blast pipe and discharge pipe are separately positioned on display screen box body relative two ends.

Further, discharge pipe is many.

Further, blast pipe is many.

Further, the intake of blast pipe is less than the air output of discharge pipe.

Further, air intake blower fan and air-out blower fan are aerofoil fan.

The application has following beneficial effect:

By blast pipe and discharge pipe are set, and at airduct mouth place, blower fan is set in display screen box body, has accelerated wind speed and flowed, making the heat radiation that distributes in display screen box body, accumulated heat not, the display screen heat radiation evenly, radiating efficiency is high.

Except purpose described above, feature and advantage, the application also has other purpose, feature and advantage.The below is described in further detail the application with reference to figure.

Description of drawings

The accompanying drawing of formation the application's a part is used to provide the further understanding to the application, and the application's illustrative examples and explanation thereof are used for explaining the application, do not consist of the improper restriction to the application.In the accompanying drawings:

Fig. 1 is the cross-sectional schematic according to the application's LED display;

Fig. 2 is the blast pipe schematic diagram according to the application's LED display; And

Fig. 3 is the discharge pipe schematic diagram according to the application's LED display.

Embodiment

Embodiment to the application is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the application can be defined by the claims and cover is implemented.

Referring to Fig. 1, the LED display according to the application comprises: display screen box body 10; Blast pipe 20 is arranged in display screen box body 10, and the air inlet place of blast pipe 20 is provided with air intake blower fan; Discharge pipe 30 is arranged in display screen box body 10, and the air outlet place of discharge pipe 30 is provided with air-out blower fan; Form circulation air path between blast pipe 20 and discharge pipe 30.By blast pipe and discharge pipe are set, and at airduct mouth place, blower fan is set in display screen box body, has accelerated wind speed and flowed, making the heat radiation that distributes in display screen box body, accumulated heat not, the display screen heat radiation evenly, radiating efficiency is high.

Referring to Fig. 2 and Fig. 3, be provided with air vent 40 on blast pipe 20 and discharge pipe 30, form circulation air path by air vent 40, blast pipe 20 can be connected by wind channel tube with discharge pipe 30.Blast pipe 20 is connected by one or more wind channel tubes with discharge pipe 30, and the two ends of wind channel tube are connected respectively on the air vent 40 of blast pipe 20 and discharge pipe 30.

Referring to Fig. 1, according to the first embodiment of the application, blast pipe 20 is arranged on the middle part of display screen box body 10, and discharge pipe 30 is arranged on the two ends of display screen box body 10.

According to the second embodiment of the application, blast pipe 20 and discharge pipe 30 are separately positioned on two relative sides of display screen box body 10.

Discharge pipe 30 is many.Blast pipe 20 also can be many.The intake of blast pipe 20 is less than the air output of discharge pipe 30.Air intake blower fan and air-out blower fan are aerofoil fan.

As can be seen from the above description, the application's the above embodiments have realized following technique effect:

Extraneous cold air is sent blast pipe to by air intake blower fan, the road airduct (hole) of process blast pipe both sides is to two side flow, because the end of exhaust duct is installed the air draft axial flow blower, the running of exhaust blower makes in exhaust duct and produces negative pressure with the display screen inner chamber, cause circulation of air to be accelerated, heat in display screen is taken away rapidly, plays the effect of efficient, energy-conservation heat radiation; Display products electricity, luminous energy effect transform high, save cost; But System Implementation standardization, easily production and processing, simple installation is quick.
