AI Technical Summary
Existing LED displays are prone to attracting dust during operation, leading to dust accumulation and blockage of heat dissipation devices. Furthermore, existing dust removal devices require shutdown for disassembly and cleaning, affecting ease of use.
An integrated dustproof and heat dissipation chassis for LED displays was designed, employing air-cooling and dust-filtering components, including an exhaust fan, air inlet pipe, air outlet pipe, air spray pipe, and dust-filtering components. After the air is filtered by the dust-filtering components, the hot air is exhausted by the air-cooling components. Combined with the rotating shaft and fan blades, the air is agitated and cooled. Continuous cleaning is achieved through a removable filter screen.
This technology enables dust removal and heat dissipation of LED displays without shutting down the system, improving lifespan and convenience, and ensuring continuous operation of the displays.

Description
Technical Field
[0001] This utility model relates to the technical field of LED displays, and in particular to an integrated dustproof and heat dissipation chassis for LED displays. Background Technology
[0002] When an LED display screen is in operation, a lot of heat is generated inside the cabinet. The back of the LED display screen easily attracts dust from the air, resulting in dust accumulation, which seriously affects the use of the LED display screen. At the same time, the heat dissipation device is also prone to attracting dust, causing blockage.
[0003] In the prior art, patent document CN218920843U discloses a dust removal and heat dissipation box for an LED display screen, comprising: an LED display screen, the LED display screen including a front and a back, and composed of multiple LED display modules spliced together; a display screen frame, the display screen frame being installed on the back of the LED display screen; and a box body, the box body being movably installed on the side of the display screen frame away from the LED display screen. Several sets of first and second heat dissipation windows are provided inside the box body, the first and second heat dissipation windows are arranged side by side, a cooling fan is provided on the first heat dissipation window, and a dust removal box is attached to the back of the first and second heat dissipation windows, the dust removal box containing a dust removal device.
[0004] During use, it was found that the above-mentioned device requires the entire equipment to be stopped and disassembled when cleaning the dust collection box, which is not very convenient. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides an integrated dustproof and heat dissipation chassis for LED displays.
[0006] This utility model discloses an integrated dustproof and heat dissipation enclosure for an LED display screen, comprising an LED display screen, an enclosure, a display screen frame, and an air outlet. The enclosure is provided with an air outlet, and the LED display screen is mounted on the front end of the enclosure via the display screen frame. It also includes a cooling component, which is installed on the enclosure and is used to cool the interior of the enclosure. During use, the display screen frame generates heat when operating, activating the cooling component. This allows the cooling component to expel the hot air inside the enclosure through the air outlet, improving cooling efficiency and extending service life.
[0007] Preferably, the air-cooled assembly includes an exhaust fan, an inlet pipe, an outlet pipe, a housing, a spray pipe, and a dust filter assembly. The exhaust fan is installed on the housing, with an inlet pipe at the input end and an outlet pipe at the output end. The outlet pipe extends to the inside of the housing and connects to the input end of the housing. Multiple spray pipes are installed on the housing, and a dust filter assembly is installed at the input end of the exhaust fan. When the exhaust fan is started, outside air is filtered by the dust filter assembly and enters the housing through the outlet pipe. The air entering the housing is blown into the housing through the multiple spray pipes, thereby exhausting the hot air inside the housing through the outlet.
[0008] Preferably, the dust filtration assembly includes a T-connector, an exhaust pipe, an internally threaded cap, a valve, and a first filter screen. The output end of the T-connector is connected to the input end of the exhaust fan. Each of the two sets of input ends of the T-connector is equipped with an exhaust pipe, and each set of exhaust pipes is equipped with a valve. Each set of exhaust pipe input ends is equipped with an external thread, and two sets of internally threaded caps are threadedly connected to the external thread. A first filter screen is installed on the internally threaded cap. Opening the first set of valves and closing the second set of valves allows the first filter screen on the first set of internally threaded caps to filter dust from the air. Switching between the two sets of valves allows the second set of first filter screens to filter dust from the air. The first set of internally threaded caps is disassembled, and the first set of first filter screens is cleaned of dust, thus ensuring the continuous operation of the LED display screen while cleaning is being performed.
[0009] Preferably, the assembly also includes a rotating shaft, a disc, and fan blades. The rotating shaft is rotatably mounted inside the housing, and a disc is mounted on the rotating shaft. Multiple sets of fan blades are arranged circumferentially on the outer wall of the disc, and multiple sets of air spray pipes are located below the rotating shaft. Outside air is exhausted through the multiple sets of air spray pipes, and the outside air blows the multiple sets of fan blades, thereby causing the fan blades to rotate rapidly inside the housing with the cooperation of the disc and the rotating shaft, thereby completing the air agitation inside the housing and achieving rapid cooling of the air inside the housing.
[0010] Preferably, it also includes a second filter screen, which is installed on the air outlet; the second filter screen prevents outside air from entering the housing through the air outlet, ensuring heat dissipation while improving dust resistance.
[0011] Preferably, it also includes protrusions, and multiple sets of protrusions are provided on the outer side wall of the internal thread cap; the operator can rotate the internal thread cap by means of the protrusions, which improves convenience.
[0012] Preferably, the first filter screen is made of stainless steel.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the display frame displays the screen, and the operation of the display frame generates heat, which activates the air-cooling component, thereby allowing the air-cooling component to exhaust the hot air inside the cabinet through the air outlet, improving the cooling effect and extending the service life.
