Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular discloses a heat dissipation duct structure for a display screen. Background Technology

[0002] Micro LED is an ultra-thin LED display widely used in the commercial display industry. With the rapid development of display technology, the market has placed higher demands on the thickness and brightness of displays, especially outdoor LED displays. To avoid the impact of outdoor light on the display effect, the power density of the core components (such as LED chips, driver ICs, and power modules) inside outdoor LED displays has increased accordingly. This has led to a sharp increase in the heat generated by these components. Coupled with their ultra-thin design, conventional heat dissipation equipment is difficult to adapt, making it difficult to dissipate internal heat quickly. This results in temperature accumulation inside the display unit, causing a series of problems such as color distortion, brightness decay, and shortened component lifespan. In severe cases, it can even cause permanent hardware damage. Utility Model Content

The housing has an air inlet 5 and an air outlet 6, which are respectively connected to the cavity. The first fan 4 discharges air from the cavity through the air outlet 6 to dissipate heat from the display screen unit 3. The rotating first fan 4 creates a negative pressure state inside the cavity, drawing outside air into the cavity through the air inlet 5.

[0020] Specifically, the housing component includes a front frame 1 and a rear shell 2; the rear shell 2 and the front frame 1 enclose a cavity, and the display unit 3 is mounted on the front frame 1, with one side of the display unit 3 located in the front frame 1 and the other side of the display unit 3 facing the cavity.

After the hot air in the accommodating cavity flows out through the air outlet 6, a negative pressure is formed in the accommodating cavity, and outside air flows in naturally through the air inlet 5. This design saves on the need for an active air intake device and makes more efficient use of the internal space of the display screen.

[0023] Specifically, the first fan 4 is located above the air inlet 5, and the air inlet 5 is located below the air outlet 6.

The three adjacent first fans 4 are arranged from the top of the accommodating cavity toward the air outlet 6, and an air duct is formed between the three adjacent first fans 4 to transport the hot air from the top of the accommodating cavity to the air outlet 6.

[0028] Specifically, the first fan 4 is a centrifugal fan, which has a volute and an impeller; one end of the volute is connected to the accommodating cavity, and the other end is connected to the air outlet 6. The rotation of the impeller gathers the hot air in the accommodating cavity to the air outlet 6 through the volute.

[0030] Specifically, the housing component is provided with a detachable protective net 7, which is used to cover the air inlet 5 and the air outlet 6.

[0031] In actual use, the protective mesh 7 of the air inlet 5 also has a detachable filter element, which is used to filter dust in the outside air.

[0032] Specifically, the accommodating cavity also has a second fan 8, which is a axial fan. The second fan 8 is arranged parallel to the display unit 3, and the center line of the axis of the second fan 8 is perpendicular to the display unit 3.

[0033] Preferably, the second fan 8 is located between the two rows of first fans 4.

[0034] Specifically, there are multiple second fans 8, which are spaced apart in the accommodating cavity.
