[0019] like Figure 1-4As shown, this utility model discloses a liquid crystal display device with a heat dissipation channel structure, including a display device housing 1 and a cooling fan module 2. The display device housing 1 houses a liquid crystal screen body 3, a front airflow guide component, and a rear airflow guide component 6. The front and rear airflow guide components 6 are respectively located at the front and rear ends of the liquid crystal screen body 3. The front airflow guide component forms a front airflow channel 102 with the inner wall of the display device housing 1, and the rear airflow guide component 6 forms a rear airflow channel 103 with the inner wall of the display device housing 1. The rear end of the display device housing 1 is provided with a cooling fan module 2. The air inlet 131 is connected to the rear air duct 103. One side of the LCD screen body 3 and the inner wall of the display device housing 1 form a guide air vent 101. The front air duct 102 and the rear air duct 103 are connected through the guide air vent 101. The display device housing 1 has a heat dissipation air outlet 132 at the corresponding position of the end of the air inlet 131 away from the guide air vent 101. The air inlet 131, the rear air duct 103, the front air duct 102 and the heat dissipation air outlet 132 form a heat dissipation air duct. The cooling fan module 2 can cooperate with the heat dissipation air duct to dissipate heat on the surface of the LCD screen body 3.

[0020] By combining the cooling fan module 2 with the cooling duct, the heat generated by the LCD screen body 3 can be efficiently removed, avoiding the shortened lifespan of the LCD screen body 3 due to prolonged outdoor use. This meets the outdoor usage needs of users and enhances the competitiveness of the product.

[0021] When used outdoors, the cooling fan module 2 is activated. The external airflow flows through the air inlet 131, the rear air duct 103, the front air duct 102 and the heat dissipation outlet 132, so that the airflow flows around the surface channel of the LCD screen body 3, effectively removing the temperature of the LCD screen body 3 and cooling the LCD screen body 3, avoiding prolonged temperature rise and affecting the product's service life.

[0022] The display device housing 1 includes a front display frame 11, a touch screen body 12, and a rear display housing 13, with the touch screen body 12 fixedly mounted on the front display frame 11.

[0023] The touch screen body 12 enables the device to have touch operation functionality, and the heat dissipation duct is set between the LCD screen body 3 and the touch screen body 12.

[0024] The LCD display device with a heat dissipation channel structure also includes a controller 7. The rear housing 13 of the display is provided with wiring holes 133 that cooperate with the controller 7. The controller 7 is provided with multiple expansion interfaces 71.

[0025] By expanding the settings of interface 71, the flexibility of device use can be improved.

[0026] There are two front air duct guides, namely the first front air duct guide 4 and the second front air duct guide 5. The first front air duct guide 4 and the second front air duct guide 5 are respectively arranged on both sides of the front air duct 102. The front and rear ends of the front air duct 102 are respectively matched with the air duct 101 and the heat dissipation air outlet 132.

[0027] With the first front air duct guide 4 and the second front air duct guide 5 respectively set on both sides of the front air duct 102, the airflow can be effectively guided, so that the airflow flows from the guide air outlet 101 to the heat dissipation air outlet 132.

[0028] The rear air duct guide 6 is located on the side of the air inlet 131 away from the air guide vent 101, and the rear air duct guide 6 can guide the airflow to the air guide vent 101.

[0029] By setting up the airflow guide, the airflow that flows towards the heat dissipation vent 132 is prevented from flowing upward from between the inner wall of the display device housing 1 and the side of the LCD screen body 3 to the rear end of the LCD screen body 3, thus affecting the heat dissipation of the LCD screen body 3.

[0030] The LCD screen display device with heat dissipation channel structure also includes an air duct blocking component 8. The air duct blocking component 8 is located at the rear end of the LCD screen body 3 and is located on the side of the LCD screen body 3 away from the rear air duct guide component 6. The air duct blocking component 8 can prevent the airflow flowing towards the heat dissipation outlet 132 from flowing back into the display device housing 1.

[0031] The rear air duct guide 6, the front air duct guide, and the air duct obstruction 8 are all made of foam, which reduces the difficulty and cost of processing.

[0032] The cooling fan module 2 includes a fan module housing 21 and multiple cooling fans 22. The fan module housing 21 is provided with air inlet holes 211 that cooperate with the cooling fans 22. The multiple cooling fans 22 are equally spaced inside the fan module housing 21.

[0033] The combined action of multiple cooling fans 22 can accelerate the airflow speed in the cooling duct and improve the heat dissipation capacity.

[0034] As can be seen from the above, the beneficial effects of this utility model are: by adopting its mechanism, it can effectively solve the problem of insufficient heat dissipation leading to damage to the LCD screen when the display device is used in an outdoor environment. Through the cooperation of the cooling fan module 2 and the heat dissipation duct, the heat generated by the LCD screen body 3 can be efficiently removed, avoiding the situation that the lifespan of the LCD screen body 3 is shortened due to long-term outdoor use. It can meet the outdoor use needs of users and improve the competitiveness of the product.

[0035] The specific embodiments described above are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
