[0023] Combine the following Figure 1 , the outdoor liquid crystal display screen capable of effectively controlling the temperature provided by the embodiment of the present application is described in detail through specific embodiments.

[0024] Please also read Figure 1 , Figure 1 It is a schematic diagram of the structure of an outdoor LCD screen capable of effectively controlling temperature provided by one embodiment of the present invention. An outdoor LCD screen 100 capable of effectively controlling temperature provided by one embodiment of the present invention comprises a housing 10, a light source assembly 11, a liquid crystal panel assembly 12, a diaphragm assembly 13, a heat exchange assembly 20 and a heat dissipation assembly 30. The light source assembly 11 is used to provide a light source for backlighting, the liquid crystal panel assembly 12 is used to provide an image, and the diaphragm assembly 13 is arranged between the liquid crystal panel assembly 12 and the light source assembly 11, so that the light source assembly 11, the liquid crystal panel assembly 12 and the diaphragm assembly 13 are arranged at intervals to form a first air duct 14 and a second air duct 15; the heat exchange assembly 20 is connected to the first air duct 14 and the second air duct 15; and the heat dissipation assembly 30 is attached to the heat exchange assembly 20 to transfer the heat in the heat exchange assembly 20 to the heat dissipation assembly 30.

[0025] Among them, the light source assembly 11 is used to provide backlight so that the image in the liquid crystal panel can be displayed. Common light sources include LEDs (light emitting diodes). The backlight can be uniform or a light source distributed in a certain way on the back of the liquid crystal screen. The diaphragm assembly 13 is an important part of the liquid crystal display screen 100, which is used to adjust the transmission and blocking of light. It can control the direction of light to ensure that only light that meets a specific direction can pass through the liquid crystal layer, thereby controlling the display of pixels. The liquid crystal panel assembly 12 is the core component of the liquid crystal display screen 100, which includes a liquid crystal layer and a series of electrodes. The arrangement state of the liquid crystal molecules is controlled by voltage. When the voltage changes, the arrangement state of the liquid crystal molecules also changes accordingly, thereby changing the degree of light transmission, controlling the brightness and color of each pixel, and finally realizing image display.

[0026] In this embodiment, the diaphragm assembly 13 forms a first air duct 14 and a second air duct 15 between the light source assembly 11 and the liquid crystal panel assembly 12. By providing a heat exchange assembly 20 connected to the first air duct 14 and the second air duct 15, and attaching the heat dissipation assembly 30 to the heat exchange assembly 20, heat can be effectively transferred and the heat dissipation effect can be optimized. This helps to reduce the impact of the heating of the display screen on the normal operation and life of the device.

[0027] Specifically, when the outdoor LCD screen 100 generates heat during operation, the outside air enters the housing 10, and the outside air can take the heat out of the housing 10 through the first air duct 14 between the diaphragm assembly 13 and the light source assembly 11 and the second air duct 15 between the diaphragm assembly 13 and the liquid crystal panel assembly 12, and the heat follows the air into the heat exchange assembly 20. The heat dissipation assembly 30 and the heat exchange assembly 20 are attached to each other, and at this time, the heat of the air in the heat exchange assembly 20 can be transferred to the heat dissipation assembly 30 by using water cooling or air cooling, thereby achieving the effect of cooling the LCD screen 100.

[0028] In some embodiments, a third air duct 16 is disposed on the housing 10 , one end of the third air duct 16 is connected to the first air duct 14 and the second air duct 15 , and the other end of the third air duct 16 is connected to the heat exchange component 20 .

[0029] By providing the third air duct 16 on the housing 10, the third air duct 16 is interconnected with the first air duct 14 and the second air duct 15. When the outside air enters the housing 10, it enters the first air duct 14 and the second air duct 15 respectively and takes out the heat. At this time, the air in the first air duct 14 and the second air duct 15 can enter the third air duct 16 together. Through such a setting, it is possible to prevent the air in the first air duct 14 and the second air duct 15 from staying in the housing 10, and the air circulation in the housing 10 can be promoted. In addition, by connecting the third air duct 16 and the heat exchange assembly 20, the air in the first air duct 14 and the second air duct 15 can all enter the heat exchange assembly 20, thereby improving the heat exchange efficiency.

[0030] In some embodiments, the heat exchange component 20 includes a heat exchange channel 21, the third air duct 16 is interconnected with the heat exchange channel 21, a fan component is provided at the connection between the heat exchange channel 21 and the third air duct 16, and the air outlet end of the fan component faces the heat exchange channel 21.

[0031] By connecting the third air duct 16 to the heat exchange channel 21, fresh air can be introduced into the heat exchange channel 21, increasing the air flow in the channel, thereby enhancing the heat exchange efficiency. The introduction of fresh air helps to prevent heat accumulation in the air in the heat exchange channel 21 and improve the heat exchange effect. The outlet end of the fan assembly facing the heat exchange channel 21 can provide additional wind force and increase the ventilation effect in the channel. This helps to strengthen the flow and circulation of air, thereby effectively controlling the temperature and humidity in the channel. Specifically, by facing the outlet end of the fan assembly toward the heat exchange channel 21, the air volume and wind speed can be accurately controlled, thereby achieving precise control of the heat exchange process. In this way, it can be adjusted according to actual needs to improve the controllability and adaptability of the system.

[0032] Wherein, the blower assembly can be a fan.

[0033] In some embodiments, the heat dissipation component 30 includes a heat dissipation channel 31 , the heat dissipation channel 31 and the heat exchange channel 21 are attached to each other, and circulating water is arranged in the heat dissipation channel 31 .

[0034] The fit between the heat dissipation channel 31 and the heat exchange channel 21 can effectively conduct heat and improve the heat dissipation efficiency. Through the flow of circulating water, the heat dissipation channel 31 can absorb the heat in the heat exchange channel 21 and take it away, thereby accelerating the heat dissipation and achieving more efficient heat dissipation. The flow of circulating water can help control the temperature stability in the heat dissipation channel 31. By adjusting the flow rate and temperature of the circulating water, the temperature in the heat dissipation channel 31 can be accurately controlled to prevent overheating or overcooling, thereby ensuring the normal operation and long-term stability of the system.

[0035] In some other embodiments, an air cavity is provided in the heat dissipation channel 31 for air cooling and heat dissipation. The heat dissipation channel 31 may be provided with air holes, and the ambient air outside may enter the heat dissipation channel 31 through the air holes. Since the temperature of the ambient air outside is lower than the temperature of the air in the heat exchange channel 21, when the ambient air circulates in the heat exchange channel 21, the temperature of the heat dissipation channel 21 is lower than the temperature of the heat exchange channel 31, so that the heat dissipation channel 21 and the heat exchange channel 31 can exchange heat, so that the temperature in the heat exchange channel 21 decreases. Through such a setting, the temperature of the liquid crystal display screen 100 can be controlled to prevent the liquid crystal display screen 100 from being too high when working outdoors.

[0036] In addition, the positions of the heat exchange channel 21 and the heat dissipation channel 31 can be arranged relative to each other, and the heat exchange channel 21 and the heat dissipation channel 31 only need to be close to each other for heat exchange. For example, when the heat exchange channel 21 is located close to the liquid crystal display screen 100, the heat dissipation channel 31 is located on one side of the heat exchange channel 21; when the heat dissipation channel 31 is located close to the liquid crystal display screen 100, the heat exchange channel 21 is located on one side of the heat dissipation channel 31.

[0037] In some embodiments, a plurality of ventilation holes are provided on the housing 10, and the ventilation holes are interconnected with the first air duct 14 and the second air duct 15. The provision of the ventilation holes can promote air flow and increase the ventilation effect. By being connected with the first and second air ducts 15, it can be ensured that air flows through the entire system, thereby effectively dissipating heat. And the ventilation holes can enhance the heat transfer process. Heat dissipated from the heat source component to the surrounding environment requires air flow to be taken away, and the provision of the ventilation holes can provide this necessary air flow path. By increasing the number and position of the ventilation holes, the heat dissipation efficiency of the entire system can be improved. Air flows through the ventilation holes, taking away heat, thereby reducing the system temperature and keeping it within a safe operating range.

[0038] In some embodiments, a temperature sensing probe is also included, and the temperature sensing probe is arranged at the air outlet and air inlet of the first air duct 14 and the second air duct 15. The temperature sensing probe can monitor the temperature of the air outlet and air inlet of the first and second air ducts 15 in real time. In this way, the temperature changes inside the system can be grasped in time, which helps to adjust the working state of the system in time to keep it within a safe temperature range. By monitoring the temperature of the air outlet and the air inlet, the heat dissipation effect can be evaluated. If the temperature is too high, it may mean insufficient heat dissipation or abnormal operation of the system. Measures can be taken in time to enhance the heat dissipation effect, such as increasing the wind speed or changing the number of vents.

[0039] It should be particularly noted that the outdoor LCD display screen 100 capable of effectively controlling the temperature provided by the embodiment of the utility model only shows the part related to the technical problem to be solved by the embodiment of the utility model. It can be understood that the outdoor LCD display screen 100 capable of effectively controlling the temperature provided by the embodiment of the utility model also includes other structures for realizing the functions of the outdoor LCD display screen 100 capable of effectively controlling the temperature, which will not be repeated one by one again.
