Description

Technical Field

[0001] The invention relates to the technical field of outdoor advertising screens, and in particular to a liquid cooling device for outdoor advertising screens. Background Art

[0002] Outdoor advertising display screens are electronic display devices installed in outdoor environments, mainly used to display advertisements, promotional information or other content. They usually use LED (light-emitting diode) technology, because LED screens have high brightness, wide viewing angle and long service life in outdoor environments, and can clearly display content even under direct sunlight. The main features of outdoor advertising display screens: High brightness: LED display screens have high brightness and can adapt to strong light environments to ensure clear communication of information. Waterproof and dustproof design: In order to adapt to harsh outdoor weather conditions, outdoor display screens usually have good waterproof and dustproof properties. Large size and high resolution: The screen is usually large in size, can be clearly seen from a long distance, and the resolution is relatively high. Energy saving: Modern LED technology enables outdoor advertising screens to provide high brightness while consuming less energy. Remote control and management: Outdoor advertising display screens can usually be remotely controlled through the network, which facilitates real-time updating and management of advertising content.

[0003] Common application scenarios include large squares, pedestrian streets and other crowded places for playing advertisements and city promotional videos. Mall exterior walls or surrounding areas for commercial advertising. Highways, subway stations, airports, etc. for advertising display and information release. Used for game score display, advertising playback, etc. These displays are usually used to attract the attention of a large number of people and enhance advertising effects through visual impact and dynamic content.

[0004] The heating problem of outdoor advertising display screens is a technical problem that requires special attention, especially when large size and high brightness are required, LED components will generate a lot of heat. If the heat is not handled properly, it will not only affect the service life of the display screen, but may also cause problems such as reduced brightness and poor picture quality. The following are several aspects related to the heating problem: LEDs generate heat when they emit light, especially high-brightness screens. The power supply part and driver chip of the display screen also generate additional heat when they work. Outdoor advertising displays are usually installed in open environments. In summer or hot weather, the external high temperature will also increase the heat dissipation needs of the equipment. When the temperature of the LED chip is too high, its luminous efficiency will decrease, resulting in a decrease in the brightness of the display screen. Overheating may cause LED color deviation and affect the visual effect of the advertisement. High temperature will accelerate the aging of LEDs and other electronic components and shorten the service life of the entire system. Long-term high temperature may cause the display screen components to burn out, and even cause safety problems such as fire. Outdoor LED displays are usually made of aluminum alloy materials or other materials with high thermal conductivity, which can help dissipate heat through their own structure. In addition, the internal design of the display screen will try to increase air flow and improve the heat dissipation effect.

[0005] High-power, high-brightness display screens are often equipped with fans or air circulation systems to accelerate air flow through mechanical means to reduce the temperature inside the display screen. However, existing cooling methods have the problems of high energy consumption, insufficient utilization of natural wind energy, and troublesome later maintenance.

[0006] In view of the above situation, in order to overcome the above technical problems, the present invention designs a liquid cooling device for outdoor advertising screens to solve the above technical problems. Summary of the invention

[0007] The technical purpose to be achieved by the present invention is to design a liquid cooling device for outdoor advertising screens, which uses lower energy consumption, utilizes natural wind energy for heat dissipation, and reduces the workload of subsequent maintenance.

[0008] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0009] A liquid cooling device for outdoor advertising screens includes a base, a mounting mechanism, a display screen, a heat dissipation mechanism, a fan and a cooling mechanism. The device is designed to solve the heat dissipation problem caused by high temperature when the outdoor advertising screen runs for a long time, especially in summer or other high temperature environments, to ensure that the screen can run stably for a long time and extend the service life of the device.

[0010] The installation mechanism of the device is located on the base and is the basic structural part of the entire device. The installation mechanism is not only used to fix the display screen and related heat dissipation equipment, but also has the function of collecting rainwater. When the cooling mechanism needs water for cooling, the installation mechanism collects rainwater for water replenishment. Such a design is very practical in outdoor environments because it can make full use of natural precipitation resources, thereby reducing the need for artificial water addition. The installation mechanism is also equipped with a pressurized water pump, which is responsible for circulating the collected water in the system to ensure the normal operation of the cooling mechanism, forming a closed-loop water cooling system, so that water resources can be used efficiently.

[0011] The display screen is installed on the side of the mounting mechanism. In order to ensure that the display screen is not affected by high temperature during long-term operation, the cooling system on the back is essential. The liquid cooling device combines liquid cooling with air cooling through a cooling mechanism that is closely integrated with the display screen, greatly improving the heat dissipation efficiency.

[0012] The heat dissipation mechanism is installed behind the mounting mechanism, and is specifically responsible for guiding the cold air to circulate through the vents and air channels, so that the coolant in the cooling mechanism can quickly dissipate heat. The excess heat is taken away by air flow, effectively reducing the internal temperature of the system and preventing the liquid cooling system from overheating. At the same time, the vent design of the heat dissipation mechanism fully considers the particularity of the outdoor environment, ensuring that no matter how high the outside temperature is, the internal system can maintain a good heat dissipation state.

[0013] In order to further improve the heat dissipation effect, the device is also equipped with multiple fans. When the ambient temperature is too high or the system load is too large, the fans can automatically start to assist the heat dissipation mechanism to accelerate the additional air flow. In this way, in hot weather, the fans can also effectively reduce the temperature and ensure the safe operation of the entire system.

[0014] The core part is the cooling mechanism, which is installed on the back of the display screen, close to the display screen. The cooling mechanism realizes large-area water circulation cooling through a special transition cavity design. The transition cavity allows the cooling water to flow over a larger surface area, increasing the contact area with the display screen, thereby removing heat more efficiently. This design can quickly transfer the heat from the back of the display screen to the cooling water, and then release the heat into the air through the heat dissipation mechanism, forming an efficient circulation cooling system. The dual heat dissipation mechanism of water cooling and air cooling ensures the stable operation of the display screen in high temperature and harsh environment. In particular, through rainwater collection and water circulation system, the maintenance cost and the need for manual intervention are further reduced, making this device very practical for long-term outdoor advertising, both environmentally friendly and efficient.

[0015] The installation mechanism includes a mounting plate, a circulating flow channel, a water storage tank, a water storage block, a control component, a water outlet channel and a pressurized water pump. The mounting plate is located above the base and is in the shape of a "U" character to ensure a stable structure and easy liquid circulation. The circulating flow channel is arranged inside the mounting plate to guide the flow of the coolant and form the core cooling passage of the system. The water storage tank is located at the top of the mounting plate and is used to store cooling water and provide a stable water supply. A water storage block is installed in the middle of the water storage tank.

[0016] The control component is installed in the circulation channel and is responsible for controlling the one-way flow of water to ensure the efficient operation of the entire liquid cooling system. To facilitate the circulation of the coolant, the water outlet channel is opened on the inner side of the circulation channel, through which the coolant can flow out of the circulation channel smoothly to complete the heat exchange. The booster water pump is installed below the circulation channel to provide the necessary water pressure to ensure that the water can circulate throughout the system. Through this design, the entire liquid cooling system forms an efficient and stable water circulation heat dissipation device.

[0017] The water storage block is set in a dome shape, and its design cleverly utilizes the shape characteristics to achieve efficient rainwater collection. The height of the water storage block gradually decreases from the middle to the surroundings, forming an inclined surface structure. This design can effectively guide rainwater to flow naturally to both sides, avoid excessive accumulation of water in the middle area, and thus improve the efficiency of rainwater collection.

[0018] When rain falls on the top of the water storage block, due to its dome-shaped structure, the water will flow around along the inclined surface and eventually enter the water storage tanks on both sides. This design not only makes full use of natural precipitation resources, but also reduces the pressure or potential damage to the equipment caused by rainwater accumulation. In addition, through the inclined structure of the water storage block, rainwater can enter the circulation system faster, avoiding evaporation losses caused by water retention, and further improving the working efficiency of the entire liquid cooling device.

[0019] The setting of this dome-shaped water storage block optimizes the rainwater collection process, making water resource utilization more efficient in outdoor environments, especially in the case of long-term unattended operation, ensuring the continuous heat dissipation capacity of the equipment.

[0020] There are two water outlet channels, one at the upper and lower ends of the circulation channel. This design ensures that the water circulation in the cooling mechanism can be carried out in the manner of "water inlet from below and water outlet from above". Through this flow mode, not only the efficiency of water circulation is effectively improved, but also the stability and sustainability of the cooling water flow are guaranteed. This up and down inlet and outlet water circulation design can ensure that the cooling water always flows on the optimal path, fully utilize the cooling capacity of the water, and avoid the accumulation or retention of hot water in the system. At the same time, such a design can also effectively extend the working time of the liquid cooling system, reduce maintenance requirements, and maintain the continuity and stability of the heat dissipation effect.

[0021] The control assembly includes multiple key components, namely a fixed ring, a control head, a fixed plate, a return spring and a control ball. The fixed ring is installed inside the circulation channel to fix and support the entire control assembly. A control head is installed below it, which is responsible for regulating the water flow so that the water can only enter the circulation channel through the outside world to ensure the stable operation of the cooling system. The fixed plate is located inside the fixed ring to provide stable support and fixation for the assembly to prevent the various components from being displaced under the impact of the water flow.

[0022] A return spring is installed below the fixed plate. The design of the return spring can ensure that the control component can automatically return to its initial position after the adjustment is completed. The control ball is connected to one end of the return spring, and its function is to control the one-way flow of water.

[0023] The heat dissipation mechanism is composed of a heat dissipation frame, an interception net and a drainage plate, which is designed to improve the cooling efficiency and the protection performance of the system. The heat dissipation frame is installed on the back of the mounting mechanism, providing a stable support structure for placing and fixing other heat dissipation components, while ensuring that cold air can flow smoothly to dissipate the heat generated when the display screen is working. The interception net is located on the side of the heat dissipation frame, mainly for protection, to prevent external dust, debris or insects from entering the heat dissipation system, keep the heat dissipation components clean, and avoid blocking the heat dissipation channel to ensure long-term stable operation of the system.

[0024] The guide plate is installed on the upper and lower surfaces of the heat sink and is tilted. Its design purpose is to change the direction of air flow and optimize the distribution of airflow, so that cold air flows through the heat dissipation components more effectively, while accelerating the discharge of hot air. The tilted guide plate can guide the cold air in and quickly take the hot air out, effectively improving the heat dissipation effect and preventing local overheating. This combined design ensures the efficient operation of the heat dissipation mechanism and extends the service life of the display.

[0025] The side of the heat sink is provided with ventilation holes, which are evenly distributed on both sides of the heat sink and are of the same number, maintaining a symmetrical design to ensure that the airflow can pass through the heat sink in a balanced manner to achieve a more efficient heat dissipation effect. The central axis of the ventilation holes is arranged to overlap, which further improves the efficiency of air circulation and helps to quickly discharge heat during the heat dissipation process.

[0026] Air channels are also opened in the upper and lower parts of the heat sink, which are adjacent to the guide plate and adopt an inclined design. The inclined air channel can guide the cold air into the heat dissipation system more quickly, while prompting the hot air to be discharged from the top, forming a good convection, thereby optimizing the entire heat dissipation process and improving the cooling capacity of the equipment.

[0027] The cooling mechanism consists of a cooling component, a surface groove and a cooling plate. The overall design is to improve the heat dissipation effect of the display screen and ensure that the temperature of the device can remain stable during long-term operation. The cooling component is installed on the back of the display screen, close to the display screen, and is used to directly absorb the heat generated when the display screen is working. It is the core part of the entire cooling system. In order to further improve the heat dissipation efficiency, the surface groove is opened on the back of the cooling component. The groove structure can increase the heat dissipation area, thereby increasing the heat dissipation speed.

[0028] The cooling plate is installed on the back of the cooling component as an additional heat dissipation layer. The cooling plate is used to further conduct and release heat into the air on the basis of heat dissipation in the surface grooves, forming a multi-level cooling effect. This design effectively improves the overall performance of the cooling mechanism and ensures reliable operation of the equipment in high temperature environments.

[0029] The surface groove is set in a semicircular shape, which can effectively increase the surface area in contact with the air, thereby improving the heat dissipation efficiency. The semicircular design makes the air flow smoother, promotes the discharge of hot air, and creates good conditions for the inflow of cold air. This structure can effectively reduce the retention of heat on the surface of the cooling component, ensuring that the heat can be quickly transferred to the external environment.

[0030] The upper part of the cooling plate is set in a wave shape, which further increases its surface contact area. The wave-shaped design can not only enhance the vortex effect of the airflow, making the air flow more active on the cooling plate and improving the efficiency of heat exchange, but also effectively break the stability of the airflow and promote the rapid discharge of hot air. This wave-shaped structure helps to improve the cooling effect, allowing the cooling water to more effectively remove heat, thereby ensuring the heat dissipation capacity of the display screen when working under high load and extending the service life of the equipment.

[0031] In summary, the combination of the semicircular surface grooves and the wavy cooling plate makes the cooling mechanism more superior in heat dissipation performance, ensuring the stable operation of the equipment under various environmental conditions.

[0032] The cooling component is composed of a water inlet, a cooling channel, a water outlet and a transition chamber, and is designed to optimize the cooling effect and improve the heat dissipation efficiency of the display screen. The water inlet is located at the lower part of one side of the cooling component and is specifically used to introduce cooling water. Through this water inlet, the cooling water enters the cooling component to provide the necessary water source for the subsequent cooling process.

[0033] The cooling channel is located inside the cooling component and adopts an S-shaped circulation structure design. This S-shaped structure not only effectively prolongs the flow path of water in the component, but also increases the contact time between the cooling water and the heat source during the flow process, ensuring the maximum cooling effect. When the cooling water flows in the channel, it absorbs the heat emitted by the display, thereby reducing the temperature of the display.

[0034] In addition, the transition chamber is opened between the cooling channels and is set at a fixed distance. This spacing design helps the cooling water to form a uniform flow rate when flowing, optimizes the distribution of the water flow, and reduces the formation of bubbles, ensuring the stability and effectiveness of the water flow. Overall, the design of this cooling component not only improves the cooling efficiency, but also ensures the stable operation of the system, allowing the display to maintain the best working condition in a high temperature environment.

[0035] The beneficial effects of the present invention are as follows:

[0036] 1. The present invention aims to effectively solve the problem of heat generated by the long-term operation of the display screen by setting a cooling mechanism behind the display screen. The core design of the cooling mechanism relies on a reciprocating cooling channel, combined with the setting of a transition chamber, to achieve a larger contact area, thereby obtaining a better cooling effect. The S-shaped circulation structure of the cooling channel not only effectively prolongs the flow path of the cooling water in the channel, but also enhances the contact time between the cooling water and the heat dissipated by the display screen, ensuring that the heat can be quickly and effectively taken away. The coordinated design of the cooling mechanism and the heat dissipation mechanism is also extremely important. The heat dissipation mechanism is responsible for further dissipating the heat absorbed by the cooling mechanism into the surrounding environment to ensure the overall heat dissipation efficiency of the system. The ventilation holes and guide plate design of the heat dissipation mechanism optimize the air flow, allowing cold air to enter in time, take away heat, and improve the cooling performance.

[0037] 2. In terms of resource conservation, the present invention adopts natural air cooling, which makes the cooling process not only efficient and environmentally friendly, but also reduces energy consumption. At the same time, a fan is installed, which can automatically start when the ambient temperature is too high, ensuring the normal operation of the display screen under high temperature conditions, thereby improving the reliability of the equipment. The auxiliary heat dissipation function of the fan enables the entire system to maintain a good heat dissipation state under extreme climatic conditions. The present invention is also provided with a water storage tank, which is specially used to collect rainwater for water resource replenishment. This design significantly reduces the subsequent maintenance workload, because the water storage tank can automatically collect water during natural rainfall, provide a continuous water supply, and ensure the normal operation of the cooling system without manual intervention. Through this comprehensive design, the present invention not only improves the heat dissipation effect of the display screen and extends the service life of the equipment, but also improves the sustainability and environmental protection of the system.

DETAILED DESCRIPTION

[0050] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0051] like Figure 1-9As shown, a liquid cooling device for an outdoor advertising screen includes a base 1, a mounting mechanism 2, a display screen 3, a heat dissipation mechanism 4, a fan 5 and a cooling mechanism 6. The device is designed to solve the heat dissipation problem caused by high temperature when the outdoor advertising display screen 3 is running for a long time, especially in summer or other high temperature environments, to ensure that the display screen 3 can operate stably for a long time and extend the service life of the device.

[0052] The mounting mechanism 2 of the device is located on the base 1 and is the basic structural part of the entire device. The mounting mechanism 2 is not only used to fix the display screen 3 and related heat dissipation equipment, but also has the function of collecting rainwater. When the cooling mechanism 6 needs water for cooling, the mounting mechanism 2 collects rainwater for water replenishment. Such a design is very practical in outdoor environments because it can make full use of natural precipitation resources, thereby reducing the need for artificial water addition. The mounting mechanism 2 is also equipped with a pressurized water pump 27, which is responsible for circulating the collected water in the system to ensure the normal operation of the cooling mechanism 6, forming a closed-loop water cooling system, so that water resources can be used efficiently.

[0053] The display screen 3 is mounted on the side of the mounting mechanism 2. In order to ensure that the display screen 3 is not affected by high temperature during long-term operation, the cooling system on the back is essential. The liquid cooling device combines liquid cooling with air cooling through the cooling mechanism 6 that is closely combined with the display screen 3, greatly improving the heat dissipation efficiency.

[0054] The heat dissipation mechanism 4 is installed behind the mounting mechanism 2, and is specifically responsible for guiding the cold air to circulate through the vents and air flow channel 412, so that the coolant of the cooling mechanism 6 can quickly dissipate heat. The excess heat is taken away by the air flow, which effectively reduces the internal temperature of the system and prevents the liquid cooling system from overheating. At the same time, the vent design of the heat dissipation mechanism 4 fully considers the particularity of the outdoor environment, ensuring that no matter how high the external temperature is, the internal system can maintain a good heat dissipation state.

[0055] In order to further improve the heat dissipation effect, the device is also provided with a plurality of fans 5. When the ambient temperature is too high or the system load is too large, the fans 5 can be automatically started to assist the heat dissipation mechanism 4 to perform additional air flow acceleration. In this way, in hot weather, the fans 5 can also effectively reduce the temperature and ensure the safe operation of the entire system.

[0056] The core part is the cooling mechanism 6, which is installed on the back of the display screen 3 and is close to the display screen 3. The cooling mechanism 6 realizes large-area water circulation cooling through a special transition chamber 614 design. The transition chamber 614 allows the cooling water to flow over a larger surface area, increasing the contact area with the display screen 3, thereby taking away the heat more efficiently. This design can quickly transfer the heat on the back of the display screen 3 to the cooling water, and then release the heat into the air through the heat dissipation mechanism 4, forming an efficient circulating cooling system. The dual heat dissipation mechanism of water cooling and air cooling ensures the stable operation of the display screen 3 in high temperature and harsh environment. In particular, through rainwater collection and water circulation system, the maintenance cost and the need for manual intervention are further reduced, making this device very practical in long-term outdoor advertising broadcasting, both environmentally friendly and efficient.

[0057] like Figure 3 As shown, the mounting mechanism 2 includes a mounting plate 21, a circulating flow channel 22, a water storage tank 23, a water storage block 24, a control component 25, a water outlet channel 26 and a pressurized water pump 27. The mounting plate 21 is located above the base 1, and its shape is a "U" shape, which ensures that the structure is stable and easy for liquid circulation. The circulating flow channel 22 is arranged inside the mounting plate 21 to guide the flow of the coolant and form the core cooling passage of the system. The water storage tank 23 is located at the top of the mounting plate 21, and is used to store cooling water and provide a stable water supply. A water storage block 24 is installed in the middle of the water storage tank 23.

[0058] The control component 25 is installed in the circulation channel 22 and is responsible for controlling the unidirectional flow of water to ensure the efficient operation of the entire liquid cooling system. To facilitate the circulation of the coolant, the water outlet channel 26 is opened on the inner side of the circulation channel 22, through which the coolant can smoothly flow out of the circulation channel 22 to complete the heat exchange. The booster water pump 27 is installed below the circulation channel 22 to provide the necessary water pressure to ensure that the water can circulate in the entire system. Through this design, the entire liquid cooling system forms an efficient and stable water circulation heat dissipation device.

[0059] The water storage block 24 is set in a dome shape, and its design cleverly utilizes the shape characteristics to achieve efficient rainwater collection. The height of the water storage block 24 gradually decreases from the middle to the surroundings, forming an inclined surface structure. This design can effectively guide rainwater to flow naturally to both sides, avoid excessive accumulation of water in the middle area, and thus improve the rainwater collection efficiency.

[0060] When rain falls on the top of the water storage block 24, due to its dome-shaped structure, the water will flow around along the inclined surface and eventually enter the water storage tanks 23 on both sides. This design can not only make full use of natural precipitation resources, but also reduce the pressure or potential damage to the equipment caused by rainwater accumulation. In addition, through the inclined structure of the water storage block 24, rainwater can enter the circulation system faster, avoiding evaporation loss caused by water retention, and further improving the working efficiency of the entire liquid cooling device.

[0061] The arrangement of the dome-shaped water storage block 24 optimizes the rainwater collection process, making the use of water resources in outdoor environments more efficient, especially in the case of long-term unattended operation, thereby ensuring the continuous heat dissipation capacity of the equipment.

[0062] There are two water outlet channels, one at the upper and lower ends of the circulation channel 22. This design ensures that the water circulation in the cooling mechanism 6 can be carried out in the manner of "water inlet from below and water outlet from above". Through this flow mode, not only the efficiency of the water circulation is effectively improved, but also the stability and sustainability of the cooling water flow are guaranteed. This water circulation design with water inlet and outlet from above can ensure that the cooling water always flows on the optimal path, fully utilizes the cooling capacity of the water, and avoids the accumulation or retention of hot water in the system. At the same time, such a design can also effectively extend the working time of the liquid cooling system, reduce maintenance requirements, and maintain the continuity and stability of the heat dissipation effect.

[0063] like Figure 4 As shown, the control assembly 25 includes a plurality of key components, namely, a fixing ring 251, a control head 252, a fixing plate 253, a return spring 254 and a control ball 255. The fixing ring 251 is installed inside the circulation channel 22 to fix and support the entire control assembly 25. A control head 252 is installed below it, which is responsible for regulating the flow of water so that the water can only enter the circulation channel 22 through the outside to ensure the stable operation of the cooling system. The fixing plate 253 is located inside the fixing ring 251 to provide stable support and fixation for the assembly to prevent the displacement of various components under the impact of the water flow.

[0064] A return spring 254 is installed below the fixed plate 253. The design of the return spring 254 can ensure that the control component 25 can automatically return to the initial position after the adjustment is completed. The control ball 255 is connected to one end of the return spring 254, and its function is to control the unidirectional flow of water.

[0065] like Figure 5As shown, the heat dissipation mechanism 4 is composed of a heat dissipation frame 41, an interception net 42 and a guide plate 43, which is intended to improve the cooling efficiency and the protection performance of the system. The heat dissipation frame 41 is installed on the back of the mounting mechanism 2 to provide a stable support structure for placing and fixing other heat dissipation components, while ensuring that cold air can flow smoothly to dissipate the heat generated by the display screen 3 when it is working. The interception net 42 is located on the side of the heat dissipation frame 41, mainly for protection, to prevent external dust, debris or insects from entering the heat dissipation system, to keep the heat dissipation components clean, and to avoid blocking the heat dissipation channel to ensure long-term stable operation of the system.

[0066] The guide plate 43 is installed on the upper and lower surfaces of the heat sink 41 and is in an inclined state. Its design purpose is to optimize the distribution of airflow by changing the direction of air flow, so that cold air flows through the heat sink more effectively, while accelerating the discharge of hot air. The inclined guide plate 43 can guide the cold air to enter and quickly take the hot air out, effectively improving the heat dissipation effect and preventing the local temperature from being too high. This combined design ensures the efficient operation of the heat dissipation mechanism 4 and extends the service life of the display screen 3.

[0067] like Figure 6 As shown, ventilation holes 411 are provided on the side of the heat sink 41. These ventilation holes 411 are evenly distributed on both sides of the heat sink 41, and the number is the same, maintaining a symmetrical design, ensuring that the airflow can pass through the heat sink 41 in a balanced manner, achieving a more efficient heat dissipation effect. The central axis of the ventilation holes 411 is arranged to overlap, further improving the efficiency of air circulation, which helps to quickly discharge heat during the heat dissipation process.

[0068] The upper and lower parts of the heat sink are also provided with air channels 412, which are adjacent to the guide plate 43 and are inclined. The inclined air channels 412 can guide the cold air to enter the heat dissipation system more quickly, while causing the hot air to be discharged from the top to form a good convection, thereby optimizing the entire heat dissipation process and improving the cooling capacity of the device.

[0069] like Figure 7 As shown, the cooling mechanism 6 is composed of a cooling component 61, a surface groove 62 and a cooling plate 63. The overall design is intended to improve the heat dissipation effect of the display screen 3 and ensure that the temperature of the device can remain stable during long-term operation. The cooling component 61 is installed on the back of the display screen 3, close to the display screen 3, and is used to directly absorb the heat generated by the display screen 3 when it is working. It is the core part of the entire cooling system. In order to further improve the heat dissipation efficiency, the surface groove 62 is opened on the back of the cooling component 61. The groove structure can increase the heat dissipation area, thereby increasing the heat dissipation speed.

[0070] The cooling plate 63 is installed on the back of the cooling assembly 61 as an additional heat dissipation layer. The cooling plate 63 is used to further conduct and release the heat into the air on the basis of the heat dissipation of the surface groove 62, thus forming a multi-level cooling effect. This design effectively improves the overall performance of the cooling mechanism 6 and ensures the reliable operation of the equipment in a high temperature environment.

[0071] The surface groove 62 is set in a semicircular shape, which can effectively increase the surface area in contact with the air, thereby improving the heat dissipation efficiency. The semicircular design makes the air flow smoother, promotes the discharge of hot air, and creates good conditions for the inflow of cold air. This structure can effectively reduce the retention of heat on the surface of the cooling component 61, ensuring that the heat can be quickly transferred to the external environment.

[0072] The upper part of the cooling plate 63 is arranged in a wave shape, which further increases its surface contact area. The wave-shaped design can not only enhance the vortex effect of the airflow, making the air more active when flowing on the cooling plate 63, improving the efficiency of heat exchange, but also effectively break the stability of the airflow and promote the rapid discharge of hot air. This wave-shaped structure helps to improve the cooling effect, allowing the cooling water to more effectively take away the heat, thereby ensuring the heat dissipation capacity of the display screen 3 when working under high load and extending the service life of the device.

[0073] In summary, the combination of the semicircular surface groove 62 and the wavy cooling plate 63 makes the cooling mechanism 6 more superior in heat dissipation performance, ensuring stable operation of the equipment under various environmental conditions.

[0074] like Figure 8 As shown, the cooling component 61 is composed of a water inlet 611, a cooling channel 612, a water outlet 613 and a transition chamber 614, and is designed to optimize the cooling effect and improve the heat dissipation efficiency of the display screen 3. The water inlet 611 is located at the lower part of one side of the cooling component 61 and is specifically used to introduce cooling water. Through this water inlet 611, the cooling water enters the cooling component 61 to provide the necessary water source for the subsequent cooling process.

[0075] The cooling channel 612 is provided inside the cooling component 61 and is designed with an S-shaped circulation structure. This S-shaped structure not only effectively prolongs the flow path of the water flow in the component, but also increases the contact time between the cooling water and the heat source during the flow process, thereby ensuring the maximum cooling effect. When the cooling water flows in the channel, it absorbs the heat emitted by the display screen 3, thereby reducing the temperature of the display screen 3.

[0076] In addition, the transition chamber 614 is opened between the cooling channels 612 and is arranged at a fixed distance. This spacing design helps the cooling water to form a uniform flow rate when flowing, optimizes the distribution of the water flow, and reduces the formation of bubbles, ensuring the stability and effectiveness of the water flow. Overall, the design of this cooling component 61 not only improves the cooling efficiency, but also ensures the stable operation of the system, so that the display screen 3 can maintain the best working state in a high temperature environment.

[0077] During the working process of the present invention, when it rains, rainwater will drip onto the water storage block 24, and slide down the water storage block 24 into the two sides of the water storage tank 23, and then enter the circulation channel 22. When the water pressure in the circulation channel 22 is insufficient, the water enters the water outlet channel 26 through the control component 25 to realize the water replenishment of the cooling mechanism 6; the pressurized water pump 27 drives the water inside the circulation channel 22 to flow, and the flow direction is from the high water outlet channel 26 to the low water outlet channel 26;

[0078] Under the action of the pressurized water pump 27, water flows in from the lower water inlet 611, circulates in the cooling channel 612, and flows out from the water outlet 613, thereby achieving continuous cooling of the display screen 3; the surface groove 62 and the cooling plate 63 quickly take away the heat of the cooling component 61 with the help of the heat dissipation mechanism 4, thereby achieving cooling;

[0079] When the outdoor temperature is not high, the load of the display screen 3 is small, and the heat dissipation demand of the cooling mechanism 6 can be met through the ventilation holes 411 and the air flow channel 412. When the temperature is high in summer, the fan 5 is started to speed up the air flow, thereby ensuring the cooling efficiency of the heat dissipation mechanism 4, thereby ensuring the stable operation of the display screen 3.
