[0032] The cooling assembly 2 comprises a cooling plate 21, a plurality of heat-conducting pins 22 are equidistantly arranged on an end surface of the cooling plate 21 close to the touch screen assembly 1, the heat-conducting pins 22 are provided with heat dissipation portions 23 protruding from the touch screen assembly 1, and heat-conducting sheets 24 are connected between the heat-conducting pins 22, one end of the heat-conducting sheet 24 away from the cooling plate 21 is connected to the touch screen assembly 1;

[0035] The end surface of the cooling plate 21 close to the touch screen assembly 1 is equidistantly provided with a plurality of heat-conducting pins 22, the heat dissipation portions 23 of the heat-conducting pins 22 protrude from the cooling plate 21 to form a plurality of contact points, which can quickly absorb the heat generated by the touch screen assembly 1. The heat-conducting sheets 24 are connected between the heat-conducting pins 22, which effectively bridge the heat-conducting pins 22 and the touch screen assembly 1, ensuring that the heat can be quickly transmitted to the cooling plate 21 through the heat-conducting sheets 24.

[0036] On the side of the cooling portion facing the touch screen assembly 1, a heat dissipation pipe 3 surrounding the periphery of the touch screen assembly 1 is connected. The heat dissipation pipe 3 is filled with cooling liquid, which circulates through the pipe under the push of a micro pump 4. The micro pump 4 dynamically adjusts the flow rate of the cooling liquid according to the temperature change of the touch screen to adapt to the heat dissipation demand in the working state.

[0037] In summary, by arranging a plurality of heat-conducting pins 22 between the touch screen assembly 1 and the cooling plate 21 and connecting heat-conducting sheets 24 between the heat-conducting pins 22, efficient heat conduction of the heat generated by the touch screen is realized, the heat-conducting pins 22 and the heat-conducting sheets 24 expand the heat conduction path, so that the heat of the touch screen can be quickly conducted to the cooling plate 21, the heat dissipation portions 23 protruding from the touch screen assembly 1 are arranged on the heat-conducting pins 22, so that the heat dissipation pipe 3 can be connected to the heat-conducting pins 22 for heat conduction and can also cover the periphery of the touch screen assembly 1 to further play a cooling effect, the cooling liquid in the heat dissipation pipe 3 is driven to circulate by the micro pump 4, thereby realizing active heat dissipation and effectively reducing the heat generated by the touch screen assembly 1 in high-load operation.

[0038] In an embodiment, the cooling plate 21 is further provided with a heat-conducting block 25 adjacent to one end surface of the touch screen assembly 1.

One end surface of the heat-conducting block 25 is connected to the touch screen assembly 1, and one side of the heat-conducting block 25 is connected to the heat-conducting pin 22. The heat-conducting block 25 further enhances the heat conduction efficiency between the touch screen assembly 1 and the cooling plate 21.

One end surface of the heat-conducting block 25 is connected to the touch screen assembly 1, and one side of the heat-conducting block 25 is connected to the heat-conducting pin 22. The heat-conducting block 25 further enhances the heat conduction efficiency between the touch screen assembly 1 and the cooling plate 21.

The combination of the heat-conducting pin 22 and the heat-conducting block 25 forms an efficient heat conduction path.

[0040] In an embodiment, the outer side of the heat dissipation pipe 3 is flush with the outer side of the cooling plate 21 and the circuit board 5, and the outer side of the heat dissipation pipe 3 is surrounded by an outer shell 6, which covers the cooling plate 21 and the circuit board 5. The surrounding coverage of the outer shell 6 not only protects the cooling plate 21 and the circuit board 5 from the external environment, but also further enhances the heat dissipation effect. The material of the outer shell 6 is usually a metal material with good heat conduction performance, such as aluminum alloy or copper alloy, to ensure that heat can be effectively conducted from the cooling plate 21 and the circuit board 5 to the outer shell 6, and dissipated to the environment through the surface of the outer shell 6.

[0041] In an embodiment, the inner side of the shell 6 is provided with a plurality of mounting grooves corresponding to the heat dissipation pipes 3, and semiconductor refrigeration plates are mounted in the mounting grooves, with the refrigeration surface and the heat dissipation surface of the semiconductor refrigeration plates being connected to the heat dissipation pipes 3 and the shell 6, respectively. By using semiconductor refrigeration plates, the heat dissipation efficiency of the touch screen assembly 1 can be further improved. When the semiconductor refrigeration plates are in operation, the refrigeration surface absorbs heat, which is transferred from the cooling plate 21 to the heat dissipation surface through the Peltier effect, and then dissipated to the environment through the heat dissipation surface, the heat dissipation pipes 3, and the shell 6. This refrigeration method has the advantages of fast response speed and accurate control, and can effectively cope with the heat generated by the touch screen assembly 1 during long-time operation or high-load operation.

[0042] In order to further optimize the heat dissipation effect, the outer side of the shell 6 can also be provided with heat dissipation fins. The heat dissipation fins can increase the surface area of the shell 6 in contact with air, thereby improving the heat dissipation efficiency. In actual applications, the shape, size, and distribution of the heat dissipation fins can be designed according to specific requirements to achieve the best heat dissipation effect.

[0043] In an embodiment, the touch screen assembly 1 includes a protective layer 101, a touch control layer 102, and a display layer 103 stacked in sequence, and the display layer 103 is connected to the heat conduction sheet 24. In order to improve the durability and reliability of the touch screen assembly 1, the protective layer 101 can be made of scratch-resistant and impact-resistant materials such as tempered glass or high-strength plastic. In addition, the touch control layer 102 can use capacitive touch control technology to provide more sensitive and accurate touch control response.

[0044] Reference Figure 5 In an embodiment, the cooling plate 21 is provided with a plurality of heat-conducting silicone columns 27 at one end facing the circuit board 5, and the heat-conducting silicone columns 27 are connected to the heat-generating elements of the circuit board 5. The heat-conducting silicone columns 27 directly transfer the heat generated by the heat-generating elements to the cooling plate 21, thereby achieving efficient heat conduction. The heat-conducting silicone columns 27 have good flexibility and heat conduction performance, and can adapt to the shapes and sizes of different heat-generating elements, ensuring the uniformity and reliability of heat transfer. In addition, the use of heat-conducting silicone columns 27 can also reduce the contact thermal resistance between the heat-generating elements and the cooling plate 21, further improving the heat dissipation efficiency.

[0045] In an embodiment, four micro fans 7 are arranged between the circuit board 5 and the cooling plate 21, and the four micro fans 7 are respectively distributed at the four corners of the cooling plate 21. The arrangement of the micro fans 7 can further enhance the heat dissipation effect. The four micro fans 7 are evenly distributed at the four corners of the cooling plate 21, and the air outlets of the four micro fans 7 respectively face different directions, so that the vortex is formed between the circuit board 5 and the cooling plate 21, ensuring the uniformity and comprehensiveness of air flow. When the micro fans 7 work, cold air is sucked in and hot air is pushed out from the other side of the cooling plate 21, forming effective air convection, thereby accelerating the heat dissipation of the surface of the cooling plate 21. In addition, the use of the micro fans 7 can also reduce the surface temperature of the cooling plate 21, further improving the stability and service life of the touch screen assembly 1.

[0046] In an embodiment, a plurality of heat dissipation holes 61 are arranged on opposite sides of the shell 6, and the heat dissipation holes 61 are arranged between the circuit board 5 and the cooling plate 21. Through the design of the heat dissipation holes 61, the heat generated inside can be effectively discharged, avoiding the accumulation of heat inside the device. The heat dissipation holes 61 not only help to improve the heat dissipation efficiency, but also maintain the air circulation inside the device, thereby reducing the overall temperature. In actual application, the size, shape and number of the heat dissipation holes 61 can be adjusted according to specific needs to achieve the best heat dissipation effect.

[0047] In an embodiment, a temperature sensor is arranged at one end of the touch screen assembly 1 close to the cooling plate 21, and the temperature sensor is electrically connected with the micro fans 7 and the micro pump 4 respectively.

[0048] Through real-time monitoring of the temperature sensor, the system can accurately grasp the temperature change of the touch screen assembly 1. When the temperature sensor detects that the temperature exceeds the preset threshold, it will send a signal to the micro fans 7 and the micro pump 4 to start or adjust their working state. The micro fans 7 will correspondingly increase the speed to improve the air flow rate, thereby enhancing the heat dissipation effect. At the same time, the micro pump 4 will also adjust the working state as needed to ensure that the circulation of the cooling liquid in the cooling plate 21 is more efficient.
