Axial flow fans and filter elements are installed on the inner walls of the ventilators 18 from the inside to the outside. Two air-cooling chambers 4 are respectively arranged at the upper and lower ends of the water-cooling cavity 5, and ventilators 18 are installed at the positions corresponding to the air-cooling chambers 4 and on the back of the heat dissipation housing 3. The axial flow fan in the ventilator 18 can quickly introduce the external cold air into the air-cooling chamber 4, and the filter element can effectively filter the dust and impurities in the air to prevent them from entering the heat dissipation device to affect the heat dissipation effect or damage the components; When the smart screen is working, the outside cold air enters the air-cooling chamber 4 through the ventilator 18, and works with the heat dissipation mechanism to take away the heat, thereby achieving efficient air-cooling and heat dissipation, solving the problem that the existing smart screen heat dissipation device has poor air cooling effect and is easily affected by dust. Compared with the existing technology, the heat dissipation efficiency is improved and the service life of the device is extended; A drive module and two symmetrically arranged cooling plates 6 are installed in the heat dissipation housing 3.

The cooling surfaces of the two cooling plates 6 fit with the heat-conducting metal belt 7. The heat dissipation surfaces of the two cooling plates 6 extend to the inside of the water-cooling cavity 5. The refrigeration plate 6 is a semiconductor refrigeration plate; During the heat dissipation operation, the motor 17 drives the guide roller 16 to rotate, driving the heat-conducting metal belt 7 attached to the electronic control component 2 to circulate, and the cooling surface of the refrigeration plate 6 is attached to the heat-conducting metal belt 7, thereby maintaining the refrigeration plate 6 at a low temperature and taking away the heat on the heat-conducting metal belt 7; When the electronic control component 2 of the smart screen generates heat, the heat-conducting metal belt 7 quickly conducts the heat to the cooling surface of the cooling plate 6. The cooling plate 6 starts cooling, transfers the heat from the cooling surface to the heat dissipation surface and sends it into the water cooling chamber 5, thereby achieving efficient cooling of the electronic control component 2; This solves the problem of untimely heat dissipation of the electronic control component 2 in the prior art. Compared with the traditional heat dissipation method, it can reduce the temperature of the electronic control component 2 more quickly and accurately to ensure its stable operation; Furthermore, the heat dissipation surface area of ​​the heat dissipation mechanism in the device can be effectively increased by the circular rotation structure of the heat-conducting metal belt 7; The driving module includes four guide rollers 16 rotatably connected to the heat dissipation housing 3, and the four guide rollers 16 are all in contact with the heat conductive metal belt 7. A motor 17 is installed on the top surface of the heat dissipation housing 3, and the output shaft end of the motor 17 is fixedly connected to a guide roller 16; The motor 17 is installed on the top surface of the heat dissipation housing 3, and its output shaft end is fixedly connected to a guide roller 16, driving the four guide rollers 16 to rotate, and then driving the heat-conducting metal belt 7 to circulate. During the operation of the smart screen, this driving method can ensure that the heat-conducting metal belt 7 circulates continuously and stably, continuously transferring the heat generated by the electronic control component 2, and providing a stable heat transfer basis for the subsequent heat dissipation link; A heat dissipation fin plate 8 is slidably mounted on the heat dissipation surface of the refrigeration plate 6 and can reciprocate; A plurality of heat transfer grooves 27 are provided on the heat dissipation surface of the refrigeration plate 6 and are slidably connected to the heat dissipation fin plate 8. The heat transfer grooves 27 are T-shaped grooves. A group of heat dissipation fin strips 28 are installed on the heat dissipation fin plate 8. The T-shaped heat transfer groove 27 on the heat dissipation surface of the refrigeration plate 6 is slidably connected to the heat dissipation fin plate 8, and the heat dissipation fins 28 on the heat dissipation fin plate 8 increase the heat dissipation area. When the refrigeration plate 6 transfers heat to the heat dissipation surface, the heat dissipation fin plate 8 reciprocates within a certain range, and its heat dissipation fins 28 are in full contact with the water-cooling liquid in the water-cooling cavity 5, accelerating the heat dissipation into the water-cooling cavity 5. This solves the problem of low heat dissipation efficiency of the heat dissipation surface of the refrigeration plate 6. Compared with the heat dissipation device without a movable heat dissipation fin plate 8, the heat dissipation effect is significantly enhanced, and the overall heat dissipation is improved; Furthermore, by reciprocating the heat dissipation fin plate 8 within a certain range under the water cooling state, the generation rate of the water cooling diaphragm on the heat dissipation fin plate 8 and the heat dissipation fin strip 28 can be effectively reduced, and the water cooling liquid in the water cooling chamber 5 is continuously in contact with the heat dissipation fin plate 8 and the heat dissipation fin strip 28, thereby maintaining the high heat exchange efficiency of the heat dissipation fin plate 8 and the heat dissipation fin strip 28; A liquid vibrating plate 9 is slidably mounted on the bottom of the water cooling chamber 5, and a sealing strip is fixedly arranged at the sliding connection between the liquid vibrating plate 9 and the water cooling chamber 5; A motor 10 and a reciprocating drive assembly driven by the motor 10 to reciprocate the liquid oscillating plate 9 up and down are arranged in the heat dissipation housing 3; The reciprocating drive assembly includes a synchronous shaft 19 installed on the output shaft end of the motor 10 and a horizontal shaft 20 rotatably connected to the heat dissipation housing 3.

A first missing gear 21 is installed on the horizontal shaft 20, and a first transmission tooth surface is fixedly provided on the first missing gear 21. A reciprocating tooth plate 22 is fixedly installed on the top surface of the liquid oscillating plate 9, and the first transmission tooth surface is transmission-connected to the first missing gear 21. A plurality of first return springs 23 are installed between the liquid oscillating plate 9 and the heat dissipation housing 3; The motor 10 drives the synchronous shaft 19 to rotate, and drives the horizontal shaft 20 to rotate through the first bevel gear. The first transmission tooth surface of the first missing gear 21 on the horizontal shaft 20 is connected to the reciprocating tooth plate 22 on the liquid oscillating plate 9, and cooperates with the first return spring 23 to make the liquid oscillating plate 9 reciprocate up and down. During the heat dissipation process of the smart screen, the reciprocating motion of the liquid vibrating plate 9 can enhance the fluidity of the coolant in the water-cooling cavity 5 and promote heat exchange. At the same time, the movement of the liquid vibrating plate 9 can also drive the heat dissipation mechanism thereon to work and improve the heat dissipation efficiency. This design solves the problems of poor coolant fluidity and uneven heat dissipation in the water-cooling cavity 5. Compared with the traditional water cooling method, it improves the uniformity and heat dissipation effect of water cooling. It also includes a reciprocating rack 24 installed on the two heat dissipation fin plates 8 and a second missing gear 25 installed on the synchronization shaft 19, the two reciprocating racks 24 are respectively arranged on both sides of the second missing gear 25, the second missing gear 25 is provided with a second transmission tooth surface, the second transmission tooth surface is adaptively connected to the reciprocating rack 24, and a second return spring 26 limited by the heat dissipation housing 3 is installed on the side of the heat dissipation fin plate 8; The central angles corresponding to the first transmission tooth surface and the second transmission tooth surface are both 60°; The second missing gear 25 on the synchronization shaft 19 is adapted to be connected with the reciprocating rack 24 on the heat dissipation fin plate 8, and the second reset spring 26 resets the heat dissipation fin plate 8. When the synchronization shaft 19 rotates, the second transmission tooth surface of the second missing gear 25 intermittently contacts the reciprocating rack 24, driving the heat dissipation fin plate 8 to move back and forth; During the heat dissipation process of the refrigeration plate 6, this intermittent driving mode can make the heat dissipation fin plate 8 dissipate heat more efficiently, avoiding the heat dissipation unevenness caused by the heat dissipation fin plate 8 being in the same position for a long time, and the design of the 60° central angle ensures the periodicity and stability of the drive, solves the problem of inaccurate motion control of the heat dissipation fin plate 8 and limited heat dissipation efficiency, and improves the heat dissipation effect of the heat dissipation fin plate 8 and the overall heat dissipation performance of the device; A cooling liquid circulation system and two heat dissipation rotary cylinders 11 are installed on the liquid vibration plate 9; The two ends of the heat dissipation drum 11 are respectively connected to the two air cooling chambers 4, and a spiral stirring blade 12 is installed on the heat dissipation drum 11. A water-cooling shaft 13 is rotatably installed on the inner wall of the heat dissipation drum 11.

The spiral stirring blades 12 on the heat dissipation rotor 11 accelerate the air flow in the air-cooling chamber 4. The water-cooling flow channel in the water-cooling shaft 13 is connected to the coolant circulation system. The heat dissipation fin tube 15 in the heat conduction module rotates under the meshing action of the driven bevel gear and the fixed bevel gear ring 14. When the smart screen is working, air cooling and water cooling work together to accelerate heat dissipation. The heat dissipation fin tube 15 is perpendicular to the water cooling shaft 13 and is provided with a heat dissipation fin plate 36. The copper heat dissipation fin tube 15, the heat dissipation fin plate 36, the heat conductive metal belt 7 and the heat dissipation drum 11 can efficiently conduct heat. This design solves the problem that the existing heat dissipation device has a single heat dissipation method and low heat dissipation efficiency. Compared with the traditional heat dissipation mechanism, it realizes the efficient combination of air cooling and water cooling, and greatly improves the heat dissipation efficiency. By setting the rotation and vibration state of the heat dissipation fin tube 15 and the heat dissipation rotary cylinder 11 during operation, the residual rate of air-cooled impurities on the heat dissipation fin tube 15 and the heat dissipation rotary cylinder 11 can also be effectively reduced; The synchronous revolution and rotation structure of the heat dissipation fin tube 15 can dissipate the heat on the heat dissipation fin tube 15 in all directions and make the heat dissipation fin tube 15 circulate and contact with the heat dissipation cooling air, thereby improving the heat dissipation and heat exhaust efficiency of the heat dissipation fin tube 15; It also includes a sleeve shaft 29 rotatably connected to the liquid oscillating plate 9, a synchronous groove with openings at both ends fixedly opened inside the sleeve shaft 29 and slidably connected to the synchronous shaft 19, the cross-sections of the synchronous groove and the synchronous shaft 19 are both regular hexagons, a synchronous transmission belt is installed on the sleeve shaft 29, the heat dissipation rotary cylinder 11 is connected to the synchronous transmission belt, a steering shaft 30 is rotatably installed on the liquid oscillating plate 9 and corresponding to the positions of the two heat dissipation rotary cylinders 11, a steering bevel gear is installed on the steering shaft 30, a second bevel gear is installed on the heat dissipation rotary cylinder 11 and the water-cooling shaft 13, the two second bevel gears are connected to the steering bevel gear, and the two second bevel gears are respectively arranged on both sides of the steering bevel gear; The synchronous shaft 19 drives the sleeve shaft 29 to rotate, and the sleeve shaft 29 drives the heat dissipation drum 11 to rotate through the synchronous transmission belt. The steering bevel gear on the steering shaft 30 is connected with the heat dissipation drum 11 and the second bevel gear on the water-cooling shaft 13, so that the heat dissipation drum 11 and the water-cooling shaft 13 rotate coaxially and in opposite directions. When the smart screen is dissipating heat, this transmission structure ensures that the heat dissipation rotor 11 and the water-cooling shaft 13 operate stably and efficiently, ensures the normal operation of the heat dissipation mechanism, improves the stability and reliability of the heat dissipation system, solves the problem of unstable transmission of components in the heat dissipation mechanism and affecting the heat dissipation effect, and optimizes the operating performance of the heat dissipation mechanism compared to the traditional transmission method; A spray cooling unit for spray cooling the heat-conducting metal belt 7 is provided in the heat dissipation housing 3 .

[0022] The coolant circulation system includes a circulation pump 31 installed in the heat dissipation shell 3, the suction end of the circulation pump 31 is connected to the water cooling chamber 5, the discharge end of the circulation pump 31 is connected to a water cooling channel through a first hose, a second hose is connected between the other water cooling channel and the water cooling chamber 5, a through pipe is connected between the two water cooling channels, and a temperature probe 32 for monitoring the temperature of the water cooling liquid in the water cooling chamber 5 is installed in the heat dissipation shell 3.

[0023] The circulation pump 31 extracts the coolant in the water-cooling chamber 5 and sends it into the water-cooling channel through the first hose. After the coolant circulates in the water-cooling channel, it flows back to the water chamber through the second hose and the through pipe. The temperature probe 32 monitors the temperature of the water-cooling liquid in real time. During the heat dissipation process of the smart screen, the coolant circulation system can continuously take away the heat transferred from the heat dissipation surface of the cooling plate 6 to the water cooling chamber 5, ensuring the temperature of the water cooling chamber 5 to be stable and ensuring the normal operation of the cooling plate 6; This system solves the problems of poor coolant circulation and temperature control in water cooling. Compared with the traditional coolant circulation method, it realizes efficient circulation and precise temperature control of the coolant, and improves the stability of the cooling system. The spray cooling unit includes a refrigerant storage tank 33 installed in the heat dissipation shell 3 and a spray pipe 34 installed in the heat dissipation shell 3.

The spray outlet end of the spray pump is connected to the inner cavity of the spray pipe 34. The spray pipe 34 is provided with a group of spray holes 35 facing the heat-conducting metal belt 7.

[0024] The spray pump draws refrigerant from the refrigerant storage tank 33 and sprays the refrigerant to the heat-conducting metal belt 7 through the spray holes 35 on the spray pipe 34; When the smart screen electronic control component 2 generates a large amount of heat and air cooling and water cooling alone cannot meet the heat dissipation requirements, the spray cooling unit is started, and the refrigerant spray quickly reduces the temperature of the heat-conducting metal belt 7, thereby reducing the temperature of the electronic control component 2. This solves the problem of insufficient heat dissipation of the smart screen under high-load operation. Compared with the traditional single heat dissipation method, the addition of spray cooling as an auxiliary heat dissipation method significantly improves the heat dissipation capacity of the heat dissipation device under extreme conditions, ensuring the stable operation of the smart screen under complex working conditions.

First, the smart screen is running, the electronic control component 2 generates heat, the heat dissipation device is started, and in the driving module, the motor 17 drives the guide roller 16 to rotate, so that the heat-conducting metal belt 7 that is in contact with the electronic control component 2 rotates in a circular manner, and the heat of the electronic control component 2 is transferred to the cooling surface of the refrigeration plate 6 that is in contact with it. The refrigeration plate 6 starts refrigeration, transfers the heat to the heat dissipation surface and sends it into the water-cooling cavity 5. At the same time, the axial flow fan in the ventilation tube 18 introduces external cold air into the air-cooling chamber 4, and the filter element filters dust and impurities. The cold air and the heat dissipation mechanism cooperate to dissipate heat. In the water-cooling chamber 5, the motor 10 drives the synchronous shaft 19 to rotate, and drives the horizontal shaft 20 through the first bevel gear, so that the first transmission tooth surface of the first missing gear 21 on the horizontal shaft 20 is connected with the reciprocating tooth plate 22 on the top surface of the vibrating plate 9, and cooperates with the first return spring 23 to make the vibrating plate 9 reciprocate up and down, thereby enhancing the fluidity of the coolant and promoting heat exchange. The rotation of the synchronous shaft 19 also drives the second missing gear 25, and its second transmission tooth surface intermittently contacts the reciprocating rack 24 on the heat dissipation fin plate 8. Under the action of the second return spring 26, the heat dissipation fin plate 8 reciprocates on the heat dissipation surface of the refrigeration plate 6, and the heat dissipation fin plate 8 The heat dissipation fins 28 on the cooling plate are in full contact with the water-cooling liquid to accelerate heat dissipation. In the heat dissipation mechanism on the vibrating plate 9, the motor 10 drives the heat dissipation rotor 11 and the water-cooling shaft 13 to rotate coaxially and in opposite directions. The spiral stirring blades 12 on the heat dissipation rotor 11 accelerate the air flow in the air-cooling chamber 4. The water-cooling flow channel in the water-cooling shaft 13 is connected to the coolant circulation system. The circulating pump 31 extracts the coolant in the water-cooling cavity 5 and sends it into the water-cooling flow channel through the first hose. After the coolant circulates, it flows back to the water cavity through the second hose and the through pipe. The temperature probe 32 monitors the water-cooling liquid temperature in real time to ensure that the temperature of the water-cooling cavity 5 is stable. The fixed cone gear ring 1 of the heat conduction module on the water-cooling shaft 13 4 is meshed with the driven bevel gear on the heat dissipation fin tube 15 to rotate the heat dissipation fin tube 15, which is perpendicular to the water-cooling shaft 13 and has a heat dissipation fin plate 36. The copper heat dissipation fin tube 15, the heat dissipation fin plate 36, the heat conduction metal belt 7 and the heat dissipation drum 11 efficiently conduct heat. When the heat of the smart screen electronic control component 2 is too high and air cooling and water cooling cannot meet the heat dissipation requirements, the spray cooling unit is started, and the spray pump draws refrigerant from the refrigerant storage tank 33, and sprays the heat conduction metal belt 7 through the spray hole 35 on the spray pipe 34 to cool it, thereby reducing the temperature of the electronic control component 2, thereby fully ensuring the stable operation of the smart screen under various working conditions.
