[0004] 2. Unable to balance local high temperature in a timely manner: When the existing smart screen heat dissipation device faces the high temperature generated locally by the electronic control components, it cannot quickly conduct and dissipate the heat, resulting in a continuous increase in the local temperature and affecting the normal operation of related components;

[0005] 3. The heat dissipation method is single and it is not convenient to achieve multi-effect heat dissipation, and it is not convenient to use the vibration movement and rotation movement of the heat dissipation mechanism to improve the heat dissipation efficiency and effect of the heat dissipation mechanism;

The heat dissipation mechanism of the traditional heat dissipation device is not convenient to perform circular motion relative to the heat source and perform circular refrigeration on the heat source, and the existing heat dissipation mechanism is not convenient to increase the heat dissipation surface area relative to the heat source;

[0007] Based on this, the present invention provides a smart screen heat dissipation device with a temperature compensation function to solve the technical problems proposed in the above background art. Summary of the Invention

[0018] As a preferred technical solution of the present invention, it further includes a sleeve shaft rotatably connected to the vibration liquid plate.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. The present invention monitors the temperature of the coolant in the water-cooling chamber in real time through a temperature probe. When a large amount of heat is generated by the electronic control component of the smart screen, relying solely on air cooling and water cooling cannot meet the heat dissipation requirements. This is in sharp contrast to the lack of adaptive adjustment ability in the prior art, where the heat dissipation strategy cannot be adjusted in a timely manner according to the real-time temperature change and temperature compensation cannot be carried out. This design can dynamically adjust the heat dissipation method according to the real-time temperature during the operation of the smart screen, achieve precise temperature compensation, and ensure the stable operation of the smart screen under different working loads.

[0024] 2. This device uses a heat-conducting metal belt that fits and rotates cyclically with the electronic control component, which can quickly conduct the high temperature generated locally by the electronic control component to the refrigeration plate. The refrigeration plate then transfers the heat to the water-cooling chamber. At the same time, the heat dissipation fin plate that can reciprocate on the heat dissipation surface of the refrigeration plate increases the heat dissipation area and accelerates the heat dissipation to the water-cooling chamber. This solves the problem that the existing heat dissipation device of the smart screen cannot quickly conduct and dissipate heat when facing the local high temperature of the electronic control component, avoids the continuous increase of the local temperature, and ensures the normal operation of the relevant components.

[0025] 3. The present invention comprehensively uses three heat dissipation methods: air cooling, water cooling, and spray refrigeration. The axial flow fan in the ventilation tube introduces external cold air for air cooling, the water-cooling chamber and the coolant circulation system achieve water cooling, and the spray cooling unit assists in heat dissipation under high load. In addition, the motor drives the vibration liquid plate to reciprocate up and down to enhance the fluidity of the coolant in the water-cooling chamber, the heat dissipation rotating cylinder and the water-cooling shaft rotate coaxially in opposite directions, the spiral stirrer accelerates the air flow in the air-cooling chamber, and the heat dissipation fin tube rotates under the meshing action of the driven bevel gear and the fixed bevel gear ring. These movements all improve the heat dissipation efficiency and effect. Different from the single heat dissipation method in the prior art, the present invention significantly improves the overall heat dissipation performance through the coordinated work of multiple heat dissipation methods and the movement of each component.

[0026] 4. In the present invention, the heat-conducting metal belt rotates cyclically, which can not only continuously transfer the heat of the electronic control component, but also increase the heat dissipation surface area of the heat dissipation mechanism. At the same time, the heat dissipation fin tube rotates synchronously in a revolution and rotation manner during operation, which can dissipate heat in all directions and cyclically contact with the heat dissipation and cooling air. Compared with the traditional heat dissipation device, the heat dissipation mechanism of the present invention can perform circular motion relative to the heat source, more efficiently perform circular refrigeration on the heat source, and greatly improve the heat dissipation efficiency and heat dissipation effect.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] As Figures 1 to 12 shown, the present invention provides a smart screen heat dissipation device with a temperature compensation function, including a screen panel 1 and an electronic control component 2 electrically connected to the screen panel 1. It further includes a heat dissipation housing 3 installed at the rear side of the screen panel 1. Two air-cooling chambers 4 and a water-cooling cavity 5 are provided in the heat dissipation housing 3.

[0042] The two air-cooling chambers 4 are respectively arranged at the upper and lower ends of the water-cooling cavity 5.

[0043] Two ventilation tubes 18 are installed on the heat dissipation housing 3 corresponding to the positions of the two air-cooling chambers 4 and on the back surface of the heat dissipation housing 3. An axial flow fan and a filter element are respectively installed on the inner wall of the ventilation tube 18 from the inside to the outside.

[0044] The two air-cooling chambers 4 are respectively arranged at the upper and lower ends of the water-cooling cavity 5. Two ventilation tubes 18 are installed on the heat dissipation housing 3 corresponding to the positions of the air-cooling chambers 4 and on the back surface. The axial flow fan in the ventilation tube 18 can quickly introduce external cold air into the air-cooling chamber 4. At the same time, the filter element can effectively filter dust and impurities in the air, preventing them from entering the interior of the heat dissipation device and affecting the heat dissipation effect or damaging components.

[0045] When the smart screen is working, the external cold air enters the air-cooling chamber 4 through the ventilation tube 18, works together with the heat dissipation mechanism to take away heat, and realizes efficient air-cooling heat dissipation. It solves the problems of poor air-cooling effect and easy dust influence of the existing smart screen heat dissipation device. Compared with the existing technology, it improves the heat dissipation efficiency and extends the service life of the device.

[0046] A driving module and two symmetrically arranged refrigeration plates 6 are installed in the heat dissipation housing 3. A heat-conducting metal belt 7 that can rotate in a cycle and is in contact with the electronic control component 2 is installed on the driving module in a transmission manner. The refrigerating surfaces of the two refrigeration plates 6 are both in contact with the heat-conducting metal belt 7, and the radiating surfaces of the two refrigeration plates 6 both extend into the water-cooling cavity 5.

[0047] The refrigeration plate 6 is a semiconductor refrigeration plate.

[0048] During the heat dissipation operation, the motor 17 drives the guide roller 16 to rotate, driving the heat-conducting metal belt 7 in contact with the electronic control component 2 to rotate in a cycle. The refrigerating surface of the refrigeration plate 6 is in contact with the heat-conducting metal belt 7, thereby maintaining the refrigeration plate 6 at a low temperature state and taking away the heat on the heat-conducting metal belt 7.

[0049] When the electronic control component 2 of the smart screen generates heat, the heat-conducting metal strip 7 quickly conducts the heat to the refrigerating surface of the refrigerating plate 6. The refrigerating plate 6 starts refrigeration, transfers the heat from the refrigerating surface to the heat-dissipating surface and sends it into the water-cooling cavity 5, realizing efficient cooling of the electronic control component 2;

[0050] 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, ensuring its stable operation;

[0051] Moreover, through the setting of the circulating rotation structure of the heat-conducting metal strip 7, the heat dissipation surface area of the heat dissipation mechanism in this device can be effectively increased;

[0052] The driving module includes four guide rollers 16 rotatably connected inside the heat dissipation housing 3. All four guide rollers 16 are in contact with the heat-conducting metal strip 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 one of the guide rollers 16;

[0053] The motor 17 is installed on the top surface of the heat dissipation housing 3, and its output shaft end is fixedly connected to one of the guide rollers 16, driving the four guide rollers 16 to rotate, and then driving the heat-conducting metal strip 7 to circulate and rotate. During the operation of the smart screen, this driving method can ensure the continuous and stable circulation of the heat-conducting metal strip 7, continuously transfer the heat generated by the electronic control component 2, and provide a stable heat transfer basis for the subsequent heat dissipation link;

[0054] A reciprocating movable heat dissipation fin plate 8 is slidably installed on the heat dissipation surface of the refrigerating plate 6;

[0055] A plurality of heat transfer guide grooves 27 slidably connected to the heat dissipation fin plate 8 are provided on the heat dissipation surface of the refrigerating plate 6. The heat transfer guide grooves 27 are T-shaped grooves, and a group of heat dissipation fin strips 28 are installed on the heat dissipation fin plate 8;

[0056] The T-shaped heat transfer guide grooves 27 on the heat dissipation surface of the refrigerating plate 6 are slidably connected to the heat dissipation fin plate 8. The heat dissipation fin strips 28 on the heat dissipation fin plate 8 increase the heat dissipation area. When the refrigerating plate 6 transfers heat to the heat dissipation surface, the heat dissipation fin plate 8 reciprocates within a certain range, and its heat dissipation fin strips 28 are in full contact with the water-cooling liquid in the water-cooling cavity 5, accelerating the heat dissipation to the water-cooling cavity 5. This solves the problem of low heat dissipation efficiency of the heat dissipation surface of the refrigerating plate 6. Compared with the heat dissipation device without the movable heat dissipation fin plate 8, the heat dissipation effect is significantly enhanced, and the overall heat dissipation performance is improved;

[0057] Moreover, through the reciprocating movement of 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 strips 28 can be effectively reduced, and the water-cooling liquid in the water-cooling cavity 5 is continuously in new contact with the heat dissipation fin plate 8 and the heat dissipation fin strips 28, thereby maintaining the high heat exchange efficiency of the heat dissipation fin plate 8 and the heat dissipation fin strips 28;

[0058] A vibration liquid plate 9 is slidably installed at the bottom of the water cooling cavity 5, and a sealing strip is fixedly arranged at the sliding connection between the vibration liquid plate 9 and the water cooling cavity 5;

[0059] A motor 10 and a reciprocating drive assembly for driving the vibration liquid plate 9 to reciprocate up and down by the motor 10 are arranged in the heat dissipation housing 3;

[0060] The reciprocating drive assembly includes a synchronous shaft 19 installed at the output shaft end of the motor 10 and a transverse shaft 20 rotatably connected to the heat dissipation housing 3. First bevel gears are installed on both the synchronous shaft 19 and the transverse shaft 20, and the two first bevel gears mesh with each other. A first missing gear 21 is installed on the transverse shaft 20, a first transmission tooth surface is fixedly arranged on the first missing gear 21, a reciprocating tooth plate 22 is fixedly installed on the top surface of the vibration liquid plate 9, the first transmission tooth surface is in transmission connection with the first missing gear 21, and a plurality of first return springs 23 are installed between the vibration liquid plate 9 and the heat dissipation housing 3;

[0061] The motor 10 drives the synchronous shaft 19 to rotate, drives the transverse shaft 20 to rotate through the first bevel gear, the first transmission tooth surface of the first missing gear 21 on the transverse shaft 20 is in transmission connection with the reciprocating tooth plate 22 on the vibration liquid plate 9, and with the cooperation of the first return spring 23, the vibration liquid plate 9 reciprocates up and down;

[0062] During the heat dissipation process of the smart screen, the reciprocating movement of the vibration liquid plate 9 can enhance the fluidity of the coolant in the water cooling cavity 5, promote heat exchange. At the same time, the movement of the vibration liquid plate 9 can also drive the heat dissipation mechanism thereon to work, improving the heat dissipation efficiency. This design solves the problems of poor fluidity of the coolant in the water cooling cavity 5 and uneven heat dissipation. Compared with the traditional water cooling method, it improves the uniformity and heat dissipation effect of water cooling;

[0063] It further includes a reciprocating rack 24 installed on two heat dissipation fin plates 8 and a second missing gear 25 installed on the synchronous shaft 19. The two reciprocating racks 24 are respectively arranged on both sides of the second missing gear 25. A second transmission tooth surface is arranged on the second missing gear 25, the second transmission tooth surface is adaptively connected with the reciprocating rack 24, and a second return spring 26 limited by the heat dissipation housing 3 is installed on the side surface of the heat dissipation fin plate 8;

[0064] The central angles corresponding to the first transmission tooth surface and the second transmission tooth surface are both 60°;

[0065] The second missing gear 25 on the synchronous shaft 19 is adaptively connected with the reciprocating rack 24 on the heat dissipation fin plate 8, the second return spring 26 makes the heat dissipation fin plate 8 reset. When the synchronous 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 reciprocate;

[0066] During the heat dissipation process of the refrigeration plate 6, this intermittent driving method can enable the heat dissipation fin plate 8 to dissipate heat more efficiently, avoiding uneven heat dissipation caused by the heat dissipation fin plate 8 staying in the same position for a long time. Moreover, the design of a 60° central angle ensures the periodicity and stability of the driving, solves the problems of inaccurate motion control and limited heat dissipation efficiency of the heat dissipation fin plate 8, and improves the heat dissipation effect of the heat dissipation fin plate 8 and the overall heat dissipation performance of the device;

[0067] A coolant circulation system and two heat dissipation rotating cylinders 11 are installed on the vibration liquid plate 9;

[0068] Both ends of the heat dissipation rotating cylinder 11 are respectively communicated with two air-cooling chambers 4. A spiral stirring blade 12 is installed on the heat dissipation rotating cylinder 11. A water-cooling shaft 13 is rotatably installed on the inner wall of the heat dissipation rotating cylinder 11. The heat dissipation rotating cylinder 11 and the water-cooling shaft 13 are driven by a motor 10 and rotate coaxially in opposite directions. A water-cooling flow channel communicated with the coolant circulation system is arranged in the water-cooling shaft 13, and a group of heat conduction modules distributed in a linear array are installed on the water-cooling shaft 13;

[0069] Each heat conduction module includes a fixed bevel gear ring 14 installed in the heat dissipation rotating cylinder 11. A plurality of heat dissipation fin tubes 15 are rotatably communicated with the water-cooling flow channel. A driven bevel gear meshing with the fixed bevel gear ring 14 is installed on each heat dissipation fin tube 15;

[0070] The heat dissipation fin tube 15 is vertically arranged with the water-cooling shaft 13, and a group of heat dissipation fin disk 36 is installed on the heat dissipation fin tube 15;

[0071] The heat dissipation fin tube 15, the heat dissipation fin disk 36, the heat conduction metal strip 7 and the heat dissipation rotating cylinder 11 are all made of copper;

[0072] The motor 10 drives the heat dissipation rotating cylinder 11 and the water-cooling shaft 13 to rotate coaxially in opposite directions. The spiral stirring blade 12 on the heat dissipation rotating cylinder 11 accelerates the air flow in the air-cooling chamber 4. The water-cooling flow channel in the water-cooling shaft 13 is communicated with the coolant circulation system, and 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;

[0073] When the intelligent screen works, 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 disk 36. The copper-made heat dissipation fin tube 15, heat dissipation fin disk 36, heat conduction metal strip 7 and heat dissipation rotating cylinder 11 can conduct heat efficiently. This design solves the problems of single heat dissipation method and low heat dissipation efficiency of the existing heat dissipation device. 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;

[0074] By setting the rotation and vibration states during the operation of the heat dissipation fin tube 15 and the heat dissipation rotating cylinder 11, the residual rate of air-cooled impurities on the heat dissipation fin tube 15 and the heat dissipation rotating cylinder 11 can also be effectively reduced;

[0075] The synchronous revolution and rotation structure setting during heat dissipation through the heat dissipation finned tube 15 enables the heat on the heat dissipation finned tube 15 to be dissipated in all directions and enables the heat dissipation finned tube 15 to circulate in contact with the heat dissipation and cooling air, thereby improving the heat dissipation and heat removal efficiency of the heat dissipation finned tube 15;

[0076] It further includes a sleeve shaft 29 rotatably connected to the vibration liquid plate 9. A synchronous groove with both ends open and slidably connected to the synchronous shaft 19 is fixedly opened inside the sleeve shaft 29. The cross-sections of the synchronous groove and the synchronous shaft 19 are both regular hexagons. A synchronous transmission belt is drivingly installed on the sleeve shaft 29. The heat dissipation rotating cylinder 11 is drivingly connected to the synchronous transmission belt. Steering shafts 30 are rotatably installed on the vibration liquid plate 9 at positions corresponding to the two heat dissipation rotating cylinders 11. A steering bevel gear is installed on the steering shaft 30. Second bevel gears are installed on both the heat dissipation rotating cylinder 11 and the water-cooled shaft 13. The two second bevel gears are both drivingly connected to the steering bevel gear, and the two second bevel gears are respectively arranged on both sides of the steering bevel gear;

[0077] The synchronous shaft 19 drives the sleeve shaft 29 to rotate. The sleeve shaft 29 drives the heat dissipation rotating cylinder 11 to rotate through the synchronous transmission belt. The steering bevel gear on the steering shaft 30 is drivingly connected to the second bevel gears on the heat dissipation rotating cylinder 11 and the water-cooled shaft 13, so that the heat dissipation rotating cylinder 11 and the water-cooled shaft 13 rotate coaxially in opposite directions;

[0078] During the heat dissipation of the intelligent screen, this transmission structure ensures the stable and efficient operation of the heat dissipation rotating cylinder 11 and the water-cooled shaft 13, 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 operation performance of the heat dissipation mechanism compared with the traditional transmission method;

[0079] A spray cooling unit for spray-cooling the heat-conducting metal strip 7 is provided inside the heat dissipation housing 3.

[0080] The coolant circulation system includes a circulation pump 31 installed inside the heat dissipation housing 3. The liquid suction end of the circulation pump 31 is communicated with the water-cooled cavity 5. The liquid discharge end of the circulation pump 31 is connected to a water-cooled flow channel through a first hose. A second hose is connected between the other water-cooled flow channel and the water-cooled cavity 5. A through pipe is connected between the two water-cooled flow channels. A temperature probe 32 for monitoring the temperature of the coolant in the water-cooled cavity 5 is installed inside the heat dissipation housing 3.

[0081] The circulation pump 31 pumps out the coolant in the water-cooled cavity 5 and sends it into the water-cooled flow channel through the first hose. After the coolant circulates in the water-cooled flow channel, it flows back to the water cavity through the second hose and the through pipe. The temperature probe 32 monitors the coolant temperature in real time;

[0082] During the heat dissipation process of the intelligent screen, the coolant circulation system can continuously take away the heat transferred from the heat dissipation surface of the refrigeration plate 6 to the water-cooled cavity 5, ensure the stable temperature of the water-cooled cavity 5, and ensure the normal operation of the refrigeration plate 6;

[0083] This system solves the problems of poor coolant circulation and ineffective temperature control in water-cooled heat dissipation. Compared with traditional coolant circulation methods, it achieves efficient coolant circulation and precise temperature control, improving the stability of the heat dissipation system.

[0084] The spray cooling unit includes a refrigerant storage tank 33 installed in the heat dissipation housing 3 and a spray pipe 34 installed on the heat dissipation housing 3. A spray pump is built into the heat dissipation housing 3. The spray pump feeds liquid through the refrigerant storage tank 33. The mist outlet end of the spray pump is communicated with the inner cavity of the spray pipe 34. A set of spray holes 35 facing the heat-conducting metal strip 7 are provided on the spray pipe 34.

[0085] The spray pump extracts the refrigerant from the refrigerant storage tank 33 and sprays the refrigerant on the heat-conducting metal strip 7 through the spray holes 35 on the spray pipe 34 for refrigeration.

[0086] When the intelligent screen electronic control component 2 generates a large amount of heat and the heat dissipation requirements cannot be met only by air cooling and water cooling, the spray cooling unit is activated. The refrigerant spray rapidly reduces the temperature of the heat-conducting metal strip 7, thereby reducing the temperature of the electronic control component 2. This solves the problem of insufficient heat dissipation of the intelligent screen under high-load operation. Compared with traditional single heat dissipation methods, the addition of spray refrigeration as an auxiliary heat dissipation means significantly improves the heat dissipation capacity of the heat dissipation device in extreme situations and ensures the stable operation of the intelligent screen under complex working conditions.

[0087] The working principle and usage process of the present invention:

[0088] When the intelligent screen heat dissipation device of the present invention is working, each component operates in coordination to achieve efficient heat dissipation. First, when the intelligent screen runs, the electronic control component 2 generates heat, and the heat dissipation device starts. In the drive module, the motor 17 drives the guide roller 16 to rotate, causing the heat-conducting metal belt 7 in contact with the electronic control component 2 to rotate cyclically, conducting the heat of the electronic control component 2 to the refrigerating surface of the refrigerating plate 6 in contact with it. The refrigerating 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 cylinder 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 dissipate heat in coordination. In the water-cooling cavity 5, the motor 10 drives the synchronous shaft 19 to rotate, 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 in transmission connection with the reciprocating tooth plate 22 on the top surface of the vibration liquid plate 9. Cooperating with the first return spring 23, the vibration liquid plate 9 moves up and down reciprocally, 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 reciprocally moves on the heat dissipation surface of the refrigerating plate 6. The heat dissipation fins 28 on the heat dissipation fin plate 8 are in full contact with the water-cooling liquid, accelerating heat dissipation. In the heat dissipation mechanism on the vibration liquid plate 9, the motor 10 drives the heat dissipation rotating cylinder 11 and the water-cooling shaft 13 to rotate coaxially in opposite directions. The spiral stirring blades 12 on the heat dissipation rotating cylinder 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 circulation pump 31 pumps out the coolant in the water-cooling cavity 5, sends it into the water-cooling flow channel through the first hose, and the coolant returns to the water cavity after circulation through the second hose and the through pipe. The temperature probe 32 monitors the temperature of the water-cooling liquid in real time to ensure the stable temperature of the water-cooling cavity 5. The fixed bevel gear ring 14 of the heat conduction module on the water-cooling shaft 13 meshes with the driven bevel gear on the heat dissipation fin tube 15, causing the heat dissipation fin tube 15 to rotate. It is perpendicular to the water-cooling shaft 13 and is provided with a heat dissipation fin disk 36. The heat dissipation fin tube 15, the heat dissipation fin disk 36, the heat-conducting metal belt 7 and the heat dissipation rotating cylinder 11 made of copper efficiently conduct heat. When the heat of the intelligent screen electronic control component 2 is too high and air cooling and water cooling cannot meet the heat dissipation requirements, the spray cooling unit starts. The spray pump extracts the refrigerant from the refrigerant storage tank 33 and sprays the refrigerant through the spray holes 35 on the spray pipe 34 onto the heat-conducting metal belt 7 for spray refrigeration, reducing the temperature of the electronic control component 2, thereby comprehensively ensuring the stable operation of the intelligent screen under various working conditions.
