[0002] With the development of display technology, Micro LED technology has emerged. Micro LED is a technology that assembles micron-sized self-luminous LED chips onto a driving panel to form a high-density array. It has the advantages of high brightness, high resolution, and high contrast.

[0003] Since a single chip of Micro LED is extremely small, after being integrated in a large number of display panels, a large amount of heat will be generated during high-power operation. At the same time, its miniaturization and high integration make it easy for heat to accumulate in a small space, and heat conduction is also difficult. In addition, chips of different colors generate heat differently, which will affect the stability of the color. Therefore, Micro LED has very high requirements for the heat dissipation system. Air cooling is used in related technologies to solve the heat dissipation needs of Micro LED, but air cooling has the defect of low heat dissipation efficiency. Summary of the invention

[0039] Compared with the prior art, the beneficial effects of this application are:

[0040] 1. On the basis of defining the water inlet three-way solenoid valve as a one-in-two-out three-way solenoid valve, the reversing three-way solenoid valve A as a one-in-two-out three-way solenoid valve, and the reversing three-way solenoid valve B as a one-in-two-out three-way solenoid valve; by defining the first selected connecting end to be connected with the second continuous connecting end, the third selected connecting end to be connected with the first interface end, the second interface end to be connected with the third continuous connecting end, and the fifth selected connecting end to be connected with the seventh selected connecting end.

[0062] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 A schematic diagram of a water-cooling heat dissipation system based on a Micro LED module in an embodiment of the present application is shown. A water-cooling heat dissipation system based on a Micro LED module provided in an embodiment of the present application includes: a Micro LED screen 11, a heat-conducting support plate, a water inlet three-way solenoid valve 63, a reversing three-way solenoid valve A61, a reversing three-way solenoid valve B62, a three-way water outlet valve 64, a one-way water transport pipeline, a water pump 41, a controller 7 and an air-cooled heat dissipation component 3.

[0063] like Figure 3 As shown, the Micro LED screen 11 includes a PCB board 112 and a Micro LED component 111 ; the Micro LED component 111 is installed on the front side of the PCB board 112 .

[0064] Specifically, the PCB board 112 mainly plays the role of circuit connection and support in this system. It provides a stable electrical connection for the MicroLED component 111, so that the current can be smoothly transmitted to each Micro LED pixel to control their light emission. The Micro LED component 111 is the core part for realizing image display. It is composed of many tiny LED chips that can emit light of different colors, and various colors and images can be combined through precise control. Installing the Micro LED component 111 on the front of the PCB board 112 means that there is a close physical and electrical connection between them. The PCB board 112 provides the Micro LED component 111 with the necessary power supply and signal transmission channel, and the Micro LED component 111 realizes the image display function by emitting light after receiving the signal. As one of the main components that generate heat in this water-cooled heat dissipation system, the entire Micro LED screen 11 needs to use a specific heat dissipation method to ensure its normal operation and stable performance.

[0065] like Figure 4 As shown, the back side of the PCB board 112 facing away from the Micro LED component 111 is attached to the thermal support plate; the thermal support plate is provided with a strip-shaped cooling water channel structure 2, and the cooling water channel structure 2 includes a first interface end 157, a water channel body 21 and a second interface end 158 connected in sequence.

[0066] Specifically, by circulating the liquid in the cooling water channel structure 2 and utilizing the heat absorption and heat transfer characteristics of the liquid, the heat generated by the PCB board 112 and the Micro LED component 111 installed on the front of the PCB board 112 is quickly conducted away, thereby achieving effective heat dissipation of the Micro LED module and ensuring its stable operation and performance.

[0067] like Figure 5-Figure 7 As shown, the water inlet three-way solenoid valve 63 is a one-inlet and two-outlet three-way solenoid valve, and the water inlet three-way solenoid valve 63 has a first continuous communication end 631, a first selected communication end 632, and a second selected communication end 633;

[0068] When the water inlet three-way solenoid valve 63 is in the first state, the first continuous communication end 631 is connected to the first selected communication end 632;

[0069] When the water inlet three-way solenoid valve 63 is in the second state, the first continuous connection end 631 is connected to the second selected connection end 633. Specifically, the water inlet three-way solenoid valve 63 can switch the flow direction of the fluid by controlling its own state, thereby realizing flexible control of the coolant flow path in the water-cooling heat dissipation system based on the Micro LED module to meet different heat dissipation requirements.

[0070] The three-way reversing solenoid valve A61 is a one-in-two-out three-way solenoid valve, and has a second continuous communication end 612, a third selected communication end 611, and a fourth selected communication end 613. When the three-way reversing solenoid valve A61 is in the first state, the second continuous communication end 612 is connected to the third selected communication end 611. When the three-way reversing solenoid valve A61 is in the second state, the second continuous communication end 612 is connected to the fourth selected communication end 613.

[0071] The three-way reversing solenoid valve B62 is a one-in-two-out three-way solenoid valve, and has a third continuous communication end 621, a fifth selected communication end 622, and a sixth selected communication end 623. When the three-way reversing solenoid valve B62 is in the first state, the third continuous communication end 621 is connected to the fifth selected communication end 622. When the three-way reversing solenoid valve B62 is in the second state, the third continuous communication end 621 is connected to the sixth selected communication end 623;

[0072] The three-way water outlet valve 64 has a fourth continuous communication end 641, a seventh selected communication end 642 and an eighth selected communication end 643 which are connected to each other;

[0073] Both ends of the one-way water transport pipeline are connected to the first continuous communication end 631 and the fourth continuous communication end 641 respectively.

[0074] The first continuous communication end 631 is connected to a filter element.

[0075] like Figure 6 As shown, when the cooling water channel structure 2 transports water in the forward direction, based on the first selected communication end 632 being connected to the second continuous communication end 612, the third selected communication end 611 being connected to the first interface end 157, the second interface end 158 being connected to the third continuous communication end 621, and the fifth selected communication end 622 being connected to the seventh selected communication end 642. Under the control of the controller 7, the water flow direction at this time is: one-way water transport pipeline → filter element → first continuous communication end 631 → first selected communication end 632 → second continuous communication end 612 → third selected communication end 611 → first interface end 157 → water channel body 21 → second interface end 158 → third continuous communication end 621 → fifth selected communication end 622 → seventh selected communication end 642 → fourth continuous communication end 641 → one-way water transport pipeline.

[0076] As well as Figure 7As shown, when the cooling water channel structure 2 transports water in the reverse direction, based on the second selected communication end 633 being connected to the sixth selected communication end 623, the fourth selected communication end 613 is connected to the eighth selected communication end 643. Under the control of the controller 7, the water flow direction is: one-way water transport pipeline → filter element → first continuous communication end 631 → second selected communication end 633 → sixth selected communication end 623 → third continuous communication end 621 → second interface end 158 → water channel body 21 → first interface end 157 → third selected communication end 611 → fourth selected communication end 613 → eighth selected communication end 643 → fourth continuous communication end 641 → one-way water transport pipeline.

[0077] Obviously, no matter the cooling water channel structure 2 is transporting water in the forward direction or in the reverse direction, the water flow is: one-way water transport pipeline → filter element. In this way, the filter element can continuously realize the filtering without worry, that is, the filter residue will not be flushed into the water channel body 21 due to the reverse water transport of the reverse cooling water channel structure 2, so as to ensure the smoothness of the water channel body 21, the water inlet three-way solenoid valve 63, the reversing three-way solenoid valve A61, the reversing three-way solenoid valve B62, and the three-way water outlet valve 64.

[0078] like Figure 8 and Fig. 9 As shown, the water pump 41 is connected to a segment of the one-way water transport pipeline and is used to provide power to the one-way water transport pipeline.

[0079] Specifically, the function of the water pump 41 is to provide power to the one-way water transport pipeline, that is, to generate a pressure difference through operation to promote the flow of fluid in the pipeline. In the present application, the operation of the water pump 41 enables the coolant to circulate in the pipeline, thereby continuously taking away the heat generated by the Micro LED module to achieve effective heat dissipation of the Micro LED module.

[0080] The water inlet three-way solenoid valve 63 , the reversing three-way solenoid valve A61 , the reversing three-way solenoid valve B62 , the three-way water outlet valve 64 , and the water pump 41 are all electrically connected to the controller 7 .

[0081] like Fig.10 and 11 As shown, the air-cooled heat dissipation component 3 includes a heat dissipation fan 31 and a heat sink component 32 . The heat sink component 32 is thermally connected to a one-way water transport pipeline, and the heat dissipation fan 31 is used to cool the heat sink component 32 .

[0082] Specifically, the air-cooled heat dissipation component 3 is mainly composed of two parts: a heat dissipation fan 31 and a heat sink component 32. The heat sink component 32 has an important heat conduction function. There is a heat conduction connection between it and the one-way water transport pipeline, which means that the heat in the one-way water transport pipeline can be transferred to the heat sink component 32. The main function of the heat dissipation fan 31 is to cool the heat sink component 32 by generating airflow. After the heat sink component 32 absorbs the heat from the one-way water transport pipeline, the wind generated by the operation of the heat dissipation fan 31 can take away the heat on the heat sink component 32, thereby realizing the entire air-cooled heat dissipation process to ensure that the temperature of the system is kept within a suitable range to prevent the normal operation of the equipment from being affected by excessive temperature.

[0083] On the basis of defining the water inlet three-way solenoid valve 63 as a one-in-two-out three-way solenoid valve, the reversing three-way solenoid valve A61 as a one-in-two-out three-way solenoid valve, and the reversing three-way solenoid valve B62 as a one-in-two-out three-way solenoid valve; by defining the first selected communication end 632 to be in communication with the second continuous communication end 612, the third selected communication end 611 to be in communication with the first interface end 157, the second interface end 158 to be in communication with the third continuous communication end 621, the fifth selected communication end 622 to be in communication with the seventh selected communication end 642. And, by defining the second selected communication end 633 to be in communication with the sixth selected communication end 623, the fourth selected communication end 613 to be in communication with the eighth selected communication end 643. In this way, the cooling water channel structure 2 can be controlled by the controller 7 to carry out reverse and reverse water transport; when carrying water in the forward direction, the first interface end 157 of the cooling water channel structure 2 serves as a water inlet, and the second interface end 158 of the cooling water channel structure 2 serves as a water outlet; when carrying water in the reverse direction, the second interface end 158 of the cooling water channel structure 2 serves as a water inlet, and the first interface end 157 of the cooling water channel structure 2 serves as a water outlet. In this way, the bidirectional water transport of the cooling water channel structure 2 allows the heat-conducting support plate connected to the cooling water channel structure 2 to be uniformly cooled, and further allows the PCB board 112 connected to the heat-conducting support plate to be uniformly cooled, which is particularly suitable for the situation where the PCB board 112 is not suitable for a poor temperature difference locally. Furthermore, regardless of whether the cooling water path structure 2 transports water in the forward direction or the reverse direction, the water flow is: one-way water transport pipeline → filter element, that is, the filter element always plays a role of forward filtration, thereby reducing the maintenance frequency of the cooling water path structure 2. In particular, the cooling water path structure 2 is arranged on the heat-conducting support plate, and the heat-conducting support plate is connected to the PCB board 112. It is even more inappropriate to frequently install and disassemble the heat-conducting support plate to reduce the failure rate of the PCB board 112.

[0084] In one embodiment, the back side of the heat-conducting support plate is recessed in a direction close to the front side of the heat-conducting support plate to form a continuous receiving groove, and the water channel body 21 is a heat-conducting pipe, which is embedded in the receiving groove.

[0085] Specifically, the heat-conducting support plate has such a structure: its back side is recessed in the direction close to the front side, thereby forming a continuous receiving groove. The water channel main body 21 here adopts a heat-conducting pipe. This heat-conducting pipe can be tightly embedded in the receiving groove on the back side of the heat-conducting support plate. Such a design makes the contact between the heat-conducting pipe and the heat-conducting support plate closer, which is conducive to the rapid conduction of heat. When the system generates heat during operation, the heat can be transferred to the heat-conducting pipe embedded in the receiving groove through the heat-conducting support plate, and the cooling medium in the heat-conducting pipe can quickly take away the heat, thereby achieving effective cooling and heat dissipation, wherein the cooling medium includes water and coolant. It can be understood that the design of the heat-conducting pipe is easy to implement in terms of process and the cost is relatively low.

[0086] In one embodiment, the heat conducting pipe includes a plurality of first straight pipes 152 , a plurality of first arc-shaped pipes 153 , a second arc-shaped pipe 154 , a second straight pipe 151 , a third arc-shaped pipe 155 , and a third straight pipe 156 ;

[0087] The plurality of straight tubes are distributed in parallel and at intervals, and two adjacent first straight tubes 152 are connected through one of the arc tubes;

[0088] The second straight tube 151 is perpendicular to the first straight tube 152 and is located on the same side of the plurality of first straight tubes 152 . The third straight tube 156 is parallel to the first straight tube 152 and is located on the same side of the plurality of first straight tubes 152 .

[0089] The first interface end 157 is disposed on the first straight tube 152 closest to the third straight tube 156 among the plurality of first straight tubes 152 , and the second interface end 158 is disposed on the third straight tube 156 ;

[0090] The first straight tube 152 , the second arc tube 154 , the second straight tube 151 , the third arc tube 155 , and the third straight tube 156 , which are farthest from the third straight tube 156 among the plurality of first straight tubes 152 , are connected in sequence.

[0091] Specifically, the heat pipe is composed of a plurality of straight pipes and arc-shaped pipes of different types. The plurality of first straight pipes 152 are parallel and spaced apart, and each two adjacent first straight pipes 152 are connected by a first arc-shaped pipe 153, thus forming a group of interconnected parallel pipes. The second straight pipe 151 is perpendicular to the first straight pipe 152 and is located on the same side of the plurality of first straight pipes 152. The third straight pipe 156 is also parallel to the first straight pipe 152 and is also located on the same side of the plurality of first straight pipes 152. The first interface end 157 is arranged on the first straight pipe 152 closest to the third straight pipe 156 among the plurality of first straight pipes 152, and the second interface end 158 is arranged on the third straight pipe 156. In addition, the first straight pipe 152 farthest from the third straight pipe 156 among the plurality of first straight pipes 152 is connected to the third straight pipe 156 through the second arc-shaped pipe 154, the second straight pipe 151, and the third arc-shaped pipe 155 in sequence. Such a structural design enables the heat pipe to conduct heat in a specific shape and path, and fully conduct heat to the part to be cooled.

[0092] In one embodiment, the water channel body 21 is an internal channel formed inside the heat-conducting support plate.

[0093] Specifically, by directly setting the water channel body 21 of the cooling water channel structure 2 inside the heat-conducting support plate, the cooling water channel and the heat-conducting support plate can be closely combined, thereby greatly improving the heat conduction efficiency. At the same time, this design can save space and make the entire heat dissipation structure more compact. In addition, to a certain extent, the cooling water channel can be protected, the impact of external factors on it can be reduced, and the reliability and stability of the cooling system can be improved.

[0094] In one embodiment, see Fig.12, the internal channel includes a plurality of segment channels 22 connected end to end in sequence, and at least two segment channels 22 are arranged at intervals along the wall thickness direction of the heat-conducting support plate. In this way, the same part of the PCB board 112 can be cooled twice through at least two segment channels 22, that is, when more LED chips are locally arranged in the PCB board 112, which generates more heat, the local high temperature of the PCB board 112 is cooled multiple times through more segment channels 22, so that the temperature of each part of the PCB board 112 is more balanced, which has a unique advantage compared to air cooling. In other words, this embodiment further optimizes the layout of the heat pipe. The heat pipe is arranged crosswise multiple times in one area at different thicknesses. The purpose of such a design is to achieve more effective cooling in areas where the local heat is too high. When excessive heat occurs in a certain area on the thermal support plate, the heat pipes arranged crosswise multiple times can allow the cooling medium to flow through the area more fully, thereby improving the efficiency of heat exchange and removing the excessive local heat more quickly, ensuring that the temperature of the entire thermal support plate and PCB board 112 is maintained within a relatively reasonable range, thereby improving the performance and reliability of the entire heat dissipation system.

[0095] In one embodiment, the thermal conductive support plate includes a first thermal conductive support plate 13 and a second thermal conductive support plate 15, the back side of the PCB board 112 facing away from the Micro LED component 111 is attached to the first thermal conductive support plate 13, the second thermal conductive support plate 15 is detachably attached to the first thermal conductive support plate 13, and the cooling water channel structure 2 is arranged on the second thermal conductive support plate 15.

[0096] Specifically, in this particular structure, the thermally conductive support plate is divided into a first thermally conductive support plate 13 and a second thermally conductive support plate 15. The side of the PCB board 112 that is opposite to the Micro LED component 111 is tightly fitted on the first thermally conductive support plate 13. The second thermally conductive support plate 15 can be fitted with the first thermally conductive support plate 13 in a detachable manner. The cooling water path structure 2 is arranged on the second thermally conductive support plate 15. Such a design has many functions. On the one hand, the heat generated by the PCB board 112 during operation can be more effectively conducted away, thereby improving the heat dissipation effect. On the other hand, the detachable design of the second thermally conductive support plate 15 makes it more convenient when maintenance or replacement of the cooling water path structure 2 is required.

[0097] In one embodiment, the PCB board 112 and the first heat-conducting support plate 13 are connected via the first soft heat-conducting plate 12 .

[0098] Specifically, the first soft heat-conducting plate 12 has good thermal conductivity, and it can quickly conduct the heat generated by the PCB board 112 when it is working to the first heat-conducting support plate 13. The soft property allows it to better adapt to the uneven surface that may exist between the PCB board 112 and the first heat-conducting support plate 13, ensuring close contact, thereby improving the efficiency of heat conduction. At the same time, the soft material may also play a buffering role to a certain extent, reducing the damage to the PCB board 112 caused by external vibration and other factors.

[0099] In one embodiment, the first heat-conducting support plate 13 and the second heat-conducting support plate 15 are connected via a second soft heat-conducting plate 14 .

[0100] Specifically, the second soft heat-conducting plate 14 has good heat-conducting ability, and it can transfer heat from the first heat-conducting support plate 13 to the second heat-conducting support plate 15. Due to its soft characteristics, it can better fill the gap between the first heat-conducting support plate 13 and the second heat-conducting support plate 15, ensuring close contact between the two, thereby improving the efficiency of heat transfer. In addition, the soft material can also adapt to the relative displacement or slight deformation that may occur between the two support plates to a certain extent, play a role of buffering and protection, prevent the connection parts from being damaged due to external forces or temperature changes, and ensure the stability and reliability of the entire heat dissipation structure.

[0101] like Figure 8 and Fig. 9 As shown, in one embodiment, the water cooling system further includes a noise reduction box 42, the inner wall of the noise reduction box 42 is covered with a noise absorption layer, and the water pump 41 is arranged in the noise reduction box 42. The water tank 5 is connected to the water pump 41, the water tank 5 is located outside the noise reduction box 42, and the water tank 5 is arranged on the one-way water transport pipeline.

[0102] Specifically, the inner wall of the noise reduction box 42 is covered with a noise absorption layer. The noise absorption layer is generally made of a material with sound absorption properties, which can effectively absorb and reduce the spread of noise. The water pump 41 is placed in this noise reduction box 42. Since the water pump 41 generates a certain amount of noise during operation, placing it in the noise reduction box 42 can reduce the noise generated by the water pump 41 during operation with the help of the noise absorption layer, thereby reducing the noise generated by the entire water cooling system during operation, creating a quieter atmosphere for the use environment.

[0103] In one embodiment, the three-way water outlet valve 64 is a one-inlet and two-outlet three-way solenoid valve.

[0104] Specifically, the one-in-two-out type means that the valve has one inlet and two outlets. A three-way solenoid valve is a valve that uses electromagnetic control. The opening and closing of the valve is controlled by energizing or de-energizing the electromagnetic coil, thereby controlling the flow direction of the fluid. In this specific water-cooling heat dissipation system, the one-in-two-out three-way solenoid valve can direct the incoming coolant to different outlet channels as needed to meet the heat dissipation needs of the system under different working conditions.

[0105] The control system may be a single chip microcomputer or a control element integrated in the PCB board 112 .

[0106] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
