Description

Technical Field

[0001] This application belongs to the technical field of display devices, and more specifically, relates to a heat dissipation mechanism and a display screen. Background Art

[0002] With the rapid development of the LED industry (the full English name of LED: Light Emitting Diode, Chinese name: light emitting diode), the application scenarios of LED display screens have become more and more diverse.

[0003] The LED display screen in the related art includes a screen body and a heat dissipation mechanism. The heat dissipation mechanism is usually fixedly installed on the screen body. Although the heat dissipation mechanism can dissipate heat from the target components (such as the lamp bead group) on the screen body, it can only cover several lamp beads in the lamp bead group and cannot cover all the lamp beads in the lamp bead group. This heat dissipation method is prone to problems such as uneven heat dissipation. Utility Model Content

[0004] The purpose of the embodiments of this application is to provide a heat dissipation mechanism and a display screen, aiming to solve the technical problem of uneven heat dissipation of the target components in the related art.

[0005] To achieve the above purpose, according to one aspect of this application, a heat dissipation mechanism is provided for dissipating heat from a target component. The heat dissipation mechanism includes: a heat dissipation part for guiding air to the target component, and the heat dissipation part has multiple working postures that can respectively guide air to different positions on the target component; an adjustment part, which is drivingly connected to the heat dissipation part and can drive the heat dissipation part to switch between different working postures.

[0006] When using the heat dissipation mechanism of this application to dissipate heat from the target component, first use the heat dissipation part to guide air to the target component. After the heat dissipation part dissipates heat from the initial position on the target component for a period of time, adjust the working posture of the heat dissipation part through the adjustment part; after the adjustment is completed, the heat dissipation part can guide air to a position different from the initial position on the target component for heat dissipation treatment; after a period of time, continue to adjust the working posture of the heat dissipation part through the adjustment part, and repeat the above operation until the heat dissipation part can dissipate heat from all positions on the target component. The adjustment part in this application plays a role in adjusting the working posture of the heat dissipation part, enabling the heat dissipation part to dissipate heat from different positions on the target component, which not only helps to improve the heat dissipation uniformity and heat dissipation controllability of the target component, but also helps to shorten the time required for the target component to dissipate heat; by using the heat dissipation mechanism of this application, the target component can achieve uniform heat dissipation, which not only ensures the integrity of the target component, but also extends the service life of the target component.

[0007] Optionally, the heat dissipation part has an air inlet end and an air outlet end arranged opposite to each other. The air inlet end is used to suck in air in the direction towards the air outlet end, and the air outlet end is used to discharge air towards the target component.

[0008] The provided heat dissipation part speeds up the flow rate of the air flowing through the target component, improves the heat dissipation efficiency of the target component, and makes its heat dissipation effect more significant.

[0009] Optionally, the adjustment part includes a plurality of adjustment members. The plurality of adjustment members are arranged at intervals. Each adjustment member has an output end. The output end is connected to the heat dissipation part and can move along a preset direction. There is an adjustment angle between the direction from the air inlet end to the air outlet end and the preset direction. The adjustment angle is greater than or equal to zero and less than 90°. When the adjustment part drives the heat dissipation part to adjust to different working postures, the adjustment angle changes.

[0010] When using the heat dissipation mechanism of the present application to dissipate heat from the target component, first, the heat dissipation part is used to guide the air to the target component. After the heat dissipation part dissipates heat from the initial position on the target component for a period of time, the working posture of the heat dissipation part is adjusted so that the heat dissipation part guides the air to a position different from the initial position on the target component for heat dissipation. The specific operation is as follows: First, make the output ends of a part of the adjustment members move closer to or away from the target component along the preset direction. The number of this part of the adjustment members is greater than or equal to 1 and less than the total number of adjustment members, while the remaining adjustment members remain stationary and do not need to move along the preset direction. In this case, since only a part of the adjustment members are working, the generated torque cannot be completely balanced, resulting in the heat dissipation part tilting, and the angle of the adjustment angle also changes. The tilting direction of the heat dissipation part depends on which adjustment members are working and their acting directions. After the heat dissipation part maintains the above working posture for a period of time, continue to adjust the working posture of the heat dissipation part through the adjustment part until the heat dissipation part can dissipate heat from all positions on the target component.

[0011] Optionally, a first connection structure is provided on the output end, and a second connection structure is provided on the heat dissipation part. One of the first connection structure and the second connection structure is a connecting ball, and the other is a connecting groove for the connecting ball to be embedded and roll. The output end is connected to the heat dissipation part by the connecting ball being embedded in the connecting groove.

[0012] The connecting ball and the connecting groove used in cooperation in the present application not only play a role in connecting the adjustment member and the heat dissipation part, but also play a role in preventing interference between the adjustment member and the heat dissipation part.

[0014] Fixing and installing the connecting ball on the heat dissipation part and providing the connecting groove on the output end can not only simplify the structure of the adjusting part, making it only necessary to drive the connecting groove to move along the preset direction, but also improve the stability of the connecting ball, avoiding the loosening or falling off of the connecting ball caused by the movement of the output end. In addition, this design also improves the flexibility of the attitude adjustment of the heat dissipation part and the convenience of assembling the adjusting part and the heat dissipation part.

[0015] Optionally, the heat dissipation part is provided with an installation groove, and a partial structure of the connecting ball is fixedly embedded in the installation groove.

[0016] The provided installation groove can firmly connect the connecting ball with the heat dissipation part, avoiding the loosening or falling off of the connecting ball and ensuring the stability of the connection between the heat dissipation part and the adjusting part.

[0017] Optionally, the connecting ball has a connecting stud, the connecting stud is embedded in the installation groove, the connecting stud is provided with a first connection hole for a fastener to pass through and be fixed, the heat dissipation part is provided with a second connection hole for the fastener to pass through and be fixed, and the connecting ball is fixedly embedded in the installation groove by the fastener passing through and being fixed in the second connection hole and the first connection hole.

[0018] In this application, the fastener, the first connection hole, and the second connection hole used in cooperation can not only connect the heat dissipation part and the adjusting part, but also strengthen the connection strength and reliability between the heat dissipation part and the adjusting part. In addition, it is also beneficial to assemble and disassemble the heat dissipation part and the adjusting part. The provided connecting stud not only plays a guiding role, facilitating the smooth embedding of a partial structure of the connecting ball into the installation groove, but also serves as a support point, effectively preventing the connecting ball from loosening or falling off during operation and ensuring the reliability of the connection between the heat dissipation part and the adjusting part.

[0019] Optionally, the adjusting part is any one of an electromagnetic push rod, a cylinder, or a linear motor, and the heat dissipation part is a heat dissipation fan; and / or, a plurality of adjusting parts are arranged at intervals along the circumference of the heat dissipation part; and / or, the heat dissipation mechanism further includes an installation part, and the adjusting part is installed on the installation part; the installation part is located on the side of the air inlet end away from the air outlet end; and / or, the heat dissipation mechanism further includes an installation part, and the adjusting part is installed on the installation part; the installation part is provided with a ventilation through hole.

[0020] The above design is not only conducive to more smoothly adjusting the working attitude of the heat dissipation part and improving the adjustment efficiency, but also avoids the interference and influence of the installation part on the heat dissipation part, ensuring the normal use of the installation part. The provided ventilation through hole is not only conducive to increasing the flow rate of the air flowing through the target component, but also plays a role in blocking external dust or debris from entering the heat dissipation part.

[0021] According to another aspect of the present application, a display screen is provided, including a screen body, a target component, and the above-mentioned heat dissipation mechanism. The target component is installed on the screen body, and the heat dissipation mechanism is installed on the screen body through a connecting member. The heat dissipation part can guide air to the target component.

[0022] The adjustment part in the present application plays a role in adjusting the working posture of the heat dissipation part, enabling the heat dissipation part to dissipate heat from different positions on the target component.

By adopting the heat dissipation mechanism of the present application, the target component can achieve uniform heat dissipation, which not only ensures the integrity of the target component but also extends the service life of the target component.

[0023] Optionally, the display screen further includes a temperature detection part and a control part. The temperature detection part is used to detect the temperature of the target component. The temperature detection part is electrically connected to the control part, and the control part is electrically connected to the heat dissipation part and is also electrically connected to the adjustment part.

[0024] The temperature detection part and the control part used in combination in the present application can be linked with the heat dissipation part and the adjustment part, which is not only beneficial to improving the convenience of heat dissipation operation but also conducive to achieving uniform heat dissipation of the target component.

[0025] The beneficial effect of the heat dissipation mechanism provided by the present application is as follows: When using the heat dissipation mechanism of the present application to dissipate heat from the target component, first, the heat dissipation part guides air to the target component. After the heat dissipation part dissipates heat from the initial position on the target component for a period of time, the working posture of the heat dissipation part is adjusted by the adjustment part.

After a period of time, the working posture of the heat dissipation part is adjusted by the adjustment part again, and the above operation is repeated until the heat dissipation part can dissipate heat from all positions on the target component. The adjustment part in the present application plays a role in adjusting the working posture of the heat dissipation part, enabling the heat dissipation part to dissipate heat from different positions on the target component. This is not only beneficial to improving the heat dissipation uniformity and controllability of the target component, but also conducive to shortening the time required for the target component to dissipate heat. By adopting the heat dissipation mechanism of the present application, the target component can achieve uniform heat dissipation, which not only ensures the integrity of the target component but also extends the service life of the target component.

[0045] As recorded in the background art, with the rapid development of the LED industry (the full English name of LED: Light Emitting Diode, Chinese name: Light Emitting Diode), the application scenarios of LED displays have become more and more diverse. The LED displays in the related art include a screen body and a heat dissipation mechanism. The heat dissipation mechanism is usually fixedly installed on the screen body. Although the heat dissipation mechanism can dissipate heat from the target components (such as a lamp bead group) on the screen body, it can only cover several lamp beads in the lamp bead group and cannot cover all the lamp beads in the lamp bead group. This heat dissipation method is prone to problems such as uneven heat dissipation.

[0046] Refer toFigures 1 to 4 , to solve the above problems, according to one aspect of the present application, an embodiment of the present application provides a heat dissipation mechanism for dissipating heat from a target component 500. The heat dissipation mechanism includes a heat dissipation part 100 and an adjustment part 200. Among them, the heat dissipation part 100 is used to guide air onto the target component 500, and the heat dissipation part 100 has multiple working postures that can respectively guide air to different positions on the target component 500; the adjustment part 200 is drivingly connected to the heat dissipation part 100 and can drive the heat dissipation part 100 to switch between different working postures.

[0047] In the embodiment of the present application, the target component 500 is usually a component that needs to dissipate heat in an LED display screen, such as a lamp bead, a driving chip, a power module, and a control circuit board. In a specific embodiment, the target component 500 is any one of a lamp bead, a driving chip, a power module, and a control circuit board; the air is the air in the atmospheric environment; the working posture refers to the position and direction of the heat dissipation part 100 relative to the target component 500. The multiple working postures change continuously. In different working postures, the position or direction of the heat dissipation part 100 relative to the target component 500 changes, and the heat dissipation part 100 can guide air to different positions on the target component 500 by changing the working posture. In other embodiments, the multiple working postures can also change intermittently.

[0048] When using the heat dissipation mechanism of the present application to dissipate heat from the target component 500, first use the heat dissipation part 100 to guide air onto the target component 500. After the heat dissipation part 100 dissipates heat from the initial position on the target component 500 for a period of time, adjust the working posture of the heat dissipation part 100 through the adjustment part 200; after the adjustment is completed, the heat dissipation part 100 can guide air to a position different from the initial position on the target component 500 for heat dissipation; after a period of time, continue to adjust the working posture of the heat dissipation part 100 through the adjustment part 200, and repeat the above operation until the heat dissipation part 100 can dissipate heat from all positions on the target component 500. The adjustment part 200 in the present application plays a role in adjusting the working posture of the heat dissipation part 100, enabling the heat dissipation part 100 to dissipate heat from different positions on the target component 500, which is not only beneficial to improving the heat dissipation uniformity and controllability of the target component 500, but also beneficial to shortening the time required for the target component 500 to dissipate heat; by using the heat dissipation mechanism of the present application, the target component 500 can achieve uniform heat dissipation, which not only ensures the integrity of the target component 500, but also extends the service life of the target component 500.

[0049] Refer to Figure 2 and Figures 4 to 6, in one embodiment, the heat dissipation part 100 has an air inlet end 110 and an air outlet end 120 which are oppositely arranged. The air inlet end 110 is used to suck in air towards the direction of the air outlet end 120, and the air outlet end 120 is used to discharge air towards the target component 500.

[0050] In this embodiment, the heat dissipation part 100 is usually any one of a heat dissipation fan, a heat dissipation blower or a heat dissipation air duct. The air inlet end 110 is located on the side of the air outlet end 120 away from the target component 500. When the heat dissipation part 100 in this application needs to guide air to the target component 500, first, the air inlet end 110 sucks in air towards the direction of the air outlet end 120. Subsequently, the air outlet end 120 will discharge the air sucked in by the air inlet end 110 onto the target component 500, so that the target component 500 can be subjected to heat dissipation treatment. The provided heat dissipation part 100 speeds up the flow rate of the air flowing through the target component 500, improves the heat dissipation efficiency of the target component 500, and makes its heat dissipation effect more remarkable.

[0051] Refer to Figures 1 to 6 and Figure 8 , in one embodiment, the adjustment part 200 includes a plurality of adjustment members 210. The plurality of adjustment members 210 are arranged at intervals. The adjustment member 210 has an output end 211. The output end 211 is connected to the heat dissipation part 100, and the output end 211 can move along a preset direction; there is an adjustment angle between the direction from the air inlet end 110 to the air outlet end 120 and the preset direction. The adjustment angle is greater than or equal to zero and less than 90°; when the adjustment part 200 drives the heat dissipation part 100 to adjust to different working postures, the adjustment angle changes.

[0052] In this embodiment, the number of the adjustment members 210 is four. In other embodiments, the number of the adjustment members 210 can also be two, three or other numbers; the adjustment members 210 are located on the side of the air inlet end 110 away from the air outlet end 120. The output end 211 of the adjustment member 210 can move closer to or farther away from the target component 500 along the preset direction; in other embodiments, the adjustment members 210 can also be located on the side of the air outlet end 120 away from the air inlet end 110.

[0053] When using the heat dissipation mechanism of this application to perform heat dissipation treatment on the target component 500, first, use the heat dissipation part 100 to guide air to the target component 500. After the heat dissipation part 100 performs heat dissipation treatment on the initial position on the target component 500 for a period of time, adjust the working posture of the heat dissipation part 100, so that the heat dissipation part 100 guides air to a position different from the initial position on the target component 500 for heat dissipation treatment. The specific operation is as follows:

[0054] First, the output ends 211 of a part of the adjusting members 210 are moved closer to or away from the target component 500 along a preset direction. The number of these adjusting members 210 is greater than or equal to 1 and less than the total number of adjusting members 210. At the same time, the remaining adjusting members 210 remain stationary and do not need to move along the preset direction. In this case, since only a part of the adjusting members 210 are working, the torque generated cannot be completely balanced, which causes the heat dissipation part 100 to tilt and the angle of the adjustment angle to change. The tilt direction of the heat dissipation part 100 depends on which adjusting members 210 are working and their directions of action. After the heat dissipation part 100 maintains the above working posture for a period of time, continue to adjust the working posture of the heat dissipation part 100 through the adjusting part 200 until the heat dissipation part 100 can achieve heat dissipation treatment for all positions on the target component 500.

[0055] In other embodiments, the angle between the direction from the air intake end 110 to the air outlet end 120 and the preset direction can also be a fixed angle, and the fixed angle is 90°. At the same time, the preset direction is parallel to the radial direction of the heat dissipation part 100, so that the adjustment part 200 can drive the heat dissipation part 100 to cover the target component 500 or expose the target component 500 along the preset direction.

[0056] Reference Figures 3 to 6 as well as Figure 8 In one embodiment, a plurality of adjusting members 210 are arranged at intervals along the circumference of the heat dissipation unit 100. In this embodiment, four adjusting members 210 are arranged one-to-one corresponding to four corners of the heat dissipation unit 100; the above design is conducive to more smoothly adjusting the working posture of the heat dissipation unit 100 and improving the adjustment efficiency.

[0057] Reference Figures 3 to 9 In one embodiment, a first connecting structure is provided on the output end 211, and a second connecting structure is provided on the heat dissipation portion 100. One of the first connecting structure and the second connecting structure is a connecting ball 130, and the other is a connecting groove 212 for the connecting ball 130 to be embedded and roll. The adjusting member 210 is connected to the heat dissipation portion 100 by embedding the connecting ball 130 into the connecting groove 212.

[0058] In this embodiment, the shape of the connecting groove 212 is generally circular or elliptical, and the central angle of the connecting groove 212 is greater than 180° to prevent the connecting ball 130 from escaping from the connecting groove 212; at the same time, in order to ensure the connection strength between the adjusting member 210 and the heat dissipation part 100, the connecting ball 130 remains in contact with the groove wall of the connecting groove 212.

[0059] When the heat dissipation part 100 in this application needs to adjust its working posture, first, a part of the adjusting members 210 drives the corresponding first connection structure to approach or move away from the target component 500 along a preset direction. The number of these adjusting members 210 is greater than or equal to 1 and less than the total number of the adjusting members 210. At the same time, the remaining adjusting members 210 remain stationary and do not drive the heat dissipation part 100 to move along the preset direction; during this process, the heat dissipation part 100 will tilt. Under the dual action of the adjusting members 210 and the heat dissipation part 100, to avoid interference between the adjusting members 210 and the heat dissipation part 100, the connecting ball 130 will roll in the connecting groove 212, so that the adjustment of the working posture of the heat dissipation part 100 can be successfully completed; in this application, the cooperating connecting ball 130 and connecting groove 212 not only play a role in connecting the adjusting members 210 and the heat dissipation part 100, but also play a role in avoiding interference between the adjusting members 210 and the heat dissipation part 100.

[0060] Referring to Figures 3 to 9 , in an embodiment, the connecting ball 130 is fixedly installed on the heat dissipation part 100, the connecting groove 212 is provided on the output end 211, the connecting ball 130 is embedded in the connecting groove 212, and can roll in the connecting groove 212; the connecting groove 212 forms a first connection structure, and the connecting ball 130 forms a second connection structure.

[0061] In this embodiment, the design of fixedly installing the connecting ball 130 on the heat dissipation part 100 and providing the connecting groove 212 on the output end 211 can not only simplify the structure of the adjusting member 210, making it only need to drive the connecting groove 212 to move along the preset direction, but also improve the stability of the connecting ball 130, avoiding loosening or falling off of the connecting ball 130 due to the movement of the output end 211. In addition, this design also improves the flexibility of the posture adjustment of the heat dissipation part 100 and the convenience of assembling the adjusting member 210 and the heat dissipation part 100. In other embodiments, the connecting ball 130 can also be fixedly installed on the output end 211, the connecting groove 212 is provided on the heat dissipation part 100, the connecting ball 130 forms a first connection structure, and the connecting groove 212 forms a second connection structure.

[0062] Referring to Figures 3 to 5 and Figure 10 , in an embodiment, an installation groove 140 is provided on the heat dissipation part 100, and a part of the structure of the connecting ball 130 is fixedly embedded in the installation groove 140.

[0063] In the present embodiment, the shape of the installation groove 140 is generally circular or elliptical. The connecting ball 130 is usually in close contact with the groove wall of the installation groove 140, and the connecting ball 130 is usually fixedly embedded in the installation groove 140 by means of screws or interference fit. The provided installation groove 140 enables the connecting ball 130 to be firmly connected to the heat dissipation part 100, avoiding loosening or falling off of the connecting ball 130, and ensuring the stability of the connection between the heat dissipation part 100 and the adjusting part 210.

[0064] Referring to Figures 6 to 10 , in an embodiment, the connecting ball 130 has a connecting convex post 131. The connecting convex post 131 is embedded in the installation groove 140. A first connection hole 1311 for a fastener to pass through and be fixed is provided on the connecting convex post 131, and a second connection hole 150 for a fastener to pass through and be fixed is provided on the heat dissipation part 100. The connecting ball 130 is fixedly embedded in the installation groove 140 by the fastener passing through and being fixed in the second connection hole 150 and the first connection hole 1311.

[0065] In the present embodiment, the connecting convex post 131 is a part of the connecting ball 130, and the connecting convex post 131 and the connecting ball 130 are an integral part; the fastener is a fastening screw, both the first connection hole 1311 and the second connection hole 150 are screw holes, and the first connection hole 1311 and the second connection hole 150 communicate; the fastener, the first connection hole 1311 and the second connection hole 150 used in cooperation in the present application can not only connect the heat dissipation part 100 and the adjusting part 210, but also enhance the connection strength and connection reliability between the heat dissipation part 100 and the adjusting part 210. In addition, it is beneficial to assemble and disassemble the heat dissipation part 100 and the adjusting part 210. The provided connecting convex post 131 not only plays a guiding role, facilitating the smooth embedding of a part of the structure of the connecting ball 130 into the installation groove 140, but also serves as a support point, effectively avoiding loosening or falling off of the connecting ball 130 during operation, and ensuring the reliability of the connection between the heat dissipation part 100 and the adjusting part 210.

[0066] Referring to Figures 1 to 10 , in an embodiment, the adjusting part 210 is any one of an electromagnetic push rod, a cylinder or a linear motor, and the heat dissipation part 100 is a heat dissipation fan. In the present embodiment, the length direction of the adjusting part 210 is parallel to the preset direction. When the adjusting part 210 is an electromagnetic push rod, the piston rod on the electromagnetic push rod forms the output end 211 of the adjusting part 210; when the adjusting part 210 is a cylinder, the piston rod on the cylinder forms the output end 211 of the adjusting part 210; when the adjusting part 210 is a linear motor, the slide table of the linear motor forms the output end 211 of the adjusting part 210.

[0070] Referring to Figures 1 to 10 , according to another aspect of the present application, an embodiment of the present application further provides a display screen, which includes a screen body 400, a target component 500, and the above heat dissipation mechanism. The target component 500 is mounted on the screen body 400, and the heat dissipation mechanism is mounted on the screen body 400 through a connecting member 600. The heat dissipation portion 100 can guide air to the target component 500.

[0071] In this embodiment, the display screen is usually an LED display screen, and the target component 500 is usually a component that needs to be heat-dissipated in the LED display screen, such as a lamp bead, a driving chip, a power module, and a control circuit board. In a specific embodiment, the target component 500 is any one of a lamp bead, a driving chip, a power module, and a control circuit board; the mounting portion 300 is located on the side of the heat dissipation portion 100 away from the target component 500; the connecting member 600 is usually a connecting bar, the first end of the connecting member 600 is fixedly mounted on the screen body 400 through a connecting screw, and the second end of the connecting member 600 is fixedly mounted on the mounting portion 300 through a connecting screw; to enhance the mounting strength of the heat dissipation mechanism on the screen body 400, the number of connecting members 600 is multiple, and the multiple connecting members 600 are arranged at intervals along the circumference of the mounting portion 300. In addition, the number of target components 500 is multiple. To facilitate heat dissipation of the multiple target components 500 simultaneously, the number of heat dissipation mechanisms is multiple, and the multiple heat dissipation mechanisms are respectively arranged in one-to-one correspondence with the multiple target components 500.

[0072] Referring to Figure 1 andFigure 2 In one embodiment, the display screen further includes a temperature detection unit 700 and a control unit 800. The temperature detection unit 700 is configured to detect the temperature of the target component 500. The temperature detection unit 700 is electrically connected to the control unit 800, and the control unit 800 is electrically connected to the heat dissipation unit 100 and is also electrically connected to the adjustment unit 200.

[0073] In this embodiment, the temperature detection unit 700 is a temperature sensing module. The temperature sensing module is installed on the target component 500 and is used to monitor the temperature of the target component 500 in real time; the control unit 800 is a control circuit board. When heat dissipation is required for the target component 500 in this application, first, the temperature detection unit 700 feeds back the detected temperature information to the control unit 800. The control unit 800 converts the temperature information into an electrical signal and respectively feeds it back to the heat dissipation unit 100 and the adjustment unit 200, so that the adjustment unit 200 adjusts the working posture of the heat dissipation unit 100, thereby enabling the target component 500 to achieve uniform heat dissipation. The temperature detection unit 700 and the control unit 800 used in cooperation in this application can be linked with the heat dissipation unit 100 and the adjustment unit 200, which is not only beneficial to improving the convenience of heat dissipation operation but also beneficial to enabling the target component 500 to achieve uniform heat dissipation.

[0074] In summary, implementing the heat dissipation mechanism and the display screen provided in this embodiment has at least the following beneficial technical effects: When using the heat dissipation mechanism of this application to dissipate heat from the target component 500, first, the heat dissipation unit 100 guides air to the target component 500. After the heat dissipation unit 100 dissipates heat from the initial position on the target component 500 for a period of time, the adjustment unit 200 adjusts the working posture of the heat dissipation unit 100; after the adjustment is completed, the heat dissipation unit 100 can guide air to a position different from the initial position on the target component 500 for heat dissipation treatment; after a period of time, the adjustment unit 200 continues to adjust the working posture of the heat dissipation unit 100, and the above operation is repeated until the heat dissipation unit 100 can dissipate heat from all positions on the target component 500. The adjustment unit 200 in this application plays a role in adjusting the working posture of the heat dissipation unit 100, enabling the heat dissipation unit 100 to dissipate heat from different positions on the target component 500, which is not only beneficial to improving the heat dissipation uniformity and heat dissipation controllability of the target component 500 but also beneficial to shortening the time required for the target component 500 to dissipate heat; by adopting the heat dissipation mechanism of this application, the target component 500 can achieve uniform heat dissipation, which not only ensures the integrity of the target component 500 but also extends the service life of the target component 500.
