Description

Technical Field

[0001] This utility model relates to the field of display device technology, and specifically to a heat dissipation structure and display device for a display screen. Background Technology

[0002] In recent years, with the development of urban construction, the demand for light pole screens has been increasing. To meet the functional requirements of urban beautification and information display, light pole screens are developing towards thinner, lighter, larger, and smaller pitch. This trend has led to a more compact internal structure and increased power. However, light pole screens operate outdoors year-round and are significantly affected by the external environment. In addition, to meet waterproofing requirements, the internal space of the screen is small and highly sealed. Due to the high brightness and high power of light pole screens, the heat generation is also quite high, which increases the failure rate of components.

[0003] Currently, the common heat dissipation solution for light pole screens is to use fans to draw hot air from inside the screen to the outside. Due to space and wiring limitations, the main heat-generating components such as the power board and motherboard are usually located in the middle of the screen, while the ventilation holes are located at the bottom and sides. The fans are installed close to the exhaust vents on the side frame. Because the power board and other heat-generating components are far from the fans, most of the cooling air is drawn directly to the outside of the screen without passing over these components, resulting in excessively high local temperatures inside the screen and poor heat dissipation. Simply increasing the number of fans cannot effectively solve the heat dissipation problem. Traditional heat dissipation methods are no longer sufficient to meet the current heat dissipation requirements of light pole screens. This utility model proposes a new solution to address the above problems. Utility Model Content

[0004] To overcome at least one of the aforementioned drawbacks, this utility model provides a heat dissipation structure and a display device for a display screen. The objective of this utility model can be achieved by employing the following technical solution:

[0005] A first aspect of this application provides a heat dissipation structure for a display screen, applied to a display device. The display device includes a housing, a heat-generating element is disposed within the housing, and an air inlet and an exhaust outlet are provided on the housing. The heat dissipation structure for the display screen includes a heat dissipation assembly, which includes:

[0006] A gas transmission pipeline, the gas transmission pipeline includes an inlet end and an outlet end, the inlet end extends toward the heating element, the heating element is located between the inlet hole and the inlet end, and the outlet end is connected to the exhaust hole;

[0007] A fan is installed inside the air supply pipe to drive external air into the housing through the air inlet, which then flows through the heating element and into the air supply pipe before being discharged through the exhaust port.

[0008] In one possible implementation, the gas pipeline includes:

[0009] An air intake pipe is provided with several vent holes, which are arranged corresponding to the heating element area.

[0010] An exhaust pipe, one end of which is connected to the intake pipe and the other end of which is connected to the exhaust port, allows the airflow passing through the heating element to pass through the intake pipe and the exhaust pipe in sequence.

[0011] In one possible implementation, a plurality of the vent holes are arranged in a matrix along the vertical direction, and the total width of the matrix in the horizontal direction is not less than the width of the heating element area, so that the airflow covers the heating element.

[0012] In one possible implementation, the air inlet is located at the bottom of the housing, the exhaust outlet is located on the side of the housing, the air supply pipe has a bent structure, the air inlet pipe is horizontally arranged, and the exhaust pipe extends obliquely downward from the air inlet pipe to the exhaust outlet.

[0013] In one possible implementation, the gas pipeline further includes:

[0014] The air intake pipe includes a chamber for housing the fan, and the cover plate is used to cover the chamber.

[0015] In one possible implementation, the intake pipe includes:

[0016] A partition divides the chamber into a first chamber and a second chamber. The first chamber is connected to the air inlet pipe, and the second chamber is connected to the exhaust pipe. The partition is provided with a guide hole that matches the air inlet of the fan.

[0017] In one possible implementation, the heat dissipation component further includes:

[0018] A sealing gasket is disposed between the fan and the partition to form a seal.

[0019] A second aspect of this application provides a display device, including a heat dissipation structure for a display screen according to any of the types described in the first aspect; and...

[0020] Box;

[0021] A heating element is located inside the housing and corresponds to the air inlet of the gas pipeline.

[0022] In one possible implementation, the housing includes a front frame assembly, a rear frame assembly, and a side frame, wherein the rear frame assembly is movably connected to the side frame via a hinge.

[0023] The front frame assembly includes a display module and a module fixing plate. The module fixing plate is provided with horizontal reinforcing ribs and vertical reinforcing ribs. The heating element is connected to the module fixing plate by studs.

[0024] In one possible implementation, the housing includes at least two heat dissipation components and exhaust vents corresponding to each heat dissipation component. The heat dissipation components and the corresponding exhaust vents are respectively located at different heat-generating elements, so that the heat from each heat-generating element is discharged through an independent airflow channel.

[0025] The beneficial technical effects of this utility model are as follows: According to the present disclosure, the heat dissipation structure and display device for the display screen include an air supply pipe and a fan.

Moreover, the hot and cold airflow paths are separated, which greatly reduces heat exchange interference, optimizes the airflow path, and extends the service life of the equipment.

[0039] In the following detailed disclosure, these embodiments are fully described with reference to the accompanying drawings. In order to enable those skilled in the art to understand and clarify the technical solution of this utility model more clearly, the embodiments described below are not limited thereto. The present utility model will be further described in detail below with reference to the embodiments and the accompanying drawings.

The terms "install," "connect," "join," and "fix" should be interpreted broadly.

[0041] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] The first aspect of this application, as Figures 1-8As shown, a heat dissipation structure for a display screen is provided, which is applied to a display device. The display device includes a cabinet 1, and a heating element 2 is provided inside the cabinet 1. An air inlet 15 and an exhaust 16 are provided on the cabinet 1. The heat dissipation structure for the display screen includes a heat dissipation component 3, which includes an air supply pipe 31 and a fan 32. The air supply pipe 31 includes an air inlet end and an air outlet end. The air inlet end extends toward the heating element 2. The heating element 2 is located between the air inlet 15 and the air inlet end. The air outlet end is connected to the exhaust 16. The fan 32 is provided inside the air supply pipe 31 and is used to drive the external air of the cabinet 1 to enter from the air inlet 15, flow through the heating element 2, and then enter the air supply pipe 31 and be discharged from the exhaust 16.

[0043] The heat dissipation structure for the display screen provided in this embodiment extends the air inlet of the air supply pipe 31 toward the heating element 2. The fan 32 drives the external air of the housing 1 to enter through the air inlet 15, flow through the heating element 2, and then enter the air supply pipe 31 and exit through the exhaust port 16. The heat dissipation component 3 and the heating element 2 are positioned one-to-one. Combined with the partition design of independent airflow channels, the cold air is precisely directed to the specific heating area where the heating element 2 is located, forming a directional airflow path that blows directly to the heat source. After the cold air flows through the heating element 2, it quickly absorbs heat and is then introduced into the air supply pipe 31 and efficiently discharged from the exhaust port 16. This eliminates the secondary heating problem caused by the backflow of hot air in traditional open heat dissipation systems, avoids the attenuation of heat dissipation efficiency caused by the mixing of hot and cold airflows, significantly improves the heat exchange rate, greatly improves heat dissipation efficiency, and extends the service life of the equipment.

[0044] The heat dissipation structure for the display screen provided in this embodiment achieves physical isolation of zoned heat dissipation by corresponding the positions of the heat dissipation component 3 and the heat-generating element 2 one by one, and each heat-generating element 2 is configured with an independent airflow channel, namely the airflow path of air inlet 15 → heat-generating element 2 → air supply pipe 31 → exhaust port 16. This can effectively prevent heat cross-interference between different heat-generating areas, and is especially suitable for multi-heat source scenarios, ensuring that all components in the cabinet 1 are in a good heat dissipation environment.

[0045] The heat dissipation structure for the display screen provided in this embodiment forms a closed airflow channel with the inside of the housing 1 through the air supply pipe 31. External dust and rainwater cannot enter the inside of the housing 1 through the heat dissipation path. The directional exhaust design keeps hot air away from sensitive electronic components and prevents high-temperature gas from spreading inside the housing 1, ensuring stable operation of the equipment in harsh environments such as humid and dusty conditions.

[0046] Understandably, the heat dissipation structure for displays provided in this embodiment systematically solves the technical problems of turbulent airflow, severe heat accumulation, and high risk of environmental corrosion in traditional display heat dissipation through directional airflow guidance, zoned heat dissipation, and separation of hot and cold paths. It is especially suitable for outdoor display scenarios with high power and multiple heat sources, improving heat dissipation efficiency, equipment reliability, and environmental adaptability.

[0047] In one possible implementation, such as Figures 1-8 As shown, the gas supply pipe 31 includes an inlet pipe 311 and an exhaust pipe 312. The inlet pipe 311 has several vent holes 3111, which are corresponding to the area of ​​the heating element 2. One end of the exhaust pipe 312 is connected to the inlet pipe 311, and the other end of the exhaust pipe 312 is connected to the exhaust port 16. The airflow passing through the heating element 2 passes through the inlet pipe 311 and the exhaust pipe 312 in sequence.

[0048] Among them, the ventilation holes 3111 on the air intake pipe 311 directly correspond to the area of ​​the heating element 2. The fan 32 drives the cold air outside the housing 1 to enter the housing 1 through the air intake hole 15 and flow towards the ventilation hole 3111. The cold air evenly covers the surface of the heating element 2, ensuring that the key components in the heating area are given priority to be flushed by the cold air, avoiding local overheating, significantly improving the heat dissipation efficiency, and ensuring the service life of the key components.

[0049] In this process, after the airflow passes through the heating element 2, it immediately enters the intake pipe 311 through the vent 3111 and is discharged from the exhaust port 16 through the exhaust pipe 312. After absorbing heat, the cold air directly enters the closed air supply pipe 31, avoiding mixing with the cold air that has not participated in heat exchange, reducing ineffective heat circulation, and improving the airflow heat dissipation capacity.

[0050] It is understandable that, such as Figure 3 and Figure 4 As shown, the intake pipe 311 and the exhaust pipe 312 can be designed as separate units. By adjusting the length of the intake pipe 311, the position of the vent 3111, the length of the exhaust pipe 312 and the bending angle, different sizes of housing 1 or different power of heating elements 2 can be flexibly matched.

[0051] Among them, such as Figure 5 As shown, the intake pipe 311 is provided with several first mounting holes 3114. The intake pipe 311 is connected to the module fixing plate 112 of the housing 1 by screwing into the first mounting holes 3114 with bolts. One end of the intake pipe 311 is provided with a second mounting hole 3115, and one end of the exhaust pipe 312 is provided with a third mounting hole 3116 corresponding to the second mounting hole 3115. The intake pipe 311 is connected to the exhaust pipe 312 by screwing into the second mounting hole 3115 and the third mounting hole 3116 with bolts.

[0052] In one possible implementation, such as Figure 5 , Figure 6 and Figure 8 As shown, several vents 3111 are distributed in a matrix along the vertical direction, and the total width of the matrix in the horizontal direction is adapted to the width of the heating element 2 area so that the airflow covers the heating element 2.

[0053] Among them, such as Figure 1 and Figure 2 As shown, several vent holes 3111 are arranged facing the air inlet 15, and the heating element 2 is located between the air inlet 15 and the vent holes 3111. The vent holes 3111 can be arranged in multiple rows and columns along the vertical direction to form a dense matrix similar to the width of the area of ​​the heating element 2. Cold air diffuses to the surface of the heating element 2, which is especially suitable for the three-dimensional heat dissipation requirements of high-power heating element 2.

[0054] Understandably, the total horizontal width of the matrix-type vent 3111 matches the area of ​​the heating element 2, so that the airflow coverage area almost coincides with the boundary of the element, avoiding cold air overflowing into non-heating areas or heat dissipation blind spots caused by insufficient airflow coverage, improving the utilization rate of cold air, reducing the energy consumption of the fan 32, and preventing disordered airflow diffusion from interfering with other components in the cabinet 1.

[0055] In one possible implementation, such as Figure 1 and Figure 2 As shown, the air intake 15 is located at the bottom of the housing 1, and the exhaust 16 is located on the side of the housing 1. Figures 3-8 As shown, the gas transmission pipe 31 has a bent structure, the air inlet pipe 311 is set horizontally, and the exhaust pipe 312 extends downward from the air inlet pipe 311 to the exhaust port 16.

[0056] Among them, such as Figure 2 As shown, the air inlet 15 is located at the bottom of the housing 1. A filter layer can be provided on the air inlet 15 to isolate impurities and dust outside the housing 1, preventing impurities from entering the housing 1 and affecting the components. The air inlet 15 at the bottom allows naturally sinking cold air to enter the housing 1. The exhaust port 16 is located on the side of the housing 1. Cold air is drawn into the housing 1 from the bottom and evenly diffused to the heating element 2 before entering the horizontal air inlet pipe 311. The heated air is directed to the side for exhaust through the downward-sloping exhaust pipe 312.

[0057] The downward-sloping exhaust pipe 312 forms a natural flow guide slope, allowing condensate or rainwater that has accidentally seeped into the pipe to flow downwards along the pipe wall and be directly discharged outside the housing 1 through the side exhaust port 16, preventing liquid from stagnating or flowing back into the air intake pipe 311. The airflow continuously blown outwards by the fan 32 forms a dynamic wind pressure barrier outside the exhaust port 16, which can effectively block liquids such as rainwater and fog. Combined with the downward tilt angle of the exhaust pipe 312, external liquids cannot enter the interior of the housing 1 under the combined action of gravity and wind pressure, ensuring that the interior of the display screen remains dry.

[0058] In one possible implementation, such as Figures 3-6 As shown, the gas pipeline 31 also includes a cover plate 313, and the air inlet pipe 311 includes a chamber for accommodating the fan 32, with the cover plate 313 used to cover the chamber.

[0059] Among them, such as Figure 5 As shown, the intake pipe 311 can be an L-shaped structure, with the front end being the intake end, the middle chamber being the mounting position for the fan 32, and the rear end being used for air outlet and connection to the exhaust pipe 312.

[0060] The cover plate 313 is designed to be detachable, which enables the fan 32 to be installed and replaced quickly. The cover plate 313 and the air intake pipe 311 form a chamber, which can effectively protect the fan 32.

[0061] Among them, the fan 32 includes an axial fan 32, which has high heat dissipation efficiency. It drives the airflow by generating centrifugal force through the rotation of the fan blades. It has air intake on the front and air exhaust on the side. The fan 32 is installed inside the cavity and can be tightly installed after the cover plate 313 is locked.

[0062] In one possible implementation, such as Figure 5 and Figure 6 As shown, the intake pipe 311 includes a partition 3112, which divides the chamber into a first chamber and a second chamber. The first chamber is connected to the intake pipe 311, and the second chamber is connected to the exhaust pipe 312. The partition 3112 is provided with a guide hole 3113 that matches the air inlet of the fan 32.

[0063] The partition 3112 divides the chamber into a first chamber and a second chamber. The first chamber and the second chamber after being separated by the partition 3112 correspond to independent flow channels for air intake and exhaust, respectively, balancing the pressure difference before and after the fan 32, preventing airflow fluctuations caused by excessive negative pressure or back pressure, and ensuring the stability of system operation.

[0064] Among them, the guide hole 3113 on the partition 3112 matches the air inlet of the fan 32, guiding the airflow to pass smoothly and accelerate through the rotating surface of the fan 32 impeller, reducing airflow bypass or local eddies, maximizing the use of the fan 32's power, reducing ineffective energy consumption, reducing the fan 32's power loss, and extending the motor's life.

[0065] In one possible implementation, such as Figure 3 and Figure 4 As shown, the heat dissipation assembly 3 also includes a sealing gasket 33, which is disposed between the fan 32 and the partition 3112 to form a seal.

[0066] Among them, a sealing gasket 33 is provided at the joint surface between the fan 32 and the partition 3112. The sealing gasket 33 includes a sealing ring or a waterproof strip to form a closed space, which can reduce airflow leakage and ensure that cold air can fully enter the fan 32 from the guide hole 3113, avoiding the loss of heat dissipation efficiency caused by ineffective circulation.

[0067] The second aspect of this application, as Figures 1-8As shown, a display device is provided, including a heat dissipation structure for a display screen according to any of the first aspects, a housing 1, and a heating element 2, wherein the heating element 2 is located inside the housing 1 and corresponds to the vent position of the air supply pipe 31.

[0068] The display device provided in this embodiment directly matches the heat source with the heat dissipation path and actively guides the airflow. The position of the heating element 2 corresponds to the air inlet of the air supply pipe 31, ensuring that the cold airflow flows directly over the surface of the heating element 2 after passing through the heat dissipation structure, avoiding heat diffusion within the housing 1 and reducing ineffective heat dissipation areas. The air inlet of the air supply pipe 31 and the heating element 2 form a direct or surrounding airflow distribution, forcing the airflow to cover the core area of ​​the heating element 2, avoiding local overheating that could lead to performance degradation or component damage. This achieves a comprehensive improvement in the heat dissipation efficiency, space utilization, and reliability of the display device. It is especially suitable for fields with concentrated heat loads and heat dissipation sensitivity, such as light pole screens and ultra-thin electronic billboards, taking into account both high-efficiency heat dissipation and equipment miniaturization requirements, and ensuring the long-term stable operation of high-density electronic equipment.

[0069] In one possible implementation, such as Figure 1 and Figure 2 As shown, the housing 1 includes a front frame assembly 11, a rear frame assembly 12, and a side frame 14. The rear frame assembly 12 is movably connected to the side frame 14 via a hinge 13.

[0070] The rear frame assembly 12 can be connected to the side frame 14 via hinge 13, supporting multiple opening methods such as side opening, top opening, or front flip, adapting to different installation scenarios and improving operational convenience. The hinge 13 connection allows the rear frame assembly 12 to be fully extended to more than 180°, fully exposing the internal space of the housing 1, facilitating batch replacement of components, cleaning or inspection of cables, and reducing the risk of blind spot operation.

[0071] The front frame assembly 11 is relatively thick, and the internal components are fixed on the front frame assembly 11. The frame of the front frame assembly 11 can be welded from aluminum alloy profiles into a frame structure, and the display module fixing plate 112 is fixed on the front frame assembly 11.

[0072] Among them, such as Figure 8 As shown, the side frame 14 can be a two-layer structure. The heat dissipation component 3 is installed on the side frame 14, and the exhaust hole 16 is opened on the outer wall of the side frame 14. The exhaust end of the air supply channel is closely attached to the inner wall of the outer layer of the profile. Due to the two-layer structure of the side frame 14, water that seeps in from the gap can only flow to the outer layer of the side frame 14 and then flow out from the bottom air inlet 15 or water leakage hole, and cannot enter the display screen, thus having excellent waterproof effect.

[0073] Among them, such as Figure 7 and Figure 8As shown, a fixing plate is provided on the exhaust pipe 312. The fixing plate is installed against the inner wall of the side frame 14 to fix the exhaust pipe 312 on the side frame 14, ensuring that the exhaust end of the exhaust pipe 312 is aligned with the exhaust hole 16 on the side of the box body 1, avoiding turbulence or backflow of airflow due to angular deviation, and improving exhaust efficiency.

[0074] In one possible implementation, such as Figure 2 As shown, the front frame assembly 11 includes a display module 111 and a module fixing plate 112. The module fixing plate 112 is provided with a horizontal reinforcing rib 1122 and a vertical reinforcing rib 1121. The heating element 2 is connected to the module fixing plate 112 by a stud 1123.

[0075] Among them, the horizontal reinforcing ribs 1122 and the vertical reinforcing ribs 1121 are cross-connected to form a mesh support structure, which evenly distributes the load and external stress of the display module 111, significantly improves the bending and deformation resistance of the module fixing plate 112, avoids the screen splicing gap from being misaligned due to substrate deformation, and ensures the flatness of the display surface.

[0076] The standardized screw hole layout on the front of the module mounting plate 112 supports the rapid positioning and installation of multi-size display modules 111, adapting to screen expansion, replacement, or repair needs, and reducing the complexity and time cost of manual adjustment. The heat-generating components 2 mainly include the module power supply 21 and the motherboard 22. The module power supply 21, motherboard 22, and air intake pipe 311 are mounted on the back of the module mounting plate 112 by studs 1123, realizing physical isolation between the electrical module, heat dissipation system, and display module 111, avoiding electromagnetic interference or heat accumulation.

[0077] In one possible implementation, such as Figure 1 and Figure 2 As shown, the housing 1 includes at least two heat dissipation components 3 and exhaust holes 16 corresponding to each heat dissipation component 3. The heat dissipation components 3 and the corresponding exhaust holes 16 correspond one-to-one with the positions of different heat-generating elements 2, so that the heat of each heat-generating element 2 can be discharged through independent airflow channels.

[0078] Each heat-generating element 2 has a corresponding dedicated heat dissipation component 3 and exhaust vent 16, forming an independent airflow circulation path. This avoids the mixing and superposition of heat from different heat sources, prevents heat from high-temperature areas from spreading to low-temperature components, and ensures the heat dissipation priority of key components, such as the motherboard 22 and the module motor. The independent airflow channel directly covers the surface of the high-heat-generating element 2, and quickly conducts heat out of the housing 1 through a short path, reducing the ambient temperature around the component and avoiding the problem of local heat accumulation caused by airflow detours in the traditional centralized heat dissipation mode.

[0079] When a single heat dissipation component 3 fails or requires maintenance, it can be disassembled and maintained independently. Other heat dissipation components 3 still provide a certain heat dissipation function without interrupting the operation of other heat-generating components 2 or disassembling the overall structure of the housing 1.
