Description

Technical Field

[0001] The present invention relates to the technical field of display devices and relates to a display device. Background Art

[0002] Network information security teaching experiment devices have gradually become an indispensable tool in teaching activities. Most traditional network information security teaching experiment devices adopt a single air-cooling heat dissipation method, that is, a cooling fan is directly installed on the outer shell of the experiment device, and the temperature of the display screen is reduced through air convection. Although this heat dissipation method can reduce the heat generated by the display screen to a certain extent, when conducting high-load teaching demonstrations or experiments for a long time, the heat dissipation effect of air cooling is often not ideal. The display screen will continuously generate a large amount of heat during continuous operation, and air cooling may not be able to effectively export this part of the heat in time, resulting in too high a temperature of the display screen. This will not only reduce the working efficiency and response speed of the display screen, but may also cause problems such as color distortion and brightness decline of the display screen, seriously affecting the quality and experience of network information security teaching. Summary of the Invention

[0003] The main purpose of the present invention is to provide a display device to solve the problem of low heat dissipation efficiency of the display screen of the existing network information security teaching experiment device.

The coolant flow pipe is in contact with the display screen, and both ends of the coolant flow pipe are respectively communicated with the first liquid container and the second liquid container, so that the coolant in the first liquid container flows through the coolant flow pipe and enters the second liquid container.

[0005] Further, the display device further includes a maintenance board, which is arranged on the side of the frame body away from the display screen. The maintenance board and the frame body form an accommodation cavity. A plurality of heat dissipation holes are uniformly penetrated through the maintenance board, and the heat dissipation holes are communicated with the accommodation cavity. The cooling fan is located in the accommodation cavity, and the frame body and the maintenance board are detachably connected.

[0006] Further, the liquid cooling component further includes a pump body, a first water suction pipe, and a second water suction pipe. The pump body is communicated with the inner cavity of the first liquid container through the first water suction pipe, and the pump body is also communicated with the coolant flow pipe through the second water suction pipe, so that the pump body pumps the coolant in the first liquid container into the coolant flow pipe.

[0007] Further, a slot is provided on the frame body, and a liquid injection port is provided on the second liquid container. The liquid injection port is communicated with the inner cavity of the second liquid container; the liquid cooling component further includes a third water suction pipe, and the third water suction pipe passes through the slot to be communicated with the liquid injection port.

[0008] Further, a connecting pipe is provided between the second liquid container and the first liquid container, so that the coolant in the second liquid container flows back to the first liquid container through the connecting pipe.

[0009] Further, two writing boards and two lighting members are provided on the frame body. The two writing boards are respectively arranged on both sides of the display screen. The two lighting members are arranged in one-to-one correspondence with the two writing boards, and each lighting member is arranged above the corresponding writing board.

[0010] Further, the display device further includes a support platform. The upper surface of the support platform is provided with a frame body. Among them, two fixing rods are provided on the lower surface of the support platform, and a placement board is arranged between the two fixing rods. The placement board is used for placing a control member; and / or, a support rod extending in the vertical direction is further provided on the lower surface of the support platform, and a moving wheel is arranged at the bottom of the support rod.

[0011] Further, a first fixing frame is provided on the support platform. The first fixing frame is located below the maintenance board.

Among them, the operating member is communicatively connected to the display screen.

[0012] Further, a second fixing frame is provided on the support platform. The second fixing frame is located below the display screen. The top of the second fixing frame is provided with a second placement opening for an input member to pass through and enter the second fixing frame.

By arranging the heat dissipation fan facing the display screen, the heat dissipation fan can directly perform air cooling on the display screen, accelerating the heat dissipation on the surface of the display screen. At the same time, by closely attaching the coolant flow pipe to the back of the display screen, the coolant in the first liquid container flows through the coolant flow pipe and enters the second liquid container, so that the coolant directly absorbs the heat generated by the display screen in the working state when flowing through the coolant flow pipe. The cooling effect of the liquid cooling component is usually better than that of air cooling because it utilizes the high heat capacity and thermal conductivity of the coolant and can more effectively take away a large amount of heat. The dual cooling mechanism of the heat dissipation fan and the liquid cooling component makes the heat dissipation of the display screen faster and more uniform, improving the heat dissipation efficiency of the display screen and solving the problem of low heat dissipation efficiency of the display screen of the network information security teaching experiment device in the prior art.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, further discussion thereof is not required in subsequent drawings.

[0025] In the description of the present application, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom", etc. are generally based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Without contrary instructions, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus cannot be construed as limiting the protection scope of the present application; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0026] Please refer to Figures 1 to 5 , the present invention provides a display device, including: a frame 1, on which a display screen 2 is provided; a cooling fan 3, which is arranged inside the frame 1 and is oriented towards the display screen 2; a liquid cooling component, which is arranged inside the frame 1, and the liquid cooling component includes: a coolant flow pipe 4, a first liquid container 5, and a second liquid container 6. The coolant flow pipe 4 is in contact with the display screen 2, and both ends of the coolant flow pipe 4 are respectively communicated with the first liquid container 5 and the second liquid container 6, so that the coolant in the first liquid container 5 flows through the coolant flow pipe 4 and enters the second liquid container 6.

[0027] The display device of the present invention includes: a housing 1, a cooling fan 3, and a liquid cooling component. A display screen 2 is provided on the housing 1. The liquid cooling component includes a coolant flow pipe 4, a first liquid container 5, and a second liquid container 6. The cooling fan 3 is arranged facing the display screen 2, so that the cooling fan can directly perform air cooling on the display screen 2 to accelerate the heat dissipation from the surface of the display screen 2. At the same time, the coolant flow pipe 4 is closely attached to the back of the display screen 2, and the coolant in the first liquid container 5 flows through the coolant flow pipe 4 into the second liquid container 6, so that the coolant directly absorbs the heat generated by the display screen 2 during operation when flowing through the coolant flow pipe 4. The cooling effect of the liquid cooling component is usually better than that of air cooling because it utilizes the high heat capacity and thermal conductivity of the coolant and can more effectively take away a large amount of heat. The dual cooling mechanism of the cooling fan 3 and the liquid cooling component makes the display screen 2 dissipate heat more quickly and evenly, improves the heat dissipation efficiency of the display screen, and solves the problem of low heat dissipation efficiency of the display screen of the network information security teaching experiment device in the prior art.

[0028] Specifically, the coolant flow pipe 4 is arranged in an "S" shape on the rear end face of the display screen 2. Compared with a straight line or other relatively simple shapes, it can significantly increase the contact area with the rear end face of the display screen 2. This design can ensure more sufficient heat contact between the coolant and the heat-generating area of the display screen, improve the heat exchange efficiency, and thus more effectively absorb and take away the heat generated when the display screen 2 is working. The flow path of the coolant in the "S" - shaped pipe is longer and has multiple curvature changes. This design helps to optimize the hydrodynamic performance, that is, by increasing the flow path of the fluid and changing the flow direction, the turbulence degree of the coolant can be increased, further improving the heat exchange efficiency. Turbulence can improve the contact efficiency between the fluid and the pipe wall, enabling heat to be transferred to the coolant more quickly, and thus dissipating heat more efficiently. The "S" - shaped layout of the coolant flow pipe 4 can ensure more uniform heat absorption on the rear end face of the display screen 2. Different from the single - straight - line or point - contact cooling designs, this layout forms a distributed cooling network on the entire rear end face of the display screen, which can reduce local overheating phenomena, ensure the temperature balance of each area of the display screen, and thus protect the display screen from shortened lifespan or performance degradation caused by local overheating. The "S" - shaped design of the coolant flow pipe 4 is not limited to the optimization of heat exchange. It also takes into account the structural stability. The complex pipe layout increases the mechanical strength of the pipe itself, reduces the risk of damage caused by external impact or vibration, and at the same time, by closely fitting with the rear end face of the display screen 2, it can also serve as an auxiliary support to enhance the overall structural stability of the display device. The "S" - shaped pipe design is more compact and flexible in the layout on the rear end face of the display screen 2, facilitating integration with other components (such as the cooling fan 3, the first liquid container 5, and the second liquid container 6). At the same time, the complex layout also means that for maintenance personnel, there are more opportunities to inspect, clean, and replace the pipes without significantly changing the overall structure of the display device, thereby extending the service life of the cooling system.

[0029] In this embodiment, the display device further includes a maintenance board 7, which is disposed on the side of the frame 1 away from the display screen. The maintenance board 7 and the frame 1 form a receiving cavity. A plurality of heat dissipation holes 8 are uniformly and penetratingly provided on the maintenance board 7. The heat dissipation holes 8 communicate with the receiving cavity. The heat dissipation fan 3 is located in the receiving cavity. The frame 1 and the maintenance board 7 are detachably connected.

[0030] Specifically, the existence of the maintenance board 7 not only provides protection for the internal components of the display device, but more importantly, it forms a receiving cavity with the frame 1, providing an independent heat dissipation space for the heat dissipation fan 3 and the liquid cooling component. The existence of the receiving cavity further ensures that the hot air discharged through the heat dissipation holes 8 can be quickly and effectively diffused into the external environment, rather than being guided back into the display device again, thus avoiding the cyclic accumulation of heat and improving the heat dissipation efficiency. The plurality of heat dissipation holes 8 penetratingly provided on the maintenance board 7 communicate with the receiving cavity, forming an effective air circulation path. When the heat dissipation fan 3 operates, through the guidance of the heat dissipation holes 8, the air convection inside and outside the receiving cavity can be promoted, accelerating the discharge of hot air and enhancing the effect of air-cooled heat dissipation. The detachable connection design between the maintenance board 7 and the frame 1 enables technical maintenance personnel to conveniently disassemble the maintenance board 7 and directly access the heat dissipation fan 3, the coolant flow pipe 4 and other internal components in the receiving cavity. This design greatly simplifies the maintenance process, reduces the maintenance cost, and is also convenient for cleaning the heat dissipation holes 8, ensuring the long-term stability and efficiency of the heat dissipation system. The uniform distribution of the heat dissipation holes 8 ensures that the air flow generated by the heat dissipation fan 3 can be evenly discharged through the heat dissipation holes 8, avoiding problems such as local overheating or uneven heat dissipation.

[0031] Specifically, both the length and width of the maintenance board 7 are greater than those of the display screen 2. Fixing blocks 43 are provided in the middle of the left and right sides of the maintenance board 7. Bolts are provided between the fixing blocks 43 and the rear end face of the frame 1. The bolts pass through the fixing blocks 43, the maintenance board 7 and the frame 1 to achieve the detachable connection between the frame 1 and the maintenance board 7.

[0032] In this embodiment, the liquid cooling component further includes a pump body 9, a first water suction pipe 10 and a second water suction pipe 11. The pump body 9 is communicated with the inner cavity of the first liquid containing member 5 through the first water suction pipe 10. The pump body 9 is also communicated with the coolant flow pipe 4 through the second water suction pipe 11, so that the pump body 9 pumps the coolant in the first liquid containing member 5 into the coolant flow pipe 4.

[0033] Specifically, through the introduction of the pump body 9, the first water suction pipe 10, and the second water suction pipe 11, the heat dissipation efficiency of the liquid cooling component has been significantly improved, effectively solving the problem of low heat dissipation efficiency of the display screen in the existing network information security teaching experiment device. Among them, through the constant pressure action of the pump body 9, it can ensure that the coolant flows stably and continuously in the liquid cooling component, improving the efficiency and reliability of liquid cooling heat dissipation. The connection of the pump body 9 with the first liquid storage member 5 and the coolant flow pipe 4 ensures that the coolant can be effectively extracted and transported to the coolant flow pipe 4, and then exchanges heat with the display screen 2 to absorb the heat generated during the operation of the display screen 2. The first water suction pipe 10 directly connects the pump body 9 with the inner cavity of the first liquid storage member 5, and this design enables the pump body 9 to directly extract the coolant from the first liquid storage member 5. The coolant is in a "standby" state in the first liquid storage member 5. When the pump body 9 is started, the coolant is sucked in through the first water suction pipe 10, ensuring the timely supply of the coolant. The second water suction pipe 11 connects the pump body 9 with the coolant flow pipe 4, enabling the coolant driven by the pump body 9 to directly flow into the coolant flow pipe 4 and closely contact the rear of the display screen 2 for heat exchange.

[0034] In this embodiment, a slot 12 is provided on the frame body 1, and a liquid injection port 13 is provided on the second liquid storage member 6. The liquid injection port 13 is connected to the inner cavity of the second liquid storage member 6; the liquid cooling component further includes a third water suction pipe, and the third water suction pipe passes through the slot 12 to be connected to the liquid injection port 13.

[0035] Specifically, the existence of the slot 12 provides a direct channel for the replenishment of the coolant. The combined use of the slot 12 and the liquid injection port 13 enables maintenance personnel to easily add coolant into the second liquid storage member 6 without disassembling the entire frame body 1 of the display device, improving the maintenance efficiency and convenience. The liquid injection port 13 is directly connected to the inner cavity of the second liquid storage member 6, ensuring that the coolant can enter the second liquid storage member 6 without obstruction, avoiding the obstruction of coolant flow caused by complex pipelines or poor connections, and enhancing the stability and reliability of the liquid cooling system. Through the replenishment of the coolant through the liquid injection port 13, the amount of coolant in the liquid cooling system can be adjusted in real time, ensuring that there is always enough coolant in the coolant flow pipe 4 for circulation, thereby maintaining the efficiency of liquid cooling heat dissipation and avoiding the decline in heat dissipation capacity caused by the reduction of the coolant due to evaporation or leakage. The addition of the third water suction pipe makes the process of replenishing the coolant more precisely controllable. Through the connection of the third water suction pipe with the liquid injection port 13, a pump body or other equipment can be used to precisely control the amount of coolant added, avoiding overfilling or underfilling that may occur during manual addition, and improving the operating efficiency and stability of the liquid cooling system. Through the third water suction pipe, not only can coolant be added, but also the coolant in the second liquid storage member 6 can be extracted when needed for inspection, replacement, or recycling. This design facilitates the management of the coolant and ensures the long-term stable operation of the liquid cooling system.

[0036] Specifically, a sealing cover is detachably arranged on the liquid injection port 13 for closing the liquid injection port 13.

[0037] In this embodiment, a connecting pipe 15 is arranged between the second liquid container 6 and the first liquid container 5, so that the coolant in the second liquid container 6 flows back to the first liquid container 5 through the connecting pipe 15.

[0038] Specifically, the main function of the connecting pipe 15 is to return the high-temperature coolant in the second liquid container 6 (after the coolant in the coolant flow pipe 4 absorbs heat, the coolant flows into this part) to the first liquid container 5, thereby jointly forming an efficient coolant circulation system with the pump body 9, the first water suction pipe 10, the coolant flow pipe 4 and the second water suction pipe 11. Through this circulation mechanism, the coolant can continuously flow inside the system, continuously absorb and release heat, ensuring the continuity and efficiency of the heat dissipation process. Among them, the connection of the connecting pipe 15 with the second liquid container 6 and the first liquid container 5 enables the coolant to form a closed circulation path within the system. This design avoids the single use and waste of the coolant, improves the utilization rate of the coolant, and at the same time reduces the frequency of coolant replenishment and maintenance costs, providing a continuous, stable and economical heat dissipation solution for the teaching experiment device. The coolant is driven by the pump body 9 from the first liquid container 5, absorbs the heat of the display screen 2 through the coolant flow pipe 4, flows into the second liquid container 6, and then returns to the first liquid container 5 through the connecting pipe 15. This process not only realizes the immediate removal of heat, but also ensures the balance of the coolant temperature in the entire liquid cooling system through the circulating flow, avoids local overheating, and improves the overall efficiency and reliability of the heat dissipation system. Through the reflux mechanism of the connecting pipe 15, the coolant can quickly return to the initial cooling state after heat dissipation, avoiding the accumulation of heat in the system. This efficient heat exchange and coolant recycling significantly improve the heat dissipation efficiency of the network information security teaching experiment device. Especially under high-load operation conditions, it can effectively control the temperature of the display screen and avoid performance degradation or equipment damage caused by overheating.

[0039] In this embodiment, two writing boards 40 and two lighting components 41 are arranged on the frame body 1. The two writing boards 40 are respectively arranged on both sides of the display screen 2, and the two lighting components 41 are arranged corresponding to the two writing boards 40 one by one, and each lighting component 41 is arranged above the corresponding writing board 40.

[0040] Specifically, the setting of the two writing boards 40 provides additional writing space for the instructor, allowing different teaching contents to be displayed simultaneously or real-time comparative analysis to be conducted, enhancing the interactivity and intuitiveness of teaching. When teaching network information security, one writing board 40 can be used to record key concepts, while the other writing board 40 can be used to display specific case analyses or technical details, thus helping students understand the teaching content more comprehensively and deeply. The addition of the two lighting elements 41 forms a one-to-one correspondence with the writing boards 40, and each lighting element 41 is arranged directly above the corresponding writing board 40. This design can provide direct lighting for the writing board, avoiding the influence of insufficient ambient light on teaching activities and ensuring that the written content is clearly visible. Especially in a dark or weakly lit teaching environment, the role of the lighting element 41 is more prominent, enabling students to clearly see the content on the writing board regardless of their seating position, improving the transmission efficiency of teaching information.

[0041] Optionally, the lighting element 41 is an LED lighting lamp.

[0042] In this embodiment, the display device further includes a support platform 20, and a frame 1 is arranged on the upper surface of the support platform 20; wherein, two fixing rods 21 are arranged on the lower surface of the support platform 20, a placement board 22 is arranged between the two fixing rods 21, and the placement board 22 is used for placing a control member 211; and / or, a support rod 23 extending in the vertical direction is further arranged on the lower surface of the support platform 20, and a moving wheel 24 is arranged at the bottom of the support rod 23.

[0043] Specifically, the support platform 20 is located below the frame 1, forming a stable up-and-down structure with the frame 1, increasing the stability of the entire display device. The setting of the placement board 22 provides a dedicated placement space for the control member 211. This layout optimization enables the control member 211 to be properly placed, which is not only convenient for the operator to use but also avoids the influence of environmental factors such as moisture and dust that may be encountered when the control member 211 is directly placed on the ground, extending the service life of the control member. The combination of the support rod 23 and the moving wheel 24 endows the display device with excellent mobility. In teaching experiments, it is often necessary to move the equipment from one place to another, and the design of the moving wheel 24 makes this process easy and simple, and the movement can be completed without additional manpower or equipment. At the same time, the support rod 23 is arranged on the lower surface of the support platform 20 to ensure the stability during movement and avoid equipment damage caused by improper movement.

[0044] Optionally, the control member is a controller for the user to manipulate the display screen 2; the moving wheel 24 is a universal wheel.

[0045] Specifically, a rotating table is provided at the center of the top of the support platform 20. A bearing is provided inside the rotating table 42, and a frame 1 is provided at the top of the rotating table 42. The angle of the frame 1 can be rotationally adjusted through the rotating table 42.

[0046] In this embodiment, a first fixed frame 25 is provided on the support platform 20. The first fixed frame 25 is located below the maintenance board 7. A first storage opening is provided at the top of the first fixed frame 25 for an operating member 27 to pass through and enter the first fixed frame 25. Among them, the operating member 27 is communicatively connected to the display screen 2.

[0047] Specifically, the setting of the first fixed frame 25 provides physical support and protection for the operating member 27 (usually a computer main unit). By positioning the operating member 27 inside the first fixed frame 25, not only is it protected from damage due to external impacts during transportation or use, but also the structural design of the fixed frame can effectively disperse and absorb the vibrations generated by the operating member 27 itself, further protecting the electronic components of the operating member 27 and extending its service life. The first fixed frame 25 is located below the maintenance board 7 and has a first storage opening at the top. Such a layout design not only makes full use of the space on the support platform 20 but also ensures that the operating member 27 does not block the cooling fans and cooling holes, guaranteeing the unobstructed flow of cooling air. The setting of the first storage opening enables the operating member 27 to be easily taken out or put into the first fixed frame 25 while remaining relatively fixed. This design greatly improves the maintainability and accessibility of the operating member 27. Whether for daily inspections, cleaning, or maintenance, it can be carried out quickly and conveniently without disassembling the entire device, saving time and labor costs.

[0048] Optionally, the first fixed frame 25 is a metal frame with strong structural stability and is not easily deformed or damaged. Round holes are provided at the bottom of the first fixed frame 25, which can play an effect of increasing heat dissipation and dissipate heat from the bottom of the operating member 27.

[0049] Specifically, a rectangular groove is provided at the center of the front end face of the top of the support platform 20, where some teaching aids commonly used in daily life can be placed; book placement areas are provided on both the left and right sides of the top of the support platform 20. When conducting network information security teaching, some relevant books can be placed on the book placement areas for easy access; handles are provided at the centers of both the left and right sides of the support platform 20, which can facilitate lifting the entire device and thus facilitate handling and moving.

[0050] Specifically, arc-shaped chamfers are provided at the four corners of the outer periphery of the frame 1 to prevent the frame 1 from scratching the users.

[0051] In this embodiment, a second fixing frame 28 is provided on the support platform 20. The second fixing frame 28 is located below the display screen 2. A second placing opening is provided at the top of the second fixing frame 28 for the input member 30 to pass through and enter the second fixing frame 28. Among them, both the display screen 2 and the input member 30 are communicatively connected to the operating member 27.

[0052] Specifically, the second fixing frame 28 is located below the display screen 2 and is designed with a second placing opening. This layout effectively utilizes the space below the display device, provides a suitable placement position for the input member 30 (such as a keyboard, mouse, etc.), and avoids space waste or inconvenient operation caused by random placement of input devices. At the same time, through the design of the second placing opening, the input member 30 can conveniently pass through and enter the second fixing frame 28, which not only realizes the integration of the devices, but also keeps the operation area clean, improving the professionalism and aesthetics of the overall device. The setting of the second fixing frame 28 not only provides a fixed placement position for the input member 30, but also plays a certain protective role, reducing the risk of damage to the device due to accidental collision or improper placement. At the same time, the design of the fixing frame usually takes into account the maintenance requirements of the device, enabling easy removal or disassembly when cleaning or inspecting the input member, reducing the maintenance cost and time, and ensuring the long-term stable operation of the teaching experiment device.

[0053] Optionally, there are two input members 30, namely a keyboard and a mouse. A placement groove is provided in the second fixing frame 28. The keyboard is placed on the left side of the placement groove, and the mouse is placed on the right side of the placement groove. The keyboard and the mouse are respectively communicatively connected to the operating member 27, and the operating member 27 (computer main unit) and the display screen 2 can be operated through the keyboard and the mouse.

[0054] In this embodiment, a fixing rack is provided in the accommodation cavity of the frame body 1, and a plurality of fixing buckles 32 are provided on the fixing rack. The coolant flow pipe 4 passes through each fixing buckle 32; and / or, a heat dissipation opening is provided at the top of the frame body 1, and the heat dissipation opening is communicated with the accommodation cavity.

[0055] Specifically, the multiple fixing buckles 32 on the fixing frame can effectively fix the coolant flow pipe 4, avoiding displacement or damage of the coolant flow pipe caused by equipment vibration or movement. This stability is particularly important for the liquid cooling system because it ensures that the coolant can flow in the preset path without affecting the heat dissipation efficiency or causing coolant leakage due to the shaking of the pipeline, thereby protecting key components such as the display screen from damage. Through the positioning of the fixing buckle 32, the direction and layout of the coolant flow pipe 4 can be precisely controlled to ensure that it can maintain the best thermal contact with heat-generating components such as the display screen, improving the heat exchange efficiency. The "S"-shaped layout behind the display screen, combined with the positioning of the fixing buckle, enables the coolant flow pipe to evenly cover the rear end face of the display screen, avoiding the problem of insufficient local heat dissipation and ensuring that the temperature of the display screen can be effectively controlled. The use of the fixing buckle 32 reduces the mechanical stress that the coolant flow pipe 4 may be subjected to during long-term use, such as bending, stretching, and extrusion, thereby extending the service life of the coolant flow pipe. This is particularly important for reducing maintenance costs and improving the overall reliability of the device.

[0056] Specifically, the heat dissipation opening at the top of the frame body 1 is connected to the accommodation cavity, which can significantly enhance air circulation and help the liquid cooling component discharge the absorbed heat. Especially in a closed or semi-closed environment, the presence of the heat dissipation opening can ensure that the hot air can be quickly discharged, avoiding heat accumulation inside and being beneficial to improving the heat dissipation effect of the entire display device. The design of the heat dissipation opening helps to reduce the temperature inside the display device, thereby protecting all electronic devices including the display screen and the controller from performance degradation or damage caused by overheating. This plays an important role in ensuring the smooth progress of network information security teaching experiments and extending the service life of the display device. By setting the heat dissipation opening at the top, natural convection or auxiliary fans can be used for heat dissipation, reducing the dependence on the active heat dissipation system (such as the heat dissipation fan 3), thereby reducing energy consumption, improving the energy efficiency ratio of the display device, and significantly enhancing the heat dissipation efficiency of the display screen 2.

[0057] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0058] The display device of the present invention includes a frame 1, a cooling fan 3 and a liquid cooling component. A display screen 2 is provided on the frame 1. The liquid cooling component includes a coolant flow pipe 4, a first liquid container 5 and a second liquid container 6. By arranging the cooling fan 3 facing the display screen 2, the cooling fan can directly perform air cooling on the display screen 2 to accelerate the heat dissipation from the surface of the display screen 2. At the same time, by closely attaching the coolant flow pipe 4 behind the display screen 2, the coolant in the first liquid container 5 flows through the coolant flow pipe 4 into the second liquid container 6, so that the coolant directly absorbs the heat generated by the display screen 2 during the working state when flowing through the coolant flow pipe 4. The cooling effect of the liquid cooling component is usually better than that of air cooling because it utilizes the high heat capacity and thermal conductivity of the coolant and can more effectively take away a large amount of heat. The dual cooling mechanism of the cooling fan 3 and the liquid cooling component enables the display screen 2 to dissipate heat more quickly and evenly, improves the heat dissipation efficiency of the display screen, and solves the problem of low heat dissipation efficiency of the display screen in the existing network information security teaching experiment device.

[0059] For the sake of convenience in description, spatial relative terms, such as "above", "over", "on the upper surface", "upper", etc., can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure for the device.

[0060] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without further statement, the above terms have no special meanings, so they cannot be understood as limiting the protection scope of the present application.

[0061] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
