Description

Technical Field

[0001] This utility model relates to the field of display screen glass cover technology, and in particular to a glass cover for an industrial control computer display screen with good heat dissipation. Background Technology

[0002] Industrial control computers (ICCs) are widely used in harsh environments such as factory automation, machinery manufacturing, power monitoring, and rail transportation. As a crucial window for human-machine interaction, the reliability and stability of their displays are paramount. Currently, the core components of an ICC display typically consist of an outer glass cover, an internal liquid crystal display module, and possibly an integrated touchscreen layer. In existing technologies, the main functions of this glass cover focus on light transmittance, surface hardness, protection, and interference resistance. Commonly used cover materials, such as soda-lime glass, aluminosilicate glass, or chemically tempered glass, are designed and selected primarily to meet the aforementioned optical, mechanical, and environmental protection requirements. Structurally, they are usually a single, flat glass layer or a composite layer. Regarding heat dissipation, current solutions mainly rely on the overall heat dissipation design of the ICC chassis or localized heat dissipation measures behind the display module.

[0003] However, the aforementioned existing technologies have the following prominent problems: Poor heat dissipation performance of glass cover plates: Industrial control computers are often deployed in high-temperature, dusty, and enclosed environments. The internal electronic components generate a lot of heat when they are working. Due to the low thermal conductivity of the material itself and the lack of active heat dissipation considerations in the structural design of existing glass cover plates, they cannot effectively conduct or dissipate the heat radiated and conducted forward by the display module, as well as the absorbed environmental heat radiation. This causes the temperature of the inner surface of the cover plate and the adjacent display module to rise continuously, hindering the heat dissipation path to the front of the equipment. This not only aggravates the thermal burden on the display module, but also easily leads to slower LCD response speed, color deviation, brightness decay, or even permanent damage. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a glass cover for an industrial control computer display screen with good heat dissipation, effectively solving the deficiencies of the prior art.

[0005] The purpose of this utility model is achieved through the following technical solution: a glass cover plate for an industrial control computer display screen with good heat dissipation effect, comprising a substrate glass layer, a heat-conducting thin film layer of high light transmittance material fixedly bonded to the substrate glass layer and the surface of the display screen, a metal support frame fixedly connected to the edge side of the substrate glass layer, the metal support frame being physically heat-conductingly connected to the heat-conducting thin film layer, and a heat dissipation structure area provided on the outer surface of the metal support frame, the heat dissipation structure area dissipating heat by increasing the air contact area.

[0006] Preferably, the thermally conductive thin film layer is either an aluminum nitride ceramic thin film or a diamond thin film, and the thickness of the thermally conductive thin film layer is 20–50 micrometers.

[0007] The thermally conductive thin film layer is bonded to the substrate glass layer via physical vapor deposition.

[0008] The technical effect achieved by adopting the above solution is to improve heat dissipation while reducing the impact on the display.

[0009] Preferably, in any of the above solutions, the heat dissipation structure area is a plurality of heat dissipation protrusions and ribs integrally formed with the metal support frame, and the plurality of heat dissipation protrusions and ribs are evenly distributed around the periphery of the metal support frame.

[0010] The technical effect achieved by adopting the above solution is that the air contact area can be increased by several protruding ribs, thereby improving the heat dissipation effect.

[0011] Preferably, in any of the above embodiments, the inner side of the metal support frame is a groove-shaped structure, and the edge of the substrate glass layer is embedded in the groove-shaped structure inside the metal support frame.

[0012] The technical effect achieved by adopting the above solution is that the groove structure can wrap around the edge of the substrate glass layer, improving protection, while increasing the thermal contact area and improving the heat dissipation effect.

[0013] Preferably, in any of the above embodiments, the edge of the thermally conductive thin film layer extends to the side and top edge of the substrate glass layer, the inner wall of the groove structure inside the metal support frame is coated with a silicone grease contact layer, and the groove structure inside the metal support frame is in contact with the edge of the thermally conductive thin film layer through the silicone grease contact layer.

[0014] The technical effect achieved by adopting the above solution is that the thermal conductivity of the contact surface can be improved by connecting the metal support frame and the substrate glass layer through the silicone grease contact layer.

[0015] This utility model has the following advantages: 1. This industrial control computer display screen glass cover with good heat dissipation effect is in contact with the outer surface of the display screen through a thermally conductive film layer. Through its excellent thermal conductivity, the heat emitted by the display screen can be evenly distributed and conducted to the surface of the metal support frame, thereby transferring it out of the space between the substrate glass layer and the display screen. Furthermore, the heat dissipation structure area on the outside of the metal support frame expands the air contact area, which can improve heat dissipation efficiency, achieve rapid heat dissipation, reduce the temperature of the display screen, and extend its service life.

[0016] 2. The industrial control computer display screen glass cover with good heat dissipation effect is surrounded by a metal support frame around the edge of the base glass layer. This not only protects the edge of the base glass layer, but also guides heat dissipation in all directions, expands the heat dissipation area, and improves the heat dissipation effect.

[0019] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0020] like Figure 1 As shown, a glass cover for an industrial control computer display screen with good heat dissipation includes a substrate glass layer 1, a thermally conductive thin film layer 2 of high light transmittance material fixedly bonded to the substrate glass layer 1 and the surface of the display screen, a metal support frame 3 fixedly connected to the edge side of the substrate glass layer 1, the metal support frame 3 being physically thermally connected to the thermally conductive thin film layer 2, and a heat dissipation structure area 4 provided on the outer surface of the metal support frame 3, which dissipates heat by increasing the air contact area.

[0021] As an optional technical solution of this utility model: the thermally conductive film layer 2 is either an aluminum nitride ceramic film or a diamond film, the thickness of the thermally conductive film layer 2 is 20-50 micrometers, and the thermally conductive film layer 2 is bonded to the substrate glass layer 1 by physical vapor deposition. Both aluminum nitride ceramic film and diamond film have excellent thermal conductivity and light transmittance, which improves the heat dissipation effect while reducing the impact on the display.

[0022] As an optional technical solution of this utility model: the heat dissipation structure area 4 is a plurality of heat dissipation protrusions ribs integrally formed with the metal support frame 3. The plurality of heat dissipation protrusions ribs are evenly distributed around the periphery of the metal support frame 3. The plurality of protrusions ribs can increase the air contact area and improve the heat dissipation effect.

[0023] As an optional technical solution of this utility model: the inner side of the metal support frame 3 is a groove structure, and the edge of the substrate glass layer 1 is embedded in the groove structure inside the metal support frame 3. The groove structure can wrap the edge of the substrate glass layer 1, improve protection, and at the same time increase the thermal contact area and improve the heat dissipation effect.

[0024] As an optional technical solution of this utility model: the edge of the thermally conductive thin film layer 2 extends to the edge of the side and top surface of the substrate glass layer 1, the inner wall of the groove structure inside the metal support frame 3 is coated with a silicone grease contact layer, the groove structure inside the metal support frame 3 is in contact with the edge of the thermally conductive thin film layer 2 through the silicone grease contact layer, and the metal support frame 3 and the substrate glass layer 1 are connected through the silicone grease contact layer, which can improve the thermal conductivity of the contact surface.

[0025] Example 1: This embodiment provides a glass cover for an industrial computer display screen with good heat dissipation: Substrate glass layer: Chemically strengthened aluminosilicate glass is selected as the substrate glass layer, which has good mechanical strength and impact resistance.

[0026] Thermally conductive thin film layer: Material and thickness: A diamond film with a thickness of 40 micrometers is deposited on the inner surface of the substrate glass layer (i.e., the surface that is bonded to the industrial control computer display module) as a thermally conductive thin film layer using a physical vapor deposition process. This diamond film has extremely high thermal conductivity and excellent light transmittance (greater than 90%).

[0027] Metal Support Frame: Material and Structure: A metal support frame made of aluminum alloy is fixedly connected to the edge of the substrate glass layer. The inner side of the support frame is designed with a groove structure to precisely match the edge of the glass.

[0028] Assembly: The edge of the substrate glass layer is embedded in the groove structure to achieve mechanical fixation.

[0029] Thermally conductive connection: Thermally conductive film extension: The edge of the diamond thermally conductive film layer extends to the side of the substrate glass layer and a small portion of the top surface near the edge.

[0030] Silicone grease layer: A layer of high thermal conductivity silicone grease is uniformly applied to the inner wall of the groove structure of the metal support frame, especially in the area in contact with the extended thermally conductive thin film layer, to form a silicone grease contact layer.

[0031] Contact: After assembly, the grooved structure of the metal support frame is in close contact with the edge of the extended diamond thermally conductive film layer through the silicone grease contact layer, establishing an efficient physical heat conduction channel.

[0032] Heat dissipation structure area: On the outer surface of the metal support frame, sixteen evenly distributed heat dissipation protrusions are integrally processed through extrusion molding to form the heat dissipation structure area.

[0033] Function: These ribs significantly increase the contact area between the metal support frame and the surrounding air.

[0034] Working Principle and Effects: The heat generated by the industrial computer's display module during operation is first transferred to the diamond thermally conductive film layer tightly bonded to it. Thanks to the extremely high thermal conductivity of the diamond film, the heat is rapidly and evenly conducted to the surrounding area. After being conducted to the extended portion of the thermally conductive film at the edge, the heat is efficiently transferred to the aluminum alloy metal support frame through the silicone grease contact layer. The aluminum alloy support frame itself is an excellent thermal conductor, allowing the heat to diffuse rapidly within it. Finally, the heat is transferred to the heat dissipation ribs on the outer surface of the support frame. These ribs increase the heat dissipation area, facilitating heat exchange with the air and dissipating the heat into the environment. This structure effectively reduces the temperature at the interface between the display module and the glass cover, minimizing LCD response delay and color shift risks, and extending the display's lifespan.

[0035] Example 2: Product Structure: This embodiment provides another type of industrial control computer display glass cover with good heat dissipation.

[0036] Substrate glass layer: Soda-lime glass is selected as the substrate glass layer.

[0037] Thermally conductive thin film layer: Material and thickness: A 30-micrometer-thick aluminum nitride ceramic thin film is deposited on the inner surface of the substrate glass layer using physical vapor deposition as a thermally conductive thin film layer. This film also possesses high thermal conductivity and good optical transmittance (greater than 92%).

[0038] Metal support frame: Material and structure: A metal support frame made of copper alloy is fixedly connected to the edge of the substrate glass layer, and the inner side of the frame is also designed with a matching groove structure.

[0039] Assembly: The edge of the substrate glass layer is embedded in the groove-shaped structure for fixation.

[0040] Thermally conductive connection: Thermally conductive film extension: The edge of the aluminum nitride thermally conductive film layer extends to the side and top edge areas of the substrate glass layer.

[0041] Silicone grease layer: High thermal conductivity silicone grease is applied to the inner wall of the groove structure of the metal support frame (corresponding to the contact surface of the thermally conductive film).

[0042] Contact: After assembly, the copper alloy support frame achieves close thermal contact with the edge of the extended aluminum nitride thermally conductive film layer through the silicone grease contact layer.

[0043] Heat dissipation structure area: Form: Around the outer perimeter of the copper alloy metal support frame, twenty fine and evenly distributed heat dissipation protrusions are integrally formed by precision casting, forming the heat dissipation structure area.

[0044] Function: Compared to Example 1, the more numerous and finer ribs further increase the heat dissipation surface area.

[0045] Working Principle and Effects: Heat from the display module is efficiently conducted to the aluminum nitride thin film layer and quickly directed to the edges. The copper alloy support frame has excellent thermal conductivity, rapidly absorbing and dissipating heat from the film edges. The heat is ultimately transferred to the dense heat dissipation fins on its outer surface. The fin structure greatly enhances the convective heat transfer efficiency with the air, accelerating heat dissipation. This design significantly improves the heat dissipation capacity of the glass cover while maintaining good light transmittance and protection. It is particularly suitable for industrial control computer displays in high-power or high-temperature environments, effectively preventing brightness degradation and component damage caused by overheating.

[0046] In summary, this invention, through the thermally conductive thin film layer 2 being bonded to the outer surface of the display screen, utilizes its superior thermal conductivity to evenly distribute and conduct the heat emitted by the display screen to the surface of the metal support frame 3, thereby transferring it away from the space between the substrate glass layer 1 and the display screen. Furthermore, the heat dissipation structure area 4 on the outer side of the metal support frame 3 expands the air contact area, which can improve heat dissipation efficiency, achieve rapid heat dissipation, reduce the temperature of the display screen, and extend its service life. By having the metal support frame 3 surround the edge of the substrate glass layer 1, it can not only protect the edge of the substrate glass layer 1 but also guide heat dissipation in all directions, expanding the heat dissipation area and improving the heat dissipation effect.
