Technical Field
[0001] This utility model relates to the field of backplate technology, specifically to a steel backplate for OLED displays that facilitates heat dissipation. Background Technology
[0002] The heat-dissipating steel backplate for OLED displays is a backplate structure specifically designed for OLED displays. It is made of steel and utilizes the high thermal conductivity of steel to improve the heat dissipation efficiency of the display. Through optimized design, this backplate can effectively reduce the temperature of the OLED screen under long-term operation or high load, thereby extending the screen's lifespan and maintaining its performance stability. The steel backplate for OLED displays is a metal component used to support and protect the OLED screen. It is usually made of high-strength steel and has good structural stability and heat dissipation performance. It can provide a solid support for the OLED screen and help dissipate the heat generated when the screen is working, ensuring the stable operation and lifespan of the display. Existing OLED displays typically use sheet-like steel backplates. Due to the relatively low thermal conductivity of steel, heat dissipation efficiency is limited. To improve heat dissipation performance, heat dissipation channels, such as ventilation holes or heat sinks, are usually set on the backplate. However, the setting of these heat dissipation channels will create stress concentration areas on the backplate, especially at the edges of ventilation holes or heat sinks. During long-term use, these stress concentration areas may cause fatigue fracture of the backplate, thereby affecting the overall reliability and service life of the display. Therefore, a heat dissipation-friendly steel backplate for OLED displays is proposed to address the above problems. Utility Model Content

A heat dissipation component is fixedly connected to the inner side of the backplate assembly.

[0016] Please see Figures 1-7 This utility model provides a technical solution: A heat dissipation-friendly steel backplate for an OLED display includes a backplate assembly 1. A heat dissipation assembly 2 is fixedly connected to the inner side of the backplate assembly 1. The backplate assembly 1 includes a backplate body 11, with a vent hole 14 and a reserved screw hole 15 on the inner side of the backplate body 11. The heat dissipation assembly 2 includes a first annular aluminum alloy tube 21, with an extension tube 22 fixedly connected to the inner side of the first annular aluminum alloy tube 21 and a support tube 23 fixedly connected to the outer side of the first annular aluminum alloy tube 21. The first annular aluminum alloy tube 21 and the second annular aluminum alloy tube 24 are integrally fixed structures. Both the inner side of the first annular aluminum alloy tube 21 and the inner side of the second annular aluminum alloy tube 24 have annular grooves 25. Both the inner side of the first annular aluminum alloy tube 21 and the inner side of the second annular aluminum alloy tube 24 have internal tubes 26 fixedly connected. An extension hole 27 is opened on the inner side of the internal tube 26. A fixing plate 28 is fixedly connected to one side of the support tube 23, with a vent 29 opened on the inner side of the fixing plate 28.
[0017] As a further implementation of this solution, a heat dissipation mounting groove 12 and a lamp mounting groove 13 are provided on the inner side of the back panel body 11. The heat dissipation mounting groove 12 and the lamp mounting groove 13 are connected. The heat dissipation mounting groove 12, the vent hole 14 and the reserved screw hole 15 are connected. The vent hole 14 is aligned with the vent 29 on the left and right. The vent hole 14 is connected with the vent 29. With the above settings, the extra openings are eliminated, the back panel remains intact, the strength is not reduced, the airflow can still pass through continuously, the heat is carried away faster, and a direct ventilation channel is formed. The cold air enters the heat source center directly from the side. The heat exchange path is short and the heat dissipation speed is significantly accelerated. As a further implementation of this solution, the fixing plate 28 has a threaded hole on its inner side. The threaded hole of the fixing plate 28 is aligned with the reserved screw hole 15 on the left and right. The fixing plate 28 is fixedly connected to the back plate body 11 by bolts. The heat dissipation component 2 is embedded in the heat dissipation mounting groove 12. The heat dissipation component 2 is located at the lower end of the lamp groove 13. Through the above settings, the heat dissipation component 2 is fixed inside the back plate body 11, so that the heat dissipation component 2 is close to the lamp plate, thereby improving the effectiveness of heat dissipation inside the back plate body 11. As a further implementation of this solution, the first annular aluminum alloy tube 21 and the second annular aluminum alloy tube 24 are both hollow circular structures. The multiple first annular aluminum alloy tubes 21 are circular structures with different diameters, and the centers of the multiple first annular aluminum alloy tubes 21 coincide. The structure of the second annular aluminum alloy tube 24 is the same as that of the first annular aluminum alloy tube 21. Through the above arrangement, the multi-ring concentric circle structure allows the external force to be evenly distributed to each ring, improving the bending resistance of the back plate. At the same time, the cavity inside the ring increases the contact area with the air, and heat dissipation and reinforcement are completed simultaneously. As a further implementation of this solution, the inner side of the extension tube 22 is connected to the inner side of the first annular aluminum alloy tube 21. The extension tube 22 is fixed in a circumferential array inside multiple first annular aluminum alloy tubes 21. The extension tube 22 is fixed inside the second annular aluminum alloy tube 24. Through the above arrangement, the strength and overall reliability of the back plate body 11 are improved, and cracks are less likely to occur after long-term use.
[0018] Workflow: During installation, first place the heat dissipation component 2 as a whole inside the heat dissipation mounting groove 12 through the lamp mounting groove 13. At this time, the entire section of the fixing plate 28 is attached to the lower end of the heat dissipation mounting groove 12. Move the heat dissipation component 2 as a whole until the threaded hole of the fixing plate 28 is aligned with the reserved screw hole 15. Then, fix the fixing plate 28 to the back plate body 11 with bolts. The bolts are fixed inside the threaded hole and the reserved screw hole 15 of the fixing plate 28. Then fix the lamp board inside the lamp mounting groove 13. In use, the first annular aluminum alloy tube 21, the extension tube 22, and the second annular aluminum alloy tube 24 absorb the heat generated by the lamp panel, thereby cooling the interior of the back panel body 11. At the same time, external air can enter the inner side of the support tube 23, the annular groove 25, and the interior of the second annular aluminum alloy tube 24 through the vent hole 14 and the vent 29. Moreover, the extension hole 27 penetrates the interior of the first annular aluminum alloy tube 21 and the built-in tube 26, which facilitates the entry of hot air into the lower end of the first annular aluminum alloy tube 21 and the lower end of the second annular aluminum alloy tube 24 through the extension hole 27, thereby improving the uniformity and efficiency of heat absorption. The multiple first annular aluminum alloy tubes 21, multiple extension tubes 22, and multiple second annular aluminum alloy tubes 24 are connected, so that when external air passes through the interior of the first annular aluminum alloy tubes 21, the extension tube 22, and the second annular aluminum alloy tube 24, it carries the hot air out, thereby achieving the purpose of heat exchange and improving the sustainability of cooling. When increasing strength, since the first annular aluminum alloy tube 21 and the second annular aluminum alloy tube 24 are both circular structures, the strength of the support for the back plate body 11 is improved. At the same time, through the connection design of the extension tube 22, the extrusion pressure can be distributed among multiple first annular aluminum alloy tubes 21 and multiple second annular aluminum alloy tubes 24, which further improves the strength of the support. Based on the above principles, the device changes the traditional heat dissipation method of opening heat dissipation channels on the back plate body 11, so that the device can have a good heat dissipation effect on the inside of the back plate body 11 during operation. At the same time, this heat dissipation structure also provides internal support for the back plate body 11, improving the strength and overall reliability of the back plate body 11 and reducing the phenomenon of fatigue fracture of the back plate body 11.
[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
