Abstract
Description
Technical Field
[0001] This utility model relates to the field of advertising screen technology, and in particular to a heat dissipation splicing advertising screen. Background Technology
[0002] A video wall display is a flat panel display composed of small LED module panels. It is used to display various information such as text, images, videos, and video recordings, and is widely used in shops, shopping malls, and other places. However, outdoor advertising screens are subjected to both direct sunlight and wall radiation over extended periods, leading to a significant decrease in their heat dissipation performance. Direct sunlight causes a rapid increase in the screen's surface temperature, which is then conducted to internal electronic components, exceeding their normal operating temperature range. Simultaneously, secondary heating from heated walls further hinders heat dissipation, creating a high-temperature environment around the equipment and reducing the efficiency of the active cooling system. This sustained high temperature accelerates LED light decay, degrades driver circuit performance, and reduces power module stability, ultimately shortening the display's lifespan and significantly increasing the failure rate. Utility Model Content
[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0004] To address the aforementioned problems, this utility model provides the following technical solution: A heat-dissipating splicing advertising screen includes several display screen groups mounted on a support frame. The back of the support frame is fixedly connected to a wall, and a heat-insulating groove is recessed on the back. A cavity is opened through the side of the support frame, and heat dissipation fins are provided inside. A receiving groove is opened on the front of the support frame, and the outer surface of the receiving groove is fixedly connected to one end of the heat dissipation fins.
[0005] Preferably, the cavity, the receiving groove, and the heat dissipation fins are all integrally formed on the support frame.
[0006] Preferably, the electronic device of the display panel is disposed in the receiving groove, and the outer surface of the display panel is movably engaged with the support frame through the assembly port opened at the edge of the receiving groove.
[0007] Preferably, the two ends of the support frame are provided with expansion tubes extending along the cavity, and the expansion tubes between adjacent support frames are connected to form a first heat dissipation channel.
[0008] Preferably, a ventilation opening is provided on the outer surface of the box perpendicular to the support frame, and the ventilation opening is connected to the receiving groove.
[0009] Preferably, a second heat dissipation channel is formed between the longitudinally adjacent support frames, and the vent is connected to the second heat dissipation channel.
[0010] Preferably, the support frame is provided with mounting protrusions on the outer edge of the heat insulation groove. The mounting protrusions are provided with threaded holes, and the back of the support frame is fixed to the wall by screws. The heat insulation groove separates the support frame from the wall.
[0011] The beneficial effects of this utility model are as follows: The back of the support frame is fixedly connected to the wall, and a heat-insulating space is formed through the heat-insulating groove. Its side has a cavity with heat dissipation fins, which is not connected to the heat-insulating groove. A display screen assembly is installed at the front end of the support frame, and the heat dissipation fins are connected to the display screen assembly to reduce temperature. The heat-insulating groove isolates the display screen assembly from heat conduction between it and the wall, and the cavity achieves ventilation and heat dissipation. The front end of the support frame has no connection to the cavity, thus also providing waterproof and dustproof functions. Attached Figure Description

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0021] Example Reference Figures 1 to 5 This embodiment of the present invention provides a heat dissipation splicing advertising screen, including a plurality of display screen groups 200 disposed on a support frame 100. The back of the support frame 100 is fixedly connected to a wall, and a heat insulation groove 105 is recessed on the back. A cavity 102a is opened through the side of the support frame 100, and a heat dissipation fin 103 is provided inside. A receiving groove 104 is opened on the front of the support frame 100, and the outer surface of the receiving groove 104 is fixedly connected to one end of the heat dissipation fin 103. Specifically, the back of the support frame 100 is fixedly connected to the wall, and a heat-insulating space separated from the wall is formed by the heat-insulating groove 105. A cavity 102a is formed through the side of the support frame 100, and the heat-insulating groove 105 and the cavity 102a are not connected. A display screen assembly 200 is installed at the front end of the support frame 100. The heat-insulating groove 105 effectively isolates heat conduction between the display screen assembly 200 and the wall, while the cavity 102a on the side serves for ventilation and heat dissipation. Furthermore, heat dissipation fins 103 are provided inside the cavity 102a and connected to the display screen assembly 200 at the front end of the support frame 100, which can significantly reduce the temperature of the electronic equipment area of the display screen assembly 200. At the same time, since the front end of the support frame 100 is not connected to the cavity 102a, it can effectively prevent water and dust from entering even in rainy weather, thus ensuring both heat dissipation performance and protective functions.
[0022] For example, the support frame 100 is provided with mounting protrusions 106 on the outer edge of the heat insulation groove 105. The mounting protrusions 106 are provided with threaded holes 106a. The back of the support frame 100 is fixed to the wall by screws, and the heat insulation groove 105 separates the support frame 100 from the wall.
[0023] For example, the cavity 102a, the receiving groove 104, and the heat dissipation fins 103 are all integrally formed on the support frame 100. The integral forming design avoids assembly gaps, ensures the overall strength of the support frame 100, and facilitates its processing and forming.
[0024] The electronic equipment of the display panel 200 is housed in the receiving groove 104. The outer surface of the display panel 200 is movably engaged with the support frame 100 through the assembly port 104a opened on the edge of the receiving groove 104. The display panel 200 and the support frame 100 are movably engaged, so that if a single module of the display panel 200 is damaged, it can be quickly replaced.
[0025] For example, the two ends of the support frame 100 are provided with expansion tubes 102 extending along the cavity 102a. The expansion tubes 102 between adjacent support frames 100 are connected to form a first heat dissipation channel 300. In this embodiment, each display screen group 200 module corresponds to one support frame 100. The expansion tubes 102 at both ends of the support frame 100 are connected one by one to form a first heat dissipation channel 300 in the transverse direction, thereby achieving cooling of the surface of the heat dissipation fins 103 in the cavity 102a.
[0026] A ventilation opening 104b is provided on the outer surface of the box 101 perpendicular to the support frame 100. The ventilation opening 104b is connected to the receiving groove 104. If the first heat dissipation channel 300 has low heat dissipation efficiency due to poor ventilation, it can be connected to the outside through the ventilation opening 104b connected to the receiving groove 104, so as to realize an open receiving groove 104 to improve the heat dissipation effect and cope with the more complex external environment.
[0027] A second heat dissipation channel 400 is formed between longitudinally adjacent support frames 100. The vent 104b is connected to the second heat dissipation channel 400. A partition can be set between the outermost longitudinally adjacent support frames 100 to seal both ends of the second heat dissipation channel 400 for rain protection. Its interior is connected to the vent 104b. In this way, even when the heat dissipation effect of the first heat dissipation channel 300 is not good, it still has a certain heat dissipation effect on the electronic equipment of the display screen group 200.
[0028] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values (e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application). For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of elements may be inverted or otherwise altered, and the nature or number or position of discrete elements may be changed or altered. Therefore, all such modifications are intended to be included within the scope of this utility model.
