Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of LED display screens, and in particular to a heat dissipation structure for a smart water cup and a light display device with the same. BACKGROUND

[0002] LED display screens are widely used in various display devices, especially in high-brightness and high-performance display requirements. LED lamp beads generate a large amount of heat. If the heat cannot be effectively dissipated, it may cause the LED display effect to decrease, the service life of the lamp beads to be shortened, and even the device to be damaged. Therefore, the heat dissipation design of the LED display screen is the key to ensuring its stable operation for a long time. The present application proposes a heat dissipation structure for a smart water cup, which is suitable for effectively dissipating heat for the LED display screen in the smart water cup. SUMMARY

[0003] Therefore, the present application proposes a heat dissipation structure for a smart water cup and a light display device with the same

[0004] According to an aspect of the present application, a heat dissipation structure for a smart water cup is provided, which is suitable for dissipating heat for an LED display screen installed in the smart water cup, and includes a first heat conduction layer and a second heat conduction layer.

[0005] The first heat conduction layer and the second heat conduction layer are both curved surface structures. The first heat conduction layer is located in the middle of the LED display screen and the second heat conduction layer, and one side of the first heat conduction layer is suitable for being attached to the back of the LED display screen. One side of the second heat conduction layer is attached to the side of the first heat conduction layer away from the LED display screen.

[0006] The area of the second heat conduction layer is larger than that of the first heat conduction layer to completely cover the first heat conduction layer. A recessed groove is formed on one side of the second heat conduction layer.

[0007] In a possible implementation, the thickness of the first heat conduction layer is in the range of 0.3-0.5mm.

[0008] In a possible implementation, the material of the first heat conduction layer is heat-conducting silicone grease.

[0009] In a possible implementation, the recessed groove is formed on one side of the length of the second heat conduction layer.

[0010] In a possible implementation, the thickness of the second heat conduction layer is in the range of 0.3-1.0mm.

[0011] In a possible implementation, the second heat conduction layer is made of copper foil.

[0012] Another aspect of the present application provides a light display device, comprising: an LED display screen and a heat dissipation structure used in a smart cup.

[0013] The LED display screen is in a curved surface structure, and the first heat conduction layer is attached to the back of the LED display screen.

[0014] Beneficial effects: The first heat conduction layer is a heat conduction medium, and is attached between the LED display screen and the second heat conduction layer to effectively fill the small gap therebetween, so as to ensure that the heat can be quickly and effectively transferred. The second heat conduction layer is tightly attached to the surface of the first heat conduction layer, and is used to further disperse the heat. The area of the second heat conduction layer is greater than that of the first heat conduction layer and completely covers the first heat conduction layer, so that the heat on the first heat conduction layer can be evenly dispersed to a larger area, effectively reducing the temperature of the LED display screen. The present application quickly conducts and disperses the heat out of the LED display screen in a double-layer heat conduction manner, and can ensure that the heat is quickly and evenly conducted and dispersed. When the LED display screen works stably for a long time, the performance will not be affected due to local overheating, and the surface temperature of the LED display screen can be controlled within 40℃, thereby prolonging the service life of the LED lamp beads.

[0025] In addition, in order to better illustrate the present application, a large number of specific details are given in the specific embodiments below. Those skilled in the art should understand that without certain specific details, the present application can also be implemented. In some examples, methods, means, elements and circuits familiar to those skilled in the art are not described in detail, in order to highlight the main idea of the present application.

[0026] Figure 1 An exploded view of a light display device according to an embodiment of the present application is shown; Figure 2 A main structure view of a light display device according to an embodiment of the present application is shown; Figure 3 A main structure view of a first heat-conducting layer according to an embodiment of the present application is shown; Figure 4 A main structure view of a second heat-conducting layer according to an embodiment of the present application is shown. As Figure 1As shown, the heat dissipation structure for the intelligent water cup is suitable for dissipating heat for the LED display screen 300 in the intelligent water cup, and comprises a first heat conduction layer 100 and a second heat conduction layer 200. The first heat conduction layer 100 and the second heat conduction layer 200 are both in a curved surface structure. The first heat conduction layer 100 is located in the middle of the LED display screen 300 and the second heat conduction layer 200. One side of the first heat conduction layer 100 is suitable for being attached to the back side of the LED display screen 300. One side of the second heat conduction layer 200 is attached to the side of the first heat conduction layer 100 away from the LED display screen 300. The area of the second heat conduction layer 200 is larger than that of the first heat conduction layer 100 to completely cover the first heat conduction layer 100. A gap 210 is formed on one side of the second heat conduction layer 200.

[0027] Here, it should be noted that the first heat conduction layer 100 is a heat conduction medium, which can effectively fill the small gap between the LED display screen 300 and the second heat conduction layer 200, and ensure that the heat can be quickly and effectively transmitted. The second heat conduction layer 200 is closely attached to the surface of the first heat conduction layer 100, which is used to further disperse heat. The area of the second heat conduction layer 200 is larger than that of the first heat conduction layer 100 and completely covers the first heat conduction layer 100, which can uniformly disperse the heat on the first heat conduction layer 100 to a larger area, effectively reducing the temperature of the LED display screen 300. Since the LED lamp beads 320 generate a large amount of heat, the traditional fan cooling cannot effectively dissipate the heat from the display panel in a short time, resulting in a high temperature of the LED display screen, affecting its display effect and service life, and unable to ensure uniform heat distribution. Local overheating may adversely affect the stability of the LED lamp beads 320. The present application adopts a double-layer heat conduction mode to quickly conduct heat away from the LED display screen 300, and can ensure rapid and uniform heat conduction and dispersion. The LED display screen 300 will not be affected in performance due to local overheating when working for a long time, and the surface temperature of the LED display screen 300 can be controlled within 40℃, prolonging the service life of the LED lamp beads 320 and improving the safety of the product during human-computer interaction, avoiding user discomfort caused by touching the overheated surface.

[0028] In a possible implementation, the main body of the first heat conduction layer 100 is in a quadrilateral sheet structure.

[0029] In a possible implementation, the thickness of the first heat conduction layer 100 is in the range of 0.3-0.5mm. Preferably, the optimal thickness of the first heat conduction layer 100 is 0.3mm.

[0030] In a possible implementation, the material of the first heat-conductive layer 100 is heat-conductive silicone grease. It should be noted that the heat-conductive coefficient of the heat-conductive silicone grease is generally between 0.8-3.5 W / m·K, which has very good heat-conductive performance and plays a superior effect on heat transfer of the LED display screen 300.

[0031] In a possible implementation, the main body of the second heat-conductive layer 200 is in a quadrilateral sheet structure, and the accommodation slot 210 is arranged on one side of the body of the second heat-conductive layer 200. As shown in Figure 4 The one side of the body of the second heat-conductive layer 200 is provided with the accommodation slot 210, and the accommodation slot 210 is in a rectangular groove structure; the arrangement of the accommodation slot 210 is suitable for improving the dismounting convenience of the second heat-conductive layer 200 and the LED display screen 300. Preferably, the length of the accommodation slot 210 is 13 mm; and the width of the accommodation slot 210 is 15 mm.

[0032] In a possible implementation, the thickness of the second heat-conductive layer 200 is in a range of 0.3-1.0 mm. Preferably, the optimal thickness of the second heat-conductive layer 200 is 0.5 mm.

[0033] In a possible implementation, the second heat-conductive layer 200 is made of copper foil or aluminum material, and preferably the second heat-conductive layer 200 is made of copper foil.

[0034] A light display device, comprising: an LED display screen 300 and a heat dissipation structure used in a smart water cup; the LED display screen 300 is in a curved surface structure, and the first heat-conductive layer 100 is attached to the back side of the LED display screen 300. It should be noted that the bending degrees of the LED display screen 300, the first heat-conductive layer 100 and the second heat-conductive layer 200 are the same, and need to be adapted to the bending degree of the sidewall of the smart water cup, so that the LED display screen 300, the first heat-conductive layer 100 and the second heat-conductive layer 200 are completely attached to each other, and the heat-conductive effect is ensured.

[0035] In a possible implementation, the LED display screen 300 comprises: an FPC soft board 310 and two or more LED lamp beads 320; the two or more LED lamp beads 320 are arranged in an array on one side of the FPC soft board 310. Further, each LED lamp bead 320 is attached to the FPC soft board 310 through an SMT patch process.

[0036] In a possible implementation, one side of the FPC soft board 310 protrudes to form a hand holding portion 330, and the hand holding portion 330 is opposite to the accommodation slot 210 of the second heat conduction layer 200. It should be noted that when the LED display screen 300 needs to be maintained, the LED display screen 300 needs to be detached from the first heat conduction layer 100 and the second heat conduction layer 200. Since the LED display screen 300, the first heat conduction layer 100 and the second heat conduction layer 200 are firmly attached, in order to facilitate the removal of the LED display screen 300, the hand holding portion 330 is arranged on one side of the FPC soft board 310, and the hand holding portion 330 is opposite to the accommodation slot 210 of the second heat conduction layer 200. Thus, the LED display screen 300 can be removed by the hand holding portion 330.

[0037] During the overall assembly process, the first heat conduction layer 100 is coated on the back of the FPC soft board 310 of the LED display screen 300; and then the second heat conduction layer 200 is attached to the back of the first heat conduction layer 100.

[0038] The above has described the embodiments of the present application, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments.
