The display device of the present application will be described in detail with reference to specific embodiments.
Example one
Fig. 1 is a schematic structural diagram of a display device according to an embodiment of the present application. The display device includes: the display module assembly comprises a display module assembly 1 and a heat dissipation module assembly 2, wherein the display module assembly 1 is positioned on one side of the heat dissipation module assembly 2; the heat dissipation module 2 is used for dissipating heat of the display module 1. The heat dissipation module 2 comprises a first heat dissipation plate 21 and a second heat dissipation plate 22 which are parallel to the display module 1, and the first heat dissipation plate 21 and the second heat dissipation plate 22 are combined to form a cavity structure with two open ends. The side surface of one side of the heat radiation module 2 is provided with an air inlet 201, the side surface of the other side is provided with an air outlet 202, and the cavity forms a heat radiation air duct.
The display module 1 is provided with a display surface and a back surface, the display surface is provided with a plurality of Mini-LED light-emitting units or Micro-LED light-emitting units which are arranged in a dot matrix manner, and the back surface is attached to the heat dissipation module 2. The heat generated by the display module 1 during operation is conducted to the heat dissipation module 2 through the back surface of the display module 1, and then is discharged through the heat dissipation air duct.
In order to facilitate heat conduction for heat dissipation, the display module 1 and the heat dissipation module 2 are bonded through heat-conducting glue, the heat-conducting glue is a glue material with better heat-conducting property, and specific materials are not limited.
Furthermore, metal particles are uniformly doped in the heat-conducting glue, and the metal has good heat-conducting property, so that the heat-conducting property of the heat-conducting glue can be further enhanced, and the heat on one side of the display module 1 can be rapidly conducted to the heat dissipation module 2.
Further, in order to enhance the heat dissipation performance of the heat dissipation module 2, the material of the heat dissipation module 2 is a metal material, for example, an aluminum alloy plate or the like may be used for the first heat dissipation plate 21 and the second heat dissipation plate 22.
In one embodiment, the first heat dissipation plate 21 and the second heat dissipation plate 22 may be integrally formed by molding or the like, and the first heat dissipation plate 21 and the second heat dissipation plate 22 are an integral structure, which may simplify the manufacturing process.
In an embodiment, the shapes of the air inlet 201 and the air outlet 202 may be set to be one or a combination of an oval shape, a circular shape, a triangular shape and a rectangular shape, and the positions of the air inlet 201 and the air outlet 202 may also be set according to the actual heat dissipation requirement of the display module 1.
As shown in fig. 1, an air inlet 201 is disposed at a lower portion of the heat dissipation module 2, an air outlet 202 is disposed at an upper portion of the heat dissipation module 2, and the heat dissipation module 2 is hollow to form a heat dissipation air duct, so that a chimney structure is formed inside the heat dissipation module 2. Most of the heat of the display module 1 is dissipated in one direction, that is, the heat of the display module 1 is mainly dissipated through the back surface, so that most of the heat of the display module 1 is dissipated to the heat dissipation module 2 and the inside of the heat dissipation module 2, the density of the air with high temperature inside the heat dissipation module 2 is reduced and increased, and the air is exhausted from the upper air outlet 202, at this time, a negative pressure region is formed in the original place of the low-density air, and then the fresh air with low external temperature and high density and specific gravity of the heat dissipation module 2 is sucked into the heat dissipation air duct from the air inlet 201 at the lower part of the heat dissipation module 2. Thus, heat is easily and rapidly carried away by the hot air in a convection method by the chimney structure. Therefore, the technical effect of accelerating the heat dissipation of the display module 1 is achieved.
In order to further achieve a better heat dissipation effect, in the present embodiment, heat dissipation fins 23 are disposed on a side surface of the first heat dissipation plate 21 facing the second heat dissipation plate 22, and the heat dissipation fins 23 divide the heat dissipation air duct into a plurality of heat dissipation sub-air ducts.
Fig. 2 is a schematic structural diagram of a first heat dissipation plate according to an embodiment of the present application. The heat dissipation fins 23 of the first heat dissipation plate 21 may be integrally formed with the body of the first heat dissipation plate, or the heat dissipation fins 23 may be separately attached to the first heat dissipation plate 21. The heat dissipation fins 23 of two adjacent rows and/or two adjacent columns are distributed in a staggered manner, so that air moving from bottom to top can enter the plurality of heat dissipation sub-air ducts from the gap between two adjacent heat dissipation fins 23 and then continue to move upwards under the action of buoyancy. The heat dissipation fins 23 can perform a shunting function, so that hot air is uniformly distributed in the heat dissipation air duct, and the formation of a thermal boundary layer is delayed. The arrangement of the heat dissipation fins 23 increases the disturbance of flowing air in the heat dissipation air channel, and the flowing state of hot air in the heat dissipation air channel is changed from unidirectional to multidirectional, so that the air flow rate between the heat dissipation fins 23 is improved, and the heat dissipation performance of the heat dissipation module is further enhanced.
Further, the heat dissipation fins 23 are arranged obliquely to the surface of the first heat dissipation plate 21, and an included angle between the heat dissipation fins 23 and the surface of the first heat dissipation plate 21 is 10-80 °. The heat dissipation fins 23 are inclined toward the air outlet 202.
Because the heat dissipation fins 23 are inclined toward the air outlet 202, the resistance of air flowing in the heat dissipation air duct can be reduced, which is helpful for the convection between the air in the heat dissipation air duct and the outside air.
Further, the cross-sectional shape of the heat dissipation fin 23 is one of circular, triangular and rectangular.
Further, the heat dissipation fins 23 have a predetermined distance from the second heat dissipation plate 22 in a direction perpendicular to the second heat dissipation plate 22. Therefore, the shunting function and the air disturbance function of the heat dissipation fins 23 can be realized, and the resistance of the air flowing in the heat dissipation air duct is further reduced, so that the heat dissipation performance of the heat dissipation module 2 is facilitated.
In one embodiment, the distribution density of the heat dissipation fins 23 on the first heat dissipation plate 21 is gradually decreased from the middle area of the first heat dissipation plate 21 to the periphery. Therefore, the heat dissipation fins 23 in the middle area of the first heat dissipation plate 21 can well distribute the heat to the periphery, which is beneficial to dredging the heat in the middle area of the first heat dissipation plate 21, the density of the heat dissipation fins 23 in the periphery area of the first heat dissipation plate 21 is relatively low, the resistance of the air flowing in the heat dissipation air duct is relatively small, and the heat in the heat dissipation air duct can be quickly taken away.
The radiating efficiency of radiating module among the display device of this application receives external environment input heat and display module and generates heat and heat the intensification influence, and the input heat is big more or intensification is higher, and the chimney effect is just stronger, and the radiating effect can be better thereupon. This application need not specially from external input power energy through the special heat dissipation wind channel of design behind the display module, utilizes gas thermal expansion density to reduce the chimney effect of the upwards flow of nature, and the design of rethread heat dissipation wing is reinforceed the air convection and is realized the heat dissipation, need not external input electric energy, the energy saving consumed the festival.
Example two
Fig. 3 is a schematic structural diagram of a display device according to a second embodiment of the present application. The present embodiment is the same/similar to the display device of the first embodiment, except that: the display device of this embodiment is a double-sided display device, and can realize double-sided display, that is, the display module includes the first display module 11 attached to the first heat dissipation plate 21 and the second display module 12 attached to the second heat dissipation plate 22.
The display surfaces of the first display module 11 and the second display module 12 are provided with Mini-LED light emitting units or Micro-LED light emitting units arranged in a dot matrix, and of course, the first display module 11 and the second display module 12 may also be other types of display modules, which is not limited herein.
This embodiment is owing to set up the heat dissipation module that has the chimney effect between two display module assemblies, consequently, can effectively solve the not good problem of display module assembly heat dissipation to promote display module assembly's display effect and life.
