Waterproof heat-dissipation LED display screen

Abstract

The invention relates to an LED display screen, in particular to a waterproof heat-dissipation LED display screen. The waterproof heat-dissipation LED display screen comprises an LED light source assembly (10), a heat sink and a waterproof outer cover (50), wherein the heat sink comprises a radiation heat-dissipation layer (20) and a heat exchange heat-dissipation layer (40); the radiation heat-dissipation layer (20) and the heat exchange heat-dissipation layer (4) are adhered to each other through heat-conduction adhesive; the heat exchange heat-dissipation layer (40) comprises a first heat-dissipation bottom plate (41) adhered to the radiation heat-dissipation layer (20) and a plurality of heat-conduction water tubes (43) which are perpendicular to the first heat-dissipation bottom plate (41); the heat-conduction water tubes (43) contain water in a sealed manner; and a heat-conduction bar (431) which is fixedly connected with the first heat-dissipation bottom plate (41) is sealed in the heat-conduction water tubes (43) and penetrates out of the first heat-dissipation bottom plate (41). The heat-conduction bar can transfer heat into water in time, the heat is dissipated to the outside by the water, and heat-dissipation stability and heat-dissipation speed are considered; and by the independent heat-conduction water tubes, other water tubes are not affected when a single heat-conduction water tube leaks water, and heat dissipation can be maintained stably.

Description

technical field [0001] The invention relates to an LED display screen, in particular to a waterproof and heat dissipation LED display screen. Background technique [0002] With the development of science and technology, the application of LED display screen or flat panel display is more and more widely. LED is a solid material that can convert electric energy into light energy. Long and other characteristics, it is gradually replacing traditional light sources and has been widely used in many fields in production and life. [0003] With the application of LED display screens, LED display screens tend to be high-end and display detailed development. The heat dissipation problem has always been an important factor restricting the use of LED screens. If the LED display screen does not solve the heat dissipation problem, it will not only affect its normal use.

[0003] With the application of LED display screens, LED display screens tend to be high-end and display detailed development. The heat dissipation problem has always been an important factor restricting the use of LED screens. If the LED display screen does not solve the heat dissipation problem, it will not only affect its normal use. Performance, in severe cases, it will cause the heat of the display screen to be too high to dissipate, damage the internal chip, and greatly shorten the effective service life of the LED display screen

[0004] There are two main cooling methods for LED displays today, one is air convection cooling, but its cooling effect is often not ideal; the other is outdoor full-color LED large screen heat exchange cooling, which can only achieve partial cooling Once the heat is generated, it will have a great impact on the performance stability, color uniformity and life of the LED display; and in the heat exchange and heat dissipation method, water is a common heat transfer carrier , water leakage often occurs due to careless use, which not only affects the cooling effect of the display screen, but also affects the service life of the display screen
