Description

A high-efficient heat dissipation face guard for LED display screen

Technical Field

The utility model relates to a LED display screen technical field, more specifically say, it relates to a high-efficient heat dissipation face guard for LED display screen.

Background

The LED display screen is a novel information display medium which is rapidly developed in the world in recent years. The LED display panel displays pictures such as graphics and characters by utilizing a dot matrix module formed by semiconductor Light Emitting Diodes (LEDs), and has the characteristics of high brightness, long service life, large visual angle, wide color gamut, modular structure, strong environmental adaptability and the like, so that the LED display panel rapidly grows into a mainstream product of flat panel display in short decades. Because the photoelectric conversion efficiency of the LED is only about 20% -30%, most of the electric energy input to the LED lamp beads can be converted into heat, and in addition, the LED lamp beads used by the LED display screen are huge in number, so that the LED lamp beads generate heat to become a main source of the heat of the LED display screen. Generally, the temperature of the screen body of the LED display screen is very high when the LED display screen works, and the temperature of the outdoor LED display screen is further increased under the irradiation of sunlight. It is known that the carrier concentration inside the semiconductor is greatly affected by temperature, and the service life of the LED lamp is reduced when the LED lamp is operated in a high temperature environment for a long time. In addition, under a high-temperature environment, the brightness of the red, green and blue LED lamps is not only reduced, but also the brightness attenuation values are different, which causes the overall display effect of the LED display screen to be reduced. Therefore, improving the heat dissipation capability of the LED display screen is an important research content in the LED display field.

The traditional method for radiating the LED display screen is mainly to install a fan inside a box body. The method is that the fan is used to rotate to accelerate the flow of hot air and quickly discharge the hot air in the box body to the outside of the box body, thereby keeping the working temperature of the display screen in a normal interval. However, this method of heat dissipation has several drawbacks: firstly, the heat dissipation efficiency is low; secondly, the rotating noise of the fan is larger; thirdly, the clearance of fan has not made between the box inside and the external environment blockked, and when the fan was out of work, ash layer and moisture can enter into inside the box through the fan clearance to influence the life of LED display screen circuit.

Water-cooling heat dissipation has been widely used in recent years as an efficient heat dissipation method. Compared with fan heat dissipation, the LED water-cooling heat dissipation has great advantages, such as simple installation, high heat dissipation efficiency, no noise and the like. The LED box body mainly achieves the purpose of heat dissipation by driving water flow to circulate between the interior of the LED box body and the exterior of the LED box body through the water pump. When low-temperature liquid flows to the position near the lamp panel in the LED box body along the pipeline, heat generated on the LED lamp panel is transferred to the liquid to enable the temperature of the liquid to be increased; as the liquid circulates, the liquid absorbing heat flows out to the outside of the case and releases heat, so that the liquid becoming low temperature again participates in the circulation. However, this method adopts a post-heat dissipation manner, that is, heat is dissipated from the side of the lamp panel other than the LED lamp surface, and a large amount of heat generated by the LED lamp surface of the lamp panel cannot be effectively and rapidly released, so that the temperature of the LED lamp surface cannot be effectively reduced.
