LED screen rear heat absorption and heat dissipation device

Abstract

The invention discloses an LED screen rear heat absorption and heat dissipation device which comprises a body and a rotating shaft. Circular bubbles and circular dimples are arranged on both sides ofthe body. The circular bubbles on one side of the body form the circular dimples on the other side of the body. The circular dimples on one side form the circular bubbles on the other side of the body. Through holes penetrating the body are arranged in the center of the circular bubbles and the center of the circular dimples. The circular bubbles and the circular dimples on the same side are alternately arranged in a row of circular bubbles and a row of circular dimples. A heat absorption sheet is arranged on one side in the body, and a heat dissipation sheet is arranged on the other side. A heat conductive material is arranged between the heat absorption sheet and the heat dissipation sheet. According to the invention, a row of circular bubbles and a row of circular dimples are arranged alternately; the problem that the quality of an LED screen is deteriorated, which is caused by the fact that the LED display screen is affected by the external ambient temperature in the prior art, iseffectively avoided; and a better protection effect is realized.

Description

technical field [0001] The invention relates to the technical field of heat absorption and heat dissipation for liquid crystal screens, in particular to a heat absorption and heat dissipation device behind an LED screen. Background technique [0002] With the development of monitors to this day, the consumer-grade field has truly entered the LCD era. LED or LCD TVs are all consumable products, and they are also somewhat delicate electrical equipment. [0003] For LED display screens, since LEDs and ICs are semiconductor devices, they are picky about the conditions of use in the environment, preferably at a room temperature of about 25°C, and their working mechanism is the best. But in fact, an outdoor large screen will be used in different temperature environments. In summer, it may be above 60°C, and in winter, it may be below -20°C. When the manufacturer produces products, it uses 25°C as the test condition to classify different products. , but the actual operating condit...

Problems solved by technology

[0005] Therefore, whether the design of the thermal loop system for ventilation and heat dissipation is good, with the extension of the startup time and the increase of the external temperature, the thermal drift of the components will also increase, resulting in poor image quality and affecting the quality and life of the display screen. Therefore, it is very necessary to design a thermal circuit device for ventilation and heat dissipation that is adapted to environmental influences.
