Embodiment Construction

[0026] The technical solution provided by the present invention is: using the principle of liquid cooling, filling the flat metal tube of the liquid circuit with cooling liquid, closely attaching the metal tube to the metal backboard, and starting the electric hydraulic pump when the backlight is on, so that the cooling The liquid circulates in the liquid circuit formed by the flat metal tube, transfers the heat of the LED light source area to the rest of the backplane, reduces the temperature of the LED light source area, and makes the temperature of the entire metal backplane even, so that the liquid crystal in the liquid crystal display device The temperature of the panel is uniform.

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments describe...

Abstract

The invention relates to a liquid-cooled radiating side backlight module and a radiating method thereof. The side backlight module comprises a light-emitting diode (LED) light source and a metal back plate, wherein the metal back plate covers the LED light source and comprises an LED light source area corresponding to the LED light source; and a liquid-cooling device is arranged on the metal back plate. When backlight is switched on, the liquid-cooling device disperses the heat of the LED light source area to the other areas of the back plate, so that the faults of the LED light source area are reduced, and the temperature of the overall metal back plate is uniform.

Description

technical field [0001] The invention relates to a side-type backlight module, in particular to a side-type backlight module using liquid cooling for heat dissipation and a heat dissipation method thereof. Background technique [0002] Liquid crystal display devices have gradually replaced traditional CRT display devices and become the mainstream of the display market due to their characteristics of low radiation, low power consumption, thin thickness and light weight. [0003] At present, the liquid crystal display device adopting the side-type LED backlight module brings users an ultra-thin experience, and also conforms to the development trend of energy saving and environmental protection, and gradually becomes a hot spot in the market. However, the temperature of the LED light strip area in the side LED backlight module is very high, while the temperature of other parts of the backlight module is relatively low, which brings two problems: one is that the temperature of th...
