[0002] Display components such as liquid crystal TVs and tablet computers are liquid crystal modules, whose status is equivalent to the picture tube in a CRT. Other parts include a power supply circuit, a signal processing circuit, and a housing, etc. The liquid crystal module is mainly divided into a screen and a backlight assembly. The two parts are assembled together but work independently. The principle of liquid crystal display is that the backlight assembly emits uniform surface light, and the light passes through the liquid crystal screen and reaches our eyes. The function of the screen is to process this light by pixels to display images.

[0003] Since the resolution of liquid crystal displays is getting higher and higher, the brightness requirement for the backlight module is also getting higher and higher.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] Please refer to Figures 1-3 , the present invention provides a technical solution: an LED liquid crystal display heat dissipation module, including a frame 1, a liquid crystal display component is installed inside the frame 1, and a rear cover 3 is installed on the back side of the frame 1.

[0030] A heat dissipation chamber 4 is formed between the rear cover 3 and the liquid crystal display component, and a contact heat dissipation component 2 is installed in the heat dissipation chamber 4;

[0031] The contact heat dissipation component 2 includes a heat conducting sheet 201, a refrigeration sheet 202 and a small exhaust fan 203;

[0032] The inner side of the rear cover 3 is fixedly connected with a heat conducting sheet 201. Among them, the heat conducting sheet 201 is a copper thin sheet or an aluminum thin sheet. It has good heat conduction characteristics. One side of the heat conducting sheet 201 is fixedly connected with a refrigeration sheet 202. Among them, the refrigeration sheet 202 is a semiconductor refrigeration sheet. The semiconductor refrigeration sheet has a refrigerating surface and a heating surface. The air suction port of the small exhaust fan 203 faces the heating surface of the refrigeration sheet 202, and the refrigerating surface of the refrigeration sheet 202 faces the heat conducting sheet 201.

[0033] One side of the rear cover 3 is fixedly connected with a sealed fan base 204. The sealed fan base 204 is in a communicating state with the inside of the heat dissipation chamber 4, and the small exhaust fan 203 is installed in the sealed fan base 204.

[0034] In a further solution, the air outlet of the small exhaust fan 203 is connected to an air guiding channel 205; the air guiding channel 205 is an air duct 206 and an air guiding port 207 located on both sides of the small exhaust fan 203. The air duct 206 and the air guiding port 207 are connected, and the air guiding port 207 faces both sides of the outer edge of the frame 1.

[0035] An air inlet 208 is provided at the side of the rear cover 3 that communicates with the heat dissipation chamber 4. The air inlet 208 and the air guiding port 207 are not arranged in the same direction to prevent hot air from re-entering the heat dissipation chamber 4.

[0036] During operation, the heat generated by the liquid crystal display module is conducted to the heat conducting sheet 201. After the refrigeration chip 206 is powered on, it cools on one side and heats on the other side. The cooling surface is closely attached to the heat conducting sheet 201, and the heat will be neutralized at the heat conducting sheet 201, and the accumulated heat will be consumed. The heat generated by the heating surface enters the heat dissipation chamber 4, and this part of the heat needs to be exported in time, otherwise it will affect the working effect of the refrigeration chip 206. By the rotation of the small exhaust fan 208, the heat in the heat dissipation chamber 4 is extracted and enters the air guiding channel 205, and then enters the air guiding port 207 through the air duct 206, and the heat is exported through the air guiding port 207. External air enters through the air inlet 208 on the side of the heat dissipation chamber 4 to form the entire hot air cooling cycle.
