Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Specific examples are given below.

[0025] See also Figures 1 to 8In the embodiment of the utility model, a heat dissipation liquid crystal display module comprises a housing 1, a liquid crystal display 2, an auxiliary heat dissipation mechanism 3, a dustproof mechanism 4 and an iron block 5.

An auxiliary heat dissipation mechanism 3 for dissipating heat for the integrated circuit board 201 is installed in the housing 1. The auxiliary heat dissipation mechanism 3 comprises: a liquid storage box 301, a semi- Conductive cooling sheet 302, pump body 303, U-shaped tube 304, hose 305, inlet tube 306 and return tube 307, the liquid storage box 301 is fixed in the housing 1, water is stored in the liquid storage box 301, a plurality of semiconductor cooling sheets 302 are installed on the liquid storage box 301 (the cooling end of the semiconductor cooling sheet 302 is in contact with the liquid storage box 301), the hot end of the semiconductor cooling sheet 302 is installed with a heat dissipation fin 3021, the semiconductor cooling sheet 302 and the heat dissipation fin 3021 are both located on the outside of the housing 1, and the semiconductor cooling sheet 302 is connected to the heat dissipation fin 3021 through the heat dissipation fin 3021. The heat at the hot end of the conductor cooling sheet 302 is dissipated to ensure the continuous cooling effect of the semiconductor cooling sheet 302. The number of the U-shaped tubes 304 is multiple, and every two adjacent U-shaped tubes 304 are connected by a hose 305. The U-shaped tubes 304 are installed on the integrated circuit board 201 (fixed by glue). The multiple U-shaped tubes 304 are connected by the hose 305 so that when the U-shaped tubes 304 are fixed to the integrated circuit board 201, the position of each U-shaped tube 304 can be adjusted so that the U-shaped tubes 304 avoid the integrated circuit board 201. The liquid storage box 301 has raised electronic components so that the U-shaped tube 304 and the integrated circuit board 201 can fit better together.

The liquid storage box 301, the heat dissipation fins 3021 and the U-shaped tube 304 are all made of aluminum alloy, so that they have good thermal conductivity and are light in weight.

[0026] The dust-proof mechanism 4 comprises: a dust filter 401, a magnetic block 402 and a pull rod 403. The dust filter 401 is installed in the ventilation and heat dissipation slot 101. A magnetic block 402 is fixed on both sides of the dust filter 401. Two iron blocks 5 for the magnetic block 402 to absorb are fixed on the bottom of the casing 1. Two pull rods 403 are installed in the dust filter 401. When in use, air enters and exits the casing 1 from the ventilation and heat dissipation slot 101, and the heat in the casing 1 is taken away by the air flow. The air entering the casing 1 is filtered by the dust filter 401. After a period of use, the dust filter 401 is pulled downward by the pull rod 403, and then the dust filter 401 is cleaned.

[0027] Working principle: When the heat dissipation LCD display module is in use, air enters and exits the casing 1 from the ventilation and heat dissipation slots 101, takes away the heat in the casing 1 through the air flow, and filters the air entering the casing 1 through the dust filter 401. At the same time, the water in the liquid storage box 301 is cooled by the semiconductor refrigeration sheet 302, and the cold water is transported to the U-shaped tube 304 through the pump body 303. The heat on the integrated circuit board 201 is taken away by the U-shaped tube 304, and the water flow after absorbing heat flows back to the liquid storage box 301 through the reflux pipe 307, so as to be circulated and used, so as to better dissipate the heat of the integrated circuit board 201 and the LCD display 2.
