However, for display screens used outdoors for a long time, since most of their internal components are electronic components, the requirements for dust and water protection are relatively high. Some display screen casings have good sealing performance, but correspondingly, their heat dissipation performance will decrease. Therefore, there is a need for a fully enclosed display screen that can both ensure dust and water protection effects and take into account heat dissipation performance. Content of the Utility Model

A cavity surrounding plate is installed at the bottom of the back side of the fan blade power box. A heat dissipation cavity is enclosed between the cavity surrounding plate and the protective back plate. An internal cavity pipe is installed on the fan blade power box, and the inlet pipe orifice of the internal cavity pipe extends into the heat dissipation cavity. A refrigeration hole is opened on the protective back plate, and a refrigeration installation frame is installed in the refrigeration hole. A semiconductor refrigerator is installed in the refrigeration installation frame.

[0006] Further, the semiconductor cooling end of the semiconductor refrigerator is arranged in the electronic component cavity, and the semiconductor heating end of the semiconductor refrigerator is arranged in the heat dissipation cavity.

[0007] Further, a control board assembly is installed in the electronic component cavity through a board rack, and a temperature sensor is installed on the cavity wall of the electronic component cavity.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0016] The present invention will be further described below with reference to the drawings:

[0017] As Figure 1 - Figure 2 shown, a display screen module with good heat dissipation performance is composed of a display screen ring frame 1 and a fan blade power box 2;

[0018] The fan blade power box 2 is installed on the top of the display screen ring frame 1. The display screen body 9 and the protective back plate 4 are respectively installed and fixed on the front and back sides of the frame body of the display screen ring frame 1. The protective back plate 4 is a fully enclosed back plate, which has better dust and water resistance. The display screen ring frame 1, the display screen body 9 and the protective back plate 4 enclose a component cavity;

A multi-contact heat dissipation groove column 3 is installed in the heat conduction holes. The multi-contact heat dissipation groove column 3 is made of a heat conductive material, facilitating the heat in the component cavity to be conducted out. One end of the multi-contact heat dissipation groove column 3 extends into the component cavity and is provided with a number of annular multi-contact deep grooves 16. The setting of the multi-contact deep grooves 16 increases the contact area between the multi-contact heat dissipation groove column 3 and the hot gas in the component cavity, thereby accelerating heat dissipation;

[0020] At the bottom of the back side of the fan blade power box 2, a cavity surrounding plate 5 is installed. A heat dissipation cavity 12 is enclosed between the cavity surrounding plate 5 and the protective backplane 4. Only the bottom air inlet is left on the cavity surrounding plate 5 to facilitate the influx of air flow. An inner cavity pipe 11 is installed on the fan blade power box 2, and the inlet pipe orifice of the inner cavity pipe 11 extends into the heat dissipation cavity 12;

[0021] On the protective backplane 4, a refrigeration hole is provided. A refrigeration mounting frame 8 is installed in the refrigeration hole. A semiconductor refrigerator is installed in the refrigeration mounting frame 8. It is a small refrigeration structure, normally in a non-working state, and starts when the temperature is too high to avoid damage to the internal components caused by excessive temperature.

[0022] As Figure 1 - Figure 2 shown, the present utility model also discloses the following multiple more optimized specific structures:

[0023] The semiconductor refrigeration cold end 14 of the semiconductor refrigerator is arranged in the component cavity, and the semiconductor refrigeration hot end 13 of the semiconductor refrigerator is arranged in the heat dissipation cavity 12.

[0024] A control board assembly 7 is installed in the component cavity through a board rack 6. A temperature sensor 17 is installed on the cavity wall of the component cavity, which is used to detect the temperature in the component cavity.

[0025] A fan assembly is installed in the fan blade power box 2, which is composed of a fan blade, a motor driving the fan blade, and a frame body for fixing the motor and installing the fan blade. It is a disclosed structure and will not be further described here. A front screen inclined pipe 10 is installed at the bottom of the front side of the fan blade power box 2, and the front screen inclined pipe 10 is used to blow air towards the display screen body 9 to reduce dust adhesion.

[0026] One end of the multi-contact heat dissipation groove column 3 extends into the heat dissipation cavity 12 and is provided with a number of air guiding vertical channels 15, increasing the area between the external air flow and the multi-contact heat dissipation groove column 3 and increasing heat dissipation.

[0027] As Figure 1 - Figure 2The display module with good heat dissipation effect shown realizes the gas flow in the heat dissipation cavity 12 mainly through the fan blade assembly of the fan blade power box 2, conducts heat exchange inside and outside the component cavity through the multi-contact heat dissipation groove columns 3, and conducts heat conduction and dissipation quickly through the multi-contact deep grooves 16 and the air guiding vertical channels 15, realizing the rapid heat dissipation of the fully enclosed component cavity, with good heat dissipation effect. At the same time, a small semiconductor refrigerator is equipped to avoid component damage caused by overheating, and the safety factor is high.
