The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1 and 2, the LED large screen ventilation and heat dissipation system for a ro-ro passenger ship may include a plurality of air supply pipes 1, a plurality of air return pipes 2, and two ventilation and heat dissipation units 3. Each ventilation and heat dissipation unit 3 includes a ventilation radiator 31, a cooler 32, a temperature sensor 33, and a regulating valve 34. The air supply pipes 1 and the air return pipes 2 are uniformly arranged below the ceiling in a staggered manner, extend downwards behind the LED giant screen 100 and are respectively communicated with the air outlet and the air return inlet of the ventilation radiator 31. Wherein, the return air head 21 of the return air pipe 2 is close to the upper part of the LED huge screen 100, and the air supply head 11 of the air supply pipe 1 is close to the lower part of the LED huge screen 100. This arrangement does benefit to cold air down, and hot-air goes upward, forms the air convection in the huge screen rear space of LED, takes away the heat that the huge screen of LED produced, realizes good ventilation radiating effect. The two flow paths of the cooler 32 are in fluid communication with the ventilated radiator 31 and the external cooling water system, respectively. The temperature sensor 33 is used to detect the ventilation temperature of the ventilation radiator 31. The regulating valve 34 and the temperature sensor 33 constitute a temperature control circuit to control the flow rate of the cooling water of the ventilation radiator 31, thereby controlling the ventilation temperature.

In this embodiment, the number of the ventilation and heat dissipation units 3 is two, and the two units work independently and are mutually standby and separated by the electric air brake 4. One ventilation and heat dissipation unit 3 can meet the normal use heat dissipation of the LED large screen, and the daily work load is 50%. When one needs maintenance, it is operated by the remaining one at full load.

Preferably, all the air supply pipes 1 and the air return pipes 2 are provided with corresponding silencers 5 to absorb the noise generated by the fan of the ventilation radiator 31 and the air flow, so as to avoid the noise from influencing the comfort level of the leisure area of the passengers.

In this embodiment, all air supply pipes 1 and air return pipes 2 are provided with corresponding air adjusting doors 6 for adjusting the air volume of the fresh air and the air return to improve the heat dissipation efficiency.

The following briefly explains the working principle of the LED large screen ventilation and heat dissipation system of the rolling passenger ship of the present invention, the external cooling water system flows through the cooler 33, and cools down the cooling water inside the ventilation and heat dissipation device 31 through heat exchange. The temperature sensor 33 detects the ventilation temperature of the ventilation radiator 31, and controls the flow rate of the internal cooling water by the regulating valve 34, thereby controlling the ventilation temperature. The flow of the fresh air and the heat dissipation return air is adjusted through the air adjusting door 6, the noise generated by the air flow and the fan of the ventilation radiator 31 is absorbed through the silencer 5, the air flow uniformly reaches the air supply head 11 through the air supply pipe 1, and the air flow returns to the ventilation and heat dissipation unit 3 through the air return pipe 2 through the air return head 21, so that internal circulation is formed.
