Description

Technical Field

[0001] The invention relates to the field of ro-ro passenger ships, and in particular to a ventilation and heat dissipation system for a giant LED screen on a ro-ro passenger ship. Background Art

[0002] Ro-Ro passenger ships are usually equipped with giant LED screens in the passenger leisure area, which will play non-stop during the operation of the ship and generate heat continuously. Due to its large size and close to the hull bulkhead, a lot of heat will be gathered behind the giant LED screen.

[0003] Conventional ships do not have such huge LED screens, and their air conditioning and ventilation systems only provide fresh and return air in the entire space where the LED screen is located. If this solution is also adopted in the passenger leisure area of ​​the ro-pax ship, heat will accumulate in the back area of ​​the LED giant screen, affecting the performance of the equipment, and at the same time, some heat will spread to the passenger leisure area, reducing comfort. Summary of the invention

[0004] The present invention aims to provide a ventilation and heat dissipation system for a giant LED screen on a ro-ro passenger ship to solve the above technical problems. To this end, the specific technical solutions adopted by the present invention are as follows:

[0006] Furthermore, there are two ventilation and heat dissipation units, which work independently, serve as backup for each other, and are isolated by an electric wind damper.

[0007] Furthermore, corresponding silencers are installed on the air supply duct and the air return duct.

[0008] Furthermore, corresponding air regulating doors are installed on the air supply duct and the air return duct to adjust the air volume.

[0009] Furthermore, the number of the air supply ducts is one more than the number of the air return ducts, and each of the air return ducts is located between two of the air supply ducts.

[0010] Furthermore, the opening of the air supply head of the outermost air supply duct faces inward, the opening of the air supply head of the outermost air supply duct in the middle faces both sides, and the opening of the return air head of the return air duct faces both sides.

[0011] The present invention adopts the above technical solution, which has the beneficial effect of forming air convection in the space behind the LED giant screen, taking away the heat generated by the LED giant screen, achieving good ventilation and heat dissipation effects, and ensuring the comfort of the passenger leisure area.

[0014] Figure 2 yes Figure 1 The schematic diagram of the working principle of the passenger and vehicle ship LED giant screen ventilation and cooling system is shown. DETAILED DESCRIPTION

[0015] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0016] like Figure 1 and 2As shown, a ventilation and heat dissipation system for a passenger ro-ro ship LED giant screen may include multiple air supply pipes 1, multiple return air 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 pipe 1 and the return air pipe 2 are staggered and evenly arranged under the ceiling, extending downward behind the LED giant screen 100, and are respectively connected to the air outlet and return air outlet of the ventilation radiator 31. Among them, the return air head 21 of the return air pipe 2 is close to the top of the LED giant screen 100, and the air supply head 11 of the air supply pipe 1 is close to the bottom of the LED giant screen 100. This arrangement is conducive to the downward movement of cold air and the upward movement of hot air, forming air convection in the space behind the LED giant screen, taking away the heat generated by the LED giant screen, and achieving good ventilation and heat dissipation effects. The two flow paths of the cooler 32 are respectively connected to the ventilation radiator 31 and the external cooling water system fluid. 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 form a temperature control loop to control the cooling water flow of the ventilation radiator 31, thereby controlling the ventilation temperature.

[0017] In this embodiment, there are two ventilation and heat dissipation units 3, which work independently and serve as backup for each other, and are isolated by electric dampers 4. One ventilation and heat dissipation unit 3 can meet the normal use and heat dissipation of the LED giant screen, and work at 50% load in daily operation. When one unit needs maintenance, the remaining one works at full load.

[0018] Preferably, corresponding silencers 5 are installed on all air supply ducts 1 and return air ducts 2 to absorb the noise generated by the wind flow and the fan of the ventilation radiator 31 to prevent the noise from affecting the comfort of the passenger leisure area.

[0019] In this embodiment, corresponding air dampers 6 are installed on all air supply ducts 1 and return air ducts 2 for adjusting the air volume of fresh air and return air to improve heat dissipation efficiency.

[0020] In the illustrated embodiment, the number of supply air ducts 1 is one more than the number of return air ducts 2, and each return air duct 2 is located between two supply air ducts. The opening of the supply air head 11 of the outermost supply air duct 1 faces inward, and the opening of the supply air head 11 of the outermost supply air duct 1 in the middle faces both sides, and the opening of the return air head 21 of the return air duct 2 faces both sides. Therefore, the fresh air flows out from the supply air head 11 toward the return air duct 2, and then flows upward, carrying the heat of the LED giant screen through the return air head 21 into the return air duct 2 to achieve heat dissipation. The airflow path is as follows: Figure 2 shown.

[0021] The following is a brief description of the working principle of the ventilation and heat dissipation system of the passenger and vehicle ship LED giant screen of the present invention. The external cooling water system flows through the cooler 32, and the cooling water inside the ventilation radiator 31 is cooled by heat exchange. The temperature sensor 33 detects the ventilation temperature of the ventilation radiator 31, and controls the internal cooling water flow through the regulating valve 34, thereby controlling the ventilation temperature. The flow of fresh air and heat dissipation return air is adjusted by the air damper 6, and the noise generated by the wind flow and the fan of the ventilation radiator 31 is absorbed by the muffler 5, so that the wind flow is evenly passed through the air supply pipe 1 to the air supply head 11, and flows through the return air pipe 2 through the return air head 21 to return to the ventilation and heat dissipation unit 3, forming an internal circulation.

[0022] The present invention has the following advantages:

[0023] 1. Independent internal circulation system, not affected by external temperature, and does not affect the external temperature at the same time.

[0024] 2. The ventilation and heat dissipation units serve as backup for each other. When one of them fails, the backup can be achieved by adjusting the electric damper.

[0025] 3. The ventilation and heat dissipation cycle is formed behind the LED giant screen, with high heat exchange efficiency.

[0026] 4. Equipped with temperature sensor and regulating valve to automatically adjust the temperature with high degree of automation.

[0027] 5. Equipped with a silencer, it has good noise reduction effect and high comfort.

[0028] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
