[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the flow of water and air to exchange heat and generate steam. The steam evaporates and takes away the heat to achieve evaporative heat dissipation, convection heat transfer and radiation heat transfer. It dissipates the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature through evaporative heat dissipation to ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower.

[0033] The air inlet window 21 is movably mounted inside the two ends of the cooling box 1 , the fan 22 is fixedly mounted on the surface of the cooling box 1 at the outer end of the air inlet window 21 , and the noise reduction plate 23 is movably mounted inside the cooling box 1 at the other end of the air inlet window 21 .

[0034] The cooling box 1 is square in shape and has an opening at both ends. Two fans 22 are rotatably installed inside the cooling box 1 at the two openings, and the two fans 22 are fixedly installed on the surface of the two openings. The noise reduction plate 23 is rotatably installed at one end of the two air inlet windows 21 close to the interior of the cooling box 1. Many noise reduction sheets are installed inside the noise reduction plate 23, and the air passes between the noise reduction sheets to achieve the effect of noise reduction.

[0035] The air inlet 31 is opened on the inner surface of the cooling box 1 at the top of the noise reduction plate 23 , and the air outlet 32 ​​is opened on the inner surface of the cooling box 1 at the bottom of the noise reduction plate 23 .

[0036] There are two air inlets 31 and two air outlets 32. A plate is fixedly connected to the center of the bottom of the cooling box 1, dividing the bottom of the cooling box 1 into two parts. The two air inlets 31 and the two air outlets 32 are respectively opened at the upper and lower ends of the two grooves. When the air inlet 31 is opened, the air flowing into the interior of the cooling box 1 can flow into the top of the cooling box 1 through the air inlet 31.

[0037] The sealing plate 41 is movably embedded in the cooling box 1 at the upper and lower ends of the noise reduction plate 23 , and the connecting port 42 is opened on the surface of the sealing plate 41 .

[0038] There are two sealing components 4, which are respectively arranged inside the upper and lower ends of the groove at the bottom, and two connecting ports 42 are opened on the surface of each sealing plate 41.
