Air inlets are located around the lower section of the tower body, and a water collection tank is located below each air inlet. Spray pipes are vertically arranged within the tower body, close to the inner wall. Heat exchange coils are vertically arranged inside the spray pipes. First nozzles are distributed on the spray pipes, angled upwards towards the heat exchange coils; second nozzles are distributed on the inner bottom surface of the water collection tank. This invention, by changing the spray direction, increases the contact area and contact time between the heat exchange coils and the spray water and air, thereby increasing the cooling effect of the water spray system on the air inlet, and can solve the problem of insufficient cooling efficiency in existing closed-loop cooling towers.

The lower side of the solenoid valve 12 is provided with an exhaust fan 13 and a mounting plate 14 in sequence. A movable plate 16 nested within the tower body 1 is provided on the lower outer side of the dustproof net 3.

This facilitates the purpose of circulating spray cooling and prevents dust and impurities from entering the closed cooling tower by passing through the inner side of the dustproof net 3. The dustproof net 3 is fitted with a waterproof and breathable membrane 4 that is attached and fixed to the tower 1 to prevent the sprayed water from splashing, thus facilitating the high efficiency and energy saving of the closed cooling tower. like Figure 2 and Figure 3 During the use of this closed cooling tower, a packing layer 18 is installed inside the tower body 1 through the waterproof and breathable membrane 4.
