There is a large height difference between the air inlet and the air outlet, so it is not easy for the air to flow in and out, and the temperature of the intake air can be lower. The heat exchange power of the countercurrent tower is high. The air inlet louvers of the closed cooling tower can be arranged along the circumference or around it, so the air inlet is more uniform and the cooling effect is good. On the external dimensions, the diameter of the circular tower is larger than that of the square tower with the same function, and the side length is also larger. For these reasons, the application of the circular tower that is constrained by the area is affected.

When the direct cooling beam of the closed cooling tower fill block has a small support, the supporting beam should have a small width, and the structure and ventilation resistance should be small. The beam spacing should be equipped with a simple support lining plan. When the grid is supported, the span of the grid simply supported and the span of the support beam should be together, and the grid corrosion function should be compatible with the fill. The fill function and thermal function should be combined with the general comments of the fan function, and the cooling capacity should be selected under the same planning conditions. For film packaging, when the combination of the same type of paper and the height are different, it should be calculated. When the planned temperature difference is large, a larger piece should be selected.

Closed cooling tower is a new type of cooling equipment that can not only lower the temperature of cooling water, but also maintain the innocence of water quality. Together, it has multiple functions, strong environmental habits, simple structure, small size, small footprint, and cooling. High efficiency, simple connecting pipes, small engineering amount, convenient equipment repair and cleaning, water and electricity saving (low head and large flow of spray water pump, small motor power, just on the unit), low operating cost, can cool high temperature water, Oil, liquid gasification, etc., fire prevention and other characteristics.
