[0040] The working principle of the device is as follows:

[0041] The push-pull window body 2 is arranged on the civil structure of the upper air inlet of the cooling tower, and a plurality of push-pull window bodies 2 are arranged on both sides of the cooling tower. In the season with high temperature in summer, the push-pull window body 2 is pulled by the handle, and under the action of force, the pulley 4 slides to the left in the slide rail 3, thereby driving the flat plate to slide to the left. Figure 1 As shown in the figure, the flat plate reaches the A area, the upper air inlet of the cooling tower is closed, and the cold air enters from the lower air inlet, thereby meeting the cooling demand and satisfying the production.

[0042] In the cold winter months, when the temperature is low, the user manually pulls the handle to slide the window 2. Under the force, the pulley 4 slides to the right in the slide rail 3, thereby causing the flat plate to slide to the right. At this point, the flat plate reaches... Figure 1 As shown in area B, the upper air inlet of area A is exposed. At this time, some cold air enters from the upper air inlet and exchanges heat with the lower hot air to achieve the effect of defogging and water saving. Some cold air enters from the lower air inlet to participate in cooling and achieve the cooling requirement.

[0043] Meanwhile, the opening area of ​​the upper air inlet is larger than the area of ​​the maintenance door. This sliding window 2 can replace the original maintenance door. When maintenance is required, slide the sliding window 2 to open the upper air inlet. People can enter the cooling tower from the upper air inlet for maintenance, thereby eliminating the maintenance door, simplifying the cooling tower components and saving costs.

[0044] In view of the shortcomings and drawbacks of the current sliding window 2 for defogging and water-saving cooling towers, this paper proposes to modify and improve it, and develop a new sliding window 2 with a simple structure, cost-saving, and effective performance. It also incorporates the function of an inspection door, thereby eliminating the original inspection door structure, further simplifying the structure, saving costs, and improving efficiency.
