A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0029] like Figure 1-3 As shown, a cooling tower preferably used in an embodiment of the utility model comprises a tower body 1, a spray mechanism 2, a filler 7 and an air inlet regulating mechanism 3; the tower body 1 has a containing cavity 11, and a side wall of the tower body 1 is provided with an air inlet 12 connected to the containing cavity 11; the spray mechanism 2 comprises a water pipe 21 and a spray head 22, the spray head 22 is connected to the water pipe 21 and is located in the containing cavity 11; the filler 7 is arranged in the containing cavity 11 and is located below the spray head 22; the air inlet regulating mechanism comprises a driving motor 31, a rotating shaft 32 and a rolling curtain 33, the driving motor 31 is connected to the rotating shaft 32 and can drive the rotating shaft 32 to rotate around the central axis of the rotating shaft 32, the rotating shaft 32 is located above the air inlet 12, the air inlet 12 is located between the filler 7 and the rolling curtain 33, and the upper end of the rolling curtain 33 is connected to the rotating shaft 32.

[0030] Based on this technical solution, when the cooling tower is operating with a large water volume, the driving motor 31 can drive the rotating shaft 32 to rotate and wind the rolling curtain 33, so as to drive the rolling curtain 33 to rise to a first preset height, so that the projection of the rolling curtain 33 in the horizontal direction and the projection of the air inlet 12 in the horizontal direction do not overlap, so that the air inlet 12 can be in a fully open state and have a maximum air inlet area; when the cooling tower is operating with a small water volume, the driving motor 31 can drive the rotating shaft 32 to rotate and unfold the rolling curtain 33, so that the rolling curtain 33 can be lowered to a second preset height, so that the projection of the rolling curtain 33 in the horizontal direction and the projection of the air inlet 12 in the horizontal opening partially overlap, so that the rolling curtain 33 can partially block the air inlet 12 to reduce the air inlet area of ​​the air inlet 12, thereby reducing the air intake through the water-free area of ​​the filler 7, reducing the waste of air intake volume, and improving the cooling efficiency of the unit air volume of the cooling tower. Therefore, the cooling tower provided by the present invention can adjust the air inlet area of ​​the air inlet 12 by driving the motor 31, the rotating shaft 32 and the roller shutter 33 to reduce the waste of the air volume and improve the cooling efficiency of the cooling tower per unit air volume.

[0031] The cooling tower has a horizontal direction X and a vertical direction Z, and the horizontal direction X and the vertical direction Z are perpendicular to each other.

[0032] The filler 7 can be directly arranged in the accommodating cavity 11 by stacking, or can be indirectly arranged in the accommodating cavity 11 by auxiliary components such as a mesh box, which is not limited here.

[0033] The driving motor 31 can be directly mounted on the outer wall of the tower body 1 to be disposed outside the tower body 1 , or can be mounted on a mounting frame located outside the tower body 1 to be disposed outside the tower body 1 , which is not limited here.

[0034] Optionally, the number of the shower heads 22 is one or more.

[0035] In this embodiment, there are multiple shower heads 22 .

[0036] See also Figure 2 The lower end of the rolling curtain 33 is provided with an air distribution groove 331 which is concave upward and penetrates the rolling curtain 33 along the thickness direction of the rolling curtain 33. The rolling curtain 33 has a first vertical center line 30, and the air distribution groove 331 has a second vertical center line. The first vertical center line 30 and the second vertical center line coincide. Since the cooling water is mainly distributed in the middle and bottom of the filler 7 when the cooling tower is running with a small amount of water, the air distribution groove 331 extending upward from the lower end of the rolling curtain 33 can match the distribution shape of the cooling water in the filler 7 when the water volume is small, so that the incoming air can better pass through the water distribution area of ​​the filler 7, which helps to reduce the waste of the incoming air volume and improve the cooling efficiency of the cooling tower per unit air volume.

[0037] The air distribution channel 331 includes a top wall 3311, a first side wall 3312, and a second side wall 3313. The first side wall 3312 and the second side wall 3313 are respectively connected to the two ends of the top wall 3311. The first side wall 3312 extends obliquely from top to bottom and away from the second vertical center line, and the second side wall 3313 extends obliquely from top to bottom and away from the second vertical center line. The top wall 3311, the first side wall 3312, and the second side wall 3313 are used to enclose the air distribution channel 331, so that the air distribution channel 331 can be similar to a trumpet-shaped structure with a small top and a large bottom, so that the air inlet shape of the air inlet can be better matched with the distribution shape of the cooling water in the filler 7 when the water volume is small, which helps to further reduce the waste of air intake and further improve the cooling efficiency of the cooling tower per unit air volume.

[0038] The air inlet adjustment mechanism 3 further includes a guide rail 34, which is arranged on the side of the rolling curtain 33 away from the tower body 1, and the guide rail 34 is in contact with the side of the rolling curtain 33 facing the guide rail 34. The use of the guide rail 34 can play a guiding and limiting role in the lifting and lowering process of the rolling curtain 33, which helps to better adjust the air inlet area of ​​the air inlet 12 through the lifting and lowering of the rolling curtain 33, thereby further reducing the waste of the air intake volume and further improving the cooling efficiency of the cooling tower per unit air volume.

[0039] In this embodiment, the rolling curtain 33 is disposed between the air inlet 12 and the guide rail 34 .

[0040] In some other embodiments, the guide rail 34 may also be disposed between the air inlet 12 and the roller blind 33 .

[0041] In this embodiment, there are two guide rails 34, the roller blind 33 has a first vertical center line 30, and the two guide rails 34 are symmetrically distributed about the first vertical center line 30. The two guide rails 34 symmetrically distributed about the first vertical center line 30 can better play a limiting and guiding role in the lifting process of the roller blind 33.

[0042] In some other embodiments, the number of guide rails 34 may be one, three, four, five, or any other number and may be distributed in any preset order, which is not limited here.

[0043] The cooling tower also includes a controller 4, and the drive motor 31 is electrically connected to the controller 4; the spray mechanism 2 also includes a flow meter 23, which is installed on the water pipe 21 and electrically connected to the controller 4. The flow meter 23 and the controller 4 are used so that the controller 4 can control the drive motor 31 to drive the roller shutter 33 to rise and fall according to the water inlet flow measured by the flow meter 23 of the water pipe 21, thereby realizing the function of automatically adjusting the height of the roller shutter 33 according to the water inlet flow. For example, when the water inlet flow of the water pipe 21 is the maximum, the controller 4 can drive the roller shutter 33 to rise to a first preset height through the drive motor 31, so that the air inlet 12 is in a fully open state and has the maximum air inlet area; when the water flow of the cooling tower decreases, the controller 4 drives the roller shutter 33 to descend to a second preset height through the drive motor 31, thereby reducing the air inlet area of ​​the air inlet 12 and increasing the air inlet wind speed of the air inlet 12.

[0044] Preferably, the cooling tower further comprises a rain shield 5, which is arranged above the air inlet adjustment mechanism 3. The rain shield 5 can shield and protect the driving motor 31, the rotating shaft 32 and the rolling curtain 33 from rain.

[0045] In this embodiment, the rain shield 5 is directly connected to the outer wall of the tower body 1 so as to be arranged above the air inlet adjustment mechanism 3 .

[0046] In some other embodiments, the rain shield 5 can also be arranged above the air inlet adjustment mechanism 3 through any supporting components such as a mounting frame, a mounting rod, etc., which is not limited here.

[0047] The cooling tower further includes a surface cooler 6 , which is disposed in the accommodating cavity 11 and between the spray head 22 and the filler 7 .

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
