The following embodiments are only used to more clearly illustrate the technical solutions of the utility model, so they are only examples and cannot be used to limit the protection scope of the utility model.

[0028] As Figure 1 shown, the high-level water collecting cooling tower includes a tower body 2, a packing 5 is arranged inside the tower body 2, a plurality of water collecting devices 7 are arranged in parallel below the packing 5, the heights of the plurality of water collecting devices 7 are arranged in a gradually decreasing manner from the middle to both sides, a water collecting baffle 10 is fixedly connected obliquely between adjacent water collecting devices 7, and both ends of the water collecting baffle 10 respectively extend above the adjacent two water collecting devices 7.

[0029] Both side walls of the water collecting baffle 10 are hermetically connected to the inner wall of the tower body 2.

[0030] The water collecting device 7 includes a water collecting tank 12 arranged in a V shape, and both ends of the water collecting tank 12 are hermetically and fixedly connected to the inner wall of the tower body 2.

[0031] Pipes can be arranged on the water collecting tank 12 to realize the discharge of the collected water.

[0032] A flow guiding frame is arranged between adjacent water collecting tanks 12.

[0033] The flow guide frame includes an inclined plate 8 fixedly connected to the port of the water collecting tank 12 at the lower part in an inclined manner. A plurality of vertical rods 9 are fixedly connected in parallel at the upper end of the inclined plate 8. The lower end of the vertical rod 9 extends into the water collecting tank above and forms an air inlet flow area through the area between adjacent vertical rods 9.

[0034] Inside the tower body 2, a suspension bracket 11 is fixedly connected corresponding to each water collecting tank 12. The lower end of the suspension bracket 11 extends into the water collecting tank and is fixedly connected to the inner wall of the water collecting tank.

[0035] The water collecting baffle 10 is fixedly connected to the upper surface of the inclined plate 8.

[0036] The lower end of the water collecting baffle 10 is provided with a vertical section extending into the water collecting tank 12, so that after the water collecting baffle 10 blocks the sprayed water, the water flow flows into the water collecting tank 12 along the water collecting baffle 10.

[0037] The outer bottom surface of the water collecting tank 12 is arranged in an arc shape, reducing the resistance and making the air flow in the tower more gentle. Through CFD simulation and testing, the air flow in the tower is made more uniform after the outside air enters the tower from the air inlet 6.

[0038] The tower body 2 is respectively provided with air inlets 6 corresponding to the water collecting devices 7 on both sides.

[0039] Inside the tower body 2, a flow guide plate is fixedly connected in an inclined manner between the upper edge of the air inlet 6 and the adjacent water collecting device 7.

[0040] The flow guide plate is arranged to be inclined downward from the outside to the inside.

[0044] The working principle of this device is as follows:

[0045] In the utility model, the water collecting devices 7 are arranged in sequence from the air inlet 6 to the inner side of the tower body 2. The resistance at the air inlet 6 is adjusted by the change in height, making the flow field in the tower more uniform, increasing the ventilation volume, solving the problem of insufficient air volume participating in heat exchange at the packing 5 on the side far from the air inlet 6 of the single-side air inlet cooling tower, and improving the heat exchange effect;

[0046] The V-shaped water collecting devices 7 are arranged in sequence from low to high at the air inlet 6. Through testing and CFD simulation, it is found that since the height of the V-shaped water collecting devices 7 changes in a stepped manner, the air flow field inside the tower is optimized, making the air flow field inside the tower more uniform, enabling the outside air to enter the inner side of the tower body 2 more easily, allowing the innermost packing 5 to participate in heat exchange, improving the cooling efficiency of the cooling tower, solving the problem of insufficient air volume for heat exchange at the packing 5 on the side far from the air inlet 6 of the single-sided air inlet cooling tower, and enhancing the heat exchange effect. Moreover, the water collecting tank 12 of the V-shaped water collecting device 7 is in a V-like shape, and the bottom is designed to be arc-shaped, which can reduce resistance and air volume loss, making the air flow from the outside to the inside of the tower more gentle, and also playing a role in making the flow field inside the tower uniform.
