[0026] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The following combination Figure 1-Figure 3 The utility model describes a cooling tower and an air inlet volume regulating device thereof.

[0028] This embodiment provides a cooling tower air inlet volume regulating device, such as Figure 1 As shown, it includes: an air inlet channel 1, a first fan 2, a wind shield 3 and a driving rod 4.

[0029] Among them, the outlet end of the air inlet channel 1 is used to communicate with the cooling tower; the first fan 2 is arranged at the air inlet end of the air inlet channel 1; the wind shield 3 is arranged in the air inlet channel 1, and the wind shield 3 can be slidably connected with the air inlet channel 1 along the first direction. An outlet for the wind shield 3 to pass through is provided on one side of the air inlet channel 1, and one end of the driving rod 4 extends into the air inlet channel 1 and is connected with the wind shield 3. The air inlet channel 1 has a connecting groove 5 along the first direction, and the driving rod 4 is located in the connecting groove 5 and can drive the wind shield 3 to move along the first direction. The first direction is the width direction of the air inlet channel 1, that is, the wind shield 3 can move left and right.

[0030] By adopting the above scheme, the cooling tower air inlet volume regulating device can control the air volume entering the cooling tower by moving the position of the wind shield 3. By controlling the air volume entering the cooling tower, it can be ensured that the cooling tower always maintains a stable inlet and outlet water temperature difference, which is crucial to maintaining the stable operation of the cooling system and helps to avoid equipment failure or performance degradation due to water temperature fluctuations.

[0031] In some embodiments, a slide groove 7 is provided in the air inlet channel 1 along the first direction, and a slider 8 is provided on the wind shield 3, and the slider 8 is adapted to the slide groove 7. Figure 1 As shown, the air inlet channel 1 is in the shape of a cube, and a slide groove 7 can be opened on the top plate of the air inlet channel 1 along the first direction, and a slider 8 is correspondingly provided on the top of the wind shield 3. The slider 8 slides with the slide groove 7 to realize the movement of the wind shield 3 along the first direction in the air inlet channel 1 to adjust the size of the air outlet connecting the air inlet channel 1 with the cooling tower; of course, a slide groove 7 can also be opened on the bottom plate of the air inlet channel 1 along the first direction, and a slider 8 can be provided on the bottom of the wind shield 3 to realize the sliding connection between the wind shield 3 and the air inlet channel 1.

[0032] Furthermore, at least a second fan 6 is provided at the air inlet end of the air inlet channel 1. By providing at least two fans at the air inlet end of the air inlet channel 1, the air volume entering the cooling tower can be increased. The number of fans to be turned on can be selected according to actual conditions to improve the cooling effect.

[0033] In this embodiment, the driving rod 4 is a threaded rod, and the end of the driving rod 4 located outside the air inlet channel 1 is connected to a fastening nut 9; through the threaded connection between the fastening nut 9 and the threaded rod, the fastening nut 9 can be abutted against the air inlet channel 1 to fix the position of the wind shield 3. In this way, the position of the wind shield 3 can be adjusted by loosening or tightening the nut, and the position of the wind shield 3 after moving can be fixed.

[0034] The present invention also provides a cooling tower. Figure 2-Figure 3As shown, it includes a shell 10, a water supply mechanism and the above-mentioned cooling tower air inlet volume regulating device. The water supply mechanism is connected to the interior of the shell 10 through a drain pipe 13 and is used to supply water to the interior of the shell 10. The outlet end of the air inlet channel 1 of the cooling tower air inlet volume regulating device is connected to the interior of the shell 10.

[0035] With this arrangement, the cooling tower can determine the number of fans to be started according to different air volume requirements. At the same time, by moving the position of the wind shield 3, the air volume entering the casing 10 is controlled to cool the hot water entering the cooling tower and improve the cooling effect.

[0036] In this embodiment, the water supply mechanism includes a water tank 11, a water pump 12 and a nozzle 14. The nozzle 14 is arranged at the top of the shell 10, and multiple nozzles can be provided. The water tank 11 is arranged on the outside of the shell 10 for accommodating hot water discharged from related systems or equipment. The water suction port of the water pump 12 is connected to the water tank 11 through a suction pipe, and the water outlet of the water pump 12 is connected to the first end of the drain pipe 13. The second end of the drain pipe 13 extends into the shell 10 and is connected to the nozzle 14.

[0037] With this arrangement, the water pump 12 draws the hot water from the water tank 11 and discharges it into the drain pipe 13. The drain pipe 13 sprays the water in the form of water droplets through the nozzle 14. Compared with the water flow, the dispersed water droplets can come into contact with the air more fully, thereby increasing the cooling range and the cooling speed.

[0038] Furthermore, the coil 15 is further included. One end of the coil 15 is connected to the drain pipe 13 , and the other end of the coil 15 is connected to the nozzle 14 . The coil 15 is disposed inside the housing 10 .

[0039] With such an arrangement, the coil 15 can increase the flow time of the water in the housing 10, ensuring that the heat has more time to be transferred from the water to the air, thereby improving the efficiency of the heat exchange and achieving better cooling performance.

[0040] In some embodiments, a third fan 16 is disposed on the top of the housing 10 , and the third fan 16 is disposed above the nozzle 14 to further improve the cooling effect on the hot water.

[0041] In this embodiment, a water reservoir 17 and a filler 18 are provided in the housing 10 . The water reservoir 17 is provided at the bottom of the housing 10 , and the filler 18 is provided between the nozzle 14 and the water reservoir 17 .

[0042] With this arrangement, the water sprayed from the nozzle 14 passes through the filler 18, which can slow down the flow rate of the water, allowing the water flow to stay on the filler 18 for a longer time. This design ensures that heat has more time to be transferred from the water to the air, thereby improving the efficiency of heat exchange, significantly increasing the contact area between water and air, and improving the cooling effect of the hot water provided by the water tank 11, finally achieving the purpose of cooling, and flowing into the water reservoir 17.

[0043] Optionally, the outlet end of the air inlet channel 1 is located between the filler 18 and the water reservoir 17, so that the water flow is initially cooled after passing through the filler 18, and then heat exchanges with the wind provided by the first fan 2 and / or the second fan 6 to improve the cooling effect.

[0044] The working process of the present invention is as follows: when cooling is required, hot water is first drained into the water tank 11, the hot water in the water tank 11 is pumped out by the water pump 12, and discharged into the coil 15 through the drain pipe 13. The coil 15 is set longer, which can increase the flow distance and flow time of the water flow in the shell 10, thereby improving the cooling performance. Several nozzles 14 set at one end of the coil 15 can drip water in the form of water droplets. The dripping water droplets come into contact with the air sent into the air inlet channel 1, and then pass through the filler 18 to complete the cooling. The cooled water droplets are collected in the water reservoir 17, and then can be discharged to the outside and recycled again.

[0045] Among them, the number of fans started in the air inlet channel 1 can be determined according to needs. The first fan 2 and / or the second fan 6 provide blowing air into the shell 10. The fastening nut 9 is loosened, and the wind shield 3 is driven to move left and right by the driving rod 4. The wind shield 3 that moves left and right can control the amount of air entering the shell 10. It is easy to adjust, simple to operate, and highly efficient.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
