Description
Technical Field
[0001] This utility model relates to the field of cooling towers, and more specifically, to an energy-saving flow guiding device for cooling towers. Background Technology
[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere to lower the temperature. It utilizes the principle of heat exchange between water and air to generate steam. The steam evaporates and carries away the heat, achieving heat dissipation through evaporation, convection, and radiation. This process dissipates waste heat generated in industrial processes or refrigeration and air conditioning systems to lower the water temperature and ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower.
[0003] A search revealed an existing patent (publication number: CN219064200U) disclosing an energy-saving airflow guiding device for a cooling tower duct, comprising: a cooling tower body, a duct installed at the top of the cooling tower body, an air inlet duct installed at the bottom right end of the cooling tower body, two water inlet pipes installed in the middle of the right end of the cooling tower body, and a frame block installed at the left end of the water inlet pipes. In use, hot air is injected into the cooling tower body through the air inlet pipes, and cold water enters the water pipes from the water inlet pipes. When the fan is turned on, the rising hot air contacts the water pipes, and the water carried by the hot air flows down the water guide channel, landing on the surface of the connecting block and connecting rod, and then in the recovery trough. The inventors discovered the following problems with the existing technology during the development of this utility model:
[0004] Existing energy-saving flow guiding devices for cooling towers inject hot air into the interior of the cooling tower body through an air inlet. However, they do not have a structure for guiding the hot air flow during injection, which reduces the flow rate of the hot air during cooling. Furthermore, the cooling area of the hot air is limited by using water pipes alone, which reduces the cooling effect on the hot air.
[0005] Therefore, an energy-saving flow guiding device for cooling towers is proposed to address the above problems. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an energy-saving flow guiding device for cooling towers to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving airflow guiding device for a cooling tower, comprising an air inlet guiding box, a cooling tower body fixedly mounted on the upper surface of the air inlet guiding box, an air outlet hood fixedly connected to the top of the cooling tower body, a guiding pipe fixedly connected to the upper surface of the air inlet guiding box, an annular support plate fixedly mounted on the inner wall of the cooling tower body, the top of the guiding pipe penetrating the annular support plate and extending above the annular support plate, a cooling plate provided inside the cooling tower body, an absorption plate fixedly mounted on the inner wall of the cooling tower body, a fixing plate fixedly mounted on the inner wall of the air outlet hood, a drive motor fixedly mounted on the upper surface of the fixing plate, a drive rod fixedly mounted on the output end of the drive motor, the bottom end of the drive rod penetrating the absorption plate and the cooling plate in sequence and extending into the interior of the air inlet guiding box, an upper guide vane and a lower guide vane fixedly mounted on the outer surface of the drive rod, and a water inlet assembly provided outside the cooling tower body.
[0008] Preferably, a drain pipe is fixedly connected to the outer surface of the cooling plate, the bottom end of the drain pipe passes through the annular support plate and extends to the bottom of the annular support plate, and a water pump is fixedly installed on the upper surface of the annular support plate.
[0009] Preferably, the water inlet assembly includes a water inlet pipe, one end of which penetrates through the cooling tower body and extends into the interior of the cooling tower body. A solenoid valve is connected to the outer surface of the water inlet pipe, and a water inlet connector is fixedly connected to one end of the water inlet pipe.
[0010] Preferably, the bottom surface of the air intake guide box is fixedly connected to an air intake pipe, and one end of the air intake pipe is fixedly connected to an air intake flange.
[0011] Preferably, the output end of the water pump is fixedly connected to a water injection pipe, the end of the water injection pipe away from the water pump passes through the cooling plate and extends into the interior of the cooling plate, the input end of the water pump is fixedly connected to a water suction pipe, and the bottom end of the water suction pipe passes through the annular support plate and extends below the annular support plate.
[0012] Preferably, two sealed bearings are fixedly embedded on the outer surface of the cooling plate, and the inner rings of the two sealed bearings are fixedly connected to the outer surface of the drive rod.
[0013] Preferably, an ultrasonic water level gauge is fixedly installed on the bottom surface of the annular support plate, and multiple collection holes are opened on the bottom surface of the annular support plate.
[0014] Preferably, an annular guide shroud is fixedly connected to the inner wall of the air intake guide box, the top of the annular guide shroud is fixedly connected to the inner top wall of the air intake guide box, and two sets of fixing blocks are fixedly connected to the inner ring of the cooling tower body, with the side of the two sets of fixing blocks close to each other being fixedly connected to the outer surface of the cooling plate.
[0015] The technical effects and advantages of this utility model are as follows:
[0016] Compared with existing technologies, this energy-saving airflow guiding device for cooling towers uses an inlet airflow guiding box and an annular airflow guiding shroud to guide the inflow of hot air. Furthermore, the drive motor inside the outlet shroud can drive the drive rod, upper guide vane, and lower guide vane to rotate. The rotation of the lower guide vane allows the air to flow upwards evenly and quickly after entering, avoiding the airflow short-circuiting phenomenon in traditional cooling towers. In addition, the circular cooling plate design allows the air to fully contact the cooling plate, improving heat exchange efficiency.
[0017] Compared with existing technologies, this energy-saving airflow guiding device for cooling towers accelerates the exhaust speed of air after heat exchange through the exhaust hood by driving the upper guide vane to rotate via a drive rod. This prevents air from remaining inside the cooling tower body and guides the airflow during exhaust. Furthermore, this airflow guiding device has a bidirectional airflow structure for both intake and exhaust, solving the problem of slow internal flow of hot air injected into the cooling tower body via the intake manifold. It also increases the cooling area for hot air and improves the cooling effect. Attached Figure Description

[0027] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail:
[0028] like Figures 1-5As shown, in a preferred embodiment, a drain pipe 19 is fixedly connected to the outer surface of the cooling tray 10. The bottom end of the drain pipe 19 passes through the annular support plate 18 and extends to the bottom of the annular support plate 18. A water pump 15 is fixedly installed on the upper surface of the annular support plate 18. An air inlet pipe 13 is fixedly connected to the bottom surface of the air inlet guide box 1. One end of the air inlet pipe 13 is fixedly connected to an air inlet flange 14. A water injection pipe 16 is fixedly connected to the output end of the water pump 15. The end of the water injection pipe 16 away from the water pump 15 passes through the cooling tray 10 and extends into the interior of the cooling tray 10. A water pump 17 is fixedly connected to the input end of the water pump 15. The bottom end of the water pump 17 passes through the annular support plate 18 and extends to the bottom of the annular support plate 18. The water inlet assembly 4 includes a water inlet pipe 401. One end of the water inlet pipe 401 passes through the cooling tower body 2 and extends... Extending into the interior of the cooling tower body 2, the outer surface of the water inlet pipe 401 is connected to a solenoid valve 402, and one end of the water inlet pipe 401 is fixedly connected to a water inlet connector 403. Furthermore, through the setting of the water inlet pipe 401 and the water inlet connector 403, water can be supplied to the interior of the cooling tower body 2, and the setting of the solenoid valve 402 can control the water flow. Through the setting of the drain pipe 19, the water after heat exchange can flow downward. With the cooperation of the air inlet pipe 13 and the air inlet flange 14, it can be connected to the external hot air pipeline. Through the cooperation of the water pump 15, the water extraction pipe 17 and the water injection pipe 16, the injected water can be extracted and then injected into the interior of the cooling plate 10 through the water injection pipe 16, so that there is a large amount of cold water inside the cooling plate 10, which is convenient for cooling the hot air.
[0029] like Figures 1-5 As shown, in a preferred embodiment, two sealed bearings 11 are fixedly embedded on the outer surface of the cooling plate 10. The inner rings of the two sealed bearings 11 are fixedly connected to the outer surface of the drive rod 8. The arrangement of the two sealed bearings 11 enables the drive rod 8 to rotate stably, making the rotation of the drive rod 8 more stable. An ultrasonic water level gauge 22 is fixedly installed on the bottom surface of the annular support plate 18. Multiple collection holes 21 are opened on the bottom surface of the annular support plate 18. An annular guide shroud 23 is fixedly connected to the inner wall of the air intake guide box 1. The top of the cooling tower is fixedly connected to the inner top wall of the air intake guide box 1. Two sets of fixing blocks 24 are fixedly connected to the inner ring of the cooling tower body 2. The side of the two sets of fixing blocks 24 that are close to each other are fixedly connected to the outer surface of the cooling plate 10.

The multiple collection holes 21 can collect and guide the water droplets condensed inside the cooling tower body 2. The two sets of fixing blocks 24 can fix and support the cooling plate 10 inside the cooling tower body 2.
[0030] The working process of this utility model is as follows:
[0031] When the cooling tower energy-saving flow guiding device is used later, firstly, outside air enters through the air inlet pipe 13 on the bottom of the air inlet guide box 1. Then, after the air enters the interior of the air inlet guide box 1, it flows upward evenly under the guidance of the annular guide shroud 23. Then, the water inlet component 4 outside the cooling tower body 2 is responsible for supplying water, which allows water to enter the interior of the cooling tower body 2.
[0032] Then, by working with the water pump 15 and the water pipe 17, the injected water can be drawn out and injected into the cooling plate 10 through the water injection pipe 16. Then, by starting the drive motor 7, the drive rod 8, the upper guide vane 9 and the lower guide vane 12 can be rotated. The rotation of the lower guide vane 12 in the air intake guide box 1 can accelerate the upward flow of air, which will make the air fully contact the cooling plate 10 and carry away the heat.
[0033] After the cooling plate 10 absorbs heat, the internal hot water is discharged into the cooling tower body 2 through the drain pipe 19, completing one cooling cycle. The drive rod 8 drives the upper guide vane 9 to rotate, which will cause the air after heat exchange to be discharged through the air outlet hood 3, which can accelerate the discharge speed of the gas after heat exchange.
[0034] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
