Description

Technical Field

[0001] This utility model relates to the field of air cooler technology, specifically a rotatable tube bundle air cooler. Background Technology

[0002] An air cooler, also known as an air cooler, is one of the most widely used heat exchange devices for condensation and cooling in petrochemical and oil and gas processing production. An air cooler typically consists of main components such as tube bundles, tube boxes, fans, louvers, and a frame.

[0003] In the prior art, since the multiple tube bundles of an air cooler are usually fixedly installed, the air cooling effect of the fan on the air cooler is not uniform enough, resulting in poor air cooling effect of the air cooler. Therefore, we have introduced a rotatable tube bundle air cooler. Utility Model Content

[0004] The purpose of this invention is to provide a rotatable tube bundle air cooler that significantly improves the air cooling effect and the air cooling uniformity of the air cooler, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rotatable tube bundle air cooler includes a base. Two housings are fixed to the upper ends of the base via support rods. An inlet pipe and an outlet pipe are respectively connected to opposite sides of the two housings. Hollow columns are rotatably mounted inside the housings via rolling bearings. One end of each hollow column extends to the outside of the housing. Multiple tube bundles are connected between the two hollow columns. A motor is mounted on the top of the base. Fan blades are fixed to the output end of the motor. A rotating shaft is rotatably mounted on the upper end of the base. A first transmission mechanism is provided on the upper end of the rotating shaft. A second transmission mechanism is provided between the rotating shaft and the motor.

[0007] As a further embodiment of this utility model, the first transmission mechanism includes a first bevel gear and a second bevel gear. The first bevel gear is fixedly mounted on the upper end of the rotating shaft, and the second bevel gear is fixedly mounted on the outer side of the hollow column. The first bevel gear and the second bevel gear are meshed together.

[0008] As a further embodiment of this utility model, the second transmission mechanism includes two pulleys, which are respectively fixedly mounted on the rotating shaft and the output shaft of the motor, and a belt is provided between the two pulleys for transmission.

[0009] As a further embodiment of this invention, the plurality of tube bundles are configured in a U-shape.

[0010] As a further embodiment of this invention, the rolling bearing is configured as a sealed bearing.

[0011] As a further embodiment of this utility model, positioning blocks are rotatably provided on both sides of the shaft wall of the rotating shaft, and the positioning blocks are fixedly connected to the support rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This rotatable tube bundle air cooler comprises a support rod, base, outlet pipe, shell, tube bundles, inlet pipe, fan blades, motor, shaft, belt, pulley, positioning block, first bevel gear, second bevel gear, and hollow column. Water flows in through the inlet pipe, enters the shell, then flows through multiple tube bundles into another shell and out through the outlet pipe. The motor is started, and its output drives the fan blades to rotate, cooling the multiple tube bundles. The motor's output shaft, via pulley and belt, drives the shaft to rotate, which in turn drives the first bevel gear. The first bevel gear drives the meshing second bevel gear, which in turn drives the hollow column, thus rotating the multiple tube bundles. The interaction between the fan blades and the rotatable tube bundles significantly improves the air cooling effect and uniformity of the air cooler. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution:

[0021] A rotatable tube bundle air cooler includes a base 2. Both sides of the upper end of the base 2 are fixed with housings 4 via support rods 1. Water inlet pipes 6 and outlet pipes 3 are respectively connected to opposite sides of the two housings 4. Hollow columns 15 are rotatably mounted inside the housings 4 via rolling bearings. The opposite ends of the two hollow columns 15 extend to the outside of the housings 4. Multiple tube bundles 5 are connected between the two hollow columns 15. The multiple tube bundles 5 are U-shaped, and the tube bundles 5 can increase the air cooling effect. A motor 8 is mounted on the top of the base 2. The motor 8 is electrically connected to an external power source via a control switch. Fan blades 7 are fixedly mounted on the output end of the motor 8. A rotating shaft 9 is rotatably mounted on the upper end of the base 2. A first transmission mechanism is provided on the upper end of the rotating shaft 9, and a second transmission mechanism is provided between the rotating shaft 9 and the motor 8.

[0022] Reference Figure 4 The first transmission mechanism includes a first bevel gear 13 and a second bevel gear 14. The first bevel gear 13 is fixedly mounted on the upper end of the rotating shaft 9, and the second bevel gear 14 is fixedly mounted on the outside of the hollow column 15. The first bevel gear 13 and the second bevel gear 14 are meshed together.

[0023] Reference Figure 3 The second transmission mechanism includes two pulleys 11, which are fixedly mounted on the rotating shaft 9 and the output shaft of the motor 8, respectively, and a belt 10 is provided between the two pulleys 11 for transmission.

[0024] The rolling bearing is set as a sealed bearing, which can improve the sealing between the hollow column 15 and the housing 4.

[0025] Positioning blocks 12 are rotatably provided on both sides of the shaft wall of the rotating shaft 9. The positioning blocks 12 are fixedly connected to the support rod 1. The positioning blocks 12 can provide positioning for the rotating shaft 9, thereby ensuring that the first bevel gear 13 and the second bevel gear 14 are always meshed.

[0026] In use, water is introduced through the inlet pipe 6, and the water in the inlet pipe 6 enters the housing 4, then enters another housing 4 through multiple tube bundles 5 and is discharged through the outlet pipe 3. The motor 8 is started, and the output end of the motor 8 drives the fan blades 7 to rotate. The fan blades 7 cool the multiple tube bundles 5. The output shaft of the motor 8 drives the rotating shaft 9 to rotate through the pulley 11 and the belt 10. The rotating shaft 9 drives the first bevel gear 13 to rotate, the first bevel gear 13 drives the meshing second bevel gear 14 to rotate, the second bevel gear 14 drives the hollow column 15 to rotate, and thus drives the multiple tube bundles 5 to rotate. Through the cooperation of the fan blades 7 and the multiple rotatable tube bundles 5, the air cooling effect of the air cooler is greatly improved, and the air cooling uniformity of the air cooler is also improved.
