Technical Field

[0001] This utility model belongs to the field of cooling tower technology, and in particular relates to a closed cooling tower with easily detachable heat exchange coils. Background Technology

[0002] Closed-circuit cooling towers, as a highly efficient and energy-saving cooling device, are widely used in industrial refrigeration, central air conditioning, power electronics, and many other fields. Their core heat exchange component—the heat exchange coil—is prone to scaling on its outer wall due to water vapor evaporation during long-term operation, and deposits may also form in the internal flow channels due to water quality issues. These factors significantly reduce heat exchange efficiency and increase energy consumption.

[0003] Currently, most closed-circuit cooling towers on the market require the use of large tools for partial disassembly and lifting of the heat exchange coils as a whole when cleaning, descaling, or repairing / replacing them. This maintenance method is not only labor-intensive but also poses certain safety risks. Utility Model Content

Detailed Implementation

[0016] To better understand the purpose, structure, and function of this utility model, a clear and complete description of this utility model will be provided below in conjunction with the accompanying drawings.

[0017] like Figures 1-4 The diagram shows a closed-loop cooling tower with easily detachable heat exchange coils, comprising: a tower body 1, wherein the interior of the tower body 1 is provided with, from top to bottom, a fan 2, a water collector 3, a spray pipe 4, a heat exchange coil 5, packing 6, and a water collection tray 7; an external spray pump 8 is provided, which is connected to the spray pipe 4 via a pipe; louvers 18 are provided on the side wall of the tower body 1; and an inlet 16 and an outlet 17 are provided on the front side of the tower body 1, which pass through its front wall and are respectively connected to both ends of the heat exchange coil 5, with the inlet 16 located below the outlet 17. The above structure is based on the structure of closed-loop cooling towers in the prior art and will not be described in detail here.

[0018] The lower part of the heat exchange coil 5 is equipped with a fixing frame 9, which is fixed to the heat exchange coil 5 by bolts. The bottom of the fixing frame 9 has multiple fixing plates 9-1, which serve to support the heat exchange coil 5 and allow spray liquid to reach the lower part of the tower body 1. A detachable rear wall plate (not shown in the figure) is provided on the rear wall of the tower body 1 corresponding to the heat exchange coil 5. Specifically, the rear wall of the tower body 1 and the rear wall plate are detachably connected by bolts, and an elastic seal is provided at the connection between the rear wall plate and the rear wall of the tower body 1. The elastic seal is used to seal the gap between the rear wall and the rear wall plate, and its material is rubber. When maintenance is required, simply remove the bolts and the elastic seal to remove the rear wall plate. The entire heat exchange coil 5 can then be pulled out of the tower body 1 through the spacious operating space at the rear of the tower body 1, eliminating the need for complex internal or top disassembly. Cleaning, inspecting, or replacing the heat exchange coil 5 is simpler and faster, greatly reducing maintenance difficulty, time, and cost.

[0019] To facilitate the removal of the heat exchange coil 5 and the mounting bracket 9, a pull ring 15 is provided on the front wall of the mounting bracket 9. This provides a point of leverage, allowing the entire mounting bracket 9 and the heat exchange coil 5 to be removed by pulling the pull ring 15. The heat exchange coil 5 can then be cleaned and maintained. To reduce downtime, the heat exchange coil 5 can be removed from the mounting bracket 9 for cleaning and maintenance. At the same time, a clean new heat exchange coil 5 can be installed on the mounting bracket 9. The mounting bracket 9 with the new heat exchange coil 5 is then installed inside the tower body 1.

[0020] A second guide assembly is provided between the front wall of the tower body 1 and the rear wall of the fixing frame 9; mounting brackets 10 are provided inside the two side walls of the tower body 1 corresponding to the heat exchange coil 5. The mounting brackets 10 contact the fixing frame 9, and a first guide assembly is provided between the mounting brackets 10 and the side walls of the fixing frame 9. The first guide assembly performs preliminary lateral coarse positioning when the fixing frame 9 and the heat exchange coil 5 are pushed back for installation, guiding the fixing frame 9 smoothly into the predetermined installation area; the second guide assembly achieves precise longitudinal and lateral positioning and installation through conical surface engagement in the final stage of heat exchange coil 5 installation, ensuring the accuracy and reliability of the assembly.

[0021] To facilitate the removal of the fixing bracket 9 from the mounting bracket 10, pulleys are provided on the bottom of both sides of the fixing bracket 9; the mounting bracket 10 is provided with a sliding groove 10-1 that cooperates with the pulleys.

[0022] In this embodiment, the first guide assembly includes a guide plate 11 disposed on the mounting bracket 10. The guide plate 11 is inclined upwards and away from the middle of the tower body 1, and is separate from the side wall of the tower body 1. The guide plates 11 on the two mounting brackets 10 are symmetrically arranged, and the line connecting their extension directions forms a V-shape. To facilitate fixing the mounting bracket 10 to the inner wall of the tower body 1, the mounting bracket 10 is provided with a connecting plate 10-2. The connecting plate 10-2 is provided with a connecting hole 10-3, which is used to connect to the side wall of the tower body 1 by bolts.

[0023] That is, the mounting frame 10 includes a slide 10-1 and a connecting plate 10-2. The side wall of the slide 10-1 is connected to the connecting plate 10-2 by a plate. The connecting plate 10-2 is connected to the inside of the tower body 1. A guide plate 11 is provided on the upper part of the wall where the slide 10-1 is connected to the plate. The guide plate 11 extends upward toward the connecting plate 10-2. The guide plate 11 is integrally formed with the side wall of the slide 10-1.

[0024] In this embodiment, the second guide component includes guide posts 12 disposed on both sides of the rear wall of the fixed frame 9, and guide blocks 13 disposed on the front wall of the tower body 1 and connected to the two guide posts 12 respectively. The diameter of the guide post 12 gradually decreases from its connection with the rear wall of the fixing frame 9 toward the front wall of the tower body 1, forming a truncated cone or a cone shape; the guide block 13 is provided with a guide groove 14 that is adapted to the guide post 12.

[0025] When the fixing frame 9 is pushed back into the tower body 1, after the rough positioning by the guide plate 11, the fixing frame 9 is roughly in place. At this time, the conical tips of the guide columns 12 installed on both sides of the rear wall of the fixing frame 9 begin to approach the inlet of the guide groove 14 of the guide block 13 located on the front wall of the tower body 1. Even if the fixing frame 9 still has a deviation of a few millimeters in the left-right or up-down direction, the conical head of the guide column 12 will not be blocked by the guide block 13, but will touch the conical slope of the inlet of the guide block 13. As the fixing frame 9 continues to move into the tower body 1, the conical surface of the guide column 12 will contact and slide with the conical surface of the guide groove 14, forcing the fixing frame 9 to move in the opposite direction of the slight deviation. Until the guide column 12 and the guide groove 14 are fully engaged, the centering installation is achieved. Furthermore, the tight fit between the guide column 12 and the guide groove 14 also helps to resist the lateral displacement caused by vibration during equipment operation, thus increasing the overall stability. The inlet 16 and outlet 17 of the heat exchange coil 5 on the fixed frame 9 are perfectly aligned with the pipe interface on the front wall of the tower body 1, allowing for easy connection of flanges or quick couplings.

[0026] This device enables rapid on-site removal and extraction of the heat exchange coil 5 without the need for complete disassembly or return to the factory, greatly shortening maintenance time and reducing maintenance costs. Furthermore, the two-stage positioning system using the first and second guide components ensures the alignment accuracy of the heat exchange coil 5 during reinstallation, avoiding repeated manual adjustments and guaranteeing sealing and spraying effectiveness.

[0027] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
