Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically a closed-loop cooling tower anti-corrosion heat exchange tube assembly device. Background Technology

[0002] The heat exchange tube assembly is the "heat dissipation skeleton" of a closed-circuit cooling tower and its most crucial component. It is responsible for the primary task of heat transfer. The hot fluid that needs to be cooled flows from the system into one end of the heat exchange tube assembly through the tubes (closed loop). After circulating through the densely packed pipes, the cooled fluid flows out from the other end and returns to the equipment for continued use. At the same time, the cooling tower's spray system sprays cold water evenly onto the outer wall of the heat exchange tube assembly through the tubes (spray evaporation), forming a water film. Driven by a fan, the sprayed water absorbs the heat transferred from the fluid inside the tubes on the tube wall, and some of it evaporates into water vapor, carrying away a large amount of latent heat of vaporization to achieve the heat dissipation process.

[0003] The cooling towers and heat exchanger tube assemblies currently available on the market are usually installed in a fixed manner. When the heat exchanger tube assembly is damaged after long-term use, it cannot be quickly disassembled and reinstalled. Furthermore, since the metal tubes in the heat exchanger tube assembly are in contact with water, scale can easily form on the outside of the metal tubes over time, affecting the heat dissipation effect and preventing automatic cleaning. Utility Model Content

[0004] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a closed-loop cooling tower anti-corrosion heat exchange tube assembly device.

[0005] This utility model is implemented as follows: a closed-loop cooling tower anti-corrosion heat exchange tube assembly is constructed. The assembly includes a cooling tower, a water outlet valve located on the outer side of the bottom end of the cooling tower, an inlet located on the left side of the outer side of the cooling tower, an outlet located on the right side of the outer side of the cooling tower, an exhaust fan installed on the outer side of the cooling tower, a motor fixedly connected to the rear end face of the cooling tower, a limiting groove opened on the inner side wall of the cooling tower, a cover plate covering the upper end face of the cooling tower, a water inlet located at the center of the upper end face of the cover plate, and three nozzles fixedly connected to the lower end face of the cover plate, with the three nozzles communicating with the water inlet.

Two first sliding grooves are provided on the upper and lower sides of the inner side wall of the heat exchange tube assembly. A second sliding groove is provided between the two first sliding grooves on the inner side wall of the heat exchange tube assembly.

[0008] Preferably, the bottom inner surface of the second chute is provided with a toothed groove, the inner side wall of the heat exchange tube assembly is slidably connected to a connecting plate, the heat exchange tube assembly is slidably connected to a frame plate, and the connecting plate is fixedly connected to the frame plate through the first chute via a connecting block. The front end face of the connecting plate is rotatably connected to five cleaning roller brushes, and each cleaning roller brush is located at the upper and lower ends of the metal tube respectively. The heat exchange tube assembly is rotatably connected to a circular plate, and the center of the circular plate is fixedly connected to the column.

[0009] Preferably, the front end face of the circular plate is fixedly connected to a limiting post, and the limiting post is slidably connected to the frame plate.

A long gear is inserted into and rotatably connected to the center of the connecting plate, and the long gear meshes with the tooth groove and the gear. The long gear and the gear are fixedly connected to the cleaning roller brush.

[0010] Preferably, when the U-shaped handle is inserted downwards, its bottom can block and limit the card plate, thereby keeping the card plate in a locked state with the slot.

When cleaning of the metal tubes is required, the motor is turned on to drive the cleaning roller brush to move and rotate, thus cleaning the outer surface of the metal tubes and reducing the accumulation of scale that would affect heat dissipation over long-term use.

[0028] The working principle of the closed-loop cooling tower anti-corrosion heat exchange tube assembly based on Embodiment 1 is as follows:

[0029] First, when using the equipment, connect it to an external power source to provide the necessary power. Then, connect the input pipe and output pipe to the input port 3 and output port 4 respectively, and connect the water supply pipe to the water inlet 9. When it is necessary to install the heat exchange tube assembly 13, use the mobile device to lift the heat exchange tube assembly 13 into the cooling tower 1 through the U-shaped handle 20, so that the interface 150 is connected to the input port 3 and output port 4 respectively. At the same time, the clamping plate 18 is squeezed back into the heat exchange tube assembly 13 by force. By sliding the column 16 and the limiting groove 7 to limit the movement, when the limiting clamping plate 29 is inserted into the groove 17 and the clamping plate 18 is inserted into the slot 11, release the U-shaped handle 20 so that it moves downward with gravity to block and limit the clamping plate 18. This can achieve quick installation and use. Conversely, it can also achieve quick disassembly.

[0030] Secondly, heat dissipation can be achieved simply by spraying water through the nozzle 10 to contact the metal tube 15 in the heat exchange tube assembly 13, and simultaneously turning on the exhaust fan 5 to drive the airflow inside the cooling tower 1.

[0031] Third, when it is necessary to clean the metal tube 15, the motor 6 is turned on to drive the limiting plate 29 to rotate the column 16 through the slot 17, which in turn drives the circular plate 27 to move the frame plate 25 through the limiting column 28, which in turn drives the connecting plate 24 to move the cleaning roller brush 26. At the same time, the toothed groove 23 drives the long gear 31 to rotate, which simultaneously drives the gear 30 and the cleaning roller brush 26 to rotate, thus cleaning the outer surface of the metal tube 15 and reducing the scale buildup that would affect heat dissipation after long-term use.

[0032] This utility model provides an improved closed-loop cooling tower anti-corrosion heat exchange tube assembly device. During installation, the heat exchange tube assembly 13 is lifted and placed inside the cooling tower 1 using the U-shaped handle 20, allowing the column 16 to slide and be limited by the limiting groove 7. Simultaneously, when the limiting plate 29 is engaged in the slot 17 and the plate 18 is engaged in the slot 11, the U-shaped handle 20 is released, allowing it to move downwards under gravity and block and limit the plate 18, thus achieving quick installation and use. Conversely, quick disassembly can also be achieved. When it is necessary to clean the metal tube 15, the cleaning roller brush 26 is moved and rotated by turning the motor 6, which can clean the outer surface of the metal tube 15, reducing the scale buildup that would affect heat dissipation over long-term use.
