Description

Technical Field

[0001] This utility model relates to the field of industrial cooling technology, specifically a novel water-saving closed-loop cooling tower. Background Technology

[0002] Cooling towers are crucial for ensuring normal equipment operation and maintaining suitable ambient temperatures in numerous fields, including industrial production, data centers, and large commercial buildings. However, traditional open cooling towers suffer from significant water waste during operation. Open cooling towers exchange heat through direct contact between water and air, causing the cooling water to continuously evaporate within the tower. To maintain the normal operation of the cooling system, a large amount of fresh water needs to be constantly replenished. Closed-circuit cooling towers, on the other hand, offer significant advantages in water conservation compared to open cooling towers. They employ indirect heat exchange, with cooling water circulating within a closed piping system, avoiding direct contact with outside air, thus greatly reducing water evaporation loss. Theoretically, the water evaporation loss of closed-circuit cooling towers is only a fraction of that of open cooling towers, or even less, making them a highly promising solution for water conservation.

[0003] Existing closed-circuit cooling towers first continuously flow hot water that needs to be cooled through multiple layers of curved pipes, and then spray cold water onto the pipes to achieve a cooling effect. As the hot water flows through the pipes, the central water flow is fast, while the water flow near the pipe wall is slow due to friction with the pipe wall, resulting in insufficient heat exchange efficiency.

[0004] Therefore, there is an urgent need for a water-saving closed cooling tower that breaks the boundary layer and enhances heat exchange through a threaded water pipe structure. Utility Model Content

[0005] To address the aforementioned issues, this invention provides a novel water-saving closed-loop cooling tower. Its threaded water pipe increases the contact area and time between water and air, and also generates a rotating vortex within the pipe, breaking the boundary layer and improving cooling efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A novel water-saving closed-loop cooling tower, comprising a tower body:

[0007] The tower body has multiple first water inlet pipes symmetrically arranged on both sides, extending from the outside to the inside. Spray pipes are connected between each of the first water inlet pipes on both sides. The spray pipes are located at the top of the tower body. A fan is provided at the top of the tower body.

[0008] The tower body is equipped with an installation frame, and the installation frame is equipped with multiple U-shaped connecting pipes. Each U-shaped connecting pipe is rotatably connected to a water supply pipe, and all water supply pipes are connected through the U-shaped connecting pipes. The water supply pipes are arranged in multiple layers, and each layer of water supply pipes is connected through the U-shaped connecting pipes.

[0009] The water supply pipe has a threaded structure.

[0010] In some embodiments, one end of each water pipe is provided with a gear, the mounting bracket is provided with a cylinder, the output end of the cylinder is provided with a rack, and the rack meshes with the gear.

[0011] In some embodiments, the bottom of the tower body has a V-shaped structure.

[0012] In some embodiments, a filter screen is provided on the top of the tower body below the fan.

[0013] In some embodiments, the water pipes in each layer are staggered.

[0014] In some embodiments, the inner wall of each water pipe is coated with a scale-resistant coating.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model's mesh cage utilizes a multi-layered, threaded water supply pipe connected by U-shaped connecting pipes on a mounting frame. The threaded structure not only increases the contact area and time between water and air but also generates a rotating vortex within the pipe, breaking the boundary layer and improving cooling efficiency. The staggered arrangement of the water supply pipes facilitates uniform airflow and even spraying of cold water, further optimizing heat exchange. A cylinder-driven rack and pinion mechanism rotates the water supply pipes, allowing for flexible adjustment of the pipe angle according to actual working conditions and ensuring even spraying of cold water to every direction and angle, adapting to different cooling needs and improving equipment adaptability and operational efficiency. The V-shaped structure at the bottom of the tower facilitates water collection and drainage, reducing water residue. A filter screen below the top fan traps some water droplets in the generated steam. A waterproof coating on the inner wall of the water supply pipes prevents scale buildup, ensuring unobstructed flow and reducing maintenance costs and water consumption caused by scale, thus achieving both water conservation and high-efficiency operation.

[0029] Please see Figure 1-7 This embodiment provides a novel water-saving closed-loop cooling tower, including a tower body 1. The tower body is square, with a hollow interior, similar to a square cover.

[0030] Multiple first water inlet pipes 2 are symmetrically arranged on both sides of the tower body 1, running from the outside to the inside. Spray pipes 3 are connected between each of the first water inlet pipes 2 on both sides, and are welded together. The spray pipes 3 are made of smooth-walled PVC to reduce water flow resistance. The spray pipes 3 are located at the top of the tower body 1 and have multiple evenly distributed small spray holes that spray cooling water in the form of a fine mist. A fan 5 is installed at the top of the tower body 1. The blades of the fan 5 are made of lightweight aluminum alloy, which generates wind during operation, accelerating airflow inside the tower and ensuring that the sprayed cooling water comes into full contact with the air, carrying away heat.

[0031] The tower body 1 contains a mounting frame 61 with multiple U-shaped connecting pipes 6. Each U-shaped connecting pipe 6 is rotatably connected to a water supply pipe 7. Each U-shaped connecting pipe 6 is rotatably connected to a water supply pipe 7 via a specially designed high-temperature resistant bearing. The water supply pipe 7 is a copper tube with heat dissipation fins on its outer wall. The heat dissipation fins increase the contact area between the water supply pipe 7 and the surrounding air, enabling more efficient dissipation of heat from the cooling medium inside the pipe. All water supply pipes 7 are connected by U-shaped connecting pipes 6, which are made of stainless steel to reduce friction at the connection points with the water supply pipes 7, ensuring smooth rotation of the water supply pipes 7. There are three layers of water supply pipes 7, each connected by U-shaped connecting pipes 6, forming a three-dimensional cooling network. The cooling medium circulates within the water supply pipes 7, fully exchanging heat with the air inside the tower.

[0032] like Figure 4 As shown, the water pipe 7 has a threaded structure. The threaded structure can increase the area of ​​the water pipe 7 that is sprayed with cold water, and can also generate a rotating vortex and break the boundary layer when the hot water that needs to be cooled flows in the water pipe 7.

[0033] The boundary layer is where the water flow is fastest and smoothest, while the water near the pipe wall is almost still due to friction. Breaking the boundary layer is achieved by using a spiral structure to generate a rotating vortex. The water flow is forced to rotate along the spiral pipe, generating centrifugal force. Like a washing machine spinning clothes, the water in the center is thrown towards the pipe wall, while the water on the pipe wall is pushed back to the center, thus achieving a highly efficient and rapid cooling effect.

[0034] In some embodiments, such as Figure 4As shown, each water pipe 7 has a gear 10 at one end, and the gears 10 on each water pipe 7 mesh with each other. A cylinder 11 is provided on the mounting bracket 61, and a rack 12 is provided on the output end of the cylinder 11. The rack 12 meshes with the gear 10. When the cylinder 11 moves up and down, it drives the rack 12 to move up and down as well. The gear 10 meshing with the rack 12 rotates, thereby driving the other gears 10 and the water pipe 7 to rotate. When the water pipe 7 rotates, the cooling water inside the pipe is evenly distributed on the outer wall of the pipe under the action of centrifugal force and gravity to form a stable water film. Compared with a fixed water pipe, this dynamic water film increases the contact area between water and air, enhances heat exchange, improves cooling efficiency, and can dissipate heat faster to meet the cooling speed requirements of different working conditions. At the same time, the rotation of the water pipe 7 generates local air disturbance, breaks the stable air flow, promotes the mixing of air and water film, and allows the air to contact the water film more fully and carry away more heat. Especially in high temperature and high humidity environments, it can prevent the formation of a thermal boundary layer on the surface of the water film and ensure continuous and efficient cooling.

[0035] In some embodiments, the bottom of the tower body 1 has a V-shaped structure, which allows for the effective collection of water sprayed from the spray pipe 3.

[0036] In some embodiments, such as Figure 7 As shown, a filter screen 13 is installed at the top of the tower body 1, below the fan 5, and a large number of fluffy tufts are attached to the filter screen 13. When the steam generated inside the tower is drawn out to the outside by the fan, the steam will pass through the filter screen 13, at which time the fluffy tufts can absorb some water droplets.

[0037] In some embodiments, such as Figure 6 As shown, the water supply pipes 7 of each layer are staggered. The staggered position allows the cold water sprayed into the water supply pipes 7 to be sprayed evenly to each layer, avoiding the problem of uneven spraying and failure to spray the lower layers.

[0038] In some embodiments, the inner wall of each water pipe 7 is coated with a scale-resistant coating. Since scale will be generated inside the water pipe 7 after long-term use, the scale-resistant coating can prevent the formation of scale.

[0039] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
