Description

Technical Field

[0001] This utility model relates to the field of splash heat dissipation components, specifically a splash heat dissipation component for cooling towers with a flow guiding structure. Background Technology

[0002] In air conditioning systems of industrial production and large buildings, cooling towers, as key heat exchange equipment, play an important role in exchanging heat between cooling water carrying waste heat and air, thereby reducing the temperature of the cooling water for recycling.

[0003] Currently, there are related improvements to the mainstream single spray head designs on the market. According to the patent "Water Spray Head for Cooling Towers" with authorization announcement number CN201858927U, this patent improves the problems of large water droplets and small spray area of ​​traditional three-spray nozzles by using a longitudinally adjustable nozzle body and a cross-shaped twisted blade spray core. However, as an inherent structure of a single spray head, it requires a large number of nozzles to be densely installed to cover the entire packing layer in actual use. This not only increases the equipment purchase cost, but also makes it very easy for the spraying area to overlap or be missed due to installation errors. This results in some areas being overloaded and some areas being short of water. This leads to uneven distribution of cooling water on the packing layer, with some areas having concentrated cooling water and others having insufficient cooling water. The uneven distribution of cooling water prevents sufficient heat exchange between air and cooling water, greatly reducing the overall heat dissipation efficiency of the cooling tower and failing to meet the high-efficiency heat dissipation requirements of industrial production and large building air conditioning systems.

[0004] Therefore, this utility model provides a splash heat dissipation component for cooling towers with a flow guiding structure to solve the above problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] This utility model provides a splash heat dissipation component for cooling towers with a flow guiding structure, such as... Figures 1-4As shown, the system includes a connecting pipe 1, a guide pipe 5 at the lower end of the connecting pipe 1, and multiple sets of first connecting rods 2 fixedly installed circumferentially on the outer surface of the bottom end of the connecting pipe 1. A first water-spraying disc 3 is fixedly connected between the multiple sets of first connecting rods 2 and the guide pipe 5. Multiple sets of second connecting rods 21 are fixedly connected to the bottom ends of the multiple sets of first connecting rods 2. A second water-spraying disc 4 is provided below the first water-spraying disc 3, and the lower end of the second water-spraying disc 4 is fixed to the lower end of the multiple sets of second connecting rods 21. A drainage cone 7 is provided in the center of both the first water-spraying disc 3 and the center of the second water-spraying disc 4. A guide pipe 5 is provided in the center of the drainage cone 7 located in the first water-spraying disc 3. The top end of the guide pipe 5 is located on the inner wall of the connecting pipe 1, and the bottom end of the guide pipe 5 extends to the first water-spraying disc 3. Below, the guide cone 7 in the second water spray dish 4 is located at the lower end of the outlet of the guide pipe 5. The connecting pipe 1 supports the first water spray dish 3 and the second water spray dish 4 through the first connecting rod 2 and the second connecting rod 21 respectively, so that the water can be sprayed at different heights, increasing the contact time and area between the water and the air, and effectively improving the heat dissipation efficiency. Since the guide cone 7 is provided in the center of both the first water spray dish 3 and the second water spray dish 4, the setting of the guide cone 7 can change the flow direction of the water. The water flowing into the connecting pipe 1 is diverted and can be more evenly dispersed to the surroundings under the high-speed rotation of the impacting first water spray dish 3 and the second water spray dish 4. A filter assembly is provided on the inner wall of the connecting pipe 1 for filtering the water.

[0021] Among them, radially distributed protrusions are provided on the conical surface of the diversion cone 7. When the water flow impacts the surface of the diversion cone from the guide pipe or connecting pipe, the radially distributed protrusions can directly divide the concentrated water flow into multiple independent small water flows, avoiding the water flow from converging towards the center due to surface tension.

[0022] Among them, the cone surface of the diversion cone 7 is provided with a radially concave diversion groove, which can stably guide the water flow impacting the cone surface along the groove to the edge of the water spray dish, and avoid water flow deviation caused by water pressure fluctuation.

[0023] The filter assembly includes a limiting ring 9 fixedly installed in the inner wall of the connecting pipe 1, and a filter pipe 8 is placed on the limiting ring 9. The bottom wall of the filter pipe 8 is a stainless steel filter mesh structure. The stainless steel filter mesh structure has the characteristics of corrosion resistance and high strength, and can filter water stably for a long time, ensuring that the water entering the subsequent water spraying structure is clean and avoiding impurities from clogging the dispersion structure on the first water spraying disc 3 and the second water spraying disc 4 as well as the guide pipe 5.

[0024] The filter tube 8 has symmetrically arranged strip grooves 81 on its inner wall. When a lot of impurities accumulate in the filter tube 8 and it needs to be cleaned or replaced, the operator can easily remove the filter tube 8 from the limiting ring 9 through the strip grooves 81 to clean or replace the filter tube 8, which improves the convenience and efficiency of maintenance.

[0025] As a preferred technical solution of this utility model, the outer surface of the top end of the connecting pipe 1 is provided with a threaded groove 11. The connection is tight and reliable through the threaded connection, which can effectively prevent water leakage and ensure that water can stably enter the connecting pipe 1 and then enter the entire spray heat dissipation assembly for heat dissipation treatment, thereby improving the stability and reliability of the system.

[0026] Multiple sets of dispersion plates 6 are fixedly installed on the outer surfaces of the first water-spraying disc 3 and the second water-spraying disc 4. The dispersion plates 6 distributed on the outer surfaces of the first water-spraying disc 3 and the second water-spraying disc 4 are on the same conical surface. When water hits the first water-spraying disc 3 and the second water-spraying disc 4, the dispersion plates 6 can divide the water into smaller water droplets or more dispersed water streams, which greatly increases the contact area between the water and the air, improves the heat exchange efficiency, and enables the cooling tower to reduce the temperature of the cooling water to the required level in a shorter time, thereby improving the performance of the entire cooling system.

[0027] The top of the guide pipe 5 is fixedly installed with multiple sets of fixing rods 51, which are fixedly connected to the inner wall of the connecting pipe 1 to ensure that the guide pipe 5 will not shake or shift during the flow of water.

[0028] Working principle: First, the connecting pipe 1 is securely connected to the external water supply pipe through the threaded groove 11 on the outer surface of the top end of the connecting pipe 1, ensuring that water can smoothly enter the component.

[0029] When the external water supply pipe starts supplying water, the water flows in from the upper end of the connecting pipe 1. During the flow, the water first passes through the filter pipe 8 placed on the limiting ring 9. The bottom wall of the filter pipe 8 is a stainless steel filter screen structure, which can effectively intercept impurities and particles in the water and prevent them from entering the subsequent structure and causing blockage or affecting the heat dissipation effect. If it is necessary to clean or replace the filter pipe 8, the operator can easily and quickly remove the filter pipe 8 from the limiting ring 9 through the symmetrically opened strip grooves 81 on the inner wall of the filter pipe 8.

[0030] After filtration, the water continues to flow downwards and is discharged from the bottom of the connecting pipe 1. The discharged water first hits the first water spray plate 3. Multiple sets of dispersion plates 6 are fixedly installed on the outer surface of the first water spray plate 3. These dispersion plates 6 can further disperse the water hitting the first water spray plate 3, so that the water is dispersed in a finer droplet or more dispersed state, increasing the contact area between the water and the air. Meanwhile, the guide pipe 5 inside the connecting pipe 1 plays a key guiding role. The top of the guide pipe 5 is fixedly connected to the inner wall of the connecting pipe 1 by multiple sets of fixing rods 51 to ensure its stable position. The top of the guide pipe 5 is located on the inner wall of the connecting pipe 1, and the bottom extends to the bottom of the first water spray plate 3. Some water is guided downward through the guide pipe 5 and directly impacts the second water spray plate 4. Multiple sets of dispersing plates 6 are also fixedly installed on the outer surface of the second water spray plate 4. After the water impacts the second water spray plate 4, it is dispersed again, further expanding the spray range of the water and enabling the water to be more evenly distributed on the packing layer of the cooling tower.

[0031] The multiple sets of dispersing plates 6 on the first water-spraying disc 3 and the second water-spraying disc 4 are staggered circumferentially. This allows the water flowing in from the connecting pipe 1 to be cooled to be subjected to a double-layered impact from the multiple sets of dispersing plates 6 fixed to the outer surfaces of the first and second water-spraying discs 3 and 4. This disperses the water into finer droplets, resulting in a more dense and uniform dispersion, a larger dispersion space, and increased contact area between the water and air; thus, a better cooling effect. According to the applicant's tests, this invention can reduce the cooling water temperature by 0.15 degrees Celsius, demonstrating a significant energy-saving effect.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
