Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a cooling tower group control water distribution device for air conditioners. Background Art

[0002] At present, domestic mechanical ventilation cooling towers mainly adopt conventional structural design, and the water distribution of general cooling towers is completed by the sprinkler tray. Conventional cooling tower design is only for the design flow condition. The water volume of the sprinkler tray is relatively large, and water can flow through the water distribution holes of the water tray, which can basically achieve balanced water distribution. However, in recent years, the group control technology of air-conditioning cooling towers has developed rapidly, especially the group control technology of central air-conditioning cooling towers. Basically, all cooling towers are frequency-controlled and work at partial load (cooling water flow is lower than the rated flow) for a long time. The cooling tower flow is far lower than the rated flow (30%-100%). As a result, when the water volume is low, some areas of the sprinkler tray have no water, the water volume is unevenly distributed, and the cooling tower's heat dissipation effect is greatly reduced.

[0003] In response to this situation, some domestic manufacturers have introduced flow nozzles, that is, installing flow nozzles on the water distribution holes of the sprinkler disc to make the water rotate and improve the balance of water distribution. However, this method is costly and troublesome to install. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1:

[0024] See also Figure 1-4 The utility model provides a technical solution: a watering plate 1, a cover plate 2 is provided on the top of the watering plate 1, a water supply pipe 3 is fixedly connected to the surface of the cover plate 2, a water flow hole 4 is opened at the bottom of the watering plate 1, a water distribution cavity 8 is opened in the watering plate 1, and a balanced water distribution component 5 is provided in the water distribution cavity 8;

[0025] The balanced water distribution assembly 5 includes a water distribution cylinder 501 disposed within the water distribution chamber 8. The surface of the water distribution cylinder 501 is sequentially provided with a first water permeable hole 502, a second water permeable hole 503, a third water permeable hole 504, and a fourth water permeable hole 505 from top to bottom. A water permeable cavity 506 is also provided on the surface of the water distribution cylinder 501. The water permeable cavity 506 is fixedly connected to the water flow hole 4. The first water permeable hole 502, the second water permeable hole 503, the third water permeable hole 504, and the fourth water permeable hole 505 are all fixedly connected to the water permeable cavity 506. In the prior art, the water distribution plate 6 is provided with water distribution holes 7. When the water flow rate is low, the water flow is unevenly distributed, reducing the heat dissipation effect.

[0026] Analysis of the above content: The utility model provides water-permeable holes of different apertures on the surface of the water distribution cylinder 501. When the water inlet of the cooling tower is different, the water flow entering the sprinkler plate 1 is controlled to ensure that water flows through all the holes of the sprinkler plate 1, thereby achieving the effect of balanced water distribution. It can be used by adding a balanced water distribution component 5 to the traditional cooling tower sprinkler plate without the need to modify the original cooling tower. The balanced water distribution component 5 has a simple structure, is relatively easy to manufacture, and has low cost, making it easy to promote and use. Water flows into the water distribution chamber 8 through the water supply pipe 3, and under the action of the balanced water distribution component 5, the water flows out evenly from the water flow hole 4, ensuring the uniformity of the water flow, ensuring the uniformity of the water distribution, and improving the heat dissipation effect of the cooling tower.

[0029] Analysis of the above content: The conical structure provides a large contact area with water, improving flow efficiency. The conical structure features holes of varying sizes from bottom to top. When the water flow is low, water flows through the small holes, while when the water flow is high, water flows through the large holes. The system can adaptively adjust to different flow rates, ensuring that water flows evenly through the four drainage holes.

[0032] Analysis of the above content: when the water inlet is small, water flows out from the small holes; when the water inlet is large, water flows out from the large holes. At different flow rates, the system can adaptively adjust to ensure that water flows out evenly from the water holes 4, avoiding the situation where a group of water holes 4 do not flow water, thereby improving the heat dissipation effect of the cooling tower.

[0035] Analysis of the above content: When the water flow rate is large, it flows into the water flow hole 4 from the top of the water distribution cylinder 501, which has an anti-overflow effect.

[0036] Embodiment 5:

[0037] See also Figure 1-4 The present invention provides a technical solution based on the first embodiment: the water supply pipe 3 is fixedly connected to the external water source, and the water supply pipe 3 is set as a plastic pipe.

[0038] Analysis of the above content: External water flows into the water distribution cavity 8 through the water supply pipe 3, and is evenly discharged from the water flow hole 4 under the action of the balanced water distribution component 5, thereby improving the uniformity of water distribution, improving the heat dissipation effect of the cooling tower, and improving the heat dissipation effect and heat dissipation speed.

[0039] Example 6:

[0040] See also Figure 1-4 The present invention provides a technical solution based on the first embodiment: the diameter of the water flow hole 4 is the same as the bottom diameter of the water permeable cavity 506, and the water permeable cavity 506 is set in a conical shape.

[0041] Analysis of the above content: when the water inflow is small, water flows out of the small holes, and when the water inflow is large, water flows out of the large holes. The system can adjust adaptively at different flow rates. Water flows into the water-permeable cavity 506 through different holes and is discharged from the water flow hole 4.
