DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0018] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper surface", "lower surface", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "forward", "reverse", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a water distributor 14 with a diffusion strip groove comprises a diffusion strip groove 1, a diverter groove 2 and a guide plate 3. The diffusion strip groove 1 is a gradual deformation structure with a large upper port and a small lower port. The upper port of the diverter groove 2 is connected to the lower port of the diffusion strip groove 1. The guide plate 3 is arranged at the lower port of the diverter groove 2 and closes the lower port of the diverter groove 2. A limit mounting plate 4 is arranged at the connection between the diffusion strip groove 1 and the diverter groove 2. The limit mounting plate 4 is used to be installed at the drain outlet on the bottom surface of the water distribution basin. The diverter groove 2 is provided with peripheral water spray holes 5 on the front and rear faces and the left and right sides. The guide plate 3 is provided with downward water spray holes 6 directly below the diverter groove.

[0020] After the diffusion strip groove 1 and the diversion groove 2 are installed on the water distribution basin by means of the limiting mounting plate 4, the diffusion strip groove 1 is located in the space above the bottom surface of the water distribution basin, so that the upper diffusion surface of the diffusion strip groove 1 has a certain height, ensuring that when the cooling water in the water distribution basin enters the diffusion strip groove 1, the sediment deposited on the bottom surface of the water distribution basin will not directly enter the water distributor 14, ensuring that the water sprinkling filler channel will not be blocked, thereby effectively ensuring the heat exchange effect.

[0021] The limiting mounting plate 4 is connected and fixed to the water distribution basin to ensure that the water distributor 14 does not move up and down, and ensures that the water distributor 14 can spray normally.

[0022] The left and right sides of the diffusion strip groove 1 are arc surfaces; the left and right sides of the diverter groove 2 are arc surfaces. The diverter groove 2 has diverter peripheral water spray holes 5 on the left and right arc surfaces to ensure that the cooling water is evenly distributed at the four corners of the water distributor 14 without spraying dead corners, so that the spray filler can fully ensure heat exchange and improve thermal performance.

[0023] A partitioning vertical plate 7 is provided inside the diffusion strip groove 1, and the partitioning vertical plate 7 divides the diffusion strip groove into two left and right cavities. The partitioning vertical plate 7 extends downward into the diversion groove 2 and a gap is reserved between the plate surface of the guide plate 3. The interior of the diffusion strip groove 1 has a narrow and long elliptical diversion groove, which is an effective flow path for cooling water. The partitioning vertical plate 7 divides the cooling water into two left and right parts, forming two branches.

[0024] The guide plate 3 is provided with a guide groove 8 at the front and rear sides of the diverter groove 2, and a guide hole 9 is provided at the front and rear sides of the diverter groove 2 and near the guide groove 8. The water in the diverter groove 2 is sprayed to the guide groove 8 through the guide hole 9, and the water is sprayed outward in a parabolic shape along the guide groove 8. The guide groove 8 is a circular arc groove structure. In this way, the cooling water is more effectively sprayed evenly on each piece of the spray filler, so that the entire heat exchange filler can evenly and effectively ensure heat exchange, thereby improving the overall thermal performance.

[0025] A diversion protrusion 10 is provided on the upper surface of the guide plate 3, and the diversion protrusion 10 is located in the diversion groove 2, and the downward water spray holes 6 are distributed on the diversion protrusion 10. Two angled inclined surfaces are designed on both sides of the diversion protrusion 10, so that the cooling water can flow in different directions and be evenly arranged to form a thin film so that the cooling water can participate in heat exchange more effectively.

[0026] like Figure 8 As shown, a cooling tower includes a tower body 11, a filler 12 and a water distribution tray 13. The water distribution tray 13 and the filler 12 are arranged in the tower body 11, and the filler 12 is located below the water distribution tray 13. A water distributor 14 with a diffusion strip groove is provided at the bottom of the water distribution tray 13. A plurality of drain ports 15 are distributed on the bottom surface of the water distribution tray 13, and a water distributor 14 with a diffusion strip groove is provided at each drain port 15. The height of the diffusion strip groove 1 in the water distributor with the diffusion strip groove is not greater than 1 / 10 of the depth in the water distribution tray 13, and not less than 1 / 20 of the depth in the water distribution tray 13.

[0027] In addition, those skilled in the art may combine and combine the different embodiments or examples and the features of the different embodiments or examples described in this specification without contradiction. Although the embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and cannot be understood as limiting the present invention.
