The open cooling device is provided with an air extractor at the top, and the external air is extracted into the open cooling device through the air inlet louver and flows through the filler. The air exchanges heat with the liquid on the surface of the filler, so that the liquid is evaporated and cooled, and then flows into the water tank and then flows into the discharge pipeline, thereby realizing circulation.

The inner cavity of the water tank 2 is fixedly connected with a bottom disc 3, the middle part of the bottom disc 3 is provided with a water outlet hole 31, and the top side edge of the water outlet hole 31 is provided with a cylinder 32.
[0031] The top wall of the bottom disc 3 is fixedly connected with a plurality of wave-shaped partitions 33, the outer end edges of the wave-shaped partitions 33 extend to the side walls of the bottom disc 3, and the inner end edges of the wave-shaped partitions 33 extend to the outer wall of the cylinder 32. The plurality of wave-shaped partitions 33 are uniformly distributed in the circumferential direction, the middle parts of the plurality of wave-shaped partitions 33 protrude in the same direction, and adjacent two wave-shaped partitions 33 and the side walls of the bottom disc 3 and the outer wall of the cylinder 32 surround a water flow cavity 301. The corresponding side walls of the bottom disc 3 at the outer end of the water flow cavity 301 are provided with a plurality of first water inlets 302. The water flow cavity 301 is sequentially provided with a second water partition 34 and a third water partition 35 in the water flow direction, the second water partition 34 and the third water partition 35 both extend in the circumferential direction, and the second water partition 34 and the third water partition 35 separate the water flow cavity 301 into three independent spaces. The second water partition 34 is provided with a plurality of second water inlets 341, and the third water partition 35 is provided with a plurality of third water inlets 351. The corresponding outer wall of the cylinder 32 at the inner end of the water flow cavity 301 is provided with a plurality of fourth water inlets 321.
[0032] The top wall of the cylinder 32 is fixedly connected with a joint piece 36, and the top wall of the joint piece 36 is fixedly connected with a threaded column 361. The top side of each water flow cavity 301 is collectively covered with a cover plate 4, the middle part of the cover plate 4 is provided with a matching hole 41, and the matching hole 41 can match with the joint piece 36. The threaded column 361 is threadedly connected with a lock nut 5.
[0033] Specifically, see Figure 3The number of rows of primary water inlet holes 302, secondary water inlet holes 341, and tertiary water inlet holes 351 decreases progressively.
[0034] Specifically, see Figure 3 One side edge of the secondary baffle plate 34 is connected to the outward protrusion of the corrugated baffle plate 33 of the water flow cavity 301, and the other side edge of the secondary baffle plate 34 is connected to the inward concave part of the other corrugated baffle plate 33 of the water flow cavity 301.
[0035] Specifically, see Figure 3 , Figure 5 The distance between the corresponding side wall of the chassis 3 at the outer end of the water flow cavity 301 and the secondary baffle plate 34 is d1, the distance between the secondary baffle plate 34 and the tertiary baffle plate 35 is d2, and the distance between the tertiary baffle plate 35 and the corresponding outer wall of the cylinder 32 at the inner end of the water flow cavity 301 is d3. d1, d2, and d3 increase in sequence.
[0036] Specifically, in combination Figure 3 , Figure 4 The bottom wall of the cover plate 4 is provided with several wavy mating grooves 42.

[0037] Specifically, see Figure 3 The top edge of the wave-shaped baffle 33 extends beyond the outer end of the water flow cavity 301 to the corresponding side wall of the chassis 3, the secondary baffle 34, and the tertiary baffle 35.
[0038] Specifically, the diameters of the primary water inlet 302, the secondary water inlet 341, the tertiary water inlet 351, and the quaternary water inlet 321 are 14mm-16mm.
[0039] Specifically, the inner cavity of the chassis 3 is provided with eight corrugated baffles 33, which are evenly distributed along the circumference.
[0040] The working principle of this invention is as follows:
[0041] After the circulating cooling water of the air conditioning system participates in the indoor heat exchange, it is heated. The heated cooling water is then sprayed through the liquid delivery pipe 12 onto the packing material (not shown in the figure) inside the open cooling device 1. An exhaust fan is installed at the top of the open cooling device 1. Outside air is drawn into the open cooling device 1 through the air inlet louvers 11 and flows through the packing material. The air exchanges heat with the liquid on the surface of the packing material, causing the liquid to partially evaporate and cool down. The cooled liquid flows into the water tank 2 and then into the discharge pipe 21, thus realizing the circulation of the cooling water in the air conditioning system.
[0042] The bottom plate 3 is fixed to the bottom wall of the inner cavity of the water tank 2, and the water outlet hole 31 of the bottom plate 3 is connected with the water inlet of the discharge pipeline 21. When the water of the open cooling device 1 enters the water tank 2, the water in the water tank 2 enters the space between the side wall of the bottom plate 3 and the second water baffle 34 through the first water inlet hole 302, then the water enters the space between the second water baffle 34 and the third water baffle 35 through the second water inlet hole 341 arranged on the second water baffle 34, then the water enters the space between the third water baffle 35 and the cylinder 32 through the third water inlet hole 351 arranged on the third water baffle 35, then the water enters the cylinder 32 through the fourth water inlet hole 321 arranged on the cylinder 32, and then flows into the discharge pipeline 21.
[0043] Since the number of the first water inlet hole 302, the number of the second water inlet hole 341 and the number of the third water inlet hole 351 decrease gradually, and d1, d2 and d3 increase gradually, the flow rate of the water flow through the first water inlet hole 302, the second water inlet hole 341, the third water inlet hole 351 and the fourth water inlet hole 321 decreases gradually. Moreover, the water flow is limited by the outline of the three sub-cavities of the water flow cavity 301, and cannot cross the wave-shaped baffle 33, so that the water flow cannot realize large circumferential flow, and thus a vortex cannot be formed at the water outlet of the bottom wall of the water tank 2.
[0044] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as the above preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content to obtain equivalent embodiments with equivalent changes, as long as the changes or modifications do not deviate from the technical solution of the present application. Any modification, change and modification of the above embodiment according to the technical essence of the present application are still within the scope of the technical solution of the present application.
