[0037] The technical solutions of the present application will be described below in conjunction with the drawings, obviously, the following described embodiments are part of the embodiments of the present application, not all the embodiments.

[0038] The existing cross-flow cooling tower has the phenomenon of uneven water flow distribution in actual operation, which affects the cooling effect, and water is easily carried out by air flow and water is easily flowed out from the air inlet 150 on both sides, which consumes a large amount of water, and further the present application proposes a high-efficiency cross-flow cooling tower.

[0039] The high-efficiency cross-flow cooling tower of the present application comprises: a tower body 100, a fan assembly 200, a spray assembly and a filler assembly.

[0040] As Figure 1As shown, the tower body 100 is internally provided with two water spraying cooling cavities 110, an air outlet cavity 120 and a water collecting groove 130. The two water spraying cooling cavities 110 are respectively located at the left and right sides of the air outlet cavity 120. In other embodiments, the two water spraying cooling cavities 110 can be respectively located at the front and rear sides of the air outlet cavity 120. The present embodiment takes the example that the water spraying cooling cavities 110 and the air outlet cavity 120 are arranged along the left-right direction.

[0041] The lower parts of the two water spraying cooling cavities 110 and the air outlet cavity 120 are in communication with each other, and the water collecting groove 130 is located below the two water spraying cooling cavities 110 and the air outlet cavity 120. It can be understood that the tower body 100 is provided with two partitions 140, which are arranged along the left-right direction at intervals. The two partitions 140 form the air outlet cavity 120 therebetween, and the two partitions 140 and the left and right inner side walls of the tower body 100 respectively form the water spraying cooling cavities 110 therebetween. The lower edges of the two partitions 140 and the bottom of the tower body 100 form a gap to form the water collecting groove 130. Meanwhile, the water surface of the water collecting groove 130 and the lower edges of the partitions 140 form a flow gap to enable the two water spraying cooling cavities 110 and the air outlet cavity 120 to communicate with each other.

[0042] The two water spraying cooling cavities 110 are respectively provided with air inlets 150 located at the side surfaces of the tower body 100. In the present embodiment, the air inlets 150 are formed on the left and right side walls of the tower body 100. The air outlet cavity 120 is provided with an air outlet 160 located at the top of the tower body 100. The air inlets 150, the water spraying cooling cavities 110, the air outlet cavity 120 and the air outlet 160 form a cooling air duct.

[0043] The fan assembly 200 of the present embodiment is installed at the air outlet 160. The fan assembly 200 serves as an air inducer to form a negative pressure in the air outlet cavity 120, so that air flows along the air inlets 150, the water spraying cooling cavities 110, the air outlet cavity 120 and the air outlet 160 in sequence.

[0044] The packing assembly of the present embodiment includes a packing device 300 arranged in the water spraying cooling cavities 110.

[0045] The spray assembly includes a plurality of spray pipes 400 distributed at the top of the two water spraying cooling cavities 110. The spray pipes 400 are distributed along the horizontal direction. The bottoms of the spray pipes 400 are uniformly provided with a plurality of spray heads 410. Figure 2 As shown, the spray head 410 includes a downwardly directed spray nozzle 411 and a water distribution disc 412 arranged below the spray nozzle 411. The spray nozzle 411 is in communication with the interior of the spray pipe 400. The water distribution disc 412 is fixedly arranged below the spray nozzle 411. A gap is left between the lower end of the spray nozzle 411 and the water distribution disc 412.

[0046] In use, water is transported along multiple spray pipes 400. When passing through the spray head 410, the water is sprayed down from the spray nozzle 411 to the water distribution plate 412. The water distribution plate 412 blocks the water to disperse it.

[0047] In some embodiments, multiple spray pipes 400 are connected to a spray pump, which pressurizes the water to improve the spraying effect.

[0048] like Figure 1 As shown, in this embodiment, a first baffle plate 111 is provided on the inner side wall of the upper part of the water cooling chamber 110. The first baffle plate 111 is inclined from top to bottom towards the inner side of the water cooling chamber 110 to block the water, so that the water does not flow down along the inner side wall of the water cooling chamber 110, thereby preventing the water from flowing out from the side air inlet 150, and also causing the water to concentrate in the middle position of the water cooling chamber 110 and spray down into the packing device 300.

[0049] like Figure 5 As shown, under the operation of the fan assembly 200, a negative pressure is formed in the air outlet chamber 120. External air enters the water spray cooling chamber 110 from the air inlets 150 on both sides. The sprayed water comes into contact with the water in the packing device 300 and exchanges heat, carrying away the heat in the water to achieve cooling. The cooled water is collected through the water collection tank 130. The hot air flows from top to bottom in the water spray cooling chamber 110, then bypasses the liquid surface of the water collection tank 130 and enters the air outlet chamber 120. The hot air flows from bottom to top in the air outlet chamber 120 and is blown out from the air outlet 160 at the top. When the hot air enters the air outlet chamber 120 from the water spray cooling chamber 110, it turns to form a centrifugal force, throwing the water it carries into the water collection tank 130, thereby reducing the amount of water carried out by the airflow. This utility model can improve the spraying effect, improve the uniformity of water flow distribution, improve the cooling performance of the device, and reduce water consumption.

[0050] Regarding the specific structure of the spray head 410, such as Figure 2 As shown, in this embodiment, at least two connecting rods 413 are inclinedly arranged between the water dispersion tray 412 and the spray nozzle 411. The water dispersion tray 412 and the spray nozzle 411 are arranged coaxially. The outer diameter of the water dispersion tray 412 is larger than that of the spray nozzle 411. The upper end of the connecting rod 413 is connected to the outer peripheral wall of the spray nozzle 411, and the lower end of the connecting rod 413 is connected to the outer edge of the water dispersion tray 412, so as to fix the water dispersion tray 412 and reduce water obstruction.

[0051] Furthermore, such as Figure 4As shown, the water dispersion tray 412 of the embodiment comprises a plurality of fan-shaped plates 4121 arranged in a ring shape, which disperse water, and water can flow through the gaps between adjacent fan-shaped plates 4121 to improve the water spraying effect.

[0052] As shown, the water dispersion tray 412 of the embodiment comprises a plurality of fan-shaped plates 4121 arranged in a ring shape, which disperse water, and water can flow through the gaps between adjacent fan-shaped plates 4121 to improve the water spraying effect. Figure 2 As shown, the water dispersion tray 412 of the embodiment comprises a plurality of fan-shaped plates 4121 arranged in a ring shape, which disperse water, and water can flow through the gaps between adjacent fan-shaped plates 4121 to improve the water spraying effect.

[0053] As shown, the water dispersion tray 412 of the embodiment comprises a plurality of fan-shaped plates 4121 arranged in a ring shape, which disperse water, and water can flow through the gaps between adjacent fan-shaped plates 4121 to improve the water spraying effect. Figure 1 and Figure 3 As shown, the air inlet 150 of the embodiment is provided with a plurality of air deflectors 151 arranged in a row from top to bottom, which are inclined outward from top to bottom, wherein the upper ends of the air deflectors 151 extend into the water cooling chamber 110, and the lower ends of the air deflectors 151 extend outside the tower body 100.

[0054] The air deflectors 151 of the embodiment can prevent dust from entering the air inlet 150 and guide the air entering the air inlet 150, as shown. Figure 5 As shown, when the air enters the air inlet 150, it is guided by the air deflectors 151 and inclined upward into the water cooling chamber 110 to improve the turbulence of the air in the water cooling chamber 110 and improve the cooling performance. After the air enters the upper part of the water cooling chamber 110, it flows downward, then turns around the liquid surface of the water collecting tank 130, and then enters the air outlet chamber 120. The air in the water cooling chamber 110 and the air outlet chamber 120 performs a tail swing to form a centrifugal effect, so that the water is thrown out into the water collecting tank 130.

[0055] In some embodiments, the air deflectors 151 can be rotatably arranged to swing up and down to adjust the upper and lower ends of the air deflectors 151. In actual operation, the air deflectors 151 can be reciprocally rotated to blow the filler device 300 to improve the cooling effect and dry the filler device 300.

[0056] In some embodiments, a rotary driving mechanism can be provided to drive the air deflectors 151 to rotate.

[0057] To further reduce water consumption, this embodiment provides a second baffle plate 121 on the inner wall of the air outlet cavity 120. The second baffle plate 121 is inclined from top to bottom and outward to form a horn structure in the air outlet cavity 120 with an inner diameter that gradually decreases from bottom to top, so as to throttle the airflow and intercept water in the air on the second baffle plate 121, which finally flows back to the water collection tank 130.

[0058] The packing device 300 of this embodiment includes multiple packing bodies 310 arranged vertically. The multiple packing bodies 310 are arranged at intervals in the front-to-back direction, and an air heat exchange gap is formed between the multiple packing bodies 310. Air enters the air heat exchange gap and comes into contact with water for heat exchange.

[0059] In this embodiment, the packing body 310 is provided with several insertion interfaces, and several fixing rods 320 are inserted between multiple packing bodies 310. The fixing rods 320 are inserted into the insertion interfaces to achieve fixed installation of the packing body 310.

[0060] In this embodiment, the bottom of the water collection tank 130 is recessed with a water collection trough 131, and the side of the water collection trough 131 is provided with a water outlet 132. In this way, when the water in the water collection tank 130 is used, it can be pumped out by an external water pump. The setting of the water collection trough 131 can avoid the phenomenon of water pump losing vacuum due to low water level.

[0061] The bottom of the tower body 100 is provided with multiple support legs 170, which support the entire device.
