[0031] The utility model provides an air cooler.

[0032] See also Figure 1 In one embodiment of the utility model, the air cooler includes a shell 1, the side wall of the shell 1 has an air inlet 11 and an air outlet 12; at least three water curtain assemblies 2, arranged in the shell 1, the at least three water curtain assemblies 2 are surrounded by an installation space 21, and one side of the installation space 21 has an opening 211; a water supply assembly 3, arranged in the shell 1, the water supply assembly 3 is used to supply water to the at least three water curtain assemblies 2; and a fan assembly 4, arranged in the installation space 21, the air inlet side of the fan assembly 4 is facing at least one of the water curtain assemblies 2, and the air outlet side of the fan assembly 4 is facing the opening 211; the fan assembly 4 is used to drive the outside air into the shell 1 from the air inlet 11 and pass through the at least three water curtain assemblies 2 and then be sent out from the air outlet 12.

[0033] The technical solution of the present invention is to form an installation space 21 by adopting at least three water curtain assemblies 2, and the fan assembly 4 is arranged in the installation space 21. By setting the air inlet side of the fan assembly 4 to face any one of the at least three water curtain assemblies 2, when the fan assembly 4 drives the outside air to enter the shell 1 from the air inlet 11, the outside air passes through at least three water curtain assemblies 2 respectively, so that the water in the at least three water curtain assemblies 2 and the heat of the outside air evaporate and absorb heat, thereby increasing the heat exchange area between the outside air and the water curtain assembly 2, and then improving the net air efficiency of the air cooler.

[0034] In this embodiment, the air inlet 11 is disposed on the outer wall of the housing 1, and the air outlet 12 is disposed at the top of the housing 1. By staggering the air inlet 11 and air outlet 12 on the sidewall and top of the housing 1, the clean air blown out by the air cooler is reduced from being re-inhaled into the air inlet assembly 4, thereby improving the clean air efficiency of the air cooler. By providing a water supply assembly 3 to continuously supply water to the drencher assembly 2, the drencher assembly 2 is kept moist, allowing the drencher assembly 2 to better remove heat from the outside air through evaporative heat absorption. At least three drencher assemblies 2 can be provided based on the cooling requirements of the operating environment, thereby adapting to a wider range of environments. Compared to placing a single drencher assembly 2 at the air inlet 11, the present application encloses at least three drencher assemblies 2 to form an installation space 21, with the fan assembly 4 disposed in the installation space 21. This increases the contact area between the outside air and the drencher assembly 2, thereby improving the heat exchange efficiency between the drencher assembly 2 and the outside air. Driven by the fan assembly 4, the outside air enters the air inlet side of the fan assembly 4 through the air inlet 11 and the water curtain assembly 2 in sequence. During this process, the water on at least three water curtain assemblies 2 can take away the heat from the inhaled outside air by evaporating and absorbing heat, thereby humidifying and dissipating the outside air. The humidified and cooled air is discharged from the air outlet side of the fan assembly 4, thereby cooling the external environment through the humidified and cooled air.

[0035] like Figure 1 As shown, the shell 1 has a first side wall 13 and a second side wall 14 arranged opposite to each other, and a third side wall 15 arranged between the first side wall 13 and the second side wall 14, and the inner sides of the first side wall 13, the second side wall 14 and the third side wall 15 are respectively provided with the water curtain assembly 2, and at least one of the first side wall 13, the second side wall 14 and the third side wall 15 is provided with the air inlet 11.

[0036] In this embodiment, the air inlet 11 can be formed by a plurality of through holes arranged at intervals, the air inlet 11 faces the water curtain assembly 2, and the area of ​​the air inlet 11 is adapted to the area of ​​the wet curtain 22 of the water curtain assembly 2. By arranging the inner sides of the first side wall 13, the second side wall 14 and the third side wall 15 respectively corresponding to the water curtain assembly 2, the position of the air inlet 11 is set relative to the position of the water curtain assembly 2 at least one of the first side wall 13, the second side wall 14 and the third side wall 15, thereby further increasing the heat exchange area between the outside air and the wet curtain 22, and thereby improving the heat exchange efficiency between the water curtain assembly 2 and the outside air.

[0037] like Figure 2 As shown, the first side wall 13 and the second side wall 14 are both provided with the air inlet 11, and the fan assembly 4 includes a volute 41 and a wind wheel 42 rotatably arranged in the volute 41, and the volute 41 is provided with an air inlet 411 on the side facing the first side wall 13 and the side facing the second side wall 14 respectively.

[0038] In this embodiment, the fan assembly 4 may include two volutes 41 and two wind wheels 42 respectively arranged in the two volutes 41, wherein one of the volutes 41 is provided with an air inlet 411 on the side facing the first side wall 13, and the other volute 41 is provided with an air inlet 411 on the side facing the second side wall 14, thereby improving the efficiency of the fan assembly 4 in drawing outside air into the housing 1. The rotation of the two wind wheels 42 creates a negative pressure environment in the housing 1, driving the outside air to enter the two volutes 41 in sequence through the air inlet 11 on the first side wall 13 and the second side wall 14, at least three water curtain assemblies 2, and the two air inlet 411, and then be discharged to the outside through the air outlet 12 of the two volutes 41, so that the outside air evaporates and absorbs heat through the water on the water curtain assembly 2 to form moist and cool air that is discharged to the outside, thereby cooling the environment.

[0039] like Figure 3 As shown, the water curtain assembly 2 includes a wet curtain 22 and a water curtain frame 23, the water curtain frame 23 is connected to the shell 1, the wet curtain 22 is connected to the water curtain frame 23, the water curtain frame 23 has a water inlet side 231 and a water outlet side 232, the water supply assembly 3 is used to supply water to the water inlet side 231 of the water curtain frame 23, and the water outlet side 232 of the water curtain frame 23 is facing the wet curtain 22.

[0040] In this embodiment, in order to facilitate the assembly of the wet curtain 22 to the housing 1, a water curtain frame 23 is provided to connect the housing 1, and the wet curtain 22 is connected to the water curtain frame 23. The water curtain frame 23 can be located above the wet curtain 22, so that the water on the water curtain frame 23 flows to the wet curtain 22 through the water outlet side 232 under the action of gravity, thereby facilitating the water delivered to the water curtain frame 23 by the water supply assembly 3 to flow to the wet curtain 22, thereby keeping the wet curtain 22 in a moist state for a long time, and making it easier for the outside air to exchange heat with the wet curtain 22.

[0041] like Figure 3 As shown, the water curtain frame 23 includes a frame body 233 and a water inlet pipe 2331 provided on the frame body 233 . The water inlet pipe 2331 is provided on the water inlet side 231 , and the water inlet pipe 2331 is located in the middle of the frame body 233 .

[0042] In this embodiment, in order to facilitate the water supply group to supply water to the water curtain frame 23, the water inlet pipe 2331 is arranged on the water inlet side 231, and the water inlet pipe 2331 is located in the middle of the frame body 233, so that the water inlet pipe 2331 can be connected to the water supply component 3 through the pipeline, thereby facilitating the water supply component 3 to transport water to the frame body 233 through the water inlet pipe 2331.

[0043] like Figure 3 and Figure 4 As shown, a clamping portion 2333 is provided on the side of the frame body 233 away from the water outlet side 232 , and the clamping portion 2333 and the peripheral wall of the bottom of the frame body 233 form an installation station 2334 for installing the wet curtain 22 .

[0044] In this embodiment, the frame body 233 further includes mounting portions provided at both ends of the clamping portion 2333. The mounting portions are mounted within the housing 1 via fasteners such as screws or bolts, thereby facilitating removal of the frame body 233 from the housing 1 and improving the stability of the connection between the frame body 233 and the housing 1. A gap may be provided between the clamping portion 2333 and the outlet side 232 so that the clamping portion 2333 cooperates with the outer peripheral wall of the bottom of the frame body 233 to form an installation station 2334. By installing the wet curtain 22 within the installation station 2334, the installation efficiency of the wet curtain 22 is improved, thereby improving the stability of the connection between the wet curtain 22 and the frame body 233.

[0045] like Figure 3As shown, the frame body 233 has a water storage tank 234 and a guide groove 235 connected to the water storage tank 234, the guide groove 235 is arranged in the water storage tank 234, the outlet end of the water inlet pipe 2331 is connected to the middle of the guide groove 235, the frame body 233 has a drainage hole 2332, the drainage hole 2332 is arranged on the water outlet side 232, the outlet end of the drainage hole 2332 faces the wet curtain 22, and the drainage hole 2332 is used to transport the water in the water storage tank 234 to the wet curtain 22.

[0046] In this embodiment, the water supply component 3 can transport water to the guide groove 235 through the water inlet pipe 2331, and the water outlet end of the water inlet pipe 2331 is connected to the middle of the guide groove 235, so that water flows through both sides of the guide groove 235 to the water storage tank 234, and then is transported to the wet curtain 22 through the drainage hole 2332, thereby ensuring the rate at which the water in the frame body 233 flows to the wet curtain 22, so that the water can better soak the wet curtain 22 to reduce water waste.

[0047] In this embodiment, the frame body 233 further includes a water-passing plate disposed on the outlet side 232 of the frame body 233. The water-passing plate has a plurality of drainage holes 2332. The plurality of drainage holes 2332 extend along the length of the outlet side 232 and are located at the same level. Adjacent drainage holes 2332 are spaced evenly apart, thereby ensuring that every portion of the wet curtain 22 along its length is covered by the water-passing plate. This allows the water-passing plate to evenly distribute water to every portion of the wet curtain 22, ensuring the wetted area of ​​the wet curtain 22. The vertical centerline of the drainage holes 2332 can be perpendicular to the bottom wall of the water storage chamber, thereby ensuring that the resistance to water flow and the rate of water flow out of the drainage holes 2332 are optimal.
