[0030] The present invention provides a water curtain device 10 .

[0031] In the embodiment of the present invention, Figures 1 to 8As shown, the water curtain device 10 includes a water curtain frame 100, a water pass plate 200 and a wet curtain 300. The water curtain frame 100 has a water inlet side 110 and a drainage side arranged in the up and down direction; the water pass plate 200 is arranged on the water inlet side 110 of the water curtain frame 100, and the water pass plate 200 has a water pass plate front surface 210a, a water pass plate rear surface 210b, and a water pass plate bottom surface 210c connecting the water pass plate front surface 210a and the water pass plate rear surface 210b. The water pass plate 200 is provided with a plurality of through holes 210, and the through holes 210 penetrate the water pass plate front surface 210a, the water pass plate rear surface 210b and the water pass plate bottom surface 210c, and the aperture of the through holes 210 gradually decreases from the water inlet side 110 toward the drainage side; the wet curtain 300 is installed on the water curtain frame 100 to guide the water passing through the holes 210 to flow into the drainage side.

[0032] The water curtain device 10 includes a water curtain frame 100, which has a water inlet side 110 and a water outlet side arranged in the up-down direction. The water inlet side 110 of the water curtain frame 100 is connected to a water pipe, and the water outlet side is connected to a water tank, so that the water curtain device 10 and the air cooler form a water circulation device.

[0033] like Figures 1 to 6 As shown, the water pass plate 200 is arranged on the water inlet side 110 of the water curtain frame 100, and the water pass plate 200 has a front surface 210a of the water pass plate, a rear surface 210b of the water pass plate, and a bottom surface 210c of the water pass plate connecting the front surface 210a of the water pass plate and the rear surface 210b of the water pass plate. A plurality of through holes 210 are provided on the water pass plate 200, and the through holes 210 penetrate the front surface 210a of the water pass plate, the rear surface 210b of the water pass plate and the bottom surface 210c of the water pass plate, and the aperture of the through holes 210 gradually decreases from the water inlet side 110 toward the drainage side. The through hole 210 penetrates the front surface 210a of the water pass plate, the rear surface 210b of the water pass plate and the bottom surface 210c of the water pass plate. Water enters from the water inlet side 110, passes through the rear surface 210b of the water pass plate through the through hole 210, and flows out from the bottom surface 210c of the water pass plate; the aperture of the through hole 210 gradually decreases from the water inlet side 110 toward the drainage side. In this way, when water flows through the through hole 210, the water will be subjected to a pressure that gradually increases from top to bottom, ensuring that the water flow will flow downward along the extension direction of the through hole 210, ensuring that the water flow direction flows from the water inlet side 110 to the wet curtain 300 and then to the drainage side, thereby improving the utilization rate of water and further improving the cooling effect of the water curtain device 10.

[0034] like Figure 1 , Figure 2As shown, the wet curtain 300 is installed on the water curtain frame 100 to guide the water passing through the hole 210 to flow into the drainage side. The water curtain is installed on the water curtain frame 100. When the water flows through the wet curtain 300 to soak the wet curtain 300, a large amount of water evaporates when the unsaturated air passes through the wet curtain 300, so that the temperature of the air drops, and the fan blows to every corner, causing the temperature to drop rapidly. The wet curtain 300 reaches a medium that can quickly drop the temperature but the cost is not high; in this embodiment, when water passes through the through hole 210 on the water-passing plate 200, it can ensure that the water will flow downward through the extension direction of the hole 210, further ensuring that the water will flow to the wet curtain 300, thereby improving the utilization rate of water, and also ensuring that the wet curtain 300 will be continuously soaked by water, thereby improving the cooling effect.

[0035] The technical solution of the present invention gradually reduces the aperture of the through hole 210 on the water curtain device 10 from the water inlet side 110 toward the discharge side, thereby ensuring that the water flow will flow downward along the extension direction of the through hole 210, and ensuring that the water flow direction flows from the water inlet side 110 to the wet curtain 300, thereby improving the utilization rate of water and further improving the cooling effect of the water curtain device 10.

[0036] In one embodiment of the present invention, Figure 2 As shown, the hole 210 includes a first water outlet section 211 and a second water outlet section 213. The aperture of the first water outlet section 211 gradually decreases from the water inlet side 110 toward the discharge side. The second water outlet section 213 is connected to the end of the first water outlet section 211 and has the same aperture as the end of the first water outlet section 211. The aperture of the first water outlet section 211 gradually decreases from the water inlet side 110 toward the water outlet side 130, and when it decreases to a certain extent, it becomes the aperture of the second water outlet section 213. The apertures of the second water outlet section 213 are all the same. It can be understood that the apertures of the first water outlet section 211 and the second water outlet section 213 can be arranged in a "Y" shape. With this arrangement, when water flows through the through hole 210, the water will be subjected to a pressure that gradually increases from top to bottom, ensuring that the water flow will flow downward along the extension direction of the through hole 210, ensuring that the water flow direction flows from the water inlet side 110 to the wet curtain 300 and then to the drainage side, thereby improving the utilization rate of water and thereby improving the cooling effect of the water curtain device 10.

[0037] In one embodiment of the present invention, Figures 1 to 6As shown, a plurality of through holes 210 extend along the length direction of the drainage side and are located at the same level, and the intervals between two adjacent through holes 210 are the same. A plurality of through holes 210 are provided on the water-passing plate 200, and the plurality of through holes 210 are arranged at the same level and extend along the length direction of the drainage side. The wet curtain 300 is arranged below the water-passing plate 200, and the plurality of through holes 210 are arranged at the same level, which can ensure that each part of the wet curtain 300 along the length direction is covered by the water-passing plate 200, that is, the water-passing plate 200 can evenly flow water to each part of the wet curtain 300, ensure the wetted area of ​​the wet curtain 300, improve the utilization rate of the wet curtain 300, and further improve the cooling effect of the water curtain device 10.

[0038] In one embodiment of the present invention, Figure 1 , Figure 7 As shown, the water inlet side 110 also includes a water storage chamber 111, and the water storage chamber 111 is provided with a water inlet 113. The water pass plate 200 is formed as the front wall of the water storage chamber 111, and the center line of the through hole 210 is perpendicularly arranged to the bottom wall of the water storage chamber 111. The center line of the through hole 210 is perpendicularly arranged to the bottom wall of the water storage chamber 111, that is, the central axis of the water pass plate 200 is perpendicularly arranged to the bottom wall of the water storage chamber 111. Such an arrangement can ensure that the resistance to the water flow and the rate of flowing out through the hole 210 are the most appropriate; when the angle between the center line of the through hole 210 and the bottom wall of the water storage chamber 111 is too small, the water flow will first contact the first water outlet section 211 and flow out from the first water outlet section 211. The direction of the water flow has not changed, and the water flow from the through hole 210 is not changed. The water flows out from the front surface 210a of the plate, and then the water does not flow to the wet curtain 300, and the wetting effect is not achieved, which affects the effect of the water curtain device 10; when the angle between the center line of the through hole 210 and the bottom wall of the water storage chamber 111 is too large, the pressure on the water when passing through the through hole 210 will increase, affecting the speed of the water flow and reducing the flow rate of the water. On the one hand, the wetting effect of the wet curtain 300 is slowed down, and on the other hand, the water storage chamber 111 accumulates too much water, which is easy to cause water leakage. Therefore, the center line of the through hole 210 is arranged vertically with the bottom wall of the water storage chamber 111, which further ensures that the water will flow to the wet curtain 300, improves the utilization rate of water, and improves the cooling effect.

[0039] In one embodiment of the present invention, Figure 1 , Figure 6As shown, the water storage chamber 111 is provided with a guide surface 230, and the guide surface 230 is inclined from the bottom wall of the water storage chamber 111 to the second water outlet section 213 of the through hole 210. The setting of the guide surface 230, on the one hand, when the water flow is small, the water flow can flow directly to the second water outlet section 213, and when flowing through the guide surface 230, because of the setting of the inclined section, the water flow flows downward, and due to the reason of gravity, the water flow can be accelerated, and the water flow through the through hole 210 can be accelerated; on the other hand, when the water flow is large, because the water will be subjected to pressure when flowing through the through hole 210, it will not flow out of the through hole 210 immediately, but will gradually penetrate from the bottom of the through hole 210, so the water will be stored in the inverted triangle space formed by the guide surface 230, the water plate 200, and the bottom wall of the water storage chamber 111, and gradually flow out from the second water outlet section 213 to the bottom of the through hole 210, further ensuring the direction of the water flow and improving the cooling effect of the water curtain device 10.

[0040] In one embodiment of the present invention, Figures 1 to 8 As shown, the lower plate surface of the water-passing plate 200 is aligned with the lower side of the guide surface 230. Such an arrangement is conducive to the water flow getting rid of surface tension, and will not change the direction of the water flow, so that the water keeps flowing downward; when the lower plate surface of the water-passing plate 200 is lower than the lower side of the guide surface 230, and when the water flow is too small, the water will flow to the bottom of the guide surface 230 due to the force after passing through the hole 210, resulting in the water being unable to flow to the wet curtain 300, thereby reducing the wetting effect of the wet curtain 300 and failing to meet the cooling effect. Therefore, the lower plate surface of the water-passing plate 200 is aligned with the lower side of the guide surface 230 to ensure that the water will flow to the wet curtain 300, thereby improving the utilization rate of water and the cooling effect.

[0041] In one embodiment of the present invention, Figure 1 As shown, the drainage side of the water curtain frame 100 also includes a water outlet 131 and a drainage platform 133. The horizontal height of the water outlet 131 is lower than the drainage platform 133. The drainage platform 133 is inclined from the end away from the water outlet 131 toward the water outlet 131. Water flows to the wet curtain 300, most of the water will be absorbed by the wet curtain 300, and the remaining water will continue to flow downward to the drainage side. The function of the drainage side can collect unused water for unified treatment for use in the next device or re-transport the water to the water inlet side 110 for reuse. The drainage platform 133 is inclined from the end away from the water outlet 131 toward the water outlet 131, because water flows into the wet curtain 300 from different directions, and then flows out of the wet curtain 300 from different directions, and there is only one water outlet 131 and it is set on one side of the drainage side. It can be understood that such an inclined setting helps the water flowing out of the far end to flow to the water outlet 131 faster, speeding up the efficiency of collecting water at the water outlet, thereby speeding up the next step of water treatment and improving the working efficiency of the device.

[0042] In one embodiment of the present invention, Figures 1 to 8 As shown, the water curtain frame 100 is provided with a limit buckle 400, and the limit buckle 400 is used to fix the wet curtain 300. The limit buckles 400 are provided on both sides of the water curtain frame 100, and the limit buckles 400 cooperate with the limit components 410. When in use, it is only necessary to take down the limit components 410, install the wet curtain 300 on the water curtain frame 100, and then align the limit components 410 with the limit buckles 400 to install, so as to achieve the fixed installation of the wet curtain 300, improve the installation efficiency of the wet curtain 300, and facilitate the installation and removal of the wet curtain 300.

[0043] In one embodiment of the present invention, the water curtain frame 100 and the water pass plate 200 are an integrated structure. The setting of the integrated structure allows the water curtain frame 100 and the water pass plate 200 to be integrally injection molded in the same set of molds, without using different molds to prepare the water curtain frame 100 and the water pass plate 200 separately, and only one injection molding and demoulding process is required under the same mold to obtain a complete water curtain device 10.

[0044] Furthermore, only one set of molds is needed to prepare the water curtain device 10, which can save molds, save resource investment, and effectively reduce costs.

[0045] The present invention also proposes an air cooler, which includes a water curtain device 10. The specific structure of the water curtain device 10 refers to the above embodiment. Since the air cooler adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0046] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
