[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0032] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0033] like Figure 1 As shown, the existing evaporative cooling pad structure folds the main body 11 to form a folded structure and fixes it with hot melt adhesive lines 2. When water flows downwards, it accumulates at the steps due to the obstruction of the hot melt adhesive lines, resulting in water mist being blown out when the airflow increases. At the same time, due to the compression of the hot melt adhesive lines, the sides near the hot melt adhesive lines are compressed and deformed, further increasing the water accumulation problem. Therefore, the existing structure is optimized to solve the problems of water accumulation and folding deformation.
[0034] Please see Figures 2-10 One embodiment of this utility model proposes a wet curtain structure, including a wet curtain body 1. The wet curtain body 1 is folded at equal intervals to form multiple folded surfaces. The connection between adjacent folded surfaces forms a fold peak 3. The wet curtain body 1 includes an air inlet side and an air outlet side arranged opposite to each other. A fixing net 6 is installed on the air inlet side and the air outlet side of the wet curtain body 1. The fixing net 6 is fixedly connected to the fold peak 3 of the wet curtain body 1.
[0035] The wet curtain body 1 is folded at equal intervals to form a folded structure. Water flows downwards unimpeded, quickly and gradually wetting the entire wet curtain body 1. Because the wet curtain body 1 is folded at equal intervals, the resulting fold peaks 3 are uniform in size and spacing, ensuring consistent water flow rate and speed, thus making the entire wet curtain body more evenly wetted. The folds in the wet curtain body 1 form fold peaks 3, which are fixedly connected to the fold peaks 3 by a fixing net 6. The fixing net 6 supports the wet curtain body 1, preventing deformation of the wet curtain body 1 and the fold peaks 3. Alternatively, the wet curtain body 1 can also be folded at arbitrary intervals to form a folded structure. Water flows downwards unimpeded. However, due to unequal intervals in the folding structure, the water flow rate will vary, resulting in different soaking times for the wet curtain. This design does not affect the overall function of the wet curtain.
[0036] Since the hot melt glue line 2 in the middle of the wet curtain body is cancelled, water flowing from top to bottom is not blocked by extra objects, and the flow is smooth. There is no problem of water accumulation caused by excessive water flow speed or water flow volume. The wetting of the entire wet curtain body is more uniform, thereby solving the deformation of the fold peak 3 caused by the extrusion of the hot melt glue line 2 in the traditional method, eliminating the problem of water accumulation at the hot melt glue line 2, and solving the problem of water mist blowing out.
[0037] By optimizing the structure of the wet curtain, the problem of water mist blowing out caused by water accumulation and fold peak 3 deformation under the condition of increased air volume is solved, and the use amount of hot melt glue is greatly reduced, thereby reducing the cost.
[0038] In a specific embodiment, the fixed net 6 is bonded to the fold peak 3 of the wet curtain body 1.
[0039] In the above example, the function of the fixed net 6 is to cancel the hot melt glue line 2, and then to bond the fixed net 6 to the fold peak 3 after single-sided glue coating. A plurality of locking points are formed between the fixed net 6 and the fold peak 3, and the locking points are mutually pulled to prevent the distance between the adjacent two fold peaks 3 from changing or the fold peak 3 from deforming, thereby maintaining the stability of the distance between the fold peaks 3.
[0040] As shown in Figure 2 and Figure 3 , the fixed net 6 has a honeycomb structure.
[0041] In the above example, the fixed net 6 has a uniform planar honeycomb structure, and the plurality of locking points are mutually pulled and restricted to disperse the stress, and the mutual pulling and restriction between each locking point can prevent the fold peak 3 from deforming.
[0042] In another example, the distance between each adjacent two fold peaks 3 is 3.3 mm-5.5 mm.
[0043] In a specific application example, the wet curtain body 1 further includes four side surfaces connected between the air inlet side and the air outlet side, and each of the four side surfaces is bonded with a non-woven fabric.
[0044] In the above example, the non-woven fabric has permeability, and water can be transported to the wet curtain body through the non-woven fabric.
[0045] As shown in Figure 4 , the four side surfaces include two long side surfaces and two short side surfaces, the two long side surfaces are bonded with long side non-woven fabrics 4, and the two short side surfaces are bonded with short side non-woven fabrics 5.
[0046] As shown in Figure 5As shown, water leaks from above to the long-side non-woven fabric 4, and then flows down along the wet curtain body after the long-side non-woven fabric 4 is wetted. The whole machine air blows in the direction of the arrow, and the air passes through the wet curtain body to bring water molecules into the air to form humidification.
[0047] In another example, the mesh of the fixed net 6 is hexagonal, pentagonal, triangular, quadrangular or circular.
