Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning equipment, and in particular to a wet film anti-splashing structure for evaporative energy-saving equipment. Background Technology
[0002] The principle of wet film cooling is to absorb heat from the air through the evaporation of water, thereby achieving a cooling effect. Wet film cooling systems utilize the characteristic that water absorbs a large amount of heat energy during evaporation, lowering the air temperature through the evaporation of water on the surface of the wet film.
[0003] Specifically, when hot air passes through the wet film, the moisture on the surface of the wet film evaporates, absorbing heat from the air, thus lowering the air temperature and simultaneously lowering the water temperature.
[0004] Conventional wet film cooling equipment is usually used to cool the air. The wet film only needs to be wetted. In addition, the wet film itself is hygroscopic, so water splashing usually does not occur.
[0005] Evaporative cooling equipment used for cooling water (similar in function to cooling towers) typically requires a certain volume of water to achieve the desired heat exchange effect.
[0006] When the water volume is too large and the wet film cannot absorb it, cooling water will fly out along the wet film channel, resulting in water splashing.
[0007] In addition, the fan may also carry out a small amount of water droplets, resulting in water splashing. Severe water splashing can cause adverse consequences such as slippery ground, equipment rusting, long-term dampness leading to bacterial growth, water waste, and increased energy consumption. Utility Model Content
[0008] The main purpose of this invention is to propose a wet film anti-splashing structure for evaporative energy-saving equipment, which aims to avoid the splashing problem of traditional evaporation tower equipment, prevent bacterial growth and water waste, and significantly improve the efficiency, service life and reliability of the equipment.
[0009] To achieve the above objectives, this utility model proposes a wet film anti-splashing structure for evaporative energy-saving equipment.
[0010] include:
[0011] The tower body has a hollow cavity, and a fan assembly is provided at the top of the tower body;
[0012] The heat exchange components are arranged in a rectangular pattern on the inner wall of the tower, forming an evaporation channel.
[0013] The heat exchange assembly includes a frame and a wet film disposed within the frame. The inner and outer walls of the wet film are respectively an air inlet and an air outlet, and the air outlet is connected to an evaporation channel.
[0014] The frame includes a bottom support plate and a rear side plate extending upward from the rear end of the bottom support plate. The bottom support plate gradually slopes downward from the outside to the inside.
[0015] And make the wet film at a predetermined tilt angle,
[0016] The wet film is composed of several sheets that are tilted at 45 degrees and crossed.
[0017] A water pump, wherein the pumping end is located at the bottom of the tower body, and the pump outlet is provided with a deluge pipe located above the wet film.
[0018] By improving the tilt angle of the bottom support plate and forming a wet film with 45-degree cross-tilted plates, a larger contact surface can be formed when the rain spray pipe sprays onto the top wall of the wet film. At the same time, the coolant can flow inward, thereby reducing liquid splashing outward and improving the wetting effect of the wet film. In other words, the surface of the wet film can have more stable contact with the liquid. That is, the anti-splashing effect is achieved by the predetermined tilt angle.
[0019] Because of the inward tilt angle of the wet film and the inward airflow of the fan, water does not easily flow directly out of the wet film. This ensures that the wet film remains moist, improves evaporation efficiency, and effectively avoids water splashing from the wet film. Attached Figure Description

[0037] like Figures 1 to 5 As shown, a wet film anti-splashing structure for an evaporative energy-saving device includes:
[0038] Tower body 1, wherein the tower body 1 is provided with a hollow cavity, and a fan assembly 10 is provided on the top of the tower body 1;
[0039] The heat exchange components are arranged in a rectangular pattern on the inner wall of the tower body 1, forming an evaporation channel 2.
[0040] The heat exchange assembly includes a frame 20 and a wet film 21 disposed within the frame 20. The inner and outer walls of the wet film 21 are respectively an air inlet 41 and an air outlet 42, and the air outlet 42 is connected to the evaporation channel 2.
[0041] The frame 20 includes a bottom support plate 22 and a rear side plate 23 extending upward from the rear end of the bottom support plate 22. The bottom support plate 22 gradually slopes downward from the outside to the inside.
[0042] And make the wet film 21 tilt at a predetermined angle.
[0043] The wet film 21 is composed of several sheets that are tilted at 45 degrees and crossed.
[0044] Water pump 3, the water pump 3 is located at the bottom of tower body 1, the water pump 3 is provided with a rain pipe 30 at the water outlet, the rain pipe 30 is located above the wet film 21.
[0045] By improving the tilt angle of the bottom support plate 22 and forming a wet film 21 by 45-degree cross-tilted plates, a larger contact surface can be formed when the rain pipe 30 sprays onto the top wall of the wet film 21. At the same time, the coolant can flow inward, thereby reducing liquid splashing outward and improving the wetting effect of the wet film 21. That is, the surface of the wet film 21 can have more stable contact with the liquid, and the anti-splashing effect is achieved by the predetermined tilt angle.
[0046] The inward tilt angle of the wet film 21 and the inward airflow of the fan prevent water from flowing directly out of the wet film 21. This ensures that the wet film 21 remains moist, improves evaporation efficiency, and effectively avoids water splashing from the wet film 21.
[0047] Specifically, the rear side plate 23 is provided with an inwardly inclined first baffle 71, which abuts against the side wall of the wet film 21. In actual design, the wet film 21 has a degree of deformation. Therefore, when tilted, the wet film 21 may cause local compression deformation of the holes. The setting of the first baffle 71
[0048] In this embodiment of the invention, an exchange channel 5 with an expanding diameter from bottom to top is provided between the inner wall of the tower body 1 and the wet film 21. During the heat exchange process, the upper part is liquid and the lower part is heated liquid. Since the liquid particles in the upper part are larger, increasing the inner diameter of the upper exchange channel 5 improves the uniformity of fluid distribution.
[0049] The larger the particles, the lower the fluid pressure. Therefore, the enlarged exchange channel 5 can ensure a consistent fluid flow rate throughout the wet film 21.
[0050] Specifically, the bottom support plate 22 has an inclination angle of 0.5 degrees to 3 degrees. If the inclination angle is too small, the rebound direction of the water droplets will still tend to be outward. If the inclination angle is too large, the wet film 21 will be squeezed and deformed too much, resulting in uneven local flow distribution of liquid.
[0051] Specifically, adjustments can be made based on the support level of the wet film 21.
[0052] In this embodiment of the invention, the bottom of the tower body 1 is provided with an inwardly extending support portion 6, which is fixed to the bottom wall of the outer side of the bottom support plate 22. This allows for the tilting of the bottom support plate 22 without altering the existing design, reducing the overall improvement cost. The tilted wet film 21 also facilitates easier removal for after-sales maintenance, improving the convenience of maintenance and replacement.
[0053] Specifically, the bottom support plate 22 is provided with a matrix of drainage holes 8, which, through a predetermined tilt angle, also allow for smoother liquid drainage.
[0054] In this embodiment of the utility model, the outer side of the bottom support plate 22 is provided with an outwardly inclined second baffle 72, which serves to receive the water and prevent it from splashing onto the outside of the tower body 1 during the falling process.
[0055] Specifically, the wet film 21 is provided with an internal flow channel, which is inclined at 45 degrees.
[0056] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
