Description

Technical Field

[0001] This utility model relates to the technical field of water-collecting and defogging packing sheets, and in particular, to a defogging module that is easy to produce efficiently and reliably. Background Technology

[0002] A cooling tower is a heat exchange device. During operation, hot water is sprayed onto the surface of the packing material, where it comes into contact with cold air flowing upwards through the packing. Heat exchange occurs between the hot water and the cold air, causing some of the hot water to evaporate and eventually be released into the outside atmosphere. On the one hand, the evaporated hot water discharged from the tower results in a significant water loss. On the other hand, especially during cold winters, the air flowing out of the tower is saturated and warm, so when this air comes into contact with the cold air outside the tower, it produces a large amount of mist, which can affect the surrounding environment and traffic.

[0003] To alleviate the above problems, some manufacturers install a defogging module below the air outlet of the cooling tower. The defogging module is composed of multiple packing plates connected in sequence, forming channels between the packing plates. Before the saturated hot and humid air flows out of the air outlet to the outside of the tower, it passes through the channels, allowing the saturated hot and humid air to come into contact with the packing plates. This causes some water droplets in the air to condense and adhere to the packing plates, thus saving water and reducing the formation of mist.

[0004] In commercially available anti-fogging modules, the packing sheets are typically bonded together using adhesives. This method can lead to decreased bond strength due to adhesive aging or failure, affecting the module's stability, durability, and reliability. Furthermore, the adhesive bonding process requires a long curing time, hindering efficient production. Additionally, the relatively high flow rate of saturated humid air passing through these channels prevents sufficient contact between the air and the packing sheets, resulting in lower water absorption efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to overcome the above-mentioned defects in the prior art, a highly efficient and reliable defogging module is provided.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a high-efficiency production and reliable defogging module, including two stacked packing sheets, each of the two packing sheets having a corresponding protrusion on its opposite surface, the two corresponding protrusions being fixed by high-frequency welding, a positioning structure being provided between the two corresponding protrusions, an air passage being formed between each pair of adjacent protrusions, the air passage having a curved structure, and at least one of the surfaces of the two corresponding protrusions that are close to each other having a recess, the recess being offset from the positioning structure, and the recess being connected to the air passages on both sides of the protrusion.

[0007] Furthermore, each of the two corresponding protrusions is provided with a recessed portion, which is a groove recessed on the protrusion. The grooves on the two protrusions are aligned with each other, and the two grooves together form an air passage gap that communicates with the air passages on both sides.

[0008] Furthermore, multiple water-blocking strips are provided on the packing sheet between each of the two adjacent protrusions.

[0009] Furthermore, the water-blocking strip is bent.

[0010] Furthermore, the positioning structure includes a positioning protrusion and a positioning groove, the positioning protrusion and the positioning groove cooperating with each other, and the positioning protrusion and the positioning groove are respectively disposed on the two corresponding protrusions.

[0011] Furthermore, each of the protrusions is provided with a positioning protrusion and a positioning groove, the positioning protrusion and the positioning groove being respectively located at opposite ends of the protrusion.

[0012] Furthermore, the positioning protrusion is a frustum conical structure, and the positioning groove is a conical groove structure.

[0013] The beneficial effects of this utility model are as follows: This utility model provides a highly efficient and reliable defogging module. The two stacked packing sheets are fixedly connected by high-frequency welding, avoiding the problems of low connection stability and lack of durability caused by adhesive aging and failure in traditional connection methods. Furthermore, it eliminates the need to wait for the adhesive to dry, enabling rapid and continuous processing, greatly improving production efficiency. Compared to adhesive connections, high-frequency welding produces less pollution and is more environmentally friendly. Additionally, the recessed portion on the raised strip intensifies the mixing of airflow within the air passage. This slows down the airflow velocity and allows the airflow to fully contact the packing sheets, resulting in more water droplets adhering to the packing sheets and reducing moisture loss.

[0021] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] Please see Figures 1-5 This utility model provides an efficient and reliable defogging module, including two stacked packing sheets 1. Each of the two packing sheets 1 has a raised strip 11 on its opposite surface. The raised strips 11 on the two packing sheets 1 correspond one-to-one. Corresponding raised strips 11 are fixed together by high-frequency welding. A positioning structure is provided between corresponding raised strips 11. An air passage 101 is formed between each pair of adjacent raised strips 11. The air passage 101 has a curved structure. Recesses 102 are provided on the surfaces of the two adjacent raised strips 11. The recesses 102 are offset from the positioning structure and are connected to the air passages 101 on both sides of the raised strips 11.

[0023] This utility model's efficient and reliable defogging module is applied inside a cooling tower. In use, the air passage 101 is arranged vertically. Saturated, hot, humid air flowing upwards through the packing material inside the cooling tower enters the defogging module from the bottom of the air passage 101, passes through the top of the air passage 101, and finally flows out of the cooling tower through the air outlet at the top. As the airflow moves within the defogging module, the air passage 101 defines the airflow direction, allowing the airflow within each air passage 101 to move essentially along its own flow path, ensuring that the airflow as a whole can smoothly pass through the air passage 101 from bottom to top. As the airflow moves along the air passage 101, some of the airflow will flow into the adjacent air passage 101 through the recess 102. The airflow passing through the recess 102 will cause a certain degree of impact on the airflow in the air passage 101, thereby intensifying the mixing of the airflow in the air passage 101. On the one hand, it slows down the flow speed of the airflow in the air passage 101, and on the other hand, it allows the airflow flowing through the air passage 101 to fully contact the packing sheet 1, so that more water droplets in the airflow adhere to the packing sheet 1, thereby reducing moisture loss.

[0024] Furthermore, the efficient and reliable defogging module of this invention utilizes high-frequency welding during processing to generate eddy currents at the protrusions 11 of the packing sheet 1. This causes the contact surfaces of the two protrusions 11 to rapidly reach their melting temperature, and then pressure is applied to bond them together. This method creates a strong weld, ensuring a tight connection between the two packing sheets 1, and eliminates the need for prolonged cooling, enabling rapid and continuous production and significantly improving production efficiency.

[0025] The positioning structure is used to quickly position the two filler pieces 1 before high-frequency welding to ensure that the protrusions 11 are aligned with each other. In this embodiment, the positioning structure includes a positioning protrusion 21 and a positioning groove 22. The positioning protrusion 21 and the positioning groove 22 cooperate with each other. The positioning protrusion 21 and the positioning groove 22 are respectively set on the two corresponding protrusions 11. During installation, the two filler pieces 1 are stacked and the positioning protrusion 21 and the positioning groove 22 are connected. At this time, the two protrusions 11 to be welded are in contact with each other to facilitate subsequent high-frequency welding operations.

[0026] In a preferred embodiment, each protrusion 11 is provided with a positioning protrusion 21 and a positioning groove 22, which are respectively located at opposite ends of the protrusion 11. Thus, the two opposing protrusions 11 are positioned together by the two positioning structures. During actual manufacturing, when the two opposing protrusions 11 are fixedly connected in place by high-frequency welding, the positioning protrusion 21 and the corresponding positioning groove 22 are also fitted into place.

[0027] In addition, the positioning protrusion 21 is a truncated cone structure and the positioning groove 22 is a conical groove structure. The conical structure of the positioning protrusion 21 and the positioning groove 22 facilitates the interlocking and mating between the two, greatly increasing the error tolerance of the two packing pieces 1 when the user installs them, making the installation simpler.

[0028] In this embodiment, the recess 102 is a groove recessed into the protrusion 11. After the two corresponding protrusions 11 on the two packing pieces 1 are fixed by high-frequency welding, the grooves on the two protrusions 11 are aligned with each other, and the two grooves together form an air passage gap communicating with the air passage channels 101 on both sides. In other embodiments, the recess 102 may be provided on only one of the protrusions 11. In this case, after the two corresponding protrusions 11 on the two packing pieces 1 are fixed by high-frequency welding, a single recess 102 forms an air passage gap. Therefore, in specific implementation, it is sufficient that at least one surface on the surface where the two corresponding protrusions 11 are close to each other is provided with a recess 102. In addition, the flow area of ​​the air passage gap is much smaller than the flow area of ​​the air passage channel 101 to ensure that the airflow can smoothly pass through the air passage channel 101.

[0029] In this embodiment, the protrusion 11 is generally V-shaped, which makes the air passage 101 a bent V-shaped passage structure. Compared with a straight passage, the bent air passage 101 can extend the airflow path and increase the contact time between the airflow and the packing sheet 1, thereby helping to trap more moisture in the airflow.

[0030] Multiple water-blocking strips 12 are provided on the packing sheet 1 between each pair of adjacent protrusions 11. In this embodiment, the water-blocking strips 12 are bent. The water-blocking strips 12 can increase the surface area of ​​the packing sheet 1, thereby increasing the contact area between the airflow and the packing sheet 1, which is beneficial for trapping more moisture.

[0031] The packing sheet 1 is a one-piece molded structure. The packing sheet 1 can be made of plastic or metal materials, and there is no limitation here.

[0032] This utility model presents a highly efficient and reliable defogging module. Two stacked packing sheets 1 are fixedly connected by high-frequency welding, avoiding the problems of low connection stability and lack of durability caused by adhesive aging and failure in traditional connection methods. Furthermore, it eliminates the need to wait for adhesive to dry, enabling rapid and continuous processing, significantly improving production efficiency. Compared to adhesive connections, high-frequency welding produces less pollution and is more environmentally friendly. Additionally, the recessed portion 102 on the protrusion 11 intensifies the mixing of airflow within the air passage 101. This slows down the airflow velocity within the passage and allows for sufficient contact between the airflow and the packing sheets 1, resulting in more water droplets adhering to the packing sheets 1 and reducing moisture loss.

[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
