[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 To achieve the above objectives, this utility model discloses the following technical solution: a heat dissipation component for a cooling tower, comprising a cooling tower body 1, a heat exchange coil 2, and combined heat dissipation fins 3. The cooling tower body 1 houses the heat exchange coil 2. Several combined heat dissipation fins 3 are installed on each straight section of the heat exchange coil 2. Each combined heat dissipation fin 3 includes a first heat dissipation fin 7 and a second heat dissipation fin 8. A splicing interface 9 is provided at one opposite end of each of the first and second heat dissipation fins 7 and 8. The splicing interface 9 is semi-circular, allowing for better adaptation to the heat exchange coil 2. The first and second heat dissipation fins 7 and 8 are snapped together on both sides of the heat exchange coil 2 via the splicing interface 9. Connecting plates 10 are installed in front of and behind the first heat dissipation fin 7 and in front of and behind the second heat dissipation fin 8. Threaded holes 12 are provided on the connecting plates 10. Bolts 11 are installed in the threaded holes 12 of the two connecting plates 10 opposite to the first heat dissipation fin 7 and the second heat dissipation fin 8. This design allows the heat dissipation fins to be detachable, facilitating individual replacement after damage or reaching the end of their service life, making maintenance more convenient and reducing operating costs. A cooling fan 5 is installed on the top of the cooling tower body 1. A flow guiding structure 4 is provided above the heat exchange coil 2. The flow guiding structure 4 is fixedly connected to the inner wall of the cooling tower body 1. A spray system 6 is provided above the flow guiding structure 4. The spray system 6 is a supporting system for the cooling tower and will not be described in detail here.

[0022] Specifically, the side of the combined heat dissipation fin 3 is S-shaped.

[0023] In this embodiment, the S-shaped design allows the combined heat dissipation fins 3 to have a larger cross-section, enabling them to come into contact with more sprayed water, thereby improving heat absorption efficiency.

[0024] Specifically, the length of the combined heat dissipation fins 3 gradually decreases from the middle of the straight section of the heat exchange coil 2 towards both ends.

[0025] In this embodiment, the combined heat dissipation fins 3 are designed to be compatible with the airflow guiding structure 4.

[0026] Specifically, the cross-section of the flow guiding structure 4 is an equilateral triangle.

[0027] In the embodiment, the guide structure 4 is designed to guide the spraying water from the edge of the cooling tower to the middle and guide the air flow drawn from the outside to the middle of the cooling tower, so as to better take away the heat in the tower.

[0028] Specifically, the upper and lower layer combined heat dissipation fins 3 are distributed in space staggered.

[0029] In the embodiment, the staggered distribution can make the heat dissipation fins more fully contact with the spraying water, so that the utilization rate of the spraying water is higher.

[0030] Specifically, the length of the longest combined heat dissipation fin 3 on the heat exchange coil 2 is equal to the inner ring port diameter of the guide structure 4.

[0031] In the embodiment, such design can avoid the heat dissipation fins being covered by the guide structure 4 and unable to exchange heat with the spraying water, and ensures the rationality of the design.

[0032] The working principle and use process of the utility model are as follows: in use, the medium to be cooled enters the heat exchange coil 2, the heat inside the heat exchange coil 2 is dissipated outward through the heat exchange coil 2 itself and also dissipated outward through the combined heat dissipation fin 3 installed on the heat exchange coil 2, so that the medium is cooled, at the same time, the water sprayed by the spraying system 6 falls on the heat exchange coil 2 and the combined heat dissipation fin 3 to absorb heat, further cooling the medium in the heat exchange coil 2, and the water sprayed by the spraying system 6 outside the combined heat dissipation fin 3 is guided by the guide structure 4 and flows towards the combined heat dissipation fin 3, so that more spraying water participates in heat absorption.

[0033] It should be noted that in this text, terms such as "including", "containing" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment. Without more limitations, the element defined by the statement "including a" does not exclude the presence of another identical element in the process, method, article or equipment including the element.

[0034] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
