Description
Technical Field
[0001] The present application relates to the technical field of cooling towers, and in particular to a combined dry-wet cooling tower. Background Art
[0002] Traditional cooling towers usually operate in a single mode, mainly in two forms: pure wet and pure dry. For traditional wet cooling towers, coils (usually made of stainless steel), fillers, fans and other components are generally used to form the core structure. During operation, circulating water is sprayed on the surface of these stainless steel coils through the upper extension pipe to achieve the effect of heat exchange, and the remaining water is collected by the water tank placed below to complete the entire process. Although this type of structure occupies a certain share in the market and has relatively mature application cases, it still exposes many limitations in the long run - excessive water consumption and large land area. As the concept of energy conservation and emission reduction is deeply rooted in the hearts of the people and driven by the demand for technological progress, the market calls for the emergence of a new generation of more efficient and environmentally friendly composite functional cooling equipment, prompting researchers to continuously explore more advanced design concepts and manufacturing processes to improve this situation.
[0003] Some existing solutions, such as increasing or adjusting the number and position of internal components, attempt to expand the heat exchange interface; on the other hand, some people focus on the research and development of new materials and hope to use the special properties of thermal conductive materials to enhance the heat transfer rate and reduce unnecessary energy loss. However, these two paths fail to fundamentally solve the problem and may introduce new complexity and cost issues. Summary of the invention

Compared with pure dry cooling and pure wet cooling, it can achieve dry-wet switching or synchronous operation of dry and wet conditions. Compared with pure wet cooling towers, it can narrow the operating range, shorten the wet operation time, and achieve energy saving. Specifically, the box design not only bears the weight of the overall components, but also has an integrated container, which can effectively collect the liquid generated by the atomization mechanism, reducing the additional space occupied. The first heat dissipation mechanism and the second heat dissipation mechanism are responsible for dry and wet cooling respectively, which improves the adaptability and flexibility of the system and can perform optimal performance under different working conditions. The atomization mechanism is installed toward the second heat dissipation mechanism and sprays cold water, realizing an efficient wet heat exchange process, increasing the number of droplets in contact with the air per unit time, and accelerating the speed of evaporation and cooling. The design of the container allows one end of the second heat dissipation mechanism to be immersed in the liquid, further enhancing the heat exchange effect, using low-temperature liquid to pre-cool the high-temperature gas near the air inlet, and improving the energy conversion efficiency of the overall device. The above solution effectively solves the problems of high energy consumption and large footprint of traditional cooling towers, significantly improves cooling efficiency and energy efficiency ratio, and reduces operating costs.

The box body 1 has a receiving portion 11, which is integrally formed with the box body 1. One end of the second heat dissipation mechanism 3 is located in the receiving portion 11, and the receiving portion 11 is used to receive the liquid.
[0032] Specifically, the first heat dissipation mechanism 2 includes a first tube core component 21, a second tube core component 22 and a first power component 23, both of which are obliquely installed in the box body 1 and combined into a V-shaped structure.

[0063] A blocking portion 332 is provided on one end where multiple groups of rectifier plates are connected to the rectifier frame. The blocking portion 332 is specifically a stop plate. When the first power member 23 and the second power member 33 are working, the stop plate on each group of rectifier plates abuts against the stop plate on another group of rectifier plates. The swing angle range of the multiple groups of rectifier plates is 90° to 110°. This range of angles can effectively guide the airflow and reduce the probability of turbulence, thereby improving the ventilation performance.
[0064] The plurality of rectifier plates are provided with flow stabilizing portions 333 for further stabilizing the airflow. The flow stabilizing portions 333 are specifically concave flat grooves. By providing the concave flat grooves, the airflow rate is increased and the airflow is stabilized, thereby reducing the probability of turbulence.
[0065] The rectifying part 331 adopts a plate-like structure. When the first power member 23 and the second power member 33 are not working, the air passage is closed to block the entry of large particles and debris. When working, it can effectively guide the airflow and reduce the probability of turbulence, thereby effectively improving the ventilation performance and heat exchange efficiency.
