[0002] Cooling water energy-saving circulation devices are widely used in industrial cooling, air-conditioning systems and other fields, aiming to improve the efficiency of cooling systems, reduce energy consumption and waste of water resources. With the acceleration of industrialization, the demand for high-efficiency cooling equipment is growing. Although traditional cooling systems can meet basic cooling needs, they have problems such as high energy consumption and low water resource utilization in actual applications, which seriously affect production efficiency and environmental protection. In order to cope with the above problems, existing technical solutions usually adopt a variety of methods to optimize the performance of cooling systems. Among them, common means include using efficient heat exchangers, adjusting water flow velocity, improving pipeline design, etc. For example, by increasing the heat exchange area and improving fluid flow characteristics, the heat transfer efficiency can be effectively improved; by reasonably arranging pipelines, reducing elbows and resistance points, reducing water pressure loss, and further saving energy; in addition, the heat exchanger and pipeline can be cleaned regularly to maintain their good working condition and extend their service life. However, these conventional means still have certain limitations in practical applications. Especially when the cooling temperature needs to be precisely controlled, traditional cooling systems often find it difficult to achieve precise energy management, which easily leads to excessive or insufficient water supply, thereby affecting the working stability and efficiency of the cooled mechanism.
