The fins not only increase the heat exchange area, but also further improve the heat exchange efficiency through the convex design on their surface. The convexity can form vortices and increase the turbulence of the fluid on the fin surface, thereby improving the heat transfer coefficient.

[0021] The monitoring and alarm module is a component in the heat exchange device used to detect the fluid status in real time and trigger the alarm signal. Through data collection, data analysis and alarm signal generation steps, it ensures that the system can issue an alarm in time when the fluid status is abnormal, thereby avoiding potential safety hazards and efficiency losses; The data acquisition unit is the first component of the monitoring and alarm module. Its function is to receive real-time data from temperature sensors, pressure sensors and flow sensors. The data acquisition unit transmits the data of these sensors to the data analysis unit through wired or wireless means for further processing; The data analysis unit is the core part of the monitoring and alarm module. It is responsible for receiving the data transmitted by the data acquisition unit and conducting in-depth analysis and processing. By comparing the preset normal range value with the real-time data, the data analysis unit can determine whether the fluid state is within the normal range.

[0022] Embodiment 2: A finned winding tube with high heat exchange strength, wherein the materials of the base tube outer layer, the base tube intermediate layer one, the base tube intermediate layer two and the base tube inner layer are TC4 titanium alloy, 7075 aluminum alloy, 321 stainless steel and copper alloy respectively.

[0023] The inner diameter of the inner layer of the base tube is 7.93 mm, the diameter of the outer layer of the base tube is 80.656 mm, the winding spacing of the fins is 69 mm, and the height of the fins is 3 mm.

[0024] Furthermore, TC4 titanium alloy has high strength, low density and good corrosion resistance. Its tensile strength and yield strength are well maintained at high temperatures. As the outer layer of the base pipe, the corrosion resistance of TC4 titanium alloy can ensure the long-term stable operation of the winding pipe in harsh environments. At the same time, its high strength and good ductility help to withstand fluid pressure and external loads. 7075 aluminum alloy is a cold-treated forged alloy with high strength, far superior to mild steel, compact structure, strong corrosion resistance, good mechanical properties and anodic reaction characteristics. As the intermediate layer of the base tube, the high strength and good mechanical properties of 7075 aluminum alloy help to enhance the stability and durability of the overall structure. At the same time, its corrosion resistance also helps to extend the service life of the winding tube; 321 stainless steel is a titanium-containing austenitic stainless steel with good resistance to intergranular corrosion, especially in high temperature environments. In addition, it also has good processing and welding properties. As the second intermediate layer of the base tube, the intergranular corrosion resistance of 321 stainless steel can ensure that the spiral tube maintains stable heat exchange performance under harsh conditions such as high temperature and high pressure. At the same time, its good processing and welding properties also help to improve the manufacturing quality and reliability of the spiral tube; Copper alloy has relatively high electrical and thermal conductivity, which makes it widely used in electrical and heat exchange applications. In addition, copper alloy has good corrosion resistance and wear resistance. As the inner layer of the base tube, the high thermal conductivity of copper alloy can significantly improve the heat exchange efficiency and ensure that the fluid can effectively transfer heat during the flow process. At the same time, its good corrosion resistance and wear resistance also help to extend the service life of the spiral tube. The inner diameter of the base tube determines the flow velocity and flow rate of the fluid in the pipeline. A smaller inner diameter can increase the flow velocity of the fluid, thereby improving the heat exchange efficiency. However, a too small inner diameter will also increase the flow resistance of the fluid and reduce the overall efficiency of the system. Therefore, the inner diameter of the base tube is selected to be 7.93mm, which can ensure a higher flow velocity without causing excessive flow resistance. The diameter of the outer layer of the base tube determines the overall size and surface area of ​​the winding tube. A larger diameter can increase the surface area, thereby improving the heat exchange efficiency. However, an excessively large diameter will also increase the volume and weight of the equipment, increase the manufacturing cost and transportation difficulty. Therefore, the diameter of the outer layer of the base tube is selected to be 80.656mm, which can ensure a sufficiently large surface area to improve the heat exchange efficiency without causing the equipment to be too large in volume and weight. The winding pitch of the fins determines the distribution density and surface area of ​​the fins on the pipe. Appropriate spacing can increase the surface area of ​​the fins, thereby improving the heat exchange efficiency. However, too dense spacing will also increase the flow resistance and reduce the overall efficiency of the system. Therefore, the winding pitch of the fins is selected to be 69mm, which can ensure that the fins have sufficient distribution density to improve the heat exchange efficiency without causing excessive flow resistance. The height of the fin determines the contact area and heat transfer efficiency between the fin and the fluid. Higher fins can increase the contact area, thereby improving the heat transfer efficiency. However, too high fins will also increase the flow resistance and reduce the overall efficiency of the system. In addition, the height of the fin is 3mm, which can ensure sufficient contact area to improve the heat transfer efficiency without causing excessive flow resistance or affecting the winding tube structure.

Through the decision tree, the most appropriate control strategy is selected according to the current parameter state. The control strategy selection unit also includes a strategy library, which stores a variety of predefined control strategies.

[0031] Furthermore, the fault feature extraction unit first receives real-time data from the temperature sensor, pressure sensor and flow sensor, which are direct reflections of the operating status of the heat exchanger.

Meanwhile, independent source signals are separated from the mixed signal by independent component analysis, and these source signals can better reflect the fault characteristics of the heat exchanger. Based on the results of signal processing, characteristic information related to the fault is extracted, including frequency peak, amplitude change and phase difference, etc. These characteristic information will be used as input for the subsequent fault diagnosis algorithm.
