[0012] Preferably, a connecting flange is provided on one side of the liquid outlet pipe, and the connecting flange and the liquid outlet pipe are welded together.

[0013] Beneficial effects

[0014] In this invention, an annular groove is installed around the fins. The annular groove can firmly fix the fins in a specific position, preventing the fins from shifting due to the impact force or vibration generated by fluid flow during heat exchanger operation. This ensures that the fins are always in the optimal heat exchange position and maintain a stable heat exchange effect. At the same time, the connection between the groove and the fin is equivalent to adding an extra support structure to the fins, allowing the fins to better distribute the force when subjected to pressure and stress, reducing the possibility of fin deformation or damage, thereby improving the overall strength and reliability of the heat exchanger structure. The annular groove can also guide and turbulent the fluid flowing through the fins, making the fluid more evenly distributed around the fins, increasing the contact area and contact time between the fluid and the fins, enhancing the convective heat transfer process, and improving heat exchange efficiency.

[0015] In this invention, a first positioning ring and a second positioning ring are respectively provided on both sides of the sliding tube. Positioning bolts are respectively provided on the surface of the first and second positioning rings. These positioning bolts, in conjunction with the positioning bolts, prevent axial rotation or circumferential displacement of the sliding tube during installation, ensuring that the direction of the sliding tube is strictly fixed according to design requirements. This helps to ensure the correct flow direction and path of the fluid within the tube, optimizing the heat exchange process. Meanwhile, the operating conditions of the heat exchanger, such as the temperature, flow rate, and velocity of the hot and cold fluids, are constantly changing. Adjustable fin spacing allows the heat exchanger to optimize the fluid flow state and heat exchange effect between the fins by changing the fin spacing according to specific operating conditions. For example, in power plants, the fin spacing can be adjusted according to the ambient temperature and power generation load in different seasons to ensure that the heat exchanger in the condenser always maintains high-efficiency heat exchange performance.

[0016] In this invention, recesses are provided on the surface of the fins, increasing the contact area between the fins and the fluid. According to the principles of heat transfer, increasing the heat exchange area helps improve heat transfer efficiency, enabling the heat exchanger to achieve more efficient heat exchange within the same volume and space. When the fluid flows over the surface of the fins with recesses, the recesses disrupt the fluid boundary layer, generating more eddies and turbulence. This turbulence accelerates heat transfer within the fluid, reduces thermal resistance, increases the convective heat transfer coefficient, and thus enhances the overall heat transfer performance of the heat exchanger.

Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0026] Reference Figure 1-4A novel finned heat exchanger includes a heat exchange tube 1. A first positioning ring 5 is provided on one side of the heat exchange tube 1, and a second positioning ring 6 is provided on the other side. Five positioning bolts 4 are provided on the surface of the second positioning ring 6, and the five positioning bolts 4 are threadedly connected to the surface of the second positioning ring 6. A sliding tube 2 is provided on one side of the heat exchange tube 1, and fins 12 are provided on one side of the sliding tube 2. The sliding tube 2 and the fins 12 are welded together. The surface of the sliding tube 2 is rounded. The surface of the fins 12 is provided with recesses 13. The fins are arranged in a matrix, with each concave point 13 having the same depth. The surface of the fin 12 is provided with an annular groove 3, and the annular groove 3 is welded to the fin 12. The surface of the annular groove 3 is rounded. One side of the heat exchange tube 1 is provided with a liquid outlet pipe 10, and the liquid outlet pipe 10 is positioned and connected to the heat exchange tube 1. One side of the liquid outlet pipe 10 is provided with a connecting flange 11, and the connecting flange 11 is welded to the liquid outlet pipe 10. One side of the heat exchange tube 1 is provided with a positioning plate 7, and the surface of the positioning plate 7 is provided with a connecting hole 8. One side of the heat exchange tube 1 is provided with a liquid inlet pipe 9. An annular groove 3 is installed around the fin 12, which firmly fixes the fin 12 in a specific position. This prevents the fin 12 from shifting due to impact forces or vibrations generated by fluid flow during heat exchanger operation, ensuring that the fin 12 is always in the optimal heat exchange position and maintaining a stable heat exchange effect. Simultaneously, the connection between the groove and the fin 12 adds an extra support structure, allowing the fin 12 to better distribute forces when subjected to pressure and stress, reducing the possibility of deformation or damage. This improves the overall strength and reliability of the heat exchanger structure. The annular groove 3 also guides and turbulents the fluid flowing through the fin 12. The flow action ensures a more uniform distribution of fluid around the fins 12, increasing the contact area and contact time between the fluid and the fins 12, enhancing the convective heat transfer process, and improving heat transfer efficiency. A first positioning ring 5 and a second positioning ring 6 are respectively provided on both sides of the sliding tube 2. Positioning bolts 4 are respectively provided on the surfaces of the first positioning ring 5 and the second positioning ring 6, achieving a matching positioning bolt 4. This prevents axial rotation or circumferential displacement of the sliding tube 2 during installation, ensuring that the direction of the sliding tube 2 is strictly fixed according to design requirements. This helps ensure the correct flow direction and path of the fluid within the tube, optimizing the heat transfer process. Meanwhile, the operating conditions of the heat exchanger, such as the temperature, flow rate, and velocity of the hot and cold fluids, are constantly changing. Adjustable spacing allows the heat exchanger to optimize the flow state and heat transfer effect between the fins 12 by changing the fin spacing according to specific operating conditions. For example, in power plants, the spacing of fins 12 is adjusted according to the ambient temperature and power generation load in different seasons to ensure that the heat exchanger in the condenser always maintains high heat exchange performance. The surface of fins 12 is provided with concave points 13, which increases the contact area between fins 12 and fluid.According to the principles of heat transfer, increasing the heat exchange area helps improve the efficiency of heat transfer, enabling the heat exchanger to achieve more efficient heat exchange within the same volume and space. When the fluid flows through the surface of the fins 12 with concave points 13, the concave points 13 disrupt the fluid's boundary layer, causing the fluid to generate more eddies and disturbances. This disturbance can accelerate heat transfer within the fluid, reduce thermal resistance, increase the convective heat transfer coefficient, and thus enhance the overall heat transfer performance of the heat exchanger. Specific Implementation Example 2:

[0028] Reference Figure 1-4 A magnetic block is used on one side of the sliding tube 2. This allows the magnetic block to be quickly and accurately attached to a specific position using magnetic force, making the installation of the sliding tube 2 more convenient. It enables quick and accurate fixing of the sliding tube 2 in the required position, reducing alignment and fixing time during installation and improving installation efficiency. When the heat exchanger needs inspection or maintenance, the magnetic block connection method facilitates the disassembly of the sliding tube 2. No complicated tools or cumbersome disassembly steps are required; the sliding tube 2 can be removed simply by overcoming the magnetic force, facilitating the inspection, repair, or replacement of components inside the heat exchanger.

[0029] In summary:

[0030] 1. By installing an annular groove 3 around the fin 12, the annular groove 3 can firmly fix the fin 12 in a specific position, preventing the fin 12 from shifting due to the impact force or vibration generated by the fluid flow during the operation of the heat exchanger. This ensures that the fin 12 is always in the optimal heat exchange position and maintains a stable heat exchange effect. At the same time, the connection between the groove and the fin 12 is equivalent to adding an extra support structure to the fin 12, which can better distribute the force when the fin 12 is subjected to pressure and stress, reducing the possibility of deformation or damage to the fin 12, thereby improving the strength and reliability of the overall structure of the heat exchanger. The annular groove 3 can also guide and turbulent the fluid flowing through the fin 12, making the fluid more evenly distributed around the fin 12, increasing the contact area and contact time between the fluid and the fin 12, enhancing the convective heat transfer process, and improving the heat transfer efficiency.

[0031] 2. A first positioning ring 5 and a second positioning ring 6 are respectively provided on both sides of the sliding tube 2. Positioning bolts 4 are respectively provided on the surface of the first positioning ring 5 and the second positioning ring 6. This ensures proper positioning and prevents axial rotation or circumferential displacement of the sliding tube 2 during installation, ensuring that the direction of the sliding tube 2 is strictly fixed according to design requirements. This helps ensure the correct flow direction and path of the fluid within the tube, optimizing the heat exchange process. Meanwhile, the operating conditions of the heat exchanger, such as the temperature, flow rate, and velocity of the hot and cold fluids, are constantly changing. Adjustable spacing allows the heat exchanger to optimize the flow state and heat exchange effect between the fins 12 by changing the fin spacing according to specific operating conditions. For example, in power plants, the fin spacing can be adjusted according to the ambient temperature and power generation load in different seasons to ensure that the heat exchanger in the condenser always maintains high-efficiency heat exchange performance.

[0032] 3. By incorporating recesses 13 on the surface of the fins 12, the contact area between the fins 12 and the fluid is increased. According to the principles of heat transfer, increasing the heat exchange area helps improve heat transfer efficiency, enabling the heat exchanger to achieve more efficient heat exchange within the same volume and space. When the fluid flows through the surface of the fins 12 with recesses 13, the recesses 13 disrupt the fluid boundary layer, generating more eddies and disturbances. This disturbance accelerates heat transfer within the fluid, reduces thermal resistance, increases the convective heat transfer coefficient, and thus enhances the overall heat transfer performance of the heat exchanger.
