Description

Technical Field

[0001] This application relates to the technical field of heat exchangers, and in particular to a self-supporting finned and vibration-damping finned heat exchanger. Background Technology

[0002] A finned heat exchanger is a heat exchange device used for heat exchange between gases and liquids. It improves heat transfer efficiency by adding fins to the surface of the heat exchange tubes. The working principle of a finned heat exchanger is as follows: when a cold fluid passes through the fins on the outside of the finned tube, it exchanges heat with the hot fluid inside the tube between the fins. The heat of the hot fluid is transferred to the cold fluid, causing it to heat up. The presence of fins increases the contact area between the heat exchange tube and the hot fluid outside the tube, thus improving the heat exchange effect.

[0003] In the existing technology, fins need to rely on stiffeners, support plates and other supports during assembly, which leads to structural redundancy and high assembly difficulty; and the spacing between fins is difficult to keep consistent, affecting the stability of heat exchange efficiency; in addition, fluid-induced vibration can cause fatigue damage to fins and heat exchange tubes when the heat exchanger is in use. Utility Model Content

[0004] This application proposes a self-supporting finned heat exchanger and a vibration-damping finned heat exchanger, which simplifies fin assembly, achieves self-support, ensures that the spacing between adjacent fins is the same, and provides vibration-damping functionality.

[0005] First aspect: This application provides a self-supporting fin, which adopts the following technical solution: A self-supporting fin includes a fin body, two support bars are provided on one side of the fin body, and a connecting groove for positioning is provided on the fin body. Two connecting grooves are provided corresponding to the two support bars. The two support bars extend into the two connecting grooves of adjacent fin bodies respectively. The support bars abut against the groove wall of the connecting groove to limit the distance between two adjacent fin bodies.

[0006] By adopting the above technical solution, when installing the fin body, two support bars are set on one side of the fin body. The support bars abut against the wall of the connecting groove of the adjacent fin body, so that the adjacent fin bodies form a self-supporting structure. No additional reinforcing ribs or support plates are required, which simplifies the assembly process. The setting of the connecting groove provides the support bars of the adjacent fin bodies with precise installation and fitting space, reducing the alignment difficulty during assembly and improving assembly efficiency.

[0007] Preferably, the fin body has a mounting hole in the middle to facilitate the installation and positioning of the fin body, and a mounting ring is provided on one side of the fin body. The mounting ring is coaxial with the mounting hole and has the same diameter.

[0008] By adopting the above technical solution, the mounting ring and the mounting hole are coaxial and have the same diameter. When used with the heating tube, the contact area between the fin body and the mounting component can be increased, the shaking of the fin body after installation can be reduced, and the structural stability of the fin body after assembly can be improved.

[0009] Preferably, the support bar is trapezoidal, and the long side of the support bar is fixed to the fin body; the support bar is inclined relative to the fin body.

[0010] By adopting the above technical solution, when the support bar is inserted into the connecting groove of the adjacent fin body for assembly, since the support bar is trapezoidal, the support bar moves a certain distance relative to the side wall of the connecting groove and then abuts against the side wall of the connecting groove. After that, the support bar no longer moves, so as to limit the distance between the two adjacent fin bodies and improve the stability of heat exchange efficiency.

[0011] Preferably, the fin body is figure-eight shaped, the mounting hole is located at the center of the fin body, and the two support bars are arranged along the central axis of the length direction of the fin body, and the two support bars are symmetrically distributed with the center of the mounting hole as the center.

[0012] By adopting the above technical solution, the fin body is designed in a "figure-eight" shape, and the support bars are symmetrically distributed along the central axis, so that the fin body can achieve uniform support and stable connection in multiple directions, which enhances the vibration resistance and heat exchange uniformity of the overall structure.

[0013] The second aspect: This application provides a vibration-damping finned heat exchanger, which adopts the following technical solution: A vibration-damping finned heat exchanger employs any of the aforementioned self-supporting finned bodies, comprising a mounting plate and multiple heating tubes, wherein the multiple heating tubes are mounted in a rectangular array on the mounting plate; the heating tubes pass through mounting holes in the finned bodies and are engaged with mounting rings, and the finned bodies on the same heating tube abut against the connecting grooves of adjacent finned bodies through support strips to form a self-supporting structure.

[0014] By adopting the above technical solution, the self-supporting fins are combined with the heating tubes and mounting plates. The fin bodies on the same heating tube abut against each other through support bars to form a self-supporting structure, eliminating the need for additional support components, simplifying the overall structure of the heat exchanger, and reducing production and assembly costs. The heating tubes are installed in a rectangular array, which, together with the self-supporting positioning of the fin bodies, makes the heat exchange components of the entire heat exchanger neatly arranged, ensuring that the fluid flows uniformly within the heat exchanger and improving the overall heat exchange efficiency.

[0015] Preferably, the central axes of the figure-eight fin bodies on two adjacent heating tubes are arranged perpendicular to each other in the length direction, and the end protrusions of the figure-eight fin bodies abut against and cooperate with the middle recesses of the figure-eight fin bodies on the adjacent heating tubes.

[0016] By adopting the above technical solution, the central axes of the figure-eight fin bodies on adjacent heating tubes are arranged perpendicular to each other, so that the fin bodies form an interlocking structure, which enhances the mutual restraint and support between the fin bodies, further suppresses vibration transmission, and improves the vibration resistance of the heat exchanger.

[0017] Preferably, it also includes a positioning ring, which has two positioning grooves. The two positioning grooves are respectively engaged with two adjacent heating tubes to limit the center distance between the two adjacent heating tubes. The positioning ring and the support strip do not interfere with each other. There are multiple positioning rings, and the multiple positioning rings connect multiple heating tubes into a whole.

[0018] By adopting the above technical solution, the positioning ring engages with adjacent heating tubes through two positioning grooves, precisely limiting the center distance between two adjacent heating tubes. This prevents misalignment and support failure of the fin body due to heating tube spacing deviation, ensuring the stability of the fin body's self-supporting structure. It also ensures that the positioning ring and support strip do not interfere with each other, guaranteeing that while the positioning ring performs its fixing function, it does not affect the support strip's function of supporting the fin body and limiting spacing, ensuring that each component of the heat exchanger functions independently and works collaboratively. The positioning ring provides a precise spacing positioning reference for the rectangular array installation of heating tubes, reducing the alignment difficulty during heating tube assembly and ensuring a neat layout of the entire heat exchanger's heat exchange components, thus guaranteeing stable fin body assembly and heat exchange efficiency. Multiple positioning rings connect multiple heating tubes into a whole, further suppressing vibration transmission and improving the heat exchanger's vibration resistance.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. When installing the fin body, two support bars are set on one side of the fin body. The support bars abut against the wall of the connecting groove of the adjacent fin body, so that the adjacent fin bodies form a self-supporting structure. No additional reinforcing ribs or support plates are required, which simplifies the assembly process. The setting of the connecting groove provides precise installation and fitting space for the support bars of the adjacent fin bodies, reducing the alignment difficulty during assembly and improving assembly efficiency. 2. The self-supporting fin body is combined with the heating tube and mounting plate. The fin bodies on the same heating tube abut against each other through support bars to form a self-supporting structure, eliminating the need for additional support components, simplifying the overall structure of the heat exchanger and reducing production and assembly costs. The heating tubes are installed in a rectangular array, which, together with the self-supporting positioning of the fin body, makes the heat exchange components of the entire heat exchanger neatly arranged, ensuring a uniform flow path of the fluid in the heat exchanger and improving the overall heat exchange efficiency. 3. The positioning ring engages with adjacent heating tubes via two positioning slots, precisely limiting the center distance between two adjacent heating tubes. This prevents misalignment of the fin body and support failure due to heating tube spacing deviation, ensuring the stability of the fin body's self-supporting structure. It also ensures that the positioning ring and support strip do not interfere with each other, guaranteeing that while the positioning ring provides fixation, it does not affect the support strip's function of supporting the fin body and limiting spacing, ensuring that each component of the heat exchanger functions independently and collaboratively. The positioning ring provides a precise spacing positioning reference for the rectangular array installation of the heating tubes, reducing the alignment difficulty during heating tube assembly and ensuring a neat layout of the entire heat exchanger's heat exchange components, thus guaranteeing stable fin body assembly and heat exchange efficiency. Multiple positioning rings connect multiple heating tubes into a single unit, further suppressing vibration transmission and improving the heat exchanger's vibration resistance.

[0022] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail.

[0023] This application discloses a self-supporting fin.

[0024] refer to Figure 1 A self-supporting fin includes a fin body 1 and a support bar 2. The fin body 1 is figure-eight shaped, and the support bar 2 is located on one side of the fin body 1. The support bar 2 is integrally stamped with the fin body 1. There are two support bars 2, which are located on the central axis of the length direction of the fin body 1 and are symmetrically arranged with the center of the fin body 1 as the center. A connecting groove 3 is opened on the fin body 1, and the support bar 2 is used to abut against an adjacent fin body 1 to limit the distance between the two adjacent fin bodies 1.

[0025] The fin body 1 has a mounting hole 4 for easy installation and positioning. The mounting hole 4 is coaxial with the center of the fin body 1. One side of the fin body 1 is integrally stamped with a mounting ring 5 for easy installation and positioning. The mounting ring 5 is coaxial with the mounting hole 4 and has the same diameter. The mounting ring 5 and the support bar 2 are located on the same side of the product body, increasing the contact area between the fin body 1 and the mounting component, reducing the shaking of the fin body 1 after installation, and improving the structural stability of the fin body 1 after assembly.

[0026] The support bar 2 is trapezoidal. The long side of the support bar 2 is connected to the fin body 1, and the short side of the support bar 2 is away from the fin body 1. The support bar 2 is inclined relative to the fin body 1 at an angle close to 90°. When the support bar 2 is inserted into the connecting groove 3 of the adjacent fin body 1 for assembly, because the support bar 2 is trapezoidal, the support bar 2 moves a certain distance relative to the side wall of the connecting groove 3 and then abuts against the side wall of the connecting groove 3. After that, the support bar 2 no longer moves, so as to limit the distance between the two adjacent fin bodies 1 and improve the stability of heat exchange efficiency.

[0027] This application also discloses a vibration-damping finned heat exchanger.

[0028] refer to Figure 1 and Figure 2 A vibration-damping finned heat exchanger includes a mounting plate 7, a heating tube 8, and the aforementioned fins 6. The heating tube 8 is arranged perpendicular to the mounting plate 7, passes through the mounting plate 7, and is snapped into the mounting plate 7. The heating tube 8 passes through the mounting hole 4 of the fin body 1 and is snapped into the mounting ring 5. The fin bodies 1 on the heating tube 8 abut against the connecting groove 3 of the adjacent fin bodies 1 through the support strip 2 to form a self-supporting structure, and the spacing between adjacent fin bodies 1 is the same.

[0029] refer to Figure 2 and Figure 3 The mounting plate 7 is a rectangular plate, and multiple heating tubes 8 are installed on the mounting plate 7 in a rectangular array. The central axes of the figure-eight fin bodies 1 on two adjacent heating tubes 8 are perpendicular to each other. The protrusions at the ends of the figure-eight fin bodies 1 abut against the recesses in the middle of the figure-eight fin bodies 1 on the adjacent heating tubes 8, so that the fin bodies 1 between adjacent heating tubes 8 support each other and form an interlocking structure, which enhances the mutual restraint and support between the fin bodies 1, further suppresses vibration transmission, and improves the vibration resistance of the heat exchanger.

[0030] refer to Figure 4 and Figure 5 It also includes a positioning ring 9, which is a rectangular plate with two positioning grooves 10. The size and outline of the positioning grooves 10 are adapted to the heating tubes 8. The two positioning grooves 10 are respectively engaged with two adjacent heating tubes 8 to limit the center distance between the two adjacent heating tubes 8.

[0031] The positioning ring 9 is engaged with the adjacent heating tube 8 through two positioning grooves 10, which precisely limits the center distance between the two adjacent heating tubes 8, preventing misalignment and support failure of the fin body 1 due to the offset of the spacing between the heating tubes 8, and ensuring the stability of the self-supporting structure of the fin body 1.

[0032] refer to Figure 4 and Figure 5 The positioning groove 10 is an arc-shaped groove on one side of the positioning ring 9. The diameter of the positioning groove 10 is the same as the diameter of the heating tube 8, and the circumference of the positioning groove 10 is slightly less than half of the circumference of the heating tube 8. This is to ensure that the positioning ring 9 will not interfere with the support bar 2 when it is engaged with the heating tube 8. There are multiple positioning rings 9. Multiple positioning rings 9 connect multiple heating tubes 8 into a whole, further suppressing vibration transmission and improving the vibration resistance of the heat exchanger.

[0033] The implementation principle of this application embodiment is as follows: After multiple heating tubes 8 are arranged in a rectangular array on the mounting plate 7, the heating tubes 8 are connected in pairs to form a whole using positioning rings 9; the fin body 1 is sleeved and installed on the heating tube 8, and abutted by the support strip 2 and the connecting groove 3, so that the adjacent fin body 1 forms a self-supporting structure, without the need for additional reinforcing ribs or support plates, simplifying the assembly process; at the same time, the fin body 1 of adjacent heating tubes 8 is arranged perpendicular to each other, so that the fin body 1 supports each other and forms an interlocking structure, which enhances the mutual restraint and support between the fin body 1, further suppresses vibration transmission, and improves the vibration resistance of the heat exchanger.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
