Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to an impact-resistant finned tube heat exchanger. Background Technology

[0002] Due to their compact structure and high heat exchange efficiency, finned tube heat exchangers are widely used in various industrial heat exchange scenarios. Their core structure typically includes a shell, tube sheet, heat exchange tubes, and fins. The heat exchange tubes are inserted through the tube sheet and cooperate with the fins to form a heat exchange unit.

[0003] However, in practical applications, heat exchangers face multiple impact risks: First, during transportation and on-site installation, the equipment is prone to instantaneous impacts due to bumps and hoisting collisions, which can cause loosening or micro-cracks at the connection between the heat exchange tubes and the tube sheet; Second, during operation, fluid pulsation and equipment vibration can cause periodic impacts between the heat exchange tubes and the shell and fins, which can easily lead to fin detachment, heat exchange tube deformation, or even tube sheet cracking under long-term effects, seriously affecting the service life and operational safety of the heat exchanger. Utility Model Content

[0004] The purpose of this invention is to solve the problem of insufficient impact resistance in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an impact-resistant finned pipe heat exchanger, comprising a shell, characterized in that the impact-resistant finned pipe heat exchanger further comprises: fins, multiple of which are evenly installed inside the shell and connected to the interior of the shell via connecting frames symmetrically connected to their backs; heat exchange pipes, which pass through the shell and are movably connected to the fins to form a heat exchange core; a buffer element, disposed between the heat exchange pipes and the fins, with its end face abutting against the outer surface of the heat exchange pipes; and a shock-absorbing element, installed on the back of the shell; wherein the connecting frames are threadedly connected to the interior of the shell.

[0006] The technical effects of adopting the above-mentioned further solution are as follows: the device uses the connecting frame threaded connection to make the fins securely fixed in the shell, the buffer abuts against the heat exchange pipe and the fins, which can reduce the impact damage between the two, and the shock absorber is installed on the back of the shell, which can weaken the external impact. Overall, the impact resistance of the equipment is greatly improved, the stability of the heat exchange core is ensured, and the service life is extended.

[0007] In a preferred embodiment, the buffer includes: a fixed through groove, having multiple such grooves, which are disposed through multiple fins; and a support sleeve, riveted to the fixed through groove and made of silicone rubber; wherein the heat exchange pipe sequentially passes through the fixed through groove and is stably connected to the fins, and the inner diameter of the support sleeve is interference-fitted with the outer diameter of the heat exchange pipe.

[0008] The technical effect of adopting the above-mentioned further solution is that the heat exchange pipe is connected to the fins through the groove, and the inner diameter of the support sleeve and the outer diameter of the pipe are interference fit. This can not only stabilize the pipe and the fins, but also absorb the impact of both with the elasticity of the silicone rubber, avoid damage to the components, and improve the impact resistance of the heat exchanger.

[0009] In a preferred embodiment, the buffer further includes: multiple reinforcing columns disposed through the multiple fins; wherein the two ends of the reinforcing columns are connected to the housing by threads.

[0010] The technical effect of adopting the above-mentioned further solution is that this structure can connect the dispersed fins into a stable whole, limit the displacement and deformation of the fins under impact, avoid the fins from shifting and affecting the heat exchange pipes, further improve the heat exchanger's impact resistance, and ensure the stability of the heat exchange core.

[0011] In a preferred embodiment, the shock absorber includes: a shock absorber back frame disposed on the back of the housing; multiple mounting blocks welded to the left and right sides of the housing; and a positioning bolt movably mounted between the mounting blocks and the shock absorber back frame, with a positioning nut connected to its end; wherein the mounting blocks and the shock absorber back frame are threadedly connected to the positioning bolt.

[0012] The technical effect of adopting the above-mentioned further solution is that this structure can stabilize the shell and the shock-absorbing back frame, allowing the shock-absorbing back frame to bear external impacts, reducing the transmission of impacts to the inside of the shell, protecting the heat exchange core, and improving the overall impact resistance of the heat exchanger.

[0013] In a preferred embodiment, the shock absorber further includes: a reset member, which is provided in multiple sets and is evenly installed between the housing and the shock absorber back frame; and a limiting slot, which is provided in multiple sets and is symmetrically opened on the back of the housing and the end face of the shock absorber back frame; wherein the reset member is engaged in the limiting slot.

[0014] The technical advantage of adopting the above-mentioned further solution is that multiple sets of reset components of the shock absorber are engaged in the limiting slots of the housing and the shock absorber back frame. The number of reset components can be selected as needed to adapt to different impact scenarios, and it is convenient for replacement and maintenance.

[0015] In a preferred embodiment, the shock absorber further includes: a reset component consisting of multiple shock absorber springs and a connecting block; wherein the connecting block is welded to the upper and lower ends of the multiple shock absorber springs.

[0016] The technical effects of adopting the above-mentioned further solutions are as follows: the connecting block can assist the reset component in being inserted into the limiting slot, and the shock-absorbing spring can absorb the impact energy between the shell and the shock-absorbing back frame through its extension and contraction deformation, thereby weakening the vibration transmission. Combined with the connecting block to stabilize the structure, the shock absorption effect is further improved, ensuring the stability of the internal components of the heat exchanger.

[0017] In a preferred embodiment, the buffer further includes: anti-slip pads, two sets of which are attached to the upper and lower sides inside the housing; wherein the other end of the anti-slip pads abuts against both ends of the plurality of fins.

[0018] The technical effect of adopting the above-mentioned further solution is that the two sets of anti-slip pads of the buffer are pasted on the upper and lower sides of the shell, and the other end abuts against the two ends of multiple fins, which can increase the friction with the fins, limit the axial sliding of the fins under impact, and avoid the fins from shifting and causing uneven stress on the heat exchange pipe.

[0019] In a preferred embodiment, the buffer further includes: a shock-absorbing pad disposed in the middle of the anti-slip pad; wherein the shock-absorbing pad and the anti-slip pad are connected by adhesive bonding.

[0020] The technical effect of adopting the above-mentioned further solution is that the shock-absorbing pad is pasted in the middle of the anti-slip pad, and the two form a combined structure. The shock-absorbing pad can absorb impact energy through its own deformation and buffer the collision between the fins and the shell.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] 1. This utility model employs a collaborative design of multiple buffer structures. On one hand, a silicone rubber support sleeve is installed at the connection between the fins and the heat exchange pipe. The interference fit between the sleeve and the heat exchange pipe ensures connection stability and absorbs radial impact between them through its own elastic deformation, avoiding direct rigid collision between the heat exchange pipe and the fins and reducing the risk of pipe wear or cracking of the fin fixing groove. On the other hand, the shock-absorbing pads and anti-slip pads on the upper and lower sides inside the shell not only buffer the axial impact between the fin assembly and the shell, but also increase friction through the anti-slip pads to prevent the fin assembly from sliding and shifting under impact. At the same time, the reinforcing column penetrates the fin assembly and is threadedly fixed to the shell, further improving the overall impact resistance rigidity of the fin assembly.

[0023] 2. This utility model's shock absorber, through its modular design, significantly improves the device's impact resistance and practicality. First, the shock absorber back frame is fixed to the housing mounting block via positioning bolts, providing stable external support for the housing and reducing overall housing sway. Second, the reset component, composed of a shock absorber spring and a connecting block, engages within a limiting slot. Users can flexibly increase or decrease the number of reset components and adjust the shock absorption intensity according to actual impact requirements, offering greater adaptability compared to existing fixed shock absorber structures. Furthermore, the snap-fit ​​installation method of the reset component facilitates later maintenance and replacement, avoiding the cumbersome repair issues associated with damaged existing shock absorber components. In addition, the shock absorber spring can efficiently absorb external impact energy through expansion and contraction, converting vibration into elastic potential energy, weakening the impact on the internal heat exchange core of the housing, and significantly improving the overall impact resistance and service life of the equipment.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1:

[0033] Please see Figures 1-5 This embodiment provides an impact-resistant through-plate heat exchanger with a buffer structure, the specific concept of which is as follows:

[0034] An impact-resistant finned tube heat exchanger includes a shell 1, and the impact-resistant finned tube heat exchanger also includes heat exchange tubes 2, fins 3, connecting frame 6 and buffer.

[0035] Among them, the impact buffering between heat exchange pipe 2 and fin 3, and between fin 3 and shell 1 can be achieved through the coordinated cooperation of multiple buffer components.

[0036] Inside the shell 1, multiple fins 3 are evenly arranged.

[0037] In addition, each fin 3 has a connecting frame 6 symmetrically installed on its back.

[0038] It should be noted that the end of the connecting frame 6 away from the fin 3 is fixed to the inner wall of the housing 1 by a threaded connection, thereby achieving stable installation of the fin 3 inside the housing 1.

[0039] The heat exchange pipe 2 penetrates the interior of the shell 1.

[0040] It should be noted that the heat exchange pipe 2 and each fin 3 are connected in a movable manner, together forming the heat exchange core.

[0041] Meanwhile, to achieve the buffering function, a buffer element is provided between the heat exchange pipe 2 and the fin 3, and the end face of the buffer element is in close contact with the outer surface of the heat exchange pipe 2.

[0042] As some examples, in this embodiment, the buffer includes: multiple fixed through slots 16, support sleeves 5, multiple reinforcing columns 4, two sets of shock-absorbing pads 14, and anti-slip pads 15.

[0043] The fixed through slot 16 is formed through each fin 3.

[0044] The support sleeve 5 is fixed inside the fixed through groove 16 by riveting.

[0045] It should be noted that the support sleeve 5 is made of silicone rubber, which has good elasticity.

[0046] In addition, the heat exchange pipe 2 passes through the fixed through slots 16 on all the fins 3 in sequence.

[0047] It should be noted that the inner diameter of the support sleeve 5 and the outer diameter of the heat exchange pipe 2 are interference fit, so that the heat exchange pipe 2 can maintain a stable connection with the fins 3. At the same time, the support sleeve 5 can absorb the impact between the heat exchange pipe 2 and the fins 3 through its own elastic deformation.

[0048] Among them, the reinforcing column 4 is installed through the space between multiple fins 3.

[0049] It should be noted that the two ends of the reinforcing column 4 are connected to the inner wall of the shell 1 by threads, which further enhances the overall stability of the fin 3 in the shell 1 and prevents the fin 3 from shifting under impact.

[0050] In addition, two sets of anti-slip pads 15 are respectively pasted on the upper and lower sides inside the housing 1, and the end of the anti-slip pad 15 away from the inner wall of the housing 1 abuts against the two ends of the multiple fins 3, which can increase the friction between the anti-slip pad 15 and the fins 3 and prevent the fins 3 from sliding on the surface of the anti-slip pad 15.

[0051] The shock-absorbing pad 14 is attached to the middle of the anti-slip pad 15, which can buffer the impact between the fin 3 and the shell 1.

[0052] In this embodiment, the support sleeve 5 can directly absorb the radial impact between the heat exchange pipe 2 and the fins 3, avoiding damage caused by direct collision between the two; the reinforcing column 4 improves the overall rigidity of the fin group 3 and reduces the deformation of the fins 3 caused by impact; the shock-absorbing pad 14 and the anti-slip pad 15 work together to buffer the axial impact between the fins 3 and the shell 1, while preventing the fins 3 from sliding, ensuring the stability of the heat exchange core structure, and effectively improving the heat exchanger's ability to resist impact during operation and installation.

[0053] Example 2:

[0054] Please see Figures 1-5 Based on Example 1, this example provides an impact-resistant through-plate tube heat exchanger with a shock-absorbing structure, the specific concept of which is as follows:

[0055] The impact-resistant through-plate heat exchanger also includes shock-absorbing components.

[0056] The shock absorption of the shell 1 by the shock absorber can reduce the impact of external impact on the shell 1 and the internal heat exchange core.

[0057] As examples, in this embodiment, the shock absorber includes: a shock absorber back frame 7, multiple mounting blocks 11, positioning bolts 12, positioning nuts 13, multiple sets of reset components, and multiple sets of limit slots 8.

[0058] The shock-absorbing back frame 7 is located on the back of the housing 1.

[0059] In addition, multiple mounting blocks 11 are welded to the left and right sides of the housing 1 respectively.

[0060] Meanwhile, the positioning bolt 12 passes through the mounting block 11 and the shock-absorbing back frame 7, and the positioning bolt 12 is threadedly connected to the mounting block 11 and the shock-absorbing back frame 7.

[0061] It should be noted that the end of the positioning bolt 12 is screwed into the positioning nut 13, thereby fixing the mounting block 11 to the shock-absorbing back frame 7 and realizing the connection between the housing 1 and the shock-absorbing back frame 7.

[0062] Multiple sets of limiting slots 8 are symmetrically opened on the back of the housing 1 and the end face of the shock-absorbing back frame 7 facing the housing 1, and the reset component is engaged and installed in the limiting slots 8.

[0063] In addition, the reset component consists of multiple damping springs 9 and connecting blocks 10.

[0064] The connecting block 10 is welded to the upper and lower ends of multiple shock-absorbing springs 9.

[0065] It should be noted that the resetting component is fixed between the housing 1 and the shock-absorbing back frame 7 by engaging the connecting block 10 with the limiting slot 8. Depending on the actual application scenario and the required shock absorption effect, different numbers of resetting components can be installed. The snap-fit ​​installation method of the resetting components facilitates subsequent replacement and maintenance.

[0066] In this embodiment, when the housing 1 is subjected to external impact or vibration, the shock-absorbing back frame 7 can act as an external support, reducing the direct shaking of the housing 1. The shock-absorbing spring 9 in the reset component can absorb the impact energy between the housing 1 and the shock-absorbing back frame 7 through its own expansion and contraction deformation, converting the vibration into the elastic potential energy of the spring, thereby weakening the impact on the heat exchange core inside the housing 1. The cooperation between the positioning bolt 12 and the positioning nut 13 ensures a stable connection between the housing 1 and the shock-absorbing back frame 7, while not affecting the shock-absorbing effect of the reset component. Through this shock-absorbing structure, the damage to the overall structure of the heat exchanger caused by external impact and vibration is significantly reduced, extending the service life of the equipment.

[0067] Working Principle: This equipment is an impact-resistant finned tube heat exchanger. In use, multiple fins 3 are first evenly arranged according to the designed spacing. A connecting bracket 6 is symmetrically installed on the back of each fin 3. Then, a reinforcing column 4 is inserted through all fins 3, and both ends of the reinforcing column 4 are fixed to the inner wall of the shell 1 via threads, completing the initial positioning of the fin group 3. Next, anti-slip pads 15 are attached to the upper and lower sides inside the shell 1, and a shock-absorbing pad 14 is attached to the middle of the anti-slip pads 15 to ensure precise contact between the anti-slip pads 15 and the ends of the fins 3. Then, a silicone rubber support sleeve 5 is riveted into the fixing slot 16 of each fin 3. The heat exchange pipe 2 is then sequentially inserted through the fixing slots 16 of all fins 3. The interference fit between the inner diameter of the support sleeve 5 and the outer diameter of the heat exchange pipe 2 achieves a stable connection between the heat exchange pipe 2 and the fins 3, forming the heat exchange core. Simultaneously, the connecting bracket 6 is threaded to the inner wall of the shell 1, completing the assembly of the components inside the shell 1.

[0068] Next, the shock absorbers are installed. The shock absorber back frame 7 is placed on the back of the housing 1. Mounting blocks 11 are welded to the left and right sides of the housing 1. Positioning bolts 12 are passed through the mounting blocks 11 and the shock absorber back frame 7, and after threaded connection, positioning nuts 13 are screwed onto the ends of the positioning bolts 12 to achieve initial fixation between the housing 1 and the shock absorber back frame 7. According to the actual shock absorption requirements, a corresponding number of reset components are selected. The reset components consist of multiple shock absorber springs 9 and connecting blocks 10 welded to their upper and lower ends. The reset components are engaged with the limiting slots 8 on the back of the housing 1 and the end face of the shock absorber back frame 7 through the connecting blocks 10, completing the overall installation of the shock absorbers.
