Description

Technical Field

[0001] This invention relates to the field of heat exchanger technology, and in particular to a high-efficiency and energy-saving tubular heat exchanger. Background Technology

[0002] In many fields such as industrial production and mechanical equipment operation, tubular radiators are key equipment to ensure the stable operation of the system, and their performance directly affects the efficiency and lifespan of the overall system.

[0003] For example, a high-efficiency and energy-saving wastewater treatment heat exchanger disclosed on the Chinese Patent Network, with patent publication number "CN115752036B", mainly includes a tank body and multiple sets of water pipes inserted inside the tank body. Heat exchange mechanisms are fixedly and alternately at intervals on the inner wall of the tank body. The heat exchange mechanisms are flat, plate-like bodies that can deflect the liquid flowing into the tank body. Multiple sets of connecting pipes are fixed and connected to multiple sets of water pipes. This device redesigns the baffles in the original shell-and-tube radiator, so that the baffles not only serve a deflecting function, but also allow the liquid to exchange heat simultaneously as it enters the baffles through the water pipes, thus improving the heat exchange efficiency of the shell-and-tube radiator. However, this device still cannot solve the problem of not being able to flexibly adjust the cooling efficiency when the system load changes, resulting in energy waste or poor cooling effect. To solve the above problems, this invention proposes a novel high-efficiency and energy-saving tubular heat exchanger. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency and energy-saving tubular heat exchanger.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency and energy-saving tubular heat exchanger includes a tube body, a throttling component, a heat dissipation component, and a cleaning component.

[0007] One end of the pipe is fixedly connected to a cooling pipe inlet, and the other end is fixedly connected to a cooling pipe outlet. The axial outer wall of the pipe has two fluid inlets and two fluid outlets.

[0008] The throttling component is used to control the outflow and inflow of water. The throttling component consists of two reciprocating parts, two resetting parts, and a partition plate. The reciprocating parts can move laterally back and forth. When the reciprocating parts move laterally back and forth, they drive the heat dissipation component and the cleaning component to work. The resetting parts can retract and expand. The resetting parts are used to drive the reciprocating parts to reset.

[0009] The heat dissipation component is used to assist the heat dissipation of the tube body. The heat dissipation component can reciprocate in a fan shape, thereby increasing the heat dissipation area of ​​the heat dissipation component and thus improving the heat dissipation efficiency.

[0010] The cleaning component is used to remove impurities that adhere to the inner wall of the pipe during fluid transportation;

[0011] The tube body is divided into two cavities by a partition plate. The two reciprocating parts are respectively arranged inside the two cavities. The reset part is arranged on one side of the reciprocating part. The tube body is provided with two sliding grooves that restrict the movement of the reciprocating part.

[0012] The partition plate has an upper one-way opening and a lower one-way opening. A water pipe is fixedly connected to the outer wall of the pipe body. The two ends of the water pipe are respectively connected to two cavities. The water pipe is located behind the upper one-way opening and the lower one-way opening.

[0013] The upper and lower unidirectional ports on the partition plate are designed with staggered distribution, with the upper and lower unidirectional ports having opposite flow directions. This, combined with the connection position of the water pipe, ensures that the fluid flows unidirectionally within the pipe body along a preset path, avoiding fluid backflow interference between different cavities.

[0014] Preferably, the upper end of the reciprocating section is provided with an impact structure for triggering the heat dissipation module, and the maximum stroke of the two guide structures opened in the tube body is different, so that the reciprocating sections in the two cavities are staggered to improve the drainage effect.

[0015] Preferably, the heat dissipation component consists of a vertical section, a rotating section, and a storage section. The vertical section can move up and down as the reciprocating section moves horizontally back and forth, and the rotating section makes a fan-shaped motion as the vertical section moves up and down back and forth.

[0016] Preferably, the cleaning mechanism cleans the inner wall of the tube as the reciprocating part moves back and forth. When the reciprocating part moves in the first direction, the cleaning mechanism moves from the left end to the right end of the tube; when the reciprocating part resets, the cleaning mechanism returns from the left end to the left end.

[0017] Preferably, a cooling pipe is provided inside the pipeline, with one end of the cooling pipe fixedly connected to the cooling pipe inlet and the other end fixedly connected to the cooling pipe outlet.

[0018] Preferably, the vertical section is disposed on the outer wall of the pipe, the receiving section is disposed on the outer wall of the pipe body, the receiving section is arc-shaped, and the rotating section is fitted with the receiving section.

[0019] The present invention has the following beneficial effects:

[0020] 1. The device automatically controls the connectivity of the inner cavity of the tube based on fluid pressure through the cooperation of the reciprocating and resetting parts of the throttling component. When the device does not operate at full load, it can achieve single-cavity cooling and precisely control the fluid flow; under full load, the two cavities operate synchronously to ensure cooling efficiency. The unidirectional port design on the partition plate ensures unidirectional fluid flow, avoids backflow interference, improves throttling stability and controllability, and effectively meets the cooling requirements under different operating conditions.

[0021] 2. The heat dissipation component consists of a vertical section, a rotating section, and a retractable section. It utilizes the kinetic energy of the fluid propelling the sliding plate to drive the heat dissipation fins in a fan-shaped reciprocating motion. During the motion, the heat dissipation fins gradually unfold, increasing the contact area with the air and accelerating the heat dissipation speed of the tube. When resetting, the fins retract into the retractable plate, reducing the space occupied and providing protection. This improves the heat dissipation effect while also considering the spatial layout of the device and the protection of the components.

[0022] 3. The cleaning mechanism is linked with the reciprocating section. As the sliding plate moves laterally back and forth within the pipe, the cleaning ring closely adheres to the inner wall of the pipe, reciprocating from its initial position to the bottom of the pipe and then returning to its original position, achieving comprehensive cleaning of the upper and lower parts of the inner wall of the pipe. The special design of the sliding plate edge also assists in cleaning, effectively removing dirt and impurities from the inner wall, preventing pipe blockage and corrosion, reducing maintenance costs, and significantly extending the service life of the device.

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Example 1:

[0031] Reference Figures 1-6 A high-efficiency and energy-saving tubular heat exchanger includes a tube body 2, a throttling component, a heat dissipation component, and a cleaning component.

[0032] One end of the pipe body 2 is fixedly connected to a cooling pipe inlet 1, and the other end is fixedly connected to a cooling pipe outlet 3. Two fluid inlets 4 and two fluid outlets 5 are provided on the axial outer wall of the pipe body 2.

[0033] The throttling component is used to control the outflow and inflow of water. The throttling component consists of two reciprocating parts, two resetting parts, and a partition plate 6. The reciprocating parts can move laterally back and forth. When the reciprocating parts move laterally back and forth, they drive the heat dissipation component and the cleaning component to work. The resetting parts can retract and expand. The resetting parts are used to drive the reciprocating parts to reset.

[0034] The heat dissipation component is used to assist the heat dissipation of the tube body 2. The heat dissipation component can reciprocate in a fan shape, thereby increasing the heat dissipation area of ​​the heat dissipation component and thus improving the heat dissipation efficiency.

[0035] The cleaning mechanism is located on the outer wall of the reciprocating part. The cleaning mechanism is used to clean the pipes and reciprocates as the reciprocating part moves back and forth.

[0036] The interior of the pipe body 2 is divided into two cavities by the partition plate 6. Two reciprocating parts are respectively located inside the two cavities. The reset part is located on one side of the reciprocating part. The pipe body 2 has a groove to restrict the movement of the reciprocating part. The partition plate 6 has an upper one-way port 20 and a lower one-way port 17. A water pipe 19 is fixedly connected to the outer wall of the pipe body 2. The two ends of the water pipe 19 are respectively connected to the two cavities. The water pipe 19 is located behind the upper one-way port 20 and the lower one-way port 17.

[0037] A cooling pipe 18 is installed inside the pipe body 2. One end of the cooling pipe is fixedly connected to the cooling pipe inlet 1, and the other end is fixedly connected to the cooling pipe outlet 3. The upper unidirectional port 20 and the lower unidirectional port 17 on the partition plate are designed to be staggered. The flow directions of the upper unidirectional port 20 and the lower unidirectional port 17 are opposite. With the connection position of the water pipe, the fluid is ensured to flow unidirectionally in the pipe body according to the preset path, avoiding fluid backflow interference between different cavities.

[0038] Reference Figure 3-6 The reciprocating part can be specifically manufactured, the slide plate 8, the impact block 9, and the reset part can be specifically manufactured, and the reset telescopic cylinder 7 is specifically manufactured. The cooling pipe 18 passes through and slides through the slide plate 8. The impact block 9 is fixedly connected to the upper end of the slide plate 8. The reset telescopic cylinder 7 is equipped with a reset spring 701. The telescopic end of the reset telescopic cylinder 7 is fixedly connected to the slide plate 8, and the cylinder body end of the reset telescopic cylinder 7 is fixedly connected to the cooling pipe inlet 1. It should be noted that one end of the water pipe 19 is connected to the front cavity at the maximum stroke of the slide plate 8 in the direction of movement, and the other end is connected to the rear cavity at the maximum stroke of the direction of movement to ensure unidirectional fluid flow. There are two sets of water pipes 19, which are symmetrically arranged. It should be noted that the two grooves opened in the pipe body 2 have different maximum strokes, so that the two cavities have better drainage effect. It should be noted that temperature sensors are set at the positions of the two fluid outlets 5. It should be noted that the two fluid inlets 4 work intermittently. This working mode can make the heat dissipation effect of the device better.

[0039] In this embodiment, the device operates as follows: when the device does not require full load and needs rapid cooling, the fluid to be cooled is introduced only through one fluid inlet 4. The cooling medium flows into the cooling pipe 18 through the cooling pipe inlet 1 and is discharged through the cooling pipe outlet 3. When the fluid enters the pipe body 2 from the fluid inlet 4, the impact force of the water flow pushes the slide plate 8 to move laterally within the groove of the pipe body 2. The slide plate 8 drives the impact block 9 to move synchronously. At the same time, the slide plate 8 moves and stretches the reset spring 701 inside the reset telescopic cylinder 7, causing the reset telescopic cylinder 7 to unfold.

[0040] When the slide plate 8 moves and passes the upper one-way port 20 on the partition plate 6 (if the fluid to be cooled enters through another lower fluid inlet, the corresponding slide plate 8 moves and passes the lower one-way port 17), the fluid in the pipe 2 flows into the lower cavity through the upper one-way port 20 (conversely, the fluid flows into the upper cavity through the lower one-way port 17). After being cooled by the cooling pipe 18, the fluid to be cooled is discharged from the fluid outlet 5. Due to the characteristics of the one-way port, the fluid can only flow in one direction, ensuring the stability and controllability of the throttling. When the water pressure decreases or stops, the reset spring 701 in the reset telescopic cylinder 7 releases its elastic potential energy, pushing the telescopic end of the reset telescopic cylinder 7 to extend, thereby driving the slide plate 8 to reset. During the reset process, the slide plate 8 drives the impact block 9 to return to its initial position, and the upper one-way port 20 and the lower one-way port 17 on the partition plate 6 close again, completing one working cycle. Waiting for the next flow of water into the cooling pipe inlet 1, the above workflow is restarted. When full load operation is required, the slide plates 8 in the two chambers slide simultaneously until they pass the upper one-way port 20 and the lower one-way port 17 and reach the back of the water pipe 19. The fluid that needs to be cooled flows into the chamber behind the slide plate through the water pipe 19 and is then discharged through the fluid outlet 5. Example 2:

[0041] Reference Figures 3-5 Compared to Embodiment 1, the heat dissipation component in this embodiment consists of a vertical section, a rotating section, and a storage section. The vertical section can move up and down as the reciprocating section moves horizontally back and forth. The rotating section moves in a fan shape as the vertical section moves up and down back and forth. The storage section is located on the outer wall of the tube body and is arc-shaped. The rotating section fits into the storage section.

[0042] Reference Figure 3-5 The vertical section can be specifically made into a slider 11, a transmission rod 12, and a collar 10; the rotating section can be specifically made into a connecting rod 13, a fixing plate 14, a rotating shaft 15, and a heat dissipation fin 16; the storage section can be specifically made into a storage plate 161. Specifically, the slider 11 passes through the sliding connecting tube 2, the transmission rod 12 passes through and is fixedly connected to the slider 11, the collar 10 is rotatably connected to the outer wall of the transmission rod 12, the fixing plate 14 is fixedly connected to the outer wall of the tube 2, the rotating shaft 15 is fixedly connected to the fixing plate 14, and the rotating shaft 15 passes through and is rotatably connected to the connecting rod 13. One end of the connecting rod 13 is fixedly connected to the collar 10, and the other end is fixedly connected to the heat dissipation fin 16. It should be specifically noted that the swing angle range of the heat dissipation fin 16 is 0° to 60°.

[0043] In this embodiment, the fluid to be cooled is introduced into the pipe body 2 through the fluid inlet 4. The fluid pushes the slide plate 8 to move laterally back and forth in the groove of the pipe body 2. When the slide plate 8 moves, it drives the impact block 9 to move synchronously. When the impact block 9 hits the slider 11, since the slider 11 passes through the sliding connection pipe body 2, the slider 9 is pushed up by the impact block 11, thereby driving the rotating rod 12 to be pushed up together.

[0044] When slider 11 moves upward, it drives transmission rod 12 to move upward synchronously. The collar 10, rotatably connected to the outer wall of transmission rod 12, moves up and down with transmission rod 12. The movement of collar 10 is transmitted through connecting rod 13. Because rotating shaft 15 passes through and rotatably connects to connecting rod 13, and rotating shaft 15 is fixedly connected to fixed plate 14 fixed to the outer wall of tube 2, the up and down movement of collar 10 causes connecting rod 13 to perform a fan-shaped motion around rotating shaft 15. The heat dissipation fins 16, fixedly connected to one end of connecting rod 13, gradually unfold as connecting rod 13 performs this fan-shaped motion, continuously increasing the contact area with air, thereby increasing the heat dissipation area and accelerating the heat dissipation speed of tube 2.

[0045] During the fan-shaped unfolding and retraction of the heat dissipation fins 16, they remain in contact with the storage plate 161. When the heat dissipation fins 16 unfold, they slide along the surface of the storage plate 161, ensuring the stability and guidance of the movement of the heat dissipation fins 16; when the slide plate 8 returns to its original position and the heat dissipation fins 16 retract, they again adhere to the storage plate 161 and are stored in the storage plate 161 on the outer wall of the tube body 2, reducing the space occupied and protecting the heat dissipation fins 16 from external damage.

[0046] When the fluid pressure decreases or stops, the slide plate 8 resets under the action of the reset spring 701 inside the reset telescopic cylinder 7. The reset of the slide plate 8 causes the impact block 9 to move away from the slider 11. At this time, the slider 11, which is no longer restricted, drives the transmission rod 12 and other components to reset. The collar 10, connecting rod 13 and heat dissipation fins 16 also return to their initial state. The heat dissipation fins 16 re-attach to the storage plate 161, completing one heat dissipation cycle, and waiting for the next movement of the slide plate 8 to start the heat dissipation process again. Example 3:

[0047] Reference Figures 1-6 Compared to Embodiment 1 and Embodiment 2, in this embodiment, the cleaning mechanism cleans the inner wall of the tube 2 by reciprocating the reciprocating part. When the reciprocating part moves in the first direction, the cleaning mechanism moves from the left end to the right end of the tube 2; when the reciprocating part resets, the cleaning mechanism returns from the left end to the left end.

[0048] The specific cleaning mechanism can be configured as a synchronizing rod 21 and a cleaning ring 22. One end of the synchronizing rod 21 is fixedly connected to the slide plate 8, and the other end is fixedly connected to the cleaning ring 22. There are two sets of cleaning rings 22, which are slidably connected in the two cavities respectively. It should be noted that the cleaning ring 22 is in close contact with the inner wall of the tube 2. It should also be noted that the length of the synchronizing rod is approximately half the length of the tube 2, and the maximum sliding distance of the slide plate 8 is approximately half the length of the tube 2. This allows the cleaning ring 22 to move the maximum distance just to the bottom of the tube 2. It should also be noted that the edge of the slide plate 8 adopts the same design as the edge of the cleaning ring 22, so that the slide plate 8 can also achieve the same cleaning effect as the cleaning ring.

[0049] In this embodiment, the slide plate 8 is in the initial position, and the synchronizing rod 21 and cleaning ring 22, which are fixedly connected to one end of the slide plate 8, are also in the initial position. The two sets of cleaning rings 22 are slidably connected to the two cavities of the tube body 2, and are tightly fitted to the inner wall of the tube body 2, waiting to perform the cleaning task.

[0050] The fluid requiring cooling is introduced into the pipe body 2 through the fluid inlet 4. The fluid pushes the slide plate 8 to move laterally back and forth within the groove of the pipe body 2. Since one end of the synchronizing rod 21 is fixedly connected to the slide plate 8 and the other end is fixedly connected to the cleaning ring 22, the movement of the slide plate 8 will drive the synchronizing rod 21 and the cleaning ring 22 to move synchronously. Because the length of the synchronizing rod 21 is approximately equal to half the length of the pipe body 2, the maximum sliding distance of the slide plate 8 is approximately half the length of the pipe body 2. During the movement of the slide plate 8, the cleaning ring 22 moves along the inner wall of the pipe body 2 from the initial position to the bottom of the pipe body 2 until it reaches the bottom of the pipe body 2, thus cleaning the lower half of the inner wall of the pipe body 2.

[0051] As the cleaning ring 22 moves, it closely adheres to the inner wall of the tube 2, cleaning away dirt and impurities adhering to the inner wall through friction. Simultaneously, the edge of the sliding plate 8 employs the same design as the edge of the cleaning ring 22. During the movement of the sliding plate 8, its edge also cleans the inner wall of the tube 2 it contacts, assisting the cleaning ring 22 in completing its cleaning work and ensuring a thorough cleaning of the inner wall of the tube 2.

[0052] When the fluid pressure decreases or stops, the slide plate 8 resets under the action of the reset spring 701 within the reset telescopic cylinder 7. During the reset process, the slide plate 8 drives the synchronizing rod 21 and the cleaning ring 22 to move in the opposite direction. The cleaning ring 22 moves from the bottom of the pipe body 2 back to its initial position, cleaning the upper half of the inner wall of the pipe body 2 again during this process, cleaning the areas that were not cleaned before. Finally, the slide plate 8, synchronizing rod 21, and cleaning ring 22 return to their initial positions, completing one complete cleaning cycle, and waiting for the next movement of the slide plate 8 to start the cleaning process again.

[0053] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
