The movable block is fixedly connected to the connecting plate. A fixing plate is fixedly connected to the connecting plate. The end of the pressurizing rod away from the first piston is fixedly connected to the outer wall of the fixing plate.

[0010] To facilitate the rotation of the lead screw, preferably, a driving motor is fixedly connected to the outer wall of the cylinder body. The lead screw is fixedly connected to the output end of the driving motor.

[0011] To facilitate the sealing of the connection position of the heat exchange tubes, preferably, the sealing connection mechanism includes a connection cylinder fixedly connected to the partition plate. A limiting groove is provided on the inner wall of the connection cylinder. The heat exchange tube penetrates through the cavity of the connection cylinder and extends to the outside of the cylinder body. A sealing ring is sleeved on the outer wall of the heat exchange tube, and the outer wall of the sealing ring fits with the limiting groove.

[0012] To facilitate the reverse agitation of the flow inside the cylinder body, preferably, the buffer agitation mechanism includes a spiral plate arranged between the baffles. A rotating shaft is rotatably connected to the baffle, and the spiral plate is fixedly connected to the outer wall of the rotating shaft.

[0013] To facilitate the rotation of the rotating shaft, further, a sealing cover is detachably connected to the outer wall of the cylinder body. A pressure increasing disc is arranged inside the sealing cover. The bottom of the pressure increasing disc is fixedly connected to the cylinder body. A flow through pipe is fixedly connected to the intercepting plate. The input end of the flow through pipe is communicated with the input channel, and the output end of the flow through pipe is fixedly connected to the pressure increasing disc.

[0014] To facilitate the [operation not clear in the original, assuming it's a certain operation on the hot fluid], preferably, an inlet pipe and an outlet pipe are fixedly connected to the outer wall of the cylinder body. The inlet pipe is communicated with the input channel, and the outlet pipe is communicated with the output channel.

[0015] A heat exchange method for a heat exchanger, the operation steps are as follows:

[0016] Step 1: Introduce the hot fluid and the cold fluid into the inlet pipe and the heat exchange tube respectively;

[0017] Step 2: The hot fluid flows inside the input channel, and the spiral plate rotates synchronously;

[0018] Step 3: The cold fluid flows inside the heat exchange tube, and at the same time the heat exchange tube reciprocates;

[0020] Compared with the prior art, the present invention provides a heat exchanger structure and a heat exchange method, which have the following beneficial effects:

[0021] 1. The heat exchanger structure slides the heat exchange tubes on the partition plate by using a sealed connection mechanism, and thus can seal the heat exchange tubes during the movement process. The sealed connection mechanism provides necessary sealing to prevent leakage of the heat exchange cavity and ensure safety.

[0022] 2. The heat exchanger structure makes the moving direction of the cleaning plate always opposite to that of the heat exchange tubes. This means that when the heat exchange tubes move forward, the cleaning mechanism will move backward, thereby continuously cleaning the heat exchange tubes. This reverse cleaning mechanism ensures that even during the movement of the heat exchange tubes, the cleaning mechanism can effectively apply sufficient cleaning pressure to avoid the accumulation of scale, and further ensures that the heat conduction performance of the heat exchange tubes is not affected by pollutants, thus improving the heat exchange efficiency of the heat exchange tubes in this device.

[0023] 3. The heat exchanger structure can cause the fluid in the input channel to fluctuate reciprocally by the reciprocating movement of the cleaning plate. On the one hand, it can make the fluid fluctuate reciprocally in the input channel, increase the kinetic energy of the flow, and help break the stable state of the fluid layer, thereby improving the heat transfer efficiency. On the other hand, the dynamic fluid fluctuation helps prevent the re - accumulation of deposits such as scale on the heat exchange tubes.

[0024] 4. The heat exchanger structure has the flow direction stirred by the spiral plate always opposite to the flow directions of the input channel and the output channel. This reverse stirring design can enhance the dynamic mixing effect of the fluid, help break the stable state of the fluid layer, reduce the dead - zone phenomenon. The reverse stirring can make the fluid more evenly distributed in the heat exchange cavity, increase the contact area with the heat exchange tubes, and thus enhance the heat exchange efficiency.

[0025] The parts not involved in this device are the same as or can be implemented by using the prior art. The present invention can drive the cleaning plate to reciprocally move along the outer wall of the heat exchange tubes to clean the outer wall of the heat exchange tubes, avoid the accumulation of scale, and further ensure that the heat conduction performance of the heat exchange tubes is not affected by pollutants. Moreover, the reciprocally moving cleaning plate also helps break the stable state of the fluid layer in the heat exchange cavity, thereby improving the heat transfer efficiency, and its dynamic fluid fluctuation prevents the re - accumulation of deposits such as scale on the heat exchange tubes.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0036] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0037] Embodiment:

[0038] Refer to Figures 1 - 8, a heat exchanger structure, including a cylinder body 1 made of stainless steel. An inlet pipe 31 and an outlet pipe 32 are fixedly connected to the outer wall of the cylinder body 1. The inlet pipe 31 is communicated with an input channel, and the outlet pipe 32 is communicated with an output channel for conveying a heat fluid. A partition plate 3 is also installed on the inner wall of the cylinder body 1. The partition plate 3 divides to form a storage cavity and a heat exchange cavity. A flow dividing plate 4 is also installed on the inner wall of the heat exchange cavity. The flow dividing plate 4 is horizontally arranged between the cylinder bodies 1, and at least two groups of baffles 5 are arranged on the flow dividing plate 4. A vertical plate is also arranged between the baffles 5 for dividing the flow cavity above the flow dividing plate 4 to form a curved flow state. An intercepting plate 6 is fixedly connected above the flow dividing plate 4. The intercepting plate 6 divides the cavity above the flow dividing plate 4 independently to form an input channel. Through holes are opened on the flow dividing plate 4, the baffles 5 and the intercepting plate 6. The cross-sectional diameter of the through hole is slightly larger than the cross-sectional diameter of the heat exchange tube 2, so that the heat exchange tube 2 can reciprocate on the through hole. It should be noted that the intercepting plate 6 divides the cavity below the flow dividing plate 4 independently to form an output channel, and the output channel and the input channel are communicated through a flow pipe 7. When the heat fluid moves from the input channel to the output channel, the heat fluid will first be conveyed through the flow pipe 7.

[0039] A slidable heat exchange tube 2 is also arranged on the cylinder body 1. The heat exchange tube 2 is U-shaped and horizontally arranged. One end of the heat exchange tube 2 is arranged in the input channel, and the other end of the heat exchange tube 2 is arranged in the output channel. The heat exchange tube 2 is slidably arranged on the partition plate 3 through a sealing connection mechanism, so as to seal the heat exchange tube 2 during the moving process. Necessary sealing is provided through the sealing connection mechanism to prevent leakage of the heat exchange cavity and ensure safety.

[0040] The above-mentioned sealing connection mechanism includes a connection cylinder 28 fixedly connected to the partition plate 3. A limiting groove 29 is opened on the inner wall of the connection cylinder 28. The heat exchange tube 2 penetrates through the cavity of the connection cylinder 28 and extends to the outside of the cylinder body 1. A sealing ring 30 is sleeved on the outer wall of the heat exchange tube 2, and the outer wall of the sealing ring 30 fits with the limiting groove 29.

[0041] The connecting cylinder 28 is fixedly connected to the partition plate 3. As a connecting component between the heat exchange tube 2 and the cylinder body 1, a limiting groove 29 is provided inside it. The sealing ring 30 is sleeved on the outer wall of the heat exchange tube 2 to play a sealing role. The sealing ring 30 is made of rubber. The outer wall of the sealing ring 30 fits with the limiting groove 29, effectively preventing the fluid in the heat exchange cavity from leaking, ensuring the tightness and safety of the device. And to improve the sealing effect, two groups of connecting cylinders 28 are symmetrically arranged. The heat exchange tube 2 passes through the cavity of the connecting cylinder 28 and extends to the outside of the cylinder body 1, enabling it to be connected to an external system or device. During the connection process, a sliding bearing can be provided between the connecting pipe on the heat exchange tube 2 for buffering, allowing the heat exchange tube 2 to move freely with the help of the buffering device while maintaining a stable connection.

[0042] To facilitate the real-time cleaning of the possible scale residues on the outer wall of the heat exchange tube 2, a cleaning mechanism is provided in the heat exchange cavity. The working end of the cleaning mechanism forms a circular ring pattern covering the circumferential surface of the heat exchange tube 2. The inner wall of the circular ring pattern forms a tip that abuts against the outer wall of the heat exchange tube 2. When the heat exchange tube 2 reciprocates along the axis of the cylinder body 1, the moving direction of the cleaning mechanism is always opposite to the moving direction of the heat exchange tube 2. This means that when the heat exchange tube 2 moves forward, the cleaning mechanism will move backward, thus continuously cleaning the heat exchange tube 2. This reverse cleaning mechanism ensures that even during the movement of the heat exchange tube 2, the cleaning mechanism can effectively apply sufficient cleaning pressure to avoid the accumulation of scale, and further ensure that the heat conduction performance of the heat exchange tube 2 is not affected by pollutants, thereby improving the heat exchange efficiency of the heat exchange tube 2 in this device.

[0043] Furthermore, the above-mentioned cleaning mechanism includes a movable rod 26 slidably connected in the heat exchange cavity. A cleaning plate 27 is fixedly connected to the movable rod 26. Through holes are provided on the cleaning plate 27, and pointed blocks are arranged on the inner walls of the through holes. The ends of the pointed blocks abut against the circumferential surface of the heat exchange tube 2. The pointed blocks are arranged on the inner walls of the through holes and abut against the circumferential surface of the heat exchange tube 2. This design ensures that the pointed blocks can fully contact the heat exchange tube 2 and effectively remove the attached scale and other deposits. And the material of the pointed blocks can be selected as wear-resistant and corrosion-resistant materials, such as high-strength stainless steel, to improve its service life and cleaning effect. And when the cleaning plate 27 moves, it can cause the fluid in the input channel to fluctuate reciprocally. On the one hand, it can make the fluid fluctuate reciprocally in the input channel, increasing the kinetic energy of the flow, which helps to break the stable state of the fluid layer, thereby improving the heat transfer efficiency. On the other hand, the dynamic fluid fluctuation helps to prevent the re-accumulation of deposits such as scale on the heat exchange tube 2. And the cleaning plate 27 can also adsorb the heat in the heat exchange cavity, increasing the retention time of the heat in the hot fluid in the heat exchange cavity and improving the heat exchange efficiency of the heat exchange tube 2.

[0044] In order to ensure that the moving direction of the cleaning mechanism is always opposite to that of the heat exchange tube 2, a pressure boosting cylinder 19 is arranged in the storage cavity. The bottom of the pressure boosting cylinder 19 is fixedly connected to the outer wall of the partition plate 3. A pressure boosting rod 20 is slidably connected to the pressure boosting cylinder 19. A first piston 21 is fixedly connected to the pressure boosting rod 20. The first piston 21 fits against the inner wall of the pressure boosting cylinder 19. A transmission cylinder 22 is fixedly connected to the outer wall of the partition plate 3. A transmission rod 23 is slidably connected to the transmission cylinder 22. One end of the transmission rod 23 is fixedly connected to a second piston 24. The second piston 24 fits against the inner wall of the transmission cylinder 22. The end of the movable rod 26 extends into the storage cavity and is fixedly connected to a transmission plate 25. The other end of the transmission rod 23 is fixedly connected to the transmission plate 25. The transmission cylinder 22 is communicated with the pressure boosting cylinder 19 through a connecting pipe. Hydraulic oil is filled in the pressure boosting cylinder 19 and the transmission cylinder 22. When the pressure boosting rod 20 drives the first piston 21 to move along the inner wall of the pressure boosting cylinder 19, the hydraulic oil in the pressure boosting cylinder 19 can be conveyed into the transmission cylinder 22, so that the transmission rod 23 drives the movable rod 26 to move through the transmission plate 25. When the first piston 21 of the pressure boosting rod 20 moves in the pressure boosting cylinder 19, the hydraulic oil will be compressed, and the hydraulic oil will be conveyed into the transmission cylinder 22 through the connecting pipe. The pressure of the hydraulic oil pushes the second piston 24 to move to one side, thereby driving the transmission rod 23 and driving the movable rod 26 to move through the transmission plate 25. The cleaning plate 27 can move accordingly to ensure that its moving direction is always opposite to that of the heat exchange tube 2. In order to improve the stability of the cleaning plate 27 during movement, two groups of movable rods 26 are arranged in this device.

[0045] In order to facilitate the synchronous movement of the pressure boosting rod 20 driven by the heat exchange tube 2 during its reciprocating movement, a lead screw 15 is rotatably connected to the partition plate 3. A driving motor 14 is fixedly connected to the outer wall of the cylinder body 1. The driving motor 14 is a high-torque motor. The lead screw 15 is fixedly connected to the output end of the driving motor 14. The driving motor 14 drives the lead screw 15 to rotate. A movable block 17 is threadedly connected to the lead screw 15. A connecting plate 16 is fixedly connected to the outer wall of the heat exchange tube 2. The movable block 17 is fixedly connected to the connecting plate 16. A fixing plate 18 is fixedly connected to the connecting plate 16. The end of the pressure boosting rod 20 away from the first piston 21 is fixedly connected to the outer wall of the fixing plate 18. When the driving motor 14 drives the lead screw 15 to rotate, the movable block 17 can drive the heat exchange tube 2 to reciprocate through the connecting plate 16.

[0046] In order to further improve the fluctuation effect of the fluid in the input channel and the output channel, a buffer stirring mechanism is arranged in the heat exchange cavity. The working end of the buffer stirring mechanism is arranged between two groups of baffles 5. The flow direction stirred by the buffer stirring mechanism is always opposite to the flow direction of the input channel and the output channel. This reverse stirring design can enhance the dynamic mixing effect of the fluid, help to break the stable state of the fluid layer, reduce the dead zone phenomenon. The reverse stirring can make the fluid more evenly distributed in the heat exchange cavity, increase the contact area with the heat exchange tubes 2, and thus enhance the heat exchange efficiency.

[0047] The above-mentioned buffer stirring mechanism includes a spiral plate 13 arranged between the baffles 5. A rotating shaft 11 is rotatably connected to the baffle 5. The spiral plate 13 is fixedly connected to the outer wall of the rotating shaft 11. When the rotating shaft 11 rotates, the rotation of the spiral plate 13 will generate a certain thrust, prompting the fluid in the heat exchange cavity to flow countercurrently and enhancing the fluctuation of the fluid.

[0048] In order to facilitate the rotation of the rotating shaft 11, a sealing cover 33 is detachably connected to the outer wall of the cylinder 1 by bolts. A sealed cavity is formed between the sealing cover 33 and the cylinder 1. A pressure increasing disc 8 is arranged in the sealed cavity. The bottom of the pressure increasing disc 8 is fixedly connected to the cylinder 1. A flow pipe 7 is fixedly connected to the intercepting plate 6. The input end of the flow pipe 7 is communicated with the input channel, and the output end of the flow pipe 7 is fixedly connected to the pressure increasing disc 8. The pressure increasing disc 8 is communicated with the output channel through a delivery pipe. A transmission shaft is rotatably connected to the cavity of the pressure increasing disc 8. A turbine blade 9 is fixedly connected to the transmission shaft. When the fluid in the input channel flows into the output channel, the fluid is transported into the pressure increasing disc 8 through the flow pipe 7. At this time, the turbine blade 9 will drive the transmission shaft to rotate. A main gear 10 is fixedly connected to the end of the transmission shaft extending outside the pressure increasing disc 8. An auxiliary gear 12 is arranged at the end of the rotating shaft 11 extending into the cavity of the sealing cover 33. The auxiliary gear 12 meshes with the main gear 10, thereby driving the rotating shaft 11 to rotate.

[0049] A heat exchange method for a heat exchanger, the operation steps are as follows:

[0050] Step 1: Introduce the hot fluid and the cold fluid into the liquid inlet pipe 31 and the heat exchange tubes 2 respectively;

[0051] Step 2: The hot fluid flows inside the input channel, and the spiral plate 13 rotates synchronously;

[0052] Step 3: The cold fluid flows inside the heat exchange tube 2, and at the same time the heat exchange tube 2 reciprocates;

[0053] Step 4: The end of the pointed block on the cleaning plate 27 abuts against the outer wall of the heat exchange tube 2. At the same time, the cleaning plate 27 reciprocates, and the moving direction of the cleaning plate 27 is opposite to the moving direction of the heat exchange tube 2.

[0054] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
