Technical Field

[0002] In the field of industrial production and energy conversion, heat exchangers are key equipment for heat transfer, and their performance and efficiency directly affect the operation effect and energy consumption level of the entire system. In traditional heat exchanger design, smooth tubular structures, namely heat transfer tubes, are mostly used to transport cold fluids. Although heat exchange is performed to a certain extent, the heat exchange efficiency is limited; In addition, during long-term operation, impurities such as scale and stones are easily accumulated inside the heat transfer tubes. These dirt will not only reduce the heat transfer efficiency and increase energy consumption, but may also cause equipment failure and shorten the service life of the equipment. The common floating heat exchangers on the market need to be fully disassembled when cleaning the internal heat transfer tubes. After all the heat transfer tubes are disassembled, the inside of the heat transfer tubes are rinsed with a high-pressure water gun or a chemical cleaning agent.

[0014] Compared with the prior art, the present invention provides a floating heat exchanger using three-dimensional fin tubes, which has the following beneficial effects: 1. The mobile heat exchanger using three-dimensional finned tubes is provided with a cleaning structure and a knocking structure. When the mobile heat exchanger needs to clean the three-dimensional heat transfer tube and the three-dimensional fin body during long-term use, the operator adjusts the driving structure so that all the cleaning scrapers are in contact with the aligned three-dimensional heat transfer tubes, and the electromagnetic component releases the fixation of the cleaning scraper. When the cold fluid enters the corresponding head through the cold water inlet pipe, the cleaning scraper automatically enters the three-dimensional heat transfer tube under the action of pressure, thereby scraping and cleaning the scale and stones inside the three-dimensional heat transfer tube, and when the adjustment component moves inside the three-dimensional heat transfer tube, The movable rod and the knocking frame knock inside the three-dimensional heat transfer tube, thereby knocking the more stubborn scale and stones inside the three-dimensional heat transfer tube, making it easier for the cleaning scraper at the rear to clean them. When knocking the three-dimensional heat transfer tube, it provides additional physical impact force for the stubborn scale and stones inside the three-dimensional heat transfer tube that are difficult to remove by simple scraping, effectively promoting the loosening and falling off of these stubborn dirt. At the same time, the vibration waves generated by the knocking can also be transmitted to the three-dimensional fin body, which helps the small scale and stones attached to its outer wall to fall off naturally due to vibration, thereby achieving a comprehensive and in-depth cleaning effect on the entire heat exchange surface, and the operation is convenient to ensure work efficiency.
[0015] 2. The floating heat exchanger using three-dimensional finned tubes is provided with a fixed structure. After the cleaning scraper cleans the scale stones inside the three-dimensional heat transfer tube, the operator adjusts the external water pump and other transfer equipment to allow the cold fluid to enter the floating heat exchanger through the cold water outlet pipe. Under the action of the baffle, the cold fluid pushes the cleaning scraper to automatically reset to the inside of the mounting plate. After the electromagnetic component is energized and works, the cleaning scraper is limited and fixed to avoid falling off, thereby ensuring that the floating heat exchanger can work normally.
[0016] 3. The floating heat exchanger using three-dimensional finned tubes is provided with an elastic structure. When the cleaning scraper moves inside the three-dimensional heat transfer tube, if the roller encounters relatively stubborn scale and stones, the first spring and the ejector plate cooperate to make the roller automatically move close to the axis of the three-dimensional heat transfer tube, thereby avoiding obstruction to the movement of the roller and ensuring that the rear cleaning scraper can normally scrape and clean the scale and stones inside the three-dimensional heat transfer tube.
[0017] 4. The floating heat exchanger using three-dimensional fin tubes expands the heat dissipation area by setting a three-dimensional fin body and setting a pin-fin-shaped three-dimensional fin body on the surface of the three-dimensional heat transfer tube. The needle-shaped body has gaps, which is conducive to liquid flow and reduces resistance, thereby satisfying the requirement of reducing pressure loss. BRIEF DESCRIPTION OF THE DRAWINGS

By setting the elastic structure 6, when the cleaning scraper 401 moves inside the three-dimensional heat transfer tube 104, if the roller 703 encounters relatively stubborn scale and stones, the roller 703 can automatically move close to the axis of the three-dimensional heat transfer tube 104 under the cooperation of the first spring 601 and the ejector plate 602, thereby avoiding obstruction to the movement of the roller 703 and ensuring that the rear cleaning scraper 401 can normally scrape and clean the scale and stones inside the three-dimensional heat transfer tube 104.
[0026] In the present invention, the adjustment component 7 includes a first rotating shaft 701 and a second rotating shaft 702 which are rotatably connected to the inside of two installation cabinets 503. The outer wall of the first rotating shaft 701 is fixedly connected to a roller 703 and two driving wheels 704.

By knocking inside the three-dimensional heat transfer tube 104, the more stubborn scale and stones inside the three-dimensional heat transfer tube 104 are knocked, which is convenient for the cleaning scraper 401 at the rear to clean them. When knocking the three-dimensional heat transfer tube 104, additional physical impact force is provided for the stubborn scale and stones inside the three-dimensional heat transfer tube 104 that are difficult to remove by simple scraping, which effectively promotes the loosening and falling of these stubborn dirt. At the same time, the vibration wave generated by the knocking can also be transmitted to the three-dimensional fin body 105, which helps the small scale and stones attached to its outer wall to naturally fall off due to vibration, thereby achieving a comprehensive and in-depth cleaning effect on the entire heat exchange surface, which not only optimizes the heat transfer efficiency but also extends the service life of the equipment.

When knocking the three-dimensional heat transfer tube 104, additional physical impact force is provided for the stubborn scale and stones inside the three-dimensional heat transfer tube 104 that are difficult to remove by simple scraping, which effectively promotes the loosening and falling of these stubborn dirt. At the same time, the vibration wave generated by the knocking can also be transmitted to the three-dimensional fin body 105, which helps the small scale and stones attached to its outer wall to naturally fall off due to vibration, thereby achieving a comprehensive and in-depth cleaning effect on the entire heat exchange surface, which not only optimizes the heat transfer efficiency but also extends the service life of the equipment.
[0032] In the present invention, a plurality of counterweight blocks 9 are fixedly connected to the outside of the knocking frame 802, and the shape of the counterweight blocks 9 is set to be a truncated cone. By setting the counterweight blocks 9, the weight of the knocking frame 802 is increased, thereby improving the knocking of the knocking structure 8 on the inner wall of the three-dimensional heat transfer tube 104, thereby ensuring its cleaning effect on scale and stones inside the three-dimensional heat transfer tube 104.
[0033] In the present invention, the fixed structure 3 includes a plurality of baffles 301 and electromagnetic components 302 fixedly connected to the mounting plate 201. The baffle 301 is located on one side of the mounting plate 201 surface close to the electric push rod 202. After the electromagnetic component 302 is powered on and works, the cleaning scraper 401 is adsorbed and fixed. By setting the fixed structure 3, after the cleaning scraper 401 cleans the scale stones inside the three-dimensional heat transfer tube 104, the operator adjusts the external water pump and other transfer equipment to allow the cold fluid to enter the inside of the mobile heat exchanger through the cold water outlet pipe 107b. Under the action of the baffle 301, the cold fluid pushes the cleaning scraper 401 to automatically reset to the inside of the mounting plate 201. After the electromagnetic component 302 is powered on and works, the cleaning scraper 401 is limited and fixed, so as to avoid the cleaning scraper 401 from falling off, thereby ensuring that the mobile heat exchanger can work normally.
[0034] Working principle: The operator connects the external pipes to the cold water inlet pipe 107a, the cold water outlet pipe 107b, the hot water outlet pipe 108a and the hot water inlet pipe 108b respectively, so that the cold fluid enters the interior of the floating heat exchanger through the cold water inlet pipe 107a, then enters the interior of the multiple three-dimensional heat transfer pipes 104, and finally is discharged through the cold water outlet pipe 107b. The hot fluid enters the interior of the shell 101 through the hot water inlet pipe 108b. Under the action of all the baffles 106, the hot fluid circulates in the interior of the shell 101 in an S shape, and finally is discharged through the hot water outlet pipe 108a. When the cold and hot fluids flow inside the floating heat exchanger, heat exchange is performed, thereby performing heat exchange processing; When the mobile heat exchanger needs to clean the three-dimensional heat transfer tube 104 and the three-dimensional fin body 105 during long-term use, the operator adjusts the electric push rod 202. When the electric push rod 202 is extended, the mounting plate 201 is pushed to move closer to the shell 101. At this time, the mounting plate 201 is located on the side of the cold water inlet pipe 107a close to the shell 101, so that all the cleaning scrapers 401 are in contact with the aligned three-dimensional heat transfer tube 104. The electromagnetic component 302 releases the fixation of the cleaning scraper 401. When the cold fluid enters the corresponding head 102 through the cold water inlet pipe 107a, the cleaning scraper 401 automatically enters the three-dimensional heat transfer tube 104 under the action of pressure. The cold fluid pushes the cleaning scraper 401 to move inside the three-dimensional heat transfer tube 104, thereby scraping and cleaning the scale and stones inside the three-dimensional heat transfer tube 104. In addition, since the roller 703 is in contact with the inner wall of the shell 101, when the cleaning scraper 401 moves When the roller 703 is in motion, the second rotating shaft 702 is driven to rotate rapidly through the driving wheel 704, the driven wheel 705 and the belt 706. When the second rotating shaft 702 drives the driving block 707 to rotate, the protruding block on the surface of the adjusting block 708 pushes the adjusting block 708, so that the adjusting block 708 pulls the driving column 805, the connecting frame 804, the movable rod 801 and the knocking frame 802 through the pulling plate 709 to move close to the axis of the three-dimensional heat transfer tube 104. As the driving block 707 continues to rotate, when the adjusting block 708 is turned over, the knocking frame 802 and the counterweight block 9 quickly hit the inside of the three-dimensional heat transfer tube 104 under the elastic force of the second spring 803, so as to knock the relatively stubborn scale stones inside the three-dimensional heat transfer tube 104, making it easier for the cleaning scraper 401 at the rear to clean them. When knocking the three-dimensional heat transfer tube 104, it is also easier to make the scale stones attached to the outer wall of the three-dimensional fin body 105 fall off; When the cleaning scraper 401 moves inside the three-dimensional heat transfer tube 104, if the roller 703 encounters relatively stubborn scale and stone, the first spring 601 and the ejector plate 602 cooperate to make the roller 703 automatically move close to the axis of the three-dimensional heat transfer tube 104, thereby avoiding obstruction to the movement of the roller 703 and ensuring that the rear cleaning scraper 401 can normally scrape and clean the scale and stone inside the three-dimensional heat transfer tube 104. When the cleaning scraper 401 moves inside the three-dimensional heat transfer tube 104 to the end away from the mounting plate 201 and cleans the scale and stones inside the three-dimensional heat transfer tube 104, the operator adjusts the external water pump and other transfer equipment to allow the cold fluid to enter the floating heat exchanger through the cold water outlet pipe 107b, so that the cold fluid enters the three-dimensional heat transfer tube 104 in the reverse direction, so that the three-dimensional heat transfer tube 104 moves closer to the mounting plate 201. Under the action of the baffle 301, the cold fluid pushes the cleaning scraper 401 to automatically reset to the inside of the mounting plate 201. After the electromagnetic component 302 is energized and works, the cleaning scraper 401 is limited and fixed.
