There are four spoilers 9 in the middle, two bellows racks 7, five baffles 8 and four spoilers 9 on the surface of which slide grooves 10 are provided. A block 13 is provided on the top of the moving rod 11. The outside of the moving rod 11 is surrounded by a heat exchange tube 6. The upper head 2 and the lower head 3 are flange-connected to the heat exchanger body 1. The heat exchanger body is sealed by the upper head and the lower head. The manhole 4 is integrally formed with the lower head 3. The user can enter the interior of the heat exchanger body through the manhole for maintenance or adjustment. The two sliders 5 are evenly set at both ends of the heat exchanger body 1, and the sliders 5 are connected to the heat exchanger body. 1 is integrally formed and used for guiding the movement of the baffle 8 and the spoiler 9. The five baffles 8 are evenly spaced and cross-set between the two bellows racks 7. The water flow inside the heat exchanger body is deflected by the baffles, thereby extending the flow time of the water flow. The four spoilers 9 are all set inside the heat exchanger body 1. The spoilers will further extend the flow time of the water flow, thereby improving the heat exchange efficiency. The four spoilers 9 are evenly set between every two bellows racks 7. The slide grooves 10 on the surfaces of the two bellows racks 7, the five baffles 8 and the four spoilers 9 are evenly set on the bellows. The two sides of the bellows rack 7, baffle 8 and spoiler 9 are used to be installed on the slider inside the heat exchanger body. The slide grooves 10 of the bellows rack 7, baffle 8 and spoiler 9 are all installed on the slider 5 of the heat exchanger body 1. The moving rod 11 is set in the middle of the heat exchanger body 1, and the moving rod 11 and the heat exchange tube 6 both pass through the bellows rack 7, baffle 8 and spoiler 9. The damping block 14 is integrally formed with the moving rod 11. The damping block 14 is set at the end away from the lower head 3, and two slots 12 are set at the end away from the damping block 14. The card block 13 is installed in the card slot 12.

[0026] Five baffles 8 are cross-set at equal intervals between the two bellows racks 7, and a spoiler 9 is set in the middle of each baffle 8. The four spoilers 9 are cross-set at equal intervals. The direction in which the spoiler 9 is set is consistent with the direction in which the baffle 8 on the left is set, and it resists the adjacent baffle 8. The baffle 8 and the spoiler 9 are used to extend the time for water to flow inside the heat exchanger body 1. The moving rod 11 passes through the four spoilers 9, the five baffles 8 and the two bellows racks 7, and the four spoilers 9 are fixed to the moving rod 11 by fixing bolts, so that when the moving rod 11 is pulled, the spoiler 9 will be driven to move together. A damping block 14 is provided at one end of the moving rod 11 close to the upper head 2 to prevent the moving rod 11 from being excessively moved. The movable rod 11 is movable, and two slots 12 are provided at one end near the manhole 4 on the surface of the lower head 3, and a block 13 is installed in one of the slots 12 for fixing the movable rod 11. When the movable rod 11 is moved, the block 13 can be stuck in the corresponding slot 12 to complete the fixation of the movable rod 11. After the movable rod 11 is fixed, the heat exchange tube 6 is installed around the movable rod 1, and the heat exchange tube 6, the corrugated tube rack 7, the baffle 8 and the spoiler 9 are pushed into the heat exchanger body 1. During the pushing process, the slide grooves 10 on both sides of the corrugated tube rack 7, the baffle 8 and the spoiler 9 will slide along the slider 5 on the inner wall of the heat exchanger body 1. When the spoiler 9 moves alone, the spoiler 9 will also slide along the direction of the slider 5, and the slider 5 will be The movement of the corrugated tube frame 7, the baffle 8 and the spoiler 9 provides guidance and limiting functions. After the installation is completed, the lower head 2 and the upper head 3 are installed on the heat exchanger body 1 by fixing bolts to seal the heat exchanger body 1. When the heat exchanger body 1 is in normal use, the four spoilers 9 are all against the baffle 8 in the same installation direction as the spoiler 9, and are fixed on the card slot 12 with the card block 13. When it is necessary to increase the overall heat exchange efficiency before use, the manhole 4 on the surface of the lower head 3 can be opened before use, and the heat exchanger body can be entered through the manhole 4. The inside of the heat exchanger body 1 is pulled out from the card slot 12 on the side of the moving rod 11 close to the manhole 4, and the moving rod 11 is pulled so that the moving rod 11 is close to the damping block at one end of the upper head 2. 14 is pressed against the bellows rack 7 near the side of the upper head 2, so that the four spoilers 9 are moved from the state of being attached to the baffle 8 to the middle position of the two adjacent baffles 8. When the moving rod 11 is pulled, the slot 12 on the surface of the moving rod 11 away from the end of the manhole 4 is moved from the inside of the heat exchanger body 1 through the bellows rack 7 near the end of the manhole 4 to the position of the lower head 3. At this time, the block 13 is stuck in the moved slot 12, and the moving rod 11 can be fixed to the column. By adding a spoiler 9 in the middle of each baffle 8, the liquid flow is increased, thereby increasing the contact time between the liquid and the heat exchange tube 6. At this time, the liquid can be sent into the interior of the heat exchanger body 1 through the cold water inlet on the top surface of the upper head 2 and then into the interior of the heat exchange tube 6. At the same time,The water inlet on the top surface of the heat exchanger body 1 will enter the heat source and exchange heat with the cold water inside the heat exchange tube 6. During heat exchange, the baffle 8 and spoiler 9 increase the contact time between the heat source and the heat exchange tube 6, thereby improving the overall heat exchange efficiency of the heat exchanger body 1. The cold water after heat exchange will be discharged from the heat exchanger body 1 through the water outlet on the bottom surface of the upper head 2. A partition is also provided inside the upper head 2 to separate the water inlet area and the water outlet area. The heat source after heat exchange will be discharged from the heat exchanger body 1 through the water outlet on the bottom surface of the heat exchanger body 1. Specific embodiment two:

When the manhole 4 is opened, the operator can pull out the block 13 on the moving rod 11 from the slot 12 through the manhole 4, and pull or push the moving rod 11 through the pull ring 15, making it easier and more convenient to move the moving rod 11. When the pulling or pushing of the moving rod 11 is completed, the block 13 is inserted into the corresponding slot 12 on the moving rod 11 to complete the fixation of the moving rod 11.
