Description

Technical Field

[0001] The invention belongs to the technical field of heat exchangers, in particular to a finned heat exchanger which is easy to disassemble and assemble. Background Art

[0002] Finned heat exchanger is the most widely used heat exchange equipment in gas and liquid heat exchangers. It achieves the purpose of enhancing heat transfer by adding fins to ordinary base tubes. It is widely used in air conditioning, refrigeration, chemical industry and other fields. Its core components include fins and heat exchange tubes. Finned heat exchanger adopts mechanical winding, the contact surface between the heat dissipation fins and the heat dissipation tubes is large and tight, the heat transfer performance is good and stable, the air resistance is small, steam or hot water flows through the steel pipe, and the heat is transferred to the air passing through the fins through the fins tightly wound on the steel pipe, so as to achieve the effect of heating and cooling the air.

[0003] For example, the utility model with the publication number CN222393391U discloses a novel finned heat exchanger, which relates to the technical field of heat exchangers, including two transfer tubes and two groups of carrier plates, both ends of the transfer tubes are fixed with sealing plugs, the two transfer tubes are arranged in parallel, and the peripheral side of the transfer tube is fixedly connected with a liquid guide tube and a plurality of fixed tubes, the other end of the liquid guide tube is provided with a rotating connector, the plurality of fixed tubes are arranged linearly, and a plurality of heat exchange tubes arranged linearly are arranged between the two transfer tubes. The first fixing plate on the fixed tube is fixed with the second fixing plate on the heat exchange tube by a first bolt, so that the fixed tube is connected with the heat exchange tube, and the heat exchange medium can be transmitted. When a heat exchange tube is damaged, it can be disassembled and replaced separately, and the connecting plate on the fin is fitted with the heat exchange tube. With the help of the second bolt, the fins arranged on both sides of the heat exchange tube can be fixed on the heat exchange tube, so that the heat exchange tube and the fin are detachable. In this way, the heat exchange tube is more convenient when repairing or replacing.

[0004] When the above device is in use, high-temperature gas or moisture used for heat exchange directly enters the internal pipe of the heat exchanger, which is easy to cause residual dirt on the inner wall of the pipe, affecting the service life of the device. Moreover, when the device is used for a long time, a large amount of dust accumulates on the fins, which is easy to affect the heat dissipation. The internal heat exchange tubes need to be cleaned regularly. Most of the existing heat exchange tubes are arranged in multiple forms inside the shell, and are generally fixed and locked by bolts. Since the finned heat exchanger has a complex structure and thin fins, the fins and heat exchange tubes are easily damaged during the disassembly and assembly process, resulting in reduced efficiency or equipment scrapping. In addition, the disassembly and assembly operation is more troublesome and the disassembly and assembly efficiency is low. Therefore, a finned heat exchanger that is easy to disassemble and assemble is proposed to solve the problems raised by the background technology. Summary of the invention

[0017] The present invention facilitates the pushing of the clamping mechanism into the interior of the heat exchanger case by arranging the coordination of structures such as tooth plates and gears, thereby avoiding the inconvenience of manual labor in reaching deep into the heat exchanger case during replacement. By utilizing the translation assembly, when it is necessary to reach deep into the interior of the heat exchanger case for replacement and clamping, the gear can be driven to rotate by a control motor, thereby driving the tooth plate meshing with the gear to slide, so that the trapezoidal slider at the bottom slides along the trapezoidal slide groove, driving the fixed plate to slide on the connecting seat, thereby driving the adjustment of the position of the entire clamping mechanism, thereby facilitating reasonable and deep clamping.

[0018] The present invention facilitates the adjustment of the distance between the two clamping mechanisms by setting the coordination of structures such as the first connecting rod, the second connecting rod, the adjustment block and the driving component. The driving component is used to drive the distance between the two connecting seats to adjust the reasonable adjustment of the distance between the two clamping blocks. The screw rod is driven to rotate by an adjusting motor, and the adjustment block on its surface slides along the mounting frame, thereby driving the adjustment of the angle between the second connecting rod and the first connecting rod, and driving the adjustment of the height of the top connecting seat, thereby achieving the adjustment between the two connecting seats. During the adjustment process, the moving block slides on the guide block, and the sliding rod slides in the sleeve rod. BRIEF DESCRIPTION OF THE DRAWINGS

In order to clamp the heat exchange tubes 2 of different sizes, the electric cylinder 36 can be used to drive the push block 33 along the slideway 3. 5. Since both sides of the push block 33 are inclined surfaces, when the electric cylinder 36 drives the push block 33 to move to the side away from the fixing plate 37, it squeezes the second pulley 312 to make it slide along the moving groove 331, thereby driving the angle of the connection between the two clamping blocks 31 and the mounting plate 34 to change, driving the two first pulleys 311 on the top of the clamping block 31 to clamp the heat exchange tube 2, and cooperating with the lifting component 43, the clamping mechanisms 3 at the top and bottom clamp the heat exchange tube 2 at the same time, making the fixation more stable and avoiding accidental contact with the fin 21 during replacement to cause damage.

[0026] The above scheme is adopted: by utilizing the translation assembly 42, when it is necessary to go deeper into the interior of the heat exchanger box 1 for replacement and clamping, the gear 422 can be driven to rotate by utilizing the control motor 423, thereby driving the tooth plate 421 meshing with the gear 422 to slide, so that the trapezoidal slider 4211 at the bottom slides along the trapezoidal slide groove 413, driving the fixed plate 37 to slide on the connecting seat 41, thereby driving the adjustment of the position of the entire clamping mechanism 3, thereby facilitating the realization of reasonable and deep clamping.

[0028] The above scheme is adopted: in order to adapt to the replacement of heat exchange tubes 2 of different lengths and make the clamping more stable, the distance between the two connecting seats 41 can be adjusted by utilizing the driving component 436, thereby realizing the reasonable adjustment of the distance between the two clamping blocks 31, and the screw 4361 is driven to rotate by adjusting the motor 4363, so that the adjustment block 434 on its surface slides along the mounting frame 4362, thereby driving the adjustment of the angle between the second connecting rod 435 and the first connecting rod 433, and driving the adjustment of the height of the top connecting seat 41, thereby realizing the adjustment between the two connecting seats 41.

During the adjustment process, the moving block 432 slides on the guide block 412, and the sliding rod 44 slides in the sleeve rod 45.
