Abstract
Description
Technical Field
[0001] This utility model relates to the field of plate-fin heat exchanger technology, and in particular to a plate-fin heat exchanger with a protective structure. Background Technology
[0002] Plate-fin heat exchangers typically consist of baffles, fins, seals, and guide vanes. Fins, guide vanes, and seals are placed between adjacent baffles to form a sandwich layer, called a channel. These sandwich layers are stacked according to different fluid flow patterns and brazed together to form a plate bundle, which is the core of the plate-fin heat exchanger. Plate-fin heat exchangers are widely used in industries such as petroleum, chemical, and natural gas processing.
[0003] Existing plate-fin heat exchangers are prone to damage during handling due to the lack of protection at the fins. Not only are the fins easily bumped and damaged, but the sharp fins can also easily cut the handlers.
[0004] Therefore, it is necessary to provide a plate-fin heat exchanger with a protective structure to solve the above-mentioned technical problems. Utility Model Content
[0005] This invention provides a plate-fin heat exchanger with a protective structure, which solves the problems that the fins are easily damaged by impacts and that the sharp fins can easily scratch the handlers.
[0006] To solve the above-mentioned technical problems, the present invention provides a plate-fin heat exchanger with a protective structure, comprising: a heat exchanger body, wherein a plurality of sets of fins are uniformly installed on the outer wall of the heat exchanger body, and annular disks are installed on the outer walls of both the left and right ends of the heat exchanger body. A plurality of limiting grooves are uniformly opened on the side walls of the two sets of annular disks. A limiting block is inserted into the inner wall of each set of limiting grooves. A rectangular plate is installed on the outer wall of each set of limiting blocks. A rectangular block is installed on the outer wall of each set of rectangular plates. Two sets of partitions are installed on the side of each set of rectangular blocks near the fins. Each pair of partitions is in close contact with the outer walls of the left and right sides of each set of fins. Locking components are installed between the left and right sides of the heat exchanger body and the side walls of the annular disks, and the locking components are in contact with the side walls of the limiting blocks.
[0007] Preferably, the locking assembly includes a rotating shaft, two sets of rotating shafts are fixedly connected to the outer walls of the left and right ends of the heat exchanger body, and a number of connecting plates are rotatably connected to the outer walls of the rotating shafts. An annular ring is installed between the other ends of the connecting plates, and a number of limiting plates are evenly installed on the outer walls of the annular ring. The side walls of each limiting plate are in contact with the side walls of the annular disc.
[0008] Preferably, the outer wall of the rotating shaft is provided with an external thread, and a nut is connected to the external thread.
[0009] Preferably, the outer wall of the nut is uniformly provided with several sets of anti-slip textures.
[0010] Preferably, the partition includes a waterproof layer, a moisture-absorbing layer, a flame-retardant layer, and a core. The core is located at the innermost part of the partition, and a flame-retardant layer is provided on the outside of the core. A moisture-absorbing layer is provided on the outer wall of the flame-retardant layer, and a waterproof layer is provided on the outside of the moisture-absorbing layer.

[0012] Compared with related technologies, the plate-fin heat exchanger with protective structure provided by this utility model has the following beneficial effects:
[0013] This utility model provides a plate-fin heat exchanger with a protective structure. Before the heat exchanger body is transported, the locking component is controlled to move away from the entry end of the limiting groove. Then, several sets of rectangular plates with limiting blocks are sequentially inserted into the limiting groove. At the same time, two sets of partitions installed on the rectangular blocks on the rectangular plates cover the left and right sides of the fins. This not only protects the fins from damage by external pressure, but also prevents the sharp fins from scratching workers during transportation. When the partitions need to be removed, the above process can be reversed. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 ,in, Figure 1 A schematic diagram of a preferred embodiment of the plate-fin heat exchanger with a protective structure provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the rectangular block. Figure 3 for Figure 1 The diagram shows the structure of the finned structure. Figure 4 for Figure 1 The diagram shows the structural schematic of the partition structure. Figure 5 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 6 for Figure 2 The enlarged schematic diagram of section B is shown below; Figure 7 for Figure 3 The enlarged schematic diagram of section C is shown. The plate-fin heat exchanger with protective structure includes: a heat exchanger body 1, on which several sets of fins 5 are evenly installed on the outer wall; annular disks 6 are installed on the outer walls of both ends of the heat exchanger body 1; several sets of limiting grooves 9 are evenly opened on the side walls of the two sets of annular disks 6, the limiting grooves 9 penetrating the outer wall of the annular disks 6; a limiting block 8 is inserted into the inner wall of each set of limiting grooves 9; a rectangular plate 7 is installed on the outer wall of each set of limiting blocks 8; a rectangular block 2 is installed on the outer wall of each set of rectangular plates 7; two sets of partitions 4 are installed on the side of each set of rectangular blocks 2 near the fins 5; the partitions 4 are in close contact with the outer walls of the left and right sides of each set of fins 5; locking components 3 are installed between the left and right sides of the heat exchanger body 1 and the side walls of the annular disks 6, and the locking components 3 are in contact with the side walls of the limiting blocks 8.
[0024] The locking assembly 3 includes a rotating shaft 31. Two sets of rotating shafts 31 are fixedly connected to the outer walls of the left and right ends of the heat exchanger body 1, respectively. Several sets of connecting plates 32 are rotatably connected to the outer walls of the rotating shafts 31. An annular ring 34 is installed between the other ends of the several sets of connecting plates 32. Several sets of limiting plates 33 are evenly installed on the outer walls of the annular ring 34. The side walls of each set of limiting plates 33 are in contact with the side walls of the annular disk 6. The side walls of the limiting plates 33 are in contact with the outer walls of the limiting blocks 8. Rotating the connecting plates 32 causes the annular disk 6 to move the limiting plates 33 away from the entry end of the limiting groove 9, thereby facilitating the removal of the limiting blocks 8 inside the limiting groove 9.
[0025] The outer wall of the rotating shaft 31 is provided with an external thread 35, and a nut 36 is connected to the external thread of the external thread 35. When it is necessary to fix the connecting plate 32, tighten the nut 36; otherwise, loosen the nut 36.
[0026] The outer wall of the nut 36 is evenly provided with several sets of anti-slip textures 10. The anti-slip textures 10 improve the friction on the outside of the nut 36, making it easier for the user to rotate.
[0027] The partition 4 includes a waterproof layer 41, a moisture-absorbing layer 42, a flame-retardant layer 43, and a core 44. The core 44 is located at the innermost part of the partition 4, and a flame-retardant layer 43 is provided on the outside of the core 44. A moisture-absorbing layer 42 is provided on the outer wall of the flame-retardant layer 43, and a waterproof layer 41 is provided on the outside of the moisture-absorbing layer 42. The waterproof layer 41 and the moisture-absorbing layer 42 are both used to isolate moisture, and the flame-retardant layer 43 ensures that the core 44 is not affected by fire.
[0028] Both the limiting groove 9 and the limiting block 8 are T-shaped. This shape allows the limiting block 8 to enter and exit from only one end, making it convenient to limit its movement.
[0029] The working principle of the plate-fin heat exchanger with protective structure provided by this utility model is as follows: Before the heat exchanger body 1 is transported, the locking component 3 is controlled to move away from the entry end of the limiting groove 9. Then, several sets of rectangular plates 7 with limiting blocks 8 installed are sequentially inserted into the limiting groove 9. At the same time, the two sets of partitions 4 installed on the rectangular blocks 2 on the rectangular plates 7 respectively wrap around the left and right sides of the fins 5. When it is necessary to remove the partitions 5, the above process can be reversed.
[0030] Compared with related technologies, the plate-fin heat exchanger with protective structure provided by this utility model has the following beneficial effects:
[0031] Before the heat exchanger body 1 is moved, the locking assembly 3 is controlled to move away from the entry end of the limiting groove 9. Then, several sets of rectangular plates 7 with limiting blocks 8 installed are inserted into the limiting groove 9 in sequence. At the same time, the two sets of baffles 4 installed on the rectangular blocks 2 on the rectangular plates 7 respectively wrap around the left and right sides of the fins 5. This not only protects the fins 5 from damage by external pressure, but also prevents the sharp fins 5 from scratching workers during the handling process. When it is necessary to remove the baffles 5, the above process can be reversed.
[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
