Description

Technical Field

[0001] This utility model relates to the field of heat exchangers, specifically to a heat exchanger baffle assembly structure and a heat exchanger. Background Technology

[0002] Heat exchangers with baffles have a certain gap between the baffles and the inner wall of the shell due to assembly requirements. However, under the impact of fluid, this gap can cause the tube bundle inside the heat exchanger to vibrate, and in severe cases, cause tube bundle damage.

[0003] Especially when the heat exchanger is used horizontally, the weight of the baffle is entirely borne by a portion of the heat exchange tubes. Furthermore, the baffle is subjected to the impact force of the fluid, generating torque and vibration, which is also borne by a portion of the heat exchange tubes. Under the combined effects of gravity, torque, and vibration, some of the heat exchange tubes cannot withstand the load and break. Utility Model Content

[0004] To address the aforementioned technical problems, this disclosure provides a heat exchanger baffle assembly structure and a heat exchanger.

[0005] In a first aspect, this disclosure provides a heat exchanger baffle assembly structure, including a baffle and a cylinder, wherein the outer edge of the baffle is provided with a guide groove that extends through the axial direction of the cylinder;

[0006] It also includes a transition component, which is arranged along the axial direction of the cylinder. The transition component includes a first mating surface and a third mating surface. The first mating surface is adapted to achieve a wedge-shaped fit between the transition component and the guide slot along the axial direction of the cylinder. The third mating surface is adapted to abut against the inner wall of the cylinder in the final state of the baffle assembly.

[0007] Optionally, the first mating surface is provided in multiple locations along the length direction of the transition component and respectively engages with multiple guide slots of the baffle plate in a wedge shape along the axial direction of the cylinder.

[0008] Optionally, the transition component further includes a second mating surface, which is adapted to achieve a wedge-shaped fit between the transition component and the guide groove along the axial direction of the cylinder, and the wedge-shaped orientation of the second mating surface is opposite to that of the first mating surface.

[0009] Optionally, the second mating surface is provided in multiple locations along the length direction of the transition component and respectively engages with multiple guide slots of the baffle plate in a wedge shape along the axial direction of the cylinder.

[0010] Optionally, the adjacent first mating surfaces and second mating surfaces form a wedge-shaped spacing H1. Within the wedge-shaped spacing H1 section, the interior angle β formed by the first mating surfaces and the second mating surfaces is set radially inward along the cylinder. Furthermore, in the final state of the baffle assembly, the intersection position of the first mating surfaces and the second mating surfaces within the wedge-shaped spacing H1 section is offset from the guide slot.

[0011] Optionally, adjacent baffles form a plate spacing H2; along the axial direction of the cylinder, the plate spacing H2 and the wedge spacing H1 are arranged in an overlapping and staggered manner.

[0012] Optionally, the angle between the first mating surface, the second mating surface and the third mating surface is α, where 3°≤α≤15°.

[0013] Optionally, the transition component is configured as a plate with a thickness of δ, where δ = 5-10 mm; the guide groove has a width of w, where w ≥ 1.1δ.

[0014] Optionally, the transition component is provided at least three times along the outer edge of the baffle.

[0015] Secondly, this disclosure provides a heat exchanger including the aforementioned heat exchanger baffle assembly structure.

[0016] The advantages of this utility model are:

[0017] 1. This solution achieves the clamping between the baffle plate and the inner wall of the cylinder by setting a guide slot on the outer edge of the baffle plate and setting a transition component including a first mating surface and a third mating surface. The first mating surface and the guide slot are wedge-shaped in the axial direction of the cylinder. The third mating surface is adapted to abut against the inner wall of the cylinder in the final state of the baffle plate assembly. It should be understood that the so-called final state is that after the baffle plate is installed into the cylinder, the transition component is pulled. The first mating surface of the transition component moves relative to the baffle plate which is fixed to the cylinder along the helix angle of the wedge-shaped fit through the guide slot until it moves to the third mating surface and abuts against the inner wall of the cylinder.

[0018] 2. This solution uses a transition component to set a second mating surface. The second mating surface engages with the wedge-shaped guide groove, and the wedge-shaped orientation of the second mating surface is opposite to that of the first mating surface. This design allows the operator to selectively pull the transition component from both ends of the heat exchanger shell after the baffle is installed inside the shell, depending on the operating conditions, to achieve a tight fit between the baffle and the inner wall of the shell.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "butt" should be interpreted broadly. For example, "butt" can refer to the transition, interference fit, or presence of a certain amount of gap between two parts.

[0029] In this embodiment of the invention, relational terms such as "first" and "second" are used merely to distinguish one component from another that has the same name, and do not necessarily require or imply any such actual relationship or order between the components.

[0030] In the description of embodiments of this utility model, the term "comprising" or any other variations thereof is intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Example

[0031] like Figure 1-3 As shown, this disclosure provides a heat exchanger baffle assembly structure, including a baffle 2 and a cylinder 1. The outer edge of the baffle 2 is provided with a guide slot 21 that extends through the axial direction of the cylinder 1. It also includes a transition component 3, which is arranged along the axial direction of the cylinder 1. The transition component 3 includes a first mating surface 31 and a third mating surface 33. The first mating surface 31 is adapted to realize a wedge-shaped fit between the transition component 3 and the guide slot 21 along the axial direction of the cylinder 1. The third mating surface 33 is adapted to abut against the inner wall of the cylinder 1 in the final state of the baffle 2 assembly.

[0032] The heat exchanger shell 1 and baffle 2 involved in this disclosure are conventional components in the art and will not be described in detail. The principle of this disclosure is as follows: the first mating surface 31 of the transition component 3 has a wedge-shaped structure. Before assembling the baffle 2 and the transition component 3 into the shell 1, the narrow part of the transition component 3 can be stuck in the guide slot 21. In this way, after the transition component 3 and the baffle 2 are assembled into a sub-assembly, the radial dimension of the outermost edge of the entire sub-assembly is smaller than the inner diameter of the shell 1, which ensures that the baffle 2 and the transition component 3 can be smoothly installed. After installation, the transition component 3 is pulled along the axial direction of the shell 1. The transition component 3 moves along the wedge-shaped rise angle through the first mating surface 31 until the third mating surface 33 abuts against the inner wall of the shell 1.

[0033] By providing a guide slot 21 on the outer edge of the baffle plate 2 and by providing a transition component 3 including a first mating surface 31 and a third mating surface 33, the first mating surface 31 and the guide slot 21 are wedge-shapedly engaged along the axial direction of the cylinder 1. The third mating surface 33 is adapted to abut against the inner wall of the cylinder 1 in the final state of the baffle plate 2 assembly. It should be understood that the so-called final state is that after the baffle plate 2 is installed in the cylinder 1, the transition component 3 is pulled. The first mating surface 31 of the transition component 3 moves relative to the baffle plate 2, which is fixed to the cylinder 1, through the guide slot 21 along the wedge-shaped engagement angle, until it moves to the third mating surface 33 and abuts against the inner wall of the cylinder 1, thus achieving the clamping between the baffle plate 2 and the inner wall of the cylinder 1. Example

[0034] like Figure 4 As shown, this is the second embodiment of the present disclosure. Based on the first embodiment, the baffle 2 is provided in multiple locations along the axial direction of the cylinder 1, and the first mating surface 31 is provided in multiple locations along the length direction of the transition component 3 and respectively wedges with the multiple guide slots 21 of the baffle 2 along the axial direction of the cylinder 1. Example

[0035] like Figure 5-7As shown, this is the third embodiment of the present disclosure. Based on embodiment two, the transition component 3 further includes a second mating surface 32. The second mating surface 32 is adapted to achieve a wedge-shaped fit between the transition component 3 and the guide slot 21 along the axial direction of the cylinder 1, and the wedge-shaped orientation of the second mating surface 32 is opposite to that of the first mating surface 31. The opposite wedge-shaped orientation in this disclosure means that the wedge angles are in opposite directions. By setting the second mating surface 32 on the transition component 3, the second mating surface 32 engages with the guide slot 21 in a wedge shape, and the wedge-shaped orientation of the second mating surface 32 is opposite to that of the first mating surface 31. This configuration allows the operator to selectively pull the transition component 3 from both ends of the heat exchanger cylinder 1 according to the operating conditions after the baffle 2 is installed inside the cylinder 1, thus achieving a tight fit between the baffle 2 and the inner wall of the cylinder 1.

[0036] Optionally, the second mating surface 32 is provided in multiple locations along the length direction of the transition component 3 and respectively engages with multiple guide slots 21 of the baffle plate 2 in a wedge shape along the axial direction of the cylinder 1.

[0037] Optionally, adjacent first mating surfaces 31 and second mating surfaces 32 form a wedge-shaped gap H1. Within the wedge-shaped gap H1 section, the interior angle β formed by the first mating surfaces 31 and the second mating surfaces 32 is set radially inward along the cylinder 1. Furthermore, in the final state of the baffle plate 2 assembly, the intersection position of the first mating surfaces 31 and the second mating surfaces 32 within the wedge-shaped gap H1 section is offset from the guide slot 21.

[0038] Optionally, adjacent baffles 2 form a plate spacing H2; along the axial direction of the cylinder 1, the plate spacing H2 and the wedge spacing H1 are arranged in an overlapping and staggered manner.

[0039] By setting multiple first mating surfaces 31 and multiple second mating surfaces 32, and by overlapping and staggering the wedge-shaped interval H1 with the plate spacing H2, the efficiency and effectiveness of the transition component 3 are improved.

[0040] Optionally, the included angles between the first mating surface 31, the second mating surface 32, and the third mating surface 33 are all α, where 3°≤α≤15°.

[0041] Optionally, the transition component 3 is configured as a plate with a thickness of δ, where δ = 5-10 mm; the guide slot 21 has a width of w, where w ≥ 1.1δ.

[0042] Optionally, the transition component 3 is provided at least 3 times along the outer edge of the baffle 2.

[0043] This disclosure also provides a heat exchanger including the above-described heat exchanger baffle assembly structure.

[0044] The above are merely specific embodiments of this disclosure, enabling those skilled in the art to understand or implement this disclosure. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this disclosure. Therefore, this disclosure is not to be limited to these embodiments, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
