Description

Technical Field

[0001] This application relates to the field of heat exchanger technology, and in particular to a tube bundle structure that is easy to install. Background Technology

[0002] A heat exchanger is a device that facilitates heat transfer between two or more fluids at different temperatures. Commonly used heat exchangers include shell-and-tube heat exchangers and floating head heat exchangers. A shell-and-tube heat exchanger consists of a shell and a tube bundle structure housed within the shell. The tube bundle structure comprises several heat exchange tubes and several baffles, with the heat exchange tubes passing through the baffles. During operation, the high flow rate and velocity of the fluid entering the shell-and-tube heat exchanger can easily cause the heat exchange tubes to sway, resulting in impacts between the tubes and the baffles. This can lead to wear and tear on the tube bundle, and prolonged use can cause damage or bending of the tube bundle. Utility Model Content

[0003] The purpose of this application is to provide a tube bundle structure that is easy to install, which reduces wear on the heat exchange tubes due to impact while also facilitating the installation of the heat exchange tubes.

[0004] The tube bundle structure provided in this application adopts the following technical solution for easy installation:

[0005] An easy-to-install tube bundle structure, comprising:

[0006] A baffle plate, wherein the baffle plate is provided with perforations;

[0007] Heat exchange tube, which is slidably disposed within the perforation;

[0008] The mounting block is slidably disposed within the perforation, and the heat exchange tube is mounted on the mounting block;

[0009] An elastic element is disposed within the perforation, with one end acting on the mounting block and the other end acting on the inner wall of the perforation;

[0010] A limiting component is disposed on the mounting block and is used to limit the sliding of the mounting block.

[0011] Optionally, the limiting component includes a limiting plate and a first slider. A first groove is formed on one side wall of the perforation and a second groove is formed on the other side wall. The first slider is fixed to the side wall of the limiting plate. The first slider can be inserted into the first groove and slide within the first groove. The limiting plate is slidably disposed on the mounting block and can slide towards the second groove and be inserted into the second groove. The limiting plate can slide within the second groove. When the limiting plate is inserted into the second groove, the first slider separates from the first groove.

[0012] Optionally, a guide slope is provided in the first slide groove, and the guide slope is inclined from top to bottom towards the second slide groove.

[0013] Optionally, a second slider is slidably disposed on the limiting plate, and the elastic element is fixed on the second slider.

[0014] Optionally, the mounting block is made of an elastic material.

[0015] Optionally, the perforated bottom wall is provided with a receiving groove, one end of the elastic element is disposed in the receiving groove, and the other end of the elastic element extends out of the receiving groove and acts on the mounting block.

[0016] This application utilizes an elastic element to cushion the heat exchange tube when it is impacted, thereby reducing the impact force and potential damage. Furthermore, during heat exchange tube installation, the inner wall of the first groove restricts the sliding of the limiting plate, ensuring that the distance between the mounting block and the inner wall of the perforation is greater than the outer diameter of the heat exchange tube. This facilitates installation and reduces the difficulty of perforating the heat exchange tube during installation. Attached Figure Description

Detailed Implementation

[0020] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail below.

[0021] A tube bundle structure that is easy to install, see reference. Figure 1 and Figure 2 It includes baffles 1 and heat exchange tubes 2. Several baffles 1 are provided, and the baffles 1 are evenly spaced and staggered along the axis of the heat exchange tubes 2. Several perforations 11 are provided on each baffle 1. Several heat exchange tubes 2 are provided, and each heat exchange tube 2 is inserted into the corresponding perforation 11 and slidably disposed in the perforation 11.

[0022] The structure inside each perforation 11 is the same. The following description uses one of the perforations 11 as an example to introduce the structure between the heat exchange tube 2 and the perforation 11.

[0023] A mounting block 3 is slidably disposed within the perforation 11. In this embodiment, fluid flows into the heat exchanger from above, so the mounting block 3 is slidably disposed vertically within the perforation 11. The heat exchange tube 2 rests on the mounting block 3. An elastic element 4 is disposed between the mounting block 3 and the inner wall of the perforation 11. One end of the elastic element 4 acts on the mounting block 3, and the other end acts on the inner wall of the perforation 11. When the heat exchange tube 2 is impacted by fluid, the elastic element 4 undergoes elastic deformation, thereby buffering the heat exchange tube 2, reducing the impact force on the heat exchange tube 2, and thus reducing the possibility of damage to the heat exchange tube 2.

[0024] Furthermore, a receiving groove 12 is provided on the inner bottom wall of the perforation 11. One end of the elastic element 4 is disposed in the receiving groove 12, and the other end extends out of the receiving groove 12 and acts on the mounting block 3. In this embodiment, the elastic element 4 is a spring. When the impact force of the fluid on the heat exchange tube 2 is too large, it is easy to cause the elastic element 4 to be over-compressed, resulting in the elastic element 4 being unable to recover. By setting the receiving groove 12, a part of the elastic element 4 is disposed in the receiving groove 12. When the impact force on the heat exchange tube 2 is too large, the mounting block 3 will be limited by the inner wall of the perforation 11, thereby ensuring that the elastic element 4 is not over-compressed and ensuring the service life of the elastic element 4.

[0025] Furthermore, the mounting block 3 is made of an elastic material; in this embodiment, it is made of rubber. When the fluid exerts excessive impact on the heat exchange tube 2, the mounting block 3 is restricted from sliding by the inner wall of the perforation 11. At this time, the mounting block 3 will undergo elastic deformation, providing secondary buffering for the heat exchange tube 2, thereby further reducing the possibility of damage to the heat exchange tube 2 due to excessive impact.

[0026] Furthermore, the tube bundle structure also includes a limiting component 5, which is used to restrict the sliding of the mounting block 3. In the initial stage, the mounting block 3 is limited by the limiting component 5, restricting the sliding of the mounting block 3. At this time, the elastic element 4 is compressed, and the height between the mounting block 3 and the inner wall of the perforation 11 is greater than the outer diameter of the heat exchange tube 2, thereby facilitating the insertion of the heat exchange tube 2 into the perforation 11. After the heat exchange tube 2 is inserted into the perforation 11, the restriction on the mounting block 3 is released. At this time, the elastic element 4 returns to its original state, causing the mounting block 3 to slide, thereby clamping the heat exchange tube 2 between the mounting block 3 and the inner wall of the perforation 11.

[0027] Specifically, the limiting component 5 includes a limiting plate 51 and a first slider 52. The limiting plate 51 is disposed between the elastic member 4 and the mounting block 3. The elastic member 4 acts on the limiting plate 51 and thus acts on the mounting block 3. The limiting plate 51 is slidably disposed on the mounting block 3. A first sliding groove 13 is provided on one inner sidewall of the through hole 11, and a second sliding groove 14 is provided on the other inner sidewall. The first slider 52 is fixed on the sidewall of the limiting plate 51. The first slider 52 can be inserted into the first sliding groove 13 and slide within the first sliding groove 13. The limiting plate 51 can slide away from the first sliding groove 13 and thus be inserted into the second sliding groove 14 and slide within the second sliding groove 14.

[0028] When the first slider 52 abuts against the inner bottom wall of the first slide groove 13, the limiting block is restricted from sliding, and the elastic element 4 is compressed. At this time, the distance between the mounting block 3 and the through hole 11 is greater than the outer diameter of the heat exchange tube 2, which facilitates the installation of the heat exchange tube 2. When the heat exchange tube 2 is inserted into the through hole 11, the limiting plate 51 is inserted into the second slide groove 14. At this time, the first slider 52 separates from the first slide groove 13, thereby releasing the limitation on the limiting plate 51. The elastic element 4 then returns to its original state, causing the limiting plate 51 to slide, so that the mounting block 3 and the inner wall of the through hole 11 clamp the heat exchange tube 2.

[0029] Furthermore, the inner wall of the first slide groove 13 is provided with a guide slope 131, which is inclined from top to bottom towards the second slide groove 14. When the heat exchange tube 2 is inserted into the perforation 11 and overlaps the mounting block 3, the heat exchange tube is pressed downward, causing the first slider 52 to slide downward. Under the guidance of the guide slope 131, it separates from the first slide groove 13, and the limiting plate 51 is inserted into the second slide groove 14. By setting the guide slope 131, it is easier for the installer to move the limiting plate 51.

[0030] Furthermore, a second slider 53 is slidably provided on the limiting plate 51, and the elastic element 4 is fixed on the second slider 53. Because the second slider 53 is provided, the second slider 53 can slide on the limiting plate 51 during the sliding process of the limiting plate 51, thereby reducing the occurrence of radial bending of the elastic element 4 and ensuring the service life of the elastic element 4.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
