Description

Technical Field

[0001] This utility model relates to the field of heat exchangers, and in particular to a heat exchanger tube bundle that prevents water leakage. Background Technology

[0002] A heat exchanger is a device used to transfer heat between two or more fluids at different temperatures. In a wall-type heat exchanger, two fluids at different temperatures flow in a space separated by a wall. Heat exchange between the two fluids is achieved through heat conduction through the wall and convection of the fluids on the wall surface.

[0003] When heat exchangers exchange heat with fluids, they typically use pipes to transport the liquid, and depending on the pipe installation layout, adjacent pipes are usually directly connected and installed using flanges and fixing bolts.

[0004] When flange plates and fixing bolts are used directly, the connection between the two pipes will have a misaligned prestress due to factors such as installation position and gravity. When the prestress acts on the flange plate and fixing bolts, it will not only affect the service life of the bolts, but also cause cracks between the flange plates, thus creating certain defects.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides, for example Figure 1-3 The diagram shows a heat exchanger tube bundle designed to prevent water leakage.

[0035] Example 1

[0036] The system includes a conveying pipe 1 and a connecting assembly 2. The connecting assembly 2 is located at the end of the conveying pipe 1 and is used to splice and fix adjacent conveying pipes 1. The connecting assembly 2 includes a connecting pipe 21, a positioning collar 22, a flange plate 23, a fixing bolt 24, a fixing nut, and a locking assembly 25. The outer wall of the connecting pipe 21 is slidably sleeved with the conveying pipe 1. The connecting pipe 21 can connect two conveying pipes 1, preventing misalignment due to gravity difference and improving the stability of the connection. The positioning collar 22 is fixedly sleeved on the connecting pipe 1. Externally, flange plate 23 is fixedly installed on the end of the outer wall of conveying pipe 1. Flange plate 23 is located on the side of positioning collar 22. Fixing bolt 24 is located on flange plate 23 and positioning collar 22. Fixing nut is threaded onto one end of the outer wall of fixing bolt 24. Locking component 25 is snapped onto the outside of flange plate 23. Locking component 25 can lock the two flange plates 23, thereby ensuring the stability of the installation of the two flange plates 23 and preventing the fixing bolt 24 from loosening and the two flange plates 23 from separating directly.

[0037] Furthermore, the locking assembly 25 includes a snap-fit ​​element 251, a snap-fit ​​rack 252, and a sealing gasket. The snap-fit ​​element 251 is fitted onto the outside of the two flange plates 23, thereby locking the distance between the two flange plates 23. The snap-fit ​​element 251 and the flange plates 23 have inclined slopes on their opposite sides, allowing the snap-fit ​​element 251 to move towards the center of the flange plates 23. The more securely the snap-fit ​​element 251 engages the two flange plates 23, the less pressure the fixing bolts 24 will exert on the flange plates 23 later. When fixed, the toothed rack 252 is fixedly connected to the inner wall of the snap-fit ​​part 251 under the applied force, and the outer wall of the toothed rack 252 is slidably snapped into the flange plate 23. The toothed rack 252 can improve the stability of the snap-fit ​​part 251 snapped into the outside of the two flange plates 23, that is, improve the friction between the snap-fit ​​part 251 and the flange plate 23. The sealing gasket is set between the flange plate 23 and the positioning collar 22. The sealing gasket can improve the sealing performance between the positioning collar 22 and the two flange plates 23, that is, improve the sealing performance at the connection of the two conveying pipes 1.

[0038] Example 2

[0039] Based on Embodiment 1, the locking assembly 25 further includes a connecting plate 253, a fixing sleeve 254, and a sliding hole 255. The connecting plate 253 is disposed on the side of the snap-fit ​​member 251. A through hole matching the fixing bolt 24 is opened on one side of the connecting plate 253, so that the fixing bolt 24 passes through the through hole and can limit the connection plate 253. The fixing sleeve 254 is fixedly connected to the side of the connecting plate 253 facing the snap-fit ​​member 251. The sliding hole 255 is opened on one side of the snap-fit ​​member 251. The outer wall of the fixing sleeve 254 is slidably sleeved with the inner cavity of the sliding hole 255. The length of the fixing sleeve 254 is greater than the thickness of one side of the snap-fit ​​member 251. So that when the fixing bolt 24 and the fixing nut squeeze the two connecting plates 253, the connecting plates 253 do not contact the side of the snap-fit ​​member 251.

[0040] Furthermore, the locking assembly 25 also includes a pressing block 256 and a connecting hole 257. The pressing block 256 is fixedly connected to one side of the connecting plate 253, and the connecting hole 257 is opened on one side of the snap-fit ​​member 251. The outer wall of the pressing block 256 is slidably sleeved with the inner cavity of the connecting hole 257. One side of the pressing block 256 and one side of the inner wall of the connecting hole 257 are provided with corresponding inclined surfaces. Thus, while the vertical distance between the connecting plate 253 and the center line of the flange plate 23 remains unchanged, the distance between the two connecting plates 253 is reduced. The fixing sleeve 254 on the opposite side of the two connecting plates 253 can press and fix the flange plate 23. The connecting plate 253 can press the snap-fit ​​member 251 towards the center of the flange plate 23 through the pressing block 256, thereby ensuring the stability of the snap-fit ​​member 251 snapping the two flange plates 23. The fixing bolt 24 and the fixing nut are used to press the corresponding connecting plate 253, so that the connecting plate 253 is pressed and locked to the flange plate 23 through the fixing sleeve 254.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
