Technical Field

[0001] This utility model relates to the technical field of heat pump generator tube sheet connection structure, and in particular to a gas absorption air source heat pump generator tube sheet connection structure. Background Technology

[0002] A gas absorption air source heat pump generator is a device that uses gas as an energy source to transfer heat and heat the air through an absorption refrigeration cycle. It is widely used in building heating and industrial heat source systems. It efficiently utilizes gas energy, achieving energy conservation and environmental protection goals, while online monitoring and control systems ensure operational safety and stability, improving the overall performance and reliability of the heat pump system.

[0003] Traditional tubesheet connection structures typically consist of a tubesheet body, tube holes, seals, and fasteners. The tubesheet body supports the tube bundle and ensures overall positioning; the tube holes provide passageways for the tubes; the seals prevent media leakage; and the fasteners secure the tubesheet to other components, ensuring connection stability and sealing.

[0004] Traditional tubesheet connection structures suffer from low strength, primarily due to design and material limitations, as well as the tendency for stress concentration under prolonged high temperature and pressure conditions. Insufficient strength can lead to tubesheet deformation or leakage during operation, reducing system sealing and stability. Over long-term use, this low strength accelerates damage to pipes and connections, increases maintenance costs, affects the thermal efficiency and operational safety of gas absorption heat pumps, and may even cause equipment failure or safety accidents. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a tube sheet connection structure for a gas absorption air source heat pump generator, aiming to improve the problem that the traditional tube sheet connection structure has low strength, which affects the thermal efficiency and operational safety of the gas absorption heat pump, and may even cause equipment failure or safety accidents.

[0018] 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.

[0019] Reference Figures 1-2 The present invention provides an embodiment of a gas absorption air source heat pump generator tube sheet connection structure, including a plate 1, which is made of stainless steel and serves to support the connecting components and tanks 4, providing overall structural support. This is common knowledge and will not be described in detail here. Multiple tanks 4 are provided on the side wall of the plate 1, and connecting components are provided inside the plate 1. The connecting assembly includes multiple connectors 2, which fix the flat expansion tube 3 to the plate 1, thereby providing an installation base for the flat expansion tube 3 and preventing the flat expansion tube 3 from detaching from the plate 1 under stress. One end of each connector 2 is fixedly connected to the inside of the plate 1, and each connector 2 corresponds to each tank 4, thereby avoiding excessive local stress caused by the concentrated connection of multiple tanks 4 and extending the service life of the overall structure. The side wall of each connector 2 is fixedly connected to the flat expansion tube 3. The flat expansion tube 3 compensates for the gap of the threaded connection through its own slight plastic deformation, thereby enhancing the tightness of the fit with the tank 4 and reducing the risk of medium leakage. The flat expansion tube 3 has an internal thread 5, and one end of the tank 4 is provided with an external thread 6. The external thread 6 and the internal thread 5 are threadedly connected. The internal thread 5 engages with the external thread 6 to form a mechanical lock through the mutual interlocking of the threads, achieving the effect of detachable fixing of the plate 1 and the tank 4, which facilitates the maintenance and replacement of the tank 4 in the future. The side wall of the plate 1 is provided with a disassembly and assembly assembly.

[0020] Reference Figure 3 and Figure 4 The assembly includes a side housing 7, which works with the plate 1 to form a protective space, protecting the connecting components and internal piping, thus preventing external environmental corrosion of the core components and extending the equipment's service life. The side housing 7 is located on the side wall of the plate 1. Multiple fasteners 8 are fixedly connected to both the plate 1 and the side housing 7. The fasteners 8 provide mounting holes for the positioning posts 10, enabling precise alignment between the plate 1 and the side housing 7 and preventing misalignment during connection. Each fastener 8 has a circular hole 9 inside, and a positioning post 10 is positioned between the fasteners 8. The positioning post 10 slides within the circular hole 9, which provides a sliding channel for the positioning post 10. With the insertion of the positioning post 10, the initial positioning of the plate 1 and the side housing 7 is achieved. A connecting post 11 is fixedly connected to the side wall of the positioning post 10, and a side post 12 is fixedly connected to the side wall of the connecting post 11. The side post 12 carries the positioning groove 16 and the positioning bead 17, serving as a lock. The fixed structure provides the mounting base. The side column 12 has multiple positioning grooves 16 inside and multiple positioning beads 17 inside. The positioning beads 17 are slidably connected inside the positioning grooves 16. The positioning column 10 has a sliding column 13 slidably connected inside. The positioning beads 17 engage with the positioning grooves 16 to achieve axial locking of the side column 12 through the engagement of the beads and grooves, thus preventing the positioning column 10 from coming out of the round hole 9. One end of the sliding column 13 is fixedly connected to a push ring 15, which is slidably connected inside the side column 12. A spring 18 is sleeved on the outer wall of the sliding column 13. One end of the spring 18 is fixedly connected to the outer wall of the sliding column 13, and the other end of the spring 18 is fixedly connected to the inside of the positioning column 10. The other end of the sliding column 13 is fixedly connected to an operating shaft 14. The operating shaft 14 allows the operator to manually pull the sliding column 13 to overcome the elastic force of the spring 18 and make the push ring 15 retract, thereby releasing the engagement between the positioning beads 17 and the positioning grooves 16 and achieving the effect of quick disassembly.

[0021] Working principle: The flat expansion tube 3 on the side wall of connector 2 engages with the external thread 6 at one end of tank body 4 through the internal thread 5. The threaded connection itself provides basic connection strength and sealing. The flat expansion tube 3 can compensate for the thread gap through slight plastic deformation, further enhancing the tightness of the fit, reducing the risk of media leakage, avoiding the insufficient strength problem caused by concentrated stress in traditional structures, ensuring stable connection under high temperature and high pressure conditions, and guaranteeing the thermal efficiency and operational safety of the heat pump generator. After the fixing parts 8 of plate body 1 and side shell 7 are aligned through the round hole 9, The positioning pin 10 is inserted into the round hole 9 to achieve initial positioning. In its natural state, the spring 18 on the outer wall of the sliding pin 13 is in an extended state. The push ring 15 pushes the positioning bead 17 under the action of the spring force, so that the positioning bead 17 is locked into the positioning groove 16 of the side pin 12 to prevent the positioning pin 10 from loosening. When disassembly is required, the operating shaft 14 is pulled to drive the sliding pin 13 to compress the spring 18. The push ring 15 moves back to release the pushing force on the positioning bead 17. The positioning bead 17 is disengaged from the positioning groove 16, and the positioning pin 10 can be pulled out to achieve separation. This takes into account both connection stability and maintenance convenience.
